[Bug]: Blank page on location change / reload if a filesystem asynchronous call was pending
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
17.1.1
### What operating system are you using?
Windows
### Operating System Version
Windows 10 21H2
### What arch are you using?
x64
### Last Known Working Electron version
13.6.9
### Expected Behavior
Assuming a BrowserWindow like this:
```
const mainWindow = new BrowserWindow({
...
webPreferences: {
nodeIntegration: true,
contextIsolation: false,
}
})
```
And an asynchronous filesystem call on `fs.promises` API
```
// renderer.js
const fs = require('fs');
async function asyncStuff() {
let output = await fs.promises.readFile("datafile");
}
```
Then trying to reload the page when the fs asynchronous call is not finished yet will make the page fail (blank page).
```
// renderer.js
async function testCrash() {
asyncStuff() // No await here
window.location.reload() // Here the renderer will crash
})
```
I expect that the page reloads correctly.
### Actual Behavior
The page is blank, and DevTools are disconnected.
### Testcase Gist URL
_No response_
### Additional Information
Notes:
* Replace the `fs.promises.readFile()` by `fs.readFileSync()` and the page will reload fine
* Replace the `fs.promises.readFile()` by `fs.readFile() with callback` and the page will reload fine
* The bug is here also with a `window.location.href`
* I tried with other async api and the page works fine (like `https.get()`, `timers.promises.setTimeout()`, or `fetch()`)
I created a repo to reproduce the bug: https://github.com/remss/electron-issue-reload
Just run `npm i && npm start` then click on `reloadMeWithAsyncStuff` button to see the blank page.

BrowserWindow.fromWebContents returns undefined for windows created using window.open
|
### Preflight Checklist
* [x] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/master/CONTRIBUTING.md) for this project.
* [x] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/master/CODE_OF_CONDUCT.md) that this project adheres to.
* [x] I have searched the issue tracker for an issue that matches the one I want to file, without success.
### Issue Details
* **Electron Version:** 5.0.7
* **Operating System:** Windows 10
### Expected Behavior
I expect that calling `BrowserWindow.fromWebContents(win.webContents)` returns `win`.
### Actual Behavior
The API returns `undefined`.
### To Reproduce
```
const { app, BrowserWindow } = require('electron')
async function createWindow() {
var mainWindow = new BrowserWindow({
webPreferences: {
nativeWindowOpen: true
}
});
await mainWindow.loadURL("https://google.com");
mainWindow.webContents.openDevTools();
console.log(BrowserWindow.fromWebContents(mainWindow.webContents)); // correctly returns mainWindow
app.on("browser-window-created", (e, window) => {
console.log(BrowserWindow.fromWebContents(window.webContents)); // returns undefined
window.once("will-move", (e) => {
console.log(BrowserWindow.fromWebContents(e.sender)); // extra test; also returns undefined
});
});
}
app.on('ready', createWindow)
```
Run `npm start` and open a window from devtools (e.g. `window.open("https://google.com")`). Notice that `fromWebContents` can't find the browser window for the new window.

BrowserWindow.fromWebContents returns undefined for windows created using window.open
|
### Preflight Checklist
* [x] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/master/CONTRIBUTING.md) for this project.
* [x] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/master/CODE_OF_CONDUCT.md) that this project adheres to.
* [x] I have searched the issue tracker for an issue that matches the one I want to file, without success.
### Issue Details
* **Electron Version:** 5.0.7
* **Operating System:** Windows 10
### Expected Behavior
I expect that calling `BrowserWindow.fromWebContents(win.webContents)` returns `win`.
### Actual Behavior
The API returns `undefined`.
### To Reproduce
```
const { app, BrowserWindow } = require('electron')
async function createWindow() {
var mainWindow = new BrowserWindow({
webPreferences: {
nativeWindowOpen: true
}
});
await mainWindow.loadURL("https://google.com");
mainWindow.webContents.openDevTools();
console.log(BrowserWindow.fromWebContents(mainWindow.webContents)); // correctly returns mainWindow
app.on("browser-window-created", (e, window) => {
console.log(BrowserWindow.fromWebContents(window.webContents)); // returns undefined
window.once("will-move", (e) => {
console.log(BrowserWindow.fromWebContents(e.sender)); // extra test; also returns undefined
});
});
}
app.on('ready', createWindow)
```
Run `npm start` and open a window from devtools (e.g. `window.open("https://google.com")`). Notice that `fromWebContents` can't find the browser window for the new window.

[Bug]: callback didn't executed with process.nextTick and setImmediate
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/master/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/master/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a feature request that matches the one I want to file, without success.
### Electron Version
13.1.4
### What operating system are you using?
Windows
### Operating System Version
10
### What arch are you using?
x64
### Last Known Working Electron version
not
### Expected Behavior
callbacks added by setImmediate and process.nextTick executed normally.
### Actual Behavior
After I reload my project with ctrl +R,something was wrong.
And I run those code in dev tool's console.
```
setImmediate(()=>{
console.log("immediate")
})
process.nextTick(()=>{
console.log("nextTick")
})
```
but console.log didn't show the log,and callback added by setTimeout works at the same time.
I read the source code,found some comment
```
// setImmediate and process.nextTick makes use of uv_check and uv_prepare to
// run the callbacks, however since we only run uv loop on requests, the
// callbacks wouldn't be called until something else activated the uv loop,
// which would delay the callbacks for arbitrary long time. So we should
// initiatively activate the uv loop once setImmediate and process.nextTick is
// called.
```
Is electron use different event loop from nodejs?
Any idea what's going on?
### Testcase Gist URL
_No response_
### Additional Information
This bug is occasional.

### Electron Version
13.1.4
### What operating system are you using?
Windows
### Operating System Version
10
### What arch are you using?
x64
### Last Known Working Electron version
not
### Expected Behavior
callbacks added by setImmediate and process.nextTick executed normally.
### Actual Behavior
After I reload my project with ctrl +R,something was wrong.
And I run those code in dev tool's console.
```
setImmediate(()=>{
console.log("immediate")
})
process.nextTick(()=>{
console.log("nextTick")
})
```
but console.log didn't show the log,and callback added by setTimeout works at the same time.
I read the source code,found some comment
```
// setImmediate and process.nextTick makes use of uv_check and uv_prepare to
// run the callbacks, however since we only run uv loop on requests, the
// callbacks wouldn't be called until something else activated the uv loop,
// which would delay the callbacks for arbitrary long time. So we should
// initiatively activate the uv loop once setImmediate and process.nextTick is
// called.
```
Is electron use different event loop from nodejs?
Any idea what's going on?
### Testcase Gist URL

callbacks added by setImmediate and process.nextTick executed normally.
### Actual Behavior
After I reload my project with ctrl +R,something was wrong.
And I run those code in dev tool's console.
```
setImmediate(()=>{
console.log("immediate")
})
process.nextTick(()=>{
console.log("nextTick")
})
```
but console.log didn't show the log,and callback added by setTimeout works at the same time.
I read the source code,found some comment
```
// setImmediate and process.nextTick makes use of uv_check and uv_prepare to
// run the callbacks, however since we only run uv loop on requests, the
// callbacks wouldn't be called until something else activated the uv loop,
// which would delay the callbacks for arbitrary long time. So we should
// initiatively activate the uv loop once setImmediate and process.nextTick is
// called.
```
Is electron use different event loop from nodejs?
Any idea what's going on?

[Bug]: callback didn't executed with process.nextTick and setImmediate

### Electron Version
13.1.4
### What operating system are you using?
Windows
### Operating System Version
10
### What arch are you using?
x64
### Last Known Working Electron version
not
### Expected Behavior
callbacks added by setImmediate and process.nextTick executed normally.
### Actual Behavior
After I reload my project with ctrl +R,something was wrong.
And I run those code in dev tool's console.
```
setImmediate(()=>{
console.log("immediate")
})
process.nextTick(()=>{
console.log("nextTick")
})
```
but console.log didn't show the log,and callback added by setTimeout works at the same time.
I read the source code,found some comment
```
// setImmediate and process.nextTick makes use of uv_check and uv_prepare to
// run the callbacks, however since we only run uv loop on requests, the
// callbacks wouldn't be called until something else activated the uv loop,
// which would delay the callbacks for arbitrary long time. So we should
// initiatively activate the uv loop once setImmediate and process.nextTick is
// called.
```
Is electron use different event loop from nodejs?
Any idea what's going on?

[Bug]: callback didn't executed with process.nextTick and setImmediate

### Preflight Checklist

### Electron Version
13.1.4
### What operating system are you using?
Windows
### Operating System Version
10
### What arch are you using?
x64
### Last Known Working Electron version
not
### Expected Behavior
callbacks added by setImmediate and process.nextTick executed normally.
### Actual Behavior
After I reload my project with ctrl +R,something was wrong.
And I run those code in dev tool's console.
```
setImmediate(()=>{
console.log("immediate")
})
process.nextTick(()=>{
console.log("nextTick")
})
```
but console.log didn't show the log,and callback added by setTimeout works at the same time.
I read the source code,found some comment
```
// setImmediate and process.nextTick makes use of uv_check and uv_prepare to
// run the callbacks, however since we only run uv loop on requests, the
// callbacks wouldn't be called until something else activated the uv loop,
// which would delay the callbacks for arbitrary long time. So we should
// initiatively activate the uv loop once setImmediate and process.nextTick is
// called.
```
Is electron use different event loop from nodejs?
Any idea what's going on?

DCHECK on frameless window resize
|
Frameless windows created on Windows DCHECK with a Views hierachy event reception failure.
<details> <summary>Stacktrace</summary>
```
[17168:0131/153326.410:FATAL:native_view_host.cc(248)] Check failed: false. This view is not expected to receive events directly. Event targeting should find the native view as target window instead of the view hierarchy. This is likely due to an overlapping View that receives but is not handling this event. See crbug.com/1263413 and Widget::ShouldDescendIntoChildForEventHandling() for some more leads. If the overlapping view was not intended to receive events, call SetCanProcessEventsWithinSubtree(false) on the overlapping View that paints to a layer. If it's intended to receive some, but not this event, event targeting needs to be fixed for this case.
View: NativeViewHost
Hierarchy:
RootView -> NonClientView -> WinFrameView -> ClientView -> View -> View -> WebView -> NativeViewHost

DCHECK on frameless window resize
|
Frameless windows created on Windows DCHECK with a Views hierachy event reception failure.
<details> <summary>Stacktrace</summary>
```
[17168:0131/153326.410:FATAL:native_view_host.cc(248)] Check failed: false. This view is not expected to receive events directly. Event targeting should find the native view as target window instead of the view hierarchy. This is likely due to an overlapping View that receives but is not handling this event. See crbug.com/1263413 and Widget::ShouldDescendIntoChildForEventHandling() for some more leads. If the overlapping view was not intended to receive events, call SetCanProcessEventsWithinSubtree(false) on the overlapping View that paints to a layer. If it's intended to receive some, but not this event, event targeting needs to be fixed for this case.
View: NativeViewHost

# BrowserWindow
> Create and control browser windows.
Process: [Main](../glossary.md#main-process)
```javascript
// In the main process.
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
// Load a remote URL
win.loadURL('https://github.com')
// Or load a local HTML file
win.loadFile('index.html')
```
## Window customization
The `BrowserWindow` class exposes various ways to modify the look and behavior of
your app's windows. For more details, see the [Window Customization](../tutorial/window-customization.md)
tutorial.
## Showing the window gracefully
When loading a page in the window directly, users may see the page load incrementally,
which is not a good experience for a native app. To make the window display
without a visual flash, there are two solutions for different situations.
### Using the `ready-to-show` event
While loading the page, the `ready-to-show` event will be emitted when the renderer
process has rendered the page for the first time if the window has not been shown yet. Showing
the window after this event will have no visual flash:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ show: false })
win.once('ready-to-show', () => {
win.show()
})
```
This event is usually emitted after the `did-finish-load` event, but for
pages with many remote resources, it may be emitted before the `did-finish-load`
event.
Please note that using this event implies that the renderer will be considered "visible" and
paint even though `show` is false. This event will never fire if you use `paintWhenInitiallyHidden: false`
### Setting the `backgroundColor` property
For a complex app, the `ready-to-show` event could be emitted too late, making
the app feel slow. In this case, it is recommended to show the window
immediately, and use a `backgroundColor` close to your app's background:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ backgroundColor: '#2e2c29' })
win.loadURL('https://github.com')
```
Note that even for apps that use `ready-to-show` event, it is still recommended
to set `backgroundColor` to make the app feel more native.
Some examples of valid `backgroundColor` values include:
```js
const win = new BrowserWindow()
win.setBackgroundColor('hsl(230, 100%, 50%)')
win.setBackgroundColor('rgb(255, 145, 145)')
win.setBackgroundColor('#ff00a3')
win.setBackgroundColor('blueviolet')
```
For more information about these color types see valid options in [win.setBackgroundColor](browser-window.md#winsetbackgroundcolorbackgroundcolor).
## Parent and child windows
By using `parent` option, you can create child windows:
```javascript
const { BrowserWindow } = require('electron')
const top = new BrowserWindow()
const child = new BrowserWindow({ parent: top })
child.show()
top.show()
```
The `child` window will always show on top of the `top` window.
## Modal windows
A modal window is a child window that disables parent window, to create a modal
window, you have to set both `parent` and `modal` options:
```javascript
const { BrowserWindow } = require('electron')
const child = new BrowserWindow({ parent: top, modal: true, show: false })
child.loadURL('https://github.com')
child.once('ready-to-show', () => {
child.show()
})
```
## Page visibility
The [Page Visibility API][page-visibility-api] works as follows:
* On all platforms, the visibility state tracks whether the window is
hidden/minimized or not.
* Additionally, on macOS, the visibility state also tracks the window
occlusion state. If the window is occluded (i.e. fully covered) by another
window, the visibility state will be `hidden`. On other platforms, the
visibility state will be `hidden` only when the window is minimized or
explicitly hidden with `win.hide()`.
* If a `BrowserWindow` is created with `show: false`, the initial visibility
state will be `visible` despite the window actually being hidden.
* If `backgroundThrottling` is disabled, the visibility state will remain
`visible` even if the window is minimized, occluded, or hidden.
It is recommended that you pause expensive operations when the visibility
state is `hidden` in order to minimize power consumption.
## Platform notices
* On macOS modal windows will be displayed as sheets attached to the parent window.
* On macOS the child windows will keep the relative position to parent window
when parent window moves, while on Windows and Linux child windows will not
move.
* On Linux the type of modal windows will be changed to `dialog`.
* On Linux many desktop environments do not support hiding a modal window.
## Class: BrowserWindow
> Create and control browser windows.
Process: [Main](../glossary.md#main-process)
`BrowserWindow` is an [EventEmitter][event-emitter].
It creates a new `BrowserWindow` with native properties as set by the `options`.
### `new BrowserWindow([options])`
* `options` Object (optional)
* `width` Integer (optional) - Window's width in pixels. Default is `800`.
* `height` Integer (optional) - Window's height in pixels. Default is `600`.
* `x` Integer (optional) - (**required** if y is used) Window's left offset from screen.
Default is to center the window.
* `y` Integer (optional) - (**required** if x is used) Window's top offset from screen.
Default is to center the window.
* `useContentSize` boolean (optional) - The `width` and `height` would be used as web
page's size, which means the actual window's size will include window
frame's size and be slightly larger. Default is `false`.
* `center` boolean (optional) - Show window in the center of the screen. Default is `false`.
* `minWidth` Integer (optional) - Window's minimum width. Default is `0`.
* `minHeight` Integer (optional) - Window's minimum height. Default is `0`.
* `maxWidth` Integer (optional) - Window's maximum width. Default is no limit.
* `maxHeight` Integer (optional) - Window's maximum height. Default is no limit.
* `resizable` boolean (optional) - Whether window is resizable. Default is `true`.
* `movable` boolean (optional) - Whether window is movable. This is not implemented
on Linux. Default is `true`.
* `minimizable` boolean (optional) - Whether window is minimizable. This is not
implemented on Linux. Default is `true`.
* `maximizable` boolean (optional) - Whether window is maximizable. This is not
implemented on Linux. Default is `true`.
* `closable` boolean (optional) - Whether window is closable. This is not implemented
on Linux. Default is `true`.
* `focusable` boolean (optional) - Whether the window can be focused. Default is
`true`. On Windows setting `focusable: false` also implies setting
`skipTaskbar: true`. On Linux setting `focusable: false` makes the window
stop interacting with wm, so the window will always stay on top in all
workspaces.
* `alwaysOnTop` boolean (optional) - Whether the window should always stay on top of
other windows. Default is `false`.
* `fullscreen` boolean (optional) - Whether the window should show in fullscreen. When
explicitly set to `false` the fullscreen button will be hidden or disabled
on macOS. Default is `false`.
* `fullscreenable` boolean (optional) - Whether the window can be put into fullscreen
mode. On macOS, also whether the maximize/zoom button should toggle full
screen mode or maximize window. Default is `true`.
* `simpleFullscreen` boolean (optional) - Use pre-Lion fullscreen on macOS. Default is `false`.
* `skipTaskbar` boolean (optional) - Whether to show the window in taskbar. Default is
`false`.
* `kiosk` boolean (optional) - Whether the window is in kiosk mode. Default is `false`.
* `title` string (optional) - Default window title. Default is `"Electron"`. If the HTML tag `<title>` is defined in the HTML file loaded by `loadURL()`, this property will be ignored.
* `icon` ([NativeImage](native-image.md) | string) (optional) - The window icon. On Windows it is
recommended to use `ICO` icons to get best visual effects, you can also
leave it undefined so the executable's icon will be used.
* `show` boolean (optional) - Whether window should be shown when created. Default is
`true`.
* `paintWhenInitiallyHidden` boolean (optional) - Whether the renderer should be active when `show` is `false` and it has just been created. In order for `document.visibilityState` to work correctly on first load with `show: false` you should set this to `false`. Setting this to `false` will cause the `ready-to-show` event to not fire. Default is `true`.
* `frame` boolean (optional) - Specify `false` to create a
[frameless window](../tutorial/window-customization.md#create-frameless-windows). Default is `true`.
* `parent` BrowserWindow (optional) - Specify parent window. Default is `null`.
* `modal` boolean (optional) - Whether this is a modal window. This only works when the
window is a child window. Default is `false`.
* `acceptFirstMouse` boolean (optional) - Whether clicking an inactive window will also
click through to the web contents. Default is `false` on macOS. This option is not
configurable on other platforms.
* `disableAutoHideCursor` boolean (optional) - Whether to hide cursor when typing.
Default is `false`.
* `autoHideMenuBar` boolean (optional) - Auto hide the menu bar unless the `Alt`
key is pressed. Default is `false`.
* `enableLargerThanScreen` boolean (optional) - Enable the window to be resized larger
than screen. Only relevant for macOS, as other OSes allow
larger-than-screen windows by default. Default is `false`.
* `backgroundColor` string (optional) - The window's background color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. Alpha in #AARRGGBB format is supported if `transparent` is set to `true`. Default is `#FFF` (white). See [win.setBackgroundColor](browser-window.md#winsetbackgroundcolorbackgroundcolor) for more information.
* `hasShadow` boolean (optional) - Whether window should have a shadow. Default is `true`.
* `opacity` number (optional) - Set the initial opacity of the window, between 0.0 (fully
transparent) and 1.0 (fully opaque). This is only implemented on Windows and macOS.
* `darkTheme` boolean (optional) - Forces using dark theme for the window, only works on
some GTK+3 desktop environments. Default is `false`.
* `transparent` boolean (optional) - Makes the window [transparent](../tutorial/window-customization.md#create-transparent-windows).
Default is `false`. On Windows, does not work unless the window is frameless.
* `type` string (optional) - The type of window, default is normal window. See more about
this below.
* `visualEffectState` string (optional) - Specify how the material appearance should reflect window activity state on macOS. Must be used with the `vibrancy` property. Possible values are:
* `followWindow` - The backdrop should automatically appear active when the window is active, and inactive when it is not. This is the default.
* `active` - The backdrop should always appear active.
* `inactive` - The backdrop should always appear inactive.
* `titleBarStyle` string (optional) _macOS_ _Windows_ - The style of window title bar.
Default is `default`. Possible values are:
* `default` - Results in the standard title bar for macOS or Windows respectively.
* `hidden` - Results in a hidden title bar and a full size content window. On macOS, the window still has the standard window controls (“traffic lights”) in the top left. On Windows, when combined with `titleBarOverlay: true` it will activate the Window Controls Overlay (see `titleBarOverlay` for more information), otherwise no window controls will be shown.
* `hiddenInset` - Only on macOS, results in a hidden title bar with an alternative look
where the traffic light buttons are slightly more inset from the window edge.
* `customButtonsOnHover` - Only on macOS, results in a hidden title bar and a full size
content window, the traffic light buttons will display when being hovered
over in the top left of the window. **Note:** This option is currently
experimental.
* `trafficLightPosition` [Point](structures/point.md) (optional) - Set a
custom position for the traffic light buttons in frameless windows.
* `roundedCorners` boolean (optional) - Whether frameless window should have
rounded corners on macOS. Default is `true`.
* `fullscreenWindowTitle` boolean (optional) _Deprecated_ - Shows the title in
the title bar in full screen mode on macOS for `hiddenInset` titleBarStyle.
Default is `false`.
* `thickFrame` boolean (optional) - Use `WS_THICKFRAME` style for frameless windows on
Windows, which adds standard window frame. Setting it to `false` will remove
window shadow and window animations. Default is `true`.
* `vibrancy` string (optional) - Add a type of vibrancy effect to the window, only on
macOS. Can be `appearance-based`, `light`, `dark`, `titlebar`, `selection`,
`menu`, `popover`, `sidebar`, `medium-light`, `ultra-dark`, `header`, `sheet`, `window`, `hud`, `fullscreen-ui`, `tooltip`, `content`, `under-window`, or `under-page`. Please note that `appearance-based`, `light`, `dark`, `medium-light`, and `ultra-dark` are deprecated and have been removed in macOS Catalina (10.15).
* `zoomToPageWidth` boolean (optional) - Controls the behavior on macOS when
option-clicking the green stoplight button on the toolbar or by clicking the
Window > Zoom menu item. If `true`, the window will grow to the preferred
width of the web page when zoomed, `false` will cause it to zoom to the
width of the screen. This will also affect the behavior when calling
`maximize()` directly. Default is `false`.
* `tabbingIdentifier` string (optional) - Tab group name, allows opening the
window as a native tab on macOS 10.12+. Windows with the same tabbing
identifier will be grouped together. This also adds a native new tab button
to your window's tab bar and allows your `app` and window to receive the
`new-window-for-tab` event.
* `webPreferences` Object (optional) - Settings of web page's features.
* `devTools` boolean (optional) - Whether to enable DevTools. If it is set to `false`, can not use `BrowserWindow.webContents.openDevTools()` to open DevTools. Default is `true`.
* `nodeIntegration` boolean (optional) - Whether node integration is enabled.
Default is `false`.
* `nodeIntegrationInWorker` boolean (optional) - Whether node integration is
enabled in web workers. Default is `false`. More about this can be found
in [Multithreading](../tutorial/multithreading.md).
* `nodeIntegrationInSubFrames` boolean (optional) - Experimental option for
enabling Node.js support in sub-frames such as iframes and child windows. All your preloads will load for
every iframe, you can use `process.isMainFrame` to determine if you are
in the main frame or not.
* `preload` string (optional) - Specifies a script that will be loaded before other
scripts run in the page. This script will always have access to node APIs
no matter whether node integration is turned on or off. The value should
be the absolute file path to the script.
When node integration is turned off, the preload script can reintroduce
Node global symbols back to the global scope. See example
[here](context-bridge.md#exposing-node-global-symbols).
* `sandbox` boolean (optional) - If set, this will sandbox the renderer
associated with the window, making it compatible with the Chromium
OS-level sandbox and disabling the Node.js engine. This is not the same as
the `nodeIntegration` option and the APIs available to the preload script
are more limited. Read more about the option [here](../tutorial/sandbox.md).
* `session` [Session](session.md#class-session) (optional) - Sets the session used by the
page. Instead of passing the Session object directly, you can also choose to
use the `partition` option instead, which accepts a partition string. When
both `session` and `partition` are provided, `session` will be preferred.
Default is the default session.
* `partition` string (optional) - Sets the session used by the page according to the
session's partition string. If `partition` starts with `persist:`, the page
will use a persistent session available to all pages in the app with the
same `partition`. If there is no `persist:` prefix, the page will use an
in-memory session. By assigning the same `partition`, multiple pages can share
the same session. Default is the default session.
* `zoomFactor` number (optional) - The default zoom factor of the page, `3.0` represents
`300%`. Default is `1.0`.
* `javascript` boolean (optional) - Enables JavaScript support. Default is `true`.
* `webSecurity` boolean (optional) - When `false`, it will disable the
same-origin policy (usually using testing websites by people), and set
`allowRunningInsecureContent` to `true` if this options has not been set
by user. Default is `true`.
* `allowRunningInsecureContent` boolean (optional) - Allow an https page to run
JavaScript, CSS or plugins from http URLs. Default is `false`.
* `images` boolean (optional) - Enables image support. Default is `true`.
* `imageAnimationPolicy` string (optional) - Specifies how to run image animations (E.g. GIFs). Can be `animate`, `animateOnce` or `noAnimation`. Default is `animate`.
* `textAreasAreResizable` boolean (optional) - Make TextArea elements resizable. Default
is `true`.
* `webgl` boolean (optional) - Enables WebGL support. Default is `true`.
* `plugins` boolean (optional) - Whether plugins should be enabled. Default is `false`.
* `experimentalFeatures` boolean (optional) - Enables Chromium's experimental features.
Default is `false`.
* `scrollBounce` boolean (optional) - Enables scroll bounce (rubber banding) effect on
macOS. Default is `false`.
* `enableBlinkFeatures` string (optional) - A list of feature strings separated by `,`, like
`CSSVariables,KeyboardEventKey` to enable. The full list of supported feature
strings can be found in the [RuntimeEnabledFeatures.json5][runtime-enabled-features]
file.
* `disableBlinkFeatures` string (optional) - A list of feature strings separated by `,`,
like `CSSVariables,KeyboardEventKey` to disable. The full list of supported
feature strings can be found in the
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
* `defaultFontFamily` Object (optional) - Sets the default font for the font-family.
* `standard` string (optional) - Defaults to `Times New Roman`.
* `serif` string (optional) - Defaults to `Times New Roman`.
* `sansSerif` string (optional) - Defaults to `Arial`.
* `monospace` string (optional) - Defaults to `Courier New`.
* `cursive` string (optional) - Defaults to `Script`.
* `fantasy` string (optional) - Defaults to `Impact`.
* `defaultFontSize` Integer (optional) - Defaults to `16`.
* `defaultMonospaceFontSize` Integer (optional) - Defaults to `13`.
* `minimumFontSize` Integer (optional) - Defaults to `0`.
* `defaultEncoding` string (optional) - Defaults to `ISO-8859-1`.
* `backgroundThrottling` boolean (optional) - Whether to throttle animations and timers
when the page becomes background. This also affects the
[Page Visibility API](#page-visibility). Defaults to `true`.
* `offscreen` boolean (optional) - Whether to enable offscreen rendering for the browser
window. Defaults to `false`. See the
[offscreen rendering tutorial](../tutorial/offscreen-rendering.md) for
more details.
* `contextIsolation` boolean (optional) - Whether to run Electron APIs and
the specified `preload` script in a separate JavaScript context. Defaults
to `true`. The context that the `preload` script runs in will only have
access to its own dedicated `document` and `window` globals, as well as
its own set of JavaScript builtins (`Array`, `Object`, `JSON`, etc.),
which are all invisible to the loaded content. The Electron API will only
be available in the `preload` script and not the loaded page. This option
should be used when loading potentially untrusted remote content to ensure
the loaded content cannot tamper with the `preload` script and any
Electron APIs being used. This option uses the same technique used by
[Chrome Content Scripts][chrome-content-scripts]. You can access this
context in the dev tools by selecting the 'Electron Isolated Context'
entry in the combo box at the top of the Console tab.
* `webviewTag` boolean (optional) - Whether to enable the [`<webview>` tag](webview-tag.md).
Defaults to `false`. **Note:** The
`preload` script configured for the `<webview>` will have node integration
enabled when it is executed so you should ensure remote/untrusted content
is not able to create a `<webview>` tag with a possibly malicious `preload`
script. You can use the `will-attach-webview` event on [webContents](web-contents.md)
to strip away the `preload` script and to validate or alter the
`<webview>`'s initial settings.
* `additionalArguments` string[] (optional) - A list of strings that will be appended
to `process.argv` in the renderer process of this app. Useful for passing small
bits of data down to renderer process preload scripts.
* `safeDialogs` boolean (optional) - Whether to enable browser style
consecutive dialog protection. Default is `false`.
* `safeDialogsMessage` string (optional) - The message to display when
consecutive dialog protection is triggered. If not defined the default
message would be used, note that currently the default message is in
English and not localized.
* `disableDialogs` boolean (optional) - Whether to disable dialogs
completely. Overrides `safeDialogs`. Default is `false`.
* `navigateOnDragDrop` boolean (optional) - Whether dragging and dropping a
file or link onto the page causes a navigation. Default is `false`.
* `autoplayPolicy` string (optional) - Autoplay policy to apply to
content in the window, can be `no-user-gesture-required`,
`user-gesture-required`, `document-user-activation-required`. Defaults to
`no-user-gesture-required`.
* `disableHtmlFullscreenWindowResize` boolean (optional) - Whether to
prevent the window from resizing when entering HTML Fullscreen. Default
is `false`.
* `accessibleTitle` string (optional) - An alternative title string provided only
to accessibility tools such as screen readers. This string is not directly
visible to users.
* `spellcheck` boolean (optional) - Whether to enable the builtin spellchecker.
Default is `true`.
* `enableWebSQL` boolean (optional) - Whether to enable the [WebSQL api](https://www.w3.org/TR/webdatabase/).
Default is `true`.
* `v8CacheOptions` string (optional) - Enforces the v8 code caching policy
used by blink. Accepted values are
* `none` - Disables code caching
* `code` - Heuristic based code caching
* `bypassHeatCheck` - Bypass code caching heuristics but with lazy compilation
* `bypassHeatCheckAndEagerCompile` - Same as above except compilation is eager.
Default policy is `code`.
* `enablePreferredSizeMode` boolean (optional) - Whether to enable
preferred size mode. The preferred size is the minimum size needed to
contain the layout of the document—without requiring scrolling. Enabling
this will cause the `preferred-size-changed` event to be emitted on the
`WebContents` when the preferred size changes. Default is `false`.
* `titleBarOverlay` Object | Boolean (optional) - When using a frameless window in conjunction with `win.setWindowButtonVisibility(true)` on macOS or using a `titleBarStyle` so that the standard window controls ("traffic lights" on macOS) are visible, this property enables the Window Controls Overlay [JavaScript APIs][overlay-javascript-apis] and [CSS Environment Variables][overlay-css-env-vars]. Specifying `true` will result in an overlay with default system colors. Default is `false`.
* `color` String (optional) _Windows_ - The CSS color of the Window Controls Overlay when enabled. Default is the system color.
* `symbolColor` String (optional) _Windows_ - The CSS color of the symbols on the Window Controls Overlay when enabled. Default is the system color.
* `height` Integer (optional) _macOS_ _Windows_ - The height of the title bar and Window Controls Overlay in pixels. Default is system height.
When setting minimum or maximum window size with `minWidth`/`maxWidth`/
`minHeight`/`maxHeight`, it only constrains the users. It won't prevent you from
passing a size that does not follow size constraints to `setBounds`/`setSize` or
to the constructor of `BrowserWindow`.
The possible values and behaviors of the `type` option are platform dependent.
Possible values are:
* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
`notification`.
* On macOS, possible types are `desktop`, `textured`.
* The `textured` type adds metal gradient appearance
(`NSTexturedBackgroundWindowMask`).
* The `desktop` type places the window at the desktop background window level
(`kCGDesktopWindowLevel - 1`). Note that desktop window will not receive
focus, keyboard or mouse events, but you can use `globalShortcut` to receive
input sparingly.
* On Windows, possible type is `toolbar`.
### Instance Events
Objects created with `new BrowserWindow` emit the following events:
**Note:** Some events are only available on specific operating systems and are
labeled as such.
#### Event: 'page-title-updated'
Returns:
* `event` Event
* `title` string
* `explicitSet` boolean
Emitted when the document changed its title, calling `event.preventDefault()`
will prevent the native window's title from changing.
`explicitSet` is false when title is synthesized from file URL.
#### Event: 'close'
Returns:
* `event` Event
Emitted when the window is going to be closed. It's emitted before the
`beforeunload` and `unload` event of the DOM. Calling `event.preventDefault()`
will cancel the close.
Usually you would want to use the `beforeunload` handler to decide whether the
window should be closed, which will also be called when the window is
reloaded. In Electron, returning any value other than `undefined` would cancel the
close. For example:
```javascript
window.onbeforeunload = (e) => {
console.log('I do not want to be closed')
// Unlike usual browsers that a message box will be prompted to users, returning
// a non-void value will silently cancel the close.
// It is recommended to use the dialog API to let the user confirm closing the
// application.
e.returnValue = false // equivalent to `return false` but not recommended
}
```
_**Note**: There is a subtle difference between the behaviors of `window.onbeforeunload = handler` and `window.addEventListener('beforeunload', handler)`. It is recommended to always set the `event.returnValue` explicitly, instead of only returning a value, as the former works more consistently within Electron._
#### Event: 'closed'
Emitted when the window is closed. After you have received this event you should
remove the reference to the window and avoid using it any more.
#### Event: 'session-end' _Windows_
Emitted when window session is going to end due to force shutdown or machine restart
or session log off.
#### Event: 'unresponsive'
Emitted when the web page becomes unresponsive.
#### Event: 'responsive'
Emitted when the unresponsive web page becomes responsive again.
#### Event: 'blur'
Emitted when the window loses focus.
#### Event: 'focus'
Emitted when the window gains focus.
#### Event: 'show'
Emitted when the window is shown.
#### Event: 'hide'
Emitted when the window is hidden.
#### Event: 'ready-to-show'
Emitted when the web page has been rendered (while not being shown) and window can be displayed without
a visual flash.
Please note that using this event implies that the renderer will be considered "visible" and
paint even though `show` is false. This event will never fire if you use `paintWhenInitiallyHidden: false`
#### Event: 'maximize'
Emitted when window is maximized.
#### Event: 'unmaximize'
Emitted when the window exits from a maximized state.
#### Event: 'minimize'
Emitted when the window is minimized.
#### Event: 'restore'
Emitted when the window is restored from a minimized state.
#### Event: 'will-resize' _macOS_ _Windows_
Returns:
* `event` Event
* `newBounds` [Rectangle](structures/rectangle.md) - Size the window is being resized to.
* `details` Object
* `edge` (string) - The edge of the window being dragged for resizing. Can be `bottom`, `left`, `right`, `top-left`, `top-right`, `bottom-left` or `bottom-right`.
Emitted before the window is resized. Calling `event.preventDefault()` will prevent the window from being resized.
Note that this is only emitted when the window is being resized manually. Resizing the window with `setBounds`/`setSize` will not emit this event.
The possible values and behaviors of the `edge` option are platform dependent. Possible values are:
* On Windows, possible values are `bottom`, `top`, `left`, `right`, `top-left`, `top-right`, `bottom-left`, `bottom-right`.
* On macOS, possible values are `bottom` and `right`.
* The value `bottom` is used to denote vertical resizing.
* The value `right` is used to denote horizontal resizing.
#### Event: 'resize'
Emitted after the window has been resized.
#### Event: 'resized' _macOS_ _Windows_
Emitted once when the window has finished being resized.
This is usually emitted when the window has been resized manually. On macOS, resizing the window with `setBounds`/`setSize` and setting the `animate` parameter to `true` will also emit this event once resizing has finished.
#### Event: 'will-move' _macOS_ _Windows_
Returns:
* `event` Event
* `newBounds` [Rectangle](structures/rectangle.md) - Location the window is being moved to.
Emitted before the window is moved. On Windows, calling `event.preventDefault()` will prevent the window from being moved.
Note that this is only emitted when the window is being moved manually. Moving the window with `setPosition`/`setBounds`/`center` will not emit this event.
#### Event: 'move'
Emitted when the window is being moved to a new position.
#### Event: 'moved' _macOS_ _Windows_
Emitted once when the window is moved to a new position.
__Note__: On macOS this event is an alias of `move`.
#### Event: 'enter-full-screen'
Emitted when the window enters a full-screen state.
#### Event: 'leave-full-screen'
Emitted when the window leaves a full-screen state.
#### Event: 'enter-html-full-screen'
Emitted when the window enters a full-screen state triggered by HTML API.
#### Event: 'leave-html-full-screen'
Emitted when the window leaves a full-screen state triggered by HTML API.
#### Event: 'always-on-top-changed'
Returns:
* `event` Event
* `isAlwaysOnTop` boolean
Emitted when the window is set or unset to show always on top of other windows.
#### Event: 'app-command' _Windows_ _Linux_
Returns:
* `event` Event
* `command` string
Emitted when an [App Command](https://msdn.microsoft.com/en-us/library/windows/desktop/ms646275(v=vs.85).aspx)
is invoked. These are typically related to keyboard media keys or browser
commands, as well as the "Back" button built into some mice on Windows.
Commands are lowercased, underscores are replaced with hyphens, and the
`APPCOMMAND_` prefix is stripped off.
e.g. `APPCOMMAND_BROWSER_BACKWARD` is emitted as `browser-backward`.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.on('app-command', (e, cmd) => {
// Navigate the window back when the user hits their mouse back button
if (cmd === 'browser-backward' && win.webContents.canGoBack()) {
win.webContents.goBack()
}
})
```
The following app commands are explicitly supported on Linux:
* `browser-backward`
* `browser-forward`
#### Event: 'scroll-touch-begin' _macOS_
Emitted when scroll wheel event phase has begun.
#### Event: 'scroll-touch-end' _macOS_
Emitted when scroll wheel event phase has ended.
#### Event: 'scroll-touch-edge' _macOS_
Emitted when scroll wheel event phase filed upon reaching the edge of element.
#### Event: 'swipe' _macOS_
Returns:
* `event` Event
* `direction` string
Emitted on 3-finger swipe. Possible directions are `up`, `right`, `down`, `left`.
The method underlying this event is built to handle older macOS-style trackpad swiping,
where the content on the screen doesn't move with the swipe. Most macOS trackpads are not
configured to allow this kind of swiping anymore, so in order for it to emit properly the
'Swipe between pages' preference in `System Preferences > Trackpad > More Gestures` must be
set to 'Swipe with two or three fingers'.
#### Event: 'rotate-gesture' _macOS_
Returns:
* `event` Event
* `rotation` Float
Emitted on trackpad rotation gesture. Continually emitted until rotation gesture is
ended. The `rotation` value on each emission is the angle in degrees rotated since
the last emission. The last emitted event upon a rotation gesture will always be of
value `0`. Counter-clockwise rotation values are positive, while clockwise ones are
negative.
#### Event: 'sheet-begin' _macOS_
Emitted when the window opens a sheet.
#### Event: 'sheet-end' _macOS_
Emitted when the window has closed a sheet.
#### Event: 'new-window-for-tab' _macOS_
Emitted when the native new tab button is clicked.
#### Event: 'system-context-menu' _Windows_
Returns:
* `event` Event
* `point` [Point](structures/point.md) - The screen coordinates the context menu was triggered at
Emitted when the system context menu is triggered on the window, this is
normally only triggered when the user right clicks on the non-client area
of your window. This is the window titlebar or any area you have declared
as `-webkit-app-region: drag` in a frameless window.
Calling `event.preventDefault()` will prevent the menu from being displayed.
### Static Methods

A `string` property that defines an alternative title provided only to
accessibility tools such as screen readers. This string is not directly
visible to users.
### Instance Methods
Objects created with `new BrowserWindow` have the following instance methods:
**Note:** Some methods are only available on specific operating systems and are
labeled as such.
#### `win.destroy()`
Force closing the window, the `unload` and `beforeunload` event won't be emitted
for the web page, and `close` event will also not be emitted
for this window, but it guarantees the `closed` event will be emitted.
#### `win.close()`
Try to close the window. This has the same effect as a user manually clicking
the close button of the window. The web page may cancel the close though. See
the [close event](#event-close).
#### `win.focus()`
Focuses on the window.
#### `win.blur()`
Removes focus from the window.
#### `win.isFocused()`
Returns `boolean` - Whether the window is focused.
#### `win.isDestroyed()`
Returns `boolean` - Whether the window is destroyed.
#### `win.show()`
Shows and gives focus to the window.
#### `win.showInactive()`
Shows the window but doesn't focus on it.
#### `win.hide()`
Hides the window.
#### `win.isVisible()`
Returns `boolean` - Whether the window is visible to the user.
#### `win.isModal()`
Returns `boolean` - Whether current window is a modal window.
#### `win.maximize()`
Maximizes the window. This will also show (but not focus) the window if it
isn't being displayed already.
#### `win.unmaximize()`
Unmaximizes the window.
#### `win.isMaximized()`
Returns `boolean` - Whether the window is maximized.
#### `win.minimize()`
Minimizes the window. On some platforms the minimized window will be shown in
the Dock.
#### `win.restore()`
Restores the window from minimized state to its previous state.
#### `win.isMinimized()`
Returns `boolean` - Whether the window is minimized.
#### `win.setFullScreen(flag)`
* `flag` boolean
Sets whether the window should be in fullscreen mode.
#### `win.isFullScreen()`
Returns `boolean` - Whether the window is in fullscreen mode.
#### `win.setSimpleFullScreen(flag)` _macOS_
* `flag` boolean
Enters or leaves simple fullscreen mode.
Simple fullscreen mode emulates the native fullscreen behavior found in versions of macOS prior to Lion (10.7).
#### `win.isSimpleFullScreen()` _macOS_
Returns `boolean` - Whether the window is in simple (pre-Lion) fullscreen mode.
#### `win.isNormal()`
Returns `boolean` - Whether the window is in normal state (not maximized, not minimized, not in fullscreen mode).
#### `win.setAspectRatio(aspectRatio[, extraSize])`
* `aspectRatio` Float - The aspect ratio to maintain for some portion of the
content view.
* `extraSize` [Size](structures/size.md) (optional) _macOS_ - The extra size not to be included while
maintaining the aspect ratio.
This will make a window maintain an aspect ratio. The extra size allows a
developer to have space, specified in pixels, not included within the aspect
ratio calculations. This API already takes into account the difference between a
window's size and its content size.
Consider a normal window with an HD video player and associated controls.
Perhaps there are 15 pixels of controls on the left edge, 25 pixels of controls
on the right edge and 50 pixels of controls below the player. In order to
maintain a 16:9 aspect ratio (standard aspect ratio for HD @1920x1080) within
the player itself we would call this function with arguments of 16/9 and
{ width: 40, height: 50 }. The second argument doesn't care where the extra width and height
are within the content view--only that they exist. Sum any extra width and
height areas you have within the overall content view.
The aspect ratio is not respected when window is resized programmatically with
APIs like `win.setSize`.
#### `win.setBackgroundColor(backgroundColor)`
* `backgroundColor` string - Color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. The alpha channel is optional for the hex type.
Examples of valid `backgroundColor` values:
* Hex
* #fff (shorthand RGB)
* #ffff (shorthand ARGB)
* #ffffff (RGB)
* #ffffffff (ARGB)
* RGB
* rgb\(([\d]+),\s*([\d]+),\s*([\d]+)\)
* e.g. rgb(255, 255, 255)
* RGBA
* rgba\(([\d]+),\s*([\d]+),\s*([\d]+),\s*([\d.]+)\)
* e.g. rgba(255, 255, 255, 1.0)
* HSL
* hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)
* e.g. hsl(200, 20%, 50%)
* HSLA
* hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)
* e.g. hsla(200, 20%, 50%, 0.5)
* Color name
* Options are listed in [SkParseColor.cpp](https://source.chromium.org/chromium/chromium/src/+/main:third_party/skia/src/utils/SkParseColor.cpp;l=11-152;drc=eea4bf52cb0d55e2a39c828b017c80a5ee054148)
* Similar to CSS Color Module Level 3 keywords, but case-sensitive.
* e.g. `blueviolet` or `red`
Sets the background color of the window. See [Setting `backgroundColor`](#setting-the-backgroundcolor-property).
#### `win.previewFile(path[, displayName])` _macOS_
* `path` string - The absolute path to the file to preview with QuickLook. This
is important as Quick Look uses the file name and file extension on the path
to determine the content type of the file to open.
* `displayName` string (optional) - The name of the file to display on the
Quick Look modal view. This is purely visual and does not affect the content
type of the file. Defaults to `path`.
Uses [Quick Look][quick-look] to preview a file at a given path.
#### `win.closeFilePreview()` _macOS_
Closes the currently open [Quick Look][quick-look] panel.
#### `win.setBounds(bounds[, animate])`
* `bounds` Partial<[Rectangle](structures/rectangle.md)>
* `animate` boolean (optional) _macOS_
Resizes and moves the window to the supplied bounds. Any properties that are not supplied will default to their current values.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
// set all bounds properties
win.setBounds({ x: 440, y: 225, width: 800, height: 600 })
// set a single bounds property
win.setBounds({ width: 100 })
// { x: 440, y: 225, width: 100, height: 600 }
console.log(win.getBounds())
```
#### `win.getBounds()`
Returns [`Rectangle`](structures/rectangle.md) - The `bounds` of the window as `Object`.
#### `win.getBackgroundColor()`
Returns `string` - Gets the background color of the window in Hex (`#RRGGBB`) format.
See [Setting `backgroundColor`](#setting-the-backgroundcolor-property).
**Note:** The alpha value is _not_ returned alongside the red, green, and blue values.
#### `win.setContentBounds(bounds[, animate])`
* `bounds` [Rectangle](structures/rectangle.md)
* `animate` boolean (optional) _macOS_
Resizes and moves the window's client area (e.g. the web page) to
the supplied bounds.
#### `win.getContentBounds()`
Returns [`Rectangle`](structures/rectangle.md) - The `bounds` of the window's client area as `Object`.
#### `win.getNormalBounds()`
Returns [`Rectangle`](structures/rectangle.md) - Contains the window bounds of the normal state
**Note:** whatever the current state of the window : maximized, minimized or in fullscreen, this function always returns the position and size of the window in normal state. In normal state, getBounds and getNormalBounds returns the same [`Rectangle`](structures/rectangle.md).

`floating`, `torn-off-menu`, `modal-panel`, `main-menu`, `status`,
`pop-up-menu`, `screen-saver`, and ~~`dock`~~ (Deprecated). The default is
`floating` when `flag` is true. The `level` is reset to `normal` when the
flag is false. Note that from `floating` to `status` included, the window is
placed below the Dock on macOS and below the taskbar on Windows. From
`pop-up-menu` to a higher it is shown above the Dock on macOS and above the
taskbar on Windows. See the [macOS docs][window-levels] for more details.

Since Windows 10 users can [use their PC as tablet](https://support.microsoft.com/en-us/help/17210/windows-10-use-your-pc-like-a-tablet),
under this mode apps can choose to optimize their UI for tablets, such as
enlarging the titlebar and hiding titlebar buttons.
This API returns whether the window is in tablet mode, and the `resize` event
can be be used to listen to changes to tablet mode.
#### `win.getMediaSourceId()`
Returns `string` - Window id in the format of DesktopCapturerSource's id. For example "window:1324:0".
More precisely the format is `window:id:other_id` where `id` is `HWND` on
Windows, `CGWindowID` (`uint64_t`) on macOS and `Window` (`unsigned long`) on
Linux. `other_id` is used to identify web contents (tabs) so within the same
top level window.
#### `win.getNativeWindowHandle()`
Returns `Buffer` - The platform-specific handle of the window.
The native type of the handle is `HWND` on Windows, `NSView*` on macOS, and
`Window` (`unsigned long`) on Linux.

#### `win.setDocumentEdited(edited)` _macOS_
* `edited` boolean
Specifies whether the window’s document has been edited, and the icon in title
bar will become gray when set to `true`.
#### `win.isDocumentEdited()` _macOS_

#### `win.focusOnWebView()`
#### `win.blurWebView()`
#### `win.capturePage([rect])`
* `rect` [Rectangle](structures/rectangle.md) (optional) - The bounds to capture
Returns `Promise<NativeImage>` - Resolves with a [NativeImage](native-image.md)

Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Same as [`webContents.loadURL(url[, options])`](web-contents.md#contentsloadurlurl-options).
The `url` can be a remote address (e.g. `http://`) or a path to a local
HTML file using the `file://` protocol.
To ensure that file URLs are properly formatted, it is recommended to use
Node's [`url.format`](https://nodejs.org/api/url.html#url_url_format_urlobject)
method:
```javascript
const url = require('url').format({
protocol: 'file',
slashes: true,
pathname: require('path').join(__dirname, 'index.html')
})
win.loadURL(url)
```
You can load a URL using a `POST` request with URL-encoded data by doing
the following:
```javascript
win.loadURL('http://localhost:8000/post', {
postData: [{
type: 'rawData',
bytes: Buffer.from('hello=world')
}],
extraHeaders: 'Content-Type: application/x-www-form-urlencoded'
})
```

Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Same as `webContents.loadFile`, `filePath` should be a path to an HTML
file relative to the root of your application. See the `webContents` docs
for more information.
#### `win.reload()`
Same as `webContents.reload`.
#### `win.setMenu(menu)` _Linux_ _Windows_
* `menu` Menu | null
Sets the `menu` as the window's menu bar.
#### `win.removeMenu()` _Linux_ _Windows_
Remove the window's menu bar.
#### `win.setProgressBar(progress[, options])`
* `progress` Double
* `options` Object (optional)
* `mode` string _Windows_ - Mode for the progress bar. Can be `none`, `normal`, `indeterminate`, `error` or `paused`.
Sets progress value in progress bar. Valid range is [0, 1.0].
Remove progress bar when progress < 0;
Change to indeterminate mode when progress > 1.
On Linux platform, only supports Unity desktop environment, you need to specify
the `*.desktop` file name to `desktopName` field in `package.json`. By default,
it will assume `{app.name}.desktop`.
On Windows, a mode can be passed. Accepted values are `none`, `normal`,
`indeterminate`, `error`, and `paused`. If you call `setProgressBar` without a
mode set (but with a value within the valid range), `normal` will be assumed.
#### `win.setOverlayIcon(overlay, description)` _Windows_
* `overlay` [NativeImage](native-image.md) | null - the icon to display on the bottom
right corner of the taskbar icon. If this parameter is `null`, the overlay is
cleared
* `description` string - a description that will be provided to Accessibility
screen readers
Sets a 16 x 16 pixel overlay onto the current taskbar icon, usually used to
convey some sort of application status or to passively notify the user.
#### `win.setHasShadow(hasShadow)`
* `hasShadow` boolean
Sets whether the window should have a shadow.
#### `win.hasShadow()`
Returns `boolean` - Whether the window has a shadow.
#### `win.setOpacity(opacity)` _Windows_ _macOS_
* `opacity` number - between 0.0 (fully transparent) and 1.0 (fully opaque)
Sets the opacity of the window. On Linux, does nothing. Out of bound number
values are clamped to the [0, 1] range.
#### `win.getOpacity()`
Returns `number` - between 0.0 (fully transparent) and 1.0 (fully opaque). On
Linux, always returns 1.
#### `win.setShape(rects)` _Windows_ _Linux_ _Experimental_
* `rects` [Rectangle[]](structures/rectangle.md) - Sets a shape on the window.
Passing an empty list reverts the window to being rectangular.
Setting a window shape determines the area within the window where the system
permits drawing and user interaction. Outside of the given region, no pixels
will be drawn and no mouse events will be registered. Mouse events outside of
the region will not be received by that window, but will fall through to
whatever is behind the window.
#### `win.setThumbarButtons(buttons)` _Windows_
* `buttons` [ThumbarButton[]](structures/thumbar-button.md)
Returns `boolean` - Whether the buttons were added successfully
Add a thumbnail toolbar with a specified set of buttons to the thumbnail image
of a window in a taskbar button layout. Returns a `boolean` object indicates
whether the thumbnail has been added successfully.
The number of buttons in thumbnail toolbar should be no greater than 7 due to
the limited room. Once you setup the thumbnail toolbar, the toolbar cannot be
removed due to the platform's limitation. But you can call the API with an empty
array to clean the buttons.
The `buttons` is an array of `Button` objects:
* `Button` Object
* `icon` [NativeImage](native-image.md) - The icon showing in thumbnail
toolbar.
* `click` Function
* `tooltip` string (optional) - The text of the button's tooltip.
* `flags` string[] (optional) - Control specific states and behaviors of the
button. By default, it is `['enabled']`.
The `flags` is an array that can include following `string`s:
* `enabled` - The button is active and available to the user.
* `disabled` - The button is disabled. It is present, but has a visual state
indicating it will not respond to user action.
* `dismissonclick` - When the button is clicked, the thumbnail window closes
immediately.
* `nobackground` - Do not draw a button border, use only the image.
* `hidden` - The button is not shown to the user.
* `noninteractive` - The button is enabled but not interactive; no pressed
button state is drawn. This value is intended for instances where the button
is used in a notification.
#### `win.setThumbnailClip(region)` _Windows_
* `region` [Rectangle](structures/rectangle.md) - Region of the window
Sets the region of the window to show as the thumbnail image displayed when
hovering over the window in the taskbar. You can reset the thumbnail to be
the entire window by specifying an empty region:
`{ x: 0, y: 0, width: 0, height: 0 }`.
#### `win.setThumbnailToolTip(toolTip)` _Windows_
* `toolTip` string
Sets the toolTip that is displayed when hovering over the window thumbnail
in the taskbar.
#### `win.setAppDetails(options)` _Windows_
* `options` Object
* `appId` string (optional) - Window's [App User Model ID](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391569(v=vs.85).aspx).
It has to be set, otherwise the other options will have no effect.
* `appIconPath` string (optional) - Window's [Relaunch Icon](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391573(v=vs.85).aspx).
* `appIconIndex` Integer (optional) - Index of the icon in `appIconPath`.
Ignored when `appIconPath` is not set. Default is `0`.
* `relaunchCommand` string (optional) - Window's [Relaunch Command](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391571(v=vs.85).aspx).
* `relaunchDisplayName` string (optional) - Window's [Relaunch Display Name](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391572(v=vs.85).aspx).
Sets the properties for the window's taskbar button.
**Note:** `relaunchCommand` and `relaunchDisplayName` must always be set
together. If one of those properties is not set, then neither will be used.
#### `win.showDefinitionForSelection()` _macOS_
Same as `webContents.showDefinitionForSelection()`.
#### `win.setIcon(icon)` _Windows_ _Linux_
* `icon` [NativeImage](native-image.md) | string
Changes window icon.
#### `win.setWindowButtonVisibility(visible)` _macOS_
* `visible` boolean
Sets whether the window traffic light buttons should be visible.
#### `win.setAutoHideMenuBar(hide)`
* `hide` boolean
Sets whether the window menu bar should hide itself automatically. Once set the
menu bar will only show when users press the single `Alt` key.
If the menu bar is already visible, calling `setAutoHideMenuBar(true)` won't hide it immediately.
#### `win.isMenuBarAutoHide()`
Returns `boolean` - Whether menu bar automatically hides itself.
#### `win.setMenuBarVisibility(visible)` _Windows_ _Linux_
* `visible` boolean
Sets whether the menu bar should be visible. If the menu bar is auto-hide, users can still bring up the menu bar by pressing the single `Alt` key.
#### `win.isMenuBarVisible()`
Returns `boolean` - Whether the menu bar is visible.
#### `win.setVisibleOnAllWorkspaces(visible[, options])`
* `visible` boolean
* `options` Object (optional)
* `visibleOnFullScreen` boolean (optional) _macOS_ - Sets whether
the window should be visible above fullscreen windows.
* `skipTransformProcessType` boolean (optional) _macOS_ - Calling
setVisibleOnAllWorkspaces will by default transform the process
type between UIElementApplication and ForegroundApplication to
ensure the correct behavior. However, this will hide the window
and dock for a short time every time it is called. If your window
is already of type UIElementApplication, you can bypass this
transformation by passing true to skipTransformProcessType.
Sets whether the window should be visible on all workspaces.
**Note:** This API does nothing on Windows.
#### `win.isVisibleOnAllWorkspaces()`
Returns `boolean` - Whether the window is visible on all workspaces.
**Note:** This API always returns false on Windows.
#### `win.setIgnoreMouseEvents(ignore[, options])`
* `ignore` boolean
* `options` Object (optional)
* `forward` boolean (optional) _macOS_ _Windows_ - If true, forwards mouse move
messages to Chromium, enabling mouse related events such as `mouseleave`.
Only used when `ignore` is true. If `ignore` is false, forwarding is always
disabled regardless of this value.
Makes the window ignore all mouse events.
All mouse events happened in this window will be passed to the window below
this window, but if this window has focus, it will still receive keyboard
events.
#### `win.setContentProtection(enable)` _macOS_ _Windows_
* `enable` boolean
Prevents the window contents from being captured by other apps.
On macOS it sets the NSWindow's sharingType to NSWindowSharingNone.
On Windows it calls SetWindowDisplayAffinity with `WDA_EXCLUDEFROMCAPTURE`.
For Windows 10 version 2004 and up the window will be removed from capture entirely,
older Windows versions behave as if `WDA_MONITOR` is applied capturing a black window.
#### `win.setFocusable(focusable)` _macOS_ _Windows_
* `focusable` boolean
Changes whether the window can be focused.
On macOS it does not remove the focus from the window.
#### `win.isFocusable()` _macOS_ _Windows_
Returns whether the window can be focused.
#### `win.setParentWindow(parent)`
* `parent` BrowserWindow | null
Sets `parent` as current window's parent window, passing `null` will turn
current window into a top-level window.
#### `win.getParentWindow()`
Returns `BrowserWindow | null` - The parent window or `null` if there is no parent.
#### `win.getChildWindows()`
Returns `BrowserWindow[]` - All child windows.
#### `win.setAutoHideCursor(autoHide)` _macOS_
* `autoHide` boolean
Controls whether to hide cursor when typing.
#### `win.selectPreviousTab()` _macOS_
Selects the previous tab when native tabs are enabled and there are other
tabs in the window.
#### `win.selectNextTab()` _macOS_
Selects the next tab when native tabs are enabled and there are other
tabs in the window.
#### `win.mergeAllWindows()` _macOS_
Merges all windows into one window with multiple tabs when native tabs
are enabled and there is more than one open window.
#### `win.moveTabToNewWindow()` _macOS_
Moves the current tab into a new window if native tabs are enabled and
there is more than one tab in the current window.
#### `win.toggleTabBar()` _macOS_
Toggles the visibility of the tab bar if native tabs are enabled and
there is only one tab in the current window.
#### `win.addTabbedWindow(browserWindow)` _macOS_
* `browserWindow` BrowserWindow
Adds a window as a tab on this window, after the tab for the window instance.
#### `win.setVibrancy(type)` _macOS_
* `type` string | null - Can be `appearance-based`, `light`, `dark`, `titlebar`,
`selection`, `menu`, `popover`, `sidebar`, `medium-light`, `ultra-dark`, `header`, `sheet`, `window`, `hud`, `fullscreen-ui`, `tooltip`, `content`, `under-window`, or `under-page`. See
the [macOS documentation][vibrancy-docs] for more details.
Adds a vibrancy effect to the browser window. Passing `null` or an empty string
will remove the vibrancy effect on the window.
Note that `appearance-based`, `light`, `dark`, `medium-light`, and `ultra-dark` have been
deprecated and will be removed in an upcoming version of macOS.
#### `win.setTrafficLightPosition(position)` _macOS_
* `position` [Point](structures/point.md)
Set a custom position for the traffic light buttons in frameless window.
#### `win.getTrafficLightPosition()` _macOS_
Returns `Point` - The custom position for the traffic light buttons in
frameless window.
#### `win.setTouchBar(touchBar)` _macOS_
* `touchBar` TouchBar | null
Sets the touchBar layout for the current window. Specifying `null` or
`undefined` clears the touch bar. This method only has an effect if the
machine has a touch bar and is running on macOS 10.12.1+.
**Note:** The TouchBar API is currently experimental and may change or be
removed in future Electron releases.
#### `win.setBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md) | null - Attach `browserView` to `win`.
If there are other `BrowserView`s attached, they will be removed from
this window.
#### `win.getBrowserView()` _Experimental_
Returns `BrowserView | null` - The `BrowserView` attached to `win`. Returns `null`
if one is not attached. Throws an error if multiple `BrowserView`s are attached.
#### `win.addBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md)
Replacement API for setBrowserView supporting work with multi browser views.
#### `win.removeBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md)
#### `win.setTopBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md)
Raises `browserView` above other `BrowserView`s attached to `win`.
Throws an error if `browserView` is not attached to `win`.
#### `win.getBrowserViews()` _Experimental_
Returns `BrowserView[]` - an array of all BrowserViews that have been attached
with `addBrowserView` or `setBrowserView`.
**Note:** The BrowserView API is currently experimental and may change or be
removed in future Electron releases.

# Breaking Changes
Breaking changes will be documented here, and deprecation warnings added to JS code where possible, at least [one major version](tutorial/electron-versioning.md#semver) before the change is made.
### Types of Breaking Changes
This document uses the following convention to categorize breaking changes:
* **API Changed:** An API was changed in such a way that code that has not been updated is guaranteed to throw an exception.
* **Behavior Changed:** The behavior of Electron has changed, but not in such a way that an exception will necessarily be thrown.
* **Default Changed:** Code depending on the old default may break, not necessarily throwing an exception. The old behavior can be restored by explicitly specifying the value.
* **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
* **Removed:** An API or feature was removed, and is no longer supported by Electron.
## Planned Breaking API Changes (20.0)
### Default Changed: renderers without `nodeIntegration: true` are sandboxed by default
Previously, renderers that specified a preload script defaulted to being
unsandboxed. This meant that by default, preload scripts had access to Node.js.
In Electron 20, this default has changed. Beginning in Electron 20, renderers
will be sandboxed by default, unless `nodeIntegration: true` or `sandbox: false`
is specified.
If your preload scripts do not depend on Node, no action is needed. If your
preload scripts _do_ depend on Node, either refactor them to remove Node usage
from the renderer, or explicitly specify `sandbox: false` for the relevant
renderers.
## Planned Breaking API Changes (19.0)
*None (yet)*
## Planned Breaking API Changes (18.0)
### Removed: `nativeWindowOpen`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
Since Electron 15, `nativeWindowOpen` has been enabled by default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (17.0)
### Removed: `desktopCapturer.getSources` in the renderer
The `desktopCapturer.getSources` API is now only available in the main process.
This has been changed in order to improve the default security of Electron
apps.
If you need this functionality, it can be replaced as follows:
```js
// Main process
const { ipcMain, desktopCapturer } = require('electron')
ipcMain.handle(
'DESKTOP_CAPTURER_GET_SOURCES',
(event, opts) => desktopCapturer.getSources(opts)
)
```
```js
// Renderer process
const { ipcRenderer } = require('electron')
const desktopCapturer = {
getSources: (opts) => ipcRenderer.invoke('DESKTOP_CAPTURER_GET_SOURCES', opts)
}
```
However, you should consider further restricting the information returned to
the renderer; for instance, displaying a source selector to the user and only
returning the selected source.
### Deprecated: `nativeWindowOpen`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
Since Electron 15, `nativeWindowOpen` has been enabled by default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (16.0)
### Behavior Changed: `crashReporter` implementation switched to Crashpad on Linux
The underlying implementation of the `crashReporter` API on Linux has changed
from Breakpad to Crashpad, bringing it in line with Windows and Mac. As a
result of this, child processes are now automatically monitored, and calling
`process.crashReporter.start` in Node child processes is no longer needed (and
is not advisable, as it will start a second instance of the Crashpad reporter).
There are also some subtle changes to how annotations will be reported on
Linux, including that long values will no longer be split between annotations
appended with `__1`, `__2` and so on, and instead will be truncated at the
(new, longer) annotation value limit.
### Deprecated: `desktopCapturer.getSources` in the renderer
Usage of the `desktopCapturer.getSources` API in the renderer has been
deprecated and will be removed. This change improves the default security of
Electron apps.
See [here](#removed-desktopcapturergetsources-in-the-renderer) for details on
how to replace this API in your app.
## Planned Breaking API Changes (15.0)
### Default Changed: `nativeWindowOpen` defaults to `true`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
`nativeWindowOpen` is no longer experimental, and is now the default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (14.0)
### Removed: `remote` module
The `remote` module was deprecated in Electron 12, and will be removed in
Electron 14. It is replaced by the
[`@electron/remote`](https://github.com/electron/remote) module.
```js
// Deprecated in Electron 12:
const { BrowserWindow } = require('electron').remote
```
```js
// Replace with:
const { BrowserWindow } = require('@electron/remote')
// In the main process:
require('@electron/remote/main').initialize()
```
### Removed: `app.allowRendererProcessReuse`
The `app.allowRendererProcessReuse` property will be removed as part of our plan to
more closely align with Chromium's process model for security, performance and maintainability.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### Removed: Browser Window Affinity
The `affinity` option when constructing a new `BrowserWindow` will be removed
as part of our plan to more closely align with Chromium's process model for security,
performance and maintainability.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### API Changed: `window.open()`
The optional parameter `frameName` will no longer set the title of the window. This now follows the specification described by the [native documentation](https://developer.mozilla.org/en-US/docs/Web/API/Window/open#parameters) under the corresponding parameter `windowName`.
If you were using this parameter to set the title of a window, you can instead use [win.setTitle(title)](api/browser-window.md#winsettitletitle).
### Removed: `worldSafeExecuteJavaScript`
In Electron 14, `worldSafeExecuteJavaScript` will be removed. There is no alternative, please
ensure your code works with this property enabled. It has been enabled by default since Electron
12.
You will be affected by this change if you use either `webFrame.executeJavaScript` or `webFrame.executeJavaScriptInIsolatedWorld`. You will need to ensure that values returned by either of those methods are supported by the [Context Bridge API](api/context-bridge.md#parameter--error--return-type-support) as these methods use the same value passing semantics.
### Removed: BrowserWindowConstructorOptions inheriting from parent windows
Prior to Electron 14, windows opened with `window.open` would inherit
BrowserWindow constructor options such as `transparent` and `resizable` from
their parent window. Beginning with Electron 14, this behavior is removed, and
windows will not inherit any BrowserWindow constructor options from their
parents.
Instead, explicitly set options for the new window with `setWindowOpenHandler`:
```js
webContents.setWindowOpenHandler((details) => {
return {
action: 'allow',
overrideBrowserWindowOptions: {
// ...
}
}
})
```
### Removed: `additionalFeatures`
The deprecated `additionalFeatures` property in the `new-window` and
`did-create-window` events of WebContents has been removed. Since `new-window`
uses positional arguments, the argument is still present, but will always be
the empty array `[]`. (Though note, the `new-window` event itself is
deprecated, and is replaced by `setWindowOpenHandler`.) Bare keys in window
features will now present as keys with the value `true` in the options object.
```js
// Removed in Electron 14
// Triggered by window.open('...', '', 'my-key')
webContents.on('did-create-window', (window, details) => {
if (details.additionalFeatures.includes('my-key')) {
// ...
}
})
// Replace with
webContents.on('did-create-window', (window, details) => {
if (details.options['my-key']) {
// ...
}
})
```
## Planned Breaking API Changes (13.0)
### API Changed: `session.setPermissionCheckHandler(handler)`
The `handler` methods first parameter was previously always a `webContents`, it can now sometimes be `null`. You should use the `requestingOrigin`, `embeddingOrigin` and `securityOrigin` properties to respond to the permission check correctly. As the `webContents` can be `null` it can no longer be relied on.
```js
// Old code
session.setPermissionCheckHandler((webContents, permission) => {
if (webContents.getURL().startsWith('https://google.com/') && permission === 'notification') {
return true
}
return false
})
// Replace with
session.setPermissionCheckHandler((webContents, permission, requestingOrigin) => {
if (new URL(requestingOrigin).hostname === 'google.com' && permission === 'notification') {
return true
}
return false
})
```
### Removed: `shell.moveItemToTrash()`
The deprecated synchronous `shell.moveItemToTrash()` API has been removed. Use
the asynchronous `shell.trashItem()` instead.
```js
// Removed in Electron 13
shell.moveItemToTrash(path)
// Replace with
shell.trashItem(path).then(/* ... */)
```
### Removed: `BrowserWindow` extension APIs
The deprecated extension APIs have been removed:
* `BrowserWindow.addExtension(path)`
* `BrowserWindow.addDevToolsExtension(path)`
* `BrowserWindow.removeExtension(name)`
* `BrowserWindow.removeDevToolsExtension(name)`
* `BrowserWindow.getExtensions()`
* `BrowserWindow.getDevToolsExtensions()`
Use the session APIs instead:
* `ses.loadExtension(path)`
* `ses.removeExtension(extension_id)`
* `ses.getAllExtensions()`
```js
// Removed in Electron 13
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Replace with
session.defaultSession.loadExtension(path)
```
```js
// Removed in Electron 13
BrowserWindow.removeExtension(name)
BrowserWindow.removeDevToolsExtension(name)
// Replace with
session.defaultSession.removeExtension(extension_id)
```
```js
// Removed in Electron 13
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Replace with
session.defaultSession.getAllExtensions()
```
### Removed: methods in `systemPreferences`
The following `systemPreferences` methods have been deprecated:
* `systemPreferences.isDarkMode()`
* `systemPreferences.isInvertedColorScheme()`
* `systemPreferences.isHighContrastColorScheme()`
Use the following `nativeTheme` properties instead:
* `nativeTheme.shouldUseDarkColors`
* `nativeTheme.shouldUseInvertedColorScheme`
* `nativeTheme.shouldUseHighContrastColors`
```js
// Removed in Electron 13
systemPreferences.isDarkMode()
// Replace with
nativeTheme.shouldUseDarkColors
// Removed in Electron 13
systemPreferences.isInvertedColorScheme()
// Replace with
nativeTheme.shouldUseInvertedColorScheme
// Removed in Electron 13
systemPreferences.isHighContrastColorScheme()
// Replace with
nativeTheme.shouldUseHighContrastColors
```
### Deprecated: WebContents `new-window` event
The `new-window` event of WebContents has been deprecated. It is replaced by [`webContents.setWindowOpenHandler()`](api/web-contents.md#contentssetwindowopenhandlerhandler).
```js
// Deprecated in Electron 13
webContents.on('new-window', (event) => {
event.preventDefault()
})
// Replace with
webContents.setWindowOpenHandler((details) => {
return { action: 'deny' }
})
```
## Planned Breaking API Changes (12.0)
### Removed: Pepper Flash support
Chromium has removed support for Flash, and so we must follow suit. See
Chromium's [Flash Roadmap](https://www.chromium.org/flash-roadmap) for more
details.
### Default Changed: `worldSafeExecuteJavaScript` defaults to `true`
In Electron 12, `worldSafeExecuteJavaScript` will be enabled by default. To restore
the previous behavior, `worldSafeExecuteJavaScript: false` must be specified in WebPreferences.
Please note that setting this option to `false` is **insecure**.
This option will be removed in Electron 14 so please migrate your code to support the default
value.
### Default Changed: `contextIsolation` defaults to `true`
In Electron 12, `contextIsolation` will be enabled by default. To restore
the previous behavior, `contextIsolation: false` must be specified in WebPreferences.
We [recommend having contextIsolation enabled](tutorial/security.md#3-enable-context-isolation-for-remote-content) for the security of your application.
Another implication is that `require()` cannot be used in the renderer process unless
`nodeIntegration` is `true` and `contextIsolation` is `false`.
For more details see: https://github.com/electron/electron/issues/23506
### Removed: `crashReporter.getCrashesDirectory()`
The `crashReporter.getCrashesDirectory` method has been removed. Usage
should be replaced by `app.getPath('crashDumps')`.
```js
// Removed in Electron 12
crashReporter.getCrashesDirectory()
// Replace with
app.getPath('crashDumps')
```
### Removed: `crashReporter` methods in the renderer process
The following `crashReporter` methods are no longer available in the renderer
process:
* `crashReporter.start`
* `crashReporter.getLastCrashReport`
* `crashReporter.getUploadedReports`
* `crashReporter.getUploadToServer`
* `crashReporter.setUploadToServer`
* `crashReporter.getCrashesDirectory`
They should be called only from the main process.
See [#23265](https://github.com/electron/electron/pull/23265) for more details.
### Default Changed: `crashReporter.start({ compress: true })`
The default value of the `compress` option to `crashReporter.start` has changed
from `false` to `true`. This means that crash dumps will be uploaded to the
crash ingestion server with the `Content-Encoding: gzip` header, and the body
will be compressed.
If your crash ingestion server does not support compressed payloads, you can
turn off compression by specifying `{ compress: false }` in the crash reporter
options.
### Deprecated: `remote` module
The `remote` module is deprecated in Electron 12, and will be removed in
Electron 14. It is replaced by the
[`@electron/remote`](https://github.com/electron/remote) module.
```js
// Deprecated in Electron 12:
const { BrowserWindow } = require('electron').remote
```
```js
// Replace with:
const { BrowserWindow } = require('@electron/remote')
// In the main process:
require('@electron/remote/main').initialize()
```
### Deprecated: `shell.moveItemToTrash()`
The synchronous `shell.moveItemToTrash()` has been replaced by the new,
asynchronous `shell.trashItem()`.
```js
// Deprecated in Electron 12
shell.moveItemToTrash(path)
// Replace with
shell.trashItem(path).then(/* ... */)
```
## Planned Breaking API Changes (11.0)
### Removed: `BrowserView.{destroy, fromId, fromWebContents, getAllViews}` and `id` property of `BrowserView`
The experimental APIs `BrowserView.{destroy, fromId, fromWebContents, getAllViews}`
have now been removed. Additionally, the `id` property of `BrowserView`
has also been removed.
For more detailed information, see [#23578](https://github.com/electron/electron/pull/23578).
## Planned Breaking API Changes (10.0)
### Deprecated: `companyName` argument to `crashReporter.start()`
The `companyName` argument to `crashReporter.start()`, which was previously
required, is now optional, and further, is deprecated. To get the same
behavior in a non-deprecated way, you can pass a `companyName` value in
`globalExtra`.
```js
// Deprecated in Electron 10
crashReporter.start({ companyName: 'Umbrella Corporation' })
// Replace with
crashReporter.start({ globalExtra: { _companyName: 'Umbrella Corporation' } })
```
### Deprecated: `crashReporter.getCrashesDirectory()`
The `crashReporter.getCrashesDirectory` method has been deprecated. Usage
should be replaced by `app.getPath('crashDumps')`.
```js
// Deprecated in Electron 10
crashReporter.getCrashesDirectory()
// Replace with
app.getPath('crashDumps')
```
### Deprecated: `crashReporter` methods in the renderer process
Calling the following `crashReporter` methods from the renderer process is
deprecated:
* `crashReporter.start`
* `crashReporter.getLastCrashReport`
* `crashReporter.getUploadedReports`
* `crashReporter.getUploadToServer`
* `crashReporter.setUploadToServer`
* `crashReporter.getCrashesDirectory`
The only non-deprecated methods remaining in the `crashReporter` module in the
renderer are `addExtraParameter`, `removeExtraParameter` and `getParameters`.
All above methods remain non-deprecated when called from the main process.
See [#23265](https://github.com/electron/electron/pull/23265) for more details.
### Deprecated: `crashReporter.start({ compress: false })`
Setting `{ compress: false }` in `crashReporter.start` is deprecated. Nearly
all crash ingestion servers support gzip compression. This option will be
removed in a future version of Electron.
### Default Changed: `enableRemoteModule` defaults to `false`
In Electron 9, using the remote module without explicitly enabling it via the
`enableRemoteModule` WebPreferences option began emitting a warning. In
Electron 10, the remote module is now disabled by default. To use the remote
module, `enableRemoteModule: true` must be specified in WebPreferences:
```js
const w = new BrowserWindow({
webPreferences: {
enableRemoteModule: true
}
})
```
We [recommend moving away from the remote
module](https://medium.com/@nornagon/electrons-remote-module-considered-harmful-70d69500f31).
### `protocol.unregisterProtocol`
### `protocol.uninterceptProtocol`
The APIs are now synchronous and the optional callback is no longer needed.
```javascript
// Deprecated
protocol.unregisterProtocol(scheme, () => { /* ... */ })
// Replace with
protocol.unregisterProtocol(scheme)
```
### `protocol.registerFileProtocol`
### `protocol.registerBufferProtocol`
### `protocol.registerStringProtocol`
### `protocol.registerHttpProtocol`
### `protocol.registerStreamProtocol`
### `protocol.interceptFileProtocol`
### `protocol.interceptStringProtocol`
### `protocol.interceptBufferProtocol`
### `protocol.interceptHttpProtocol`
### `protocol.interceptStreamProtocol`
The APIs are now synchronous and the optional callback is no longer needed.
```javascript
// Deprecated
protocol.registerFileProtocol(scheme, handler, () => { /* ... */ })
// Replace with
protocol.registerFileProtocol(scheme, handler)
```
The registered or intercepted protocol does not have effect on current page
until navigation happens.
### `protocol.isProtocolHandled`
This API is deprecated and users should use `protocol.isProtocolRegistered`
and `protocol.isProtocolIntercepted` instead.
```javascript
// Deprecated
protocol.isProtocolHandled(scheme).then(() => { /* ... */ })
// Replace with
const isRegistered = protocol.isProtocolRegistered(scheme)
const isIntercepted = protocol.isProtocolIntercepted(scheme)
```
## Planned Breaking API Changes (9.0)
### Default Changed: Loading non-context-aware native modules in the renderer process is disabled by default
As of Electron 9 we do not allow loading of non-context-aware native modules in
the renderer process. This is to improve security, performance and maintainability
of Electron as a project.
If this impacts you, you can temporarily set `app.allowRendererProcessReuse` to `false`
to revert to the old behavior. This flag will only be an option until Electron 11 so
you should plan to update your native modules to be context aware.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### Deprecated: `BrowserWindow` extension APIs
The following extension APIs have been deprecated:
* `BrowserWindow.addExtension(path)`
* `BrowserWindow.addDevToolsExtension(path)`
* `BrowserWindow.removeExtension(name)`
* `BrowserWindow.removeDevToolsExtension(name)`
* `BrowserWindow.getExtensions()`
* `BrowserWindow.getDevToolsExtensions()`
Use the session APIs instead:
* `ses.loadExtension(path)`
* `ses.removeExtension(extension_id)`
* `ses.getAllExtensions()`
```js
// Deprecated in Electron 9
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Replace with
session.defaultSession.loadExtension(path)
```
```js
// Deprecated in Electron 9
BrowserWindow.removeExtension(name)
BrowserWindow.removeDevToolsExtension(name)
// Replace with
session.defaultSession.removeExtension(extension_id)
```
```js
// Deprecated in Electron 9
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Replace with
session.defaultSession.getAllExtensions()
```
### Removed: `<webview>.getWebContents()`
This API, which was deprecated in Electron 8.0, is now removed.
```js
// Removed in Electron 9.0
webview.getWebContents()
// Replace with
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())
```
### Removed: `webFrame.setLayoutZoomLevelLimits()`
Chromium has removed support for changing the layout zoom level limits, and it
is beyond Electron's capacity to maintain it. The function was deprecated in
Electron 8.x, and has been removed in Electron 9.x. The layout zoom level limits
are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
### Behavior Changed: Sending non-JS objects over IPC now throws an exception
In Electron 8.0, IPC was changed to use the Structured Clone Algorithm,
bringing significant performance improvements. To help ease the transition, the
old IPC serialization algorithm was kept and used for some objects that aren't
serializable with Structured Clone. In particular, DOM objects (e.g. `Element`,
`Location` and `DOMMatrix`), Node.js objects backed by C++ classes (e.g.
`process.env`, some members of `Stream`), and Electron objects backed by C++
classes (e.g. `WebContents`, `BrowserWindow` and `WebFrame`) are not
serializable with Structured Clone. Whenever the old algorithm was invoked, a
deprecation warning was printed.
In Electron 9.0, the old serialization algorithm has been removed, and sending
such non-serializable objects will now throw an "object could not be cloned"
error.
### API Changed: `shell.openItem` is now `shell.openPath`
The `shell.openItem` API has been replaced with an asynchronous `shell.openPath` API.
You can see the original API proposal and reasoning [here](https://github.com/electron/governance/blob/main/wg-api/spec-documents/shell-openitem.md).
## Planned Breaking API Changes (8.0)
### Behavior Changed: Values sent over IPC are now serialized with Structured Clone Algorithm
The algorithm used to serialize objects sent over IPC (through
`ipcRenderer.send`, `ipcRenderer.sendSync`, `WebContents.send` and related
methods) has been switched from a custom algorithm to V8's built-in [Structured
Clone Algorithm][SCA], the same algorithm used to serialize messages for
`postMessage`. This brings about a 2x performance improvement for large
messages, but also brings some breaking changes in behavior.
* Sending Functions, Promises, WeakMaps, WeakSets, or objects containing any
such values, over IPC will now throw an exception, instead of silently
converting the functions to `undefined`.
```js
// Previously:
ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
// => results in { value: 3 } arriving in the main process
// From Electron 8:
ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
// => throws Error("() => {} could not be cloned.")
```
* `NaN`, `Infinity` and `-Infinity` will now be correctly serialized, instead
of being converted to `null`.
* Objects containing cyclic references will now be correctly serialized,
instead of being converted to `null`.
* `Set`, `Map`, `Error` and `RegExp` values will be correctly serialized,
instead of being converted to `{}`.
* `BigInt` values will be correctly serialized, instead of being converted to
`null`.
* Sparse arrays will be serialized as such, instead of being converted to dense
arrays with `null`s.
* `Date` objects will be transferred as `Date` objects, instead of being
converted to their ISO string representation.
* Typed Arrays (such as `Uint8Array`, `Uint16Array`, `Uint32Array` and so on)
will be transferred as such, instead of being converted to Node.js `Buffer`.
* Node.js `Buffer` objects will be transferred as `Uint8Array`s. You can
convert a `Uint8Array` back to a Node.js `Buffer` by wrapping the underlying
`ArrayBuffer`:
```js
Buffer.from(value.buffer, value.byteOffset, value.byteLength)
```
Sending any objects that aren't native JS types, such as DOM objects (e.g.
`Element`, `Location`, `DOMMatrix`), Node.js objects (e.g. `process.env`,
`Stream`), or Electron objects (e.g. `WebContents`, `BrowserWindow`,
`WebFrame`) is deprecated. In Electron 8, these objects will be serialized as
before with a DeprecationWarning message, but starting in Electron 9, sending
these kinds of objects will throw a 'could not be cloned' error.
[SCA]: https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm
### Deprecated: `<webview>.getWebContents()`
This API is implemented using the `remote` module, which has both performance
and security implications. Therefore its usage should be explicit.
```js
// Deprecated
webview.getWebContents()
// Replace with
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())
```
However, it is recommended to avoid using the `remote` module altogether.
```js
// main
const { ipcMain, webContents } = require('electron')
const getGuestForWebContents = (webContentsId, contents) => {
const guest = webContents.fromId(webContentsId)
if (!guest) {
throw new Error(`Invalid webContentsId: ${webContentsId}`)
}
if (guest.hostWebContents !== contents) {
throw new Error('Access denied to webContents')
}
return guest
}
ipcMain.handle('openDevTools', (event, webContentsId) => {
const guest = getGuestForWebContents(webContentsId, event.sender)
guest.openDevTools()
})
// renderer
const { ipcRenderer } = require('electron')
ipcRenderer.invoke('openDevTools', webview.getWebContentsId())
```
### Deprecated: `webFrame.setLayoutZoomLevelLimits()`
Chromium has removed support for changing the layout zoom level limits, and it
is beyond Electron's capacity to maintain it. The function will emit a warning
in Electron 8.x, and cease to exist in Electron 9.x. The layout zoom level
limits are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
### Deprecated events in `systemPreferences`
The following `systemPreferences` events have been deprecated:
* `inverted-color-scheme-changed`
* `high-contrast-color-scheme-changed`
Use the new `updated` event on the `nativeTheme` module instead.
```js
// Deprecated
systemPreferences.on('inverted-color-scheme-changed', () => { /* ... */ })
systemPreferences.on('high-contrast-color-scheme-changed', () => { /* ... */ })
// Replace with
nativeTheme.on('updated', () => { /* ... */ })
```
### Deprecated: methods in `systemPreferences`
The following `systemPreferences` methods have been deprecated:
* `systemPreferences.isDarkMode()`
* `systemPreferences.isInvertedColorScheme()`
* `systemPreferences.isHighContrastColorScheme()`
Use the following `nativeTheme` properties instead:
* `nativeTheme.shouldUseDarkColors`
* `nativeTheme.shouldUseInvertedColorScheme`
* `nativeTheme.shouldUseHighContrastColors`
```js
// Deprecated
systemPreferences.isDarkMode()
// Replace with
nativeTheme.shouldUseDarkColors
// Deprecated
systemPreferences.isInvertedColorScheme()
// Replace with
nativeTheme.shouldUseInvertedColorScheme
// Deprecated
systemPreferences.isHighContrastColorScheme()
// Replace with
nativeTheme.shouldUseHighContrastColors
```
## Planned Breaking API Changes (7.0)
### Deprecated: Atom.io Node Headers URL
This is the URL specified as `disturl` in a `.npmrc` file or as the `--dist-url`
command line flag when building native Node modules. Both will be supported for
the foreseeable future but it is recommended that you switch.
Deprecated: https://atom.io/download/electron
Replace with: https://electronjs.org/headers
### API Changed: `session.clearAuthCache()` no longer accepts options
The `session.clearAuthCache` API no longer accepts options for what to clear, and instead unconditionally clears the whole cache.
```js
// Deprecated
session.clearAuthCache({ type: 'password' })
// Replace with
session.clearAuthCache()
```
### API Changed: `powerMonitor.querySystemIdleState` is now `powerMonitor.getSystemIdleState`
```js
// Removed in Electron 7.0
powerMonitor.querySystemIdleState(threshold, callback)
// Replace with synchronous API
const idleState = powerMonitor.getSystemIdleState(threshold)
```
### API Changed: `powerMonitor.querySystemIdleTime` is now `powerMonitor.getSystemIdleTime`
```js
// Removed in Electron 7.0
powerMonitor.querySystemIdleTime(callback)
// Replace with synchronous API
const idleTime = powerMonitor.getSystemIdleTime()
```
### API Changed: `webFrame.setIsolatedWorldInfo` replaces separate methods
```js
// Removed in Electron 7.0
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)
webFrame.setIsolatedWorldHumanReadableName(worldId, name)
webFrame.setIsolatedWorldSecurityOrigin(worldId, securityOrigin)
// Replace with
webFrame.setIsolatedWorldInfo(
worldId,
{
securityOrigin: 'some_origin',
name: 'human_readable_name',
csp: 'content_security_policy'
})
```
### Removed: `marked` property on `getBlinkMemoryInfo`
This property was removed in Chromium 77, and as such is no longer available.
### Behavior Changed: `webkitdirectory` attribute for `<input type="file"/>` now lists directory contents
The `webkitdirectory` property on HTML file inputs allows them to select folders.
Previous versions of Electron had an incorrect implementation where the `event.target.files`
of the input returned a `FileList` that returned one `File` corresponding to the selected folder.
As of Electron 7, that `FileList` is now list of all files contained within
the folder, similarly to Chrome, Firefox, and Edge
([link to MDN docs](https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/webkitdirectory)).
As an illustration, take a folder with this structure:
```console
folder
├── file1
├── file2
└── file3
```
In Electron <=6, this would return a `FileList` with a `File` object for:
```console
path/to/folder
```
In Electron 7, this now returns a `FileList` with a `File` object for:
```console
/path/to/folder/file3
/path/to/folder/file2
/path/to/folder/file1
```
Note that `webkitdirectory` no longer exposes the path to the selected folder.
If you require the path to the selected folder rather than the folder contents,
see the `dialog.showOpenDialog` API ([link](api/dialog.md#dialogshowopendialogbrowserwindow-options)).
### API Changed: Callback-based versions of promisified APIs
Electron 5 and Electron 6 introduced Promise-based versions of existing
asynchronous APIs and deprecated their older, callback-based counterparts.
In Electron 7, all deprecated callback-based APIs are now removed.
These functions now only return Promises:
* `app.getFileIcon()` [#15742](https://github.com/electron/electron/pull/15742)
* `app.dock.show()` [#16904](https://github.com/electron/electron/pull/16904)

* `inAppPurchase.getProducts()` [#17355](https://github.com/electron/electron/pull/17355)
* `inAppPurchase.purchaseProduct()`[#17355](https://github.com/electron/electron/pull/17355)
* `netLog.stopLogging()` [#16862](https://github.com/electron/electron/pull/16862)

* `session.resolveProxy()` [#17222](https://github.com/electron/electron/pull/17222)
* `session.setProxy()` [#17222](https://github.com/electron/electron/pull/17222)
* `shell.openExternal()` [#16176](https://github.com/electron/electron/pull/16176)
* `webContents.loadFile()` [#15855](https://github.com/electron/electron/pull/15855)
* `webContents.loadURL()` [#15855](https://github.com/electron/electron/pull/15855)
* `webContents.hasServiceWorker()` [#16535](https://github.com/electron/electron/pull/16535)
* `webContents.printToPDF()` [#16795](https://github.com/electron/electron/pull/16795)
* `webContents.savePage()` [#16742](https://github.com/electron/electron/pull/16742)
* `webFrame.executeJavaScript()` [#17312](https://github.com/electron/electron/pull/17312)
* `webFrame.executeJavaScriptInIsolatedWorld()` [#17312](https://github.com/electron/electron/pull/17312)
* `webviewTag.executeJavaScript()` [#17312](https://github.com/electron/electron/pull/17312)
* `win.capturePage()` [#15743](https://github.com/electron/electron/pull/15743)
These functions now have two forms, synchronous and Promise-based asynchronous:
* `dialog.showMessageBox()`/`dialog.showMessageBoxSync()` [#17298](https://github.com/electron/electron/pull/17298)
* `dialog.showOpenDialog()`/`dialog.showOpenDialogSync()` [#16973](https://github.com/electron/electron/pull/16973)
* `dialog.showSaveDialog()`/`dialog.showSaveDialogSync()` [#17054](https://github.com/electron/electron/pull/17054)
## Planned Breaking API Changes (6.0)
### API Changed: `win.setMenu(null)` is now `win.removeMenu()`
```js
// Deprecated
win.setMenu(null)
// Replace with
win.removeMenu()
```
### API Changed: `electron.screen` in the renderer process should be accessed via `remote`
```js
// Deprecated
require('electron').screen
// Replace with
require('electron').remote.screen
```
### API Changed: `require()`ing node builtins in sandboxed renderers no longer implicitly loads the `remote` version
```js
// Deprecated
require('child_process')
// Replace with
require('electron').remote.require('child_process')
// Deprecated
require('fs')
// Replace with
require('electron').remote.require('fs')
// Deprecated
require('os')
// Replace with
require('electron').remote.require('os')
// Deprecated
require('path')
// Replace with
require('electron').remote.require('path')
```
### Deprecated: `powerMonitor.querySystemIdleState` replaced with `powerMonitor.getSystemIdleState`
```js
// Deprecated
powerMonitor.querySystemIdleState(threshold, callback)
// Replace with synchronous API
const idleState = powerMonitor.getSystemIdleState(threshold)
```
### Deprecated: `powerMonitor.querySystemIdleTime` replaced with `powerMonitor.getSystemIdleTime`
```js
// Deprecated
powerMonitor.querySystemIdleTime(callback)
// Replace with synchronous API
const idleTime = powerMonitor.getSystemIdleTime()
```
### Deprecated: `app.enableMixedSandbox()` is no longer needed
```js
// Deprecated
app.enableMixedSandbox()
```
Mixed-sandbox mode is now enabled by default.
### Deprecated: `Tray.setHighlightMode`
Under macOS Catalina our former Tray implementation breaks.
Apple's native substitute doesn't support changing the highlighting behavior.
```js
// Deprecated
tray.setHighlightMode(mode)
// API will be removed in v7.0 without replacement.
```
## Planned Breaking API Changes (5.0)
### Default Changed: `nodeIntegration` and `webviewTag` default to false, `contextIsolation` defaults to true
The following `webPreferences` option default values are deprecated in favor of the new defaults listed below.
| Property | Deprecated Default | New Default |
|----------|--------------------|-------------|
| `contextIsolation` | `false` | `true` |
| `nodeIntegration` | `true` | `false` |
| `webviewTag` | `nodeIntegration` if set else `true` | `false` |
E.g. Re-enabling the webviewTag
```js
const w = new BrowserWindow({
webPreferences: {
webviewTag: true
}
})
```
### Behavior Changed: `nodeIntegration` in child windows opened via `nativeWindowOpen`
Child windows opened with the `nativeWindowOpen` option will always have Node.js integration disabled, unless `nodeIntegrationInSubFrames` is `true`.
### API Changed: Registering privileged schemes must now be done before app ready
Renderer process APIs `webFrame.registerURLSchemeAsPrivileged` and `webFrame.registerURLSchemeAsBypassingCSP` as well as browser process API `protocol.registerStandardSchemes` have been removed.
A new API, `protocol.registerSchemesAsPrivileged` has been added and should be used for registering custom schemes with the required privileges. Custom schemes are required to be registered before app ready.
### Deprecated: `webFrame.setIsolatedWorld*` replaced with `webFrame.setIsolatedWorldInfo`
```js
// Deprecated
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)
webFrame.setIsolatedWorldHumanReadableName(worldId, name)
webFrame.setIsolatedWorldSecurityOrigin(worldId, securityOrigin)
// Replace with
webFrame.setIsolatedWorldInfo(
worldId,
{
securityOrigin: 'some_origin',
name: 'human_readable_name',
csp: 'content_security_policy'
})
```
### API Changed: `webFrame.setSpellCheckProvider` now takes an asynchronous callback
The `spellCheck` callback is now asynchronous, and `autoCorrectWord` parameter has been removed.
```js
// Deprecated
webFrame.setSpellCheckProvider('en-US', true, {
spellCheck: (text) => {
return !spellchecker.isMisspelled(text)
}
})
// Replace with
webFrame.setSpellCheckProvider('en-US', {
spellCheck: (words, callback) => {
callback(words.filter(text => spellchecker.isMisspelled(text)))
}
})
```
### API Changed: `webContents.getZoomLevel` and `webContents.getZoomFactor` are now synchronous
`webContents.getZoomLevel` and `webContents.getZoomFactor` no longer take callback parameters,
instead directly returning their number values.
```js
// Deprecated
webContents.getZoomLevel((level) => {
console.log(level)
})
// Replace with
const level = webContents.getZoomLevel()
console.log(level)
```
```js
// Deprecated
webContents.getZoomFactor((factor) => {
console.log(factor)
})
// Replace with
const factor = webContents.getZoomFactor()
console.log(factor)
```
## Planned Breaking API Changes (4.0)
The following list includes the breaking API changes made in Electron 4.0.
### `app.makeSingleInstance`
```js
// Deprecated
app.makeSingleInstance((argv, cwd) => {
/* ... */
})
// Replace with
app.requestSingleInstanceLock()
app.on('second-instance', (event, argv, cwd) => {
/* ... */
})
```
### `app.releaseSingleInstance`
```js
// Deprecated
app.releaseSingleInstance()
// Replace with
app.releaseSingleInstanceLock()
```
### `app.getGPUInfo`
```js
app.getGPUInfo('complete')
// Now behaves the same with `basic` on macOS
app.getGPUInfo('basic')
```
### `win_delay_load_hook`
When building native modules for windows, the `win_delay_load_hook` variable in
the module's `binding.gyp` must be true (which is the default). If this hook is
not present, then the native module will fail to load on Windows, with an error
message like `Cannot find module`. See the [native module
guide](/docs/tutorial/using-native-node-modules.md) for more.

```
### Duplicate ARM Assets
Each Electron release includes two identical ARM builds with slightly different
filenames, like `electron-v1.7.3-linux-arm.zip` and
`electron-v1.7.3-linux-armv7l.zip`. The asset with the `v7l` prefix was added
to clarify to users which ARM version it supports, and to disambiguate it from
future armv6l and arm64 assets that may be produced.
The file _without the prefix_ is still being published to avoid breaking any
setups that may be consuming it. Starting at 2.0, the unprefixed file will
no longer be published.
For details, see
[6986](https://github.com/electron/electron/pull/6986)
and
[7189](https://github.com/electron/electron/pull/7189).

# BrowserWindow
> Create and control browser windows.
Process: [Main](../glossary.md#main-process)
```javascript
// In the main process.
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
// Load a remote URL
win.loadURL('https://github.com')
// Or load a local HTML file
win.loadFile('index.html')
```
## Window customization
The `BrowserWindow` class exposes various ways to modify the look and behavior of
your app's windows. For more details, see the [Window Customization](../tutorial/window-customization.md)
tutorial.
## Showing the window gracefully
When loading a page in the window directly, users may see the page load incrementally,
which is not a good experience for a native app. To make the window display
without a visual flash, there are two solutions for different situations.
### Using the `ready-to-show` event
While loading the page, the `ready-to-show` event will be emitted when the renderer
process has rendered the page for the first time if the window has not been shown yet. Showing
the window after this event will have no visual flash:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ show: false })
win.once('ready-to-show', () => {
win.show()
})
```
This event is usually emitted after the `did-finish-load` event, but for
pages with many remote resources, it may be emitted before the `did-finish-load`
event.
Please note that using this event implies that the renderer will be considered "visible" and
paint even though `show` is false. This event will never fire if you use `paintWhenInitiallyHidden: false`
### Setting the `backgroundColor` property
For a complex app, the `ready-to-show` event could be emitted too late, making
the app feel slow. In this case, it is recommended to show the window
immediately, and use a `backgroundColor` close to your app's background:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ backgroundColor: '#2e2c29' })
win.loadURL('https://github.com')
```
Note that even for apps that use `ready-to-show` event, it is still recommended
to set `backgroundColor` to make the app feel more native.
Some examples of valid `backgroundColor` values include:
```js
const win = new BrowserWindow()
win.setBackgroundColor('hsl(230, 100%, 50%)')
win.setBackgroundColor('rgb(255, 145, 145)')
win.setBackgroundColor('#ff00a3')
win.setBackgroundColor('blueviolet')
```
For more information about these color types see valid options in [win.setBackgroundColor](browser-window.md#winsetbackgroundcolorbackgroundcolor).
## Parent and child windows
By using `parent` option, you can create child windows:
```javascript
const { BrowserWindow } = require('electron')
const top = new BrowserWindow()
const child = new BrowserWindow({ parent: top })
child.show()
top.show()
```
The `child` window will always show on top of the `top` window.
## Modal windows
A modal window is a child window that disables parent window, to create a modal
window, you have to set both `parent` and `modal` options:
```javascript
const { BrowserWindow } = require('electron')
const child = new BrowserWindow({ parent: top, modal: true, show: false })
child.loadURL('https://github.com')
child.once('ready-to-show', () => {
child.show()
})
```
## Page visibility
The [Page Visibility API][page-visibility-api] works as follows:
* On all platforms, the visibility state tracks whether the window is
hidden/minimized or not.
* Additionally, on macOS, the visibility state also tracks the window
occlusion state. If the window is occluded (i.e. fully covered) by another
window, the visibility state will be `hidden`. On other platforms, the
visibility state will be `hidden` only when the window is minimized or
explicitly hidden with `win.hide()`.
* If a `BrowserWindow` is created with `show: false`, the initial visibility
state will be `visible` despite the window actually being hidden.
* If `backgroundThrottling` is disabled, the visibility state will remain
`visible` even if the window is minimized, occluded, or hidden.
It is recommended that you pause expensive operations when the visibility
state is `hidden` in order to minimize power consumption.
## Platform notices
* On macOS modal windows will be displayed as sheets attached to the parent window.
* On macOS the child windows will keep the relative position to parent window
when parent window moves, while on Windows and Linux child windows will not
move.
* On Linux the type of modal windows will be changed to `dialog`.
* On Linux many desktop environments do not support hiding a modal window.
## Class: BrowserWindow
> Create and control browser windows.
Process: [Main](../glossary.md#main-process)
`BrowserWindow` is an [EventEmitter][event-emitter].
It creates a new `BrowserWindow` with native properties as set by the `options`.
### `new BrowserWindow([options])`
* `options` Object (optional)
* `width` Integer (optional) - Window's width in pixels. Default is `800`.
* `height` Integer (optional) - Window's height in pixels. Default is `600`.
* `x` Integer (optional) - (**required** if y is used) Window's left offset from screen.
Default is to center the window.
* `y` Integer (optional) - (**required** if x is used) Window's top offset from screen.
Default is to center the window.
* `useContentSize` boolean (optional) - The `width` and `height` would be used as web
page's size, which means the actual window's size will include window
frame's size and be slightly larger. Default is `false`.
* `center` boolean (optional) - Show window in the center of the screen. Default is `false`.
* `minWidth` Integer (optional) - Window's minimum width. Default is `0`.
* `minHeight` Integer (optional) - Window's minimum height. Default is `0`.
* `maxWidth` Integer (optional) - Window's maximum width. Default is no limit.
* `maxHeight` Integer (optional) - Window's maximum height. Default is no limit.
* `resizable` boolean (optional) - Whether window is resizable. Default is `true`.
* `movable` boolean (optional) - Whether window is movable. This is not implemented
on Linux. Default is `true`.
* `minimizable` boolean (optional) - Whether window is minimizable. This is not
implemented on Linux. Default is `true`.
* `maximizable` boolean (optional) - Whether window is maximizable. This is not
implemented on Linux. Default is `true`.
* `closable` boolean (optional) - Whether window is closable. This is not implemented
on Linux. Default is `true`.
* `focusable` boolean (optional) - Whether the window can be focused. Default is
`true`. On Windows setting `focusable: false` also implies setting
`skipTaskbar: true`. On Linux setting `focusable: false` makes the window
stop interacting with wm, so the window will always stay on top in all
workspaces.
* `alwaysOnTop` boolean (optional) - Whether the window should always stay on top of
other windows. Default is `false`.
* `fullscreen` boolean (optional) - Whether the window should show in fullscreen. When
explicitly set to `false` the fullscreen button will be hidden or disabled
on macOS. Default is `false`.
* `fullscreenable` boolean (optional) - Whether the window can be put into fullscreen
mode. On macOS, also whether the maximize/zoom button should toggle full
screen mode or maximize window. Default is `true`.
* `simpleFullscreen` boolean (optional) - Use pre-Lion fullscreen on macOS. Default is `false`.
* `skipTaskbar` boolean (optional) - Whether to show the window in taskbar. Default is
`false`.
* `kiosk` boolean (optional) - Whether the window is in kiosk mode. Default is `false`.
* `title` string (optional) - Default window title. Default is `"Electron"`. If the HTML tag `<title>` is defined in the HTML file loaded by `loadURL()`, this property will be ignored.
* `icon` ([NativeImage](native-image.md) | string) (optional) - The window icon. On Windows it is
recommended to use `ICO` icons to get best visual effects, you can also
leave it undefined so the executable's icon will be used.
* `show` boolean (optional) - Whether window should be shown when created. Default is
`true`.
* `paintWhenInitiallyHidden` boolean (optional) - Whether the renderer should be active when `show` is `false` and it has just been created. In order for `document.visibilityState` to work correctly on first load with `show: false` you should set this to `false`. Setting this to `false` will cause the `ready-to-show` event to not fire. Default is `true`.
* `frame` boolean (optional) - Specify `false` to create a
[frameless window](../tutorial/window-customization.md#create-frameless-windows). Default is `true`.
* `parent` BrowserWindow (optional) - Specify parent window. Default is `null`.
* `modal` boolean (optional) - Whether this is a modal window. This only works when the
window is a child window. Default is `false`.
* `acceptFirstMouse` boolean (optional) - Whether clicking an inactive window will also
click through to the web contents. Default is `false` on macOS. This option is not
configurable on other platforms.
* `disableAutoHideCursor` boolean (optional) - Whether to hide cursor when typing.
Default is `false`.
* `autoHideMenuBar` boolean (optional) - Auto hide the menu bar unless the `Alt`
key is pressed. Default is `false`.
* `enableLargerThanScreen` boolean (optional) - Enable the window to be resized larger
than screen. Only relevant for macOS, as other OSes allow
larger-than-screen windows by default. Default is `false`.
* `backgroundColor` string (optional) - The window's background color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. Alpha in #AARRGGBB format is supported if `transparent` is set to `true`. Default is `#FFF` (white). See [win.setBackgroundColor](browser-window.md#winsetbackgroundcolorbackgroundcolor) for more information.
* `hasShadow` boolean (optional) - Whether window should have a shadow. Default is `true`.
* `opacity` number (optional) - Set the initial opacity of the window, between 0.0 (fully
transparent) and 1.0 (fully opaque). This is only implemented on Windows and macOS.
* `darkTheme` boolean (optional) - Forces using dark theme for the window, only works on
some GTK+3 desktop environments. Default is `false`.
* `transparent` boolean (optional) - Makes the window [transparent](../tutorial/window-customization.md#create-transparent-windows).
Default is `false`. On Windows, does not work unless the window is frameless.
* `type` string (optional) - The type of window, default is normal window. See more about
this below.
* `visualEffectState` string (optional) - Specify how the material appearance should reflect window activity state on macOS. Must be used with the `vibrancy` property. Possible values are:
* `followWindow` - The backdrop should automatically appear active when the window is active, and inactive when it is not. This is the default.
* `active` - The backdrop should always appear active.
* `inactive` - The backdrop should always appear inactive.
* `titleBarStyle` string (optional) _macOS_ _Windows_ - The style of window title bar.
Default is `default`. Possible values are:
* `default` - Results in the standard title bar for macOS or Windows respectively.
* `hidden` - Results in a hidden title bar and a full size content window. On macOS, the window still has the standard window controls (“traffic lights”) in the top left. On Windows, when combined with `titleBarOverlay: true` it will activate the Window Controls Overlay (see `titleBarOverlay` for more information), otherwise no window controls will be shown.
* `hiddenInset` - Only on macOS, results in a hidden title bar with an alternative look
where the traffic light buttons are slightly more inset from the window edge.
* `customButtonsOnHover` - Only on macOS, results in a hidden title bar and a full size
content window, the traffic light buttons will display when being hovered
over in the top left of the window. **Note:** This option is currently
experimental.
* `trafficLightPosition` [Point](structures/point.md) (optional) - Set a
custom position for the traffic light buttons in frameless windows.
* `roundedCorners` boolean (optional) - Whether frameless window should have
rounded corners on macOS. Default is `true`.
* `fullscreenWindowTitle` boolean (optional) _Deprecated_ - Shows the title in
the title bar in full screen mode on macOS for `hiddenInset` titleBarStyle.
Default is `false`.
* `thickFrame` boolean (optional) - Use `WS_THICKFRAME` style for frameless windows on
Windows, which adds standard window frame. Setting it to `false` will remove
window shadow and window animations. Default is `true`.
* `vibrancy` string (optional) - Add a type of vibrancy effect to the window, only on
macOS. Can be `appearance-based`, `light`, `dark`, `titlebar`, `selection`,
`menu`, `popover`, `sidebar`, `medium-light`, `ultra-dark`, `header`, `sheet`, `window`, `hud`, `fullscreen-ui`, `tooltip`, `content`, `under-window`, or `under-page`. Please note that `appearance-based`, `light`, `dark`, `medium-light`, and `ultra-dark` are deprecated and have been removed in macOS Catalina (10.15).
* `zoomToPageWidth` boolean (optional) - Controls the behavior on macOS when
option-clicking the green stoplight button on the toolbar or by clicking the
Window > Zoom menu item. If `true`, the window will grow to the preferred
width of the web page when zoomed, `false` will cause it to zoom to the
width of the screen. This will also affect the behavior when calling
`maximize()` directly. Default is `false`.
* `tabbingIdentifier` string (optional) - Tab group name, allows opening the
window as a native tab on macOS 10.12+. Windows with the same tabbing
identifier will be grouped together. This also adds a native new tab button
to your window's tab bar and allows your `app` and window to receive the
`new-window-for-tab` event.
* `webPreferences` Object (optional) - Settings of web page's features.
* `devTools` boolean (optional) - Whether to enable DevTools. If it is set to `false`, can not use `BrowserWindow.webContents.openDevTools()` to open DevTools. Default is `true`.
* `nodeIntegration` boolean (optional) - Whether node integration is enabled.
Default is `false`.
* `nodeIntegrationInWorker` boolean (optional) - Whether node integration is
enabled in web workers. Default is `false`. More about this can be found
in [Multithreading](../tutorial/multithreading.md).
* `nodeIntegrationInSubFrames` boolean (optional) - Experimental option for
enabling Node.js support in sub-frames such as iframes and child windows. All your preloads will load for
every iframe, you can use `process.isMainFrame` to determine if you are
in the main frame or not.
* `preload` string (optional) - Specifies a script that will be loaded before other
scripts run in the page. This script will always have access to node APIs
no matter whether node integration is turned on or off. The value should
be the absolute file path to the script.
When node integration is turned off, the preload script can reintroduce
Node global symbols back to the global scope. See example
[here](context-bridge.md#exposing-node-global-symbols).
* `sandbox` boolean (optional) - If set, this will sandbox the renderer
associated with the window, making it compatible with the Chromium
OS-level sandbox and disabling the Node.js engine. This is not the same as
the `nodeIntegration` option and the APIs available to the preload script
are more limited. Read more about the option [here](../tutorial/sandbox.md).
* `session` [Session](session.md#class-session) (optional) - Sets the session used by the
page. Instead of passing the Session object directly, you can also choose to
use the `partition` option instead, which accepts a partition string. When
both `session` and `partition` are provided, `session` will be preferred.
Default is the default session.
* `partition` string (optional) - Sets the session used by the page according to the
session's partition string. If `partition` starts with `persist:`, the page
will use a persistent session available to all pages in the app with the
same `partition`. If there is no `persist:` prefix, the page will use an
in-memory session. By assigning the same `partition`, multiple pages can share
the same session. Default is the default session.
* `zoomFactor` number (optional) - The default zoom factor of the page, `3.0` represents
`300%`. Default is `1.0`.
* `javascript` boolean (optional) - Enables JavaScript support. Default is `true`.
* `webSecurity` boolean (optional) - When `false`, it will disable the
same-origin policy (usually using testing websites by people), and set
`allowRunningInsecureContent` to `true` if this options has not been set
by user. Default is `true`.
* `allowRunningInsecureContent` boolean (optional) - Allow an https page to run
JavaScript, CSS or plugins from http URLs. Default is `false`.
* `images` boolean (optional) - Enables image support. Default is `true`.
* `imageAnimationPolicy` string (optional) - Specifies how to run image animations (E.g. GIFs). Can be `animate`, `animateOnce` or `noAnimation`. Default is `animate`.
* `textAreasAreResizable` boolean (optional) - Make TextArea elements resizable. Default
is `true`.
* `webgl` boolean (optional) - Enables WebGL support. Default is `true`.
* `plugins` boolean (optional) - Whether plugins should be enabled. Default is `false`.
* `experimentalFeatures` boolean (optional) - Enables Chromium's experimental features.
Default is `false`.
* `scrollBounce` boolean (optional) - Enables scroll bounce (rubber banding) effect on
macOS. Default is `false`.
* `enableBlinkFeatures` string (optional) - A list of feature strings separated by `,`, like
`CSSVariables,KeyboardEventKey` to enable. The full list of supported feature
strings can be found in the [RuntimeEnabledFeatures.json5][runtime-enabled-features]
file.
* `disableBlinkFeatures` string (optional) - A list of feature strings separated by `,`,
like `CSSVariables,KeyboardEventKey` to disable. The full list of supported
feature strings can be found in the
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
* `defaultFontFamily` Object (optional) - Sets the default font for the font-family.
* `standard` string (optional) - Defaults to `Times New Roman`.
* `serif` string (optional) - Defaults to `Times New Roman`.
* `sansSerif` string (optional) - Defaults to `Arial`.
* `monospace` string (optional) - Defaults to `Courier New`.
* `cursive` string (optional) - Defaults to `Script`.
* `fantasy` string (optional) - Defaults to `Impact`.
* `defaultFontSize` Integer (optional) - Defaults to `16`.
* `defaultMonospaceFontSize` Integer (optional) - Defaults to `13`.
* `minimumFontSize` Integer (optional) - Defaults to `0`.
* `defaultEncoding` string (optional) - Defaults to `ISO-8859-1`.
* `backgroundThrottling` boolean (optional) - Whether to throttle animations and timers
when the page becomes background. This also affects the
[Page Visibility API](#page-visibility). Defaults to `true`.
* `offscreen` boolean (optional) - Whether to enable offscreen rendering for the browser
window. Defaults to `false`. See the
[offscreen rendering tutorial](../tutorial/offscreen-rendering.md) for
more details.
* `contextIsolation` boolean (optional) - Whether to run Electron APIs and
the specified `preload` script in a separate JavaScript context. Defaults
to `true`. The context that the `preload` script runs in will only have
access to its own dedicated `document` and `window` globals, as well as
its own set of JavaScript builtins (`Array`, `Object`, `JSON`, etc.),
which are all invisible to the loaded content. The Electron API will only
be available in the `preload` script and not the loaded page. This option
should be used when loading potentially untrusted remote content to ensure
the loaded content cannot tamper with the `preload` script and any
Electron APIs being used. This option uses the same technique used by
[Chrome Content Scripts][chrome-content-scripts]. You can access this
context in the dev tools by selecting the 'Electron Isolated Context'
entry in the combo box at the top of the Console tab.
* `webviewTag` boolean (optional) - Whether to enable the [`<webview>` tag](webview-tag.md).
Defaults to `false`. **Note:** The
`preload` script configured for the `<webview>` will have node integration
enabled when it is executed so you should ensure remote/untrusted content
is not able to create a `<webview>` tag with a possibly malicious `preload`
script. You can use the `will-attach-webview` event on [webContents](web-contents.md)
to strip away the `preload` script and to validate or alter the
`<webview>`'s initial settings.
* `additionalArguments` string[] (optional) - A list of strings that will be appended
to `process.argv` in the renderer process of this app. Useful for passing small
bits of data down to renderer process preload scripts.
* `safeDialogs` boolean (optional) - Whether to enable browser style
consecutive dialog protection. Default is `false`.
* `safeDialogsMessage` string (optional) - The message to display when
consecutive dialog protection is triggered. If not defined the default
message would be used, note that currently the default message is in
English and not localized.
* `disableDialogs` boolean (optional) - Whether to disable dialogs
completely. Overrides `safeDialogs`. Default is `false`.
* `navigateOnDragDrop` boolean (optional) - Whether dragging and dropping a
file or link onto the page causes a navigation. Default is `false`.
* `autoplayPolicy` string (optional) - Autoplay policy to apply to
content in the window, can be `no-user-gesture-required`,
`user-gesture-required`, `document-user-activation-required`. Defaults to
`no-user-gesture-required`.
* `disableHtmlFullscreenWindowResize` boolean (optional) - Whether to
prevent the window from resizing when entering HTML Fullscreen. Default
is `false`.
* `accessibleTitle` string (optional) - An alternative title string provided only
to accessibility tools such as screen readers. This string is not directly
visible to users.
* `spellcheck` boolean (optional) - Whether to enable the builtin spellchecker.
Default is `true`.
* `enableWebSQL` boolean (optional) - Whether to enable the [WebSQL api](https://www.w3.org/TR/webdatabase/).
Default is `true`.
* `v8CacheOptions` string (optional) - Enforces the v8 code caching policy
used by blink. Accepted values are
* `none` - Disables code caching
* `code` - Heuristic based code caching
* `bypassHeatCheck` - Bypass code caching heuristics but with lazy compilation
* `bypassHeatCheckAndEagerCompile` - Same as above except compilation is eager.
Default policy is `code`.
* `enablePreferredSizeMode` boolean (optional) - Whether to enable
preferred size mode. The preferred size is the minimum size needed to
contain the layout of the document—without requiring scrolling. Enabling
this will cause the `preferred-size-changed` event to be emitted on the
`WebContents` when the preferred size changes. Default is `false`.
* `titleBarOverlay` Object | Boolean (optional) - When using a frameless window in conjunction with `win.setWindowButtonVisibility(true)` on macOS or using a `titleBarStyle` so that the standard window controls ("traffic lights" on macOS) are visible, this property enables the Window Controls Overlay [JavaScript APIs][overlay-javascript-apis] and [CSS Environment Variables][overlay-css-env-vars]. Specifying `true` will result in an overlay with default system colors. Default is `false`.
* `color` String (optional) _Windows_ - The CSS color of the Window Controls Overlay when enabled. Default is the system color.
* `symbolColor` String (optional) _Windows_ - The CSS color of the symbols on the Window Controls Overlay when enabled. Default is the system color.
* `height` Integer (optional) _macOS_ _Windows_ - The height of the title bar and Window Controls Overlay in pixels. Default is system height.
When setting minimum or maximum window size with `minWidth`/`maxWidth`/
`minHeight`/`maxHeight`, it only constrains the users. It won't prevent you from
passing a size that does not follow size constraints to `setBounds`/`setSize` or
to the constructor of `BrowserWindow`.
The possible values and behaviors of the `type` option are platform dependent.
Possible values are:
* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
`notification`.
* On macOS, possible types are `desktop`, `textured`.
* The `textured` type adds metal gradient appearance
(`NSTexturedBackgroundWindowMask`).
* The `desktop` type places the window at the desktop background window level
(`kCGDesktopWindowLevel - 1`). Note that desktop window will not receive
focus, keyboard or mouse events, but you can use `globalShortcut` to receive
input sparingly.
* On Windows, possible type is `toolbar`.
### Instance Events
Objects created with `new BrowserWindow` emit the following events:
**Note:** Some events are only available on specific operating systems and are
labeled as such.
#### Event: 'page-title-updated'
Returns:
* `event` Event
* `title` string
* `explicitSet` boolean
Emitted when the document changed its title, calling `event.preventDefault()`
will prevent the native window's title from changing.
`explicitSet` is false when title is synthesized from file URL.
#### Event: 'close'
Returns:
* `event` Event
Emitted when the window is going to be closed. It's emitted before the
`beforeunload` and `unload` event of the DOM. Calling `event.preventDefault()`
will cancel the close.
Usually you would want to use the `beforeunload` handler to decide whether the
window should be closed, which will also be called when the window is
reloaded. In Electron, returning any value other than `undefined` would cancel the
close. For example:
```javascript
window.onbeforeunload = (e) => {
console.log('I do not want to be closed')
// Unlike usual browsers that a message box will be prompted to users, returning
// a non-void value will silently cancel the close.
// It is recommended to use the dialog API to let the user confirm closing the
// application.
e.returnValue = false // equivalent to `return false` but not recommended
}
```
_**Note**: There is a subtle difference between the behaviors of `window.onbeforeunload = handler` and `window.addEventListener('beforeunload', handler)`. It is recommended to always set the `event.returnValue` explicitly, instead of only returning a value, as the former works more consistently within Electron._
#### Event: 'closed'
Emitted when the window is closed. After you have received this event you should
remove the reference to the window and avoid using it any more.
#### Event: 'session-end' _Windows_
Emitted when window session is going to end due to force shutdown or machine restart
or session log off.
#### Event: 'unresponsive'
Emitted when the web page becomes unresponsive.
#### Event: 'responsive'
Emitted when the unresponsive web page becomes responsive again.
#### Event: 'blur'
Emitted when the window loses focus.
#### Event: 'focus'
Emitted when the window gains focus.
#### Event: 'show'
Emitted when the window is shown.
#### Event: 'hide'
Emitted when the window is hidden.
#### Event: 'ready-to-show'
Emitted when the web page has been rendered (while not being shown) and window can be displayed without
a visual flash.
Please note that using this event implies that the renderer will be considered "visible" and
paint even though `show` is false. This event will never fire if you use `paintWhenInitiallyHidden: false`
#### Event: 'maximize'
Emitted when window is maximized.
#### Event: 'unmaximize'
Emitted when the window exits from a maximized state.
#### Event: 'minimize'
Emitted when the window is minimized.
#### Event: 'restore'
Emitted when the window is restored from a minimized state.
#### Event: 'will-resize' _macOS_ _Windows_
Returns:
* `event` Event
* `newBounds` [Rectangle](structures/rectangle.md) - Size the window is being resized to.
* `details` Object
* `edge` (string) - The edge of the window being dragged for resizing. Can be `bottom`, `left`, `right`, `top-left`, `top-right`, `bottom-left` or `bottom-right`.
Emitted before the window is resized. Calling `event.preventDefault()` will prevent the window from being resized.
Note that this is only emitted when the window is being resized manually. Resizing the window with `setBounds`/`setSize` will not emit this event.
The possible values and behaviors of the `edge` option are platform dependent. Possible values are:
* On Windows, possible values are `bottom`, `top`, `left`, `right`, `top-left`, `top-right`, `bottom-left`, `bottom-right`.
* On macOS, possible values are `bottom` and `right`.
* The value `bottom` is used to denote vertical resizing.
* The value `right` is used to denote horizontal resizing.
#### Event: 'resize'
Emitted after the window has been resized.
#### Event: 'resized' _macOS_ _Windows_
Emitted once when the window has finished being resized.
This is usually emitted when the window has been resized manually. On macOS, resizing the window with `setBounds`/`setSize` and setting the `animate` parameter to `true` will also emit this event once resizing has finished.
#### Event: 'will-move' _macOS_ _Windows_
Returns:
* `event` Event
* `newBounds` [Rectangle](structures/rectangle.md) - Location the window is being moved to.
Emitted before the window is moved. On Windows, calling `event.preventDefault()` will prevent the window from being moved.
Note that this is only emitted when the window is being moved manually. Moving the window with `setPosition`/`setBounds`/`center` will not emit this event.
#### Event: 'move'
Emitted when the window is being moved to a new position.
#### Event: 'moved' _macOS_ _Windows_
Emitted once when the window is moved to a new position.
__Note__: On macOS this event is an alias of `move`.
#### Event: 'enter-full-screen'
Emitted when the window enters a full-screen state.
#### Event: 'leave-full-screen'
Emitted when the window leaves a full-screen state.
#### Event: 'enter-html-full-screen'
Emitted when the window enters a full-screen state triggered by HTML API.
#### Event: 'leave-html-full-screen'
Emitted when the window leaves a full-screen state triggered by HTML API.
#### Event: 'always-on-top-changed'
Returns:
* `event` Event
* `isAlwaysOnTop` boolean
Emitted when the window is set or unset to show always on top of other windows.
#### Event: 'app-command' _Windows_ _Linux_
Returns:
* `event` Event
* `command` string
Emitted when an [App Command](https://msdn.microsoft.com/en-us/library/windows/desktop/ms646275(v=vs.85).aspx)
is invoked. These are typically related to keyboard media keys or browser
commands, as well as the "Back" button built into some mice on Windows.
Commands are lowercased, underscores are replaced with hyphens, and the
`APPCOMMAND_` prefix is stripped off.
e.g. `APPCOMMAND_BROWSER_BACKWARD` is emitted as `browser-backward`.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.on('app-command', (e, cmd) => {
// Navigate the window back when the user hits their mouse back button
if (cmd === 'browser-backward' && win.webContents.canGoBack()) {
win.webContents.goBack()
}
})
```
The following app commands are explicitly supported on Linux:
* `browser-backward`
* `browser-forward`
#### Event: 'scroll-touch-begin' _macOS_
Emitted when scroll wheel event phase has begun.
#### Event: 'scroll-touch-end' _macOS_
Emitted when scroll wheel event phase has ended.
#### Event: 'scroll-touch-edge' _macOS_
Emitted when scroll wheel event phase filed upon reaching the edge of element.
#### Event: 'swipe' _macOS_
Returns:
* `event` Event
* `direction` string
Emitted on 3-finger swipe. Possible directions are `up`, `right`, `down`, `left`.
The method underlying this event is built to handle older macOS-style trackpad swiping,
where the content on the screen doesn't move with the swipe. Most macOS trackpads are not
configured to allow this kind of swiping anymore, so in order for it to emit properly the
'Swipe between pages' preference in `System Preferences > Trackpad > More Gestures` must be
set to 'Swipe with two or three fingers'.
#### Event: 'rotate-gesture' _macOS_
Returns:
* `event` Event
* `rotation` Float
Emitted on trackpad rotation gesture. Continually emitted until rotation gesture is
ended. The `rotation` value on each emission is the angle in degrees rotated since
the last emission. The last emitted event upon a rotation gesture will always be of
value `0`. Counter-clockwise rotation values are positive, while clockwise ones are
negative.
#### Event: 'sheet-begin' _macOS_
Emitted when the window opens a sheet.
#### Event: 'sheet-end' _macOS_
Emitted when the window has closed a sheet.
#### Event: 'new-window-for-tab' _macOS_
Emitted when the native new tab button is clicked.
#### Event: 'system-context-menu' _Windows_
Returns:
* `event` Event
* `point` [Point](structures/point.md) - The screen coordinates the context menu was triggered at
Emitted when the system context menu is triggered on the window, this is
normally only triggered when the user right clicks on the non-client area
of your window. This is the window titlebar or any area you have declared
as `-webkit-app-region: drag` in a frameless window.
Calling `event.preventDefault()` will prevent the menu from being displayed.
### Static Methods

const menu = Menu.buildFromTemplate(template)
Menu.setApplicationMenu(menu)
```
#### `win.accessibleTitle`
A `string` property that defines an alternative title provided only to
accessibility tools such as screen readers. This string is not directly
visible to users.
### Instance Methods
Objects created with `new BrowserWindow` have the following instance methods:
**Note:** Some methods are only available on specific operating systems and are
labeled as such.
#### `win.destroy()`
Force closing the window, the `unload` and `beforeunload` event won't be emitted
for the web page, and `close` event will also not be emitted
for this window, but it guarantees the `closed` event will be emitted.
#### `win.close()`
Try to close the window. This has the same effect as a user manually clicking
the close button of the window. The web page may cancel the close though. See
the [close event](#event-close).
#### `win.focus()`
Focuses on the window.
#### `win.blur()`
Removes focus from the window.
#### `win.isFocused()`
Returns `boolean` - Whether the window is focused.
#### `win.isDestroyed()`
Returns `boolean` - Whether the window is destroyed.
#### `win.show()`
Shows and gives focus to the window.
#### `win.showInactive()`
Shows the window but doesn't focus on it.
#### `win.hide()`
Hides the window.
#### `win.isVisible()`
Returns `boolean` - Whether the window is visible to the user.
#### `win.isModal()`
Returns `boolean` - Whether current window is a modal window.
#### `win.maximize()`
Maximizes the window. This will also show (but not focus) the window if it
isn't being displayed already.
#### `win.unmaximize()`
Unmaximizes the window.
#### `win.isMaximized()`
Returns `boolean` - Whether the window is maximized.
#### `win.minimize()`
Minimizes the window. On some platforms the minimized window will be shown in
the Dock.
#### `win.restore()`
Restores the window from minimized state to its previous state.
#### `win.isMinimized()`
Returns `boolean` - Whether the window is minimized.
#### `win.setFullScreen(flag)`
* `flag` boolean
Sets whether the window should be in fullscreen mode.
#### `win.isFullScreen()`
Returns `boolean` - Whether the window is in fullscreen mode.
#### `win.setSimpleFullScreen(flag)` _macOS_
* `flag` boolean
Enters or leaves simple fullscreen mode.
Simple fullscreen mode emulates the native fullscreen behavior found in versions of macOS prior to Lion (10.7).
#### `win.isSimpleFullScreen()` _macOS_
Returns `boolean` - Whether the window is in simple (pre-Lion) fullscreen mode.
#### `win.isNormal()`
Returns `boolean` - Whether the window is in normal state (not maximized, not minimized, not in fullscreen mode).
#### `win.setAspectRatio(aspectRatio[, extraSize])`
* `aspectRatio` Float - The aspect ratio to maintain for some portion of the
content view.
* `extraSize` [Size](structures/size.md) (optional) _macOS_ - The extra size not to be included while
maintaining the aspect ratio.
This will make a window maintain an aspect ratio. The extra size allows a
developer to have space, specified in pixels, not included within the aspect
ratio calculations. This API already takes into account the difference between a
window's size and its content size.
Consider a normal window with an HD video player and associated controls.
Perhaps there are 15 pixels of controls on the left edge, 25 pixels of controls
on the right edge and 50 pixels of controls below the player. In order to
maintain a 16:9 aspect ratio (standard aspect ratio for HD @1920x1080) within
the player itself we would call this function with arguments of 16/9 and
{ width: 40, height: 50 }. The second argument doesn't care where the extra width and height
are within the content view--only that they exist. Sum any extra width and
height areas you have within the overall content view.
The aspect ratio is not respected when window is resized programmatically with
APIs like `win.setSize`.
#### `win.setBackgroundColor(backgroundColor)`
* `backgroundColor` string - Color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. The alpha channel is optional for the hex type.
Examples of valid `backgroundColor` values:
* Hex
* #fff (shorthand RGB)
* #ffff (shorthand ARGB)
* #ffffff (RGB)
* #ffffffff (ARGB)
* RGB
* rgb\(([\d]+),\s*([\d]+),\s*([\d]+)\)
* e.g. rgb(255, 255, 255)
* RGBA
* rgba\(([\d]+),\s*([\d]+),\s*([\d]+),\s*([\d.]+)\)
* e.g. rgba(255, 255, 255, 1.0)
* HSL
* hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)
* e.g. hsl(200, 20%, 50%)
* HSLA
* hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)
* e.g. hsla(200, 20%, 50%, 0.5)
* Color name
* Options are listed in [SkParseColor.cpp](https://source.chromium.org/chromium/chromium/src/+/main:third_party/skia/src/utils/SkParseColor.cpp;l=11-152;drc=eea4bf52cb0d55e2a39c828b017c80a5ee054148)
* Similar to CSS Color Module Level 3 keywords, but case-sensitive.
* e.g. `blueviolet` or `red`
Sets the background color of the window. See [Setting `backgroundColor`](#setting-the-backgroundcolor-property).
#### `win.previewFile(path[, displayName])` _macOS_
* `path` string - The absolute path to the file to preview with QuickLook. This
is important as Quick Look uses the file name and file extension on the path
to determine the content type of the file to open.
* `displayName` string (optional) - The name of the file to display on the
Quick Look modal view. This is purely visual and does not affect the content
type of the file. Defaults to `path`.
Uses [Quick Look][quick-look] to preview a file at a given path.
#### `win.closeFilePreview()` _macOS_
Closes the currently open [Quick Look][quick-look] panel.
#### `win.setBounds(bounds[, animate])`
* `bounds` Partial<[Rectangle](structures/rectangle.md)>
* `animate` boolean (optional) _macOS_
Resizes and moves the window to the supplied bounds. Any properties that are not supplied will default to their current values.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
// set all bounds properties
win.setBounds({ x: 440, y: 225, width: 800, height: 600 })
// set a single bounds property
win.setBounds({ width: 100 })
// { x: 440, y: 225, width: 100, height: 600 }
console.log(win.getBounds())
```
#### `win.getBounds()`
Returns [`Rectangle`](structures/rectangle.md) - The `bounds` of the window as `Object`.
#### `win.getBackgroundColor()`
Returns `string` - Gets the background color of the window in Hex (`#RRGGBB`) format.
See [Setting `backgroundColor`](#setting-the-backgroundcolor-property).
**Note:** The alpha value is _not_ returned alongside the red, green, and blue values.
#### `win.setContentBounds(bounds[, animate])`
* `bounds` [Rectangle](structures/rectangle.md)
* `animate` boolean (optional) _macOS_
Resizes and moves the window's client area (e.g. the web page) to
the supplied bounds.
#### `win.getContentBounds()`
Returns [`Rectangle`](structures/rectangle.md) - The `bounds` of the window's client area as `Object`.
#### `win.getNormalBounds()`
Returns [`Rectangle`](structures/rectangle.md) - Contains the window bounds of the normal state
**Note:** whatever the current state of the window : maximized, minimized or in fullscreen, this function always returns the position and size of the window in normal state. In normal state, getBounds and getNormalBounds returns the same [`Rectangle`](structures/rectangle.md).
#### `win.setEnabled(enable)`
* `enable` boolean
Disable or enable the window.
#### `win.isEnabled()`
Returns `boolean` - whether the window is enabled.
#### `win.setSize(width, height[, animate])`
* `width` Integer
* `height` Integer
* `animate` boolean (optional) _macOS_
Resizes the window to `width` and `height`. If `width` or `height` are below any set minimum size constraints the window will snap to its minimum size.
#### `win.getSize()`
Returns `Integer[]` - Contains the window's width and height.
#### `win.setContentSize(width, height[, animate])`
* `width` Integer
* `height` Integer
* `animate` boolean (optional) _macOS_
Resizes the window's client area (e.g. the web page) to `width` and `height`.
#### `win.getContentSize()`

`floating`, `torn-off-menu`, `modal-panel`, `main-menu`, `status`,
`pop-up-menu`, `screen-saver`, and ~~`dock`~~ (Deprecated). The default is
`floating` when `flag` is true. The `level` is reset to `normal` when the
flag is false. Note that from `floating` to `status` included, the window is
placed below the Dock on macOS and below the taskbar on Windows. From
`pop-up-menu` to a higher it is shown above the Dock on macOS and above the
taskbar on Windows. See the [macOS docs][window-levels] for more details.

* `mediaSourceId` string - Window id in the format of DesktopCapturerSource's id. For example "window:1869:0".
Moves window above the source window in the sense of z-order. If the
`mediaSourceId` is not of type window or if the window does not exist then
this method throws an error.
#### `win.moveTop()`
Moves window to top(z-order) regardless of focus
#### `win.center()`
Moves window to the center of the screen.
#### `win.setPosition(x, y[, animate])`
* `x` Integer
* `y` Integer
* `animate` boolean (optional) _macOS_
Moves window to `x` and `y`.
#### `win.getPosition()`
Returns `Integer[]` - Contains the window's current position.
#### `win.setTitle(title)`
* `title` string
Changes the title of native window to `title`.
#### `win.getTitle()`
Returns `string` - The title of the native window.
**Note:** The title of the web page can be different from the title of the native
window.
#### `win.setSheetOffset(offsetY[, offsetX])` _macOS_
* `offsetY` Float
* `offsetX` Float (optional)
Changes the attachment point for sheets on macOS. By default, sheets are
attached just below the window frame, but you may want to display them beneath
a HTML-rendered toolbar. For example:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
const toolbarRect = document.getElementById('toolbar').getBoundingClientRect()
win.setSheetOffset(toolbarRect.height)
```
#### `win.flashFrame(flag)`
* `flag` boolean
Starts or stops flashing the window to attract user's attention.
#### `win.setSkipTaskbar(skip)`

#### `win.isKiosk()`
Returns `boolean` - Whether the window is in kiosk mode.
#### `win.isTabletMode()` _Windows_
Returns `boolean` - Whether the window is in Windows 10 tablet mode.
Since Windows 10 users can [use their PC as tablet](https://support.microsoft.com/en-us/help/17210/windows-10-use-your-pc-like-a-tablet),
under this mode apps can choose to optimize their UI for tablets, such as
enlarging the titlebar and hiding titlebar buttons.
This API returns whether the window is in tablet mode, and the `resize` event
can be be used to listen to changes to tablet mode.
#### `win.getMediaSourceId()`
Returns `string` - Window id in the format of DesktopCapturerSource's id. For example "window:1324:0".
More precisely the format is `window:id:other_id` where `id` is `HWND` on
Windows, `CGWindowID` (`uint64_t`) on macOS and `Window` (`unsigned long`) on
Linux. `other_id` is used to identify web contents (tabs) so within the same
top level window.
#### `win.getNativeWindowHandle()`
Returns `Buffer` - The platform-specific handle of the window.
The native type of the handle is `HWND` on Windows, `NSView*` on macOS, and
`Window` (`unsigned long`) on Linux.
#### `win.hookWindowMessage(message, callback)` _Windows_
* `message` Integer
* `callback` Function
* `wParam` any - The `wParam` provided to the WndProc
* `lParam` any - The `lParam` provided to the WndProc
Hooks a windows message. The `callback` is called when
the message is received in the WndProc.
#### `win.isWindowMessageHooked(message)` _Windows_
* `message` Integer

Unhooks all of the window messages.
#### `win.setRepresentedFilename(filename)` _macOS_
* `filename` string
Sets the pathname of the file the window represents, and the icon of the file
will show in window's title bar.
#### `win.getRepresentedFilename()` _macOS_
Returns `string` - The pathname of the file the window represents.
#### `win.setDocumentEdited(edited)` _macOS_
* `edited` boolean
Specifies whether the window’s document has been edited, and the icon in title
bar will become gray when set to `true`.
#### `win.isDocumentEdited()` _macOS_
Returns `boolean` - Whether the window's document has been edited.
#### `win.focusOnWebView()`
#### `win.blurWebView()`
#### `win.capturePage([rect])`
* `rect` [Rectangle](structures/rectangle.md) (optional) - The bounds to capture
Returns `Promise<NativeImage>` - Resolves with a [NativeImage](native-image.md)
Captures a snapshot of the page within `rect`. Omitting `rect` will capture the whole visible page. If the page is not visible, `rect` may be empty.
#### `win.loadURL(url[, options])`
* `url` string
* `options` Object (optional)
* `httpReferrer` (string | [Referrer](structures/referrer.md)) (optional) - An HTTP Referrer URL.
* `userAgent` string (optional) - A user agent originating the request.
* `extraHeaders` string (optional) - Extra headers separated by "\n"
* `postData` ([UploadRawData](structures/upload-raw-data.md) | [UploadFile](structures/upload-file.md))[] (optional)
* `baseURLForDataURL` string (optional) - Base URL (with trailing path separator) for files to be loaded by the data URL. This is needed only if the specified `url` is a data URL and needs to load other files.
Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Same as [`webContents.loadURL(url[, options])`](web-contents.md#contentsloadurlurl-options).
The `url` can be a remote address (e.g. `http://`) or a path to a local
HTML file using the `file://` protocol.
To ensure that file URLs are properly formatted, it is recommended to use
Node's [`url.format`](https://nodejs.org/api/url.html#url_url_format_urlobject)
method:
```javascript
const url = require('url').format({
protocol: 'file',
slashes: true,
pathname: require('path').join(__dirname, 'index.html')
})
win.loadURL(url)
```
You can load a URL using a `POST` request with URL-encoded data by doing
the following:
```javascript
win.loadURL('http://localhost:8000/post', {
postData: [{
type: 'rawData',
bytes: Buffer.from('hello=world')
}],
extraHeaders: 'Content-Type: application/x-www-form-urlencoded'
})
```
#### `win.loadFile(filePath[, options])`
* `filePath` string

* `query` Record<string, string> (optional) - Passed to `url.format()`.
* `search` string (optional) - Passed to `url.format()`.
* `hash` string (optional) - Passed to `url.format()`.
Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Same as `webContents.loadFile`, `filePath` should be a path to an HTML
file relative to the root of your application. See the `webContents` docs
for more information.
#### `win.reload()`
Same as `webContents.reload`.
#### `win.setMenu(menu)` _Linux_ _Windows_
* `menu` Menu | null
Sets the `menu` as the window's menu bar.
#### `win.removeMenu()` _Linux_ _Windows_
Remove the window's menu bar.
#### `win.setProgressBar(progress[, options])`
* `progress` Double
* `options` Object (optional)
* `mode` string _Windows_ - Mode for the progress bar. Can be `none`, `normal`, `indeterminate`, `error` or `paused`.
Sets progress value in progress bar. Valid range is [0, 1.0].
Remove progress bar when progress < 0;
Change to indeterminate mode when progress > 1.
On Linux platform, only supports Unity desktop environment, you need to specify
the `*.desktop` file name to `desktopName` field in `package.json`. By default,
it will assume `{app.name}.desktop`.
On Windows, a mode can be passed. Accepted values are `none`, `normal`,
`indeterminate`, `error`, and `paused`. If you call `setProgressBar` without a
mode set (but with a value within the valid range), `normal` will be assumed.
#### `win.setOverlayIcon(overlay, description)` _Windows_
* `overlay` [NativeImage](native-image.md) | null - the icon to display on the bottom
right corner of the taskbar icon. If this parameter is `null`, the overlay is
cleared
* `description` string - a description that will be provided to Accessibility
screen readers
Sets a 16 x 16 pixel overlay onto the current taskbar icon, usually used to
convey some sort of application status or to passively notify the user.
#### `win.setHasShadow(hasShadow)`
* `hasShadow` boolean
Sets whether the window should have a shadow.
#### `win.hasShadow()`
Returns `boolean` - Whether the window has a shadow.
#### `win.setOpacity(opacity)` _Windows_ _macOS_
* `opacity` number - between 0.0 (fully transparent) and 1.0 (fully opaque)
Sets the opacity of the window. On Linux, does nothing. Out of bound number
values are clamped to the [0, 1] range.
#### `win.getOpacity()`
Returns `number` - between 0.0 (fully transparent) and 1.0 (fully opaque). On
Linux, always returns 1.
#### `win.setShape(rects)` _Windows_ _Linux_ _Experimental_
* `rects` [Rectangle[]](structures/rectangle.md) - Sets a shape on the window.
Passing an empty list reverts the window to being rectangular.
Setting a window shape determines the area within the window where the system
permits drawing and user interaction. Outside of the given region, no pixels
will be drawn and no mouse events will be registered. Mouse events outside of
the region will not be received by that window, but will fall through to
whatever is behind the window.
#### `win.setThumbarButtons(buttons)` _Windows_
* `buttons` [ThumbarButton[]](structures/thumbar-button.md)
Returns `boolean` - Whether the buttons were added successfully
Add a thumbnail toolbar with a specified set of buttons to the thumbnail image
of a window in a taskbar button layout. Returns a `boolean` object indicates
whether the thumbnail has been added successfully.
The number of buttons in thumbnail toolbar should be no greater than 7 due to
the limited room. Once you setup the thumbnail toolbar, the toolbar cannot be
removed due to the platform's limitation. But you can call the API with an empty
array to clean the buttons.
The `buttons` is an array of `Button` objects:
* `Button` Object
* `icon` [NativeImage](native-image.md) - The icon showing in thumbnail
toolbar.
* `click` Function
* `tooltip` string (optional) - The text of the button's tooltip.
* `flags` string[] (optional) - Control specific states and behaviors of the
button. By default, it is `['enabled']`.
The `flags` is an array that can include following `string`s:
* `enabled` - The button is active and available to the user.
* `disabled` - The button is disabled. It is present, but has a visual state
indicating it will not respond to user action.
* `dismissonclick` - When the button is clicked, the thumbnail window closes
immediately.
* `nobackground` - Do not draw a button border, use only the image.
* `hidden` - The button is not shown to the user.
* `noninteractive` - The button is enabled but not interactive; no pressed
button state is drawn. This value is intended for instances where the button
is used in a notification.
#### `win.setThumbnailClip(region)` _Windows_
* `region` [Rectangle](structures/rectangle.md) - Region of the window
Sets the region of the window to show as the thumbnail image displayed when
hovering over the window in the taskbar. You can reset the thumbnail to be
the entire window by specifying an empty region:
`{ x: 0, y: 0, width: 0, height: 0 }`.
#### `win.setThumbnailToolTip(toolTip)` _Windows_
* `toolTip` string
Sets the toolTip that is displayed when hovering over the window thumbnail
in the taskbar.
#### `win.setAppDetails(options)` _Windows_
* `options` Object
* `appId` string (optional) - Window's [App User Model ID](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391569(v=vs.85).aspx).
It has to be set, otherwise the other options will have no effect.
* `appIconPath` string (optional) - Window's [Relaunch Icon](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391573(v=vs.85).aspx).
* `appIconIndex` Integer (optional) - Index of the icon in `appIconPath`.
Ignored when `appIconPath` is not set. Default is `0`.
* `relaunchCommand` string (optional) - Window's [Relaunch Command](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391571(v=vs.85).aspx).
* `relaunchDisplayName` string (optional) - Window's [Relaunch Display Name](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391572(v=vs.85).aspx).
Sets the properties for the window's taskbar button.
**Note:** `relaunchCommand` and `relaunchDisplayName` must always be set
together. If one of those properties is not set, then neither will be used.
#### `win.showDefinitionForSelection()` _macOS_
Same as `webContents.showDefinitionForSelection()`.
#### `win.setIcon(icon)` _Windows_ _Linux_
* `icon` [NativeImage](native-image.md) | string
Changes window icon.
#### `win.setWindowButtonVisibility(visible)` _macOS_
* `visible` boolean
Sets whether the window traffic light buttons should be visible.
#### `win.setAutoHideMenuBar(hide)`
* `hide` boolean
Sets whether the window menu bar should hide itself automatically. Once set the
menu bar will only show when users press the single `Alt` key.
If the menu bar is already visible, calling `setAutoHideMenuBar(true)` won't hide it immediately.
#### `win.isMenuBarAutoHide()`
Returns `boolean` - Whether menu bar automatically hides itself.
#### `win.setMenuBarVisibility(visible)` _Windows_ _Linux_
* `visible` boolean
Sets whether the menu bar should be visible. If the menu bar is auto-hide, users can still bring up the menu bar by pressing the single `Alt` key.
#### `win.isMenuBarVisible()`
Returns `boolean` - Whether the menu bar is visible.
#### `win.setVisibleOnAllWorkspaces(visible[, options])`
* `visible` boolean
* `options` Object (optional)
* `visibleOnFullScreen` boolean (optional) _macOS_ - Sets whether
the window should be visible above fullscreen windows.
* `skipTransformProcessType` boolean (optional) _macOS_ - Calling
setVisibleOnAllWorkspaces will by default transform the process
type between UIElementApplication and ForegroundApplication to
ensure the correct behavior. However, this will hide the window
and dock for a short time every time it is called. If your window
is already of type UIElementApplication, you can bypass this
transformation by passing true to skipTransformProcessType.
Sets whether the window should be visible on all workspaces.
**Note:** This API does nothing on Windows.
#### `win.isVisibleOnAllWorkspaces()`
Returns `boolean` - Whether the window is visible on all workspaces.
**Note:** This API always returns false on Windows.
#### `win.setIgnoreMouseEvents(ignore[, options])`
* `ignore` boolean
* `options` Object (optional)
* `forward` boolean (optional) _macOS_ _Windows_ - If true, forwards mouse move
messages to Chromium, enabling mouse related events such as `mouseleave`.
Only used when `ignore` is true. If `ignore` is false, forwarding is always
disabled regardless of this value.
Makes the window ignore all mouse events.
All mouse events happened in this window will be passed to the window below
this window, but if this window has focus, it will still receive keyboard
events.
#### `win.setContentProtection(enable)` _macOS_ _Windows_
* `enable` boolean
Prevents the window contents from being captured by other apps.
On macOS it sets the NSWindow's sharingType to NSWindowSharingNone.
On Windows it calls SetWindowDisplayAffinity with `WDA_EXCLUDEFROMCAPTURE`.
For Windows 10 version 2004 and up the window will be removed from capture entirely,
older Windows versions behave as if `WDA_MONITOR` is applied capturing a black window.
#### `win.setFocusable(focusable)` _macOS_ _Windows_
* `focusable` boolean
Changes whether the window can be focused.
On macOS it does not remove the focus from the window.
#### `win.isFocusable()` _macOS_ _Windows_

* `parent` BrowserWindow | null
Sets `parent` as current window's parent window, passing `null` will turn
current window into a top-level window.
#### `win.getParentWindow()`
Returns `BrowserWindow | null` - The parent window or `null` if there is no parent.
#### `win.getChildWindows()`
Returns `BrowserWindow[]` - All child windows.
#### `win.setAutoHideCursor(autoHide)` _macOS_
* `autoHide` boolean
Controls whether to hide cursor when typing.
#### `win.selectPreviousTab()` _macOS_
Selects the previous tab when native tabs are enabled and there are other
tabs in the window.
#### `win.selectNextTab()` _macOS_
Selects the next tab when native tabs are enabled and there are other
tabs in the window.
#### `win.mergeAllWindows()` _macOS_
Merges all windows into one window with multiple tabs when native tabs
are enabled and there is more than one open window.
#### `win.moveTabToNewWindow()` _macOS_
Moves the current tab into a new window if native tabs are enabled and
there is more than one tab in the current window.
#### `win.toggleTabBar()` _macOS_
Toggles the visibility of the tab bar if native tabs are enabled and
there is only one tab in the current window.
#### `win.addTabbedWindow(browserWindow)` _macOS_
* `browserWindow` BrowserWindow
Adds a window as a tab on this window, after the tab for the window instance.
#### `win.setVibrancy(type)` _macOS_
* `type` string | null - Can be `appearance-based`, `light`, `dark`, `titlebar`,
`selection`, `menu`, `popover`, `sidebar`, `medium-light`, `ultra-dark`, `header`, `sheet`, `window`, `hud`, `fullscreen-ui`, `tooltip`, `content`, `under-window`, or `under-page`. See
the [macOS documentation][vibrancy-docs] for more details.
Adds a vibrancy effect to the browser window. Passing `null` or an empty string
will remove the vibrancy effect on the window.
Note that `appearance-based`, `light`, `dark`, `medium-light`, and `ultra-dark` have been
deprecated and will be removed in an upcoming version of macOS.
#### `win.setTrafficLightPosition(position)` _macOS_
* `position` [Point](structures/point.md)

**Note:** The TouchBar API is currently experimental and may change or be
removed in future Electron releases.
#### `win.setBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md) | null - Attach `browserView` to `win`.
If there are other `BrowserView`s attached, they will be removed from
this window.

# Breaking Changes
Breaking changes will be documented here, and deprecation warnings added to JS code where possible, at least [one major version](tutorial/electron-versioning.md#semver) before the change is made.
### Types of Breaking Changes
This document uses the following convention to categorize breaking changes:
* **API Changed:** An API was changed in such a way that code that has not been updated is guaranteed to throw an exception.
* **Behavior Changed:** The behavior of Electron has changed, but not in such a way that an exception will necessarily be thrown.
* **Default Changed:** Code depending on the old default may break, not necessarily throwing an exception. The old behavior can be restored by explicitly specifying the value.
* **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
* **Removed:** An API or feature was removed, and is no longer supported by Electron.
## Planned Breaking API Changes (20.0)
### Default Changed: renderers without `nodeIntegration: true` are sandboxed by default
Previously, renderers that specified a preload script defaulted to being
unsandboxed. This meant that by default, preload scripts had access to Node.js.
In Electron 20, this default has changed. Beginning in Electron 20, renderers
will be sandboxed by default, unless `nodeIntegration: true` or `sandbox: false`
is specified.
If your preload scripts do not depend on Node, no action is needed. If your
preload scripts _do_ depend on Node, either refactor them to remove Node usage
from the renderer, or explicitly specify `sandbox: false` for the relevant
renderers.
## Planned Breaking API Changes (19.0)
*None (yet)*
## Planned Breaking API Changes (18.0)
### Removed: `nativeWindowOpen`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
Since Electron 15, `nativeWindowOpen` has been enabled by default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (17.0)
### Removed: `desktopCapturer.getSources` in the renderer
The `desktopCapturer.getSources` API is now only available in the main process.
This has been changed in order to improve the default security of Electron
apps.
If you need this functionality, it can be replaced as follows:
```js
// Main process
const { ipcMain, desktopCapturer } = require('electron')
ipcMain.handle(
'DESKTOP_CAPTURER_GET_SOURCES',
(event, opts) => desktopCapturer.getSources(opts)
)
```
```js
// Renderer process
const { ipcRenderer } = require('electron')
const desktopCapturer = {
getSources: (opts) => ipcRenderer.invoke('DESKTOP_CAPTURER_GET_SOURCES', opts)
}
```
However, you should consider further restricting the information returned to
the renderer; for instance, displaying a source selector to the user and only
returning the selected source.
### Deprecated: `nativeWindowOpen`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
Since Electron 15, `nativeWindowOpen` has been enabled by default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (16.0)
### Behavior Changed: `crashReporter` implementation switched to Crashpad on Linux
The underlying implementation of the `crashReporter` API on Linux has changed
from Breakpad to Crashpad, bringing it in line with Windows and Mac. As a
result of this, child processes are now automatically monitored, and calling
`process.crashReporter.start` in Node child processes is no longer needed (and
is not advisable, as it will start a second instance of the Crashpad reporter).
There are also some subtle changes to how annotations will be reported on
Linux, including that long values will no longer be split between annotations
appended with `__1`, `__2` and so on, and instead will be truncated at the
(new, longer) annotation value limit.
### Deprecated: `desktopCapturer.getSources` in the renderer
Usage of the `desktopCapturer.getSources` API in the renderer has been
deprecated and will be removed. This change improves the default security of
Electron apps.
See [here](#removed-desktopcapturergetsources-in-the-renderer) for details on
how to replace this API in your app.
## Planned Breaking API Changes (15.0)
### Default Changed: `nativeWindowOpen` defaults to `true`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
`nativeWindowOpen` is no longer experimental, and is now the default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (14.0)
### Removed: `remote` module
The `remote` module was deprecated in Electron 12, and will be removed in
Electron 14. It is replaced by the
[`@electron/remote`](https://github.com/electron/remote) module.
```js
// Deprecated in Electron 12:
const { BrowserWindow } = require('electron').remote
```
```js
// Replace with:
const { BrowserWindow } = require('@electron/remote')
// In the main process:
require('@electron/remote/main').initialize()
```
### Removed: `app.allowRendererProcessReuse`
The `app.allowRendererProcessReuse` property will be removed as part of our plan to
more closely align with Chromium's process model for security, performance and maintainability.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### Removed: Browser Window Affinity
The `affinity` option when constructing a new `BrowserWindow` will be removed
as part of our plan to more closely align with Chromium's process model for security,
performance and maintainability.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### API Changed: `window.open()`
The optional parameter `frameName` will no longer set the title of the window. This now follows the specification described by the [native documentation](https://developer.mozilla.org/en-US/docs/Web/API/Window/open#parameters) under the corresponding parameter `windowName`.
If you were using this parameter to set the title of a window, you can instead use [win.setTitle(title)](api/browser-window.md#winsettitletitle).
### Removed: `worldSafeExecuteJavaScript`
In Electron 14, `worldSafeExecuteJavaScript` will be removed. There is no alternative, please
ensure your code works with this property enabled. It has been enabled by default since Electron
12.
You will be affected by this change if you use either `webFrame.executeJavaScript` or `webFrame.executeJavaScriptInIsolatedWorld`. You will need to ensure that values returned by either of those methods are supported by the [Context Bridge API](api/context-bridge.md#parameter--error--return-type-support) as these methods use the same value passing semantics.
### Removed: BrowserWindowConstructorOptions inheriting from parent windows
Prior to Electron 14, windows opened with `window.open` would inherit
BrowserWindow constructor options such as `transparent` and `resizable` from
their parent window. Beginning with Electron 14, this behavior is removed, and
windows will not inherit any BrowserWindow constructor options from their
parents.
Instead, explicitly set options for the new window with `setWindowOpenHandler`:
```js
webContents.setWindowOpenHandler((details) => {
return {
action: 'allow',
overrideBrowserWindowOptions: {
// ...
}
}
})
```
### Removed: `additionalFeatures`
The deprecated `additionalFeatures` property in the `new-window` and
`did-create-window` events of WebContents has been removed. Since `new-window`
uses positional arguments, the argument is still present, but will always be
the empty array `[]`. (Though note, the `new-window` event itself is
deprecated, and is replaced by `setWindowOpenHandler`.) Bare keys in window
features will now present as keys with the value `true` in the options object.
```js
// Removed in Electron 14
// Triggered by window.open('...', '', 'my-key')
webContents.on('did-create-window', (window, details) => {
if (details.additionalFeatures.includes('my-key')) {
// ...
}
})
// Replace with
webContents.on('did-create-window', (window, details) => {
if (details.options['my-key']) {
// ...
}
})
```
## Planned Breaking API Changes (13.0)
### API Changed: `session.setPermissionCheckHandler(handler)`
The `handler` methods first parameter was previously always a `webContents`, it can now sometimes be `null`. You should use the `requestingOrigin`, `embeddingOrigin` and `securityOrigin` properties to respond to the permission check correctly. As the `webContents` can be `null` it can no longer be relied on.
```js
// Old code
session.setPermissionCheckHandler((webContents, permission) => {
if (webContents.getURL().startsWith('https://google.com/') && permission === 'notification') {
return true
}
return false
})
// Replace with
session.setPermissionCheckHandler((webContents, permission, requestingOrigin) => {
if (new URL(requestingOrigin).hostname === 'google.com' && permission === 'notification') {
return true
}
return false
})
```
### Removed: `shell.moveItemToTrash()`
The deprecated synchronous `shell.moveItemToTrash()` API has been removed. Use
the asynchronous `shell.trashItem()` instead.
```js
// Removed in Electron 13
shell.moveItemToTrash(path)
// Replace with
shell.trashItem(path).then(/* ... */)
```
### Removed: `BrowserWindow` extension APIs
The deprecated extension APIs have been removed:
* `BrowserWindow.addExtension(path)`
* `BrowserWindow.addDevToolsExtension(path)`
* `BrowserWindow.removeExtension(name)`
* `BrowserWindow.removeDevToolsExtension(name)`
* `BrowserWindow.getExtensions()`
* `BrowserWindow.getDevToolsExtensions()`
Use the session APIs instead:
* `ses.loadExtension(path)`
* `ses.removeExtension(extension_id)`
* `ses.getAllExtensions()`
```js
// Removed in Electron 13
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Replace with
session.defaultSession.loadExtension(path)
```
```js
// Removed in Electron 13
BrowserWindow.removeExtension(name)
BrowserWindow.removeDevToolsExtension(name)
// Replace with
session.defaultSession.removeExtension(extension_id)
```
```js
// Removed in Electron 13
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Replace with
session.defaultSession.getAllExtensions()
```
### Removed: methods in `systemPreferences`
The following `systemPreferences` methods have been deprecated:
* `systemPreferences.isDarkMode()`
* `systemPreferences.isInvertedColorScheme()`
* `systemPreferences.isHighContrastColorScheme()`
Use the following `nativeTheme` properties instead:
* `nativeTheme.shouldUseDarkColors`
* `nativeTheme.shouldUseInvertedColorScheme`
* `nativeTheme.shouldUseHighContrastColors`
```js
// Removed in Electron 13
systemPreferences.isDarkMode()
// Replace with
nativeTheme.shouldUseDarkColors
// Removed in Electron 13
systemPreferences.isInvertedColorScheme()
// Replace with
nativeTheme.shouldUseInvertedColorScheme
// Removed in Electron 13
systemPreferences.isHighContrastColorScheme()
// Replace with
nativeTheme.shouldUseHighContrastColors
```
### Deprecated: WebContents `new-window` event
The `new-window` event of WebContents has been deprecated. It is replaced by [`webContents.setWindowOpenHandler()`](api/web-contents.md#contentssetwindowopenhandlerhandler).
```js
// Deprecated in Electron 13
webContents.on('new-window', (event) => {
event.preventDefault()
})
// Replace with
webContents.setWindowOpenHandler((details) => {
return { action: 'deny' }
})
```
## Planned Breaking API Changes (12.0)
### Removed: Pepper Flash support
Chromium has removed support for Flash, and so we must follow suit. See
Chromium's [Flash Roadmap](https://www.chromium.org/flash-roadmap) for more
details.
### Default Changed: `worldSafeExecuteJavaScript` defaults to `true`
In Electron 12, `worldSafeExecuteJavaScript` will be enabled by default. To restore
the previous behavior, `worldSafeExecuteJavaScript: false` must be specified in WebPreferences.
Please note that setting this option to `false` is **insecure**.
This option will be removed in Electron 14 so please migrate your code to support the default
value.
### Default Changed: `contextIsolation` defaults to `true`
In Electron 12, `contextIsolation` will be enabled by default. To restore
the previous behavior, `contextIsolation: false` must be specified in WebPreferences.
We [recommend having contextIsolation enabled](tutorial/security.md#3-enable-context-isolation-for-remote-content) for the security of your application.
Another implication is that `require()` cannot be used in the renderer process unless
`nodeIntegration` is `true` and `contextIsolation` is `false`.
For more details see: https://github.com/electron/electron/issues/23506
### Removed: `crashReporter.getCrashesDirectory()`
The `crashReporter.getCrashesDirectory` method has been removed. Usage
should be replaced by `app.getPath('crashDumps')`.
```js
// Removed in Electron 12
crashReporter.getCrashesDirectory()
// Replace with
app.getPath('crashDumps')
```
### Removed: `crashReporter` methods in the renderer process
The following `crashReporter` methods are no longer available in the renderer
process:
* `crashReporter.start`
* `crashReporter.getLastCrashReport`
* `crashReporter.getUploadedReports`
* `crashReporter.getUploadToServer`
* `crashReporter.setUploadToServer`
* `crashReporter.getCrashesDirectory`
They should be called only from the main process.
See [#23265](https://github.com/electron/electron/pull/23265) for more details.
### Default Changed: `crashReporter.start({ compress: true })`
The default value of the `compress` option to `crashReporter.start` has changed
from `false` to `true`. This means that crash dumps will be uploaded to the
crash ingestion server with the `Content-Encoding: gzip` header, and the body
will be compressed.
If your crash ingestion server does not support compressed payloads, you can
turn off compression by specifying `{ compress: false }` in the crash reporter
options.
### Deprecated: `remote` module
The `remote` module is deprecated in Electron 12, and will be removed in
Electron 14. It is replaced by the
[`@electron/remote`](https://github.com/electron/remote) module.
```js
// Deprecated in Electron 12:
const { BrowserWindow } = require('electron').remote
```
```js
// Replace with:
const { BrowserWindow } = require('@electron/remote')
// In the main process:
require('@electron/remote/main').initialize()
```
### Deprecated: `shell.moveItemToTrash()`
The synchronous `shell.moveItemToTrash()` has been replaced by the new,
asynchronous `shell.trashItem()`.
```js
// Deprecated in Electron 12
shell.moveItemToTrash(path)
// Replace with
shell.trashItem(path).then(/* ... */)
```
## Planned Breaking API Changes (11.0)
### Removed: `BrowserView.{destroy, fromId, fromWebContents, getAllViews}` and `id` property of `BrowserView`
The experimental APIs `BrowserView.{destroy, fromId, fromWebContents, getAllViews}`
have now been removed. Additionally, the `id` property of `BrowserView`
has also been removed.
For more detailed information, see [#23578](https://github.com/electron/electron/pull/23578).
## Planned Breaking API Changes (10.0)
### Deprecated: `companyName` argument to `crashReporter.start()`
The `companyName` argument to `crashReporter.start()`, which was previously
required, is now optional, and further, is deprecated. To get the same
behavior in a non-deprecated way, you can pass a `companyName` value in
`globalExtra`.
```js
// Deprecated in Electron 10
crashReporter.start({ companyName: 'Umbrella Corporation' })
// Replace with
crashReporter.start({ globalExtra: { _companyName: 'Umbrella Corporation' } })
```
### Deprecated: `crashReporter.getCrashesDirectory()`
The `crashReporter.getCrashesDirectory` method has been deprecated. Usage
should be replaced by `app.getPath('crashDumps')`.
```js
// Deprecated in Electron 10
crashReporter.getCrashesDirectory()
// Replace with
app.getPath('crashDumps')
```
### Deprecated: `crashReporter` methods in the renderer process
Calling the following `crashReporter` methods from the renderer process is
deprecated:
* `crashReporter.start`
* `crashReporter.getLastCrashReport`
* `crashReporter.getUploadedReports`
* `crashReporter.getUploadToServer`
* `crashReporter.setUploadToServer`
* `crashReporter.getCrashesDirectory`
The only non-deprecated methods remaining in the `crashReporter` module in the
renderer are `addExtraParameter`, `removeExtraParameter` and `getParameters`.
All above methods remain non-deprecated when called from the main process.
See [#23265](https://github.com/electron/electron/pull/23265) for more details.
### Deprecated: `crashReporter.start({ compress: false })`
Setting `{ compress: false }` in `crashReporter.start` is deprecated. Nearly
all crash ingestion servers support gzip compression. This option will be
removed in a future version of Electron.
### Default Changed: `enableRemoteModule` defaults to `false`
In Electron 9, using the remote module without explicitly enabling it via the
`enableRemoteModule` WebPreferences option began emitting a warning. In
Electron 10, the remote module is now disabled by default. To use the remote
module, `enableRemoteModule: true` must be specified in WebPreferences:
```js
const w = new BrowserWindow({
webPreferences: {
enableRemoteModule: true
}
})
```
We [recommend moving away from the remote
module](https://medium.com/@nornagon/electrons-remote-module-considered-harmful-70d69500f31).
### `protocol.unregisterProtocol`
### `protocol.uninterceptProtocol`
The APIs are now synchronous and the optional callback is no longer needed.
```javascript
// Deprecated
protocol.unregisterProtocol(scheme, () => { /* ... */ })
// Replace with
protocol.unregisterProtocol(scheme)
```
### `protocol.registerFileProtocol`
### `protocol.registerBufferProtocol`
### `protocol.registerStringProtocol`
### `protocol.registerHttpProtocol`
### `protocol.registerStreamProtocol`
### `protocol.interceptFileProtocol`
### `protocol.interceptStringProtocol`
### `protocol.interceptBufferProtocol`
### `protocol.interceptHttpProtocol`
### `protocol.interceptStreamProtocol`
The APIs are now synchronous and the optional callback is no longer needed.
```javascript
// Deprecated
protocol.registerFileProtocol(scheme, handler, () => { /* ... */ })
// Replace with
protocol.registerFileProtocol(scheme, handler)
```
The registered or intercepted protocol does not have effect on current page
until navigation happens.
### `protocol.isProtocolHandled`
This API is deprecated and users should use `protocol.isProtocolRegistered`
and `protocol.isProtocolIntercepted` instead.
```javascript
// Deprecated
protocol.isProtocolHandled(scheme).then(() => { /* ... */ })
// Replace with
const isRegistered = protocol.isProtocolRegistered(scheme)
const isIntercepted = protocol.isProtocolIntercepted(scheme)
```
## Planned Breaking API Changes (9.0)
### Default Changed: Loading non-context-aware native modules in the renderer process is disabled by default
As of Electron 9 we do not allow loading of non-context-aware native modules in
the renderer process. This is to improve security, performance and maintainability
of Electron as a project.
If this impacts you, you can temporarily set `app.allowRendererProcessReuse` to `false`
to revert to the old behavior. This flag will only be an option until Electron 11 so
you should plan to update your native modules to be context aware.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### Deprecated: `BrowserWindow` extension APIs
The following extension APIs have been deprecated:
* `BrowserWindow.addExtension(path)`
* `BrowserWindow.addDevToolsExtension(path)`
* `BrowserWindow.removeExtension(name)`
* `BrowserWindow.removeDevToolsExtension(name)`
* `BrowserWindow.getExtensions()`
* `BrowserWindow.getDevToolsExtensions()`
Use the session APIs instead:
* `ses.loadExtension(path)`
* `ses.removeExtension(extension_id)`
* `ses.getAllExtensions()`
```js
// Deprecated in Electron 9
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Replace with
session.defaultSession.loadExtension(path)
```
```js
// Deprecated in Electron 9
BrowserWindow.removeExtension(name)
BrowserWindow.removeDevToolsExtension(name)
// Replace with
session.defaultSession.removeExtension(extension_id)
```
```js
// Deprecated in Electron 9
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Replace with
session.defaultSession.getAllExtensions()
```
### Removed: `<webview>.getWebContents()`
This API, which was deprecated in Electron 8.0, is now removed.
```js
// Removed in Electron 9.0
webview.getWebContents()
// Replace with
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())
```
### Removed: `webFrame.setLayoutZoomLevelLimits()`
Chromium has removed support for changing the layout zoom level limits, and it
is beyond Electron's capacity to maintain it. The function was deprecated in
Electron 8.x, and has been removed in Electron 9.x. The layout zoom level limits
are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
### Behavior Changed: Sending non-JS objects over IPC now throws an exception
In Electron 8.0, IPC was changed to use the Structured Clone Algorithm,
bringing significant performance improvements. To help ease the transition, the
old IPC serialization algorithm was kept and used for some objects that aren't
serializable with Structured Clone. In particular, DOM objects (e.g. `Element`,
`Location` and `DOMMatrix`), Node.js objects backed by C++ classes (e.g.
`process.env`, some members of `Stream`), and Electron objects backed by C++
classes (e.g. `WebContents`, `BrowserWindow` and `WebFrame`) are not
serializable with Structured Clone. Whenever the old algorithm was invoked, a
deprecation warning was printed.
In Electron 9.0, the old serialization algorithm has been removed, and sending
such non-serializable objects will now throw an "object could not be cloned"
error.
### API Changed: `shell.openItem` is now `shell.openPath`
The `shell.openItem` API has been replaced with an asynchronous `shell.openPath` API.
You can see the original API proposal and reasoning [here](https://github.com/electron/governance/blob/main/wg-api/spec-documents/shell-openitem.md).
## Planned Breaking API Changes (8.0)
### Behavior Changed: Values sent over IPC are now serialized with Structured Clone Algorithm
The algorithm used to serialize objects sent over IPC (through
`ipcRenderer.send`, `ipcRenderer.sendSync`, `WebContents.send` and related
methods) has been switched from a custom algorithm to V8's built-in [Structured
Clone Algorithm][SCA], the same algorithm used to serialize messages for
`postMessage`. This brings about a 2x performance improvement for large
messages, but also brings some breaking changes in behavior.
* Sending Functions, Promises, WeakMaps, WeakSets, or objects containing any
such values, over IPC will now throw an exception, instead of silently
converting the functions to `undefined`.
```js
// Previously:
ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
// => results in { value: 3 } arriving in the main process
// From Electron 8:
ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
// => throws Error("() => {} could not be cloned.")
```
* `NaN`, `Infinity` and `-Infinity` will now be correctly serialized, instead
of being converted to `null`.
* Objects containing cyclic references will now be correctly serialized,
instead of being converted to `null`.
* `Set`, `Map`, `Error` and `RegExp` values will be correctly serialized,
instead of being converted to `{}`.
* `BigInt` values will be correctly serialized, instead of being converted to
`null`.
* Sparse arrays will be serialized as such, instead of being converted to dense
arrays with `null`s.
* `Date` objects will be transferred as `Date` objects, instead of being
converted to their ISO string representation.
* Typed Arrays (such as `Uint8Array`, `Uint16Array`, `Uint32Array` and so on)
will be transferred as such, instead of being converted to Node.js `Buffer`.
* Node.js `Buffer` objects will be transferred as `Uint8Array`s. You can
convert a `Uint8Array` back to a Node.js `Buffer` by wrapping the underlying
`ArrayBuffer`:
```js
Buffer.from(value.buffer, value.byteOffset, value.byteLength)
```
Sending any objects that aren't native JS types, such as DOM objects (e.g.
`Element`, `Location`, `DOMMatrix`), Node.js objects (e.g. `process.env`,
`Stream`), or Electron objects (e.g. `WebContents`, `BrowserWindow`,
`WebFrame`) is deprecated. In Electron 8, these objects will be serialized as
before with a DeprecationWarning message, but starting in Electron 9, sending
these kinds of objects will throw a 'could not be cloned' error.
[SCA]: https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm
### Deprecated: `<webview>.getWebContents()`
This API is implemented using the `remote` module, which has both performance
and security implications. Therefore its usage should be explicit.
```js
// Deprecated
webview.getWebContents()
// Replace with
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())
```
However, it is recommended to avoid using the `remote` module altogether.
```js
// main
const { ipcMain, webContents } = require('electron')
const getGuestForWebContents = (webContentsId, contents) => {
const guest = webContents.fromId(webContentsId)
if (!guest) {
throw new Error(`Invalid webContentsId: ${webContentsId}`)
}
if (guest.hostWebContents !== contents) {
throw new Error('Access denied to webContents')
}
return guest
}
ipcMain.handle('openDevTools', (event, webContentsId) => {
const guest = getGuestForWebContents(webContentsId, event.sender)
guest.openDevTools()
})
// renderer
const { ipcRenderer } = require('electron')
ipcRenderer.invoke('openDevTools', webview.getWebContentsId())
```
### Deprecated: `webFrame.setLayoutZoomLevelLimits()`
Chromium has removed support for changing the layout zoom level limits, and it
is beyond Electron's capacity to maintain it. The function will emit a warning
in Electron 8.x, and cease to exist in Electron 9.x. The layout zoom level
limits are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
### Deprecated events in `systemPreferences`
The following `systemPreferences` events have been deprecated:
* `inverted-color-scheme-changed`
* `high-contrast-color-scheme-changed`
Use the new `updated` event on the `nativeTheme` module instead.
```js
// Deprecated
systemPreferences.on('inverted-color-scheme-changed', () => { /* ... */ })
systemPreferences.on('high-contrast-color-scheme-changed', () => { /* ... */ })
// Replace with
nativeTheme.on('updated', () => { /* ... */ })
```
### Deprecated: methods in `systemPreferences`
The following `systemPreferences` methods have been deprecated:
* `systemPreferences.isDarkMode()`
* `systemPreferences.isInvertedColorScheme()`
* `systemPreferences.isHighContrastColorScheme()`
Use the following `nativeTheme` properties instead:
* `nativeTheme.shouldUseDarkColors`
* `nativeTheme.shouldUseInvertedColorScheme`
* `nativeTheme.shouldUseHighContrastColors`
```js
// Deprecated
systemPreferences.isDarkMode()
// Replace with
nativeTheme.shouldUseDarkColors
// Deprecated
systemPreferences.isInvertedColorScheme()
// Replace with
nativeTheme.shouldUseInvertedColorScheme
// Deprecated
systemPreferences.isHighContrastColorScheme()
// Replace with
nativeTheme.shouldUseHighContrastColors
```
## Planned Breaking API Changes (7.0)
### Deprecated: Atom.io Node Headers URL
This is the URL specified as `disturl` in a `.npmrc` file or as the `--dist-url`
command line flag when building native Node modules. Both will be supported for
the foreseeable future but it is recommended that you switch.
Deprecated: https://atom.io/download/electron
Replace with: https://electronjs.org/headers
### API Changed: `session.clearAuthCache()` no longer accepts options
The `session.clearAuthCache` API no longer accepts options for what to clear, and instead unconditionally clears the whole cache.
```js
// Deprecated
session.clearAuthCache({ type: 'password' })
// Replace with
session.clearAuthCache()
```
### API Changed: `powerMonitor.querySystemIdleState` is now `powerMonitor.getSystemIdleState`
```js
// Removed in Electron 7.0
powerMonitor.querySystemIdleState(threshold, callback)
// Replace with synchronous API
const idleState = powerMonitor.getSystemIdleState(threshold)
```
### API Changed: `powerMonitor.querySystemIdleTime` is now `powerMonitor.getSystemIdleTime`
```js
// Removed in Electron 7.0
powerMonitor.querySystemIdleTime(callback)
// Replace with synchronous API
const idleTime = powerMonitor.getSystemIdleTime()
```
### API Changed: `webFrame.setIsolatedWorldInfo` replaces separate methods
```js
// Removed in Electron 7.0
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)
webFrame.setIsolatedWorldHumanReadableName(worldId, name)
webFrame.setIsolatedWorldSecurityOrigin(worldId, securityOrigin)
// Replace with
webFrame.setIsolatedWorldInfo(
worldId,
{
securityOrigin: 'some_origin',
name: 'human_readable_name',
csp: 'content_security_policy'
})
```
### Removed: `marked` property on `getBlinkMemoryInfo`
This property was removed in Chromium 77, and as such is no longer available.
### Behavior Changed: `webkitdirectory` attribute for `<input type="file"/>` now lists directory contents
The `webkitdirectory` property on HTML file inputs allows them to select folders.
Previous versions of Electron had an incorrect implementation where the `event.target.files`
of the input returned a `FileList` that returned one `File` corresponding to the selected folder.
As of Electron 7, that `FileList` is now list of all files contained within
the folder, similarly to Chrome, Firefox, and Edge
([link to MDN docs](https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/webkitdirectory)).
As an illustration, take a folder with this structure:
```console
folder
├── file1
├── file2
└── file3
```
In Electron <=6, this would return a `FileList` with a `File` object for:
```console
path/to/folder
```
In Electron 7, this now returns a `FileList` with a `File` object for:
```console
/path/to/folder/file3
/path/to/folder/file2
/path/to/folder/file1
```
Note that `webkitdirectory` no longer exposes the path to the selected folder.
If you require the path to the selected folder rather than the folder contents,
see the `dialog.showOpenDialog` API ([link](api/dialog.md#dialogshowopendialogbrowserwindow-options)).
### API Changed: Callback-based versions of promisified APIs
Electron 5 and Electron 6 introduced Promise-based versions of existing
asynchronous APIs and deprecated their older, callback-based counterparts.
In Electron 7, all deprecated callback-based APIs are now removed.
These functions now only return Promises:
* `app.getFileIcon()` [#15742](https://github.com/electron/electron/pull/15742)
* `app.dock.show()` [#16904](https://github.com/electron/electron/pull/16904)
* `contentTracing.getCategories()` [#16583](https://github.com/electron/electron/pull/16583)

* `contentTracing.startRecording()` [#16584](https://github.com/electron/electron/pull/16584)
* `contentTracing.stopRecording()` [#16584](https://github.com/electron/electron/pull/16584)
* `contents.executeJavaScript()` [#17312](https://github.com/electron/electron/pull/17312)
* `cookies.flushStore()` [#16464](https://github.com/electron/electron/pull/16464)
* `cookies.get()` [#16464](https://github.com/electron/electron/pull/16464)
* `cookies.remove()` [#16464](https://github.com/electron/electron/pull/16464)
* `cookies.set()` [#16464](https://github.com/electron/electron/pull/16464)
* `debugger.sendCommand()` [#16861](https://github.com/electron/electron/pull/16861)
* `dialog.showCertificateTrustDialog()` [#17181](https://github.com/electron/electron/pull/17181)
* `inAppPurchase.getProducts()` [#17355](https://github.com/electron/electron/pull/17355)
* `inAppPurchase.purchaseProduct()`[#17355](https://github.com/electron/electron/pull/17355)
* `netLog.stopLogging()` [#16862](https://github.com/electron/electron/pull/16862)
* `session.clearAuthCache()` [#17259](https://github.com/electron/electron/pull/17259)
* `session.clearCache()` [#17185](https://github.com/electron/electron/pull/17185)
* `session.clearHostResolverCache()` [#17229](https://github.com/electron/electron/pull/17229)
* `session.clearStorageData()` [#17249](https://github.com/electron/electron/pull/17249)
* `session.getBlobData()` [#17303](https://github.com/electron/electron/pull/17303)
* `session.getCacheSize()` [#17185](https://github.com/electron/electron/pull/17185)
* `session.resolveProxy()` [#17222](https://github.com/electron/electron/pull/17222)

## Planned Breaking API Changes (6.0)
### API Changed: `win.setMenu(null)` is now `win.removeMenu()`
```js
// Deprecated
win.setMenu(null)
// Replace with
win.removeMenu()
```
### API Changed: `electron.screen` in the renderer process should be accessed via `remote`
```js
// Deprecated
require('electron').screen
// Replace with
require('electron').remote.screen
```
### API Changed: `require()`ing node builtins in sandboxed renderers no longer implicitly loads the `remote` version
```js
// Deprecated
require('child_process')
// Replace with
require('electron').remote.require('child_process')
// Deprecated
require('fs')
// Replace with
require('electron').remote.require('fs')
// Deprecated
require('os')
// Replace with
require('electron').remote.require('os')
// Deprecated
require('path')
// Replace with
require('electron').remote.require('path')
```
### Deprecated: `powerMonitor.querySystemIdleState` replaced with `powerMonitor.getSystemIdleState`
```js
// Deprecated
powerMonitor.querySystemIdleState(threshold, callback)
// Replace with synchronous API
const idleState = powerMonitor.getSystemIdleState(threshold)
```
### Deprecated: `powerMonitor.querySystemIdleTime` replaced with `powerMonitor.getSystemIdleTime`
```js
// Deprecated
powerMonitor.querySystemIdleTime(callback)
// Replace with synchronous API
const idleTime = powerMonitor.getSystemIdleTime()
```
### Deprecated: `app.enableMixedSandbox()` is no longer needed
```js
// Deprecated
app.enableMixedSandbox()
```
Mixed-sandbox mode is now enabled by default.
### Deprecated: `Tray.setHighlightMode`
Under macOS Catalina our former Tray implementation breaks.
Apple's native substitute doesn't support changing the highlighting behavior.
```js
// Deprecated
tray.setHighlightMode(mode)
// API will be removed in v7.0 without replacement.
```
## Planned Breaking API Changes (5.0)
### Default Changed: `nodeIntegration` and `webviewTag` default to false, `contextIsolation` defaults to true
The following `webPreferences` option default values are deprecated in favor of the new defaults listed below.
| Property | Deprecated Default | New Default |
|----------|--------------------|-------------|
| `contextIsolation` | `false` | `true` |
| `nodeIntegration` | `true` | `false` |
| `webviewTag` | `nodeIntegration` if set else `true` | `false` |
E.g. Re-enabling the webviewTag
```js
const w = new BrowserWindow({
webPreferences: {
webviewTag: true
}
})
```
### Behavior Changed: `nodeIntegration` in child windows opened via `nativeWindowOpen`
Child windows opened with the `nativeWindowOpen` option will always have Node.js integration disabled, unless `nodeIntegrationInSubFrames` is `true`.
### API Changed: Registering privileged schemes must now be done before app ready
Renderer process APIs `webFrame.registerURLSchemeAsPrivileged` and `webFrame.registerURLSchemeAsBypassingCSP` as well as browser process API `protocol.registerStandardSchemes` have been removed.
A new API, `protocol.registerSchemesAsPrivileged` has been added and should be used for registering custom schemes with the required privileges. Custom schemes are required to be registered before app ready.
### Deprecated: `webFrame.setIsolatedWorld*` replaced with `webFrame.setIsolatedWorldInfo`
```js
// Deprecated
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)
webFrame.setIsolatedWorldHumanReadableName(worldId, name)
webFrame.setIsolatedWorldSecurityOrigin(worldId, securityOrigin)
// Replace with
webFrame.setIsolatedWorldInfo(
worldId,
{
securityOrigin: 'some_origin',
name: 'human_readable_name',
csp: 'content_security_policy'
})
```
### API Changed: `webFrame.setSpellCheckProvider` now takes an asynchronous callback
The `spellCheck` callback is now asynchronous, and `autoCorrectWord` parameter has been removed.
```js
// Deprecated
webFrame.setSpellCheckProvider('en-US', true, {
spellCheck: (text) => {
return !spellchecker.isMisspelled(text)
}
})
// Replace with
webFrame.setSpellCheckProvider('en-US', {
spellCheck: (words, callback) => {
callback(words.filter(text => spellchecker.isMisspelled(text)))
}
})
```
### API Changed: `webContents.getZoomLevel` and `webContents.getZoomFactor` are now synchronous
`webContents.getZoomLevel` and `webContents.getZoomFactor` no longer take callback parameters,
instead directly returning their number values.
```js
// Deprecated
webContents.getZoomLevel((level) => {
console.log(level)
})
// Replace with
const level = webContents.getZoomLevel()
console.log(level)
```
```js
// Deprecated
webContents.getZoomFactor((factor) => {
console.log(factor)
})
// Replace with
const factor = webContents.getZoomFactor()
console.log(factor)
```
## Planned Breaking API Changes (4.0)
The following list includes the breaking API changes made in Electron 4.0.

app.on('second-instance', (event, argv, cwd) => {
/* ... */
})
```
### `app.releaseSingleInstance`
```js
// Deprecated
app.releaseSingleInstance()
// Replace with
app.releaseSingleInstanceLock()
```
### `app.getGPUInfo`
```js
app.getGPUInfo('complete')
// Now behaves the same with `basic` on macOS
app.getGPUInfo('basic')
```
### `win_delay_load_hook`
When building native modules for windows, the `win_delay_load_hook` variable in
the module's `binding.gyp` must be true (which is the default). If this hook is
not present, then the native module will fail to load on Windows, with an error
message like `Cannot find module`. See the [native module

// do something
}
})

```
### `webFrame`
```js
// Deprecated
webFrame.registerURLSchemeAsSecure('app')
// Replace with
protocol.registerStandardSchemes(['app'], { secure: true })
// Deprecated
webFrame.registerURLSchemeAsPrivileged('app', { secure: true })
// Replace with
protocol.registerStandardSchemes(['app'], { secure: true })
```
### `<webview>`
```js
// Removed
webview.setAttribute('disableguestresize', '')

Deprecated: https://atom.io/download/atom-shell
Replace with: https://atom.io/download/electron
## Breaking API Changes (2.0)

const windowA = new BrowserWindow(optionsA)
// Replace with
const optionsB = { titleBarStyle: 'hiddenInset' }
const windowB = new BrowserWindow(optionsB)
```
### `menu`
```js

read-only properties for consistency with the other `process.versions`
properties set by Node.
### `webContents`
```js
// Removed
webContents.setZoomLevelLimits(1, 2)
// Replaced with
webContents.setVisualZoomLevelLimits(1, 2)

```
### Duplicate ARM Assets
Each Electron release includes two identical ARM builds with slightly different
filenames, like `electron-v1.7.3-linux-arm.zip` and
`electron-v1.7.3-linux-armv7l.zip`. The asset with the `v7l` prefix was added
to clarify to users which ARM version it supports, and to disambiguate it from
future armv6l and arm64 assets that may be produced.
The file _without the prefix_ is still being published to avoid breaking any
setups that may be consuming it. Starting at 2.0, the unprefixed file will
no longer be published.
For details, see
[6986](https://github.com/electron/electron/pull/6986)
and
[7189](https://github.com/electron/electron/pull/7189).

### Electron Version
15.2.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10 enterprise, 21H1
### What arch are you using?
x64
### Last Known Working Electron version
13.2.1
### Expected Behavior
When moving a child view partly outside of it's parents window bounds I expect it to keep it's size and position.
### Actual Behavior
When moving a child view partly outside of it's parent window it's bounds are resized.
### Testcase Gist URL
https://gist.github.com/900f0a593260572e8292e6db0e71f8de
### Additional Information
The change was introduced between electron versions 13.2.1 and 13.2.2 (which can be tested using the fiddle). It's likely due to the change included inside the PR: https://github.com/electron/electron/pull/30540
Our use case is that we have a virtual keyboard and logic to shift a browser view position to fit focused elements inside the visible area when the keyboard is opened. We are shifting the brower view by setting a negative y-position for the bounds, as seen in the provided fiddle.
The new behavior with a resized viewport will affect the sizing and positioning of elements inside the viewport.

[Bug]: current pywin32 win build directions don't make sense for depot_tools python
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
main
### What operating system are you using?
Windows
### Operating System Version
win10 21h2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
python prereqs used to be:
- Contrary to the depot_tools setup instructions linked below, you will need to use your locally installed Python with at least version 2.7.10 (with support for TLS 1.2). To do so, make sure that in PATH, your locally installed Python comes before the depot_tools folder. Right now depot_tools still comes with Python 2.7.6, which will cause the gclient command to fail (see https://crbug.com/868864).
- [Python for Windows (pywin32) Extensions](https://pypi.org/project/pywin32/#files) is also needed in order to run the build process.
The first part has been removed so presumably one is expected to use depot_tools python now. But it doesn't have pip
### Actual Behavior
- Which python are you supposed to use, depot_tools or own?
- Is pywin32 still needed?
- For which part of the build?
- if so, how do you install it into depot_tools
### Testcase Gist URL
_No response_

# Build Instructions (Windows)
Follow the guidelines below for building **Electron itself** on Windows, for the purposes of creating custom Electron binaries. For bundling and distributing your app code with the prebuilt Electron binaries, see the [application distribution][application-distribution] guide.
[application-distribution]: ../tutorial/application-distribution.md
## Prerequisites
* Windows 10 / Server 2012 R2 or higher
* Visual Studio 2017 15.7.2 or higher - [download VS 2019 Community Edition for
free](https://www.visualstudio.com/vs/)
* See [the Chromium build documentation](https://chromium.googlesource.com/chromium/src/+/main/docs/windows_build_instructions.md#visual-studio) for more details on which Visual Studio
components are required.
* If your Visual Studio is installed in a directory other than the default, you'll need to
set a few environment variables to point the toolchains to your installation path.
* `vs2019_install = DRIVE:\path\to\Microsoft Visual Studio\2019\Community`, replacing `2019` and `Community` with your installed versions and replacing `DRIVE:` with the drive that Visual Studio is on. Often, this will be `C:`.
* `WINDOWSSDKDIR = DRIVE:\path\to\Windows Kits\10`, replacing `DRIVE:` with the drive that Windows Kits is on. Often, this will be `C:`.
* [Python for Windows (pywin32) Extensions](https://pypi.org/project/pywin32/#files)
is also needed in order to run the build process.
* [Node.js](https://nodejs.org/download/)
* [Git](https://git-scm.com)
* Debugging Tools for Windows of Windows SDK 10.0.15063.468 if you plan on
creating a full distribution since `symstore.exe` is used for creating a symbol
store from `.pdb` files.
* Different versions of the SDK can be installed side by side. To install the
SDK, open Visual Studio Installer, select
`Modify` → `Individual Components`, scroll down and select the appropriate
Windows SDK to install. Another option would be to look at the
[Windows SDK and emulator archive](https://developer.microsoft.com/en-us/windows/downloads/sdk-archive)
and download the standalone version of the SDK respectively.
* The SDK Debugging Tools must also be installed. If the Windows 10 SDK was installed
via the Visual Studio installer, then they can be installed by going to:
`Control Panel` → `Programs` → `Programs and Features` → Select the "Windows Software Development Kit" →
`Change` → `Change` → Check "Debugging Tools For Windows" → `Change`.
Or, you can download the standalone SDK installer and use it to install the Debugging Tools.
If you don't currently have a Windows installation,
[dev.microsoftedge.com](https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/)
has timebombed versions of Windows that you can use to build Electron.
Building Electron is done entirely with command-line scripts and cannot be done
with Visual Studio. You can develop Electron with any editor but support for
building with Visual Studio will come in the future.
**Note:** Even though Visual Studio is not used for building, it's still
**required** because we need the build toolchains it provides.
## Exclude source tree from Windows Security
Windows Security doesn't like one of the files in the Chromium source code
(see https://crbug.com/441184), so it will constantly delete it, causing `gclient sync` issues.
You can exclude the source tree from being monitored by Windows Security by
[following these instructions](https://support.microsoft.com/en-us/windows/add-an-exclusion-to-windows-security-811816c0-4dfd-af4a-47e4-c301afe13b26).
## Building
See [Build Instructions: GN](build-instructions-gn.md)
## 32bit Build
To build for the 32bit target, you need to pass `target_cpu = "x86"` as a GN
arg. You can build the 32bit target alongside the 64bit target by using a
different output directory for GN, e.g. `out/Release-x86`, with different
arguments.
```powershell
$ gn gen out/Release-x86 --args="import(\"//electron/build/args/release.gn\") target_cpu=\"x86\""
```
The other building steps are exactly the same.
## Visual Studio project
To generate a Visual Studio project, you can pass the `--ide=vs2017` parameter
to `gn gen`:
```powershell
$ gn gen out/Testing --ide=vs2017
```
## Troubleshooting
### Command xxxx not found
If you encountered an error like `Command xxxx not found`, you may try to use
the `VS2015 Command Prompt` console to execute the build scripts.
### Fatal internal compiler error: C1001
Make sure you have the latest Visual Studio update installed.
### LNK1181: cannot open input file 'kernel32.lib'
Try reinstalling 32bit Node.js.
### Error: ENOENT, stat 'C:\Users\USERNAME\AppData\Roaming\npm'
Creating that directory [should fix the problem](https://stackoverflow.com/a/25095327/102704):
```powershell
$ mkdir ~\AppData\Roaming\npm
```
### node-gyp is not recognized as an internal or external command
You may get this error if you are using Git Bash for building, you should use
PowerShell or VS2015 Command Prompt instead.
### cannot create directory at '...': Filename too long
node.js has some [extremely long pathnames](https://github.com/electron/node/tree/electron/deps/npm/node_modules/libnpx/node_modules/yargs/node_modules/read-pkg-up/node_modules/read-pkg/node_modules/load-json-file/node_modules/parse-json/node_modules/error-ex/node_modules/is-arrayish), and by default git on windows doesn't handle long pathnames correctly (even though windows supports them). This should fix it:
```sh
$ git config --system core.longpaths true
```
### error: use of undeclared identifier 'DefaultDelegateCheckMode'
This can happen during build, when Debugging Tools for Windows has been installed with Windows Driver Kit. Uninstall Windows Driver Kit and install Debugging Tools with steps described above.
### ImportError: No module named win32file
Make sure you have installed `pywin32` with `pip install pywin32`.
### Build Scripts Hang Until Keypress
This bug is a "feature" of Windows' command prompt. It happens when clicking inside the prompt window with
`QuickEdit` enabled and is intended to allow selecting and copying output text easily.
Since each accidental click will pause the build process, you might want to disable this
feature in the command prompt properties.

### Electron Version
17.1.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 21.10
### What arch are you using?
x64
### Last Known Working Electron version
none
### Expected Behavior
@types/node match the node version that electron ships with
### Actual Behavior
`@types/node` are on version 14 whereas electron ships node 16
This causes typescript errors like `Cannot find name 'performance'` even though this code runs just fine with electron / node 16.
**Proposed solution:** Updating `@types/node` to the version of node that electron ships with

### Electron Version
17.1.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 21.10
### What arch are you using?
x64
### Last Known Working Electron version
none
### Expected Behavior
@types/node match the node version that electron ships with
### Actual Behavior
`@types/node` are on version 14 whereas electron ships node 16
This causes typescript errors like `Cannot find name 'performance'` even though this code runs just fine with electron / node 16.
**Proposed solution:** Updating `@types/node` to the version of node that electron ships with

### Electron Version
17.1.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 21.10
### What arch are you using?
x64
### Last Known Working Electron version
none
### Expected Behavior
@types/node match the node version that electron ships with
### Actual Behavior
`@types/node` are on version 14 whereas electron ships node 16
This causes typescript errors like `Cannot find name 'performance'` even though this code runs just fine with electron / node 16.
**Proposed solution:** Updating `@types/node` to the version of node that electron ships with

// Rip global off of window (which is also global) so that webpack doesn't
// auto replace it with a looped reference to this file

### Electron Version
17.1.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 21.10
### What arch are you using?
x64
### Last Known Working Electron version
none
### Expected Behavior
@types/node match the node version that electron ships with
### Actual Behavior
`@types/node` are on version 14 whereas electron ships node 16
This causes typescript errors like `Cannot find name 'performance'` even though this code runs just fine with electron / node 16.
**Proposed solution:** Updating `@types/node` to the version of node that electron ships with

# webFrame
> Customize the rendering of the current web page.
Process: [Renderer](../glossary.md#renderer-process)
`webFrame` export of the Electron module is an instance of the `WebFrame`
class representing the current frame. Sub-frames can be retrieved by
certain properties and methods (e.g. `webFrame.firstChild`).
An example of zooming current page to 200%.
```javascript
const { webFrame } = require('electron')
webFrame.setZoomFactor(2)
```
## Methods
The `WebFrame` class has the following instance methods:
### `webFrame.setZoomFactor(factor)`
* `factor` Double - Zoom factor; default is 1.0.
Changes the zoom factor to the specified factor. Zoom factor is
zoom percent divided by 100, so 300% = 3.0.
The factor must be greater than 0.0.
### `webFrame.getZoomFactor()`
Returns `number` - The current zoom factor.
### `webFrame.setZoomLevel(level)`
* `level` number - Zoom level.
Changes the zoom level to the specified level. The original size is 0 and each
increment above or below represents zooming 20% larger or smaller to default
limits of 300% and 50% of original size, respectively.
> **NOTE**: The zoom policy at the Chromium level is same-origin, meaning that the
> zoom level for a specific domain propagates across all instances of windows with
> the same domain. Differentiating the window URLs will make zoom work per-window.
### `webFrame.getZoomLevel()`
Returns `number` - The current zoom level.
### `webFrame.setVisualZoomLevelLimits(minimumLevel, maximumLevel)`
* `minimumLevel` number
* `maximumLevel` number
Sets the maximum and minimum pinch-to-zoom level.
> **NOTE**: Visual zoom is disabled by default in Electron. To re-enable it, call:
>
> ```js
> webFrame.setVisualZoomLevelLimits(1, 3)
> ```
> **NOTE**: Visual zoom only applies to pinch-to-zoom behavior. Cmd+/-/0 zoom shortcuts are
> controlled by the 'zoomIn', 'zoomOut', and 'resetZoom' MenuItem roles in the application
> Menu. To disable shortcuts, manually [define the Menu](./menu.md#examples) and omit zoom roles
> from the definition.
### `webFrame.setSpellCheckProvider(language, provider)`
* `language` string
* `provider` Object
* `spellCheck` Function
* `words` string[]
* `callback` Function
* `misspeltWords` string[]
Sets a provider for spell checking in input fields and text areas.
If you want to use this method you must disable the builtin spellchecker when you
construct the window.
```js
const mainWindow = new BrowserWindow({
webPreferences: {
spellcheck: false
}
})
```
The `provider` must be an object that has a `spellCheck` method that accepts
an array of individual words for spellchecking.
The `spellCheck` function runs asynchronously and calls the `callback` function
with an array of misspelt words when complete.
An example of using [node-spellchecker][spellchecker] as provider:
```javascript
const { webFrame } = require('electron')
const spellChecker = require('spellchecker')
webFrame.setSpellCheckProvider('en-US', {
spellCheck (words, callback) {
setTimeout(() => {
const spellchecker = require('spellchecker')
const misspelled = words.filter(x => spellchecker.isMisspelled(x))
callback(misspelled)
}, 0)
}
})
```
#### `webFrame.insertCSS(css[, options])`
* `css` string
* `options` Object (optional)
* `cssOrigin` string (optional) - Can be either 'user' or 'author'. Sets the [cascade origin](https://www.w3.org/TR/css3-cascade/#cascade-origin) of the inserted stylesheet. Default is 'author'.
Returns `string` - A key for the inserted CSS that can later be used to remove
the CSS via `webFrame.removeInsertedCSS(key)`.
Injects CSS into the current web page and returns a unique key for the inserted
stylesheet.
### `webFrame.removeInsertedCSS(key)`
* `key` string
Removes the inserted CSS from the current web page. The stylesheet is identified
by its key, which is returned from `webFrame.insertCSS(css)`.
### `webFrame.insertText(text)`
* `text` string
Inserts `text` to the focused element.
### `webFrame.executeJavaScript(code[, userGesture, callback])`
* `code` string
* `userGesture` boolean (optional) - Default is `false`.
* `callback` Function (optional) - Called after script has been executed. Unless
the frame is suspended (e.g. showing a modal alert), execution will be
synchronous and the callback will be invoked before the method returns. For
compatibility with an older version of this method, the error parameter is
second.
* `result` Any
* `error` Error
Returns `Promise<any>` - A promise that resolves with the result of the executed
code or is rejected if execution throws or results in a rejected promise.
Evaluates `code` in page.
In the browser window some HTML APIs like `requestFullScreen` can only be
invoked by a gesture from the user. Setting `userGesture` to `true` will remove
this limitation.
### `webFrame.executeJavaScriptInIsolatedWorld(worldId, scripts[, userGesture, callback])`
* `worldId` Integer - The ID of the world to run the javascript
in, `0` is the default main world (where content runs), `999` is the
world used by Electron's `contextIsolation` feature. Accepts values
in the range 1..536870911.
* `scripts` [WebSource[]](structures/web-source.md)
* `userGesture` boolean (optional) - Default is `false`.
* `callback` Function (optional) - Called after script has been executed. Unless
the frame is suspended (e.g. showing a modal alert), execution will be
synchronous and the callback will be invoked before the method returns. For
compatibility with an older version of this method, the error parameter is
second.
* `result` Any
* `error` Error
Returns `Promise<any>` - A promise that resolves with the result of the executed
code or is rejected if execution could not start.
Works like `executeJavaScript` but evaluates `scripts` in an isolated context.
Note that when the execution of script fails, the returned promise will not
reject and the `result` would be `undefined`. This is because Chromium does not
dispatch errors of isolated worlds to foreign worlds.
### `webFrame.setIsolatedWorldInfo(worldId, info)`
* `worldId` Integer - The ID of the world to run the javascript in, `0` is the default world, `999` is the world used by Electrons `contextIsolation` feature. Chrome extensions reserve the range of IDs in `[1 << 20, 1 << 29)`. You can provide any integer here.
* `info` Object
* `securityOrigin` string (optional) - Security origin for the isolated world.
* `csp` string (optional) - Content Security Policy for the isolated world.
* `name` string (optional) - Name for isolated world. Useful in devtools.
Set the security origin, content security policy and name of the isolated world.
Note: If the `csp` is specified, then the `securityOrigin` also has to be specified.
### `webFrame.getResourceUsage()`
Returns `Object`:
* `images` [MemoryUsageDetails](structures/memory-usage-details.md)
* `scripts` [MemoryUsageDetails](structures/memory-usage-details.md)
* `cssStyleSheets` [MemoryUsageDetails](structures/memory-usage-details.md)
* `xslStyleSheets` [MemoryUsageDetails](structures/memory-usage-details.md)
* `fonts` [MemoryUsageDetails](structures/memory-usage-details.md)
* `other` [MemoryUsageDetails](structures/memory-usage-details.md)
Returns an object describing usage information of Blink's internal memory
caches.
```javascript
const { webFrame } = require('electron')
console.log(webFrame.getResourceUsage())
```
This will generate:
```javascript
{
images: {
count: 22,
size: 2549,
liveSize: 2542
},
cssStyleSheets: { /* same with "images" */ },
xslStyleSheets: { /* same with "images" */ },
fonts: { /* same with "images" */ },
other: { /* same with "images" */ }
}
```
### `webFrame.clearCache()`
Attempts to free memory that is no longer being used (like images from a
previous navigation).
Note that blindly calling this method probably makes Electron slower since it
will have to refill these emptied caches, you should only call it if an event
in your app has occurred that makes you think your page is actually using less
memory (i.e. you have navigated from a super heavy page to a mostly empty one,
and intend to stay there).
[spellchecker]: https://github.com/atom/node-spellchecker
### `webFrame.getFrameForSelector(selector)`
* `selector` string - CSS selector for a frame element.
Returns `WebFrame` - The frame element in `webFrame's` document selected by
`selector`, `null` would be returned if `selector` does not select a frame or
if the frame is not in the current renderer process.
### `webFrame.findFrameByName(name)`
* `name` string
Returns `WebFrame` - A child of `webFrame` with the supplied `name`, `null`
would be returned if there's no such frame or if the frame is not in the current
renderer process.
### `webFrame.findFrameByRoutingId(routingId)`
* `routingId` Integer - An `Integer` representing the unique frame id in the
current renderer process. Routing IDs can be retrieved from `WebFrame`
instances (`webFrame.routingId`) and are also passed by frame
specific `WebContents` navigation events (e.g. `did-frame-navigate`)
Returns `WebFrame` - that has the supplied `routingId`, `null` if not found.
### `webFrame.isWordMisspelled(word)`
* `word` string - The word to be spellchecked.
Returns `boolean` - True if the word is misspelled according to the built in
spellchecker, false otherwise. If no dictionary is loaded, always return false.
### `webFrame.getWordSuggestions(word)`
* `word` string - The misspelled word.
Returns `string[]` - A list of suggested words for a given word. If the word
is spelled correctly, the result will be empty.
## Properties
### `webFrame.top` _Readonly_
A `WebFrame | null` representing top frame in frame hierarchy to which `webFrame`
belongs, the property would be `null` if top frame is not in the current
renderer process.
### `webFrame.opener` _Readonly_
A `WebFrame | null` representing the frame which opened `webFrame`, the property would
be `null` if there's no opener or opener is not in the current renderer process.
### `webFrame.parent` _Readonly_
A `WebFrame | null` representing parent frame of `webFrame`, the property would be
`null` if `webFrame` is top or parent is not in the current renderer process.
### `webFrame.firstChild` _Readonly_
A `WebFrame | null` representing the first child frame of `webFrame`, the property
would be `null` if `webFrame` has no children or if first child is not in the
current renderer process.
### `webFrame.nextSibling` _Readonly_
A `WebFrame | null` representing next sibling frame, the property would be `null` if
`webFrame` is the last frame in its parent or if the next sibling is not in the
current renderer process.
### `webFrame.routingId` _Readonly_
An `Integer` representing the unique frame id in the current renderer process.
Distinct WebFrame instances that refer to the same underlying frame will have
the same `routingId`.

[Bug]: BrowserWindow.getFocusedWindow crash: Cannot read properties of null (reading 'isDevToolsFocused')
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
17.1.0, at least back to 12.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
A function like `BrowserWindow.getFocusedWindow()` shouldn't crash if a window is destroyed.
### Actual Behavior
`BrowserWindow.getFocusedWindow()` sometimes crashes
### Testcase Gist URL
https://gist.github.com/d7433e132a56679832f37a9446d4530c
### Additional Information
Stack:
```
TypeError: Cannot read properties of null (reading 'isDevToolsFocused')
at BrowserWindow.n.isDevToolsFocused (node:electron/js2c/browser_init:33:2385)
at Function.n.getFocusedWindow (node:electron/js2c/browser_init:33:1508)
```
Should we have some `isDestroyed()` check here:
https://github.com/electron/electron/blob/44491b023ac2653538b7ac36bb73f3085a938666/lib/browser/api/browser-window.ts#L73-L78
Another option is for `getAllWindows()` to stop returning the destroyed window? (or I guess all we really know is that the window doesn't have a `webContents`).
1. Run the gist above
2. click the open window button (this will open a window and then create a second one that's a child of the first)
3. click the destroy window button
4. Observe the crash popup
So specific to cases where a parent window is closed, and the child window's `closed` handler is calling `BrowserWindow.getFocusedWindow()`

[Bug]: BrowserWindow.getFocusedWindow crash: Cannot read properties of null (reading 'isDevToolsFocused')
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
17.1.0, at least back to 12.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
A function like `BrowserWindow.getFocusedWindow()` shouldn't crash if a window is destroyed.
### Actual Behavior
`BrowserWindow.getFocusedWindow()` sometimes crashes
### Testcase Gist URL
https://gist.github.com/d7433e132a56679832f37a9446d4530c
### Additional Information
Stack:
```
TypeError: Cannot read properties of null (reading 'isDevToolsFocused')
at BrowserWindow.n.isDevToolsFocused (node:electron/js2c/browser_init:33:2385)
at Function.n.getFocusedWindow (node:electron/js2c/browser_init:33:1508)
```
Should we have some `isDestroyed()` check here:
https://github.com/electron/electron/blob/44491b023ac2653538b7ac36bb73f3085a938666/lib/browser/api/browser-window.ts#L73-L78
Another option is for `getAllWindows()` to stop returning the destroyed window? (or I guess all we really know is that the window doesn't have a `webContents`).
1. Run the gist above
2. click the open window button (this will open a window and then create a second one that's a child of the first)
3. click the destroy window button
4. Observe the crash popup
So specific to cases where a parent window is closed, and the child window's `closed` handler is calling `BrowserWindow.getFocusedWindow()`

[Bug]: BrowserWindow.getFocusedWindow crash: Cannot read properties of null (reading 'isDevToolsFocused')
|
### Preflight Checklist

- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
17.1.0, at least back to 12.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
A function like `BrowserWindow.getFocusedWindow()` shouldn't crash if a window is destroyed.
### Actual Behavior
`BrowserWindow.getFocusedWindow()` sometimes crashes
### Testcase Gist URL
https://gist.github.com/d7433e132a56679832f37a9446d4530c
### Additional Information
Stack:
```
TypeError: Cannot read properties of null (reading 'isDevToolsFocused')
at BrowserWindow.n.isDevToolsFocused (node:electron/js2c/browser_init:33:2385)
at Function.n.getFocusedWindow (node:electron/js2c/browser_init:33:1508)
```
Should we have some `isDestroyed()` check here:
https://github.com/electron/electron/blob/44491b023ac2653538b7ac36bb73f3085a938666/lib/browser/api/browser-window.ts#L73-L78
Another option is for `getAllWindows()` to stop returning the destroyed window? (or I guess all we really know is that the window doesn't have a `webContents`).
1. Run the gist above
2. click the open window button (this will open a window and then create a second one that's a child of the first)
3. click the destroy window button
4. Observe the crash popup
So specific to cases where a parent window is closed, and the child window's `closed` handler is calling `BrowserWindow.getFocusedWindow()`

[Bug]: Full Height BrowserWindow Unmaximizes to Bottom Left of Screen
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
19.0.0-nightly.20220317
### What operating system are you using?
macOS
### Operating System Version
macOS 12.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
None
### Expected Behavior
A `BrowserWindow` created with full screen height either shouldn't unmaximize, or should unmaximize to a reasonable size.
### Actual Behavior
A `BrowserWindow` created with full screen height unmaximizes down to the bottom left corner of the screen and size 1x29.
### Testcase Gist URL
https://gist.github.com/098b4bd24638518f9c973ff144b8dd79
### Additional Information
So far only tested on macOS.

[Bug]: Full Height BrowserWindow Unmaximizes to Bottom Left of Screen
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
19.0.0-nightly.20220317
### What operating system are you using?
macOS
### Operating System Version
macOS 12.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
None
### Expected Behavior
A `BrowserWindow` created with full screen height either shouldn't unmaximize, or should unmaximize to a reasonable size.
### Actual Behavior
A `BrowserWindow` created with full screen height unmaximizes down to the bottom left corner of the screen and size 1x29.
### Testcase Gist URL
https://gist.github.com/098b4bd24638518f9c973ff144b8dd79
### Additional Information
So far only tested on macOS.

[Bug]: Full Height BrowserWindow Unmaximizes to Bottom Left of Screen
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
19.0.0-nightly.20220317
### What operating system are you using?
macOS
### Operating System Version
macOS 12.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
None
### Expected Behavior
A `BrowserWindow` created with full screen height either shouldn't unmaximize, or should unmaximize to a reasonable size.
### Actual Behavior
A `BrowserWindow` created with full screen height unmaximizes down to the bottom left corner of the screen and size 1x29.
### Testcase Gist URL
https://gist.github.com/098b4bd24638518f9c973ff144b8dd79
### Additional Information
So far only tested on macOS.

[Bug]: Full Height BrowserWindow Unmaximizes to Bottom Left of Screen
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
19.0.0-nightly.20220317
### What operating system are you using?
macOS
### Operating System Version
macOS 12.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
None
### Expected Behavior
A `BrowserWindow` created with full screen height either shouldn't unmaximize, or should unmaximize to a reasonable size.
### Actual Behavior
A `BrowserWindow` created with full screen height unmaximizes down to the bottom left corner of the screen and size 1x29.
### Testcase Gist URL
https://gist.github.com/098b4bd24638518f9c973ff144b8dd79
### Additional Information
So far only tested on macOS.

[Bug]: Full Height BrowserWindow Unmaximizes to Bottom Left of Screen
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
19.0.0-nightly.20220317
### What operating system are you using?
macOS
### Operating System Version
macOS 12.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
None
### Expected Behavior
A `BrowserWindow` created with full screen height either shouldn't unmaximize, or should unmaximize to a reasonable size.
### Actual Behavior
A `BrowserWindow` created with full screen height unmaximizes down to the bottom left corner of the screen and size 1x29.
### Testcase Gist URL
https://gist.github.com/098b4bd24638518f9c973ff144b8dd79
### Additional Information
So far only tested on macOS.

[Bug]: Full Height BrowserWindow Unmaximizes to Bottom Left of Screen
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
19.0.0-nightly.20220317
### What operating system are you using?
macOS
### Operating System Version
macOS 12.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
None
### Expected Behavior
A `BrowserWindow` created with full screen height either shouldn't unmaximize, or should unmaximize to a reasonable size.
### Actual Behavior
A `BrowserWindow` created with full screen height unmaximizes down to the bottom left corner of the screen and size 1x29.
### Testcase Gist URL
https://gist.github.com/098b4bd24638518f9c973ff144b8dd79
### Additional Information
So far only tested on macOS.

[Bug]: `app.requestSingleInstanceLock()` returns false on first start
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
17.3.1, also affected: 16, 17, 18, 19, 20
### What operating system are you using?
macOS
### Operating System Version
12.3, also affected: Win, Linux
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app should return `true`.
### Actual Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app returns `false`.
### Testcase Gist URL
https://gist.github.com/6d51100568b78f98c5177cb27d370f9f
### Additional Information
It seems that the issue only exists when setting the `userData` path to a non-existent folder (which is most likely the case when you start the app for the first time on a fresh computer). Subsequent starts result in correct behavior because the folder has been created by then. The issue was not present in E15 and below; I'll bisect further.
The issue becomes problematic when implementing a behavior as described [in the docs](https://www.electronjs.org/docs/latest/api/app#apprequestsingleinstancelockadditionaldata) because the app will just quit on first start:
```js
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {...
```

[Bug]: `app.requestSingleInstanceLock()` returns false on first start
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
17.3.1, also affected: 16, 17, 18, 19, 20
### What operating system are you using?
macOS
### Operating System Version
12.3, also affected: Win, Linux
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app should return `true`.
### Actual Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app returns `false`.
### Testcase Gist URL
https://gist.github.com/6d51100568b78f98c5177cb27d370f9f
### Additional Information
It seems that the issue only exists when setting the `userData` path to a non-existent folder (which is most likely the case when you start the app for the first time on a fresh computer). Subsequent starts result in correct behavior because the folder has been created by then. The issue was not present in E15 and below; I'll bisect further.
The issue becomes problematic when implementing a behavior as described [in the docs](https://www.electronjs.org/docs/latest/api/app#apprequestsingleinstancelockadditionaldata) because the app will just quit on first start:
```js
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {...
```

_funfact: this was a pain to debug since it crashed our CI in a very obscure way 😆_

[Bug]: `app.requestSingleInstanceLock()` returns false on first start

### Preflight Checklist

### Electron Version
17.3.1, also affected: 16, 17, 18, 19, 20
### What operating system are you using?
macOS
### Operating System Version
12.3, also affected: Win, Linux
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app should return `true`.
### Actual Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app returns `false`.
### Testcase Gist URL
https://gist.github.com/6d51100568b78f98c5177cb27d370f9f
### Additional Information
It seems that the issue only exists when setting the `userData` path to a non-existent folder (which is most likely the case when you start the app for the first time on a fresh computer). Subsequent starts result in correct behavior because the folder has been created by then. The issue was not present in E15 and below; I'll bisect further.
The issue becomes problematic when implementing a behavior as described [in the docs](https://www.electronjs.org/docs/latest/api/app#apprequestsingleinstancelockadditionaldata) because the app will just quit on first start:
```js
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {...
```

[Bug]: `app.requestSingleInstanceLock()` returns false on first start
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
17.3.1, also affected: 16, 17, 18, 19, 20
### What operating system are you using?
macOS
### Operating System Version
12.3, also affected: Win, Linux
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app should return `true`.
### Actual Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app returns `false`.
### Testcase Gist URL
https://gist.github.com/6d51100568b78f98c5177cb27d370f9f
### Additional Information
It seems that the issue only exists when setting the `userData` path to a non-existent folder (which is most likely the case when you start the app for the first time on a fresh computer). Subsequent starts result in correct behavior because the folder has been created by then. The issue was not present in E15 and below; I'll bisect further.
The issue becomes problematic when implementing a behavior as described [in the docs](https://www.electronjs.org/docs/latest/api/app#apprequestsingleinstancelockadditionaldata) because the app will just quit on first start:
```js
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {...
```

[Bug]: `app.requestSingleInstanceLock()` returns false on first start

### Preflight Checklist

- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
17.3.1, also affected: 16, 17, 18, 19, 20
### What operating system are you using?
macOS
### Operating System Version
12.3, also affected: Win, Linux
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app should return `true`.
### Actual Behavior
Requesting `app.requestSingleInstanceLock()` on first start of the app returns `false`.
### Testcase Gist URL
https://gist.github.com/6d51100568b78f98c5177cb27d370f9f
### Additional Information
It seems that the issue only exists when setting the `userData` path to a non-existent folder (which is most likely the case when you start the app for the first time on a fresh computer). Subsequent starts result in correct behavior because the folder has been created by then. The issue was not present in E15 and below; I'll bisect further.
The issue becomes problematic when implementing a behavior as described [in the docs](https://www.electronjs.org/docs/latest/api/app#apprequestsingleinstancelockadditionaldata) because the app will just quit on first start:
```js
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {...
```

### Electron Version
18.0.1
### Rejection Email
Hello,
Thank you for submitting your items for review. We noticed an issue with your submission that requires your attention.
> Guideline 2.5.1 - Performance - Software Requirements
>
>
>
> Your app uses or references the following non-public or deprecated APIs:
>
> Info
> • Contents/Frameworks/Electron Framework.framework/Versions/A/Electron Framework/_responsibility_get_pid_responsible_for_pid
>
> The use of non-public or deprecated APIs is not permitted on the App Store, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms.
>
> Next Steps
>
> It would be appropriate to revise your binary and remove any references to the non-public or deprecated APIs identified above.
>
> If you are using third-party libraries, update to the most recent version of those libraries. If you do not have access to the libraries' source, the following command line tools can help you identify the location of problematic code:
> - The "strings" tool can output a list of the methods the library calls.
> - The "otool -ov" tool will output the Objective-C class structures and their defined methods.
>
> Resources
>
> - We are constantly reevaluating and identifying non-public APIs that you may have been using for an extended period of time. Always use [public APIs and frameworks](https://developer.apple.com/documentation/) and ensure they are up to date.
> - If there are no alternatives for providing the functionality your app requires, you can use [Feedback Assistant](https://feedbackassistant.apple.com/welcome) to submit an enhancement request.
>

[MAS Rejection]: non-public or deprecated APIs _responsibility_get_pid_responsible_for_pid
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
### Electron Version
18.0.1
### Rejection Email
Hello,
Thank you for submitting your items for review. We noticed an issue with your submission that requires your attention.
> Guideline 2.5.1 - Performance - Software Requirements
>
>
>
> Your app uses or references the following non-public or deprecated APIs:
>
> Info
> • Contents/Frameworks/Electron Framework.framework/Versions/A/Electron Framework/_responsibility_get_pid_responsible_for_pid
>
> The use of non-public or deprecated APIs is not permitted on the App Store, as they can lead to a poor user experience should these APIs change and are otherwise not supported on Apple platforms.
>
> Next Steps
>
> It would be appropriate to revise your binary and remove any references to the non-public or deprecated APIs identified above.
>
> If you are using third-party libraries, update to the most recent version of those libraries. If you do not have access to the libraries' source, the following command line tools can help you identify the location of problematic code:
> - The "strings" tool can output a list of the methods the library calls.
> - The "otool -ov" tool will output the Objective-C class structures and their defined methods.
>
> Resources
>
> - We are constantly reevaluating and identifying non-public APIs that you may have been using for an extended period of time. Always use [public APIs and frameworks](https://developer.apple.com/documentation/) and ensure they are up to date.
> - If there are no alternatives for providing the functionality your app requires, you can use [Feedback Assistant](https://feedbackassistant.apple.com/welcome) to submit an enhancement request.
>

[Documentation] browserWindow event.returnValue contradiction
|
### Documentation Issue
Please see this commit https://github.com/electron/electron/commit/bb153ee79e6bb4e54d4d075f64a448f498fbeff8 which, without explanation, says that it is both _recommended_ **and** _not recommended_ to set the event.returnValue directly.
Is it possible to disambiguate this or provide a further explanation for the comment?

# BrowserWindow
> Create and control browser windows.
Process: [Main](../glossary.md#main-process)
```javascript
// In the main process.
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
// Load a remote URL
win.loadURL('https://github.com')
// Or load a local HTML file
win.loadFile('index.html')
```
## Window customization
The `BrowserWindow` class exposes various ways to modify the look and behavior of
your app's windows. For more details, see the [Window Customization](../tutorial/window-customization.md)
tutorial.
## Showing the window gracefully
When loading a page in the window directly, users may see the page load incrementally,
which is not a good experience for a native app. To make the window display
without a visual flash, there are two solutions for different situations.
### Using the `ready-to-show` event
While loading the page, the `ready-to-show` event will be emitted when the renderer
process has rendered the page for the first time if the window has not been shown yet. Showing
the window after this event will have no visual flash:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ show: false })
win.once('ready-to-show', () => {
win.show()
})
```
This event is usually emitted after the `did-finish-load` event, but for
pages with many remote resources, it may be emitted before the `did-finish-load`
event.
Please note that using this event implies that the renderer will be considered "visible" and
paint even though `show` is false. This event will never fire if you use `paintWhenInitiallyHidden: false`
### Setting the `backgroundColor` property
For a complex app, the `ready-to-show` event could be emitted too late, making
the app feel slow. In this case, it is recommended to show the window
immediately, and use a `backgroundColor` close to your app's background:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ backgroundColor: '#2e2c29' })
win.loadURL('https://github.com')
```
Note that even for apps that use `ready-to-show` event, it is still recommended
to set `backgroundColor` to make the app feel more native.
Some examples of valid `backgroundColor` values include:
```js
const win = new BrowserWindow()
win.setBackgroundColor('hsl(230, 100%, 50%)')
win.setBackgroundColor('rgb(255, 145, 145)')
win.setBackgroundColor('#ff00a3')
win.setBackgroundColor('blueviolet')
```
For more information about these color types see valid options in [win.setBackgroundColor](browser-window.md#winsetbackgroundcolorbackgroundcolor).
## Parent and child windows
By using `parent` option, you can create child windows:
```javascript
const { BrowserWindow } = require('electron')
const top = new BrowserWindow()
const child = new BrowserWindow({ parent: top })
child.show()
top.show()
```
The `child` window will always show on top of the `top` window.
## Modal windows
A modal window is a child window that disables parent window, to create a modal
window, you have to set both `parent` and `modal` options:
```javascript
const { BrowserWindow } = require('electron')
const child = new BrowserWindow({ parent: top, modal: true, show: false })
child.loadURL('https://github.com')
child.once('ready-to-show', () => {
child.show()
})
```
## Page visibility
The [Page Visibility API][page-visibility-api] works as follows:
* On all platforms, the visibility state tracks whether the window is
hidden/minimized or not.
* Additionally, on macOS, the visibility state also tracks the window
occlusion state. If the window is occluded (i.e. fully covered) by another
window, the visibility state will be `hidden`. On other platforms, the
visibility state will be `hidden` only when the window is minimized or
explicitly hidden with `win.hide()`.
* If a `BrowserWindow` is created with `show: false`, the initial visibility
state will be `visible` despite the window actually being hidden.
* If `backgroundThrottling` is disabled, the visibility state will remain
`visible` even if the window is minimized, occluded, or hidden.
It is recommended that you pause expensive operations when the visibility
state is `hidden` in order to minimize power consumption.
## Platform notices
* On macOS modal windows will be displayed as sheets attached to the parent window.
* On macOS the child windows will keep the relative position to parent window
when parent window moves, while on Windows and Linux child windows will not
move.
* On Linux the type of modal windows will be changed to `dialog`.
* On Linux many desktop environments do not support hiding a modal window.
## Class: BrowserWindow
> Create and control browser windows.
Process: [Main](../glossary.md#main-process)
`BrowserWindow` is an [EventEmitter][event-emitter].
It creates a new `BrowserWindow` with native properties as set by the `options`.
### `new BrowserWindow([options])`
* `options` Object (optional)
* `width` Integer (optional) - Window's width in pixels. Default is `800`.
* `height` Integer (optional) - Window's height in pixels. Default is `600`.
* `x` Integer (optional) - (**required** if y is used) Window's left offset from screen.
Default is to center the window.
* `y` Integer (optional) - (**required** if x is used) Window's top offset from screen.
Default is to center the window.
* `useContentSize` boolean (optional) - The `width` and `height` would be used as web
page's size, which means the actual window's size will include window
frame's size and be slightly larger. Default is `false`.
* `center` boolean (optional) - Show window in the center of the screen. Default is `false`.
* `minWidth` Integer (optional) - Window's minimum width. Default is `0`.
* `minHeight` Integer (optional) - Window's minimum height. Default is `0`.
* `maxWidth` Integer (optional) - Window's maximum width. Default is no limit.
* `maxHeight` Integer (optional) - Window's maximum height. Default is no limit.
* `resizable` boolean (optional) - Whether window is resizable. Default is `true`.
* `movable` boolean (optional) _macOS_ _Windows_ - Whether window is
movable. This is not implemented on Linux. Default is `true`.
* `minimizable` boolean (optional) _macOS_ _Windows_ - Whether window is
minimizable. This is not implemented on Linux. Default is `true`.
* `maximizable` boolean (optional) _macOS_ _Windows_ - Whether window is
maximizable. This is not implemented on Linux. Default is `true`.
* `closable` boolean (optional) _macOS_ _Windows_ - Whether window is
closable. This is not implemented on Linux. Default is `true`.
* `focusable` boolean (optional) - Whether the window can be focused. Default is
`true`. On Windows setting `focusable: false` also implies setting
`skipTaskbar: true`. On Linux setting `focusable: false` makes the window
stop interacting with wm, so the window will always stay on top in all
workspaces.
* `alwaysOnTop` boolean (optional) - Whether the window should always stay on top of
other windows. Default is `false`.
* `fullscreen` boolean (optional) - Whether the window should show in fullscreen. When
explicitly set to `false` the fullscreen button will be hidden or disabled
on macOS. Default is `false`.
* `fullscreenable` boolean (optional) - Whether the window can be put into fullscreen
mode. On macOS, also whether the maximize/zoom button should toggle full
screen mode or maximize window. Default is `true`.
* `simpleFullscreen` boolean (optional) _macOS_ - Use pre-Lion fullscreen on
macOS. Default is `false`.
* `skipTaskbar` boolean (optional) _macOS_ _Windows_ - Whether to show the window in taskbar.
Default is `false`.
* `kiosk` boolean (optional) - Whether the window is in kiosk mode. Default is `false`.
* `title` string (optional) - Default window title. Default is `"Electron"`. If the HTML tag `<title>` is defined in the HTML file loaded by `loadURL()`, this property will be ignored.
* `icon` ([NativeImage](native-image.md) | string) (optional) - The window icon. On Windows it is
recommended to use `ICO` icons to get best visual effects, you can also
leave it undefined so the executable's icon will be used.
* `show` boolean (optional) - Whether window should be shown when created. Default is
`true`.
* `paintWhenInitiallyHidden` boolean (optional) - Whether the renderer should be active when `show` is `false` and it has just been created. In order for `document.visibilityState` to work correctly on first load with `show: false` you should set this to `false`. Setting this to `false` will cause the `ready-to-show` event to not fire. Default is `true`.
* `frame` boolean (optional) - Specify `false` to create a
[frameless window](../tutorial/window-customization.md#create-frameless-windows). Default is `true`.
* `parent` BrowserWindow (optional) - Specify parent window. Default is `null`.
* `modal` boolean (optional) - Whether this is a modal window. This only works when the
window is a child window. Default is `false`.
* `acceptFirstMouse` boolean (optional) _macOS_ - Whether clicking an
inactive window will also click through to the web contents. Default is
`false` on macOS. This option is not configurable on other platforms.
* `disableAutoHideCursor` boolean (optional) - Whether to hide cursor when typing.
Default is `false`.
* `autoHideMenuBar` boolean (optional) - Auto hide the menu bar unless the `Alt`
key is pressed. Default is `false`.
* `enableLargerThanScreen` boolean (optional) _macOS_ - Enable the window to
be resized larger than screen. Only relevant for macOS, as other OSes
allow larger-than-screen windows by default. Default is `false`.
* `backgroundColor` string (optional) - The window's background color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. Alpha in #AARRGGBB format is supported if `transparent` is set to `true`. Default is `#FFF` (white). See [win.setBackgroundColor](browser-window.md#winsetbackgroundcolorbackgroundcolor) for more information.
* `hasShadow` boolean (optional) - Whether window should have a shadow. Default is `true`.
* `opacity` number (optional) _macOS_ _Windows_ - Set the initial opacity of
the window, between 0.0 (fully transparent) and 1.0 (fully opaque). This
is only implemented on Windows and macOS.
* `darkTheme` boolean (optional) - Forces using dark theme for the window, only works on
some GTK+3 desktop environments. Default is `false`.
* `transparent` boolean (optional) - Makes the window [transparent](../tutorial/window-customization.md#create-transparent-windows).
Default is `false`. On Windows, does not work unless the window is frameless.
* `type` string (optional) - The type of window, default is normal window. See more about
this below.
* `visualEffectState` string (optional) _macOS_ - Specify how the material
appearance should reflect window activity state on macOS. Must be used
with the `vibrancy` property. Possible values are:
* `followWindow` - The backdrop should automatically appear active when the window is active, and inactive when it is not. This is the default.
* `active` - The backdrop should always appear active.
* `inactive` - The backdrop should always appear inactive.
* `titleBarStyle` string (optional) _macOS_ _Windows_ - The style of window title bar.
Default is `default`. Possible values are:
* `default` - Results in the standard title bar for macOS or Windows respectively.
* `hidden` - Results in a hidden title bar and a full size content window. On macOS, the window still has the standard window controls (“traffic lights”) in the top left. On Windows, when combined with `titleBarOverlay: true` it will activate the Window Controls Overlay (see `titleBarOverlay` for more information), otherwise no window controls will be shown.
* `hiddenInset` _macOS_ - Only on macOS, results in a hidden title bar
with an alternative look where the traffic light buttons are slightly
more inset from the window edge.
* `customButtonsOnHover` _macOS_ - Only on macOS, results in a hidden
title bar and a full size content window, the traffic light buttons will
display when being hovered over in the top left of the window.
**Note:** This option is currently experimental.
* `trafficLightPosition` [Point](structures/point.md) (optional) _macOS_ -
Set a custom position for the traffic light buttons in frameless windows.
* `roundedCorners` boolean (optional) _macOS_ - Whether frameless window
should have rounded corners on macOS. Default is `true`.
* `fullscreenWindowTitle` boolean (optional) _macOS_ _Deprecated_ - Shows
the title in the title bar in full screen mode on macOS for `hiddenInset`
titleBarStyle. Default is `false`.
* `thickFrame` boolean (optional) - Use `WS_THICKFRAME` style for frameless windows on
Windows, which adds standard window frame. Setting it to `false` will remove
window shadow and window animations. Default is `true`.
* `vibrancy` string (optional) _macOS_ - Add a type of vibrancy effect to
the window, only on macOS. Can be `appearance-based`, `light`, `dark`,
`titlebar`, `selection`, `menu`, `popover`, `sidebar`, `medium-light`,
`ultra-dark`, `header`, `sheet`, `window`, `hud`, `fullscreen-ui`,
`tooltip`, `content`, `under-window`, or `under-page`. Please note that
`appearance-based`, `light`, `dark`, `medium-light`, and `ultra-dark` are
deprecated and have been removed in macOS Catalina (10.15).
* `zoomToPageWidth` boolean (optional) _macOS_ - Controls the behavior on
macOS when option-clicking the green stoplight button on the toolbar or by
clicking the Window > Zoom menu item. If `true`, the window will grow to
the preferred width of the web page when zoomed, `false` will cause it to
zoom to the width of the screen. This will also affect the behavior when
calling `maximize()` directly. Default is `false`.
* `tabbingIdentifier` string (optional) _macOS_ - Tab group name, allows
opening the window as a native tab on macOS 10.12+. Windows with the same
tabbing identifier will be grouped together. This also adds a native new
tab button to your window's tab bar and allows your `app` and window to
receive the `new-window-for-tab` event.
* `webPreferences` Object (optional) - Settings of web page's features.
* `devTools` boolean (optional) - Whether to enable DevTools. If it is set to `false`, can not use `BrowserWindow.webContents.openDevTools()` to open DevTools. Default is `true`.
* `nodeIntegration` boolean (optional) - Whether node integration is enabled.
Default is `false`.
* `nodeIntegrationInWorker` boolean (optional) - Whether node integration is
enabled in web workers. Default is `false`. More about this can be found
in [Multithreading](../tutorial/multithreading.md).
* `nodeIntegrationInSubFrames` boolean (optional) - Experimental option for
enabling Node.js support in sub-frames such as iframes and child windows. All your preloads will load for
every iframe, you can use `process.isMainFrame` to determine if you are
in the main frame or not.
* `preload` string (optional) - Specifies a script that will be loaded before other
scripts run in the page. This script will always have access to node APIs
no matter whether node integration is turned on or off. The value should
be the absolute file path to the script.
When node integration is turned off, the preload script can reintroduce
Node global symbols back to the global scope. See example
[here](context-bridge.md#exposing-node-global-symbols).
* `sandbox` boolean (optional) - If set, this will sandbox the renderer
associated with the window, making it compatible with the Chromium
OS-level sandbox and disabling the Node.js engine. This is not the same as
the `nodeIntegration` option and the APIs available to the preload script
are more limited. Read more about the option [here](../tutorial/sandbox.md).
* `session` [Session](session.md#class-session) (optional) - Sets the session used by the
page. Instead of passing the Session object directly, you can also choose to
use the `partition` option instead, which accepts a partition string. When
both `session` and `partition` are provided, `session` will be preferred.
Default is the default session.
* `partition` string (optional) - Sets the session used by the page according to the
session's partition string. If `partition` starts with `persist:`, the page
will use a persistent session available to all pages in the app with the
same `partition`. If there is no `persist:` prefix, the page will use an
in-memory session. By assigning the same `partition`, multiple pages can share
the same session. Default is the default session.
* `zoomFactor` number (optional) - The default zoom factor of the page, `3.0` represents
`300%`. Default is `1.0`.
* `javascript` boolean (optional) - Enables JavaScript support. Default is `true`.
* `webSecurity` boolean (optional) - When `false`, it will disable the
same-origin policy (usually using testing websites by people), and set
`allowRunningInsecureContent` to `true` if this options has not been set
by user. Default is `true`.
* `allowRunningInsecureContent` boolean (optional) - Allow an https page to run
JavaScript, CSS or plugins from http URLs. Default is `false`.
* `images` boolean (optional) - Enables image support. Default is `true`.
* `imageAnimationPolicy` string (optional) - Specifies how to run image animations (E.g. GIFs). Can be `animate`, `animateOnce` or `noAnimation`. Default is `animate`.
* `textAreasAreResizable` boolean (optional) - Make TextArea elements resizable. Default
is `true`.
* `webgl` boolean (optional) - Enables WebGL support. Default is `true`.
* `plugins` boolean (optional) - Whether plugins should be enabled. Default is `false`.
* `experimentalFeatures` boolean (optional) - Enables Chromium's experimental features.
Default is `false`.
* `scrollBounce` boolean (optional) _macOS_ - Enables scroll bounce
(rubber banding) effect on macOS. Default is `false`.
* `enableBlinkFeatures` string (optional) - A list of feature strings separated by `,`, like
`CSSVariables,KeyboardEventKey` to enable. The full list of supported feature
strings can be found in the [RuntimeEnabledFeatures.json5][runtime-enabled-features]
file.
* `disableBlinkFeatures` string (optional) - A list of feature strings separated by `,`,
like `CSSVariables,KeyboardEventKey` to disable. The full list of supported
feature strings can be found in the
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
* `defaultFontFamily` Object (optional) - Sets the default font for the font-family.
* `standard` string (optional) - Defaults to `Times New Roman`.
* `serif` string (optional) - Defaults to `Times New Roman`.
* `sansSerif` string (optional) - Defaults to `Arial`.
* `monospace` string (optional) - Defaults to `Courier New`.
* `cursive` string (optional) - Defaults to `Script`.
* `fantasy` string (optional) - Defaults to `Impact`.
* `defaultFontSize` Integer (optional) - Defaults to `16`.
* `defaultMonospaceFontSize` Integer (optional) - Defaults to `13`.
* `minimumFontSize` Integer (optional) - Defaults to `0`.
* `defaultEncoding` string (optional) - Defaults to `ISO-8859-1`.
* `backgroundThrottling` boolean (optional) - Whether to throttle animations and timers
when the page becomes background. This also affects the
[Page Visibility API](#page-visibility). Defaults to `true`.
* `offscreen` boolean (optional) - Whether to enable offscreen rendering for the browser
window. Defaults to `false`. See the
[offscreen rendering tutorial](../tutorial/offscreen-rendering.md) for
more details.
* `contextIsolation` boolean (optional) - Whether to run Electron APIs and
the specified `preload` script in a separate JavaScript context. Defaults
to `true`. The context that the `preload` script runs in will only have
access to its own dedicated `document` and `window` globals, as well as
its own set of JavaScript builtins (`Array`, `Object`, `JSON`, etc.),
which are all invisible to the loaded content. The Electron API will only
be available in the `preload` script and not the loaded page. This option
should be used when loading potentially untrusted remote content to ensure
the loaded content cannot tamper with the `preload` script and any
Electron APIs being used. This option uses the same technique used by
[Chrome Content Scripts][chrome-content-scripts]. You can access this
context in the dev tools by selecting the 'Electron Isolated Context'
entry in the combo box at the top of the Console tab.
* `webviewTag` boolean (optional) - Whether to enable the [`<webview>` tag](webview-tag.md).
Defaults to `false`. **Note:** The
`preload` script configured for the `<webview>` will have node integration
enabled when it is executed so you should ensure remote/untrusted content
is not able to create a `<webview>` tag with a possibly malicious `preload`
script. You can use the `will-attach-webview` event on [webContents](web-contents.md)
to strip away the `preload` script and to validate or alter the
`<webview>`'s initial settings.
* `additionalArguments` string[] (optional) - A list of strings that will be appended
to `process.argv` in the renderer process of this app. Useful for passing small
bits of data down to renderer process preload scripts.
* `safeDialogs` boolean (optional) - Whether to enable browser style
consecutive dialog protection. Default is `false`.
* `safeDialogsMessage` string (optional) - The message to display when
consecutive dialog protection is triggered. If not defined the default
message would be used, note that currently the default message is in
English and not localized.
* `disableDialogs` boolean (optional) - Whether to disable dialogs
completely. Overrides `safeDialogs`. Default is `false`.
* `navigateOnDragDrop` boolean (optional) - Whether dragging and dropping a
file or link onto the page causes a navigation. Default is `false`.
* `autoplayPolicy` string (optional) - Autoplay policy to apply to
content in the window, can be `no-user-gesture-required`,
`user-gesture-required`, `document-user-activation-required`. Defaults to
`no-user-gesture-required`.
* `disableHtmlFullscreenWindowResize` boolean (optional) - Whether to
prevent the window from resizing when entering HTML Fullscreen. Default
is `false`.
* `accessibleTitle` string (optional) - An alternative title string provided only
to accessibility tools such as screen readers. This string is not directly
visible to users.
* `spellcheck` boolean (optional) - Whether to enable the builtin spellchecker.
Default is `true`.
* `enableWebSQL` boolean (optional) - Whether to enable the [WebSQL api](https://www.w3.org/TR/webdatabase/).
Default is `true`.
* `v8CacheOptions` string (optional) - Enforces the v8 code caching policy
used by blink. Accepted values are
* `none` - Disables code caching
* `code` - Heuristic based code caching
* `bypassHeatCheck` - Bypass code caching heuristics but with lazy compilation
* `bypassHeatCheckAndEagerCompile` - Same as above except compilation is eager.
Default policy is `code`.
* `enablePreferredSizeMode` boolean (optional) - Whether to enable
preferred size mode. The preferred size is the minimum size needed to
contain the layout of the document—without requiring scrolling. Enabling
this will cause the `preferred-size-changed` event to be emitted on the
`WebContents` when the preferred size changes. Default is `false`.
* `titleBarOverlay` Object | Boolean (optional) - When using a frameless window in conjunction with `win.setWindowButtonVisibility(true)` on macOS or using a `titleBarStyle` so that the standard window controls ("traffic lights" on macOS) are visible, this property enables the Window Controls Overlay [JavaScript APIs][overlay-javascript-apis] and [CSS Environment Variables][overlay-css-env-vars]. Specifying `true` will result in an overlay with default system colors. Default is `false`.
* `color` String (optional) _Windows_ - The CSS color of the Window Controls Overlay when enabled. Default is the system color.
* `symbolColor` String (optional) _Windows_ - The CSS color of the symbols on the Window Controls Overlay when enabled. Default is the system color.
* `height` Integer (optional) _macOS_ _Windows_ - The height of the title bar and Window Controls Overlay in pixels. Default is system height.
When setting minimum or maximum window size with `minWidth`/`maxWidth`/
`minHeight`/`maxHeight`, it only constrains the users. It won't prevent you from
passing a size that does not follow size constraints to `setBounds`/`setSize` or
to the constructor of `BrowserWindow`.
The possible values and behaviors of the `type` option are platform dependent.
Possible values are:
* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
`notification`.
* On macOS, possible types are `desktop`, `textured`.
* The `textured` type adds metal gradient appearance
(`NSTexturedBackgroundWindowMask`).
* The `desktop` type places the window at the desktop background window level
(`kCGDesktopWindowLevel - 1`). Note that desktop window will not receive
focus, keyboard or mouse events, but you can use `globalShortcut` to receive
input sparingly.
* On Windows, possible type is `toolbar`.
### Instance Events
Objects created with `new BrowserWindow` emit the following events:
**Note:** Some events are only available on specific operating systems and are
labeled as such.
#### Event: 'page-title-updated'
Returns:
* `event` Event
* `title` string
* `explicitSet` boolean
Emitted when the document changed its title, calling `event.preventDefault()`
will prevent the native window's title from changing.
`explicitSet` is false when title is synthesized from file URL.
#### Event: 'close'
Returns:
* `event` Event
Emitted when the window is going to be closed. It's emitted before the
`beforeunload` and `unload` event of the DOM. Calling `event.preventDefault()`
will cancel the close.
Usually you would want to use the `beforeunload` handler to decide whether the
window should be closed, which will also be called when the window is
reloaded. In Electron, returning any value other than `undefined` would cancel the
close. For example:
```javascript
window.onbeforeunload = (e) => {
console.log('I do not want to be closed')
// Unlike usual browsers that a message box will be prompted to users, returning
// a non-void value will silently cancel the close.
// It is recommended to use the dialog API to let the user confirm closing the
// application.
e.returnValue = false // equivalent to `return false` but not recommended
}
```
_**Note**: There is a subtle difference between the behaviors of `window.onbeforeunload = handler` and `window.addEventListener('beforeunload', handler)`. It is recommended to always set the `event.returnValue` explicitly, instead of only returning a value, as the former works more consistently within Electron._
#### Event: 'closed'
Emitted when the window is closed. After you have received this event you should
remove the reference to the window and avoid using it any more.
#### Event: 'session-end' _Windows_
Emitted when window session is going to end due to force shutdown or machine restart
or session log off.
#### Event: 'unresponsive'
Emitted when the web page becomes unresponsive.
#### Event: 'responsive'
Emitted when the unresponsive web page becomes responsive again.
#### Event: 'blur'
Emitted when the window loses focus.
#### Event: 'focus'
Emitted when the window gains focus.
#### Event: 'show'
Emitted when the window is shown.
#### Event: 'hide'
Emitted when the window is hidden.
#### Event: 'ready-to-show'
Emitted when the web page has been rendered (while not being shown) and window can be displayed without
a visual flash.
Please note that using this event implies that the renderer will be considered "visible" and
paint even though `show` is false. This event will never fire if you use `paintWhenInitiallyHidden: false`
#### Event: 'maximize'
Emitted when window is maximized.
#### Event: 'unmaximize'
Emitted when the window exits from a maximized state.
#### Event: 'minimize'
Emitted when the window is minimized.
#### Event: 'restore'
Emitted when the window is restored from a minimized state.
#### Event: 'will-resize' _macOS_ _Windows_
Returns:
* `event` Event
* `newBounds` [Rectangle](structures/rectangle.md) - Size the window is being resized to.
* `details` Object
* `edge` (string) - The edge of the window being dragged for resizing. Can be `bottom`, `left`, `right`, `top-left`, `top-right`, `bottom-left` or `bottom-right`.
Emitted before the window is resized. Calling `event.preventDefault()` will prevent the window from being resized.
Note that this is only emitted when the window is being resized manually. Resizing the window with `setBounds`/`setSize` will not emit this event.
The possible values and behaviors of the `edge` option are platform dependent. Possible values are:
* On Windows, possible values are `bottom`, `top`, `left`, `right`, `top-left`, `top-right`, `bottom-left`, `bottom-right`.
* On macOS, possible values are `bottom` and `right`.
* The value `bottom` is used to denote vertical resizing.
* The value `right` is used to denote horizontal resizing.
#### Event: 'resize'
Emitted after the window has been resized.
#### Event: 'resized' _macOS_ _Windows_
Emitted once when the window has finished being resized.
This is usually emitted when the window has been resized manually. On macOS, resizing the window with `setBounds`/`setSize` and setting the `animate` parameter to `true` will also emit this event once resizing has finished.
#### Event: 'will-move' _macOS_ _Windows_
Returns:
* `event` Event
* `newBounds` [Rectangle](structures/rectangle.md) - Location the window is being moved to.
Emitted before the window is moved. On Windows, calling `event.preventDefault()` will prevent the window from being moved.
Note that this is only emitted when the window is being moved manually. Moving the window with `setPosition`/`setBounds`/`center` will not emit this event.
#### Event: 'move'
Emitted when the window is being moved to a new position.
#### Event: 'moved' _macOS_ _Windows_
Emitted once when the window is moved to a new position.
__Note__: On macOS this event is an alias of `move`.
#### Event: 'enter-full-screen'
Emitted when the window enters a full-screen state.
#### Event: 'leave-full-screen'
Emitted when the window leaves a full-screen state.
#### Event: 'enter-html-full-screen'
Emitted when the window enters a full-screen state triggered by HTML API.
#### Event: 'leave-html-full-screen'
Emitted when the window leaves a full-screen state triggered by HTML API.
#### Event: 'always-on-top-changed'
Returns:
* `event` Event
* `isAlwaysOnTop` boolean
Emitted when the window is set or unset to show always on top of other windows.
#### Event: 'app-command' _Windows_ _Linux_
Returns:
* `event` Event
* `command` string
Emitted when an [App Command](https://msdn.microsoft.com/en-us/library/windows/desktop/ms646275(v=vs.85).aspx)
is invoked. These are typically related to keyboard media keys or browser
commands, as well as the "Back" button built into some mice on Windows.
Commands are lowercased, underscores are replaced with hyphens, and the
`APPCOMMAND_` prefix is stripped off.
e.g. `APPCOMMAND_BROWSER_BACKWARD` is emitted as `browser-backward`.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.on('app-command', (e, cmd) => {
// Navigate the window back when the user hits their mouse back button
if (cmd === 'browser-backward' && win.webContents.canGoBack()) {
win.webContents.goBack()
}
})
```
The following app commands are explicitly supported on Linux:
* `browser-backward`
* `browser-forward`
#### Event: 'scroll-touch-begin' _macOS_
Emitted when scroll wheel event phase has begun.
#### Event: 'scroll-touch-end' _macOS_
Emitted when scroll wheel event phase has ended.
#### Event: 'scroll-touch-edge' _macOS_
Emitted when scroll wheel event phase filed upon reaching the edge of element.
#### Event: 'swipe' _macOS_
Returns:
* `event` Event
* `direction` string
Emitted on 3-finger swipe. Possible directions are `up`, `right`, `down`, `left`.
The method underlying this event is built to handle older macOS-style trackpad swiping,
where the content on the screen doesn't move with the swipe. Most macOS trackpads are not
configured to allow this kind of swiping anymore, so in order for it to emit properly the
'Swipe between pages' preference in `System Preferences > Trackpad > More Gestures` must be
set to 'Swipe with two or three fingers'.
#### Event: 'rotate-gesture' _macOS_
Returns:
* `event` Event
* `rotation` Float
Emitted on trackpad rotation gesture. Continually emitted until rotation gesture is
ended. The `rotation` value on each emission is the angle in degrees rotated since
the last emission. The last emitted event upon a rotation gesture will always be of
value `0`. Counter-clockwise rotation values are positive, while clockwise ones are
negative.
#### Event: 'sheet-begin' _macOS_
Emitted when the window opens a sheet.
#### Event: 'sheet-end' _macOS_
Emitted when the window has closed a sheet.
#### Event: 'new-window-for-tab' _macOS_
Emitted when the native new tab button is clicked.
#### Event: 'system-context-menu' _Windows_
Returns:
* `event` Event
* `point` [Point](structures/point.md) - The screen coordinates the context menu was triggered at
Emitted when the system context menu is triggered on the window, this is
normally only triggered when the user right clicks on the non-client area
of your window. This is the window titlebar or any area you have declared
as `-webkit-app-region: drag` in a frameless window.
Calling `event.preventDefault()` will prevent the menu from being displayed.
### Static Methods

const menu = Menu.buildFromTemplate(template)
Menu.setApplicationMenu(menu)
```
#### `win.accessibleTitle`
A `string` property that defines an alternative title provided only to
accessibility tools such as screen readers. This string is not directly
visible to users.
### Instance Methods
Objects created with `new BrowserWindow` have the following instance methods:
**Note:** Some methods are only available on specific operating systems and are
labeled as such.
#### `win.destroy()`
Force closing the window, the `unload` and `beforeunload` event won't be emitted
for the web page, and `close` event will also not be emitted
for this window, but it guarantees the `closed` event will be emitted.
#### `win.close()`
Try to close the window. This has the same effect as a user manually clicking
the close button of the window. The web page may cancel the close though. See
the [close event](#event-close).
#### `win.focus()`
Focuses on the window.
#### `win.blur()`
Removes focus from the window.
#### `win.isFocused()`
Returns `boolean` - Whether the window is focused.
#### `win.isDestroyed()`
Returns `boolean` - Whether the window is destroyed.
#### `win.show()`
Shows and gives focus to the window.
#### `win.showInactive()`
Shows the window but doesn't focus on it.
#### `win.hide()`
Hides the window.
#### `win.isVisible()`
Returns `boolean` - Whether the window is visible to the user.
#### `win.isModal()`
Returns `boolean` - Whether current window is a modal window.
#### `win.maximize()`
Maximizes the window. This will also show (but not focus) the window if it
isn't being displayed already.
#### `win.unmaximize()`
Unmaximizes the window.
#### `win.isMaximized()`
Returns `boolean` - Whether the window is maximized.
#### `win.minimize()`
Minimizes the window. On some platforms the minimized window will be shown in
the Dock.
#### `win.restore()`
Restores the window from minimized state to its previous state.
#### `win.isMinimized()`
Returns `boolean` - Whether the window is minimized.
#### `win.setFullScreen(flag)`
* `flag` boolean
Sets whether the window should be in fullscreen mode.
#### `win.isFullScreen()`
Returns `boolean` - Whether the window is in fullscreen mode.
#### `win.setSimpleFullScreen(flag)` _macOS_
* `flag` boolean
Enters or leaves simple fullscreen mode.
Simple fullscreen mode emulates the native fullscreen behavior found in versions of macOS prior to Lion (10.7).
#### `win.isSimpleFullScreen()` _macOS_
Returns `boolean` - Whether the window is in simple (pre-Lion) fullscreen mode.
#### `win.isNormal()`
Returns `boolean` - Whether the window is in normal state (not maximized, not minimized, not in fullscreen mode).
#### `win.setAspectRatio(aspectRatio[, extraSize])`
* `aspectRatio` Float - The aspect ratio to maintain for some portion of the
content view.
* `extraSize` [Size](structures/size.md) (optional) _macOS_ - The extra size not to be included while
maintaining the aspect ratio.
This will make a window maintain an aspect ratio. The extra size allows a
developer to have space, specified in pixels, not included within the aspect
ratio calculations. This API already takes into account the difference between a
window's size and its content size.
Consider a normal window with an HD video player and associated controls.
Perhaps there are 15 pixels of controls on the left edge, 25 pixels of controls
on the right edge and 50 pixels of controls below the player. In order to
maintain a 16:9 aspect ratio (standard aspect ratio for HD @1920x1080) within
the player itself we would call this function with arguments of 16/9 and
{ width: 40, height: 50 }. The second argument doesn't care where the extra width and height
are within the content view--only that they exist. Sum any extra width and
height areas you have within the overall content view.
The aspect ratio is not respected when window is resized programmatically with
APIs like `win.setSize`.
#### `win.setBackgroundColor(backgroundColor)`
* `backgroundColor` string - Color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. The alpha channel is optional for the hex type.
Examples of valid `backgroundColor` values:
* Hex
* #fff (shorthand RGB)
* #ffff (shorthand ARGB)
* #ffffff (RGB)
* #ffffffff (ARGB)
* RGB
* rgb\(([\d]+),\s*([\d]+),\s*([\d]+)\)
* e.g. rgb(255, 255, 255)
* RGBA
* rgba\(([\d]+),\s*([\d]+),\s*([\d]+),\s*([\d.]+)\)
* e.g. rgba(255, 255, 255, 1.0)
* HSL
* hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)
* e.g. hsl(200, 20%, 50%)
* HSLA
* hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)
* e.g. hsla(200, 20%, 50%, 0.5)
* Color name
* Options are listed in [SkParseColor.cpp](https://source.chromium.org/chromium/chromium/src/+/main:third_party/skia/src/utils/SkParseColor.cpp;l=11-152;drc=eea4bf52cb0d55e2a39c828b017c80a5ee054148)
* Similar to CSS Color Module Level 3 keywords, but case-sensitive.
* e.g. `blueviolet` or `red`
Sets the background color of the window. See [Setting `backgroundColor`](#setting-the-backgroundcolor-property).
#### `win.previewFile(path[, displayName])` _macOS_
* `path` string - The absolute path to the file to preview with QuickLook. This
is important as Quick Look uses the file name and file extension on the path
to determine the content type of the file to open.
* `displayName` string (optional) - The name of the file to display on the
Quick Look modal view. This is purely visual and does not affect the content
type of the file. Defaults to `path`.
Uses [Quick Look][quick-look] to preview a file at a given path.
#### `win.closeFilePreview()` _macOS_
Closes the currently open [Quick Look][quick-look] panel.
#### `win.setBounds(bounds[, animate])`
* `bounds` Partial<[Rectangle](structures/rectangle.md)>
* `animate` boolean (optional) _macOS_
Resizes and moves the window to the supplied bounds. Any properties that are not supplied will default to their current values.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
// set all bounds properties
win.setBounds({ x: 440, y: 225, width: 800, height: 600 })
// set a single bounds property
win.setBounds({ width: 100 })
// { x: 440, y: 225, width: 100, height: 600 }
console.log(win.getBounds())
```
#### `win.getBounds()`
Returns [`Rectangle`](structures/rectangle.md) - The `bounds` of the window as `Object`.
#### `win.getBackgroundColor()`
Returns `string` - Gets the background color of the window in Hex (`#RRGGBB`) format.
See [Setting `backgroundColor`](#setting-the-backgroundcolor-property).
**Note:** The alpha value is _not_ returned alongside the red, green, and blue values.
#### `win.setContentBounds(bounds[, animate])`
* `bounds` [Rectangle](structures/rectangle.md)
* `animate` boolean (optional) _macOS_
Resizes and moves the window's client area (e.g. the web page) to
the supplied bounds.
#### `win.getContentBounds()`
Returns [`Rectangle`](structures/rectangle.md) - The `bounds` of the window's client area as `Object`.
#### `win.getNormalBounds()`
Returns [`Rectangle`](structures/rectangle.md) - Contains the window bounds of the normal state
**Note:** whatever the current state of the window : maximized, minimized or in fullscreen, this function always returns the position and size of the window in normal state. In normal state, getBounds and getNormalBounds returns the same [`Rectangle`](structures/rectangle.md).
#### `win.setEnabled(enable)`
* `enable` boolean
Disable or enable the window.

`floating`, `torn-off-menu`, `modal-panel`, `main-menu`, `status`,
`pop-up-menu`, `screen-saver`, and ~~`dock`~~ (Deprecated). The default is
`floating` when `flag` is true. The `level` is reset to `normal` when the
flag is false. Note that from `floating` to `status` included, the window is
placed below the Dock on macOS and below the taskbar on Windows. From
`pop-up-menu` to a higher it is shown above the Dock on macOS and above the
taskbar on Windows. See the [macOS docs][window-levels] for more details.

window.
#### `win.setSheetOffset(offsetY[, offsetX])` _macOS_
* `offsetY` Float
* `offsetX` Float (optional)
Changes the attachment point for sheets on macOS. By default, sheets are
attached just below the window frame, but you may want to display them beneath
a HTML-rendered toolbar. For example:
```javascript
const { BrowserWindow } = require('electron')

const toolbarRect = document.getElementById('toolbar').getBoundingClientRect()
win.setSheetOffset(toolbarRect.height)
```
#### `win.flashFrame(flag)`

Since Windows 10 users can [use their PC as tablet](https://support.microsoft.com/en-us/help/17210/windows-10-use-your-pc-like-a-tablet),
under this mode apps can choose to optimize their UI for tablets, such as
enlarging the titlebar and hiding titlebar buttons.
This API returns whether the window is in tablet mode, and the `resize` event
can be be used to listen to changes to tablet mode.
#### `win.getMediaSourceId()`
Returns `string` - Window id in the format of DesktopCapturerSource's id. For example "window:1324:0".
More precisely the format is `window:id:other_id` where `id` is `HWND` on
Windows, `CGWindowID` (`uint64_t`) on macOS and `Window` (`unsigned long`) on
Linux. `other_id` is used to identify web contents (tabs) so within the same
top level window.
#### `win.getNativeWindowHandle()`
Returns `Buffer` - The platform-specific handle of the window.
The native type of the handle is `HWND` on Windows, `NSView*` on macOS, and
`Window` (`unsigned long`) on Linux.
#### `win.hookWindowMessage(message, callback)` _Windows_
* `message` Integer
* `callback` Function
* `wParam` any - The `wParam` provided to the WndProc
* `lParam` any - The `lParam` provided to the WndProc

Unhooks all of the window messages.
#### `win.setRepresentedFilename(filename)` _macOS_
* `filename` string
Sets the pathname of the file the window represents, and the icon of the file
will show in window's title bar.
#### `win.getRepresentedFilename()` _macOS_
Returns `string` - The pathname of the file the window represents.
#### `win.setDocumentEdited(edited)` _macOS_
* `edited` boolean
Specifies whether the window’s document has been edited, and the icon in title
bar will become gray when set to `true`.
#### `win.isDocumentEdited()` _macOS_
Returns `boolean` - Whether the window's document has been edited.
#### `win.focusOnWebView()`
#### `win.blurWebView()`
#### `win.capturePage([rect])`
* `rect` [Rectangle](structures/rectangle.md) (optional) - The bounds to capture
Returns `Promise<NativeImage>` - Resolves with a [NativeImage](native-image.md)
Captures a snapshot of the page within `rect`. Omitting `rect` will capture the whole visible page. If the page is not visible, `rect` may be empty.
#### `win.loadURL(url[, options])`
* `url` string
* `options` Object (optional)
* `httpReferrer` (string | [Referrer](structures/referrer.md)) (optional) - An HTTP Referrer URL.
* `userAgent` string (optional) - A user agent originating the request.
* `extraHeaders` string (optional) - Extra headers separated by "\n"
* `postData` ([UploadRawData](structures/upload-raw-data.md) | [UploadFile](structures/upload-file.md))[] (optional)
* `baseURLForDataURL` string (optional) - Base URL (with trailing path separator) for files to be loaded by the data URL. This is needed only if the specified `url` is a data URL and needs to load other files.
Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Same as [`webContents.loadURL(url[, options])`](web-contents.md#contentsloadurlurl-options).
The `url` can be a remote address (e.g. `http://`) or a path to a local
HTML file using the `file://` protocol.
To ensure that file URLs are properly formatted, it is recommended to use
Node's [`url.format`](https://nodejs.org/api/url.html#url_url_format_urlobject)
method:
```javascript
const url = require('url').format({
protocol: 'file',
slashes: true,
pathname: require('path').join(__dirname, 'index.html')
})
win.loadURL(url)
```
You can load a URL using a `POST` request with URL-encoded data by doing
the following:
```javascript
win.loadURL('http://localhost:8000/post', {
postData: [{
type: 'rawData',
bytes: Buffer.from('hello=world')
}],
extraHeaders: 'Content-Type: application/x-www-form-urlencoded'
})
```

Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Same as `webContents.loadFile`, `filePath` should be a path to an HTML
file relative to the root of your application. See the `webContents` docs
for more information.
#### `win.reload()`
Same as `webContents.reload`.
#### `win.setMenu(menu)` _Linux_ _Windows_
* `menu` Menu | null
Sets the `menu` as the window's menu bar.
#### `win.removeMenu()` _Linux_ _Windows_
Remove the window's menu bar.
#### `win.setProgressBar(progress[, options])`
* `progress` Double
* `options` Object (optional)
* `mode` string _Windows_ - Mode for the progress bar. Can be `none`, `normal`, `indeterminate`, `error` or `paused`.
Sets progress value in progress bar. Valid range is [0, 1.0].
Remove progress bar when progress < 0;
Change to indeterminate mode when progress > 1.
On Linux platform, only supports Unity desktop environment, you need to specify
the `*.desktop` file name to `desktopName` field in `package.json`. By default,
it will assume `{app.name}.desktop`.
On Windows, a mode can be passed. Accepted values are `none`, `normal`,
`indeterminate`, `error`, and `paused`. If you call `setProgressBar` without a
mode set (but with a value within the valid range), `normal` will be assumed.
#### `win.setOverlayIcon(overlay, description)` _Windows_
* `overlay` [NativeImage](native-image.md) | null - the icon to display on the bottom
right corner of the taskbar icon. If this parameter is `null`, the overlay is
cleared
* `description` string - a description that will be provided to Accessibility
screen readers
Sets a 16 x 16 pixel overlay onto the current taskbar icon, usually used to
convey some sort of application status or to passively notify the user.
#### `win.setHasShadow(hasShadow)`
* `hasShadow` boolean
Sets whether the window should have a shadow.
#### `win.hasShadow()`
Returns `boolean` - Whether the window has a shadow.
#### `win.setOpacity(opacity)` _Windows_ _macOS_
* `opacity` number - between 0.0 (fully transparent) and 1.0 (fully opaque)
Sets the opacity of the window. On Linux, does nothing. Out of bound number
values are clamped to the [0, 1] range.
#### `win.getOpacity()`
Returns `number` - between 0.0 (fully transparent) and 1.0 (fully opaque). On
Linux, always returns 1.
#### `win.setShape(rects)` _Windows_ _Linux_ _Experimental_
* `rects` [Rectangle[]](structures/rectangle.md) - Sets a shape on the window.
Passing an empty list reverts the window to being rectangular.
Setting a window shape determines the area within the window where the system
permits drawing and user interaction. Outside of the given region, no pixels
will be drawn and no mouse events will be registered. Mouse events outside of
the region will not be received by that window, but will fall through to
whatever is behind the window.
#### `win.setThumbarButtons(buttons)` _Windows_
* `buttons` [ThumbarButton[]](structures/thumbar-button.md)
Returns `boolean` - Whether the buttons were added successfully
Add a thumbnail toolbar with a specified set of buttons to the thumbnail image
of a window in a taskbar button layout. Returns a `boolean` object indicates
whether the thumbnail has been added successfully.
The number of buttons in thumbnail toolbar should be no greater than 7 due to
the limited room. Once you setup the thumbnail toolbar, the toolbar cannot be
removed due to the platform's limitation. But you can call the API with an empty
array to clean the buttons.
The `buttons` is an array of `Button` objects:
* `Button` Object
* `icon` [NativeImage](native-image.md) - The icon showing in thumbnail
toolbar.
* `click` Function
* `tooltip` string (optional) - The text of the button's tooltip.
* `flags` string[] (optional) - Control specific states and behaviors of the
button. By default, it is `['enabled']`.
The `flags` is an array that can include following `string`s:
* `enabled` - The button is active and available to the user.
* `disabled` - The button is disabled. It is present, but has a visual state
indicating it will not respond to user action.
* `dismissonclick` - When the button is clicked, the thumbnail window closes
immediately.
* `nobackground` - Do not draw a button border, use only the image.
* `hidden` - The button is not shown to the user.
* `noninteractive` - The button is enabled but not interactive; no pressed
button state is drawn. This value is intended for instances where the button
is used in a notification.
#### `win.setThumbnailClip(region)` _Windows_
* `region` [Rectangle](structures/rectangle.md) - Region of the window
Sets the region of the window to show as the thumbnail image displayed when
hovering over the window in the taskbar. You can reset the thumbnail to be
the entire window by specifying an empty region:
`{ x: 0, y: 0, width: 0, height: 0 }`.
#### `win.setThumbnailToolTip(toolTip)` _Windows_
* `toolTip` string
Sets the toolTip that is displayed when hovering over the window thumbnail
in the taskbar.
#### `win.setAppDetails(options)` _Windows_

* `appId` string (optional) - Window's [App User Model ID](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391569(v=vs.85).aspx).
It has to be set, otherwise the other options will have no effect.
* `appIconPath` string (optional) - Window's [Relaunch Icon](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391573(v=vs.85).aspx).
* `appIconIndex` Integer (optional) - Index of the icon in `appIconPath`.
Ignored when `appIconPath` is not set. Default is `0`.
* `relaunchCommand` string (optional) - Window's [Relaunch Command](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391571(v=vs.85).aspx).
* `relaunchDisplayName` string (optional) - Window's [Relaunch Display Name](https://msdn.microsoft.com/en-us/library/windows/desktop/dd391572(v=vs.85).aspx).
Sets the properties for the window's taskbar button.
**Note:** `relaunchCommand` and `relaunchDisplayName` must always be set
together. If one of those properties is not set, then neither will be used.
#### `win.showDefinitionForSelection()` _macOS_
Same as `webContents.showDefinitionForSelection()`.
#### `win.setIcon(icon)` _Windows_ _Linux_
* `icon` [NativeImage](native-image.md) | string
Changes window icon.
#### `win.setWindowButtonVisibility(visible)` _macOS_
* `visible` boolean
Sets whether the window traffic light buttons should be visible.
#### `win.setAutoHideMenuBar(hide)` _Windows_ _Linux_
* `hide` boolean

Returns `boolean` - Whether menu bar automatically hides itself.
#### `win.setMenuBarVisibility(visible)` _Windows_ _Linux_
* `visible` boolean
Sets whether the menu bar should be visible. If the menu bar is auto-hide, users can still bring up the menu bar by pressing the single `Alt` key.

#### `win.setVisibleOnAllWorkspaces(visible[, options])` _macOS_ _Linux_
* `visible` boolean
* `options` Object (optional)
* `visibleOnFullScreen` boolean (optional) _macOS_ - Sets whether
the window should be visible above fullscreen windows.
* `skipTransformProcessType` boolean (optional) _macOS_ - Calling
setVisibleOnAllWorkspaces will by default transform the process
type between UIElementApplication and ForegroundApplication to
ensure the correct behavior. However, this will hide the window
and dock for a short time every time it is called. If your window
is already of type UIElementApplication, you can bypass this
transformation by passing true to skipTransformProcessType.
Sets whether the window should be visible on all workspaces.
**Note:** This API does nothing on Windows.
#### `win.isVisibleOnAllWorkspaces()` _macOS_ _Linux_
Returns `boolean` - Whether the window is visible on all workspaces.
**Note:** This API always returns false on Windows.
#### `win.setIgnoreMouseEvents(ignore[, options])`
* `ignore` boolean
* `options` Object (optional)
* `forward` boolean (optional) _macOS_ _Windows_ - If true, forwards mouse move
messages to Chromium, enabling mouse related events such as `mouseleave`.
Only used when `ignore` is true. If `ignore` is false, forwarding is always
disabled regardless of this value.
Makes the window ignore all mouse events.
All mouse events happened in this window will be passed to the window below
this window, but if this window has focus, it will still receive keyboard
events.
#### `win.setContentProtection(enable)` _macOS_ _Windows_
* `enable` boolean
Prevents the window contents from being captured by other apps.
On macOS it sets the NSWindow's sharingType to NSWindowSharingNone.

[Documentation] browserWindow event.returnValue contradiction
|
### Documentation Issue
Please see this commit https://github.com/electron/electron/commit/bb153ee79e6bb4e54d4d075f64a448f498fbeff8 which, without explanation, says that it is both _recommended_ **and** _not recommended_ to set the event.returnValue directly.
Is it possible to disambiguate this or provide a further explanation for the comment?

# BrowserWindow
> Create and control browser windows.
Process: [Main](../glossary.md#main-process)
```javascript
// In the main process.
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
// Load a remote URL
win.loadURL('https://github.com')
// Or load a local HTML file
win.loadFile('index.html')
```
## Window customization
The `BrowserWindow` class exposes various ways to modify the look and behavior of
your app's windows. For more details, see the [Window Customization](../tutorial/window-customization.md)
tutorial.
## Showing the window gracefully
When loading a page in the window directly, users may see the page load incrementally,
which is not a good experience for a native app. To make the window display
without a visual flash, there are two solutions for different situations.
### Using the `ready-to-show` event
While loading the page, the `ready-to-show` event will be emitted when the renderer
process has rendered the page for the first time if the window has not been shown yet. Showing
the window after this event will have no visual flash:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ show: false })
win.once('ready-to-show', () => {
win.show()
})
```
This event is usually emitted after the `did-finish-load` event, but for
pages with many remote resources, it may be emitted before the `did-finish-load`
event.
Please note that using this event implies that the renderer will be considered "visible" and
paint even though `show` is false. This event will never fire if you use `paintWhenInitiallyHidden: false`
### Setting the `backgroundColor` property
For a complex app, the `ready-to-show` event could be emitted too late, making
the app feel slow. In this case, it is recommended to show the window
immediately, and use a `backgroundColor` close to your app's background:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ backgroundColor: '#2e2c29' })
win.loadURL('https://github.com')
```
Note that even for apps that use `ready-to-show` event, it is still recommended
to set `backgroundColor` to make the app feel more native.
Some examples of valid `backgroundColor` values include:
```js
const win = new BrowserWindow()
win.setBackgroundColor('hsl(230, 100%, 50%)')
win.setBackgroundColor('rgb(255, 145, 145)')
win.setBackgroundColor('#ff00a3')
win.setBackgroundColor('blueviolet')
```
For more information about these color types see valid options in [win.setBackgroundColor](browser-window.md#winsetbackgroundcolorbackgroundcolor).
## Parent and child windows
By using `parent` option, you can create child windows:
```javascript
const { BrowserWindow } = require('electron')
const top = new BrowserWindow()
const child = new BrowserWindow({ parent: top })
child.show()
top.show()
```
The `child` window will always show on top of the `top` window.
## Modal windows
A modal window is a child window that disables parent window, to create a modal
window, you have to set both `parent` and `modal` options:
```javascript
const { BrowserWindow } = require('electron')
const child = new BrowserWindow({ parent: top, modal: true, show: false })
child.loadURL('https://github.com')
child.once('ready-to-show', () => {
child.show()
})
```
## Page visibility
The [Page Visibility API][page-visibility-api] works as follows:
* On all platforms, the visibility state tracks whether the window is
hidden/minimized or not.
* Additionally, on macOS, the visibility state also tracks the window
occlusion state. If the window is occluded (i.e. fully covered) by another
window, the visibility state will be `hidden`. On other platforms, the
visibility state will be `hidden` only when the window is minimized or
explicitly hidden with `win.hide()`.
* If a `BrowserWindow` is created with `show: false`, the initial visibility
state will be `visible` despite the window actually being hidden.
* If `backgroundThrottling` is disabled, the visibility state will remain
`visible` even if the window is minimized, occluded, or hidden.
It is recommended that you pause expensive operations when the visibility
state is `hidden` in order to minimize power consumption.
## Platform notices
* On macOS modal windows will be displayed as sheets attached to the parent window.
* On macOS the child windows will keep the relative position to parent window
when parent window moves, while on Windows and Linux child windows will not
move.
* On Linux the type of modal windows will be changed to `dialog`.
* On Linux many desktop environments do not support hiding a modal window.
## Class: BrowserWindow
> Create and control browser windows.
Process: [Main](../glossary.md#main-process)
`BrowserWindow` is an [EventEmitter][event-emitter].
It creates a new `BrowserWindow` with native properties as set by the `options`.
### `new BrowserWindow([options])`
* `options` Object (optional)
* `width` Integer (optional) - Window's width in pixels. Default is `800`.
* `height` Integer (optional) - Window's height in pixels. Default is `600`.
* `x` Integer (optional) - (**required** if y is used) Window's left offset from screen.
Default is to center the window.
* `y` Integer (optional) - (**required** if x is used) Window's top offset from screen.
Default is to center the window.
* `useContentSize` boolean (optional) - The `width` and `height` would be used as web
page's size, which means the actual window's size will include window
frame's size and be slightly larger. Default is `false`.
* `center` boolean (optional) - Show window in the center of the screen. Default is `false`.
* `minWidth` Integer (optional) - Window's minimum width. Default is `0`.
* `minHeight` Integer (optional) - Window's minimum height. Default is `0`.
* `maxWidth` Integer (optional) - Window's maximum width. Default is no limit.
* `maxHeight` Integer (optional) - Window's maximum height. Default is no limit.
* `resizable` boolean (optional) - Whether window is resizable. Default is `true`.
* `movable` boolean (optional) _macOS_ _Windows_ - Whether window is
movable. This is not implemented on Linux. Default is `true`.
* `minimizable` boolean (optional) _macOS_ _Windows_ - Whether window is
minimizable. This is not implemented on Linux. Default is `true`.
* `maximizable` boolean (optional) _macOS_ _Windows_ - Whether window is
maximizable. This is not implemented on Linux. Default is `true`.
* `closable` boolean (optional) _macOS_ _Windows_ - Whether window is
closable. This is not implemented on Linux. Default is `true`.
* `focusable` boolean (optional) - Whether the window can be focused. Default is
`true`. On Windows setting `focusable: false` also implies setting
`skipTaskbar: true`. On Linux setting `focusable: false` makes the window
stop interacting with wm, so the window will always stay on top in all
workspaces.
* `alwaysOnTop` boolean (optional) - Whether the window should always stay on top of
other windows. Default is `false`.
* `fullscreen` boolean (optional) - Whether the window should show in fullscreen. When
explicitly set to `false` the fullscreen button will be hidden or disabled
on macOS. Default is `false`.
* `fullscreenable` boolean (optional) - Whether the window can be put into fullscreen
mode. On macOS, also whether the maximize/zoom button should toggle full
screen mode or maximize window. Default is `true`.
* `simpleFullscreen` boolean (optional) _macOS_ - Use pre-Lion fullscreen on
macOS. Default is `false`.
* `skipTaskbar` boolean (optional) _macOS_ _Windows_ - Whether to show the window in taskbar.
Default is `false`.
* `kiosk` boolean (optional) - Whether the window is in kiosk mode. Default is `false`.
* `title` string (optional) - Default window title. Default is `"Electron"`. If the HTML tag `<title>` is defined in the HTML file loaded by `loadURL()`, this property will be ignored.
* `icon` ([NativeImage](native-image.md) | string) (optional) - The window icon. On Windows it is
recommended to use `ICO` icons to get best visual effects, you can also
leave it undefined so the executable's icon will be used.
* `show` boolean (optional) - Whether window should be shown when created. Default is
`true`.
* `paintWhenInitiallyHidden` boolean (optional) - Whether the renderer should be active when `show` is `false` and it has just been created. In order for `document.visibilityState` to work correctly on first load with `show: false` you should set this to `false`. Setting this to `false` will cause the `ready-to-show` event to not fire. Default is `true`.
* `frame` boolean (optional) - Specify `false` to create a
[frameless window](../tutorial/window-customization.md#create-frameless-windows). Default is `true`.
* `parent` BrowserWindow (optional) - Specify parent window. Default is `null`.
* `modal` boolean (optional) - Whether this is a modal window. This only works when the
window is a child window. Default is `false`.
* `acceptFirstMouse` boolean (optional) _macOS_ - Whether clicking an
inactive window will also click through to the web contents. Default is
`false` on macOS. This option is not configurable on other platforms.
* `disableAutoHideCursor` boolean (optional) - Whether to hide cursor when typing.
Default is `false`.
* `autoHideMenuBar` boolean (optional) - Auto hide the menu bar unless the `Alt`
key is pressed. Default is `false`.
* `enableLargerThanScreen` boolean (optional) _macOS_ - Enable the window to
be resized larger than screen. Only relevant for macOS, as other OSes
allow larger-than-screen windows by default. Default is `false`.
* `backgroundColor` string (optional) - The window's background color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. Alpha in #AARRGGBB format is supported if `transparent` is set to `true`. Default is `#FFF` (white). See [win.setBackgroundColor](browser-window.md#winsetbackgroundcolorbackgroundcolor) for more information.
* `hasShadow` boolean (optional) - Whether window should have a shadow. Default is `true`.
* `opacity` number (optional) _macOS_ _Windows_ - Set the initial opacity of
the window, between 0.0 (fully transparent) and 1.0 (fully opaque). This
is only implemented on Windows and macOS.
* `darkTheme` boolean (optional) - Forces using dark theme for the window, only works on
some GTK+3 desktop environments. Default is `false`.
* `transparent` boolean (optional) - Makes the window [transparent](../tutorial/window-customization.md#create-transparent-windows).
Default is `false`. On Windows, does not work unless the window is frameless.
* `type` string (optional) - The type of window, default is normal window. See more about
this below.
* `visualEffectState` string (optional) _macOS_ - Specify how the material
appearance should reflect window activity state on macOS. Must be used
with the `vibrancy` property. Possible values are:
* `followWindow` - The backdrop should automatically appear active when the window is active, and inactive when it is not. This is the default.
* `active` - The backdrop should always appear active.
* `inactive` - The backdrop should always appear inactive.
* `titleBarStyle` string (optional) _macOS_ _Windows_ - The style of window title bar.
Default is `default`. Possible values are:
* `default` - Results in the standard title bar for macOS or Windows respectively.
* `hidden` - Results in a hidden title bar and a full size content window. On macOS, the window still has the standard window controls (“traffic lights”) in the top left. On Windows, when combined with `titleBarOverlay: true` it will activate the Window Controls Overlay (see `titleBarOverlay` for more information), otherwise no window controls will be shown.
* `hiddenInset` _macOS_ - Only on macOS, results in a hidden title bar
with an alternative look where the traffic light buttons are slightly
more inset from the window edge.
* `customButtonsOnHover` _macOS_ - Only on macOS, results in a hidden
title bar and a full size content window, the traffic light buttons will
display when being hovered over in the top left of the window.
**Note:** This option is currently experimental.
* `trafficLightPosition` [Point](structures/point.md) (optional) _macOS_ -
Set a custom position for the traffic light buttons in frameless windows.
* `roundedCorners` boolean (optional) _macOS_ - Whether frameless window
should have rounded corners on macOS. Default is `true`.
* `fullscreenWindowTitle` boolean (optional) _macOS_ _Deprecated_ - Shows
the title in the title bar in full screen mode on macOS for `hiddenInset`
titleBarStyle. Default is `false`.
* `thickFrame` boolean (optional) - Use `WS_THICKFRAME` style for frameless windows on
Windows, which adds standard window frame. Setting it to `false` will remove
window shadow and window animations. Default is `true`.
* `vibrancy` string (optional) _macOS_ - Add a type of vibrancy effect to
the window, only on macOS. Can be `appearance-based`, `light`, `dark`,
`titlebar`, `selection`, `menu`, `popover`, `sidebar`, `medium-light`,
`ultra-dark`, `header`, `sheet`, `window`, `hud`, `fullscreen-ui`,
`tooltip`, `content`, `under-window`, or `under-page`. Please note that
`appearance-based`, `light`, `dark`, `medium-light`, and `ultra-dark` are
deprecated and have been removed in macOS Catalina (10.15).
* `zoomToPageWidth` boolean (optional) _macOS_ - Controls the behavior on
macOS when option-clicking the green stoplight button on the toolbar or by
clicking the Window > Zoom menu item. If `true`, the window will grow to
the preferred width of the web page when zoomed, `false` will cause it to
zoom to the width of the screen. This will also affect the behavior when
calling `maximize()` directly. Default is `false`.
* `tabbingIdentifier` string (optional) _macOS_ - Tab group name, allows
opening the window as a native tab on macOS 10.12+. Windows with the same
tabbing identifier will be grouped together. This also adds a native new
tab button to your window's tab bar and allows your `app` and window to
receive the `new-window-for-tab` event.
* `webPreferences` Object (optional) - Settings of web page's features.
* `devTools` boolean (optional) - Whether to enable DevTools. If it is set to `false`, can not use `BrowserWindow.webContents.openDevTools()` to open DevTools. Default is `true`.
* `nodeIntegration` boolean (optional) - Whether node integration is enabled.
Default is `false`.
* `nodeIntegrationInWorker` boolean (optional) - Whether node integration is
enabled in web workers. Default is `false`. More about this can be found
in [Multithreading](../tutorial/multithreading.md).
* `nodeIntegrationInSubFrames` boolean (optional) - Experimental option for
enabling Node.js support in sub-frames such as iframes and child windows. All your preloads will load for
every iframe, you can use `process.isMainFrame` to determine if you are
in the main frame or not.
* `preload` string (optional) - Specifies a script that will be loaded before other
scripts run in the page. This script will always have access to node APIs
no matter whether node integration is turned on or off. The value should
be the absolute file path to the script.
When node integration is turned off, the preload script can reintroduce
Node global symbols back to the global scope. See example
[here](context-bridge.md#exposing-node-global-symbols).
* `sandbox` boolean (optional) - If set, this will sandbox the renderer
associated with the window, making it compatible with the Chromium
OS-level sandbox and disabling the Node.js engine. This is not the same as
the `nodeIntegration` option and the APIs available to the preload script
are more limited. Read more about the option [here](../tutorial/sandbox.md).
* `session` [Session](session.md#class-session) (optional) - Sets the session used by the
page. Instead of passing the Session object directly, you can also choose to
use the `partition` option instead, which accepts a partition string. When
both `session` and `partition` are provided, `session` will be preferred.
Default is the default session.
* `partition` string (optional) - Sets the session used by the page according to the
session's partition string. If `partition` starts with `persist:`, the page
will use a persistent session available to all pages in the app with the
same `partition`. If there is no `persist:` prefix, the page will use an
in-memory session. By assigning the same `partition`, multiple pages can share
the same session. Default is the default session.
* `zoomFactor` number (optional) - The default zoom factor of the page, `3.0` represents
`300%`. Default is `1.0`.
* `javascript` boolean (optional) - Enables JavaScript support. Default is `true`.
* `webSecurity` boolean (optional) - When `false`, it will disable the
same-origin policy (usually using testing websites by people), and set
`allowRunningInsecureContent` to `true` if this options has not been set
by user. Default is `true`.
* `allowRunningInsecureContent` boolean (optional) - Allow an https page to run
JavaScript, CSS or plugins from http URLs. Default is `false`.
* `images` boolean (optional) - Enables image support. Default is `true`.
* `imageAnimationPolicy` string (optional) - Specifies how to run image animations (E.g. GIFs). Can be `animate`, `animateOnce` or `noAnimation`. Default is `animate`.
* `textAreasAreResizable` boolean (optional) - Make TextArea elements resizable. Default
is `true`.
* `webgl` boolean (optional) - Enables WebGL support. Default is `true`.
* `plugins` boolean (optional) - Whether plugins should be enabled. Default is `false`.
* `experimentalFeatures` boolean (optional) - Enables Chromium's experimental features.
Default is `false`.
* `scrollBounce` boolean (optional) _macOS_ - Enables scroll bounce
(rubber banding) effect on macOS. Default is `false`.
* `enableBlinkFeatures` string (optional) - A list of feature strings separated by `,`, like
`CSSVariables,KeyboardEventKey` to enable. The full list of supported feature
strings can be found in the [RuntimeEnabledFeatures.json5][runtime-enabled-features]
file.
* `disableBlinkFeatures` string (optional) - A list of feature strings separated by `,`,
like `CSSVariables,KeyboardEventKey` to disable. The full list of supported
feature strings can be found in the
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
* `defaultFontFamily` Object (optional) - Sets the default font for the font-family.
* `standard` string (optional) - Defaults to `Times New Roman`.
* `serif` string (optional) - Defaults to `Times New Roman`.
* `sansSerif` string (optional) - Defaults to `Arial`.
* `monospace` string (optional) - Defaults to `Courier New`.
* `cursive` string (optional) - Defaults to `Script`.
* `fantasy` string (optional) - Defaults to `Impact`.
* `defaultFontSize` Integer (optional) - Defaults to `16`.
* `defaultMonospaceFontSize` Integer (optional) - Defaults to `13`.
* `minimumFontSize` Integer (optional) - Defaults to `0`.
* `defaultEncoding` string (optional) - Defaults to `ISO-8859-1`.
* `backgroundThrottling` boolean (optional) - Whether to throttle animations and timers
when the page becomes background. This also affects the
[Page Visibility API](#page-visibility). Defaults to `true`.
* `offscreen` boolean (optional) - Whether to enable offscreen rendering for the browser
window. Defaults to `false`. See the
[offscreen rendering tutorial](../tutorial/offscreen-rendering.md) for
more details.
* `contextIsolation` boolean (optional) - Whether to run Electron APIs and
the specified `preload` script in a separate JavaScript context. Defaults
to `true`. The context that the `preload` script runs in will only have
access to its own dedicated `document` and `window` globals, as well as
its own set of JavaScript builtins (`Array`, `Object`, `JSON`, etc.),
which are all invisible to the loaded content. The Electron API will only
be available in the `preload` script and not the loaded page. This option
should be used when loading potentially untrusted remote content to ensure
the loaded content cannot tamper with the `preload` script and any
Electron APIs being used. This option uses the same technique used by
[Chrome Content Scripts][chrome-content-scripts]. You can access this
context in the dev tools by selecting the 'Electron Isolated Context'
entry in the combo box at the top of the Console tab.
* `webviewTag` boolean (optional) - Whether to enable the [`<webview>` tag](webview-tag.md).
Defaults to `false`. **Note:** The
`preload` script configured for the `<webview>` will have node integration
enabled when it is executed so you should ensure remote/untrusted content
is not able to create a `<webview>` tag with a possibly malicious `preload`
script. You can use the `will-attach-webview` event on [webContents](web-contents.md)
to strip away the `preload` script and to validate or alter the
`<webview>`'s initial settings.
* `additionalArguments` string[] (optional) - A list of strings that will be appended
to `process.argv` in the renderer process of this app. Useful for passing small
bits of data down to renderer process preload scripts.
* `safeDialogs` boolean (optional) - Whether to enable browser style
consecutive dialog protection. Default is `false`.
* `safeDialogsMessage` string (optional) - The message to display when
consecutive dialog protection is triggered. If not defined the default
message would be used, note that currently the default message is in
English and not localized.
* `disableDialogs` boolean (optional) - Whether to disable dialogs
completely. Overrides `safeDialogs`. Default is `false`.
* `navigateOnDragDrop` boolean (optional) - Whether dragging and dropping a
file or link onto the page causes a navigation. Default is `false`.
* `autoplayPolicy` string (optional) - Autoplay policy to apply to
content in the window, can be `no-user-gesture-required`,
`user-gesture-required`, `document-user-activation-required`. Defaults to
`no-user-gesture-required`.
* `disableHtmlFullscreenWindowResize` boolean (optional) - Whether to
prevent the window from resizing when entering HTML Fullscreen. Default
is `false`.
* `accessibleTitle` string (optional) - An alternative title string provided only
to accessibility tools such as screen readers. This string is not directly
visible to users.
* `spellcheck` boolean (optional) - Whether to enable the builtin spellchecker.
Default is `true`.
* `enableWebSQL` boolean (optional) - Whether to enable the [WebSQL api](https://www.w3.org/TR/webdatabase/).
Default is `true`.
* `v8CacheOptions` string (optional) - Enforces the v8 code caching policy
used by blink. Accepted values are
* `none` - Disables code caching
* `code` - Heuristic based code caching
* `bypassHeatCheck` - Bypass code caching heuristics but with lazy compilation
* `bypassHeatCheckAndEagerCompile` - Same as above except compilation is eager.
Default policy is `code`.
* `enablePreferredSizeMode` boolean (optional) - Whether to enable
preferred size mode. The preferred size is the minimum size needed to
contain the layout of the document—without requiring scrolling. Enabling
this will cause the `preferred-size-changed` event to be emitted on the
`WebContents` when the preferred size changes. Default is `false`.
* `titleBarOverlay` Object | Boolean (optional) - When using a frameless window in conjunction with `win.setWindowButtonVisibility(true)` on macOS or using a `titleBarStyle` so that the standard window controls ("traffic lights" on macOS) are visible, this property enables the Window Controls Overlay [JavaScript APIs][overlay-javascript-apis] and [CSS Environment Variables][overlay-css-env-vars]. Specifying `true` will result in an overlay with default system colors. Default is `false`.
* `color` String (optional) _Windows_ - The CSS color of the Window Controls Overlay when enabled. Default is the system color.
* `symbolColor` String (optional) _Windows_ - The CSS color of the symbols on the Window Controls Overlay when enabled. Default is the system color.
* `height` Integer (optional) _macOS_ _Windows_ - The height of the title bar and Window Controls Overlay in pixels. Default is system height.
When setting minimum or maximum window size with `minWidth`/`maxWidth`/
`minHeight`/`maxHeight`, it only constrains the users. It won't prevent you from
passing a size that does not follow size constraints to `setBounds`/`setSize` or
to the constructor of `BrowserWindow`.
The possible values and behaviors of the `type` option are platform dependent.
Possible values are:
* On Linux, possible types are `desktop`, `dock`, `toolbar`, `splash`,
`notification`.
* On macOS, possible types are `desktop`, `textured`.
* The `textured` type adds metal gradient appearance
(`NSTexturedBackgroundWindowMask`).
* The `desktop` type places the window at the desktop background window level
(`kCGDesktopWindowLevel - 1`). Note that desktop window will not receive
focus, keyboard or mouse events, but you can use `globalShortcut` to receive
input sparingly.
* On Windows, possible type is `toolbar`.
### Instance Events
Objects created with `new BrowserWindow` emit the following events:
**Note:** Some events are only available on specific operating systems and are
labeled as such.
#### Event: 'page-title-updated'
Returns:
* `event` Event
* `title` string
* `explicitSet` boolean
Emitted when the document changed its title, calling `event.preventDefault()`
will prevent the native window's title from changing.
`explicitSet` is false when title is synthesized from file URL.
#### Event: 'close'
Returns:
* `event` Event
Emitted when the window is going to be closed. It's emitted before the
`beforeunload` and `unload` event of the DOM. Calling `event.preventDefault()`
will cancel the close.
Usually you would want to use the `beforeunload` handler to decide whether the
window should be closed, which will also be called when the window is
reloaded. In Electron, returning any value other than `undefined` would cancel the
close. For example:
```javascript
window.onbeforeunload = (e) => {
console.log('I do not want to be closed')
// Unlike usual browsers that a message box will be prompted to users, returning
// a non-void value will silently cancel the close.
// It is recommended to use the dialog API to let the user confirm closing the
// application.
e.returnValue = false // equivalent to `return false` but not recommended
}
```
_**Note**: There is a subtle difference between the behaviors of `window.onbeforeunload = handler` and `window.addEventListener('beforeunload', handler)`. It is recommended to always set the `event.returnValue` explicitly, instead of only returning a value, as the former works more consistently within Electron._
#### Event: 'closed'
Emitted when the window is closed. After you have received this event you should
remove the reference to the window and avoid using it any more.
#### Event: 'session-end' _Windows_
Emitted when window session is going to end due to force shutdown or machine restart
or session log off.
#### Event: 'unresponsive'
Emitted when the web page becomes unresponsive.
#### Event: 'responsive'
Emitted when the unresponsive web page becomes responsive again.
#### Event: 'blur'
Emitted when the window loses focus.
#### Event: 'focus'
Emitted when the window gains focus.
#### Event: 'show'
Emitted when the window is shown.
#### Event: 'hide'
Emitted when the window is hidden.
#### Event: 'ready-to-show'
Emitted when the web page has been rendered (while not being shown) and window can be displayed without
a visual flash.
Please note that using this event implies that the renderer will be considered "visible" and
paint even though `show` is false. This event will never fire if you use `paintWhenInitiallyHidden: false`
#### Event: 'maximize'
Emitted when window is maximized.
#### Event: 'unmaximize'
Emitted when the window exits from a maximized state.
#### Event: 'minimize'
Emitted when the window is minimized.
#### Event: 'restore'
Emitted when the window is restored from a minimized state.
#### Event: 'will-resize' _macOS_ _Windows_
Returns:
* `event` Event
* `newBounds` [Rectangle](structures/rectangle.md) - Size the window is being resized to.
* `details` Object
* `edge` (string) - The edge of the window being dragged for resizing. Can be `bottom`, `left`, `right`, `top-left`, `top-right`, `bottom-left` or `bottom-right`.
Emitted before the window is resized. Calling `event.preventDefault()` will prevent the window from being resized.
Note that this is only emitted when the window is being resized manually. Resizing the window with `setBounds`/`setSize` will not emit this event.
The possible values and behaviors of the `edge` option are platform dependent. Possible values are:
* On Windows, possible values are `bottom`, `top`, `left`, `right`, `top-left`, `top-right`, `bottom-left`, `bottom-right`.
* On macOS, possible values are `bottom` and `right`.
* The value `bottom` is used to denote vertical resizing.
* The value `right` is used to denote horizontal resizing.
#### Event: 'resize'
Emitted after the window has been resized.
#### Event: 'resized' _macOS_ _Windows_
Emitted once when the window has finished being resized.
This is usually emitted when the window has been resized manually. On macOS, resizing the window with `setBounds`/`setSize` and setting the `animate` parameter to `true` will also emit this event once resizing has finished.
#### Event: 'will-move' _macOS_ _Windows_
Returns:
* `event` Event
* `newBounds` [Rectangle](structures/rectangle.md) - Location the window is being moved to.
Emitted before the window is moved. On Windows, calling `event.preventDefault()` will prevent the window from being moved.
Note that this is only emitted when the window is being moved manually. Moving the window with `setPosition`/`setBounds`/`center` will not emit this event.
#### Event: 'move'
Emitted when the window is being moved to a new position.
#### Event: 'moved' _macOS_ _Windows_
Emitted once when the window is moved to a new position.
__Note__: On macOS this event is an alias of `move`.
#### Event: 'enter-full-screen'
Emitted when the window enters a full-screen state.
#### Event: 'leave-full-screen'
Emitted when the window leaves a full-screen state.
#### Event: 'enter-html-full-screen'
Emitted when the window enters a full-screen state triggered by HTML API.
#### Event: 'leave-html-full-screen'
Emitted when the window leaves a full-screen state triggered by HTML API.
#### Event: 'always-on-top-changed'
Returns:
* `event` Event
* `isAlwaysOnTop` boolean
Emitted when the window is set or unset to show always on top of other windows.
#### Event: 'app-command' _Windows_ _Linux_
Returns:
* `event` Event
* `command` string
Emitted when an [App Command](https://msdn.microsoft.com/en-us/library/windows/desktop/ms646275(v=vs.85).aspx)
is invoked. These are typically related to keyboard media keys or browser
commands, as well as the "Back" button built into some mice on Windows.
Commands are lowercased, underscores are replaced with hyphens, and the
`APPCOMMAND_` prefix is stripped off.
e.g. `APPCOMMAND_BROWSER_BACKWARD` is emitted as `browser-backward`.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.on('app-command', (e, cmd) => {
// Navigate the window back when the user hits their mouse back button
if (cmd === 'browser-backward' && win.webContents.canGoBack()) {
win.webContents.goBack()
}
})
```
The following app commands are explicitly supported on Linux:
* `browser-backward`
* `browser-forward`
#### Event: 'scroll-touch-begin' _macOS_
Emitted when scroll wheel event phase has begun.
#### Event: 'scroll-touch-end' _macOS_
Emitted when scroll wheel event phase has ended.
#### Event: 'scroll-touch-edge' _macOS_
Emitted when scroll wheel event phase filed upon reaching the edge of element.
#### Event: 'swipe' _macOS_
Returns:
* `event` Event
* `direction` string
Emitted on 3-finger swipe. Possible directions are `up`, `right`, `down`, `left`.
The method underlying this event is built to handle older macOS-style trackpad swiping,
where the content on the screen doesn't move with the swipe. Most macOS trackpads are not
configured to allow this kind of swiping anymore, so in order for it to emit properly the
'Swipe between pages' preference in `System Preferences > Trackpad > More Gestures` must be
set to 'Swipe with two or three fingers'.
#### Event: 'rotate-gesture' _macOS_
Returns:
* `event` Event
* `rotation` Float
Emitted on trackpad rotation gesture. Continually emitted until rotation gesture is
ended. The `rotation` value on each emission is the angle in degrees rotated since
the last emission. The last emitted event upon a rotation gesture will always be of
value `0`. Counter-clockwise rotation values are positive, while clockwise ones are
negative.
#### Event: 'sheet-begin' _macOS_
Emitted when the window opens a sheet.
#### Event: 'sheet-end' _macOS_
Emitted when the window has closed a sheet.
#### Event: 'new-window-for-tab' _macOS_
Emitted when the native new tab button is clicked.
#### Event: 'system-context-menu' _Windows_
Returns:
* `event` Event
* `point` [Point](structures/point.md) - The screen coordinates the context menu was triggered at
Emitted when the system context menu is triggered on the window, this is
normally only triggered when the user right clicks on the non-client area
of your window. This is the window titlebar or any area you have declared
as `-webkit-app-region: drag` in a frameless window.
Calling `event.preventDefault()` will prevent the menu from being displayed.

```
#### `win.accessibleTitle`
A `string` property that defines an alternative title provided only to
accessibility tools such as screen readers. This string is not directly
visible to users.

Restores the window from minimized state to its previous state.
#### `win.isMinimized()`
Returns `boolean` - Whether the window is minimized.
#### `win.setFullScreen(flag)`
* `flag` boolean
Sets whether the window should be in fullscreen mode.
#### `win.isFullScreen()`
Returns `boolean` - Whether the window is in fullscreen mode.
#### `win.setSimpleFullScreen(flag)` _macOS_
* `flag` boolean
Enters or leaves simple fullscreen mode.
Simple fullscreen mode emulates the native fullscreen behavior found in versions of macOS prior to Lion (10.7).
#### `win.isSimpleFullScreen()` _macOS_
Returns `boolean` - Whether the window is in simple (pre-Lion) fullscreen mode.
#### `win.isNormal()`
Returns `boolean` - Whether the window is in normal state (not maximized, not minimized, not in fullscreen mode).
#### `win.setAspectRatio(aspectRatio[, extraSize])`
* `aspectRatio` Float - The aspect ratio to maintain for some portion of the
content view.
* `extraSize` [Size](structures/size.md) (optional) _macOS_ - The extra size not to be included while
maintaining the aspect ratio.
This will make a window maintain an aspect ratio. The extra size allows a
developer to have space, specified in pixels, not included within the aspect
ratio calculations. This API already takes into account the difference between a
window's size and its content size.
Consider a normal window with an HD video player and associated controls.
Perhaps there are 15 pixels of controls on the left edge, 25 pixels of controls
on the right edge and 50 pixels of controls below the player. In order to
maintain a 16:9 aspect ratio (standard aspect ratio for HD @1920x1080) within
the player itself we would call this function with arguments of 16/9 and
{ width: 40, height: 50 }. The second argument doesn't care where the extra width and height
are within the content view--only that they exist. Sum any extra width and
height areas you have within the overall content view.
The aspect ratio is not respected when window is resized programmatically with
APIs like `win.setSize`.
#### `win.setBackgroundColor(backgroundColor)`
* `backgroundColor` string - Color in Hex, RGB, RGBA, HSL, HSLA or named CSS color format. The alpha channel is optional for the hex type.
Examples of valid `backgroundColor` values:
* Hex
* #fff (shorthand RGB)
* #ffff (shorthand ARGB)
* #ffffff (RGB)
* #ffffffff (ARGB)
* RGB
* rgb\(([\d]+),\s*([\d]+),\s*([\d]+)\)
* e.g. rgb(255, 255, 255)
* RGBA
* rgba\(([\d]+),\s*([\d]+),\s*([\d]+),\s*([\d.]+)\)
* e.g. rgba(255, 255, 255, 1.0)
* HSL
* hsl\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%\)
* e.g. hsl(200, 20%, 50%)
* HSLA
* hsla\((-?[\d.]+),\s*([\d.]+)%,\s*([\d.]+)%,\s*([\d.]+)\)
* e.g. hsla(200, 20%, 50%, 0.5)
* Color name
* Options are listed in [SkParseColor.cpp](https://source.chromium.org/chromium/chromium/src/+/main:third_party/skia/src/utils/SkParseColor.cpp;l=11-152;drc=eea4bf52cb0d55e2a39c828b017c80a5ee054148)
* Similar to CSS Color Module Level 3 keywords, but case-sensitive.

`floating`, `torn-off-menu`, `modal-panel`, `main-menu`, `status`,
`pop-up-menu`, `screen-saver`, and ~~`dock`~~ (Deprecated). The default is
`floating` when `flag` is true. The `level` is reset to `normal` when the
flag is false. Note that from `floating` to `status` included, the window is
placed below the Dock on macOS and below the taskbar on Windows. From
`pop-up-menu` to a higher it is shown above the Dock on macOS and above the
taskbar on Windows. See the [macOS docs][window-levels] for more details.
* `relativeLevel` Integer (optional) _macOS_ - The number of layers higher to set
this window relative to the given `level`. The default is `0`. Note that Apple

under this mode apps can choose to optimize their UI for tablets, such as
enlarging the titlebar and hiding titlebar buttons.
This API returns whether the window is in tablet mode, and the `resize` event
can be be used to listen to changes to tablet mode.
#### `win.getMediaSourceId()`
Returns `string` - Window id in the format of DesktopCapturerSource's id. For example "window:1324:0".
More precisely the format is `window:id:other_id` where `id` is `HWND` on
Windows, `CGWindowID` (`uint64_t`) on macOS and `Window` (`unsigned long`) on
Linux. `other_id` is used to identify web contents (tabs) so within the same
top level window.
#### `win.getNativeWindowHandle()`
Returns `Buffer` - The platform-specific handle of the window.
The native type of the handle is `HWND` on Windows, `NSView*` on macOS, and

if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Same as [`webContents.loadURL(url[, options])`](web-contents.md#contentsloadurlurl-options).
The `url` can be a remote address (e.g. `http://`) or a path to a local
HTML file using the `file://` protocol.
To ensure that file URLs are properly formatted, it is recommended to use
Node's [`url.format`](https://nodejs.org/api/url.html#url_url_format_urlobject)
method:
```javascript
const url = require('url').format({
protocol: 'file',
slashes: true,
pathname: require('path').join(__dirname, 'index.html')
})
win.loadURL(url)
```
You can load a URL using a `POST` request with URL-encoded data by doing
the following:
```javascript
win.loadURL('http://localhost:8000/post', {
postData: [{
type: 'rawData',
bytes: Buffer.from('hello=world')
}],
extraHeaders: 'Content-Type: application/x-www-form-urlencoded'
})
```

Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Same as `webContents.loadFile`, `filePath` should be a path to an HTML
file relative to the root of your application. See the `webContents` docs
for more information.

Remove progress bar when progress < 0;
Change to indeterminate mode when progress > 1.
On Linux platform, only supports Unity desktop environment, you need to specify
the `*.desktop` file name to `desktopName` field in `package.json`. By default,
it will assume `{app.name}.desktop`.
On Windows, a mode can be passed. Accepted values are `none`, `normal`,
`indeterminate`, `error`, and `paused`. If you call `setProgressBar` without a
mode set (but with a value within the valid range), `normal` will be assumed.
#### `win.setOverlayIcon(overlay, description)` _Windows_

Linux, always returns 1.
#### `win.setShape(rects)` _Windows_ _Linux_ _Experimental_
* `rects` [Rectangle[]](structures/rectangle.md) - Sets a shape on the window.
Passing an empty list reverts the window to being rectangular.
Setting a window shape determines the area within the window where the system
permits drawing and user interaction. Outside of the given region, no pixels
will be drawn and no mouse events will be registered. Mouse events outside of
the region will not be received by that window, but will fall through to
whatever is behind the window.
#### `win.setThumbarButtons(buttons)` _Windows_
* `buttons` [ThumbarButton[]](structures/thumbar-button.md)
Returns `boolean` - Whether the buttons were added successfully
Add a thumbnail toolbar with a specified set of buttons to the thumbnail image
of a window in a taskbar button layout. Returns a `boolean` object indicates
whether the thumbnail has been added successfully.
The number of buttons in thumbnail toolbar should be no greater than 7 due to
the limited room. Once you setup the thumbnail toolbar, the toolbar cannot be
removed due to the platform's limitation. But you can call the API with an empty
array to clean the buttons.
The `buttons` is an array of `Button` objects:
* `Button` Object

indicating it will not respond to user action.
* `dismissonclick` - When the button is clicked, the thumbnail window closes
immediately.
* `nobackground` - Do not draw a button border, use only the image.
* `hidden` - The button is not shown to the user.
* `noninteractive` - The button is enabled but not interactive; no pressed
button state is drawn. This value is intended for instances where the button
is used in a notification.
#### `win.setThumbnailClip(region)` _Windows_
* `region` [Rectangle](structures/rectangle.md) - Region of the window
Sets the region of the window to show as the thumbnail image displayed when
hovering over the window in the taskbar. You can reset the thumbnail to be
the entire window by specifying an empty region:
`{ x: 0, y: 0, width: 0, height: 0 }`.

* `visibleOnFullScreen` boolean (optional) _macOS_ - Sets whether
the window should be visible above fullscreen windows.
* `skipTransformProcessType` boolean (optional) _macOS_ - Calling
setVisibleOnAllWorkspaces will by default transform the process
type between UIElementApplication and ForegroundApplication to
ensure the correct behavior. However, this will hide the window
and dock for a short time every time it is called. If your window
is already of type UIElementApplication, you can bypass this
transformation by passing true to skipTransformProcessType.
Sets whether the window should be visible on all workspaces.
**Note:** This API does nothing on Windows.
#### `win.isVisibleOnAllWorkspaces()` _macOS_ _Linux_
Returns `boolean` - Whether the window is visible on all workspaces.
**Note:** This API always returns false on Windows.
#### `win.setIgnoreMouseEvents(ignore[, options])`
* `ignore` boolean
* `options` Object (optional)
* `forward` boolean (optional) _macOS_ _Windows_ - If true, forwards mouse move
messages to Chromium, enabling mouse related events such as `mouseleave`.
Only used when `ignore` is true. If `ignore` is false, forwarding is always
disabled regardless of this value.
Makes the window ignore all mouse events.
All mouse events happened in this window will be passed to the window below
this window, but if this window has focus, it will still receive keyboard
events.
#### `win.setContentProtection(enable)` _macOS_ _Windows_
* `enable` boolean
Prevents the window contents from being captured by other apps.
On macOS it sets the NSWindow's sharingType to NSWindowSharingNone.
On Windows it calls SetWindowDisplayAffinity with `WDA_EXCLUDEFROMCAPTURE`.
For Windows 10 version 2004 and up the window will be removed from capture entirely,
older Windows versions behave as if `WDA_MONITOR` is applied capturing a black window.

will remove the vibrancy effect on the window.
Note that `appearance-based`, `light`, `dark`, `medium-light`, and `ultra-dark` have been
deprecated and will be removed in an upcoming version of macOS.
#### `win.setTrafficLightPosition(position)` _macOS_
* `position` [Point](structures/point.md)
Set a custom position for the traffic light buttons in frameless window.
#### `win.getTrafficLightPosition()` _macOS_
Returns `Point` - The custom position for the traffic light buttons in
frameless window.
#### `win.setTouchBar(touchBar)` _macOS_
* `touchBar` TouchBar | null
Sets the touchBar layout for the current window. Specifying `null` or
`undefined` clears the touch bar. This method only has an effect if the
machine has a touch bar and is running on macOS 10.12.1+.
**Note:** The TouchBar API is currently experimental and may change or be
removed in future Electron releases.
#### `win.setBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md) | null - Attach `browserView` to `win`.
If there are other `BrowserView`s attached, they will be removed from
this window.
#### `win.getBrowserView()` _Experimental_
Returns `BrowserView | null` - The `BrowserView` attached to `win`. Returns `null`
if one is not attached. Throws an error if multiple `BrowserView`s are attached.
#### `win.addBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md)
Replacement API for setBrowserView supporting work with multi browser views.
#### `win.removeBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md)
#### `win.setTopBrowserView(browserView)` _Experimental_
* `browserView` [BrowserView](browser-view.md)
Raises `browserView` above other `BrowserView`s attached to `win`.
Throws an error if `browserView` is not attached to `win`.
#### `win.getBrowserViews()` _Experimental_
Returns `BrowserView[]` - an array of all BrowserViews that have been attached
with `addBrowserView` or `setBrowserView`.
**Note:** The BrowserView API is currently experimental and may change or be
removed in future Electron releases.
#### `win.setTitleBarOverlay(options)` _Windows_
* `options` Object
* `color` String (optional) _Windows_ - The CSS color of the Window Controls Overlay when enabled.
* `symbolColor` String (optional) _Windows_ - The CSS color of the symbols on the Window Controls Overlay when enabled.
* `height` Integer (optional) _Windows_ - The height of the title bar and Window Controls Overlay in pixels.
On a Window with Window Controls Overlay already enabled, this method updates
the style of the title bar overlay.

# Chrome Extension Support
Electron supports a subset of the [Chrome Extensions
API][chrome-extensions-api-index], primarily to support DevTools extensions and
Chromium-internal extensions, but it also happens to support some other
extension capabilities.
[chrome-extensions-api-index]: https://developer.chrome.com/extensions/api_index
> **Note:** Electron does not support arbitrary Chrome extensions from the
> store, and it is a **non-goal** of the Electron project to be perfectly
> compatible with Chrome's implementation of Extensions.
## Loading extensions
Electron only supports loading unpacked extensions (i.e., `.crx` files do not
work). Extensions are installed per-`session`. To load an extension, call
[`ses.loadExtension`](session.md#sesloadextensionpath-options):
```js
const { session } = require('electron')
session.loadExtension('path/to/unpacked/extension').then(({ id }) => {
// ...
})
```
Loaded extensions will not be automatically remembered across exits; if you do
not call `loadExtension` when the app runs, the extension will not be loaded.
Note that loading extensions is only supported in persistent sessions.
Attempting to load an extension into an in-memory session will throw an error.
See the [`session`](session.md) documentation for more information about
loading, unloading, and querying active extensions.
## Supported Extensions APIs
We support the following extensions APIs, with some caveats. Other APIs may
additionally be supported, but support for any APIs not listed here is
provisional and may be removed.
### `chrome.devtools.inspectedWindow`
All features of this API are supported.
### `chrome.devtools.network`
All features of this API are supported.
### `chrome.devtools.panels`
All features of this API are supported.
### `chrome.extension`
The following properties of `chrome.extension` are supported:
- `chrome.extension.lastError`
The following methods of `chrome.extension` are supported:
- `chrome.extension.getURL`
- `chrome.extension.getBackgroundPage`
### `chrome.runtime`
The following properties of `chrome.runtime` are supported:
- `chrome.runtime.lastError`
- `chrome.runtime.id`
The following methods of `chrome.runtime` are supported:
- `chrome.runtime.getBackgroundPage`
- `chrome.runtime.getManifest`
- `chrome.runtime.getPlatformInfo`
- `chrome.runtime.getURL`
- `chrome.runtime.connect`
- `chrome.runtime.sendMessage`
- `chrome.runtime.reload`
The following events of `chrome.runtime` are supported:
- `chrome.runtime.onStartup`
- `chrome.runtime.onInstalled`
- `chrome.runtime.onSuspend`
- `chrome.runtime.onSuspendCanceled`
- `chrome.runtime.onConnect`
- `chrome.runtime.onMessage`
### `chrome.storage`
Only `chrome.storage.local` is supported; `chrome.storage.sync` and
`chrome.storage.managed` are not.
### `chrome.tabs`
The following methods of `chrome.tabs` are supported:
- `chrome.tabs.sendMessage`
- `chrome.tabs.executeScript`
- `chrome.tabs.update` (partial support)
- supported properties: `url`, `muted`.
> **Note:** In Chrome, passing `-1` as a tab ID signifies the "currently active
> tab". Since Electron has no such concept, passing `-1` as a tab ID is not
> supported and will raise an error.
### `chrome.management`
The following methods of `chrome.management` are supported:
- `chrome.management.getAll`
- `chrome.management.get`
- `chrome.management.getSelf`
- `chrome.management.getPermissionWarningsById`
- `chrome.management.getPermissionWarningsByManifest`
- `chrome.management.onEnabled`
- `chrome.management.onDisabled`
### `chrome.webRequest`
All features of this API are supported.
> **NOTE:** Electron's [`webRequest`](web-request.md) module takes precedence over `chrome.webRequest` if there are conflicting handlers.

### What operating system are you using?
macOS
### Operating System Version
MacOS 12.3
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
PDF File should be displayed just like when opening the page in Chrome browser.
### Actual Behavior
The PDF file isn't displayed in the Embed.
Screenshot:
=> Error loading PDF document.
### Testcase Gist URL
_No response_
### Additional Information
I use this html for displaying it:
`<embed type="application/pdf" src="https://....." style="width: 100%; height: 30rem;">`
The document URL in here is a Blob URL with a PDF fetched from an internal API.
The window is loaded using this code:
```
const { app, BrowserWindow } = require('electron')
const createWindow = () => {
const win = new BrowserWindow({
width: 1400,
height: 800,
webPreferences: {

# Chrome Extension Support
Electron supports a subset of the [Chrome Extensions
API][chrome-extensions-api-index], primarily to support DevTools extensions and
Chromium-internal extensions, but it also happens to support some other
extension capabilities.
[chrome-extensions-api-index]: https://developer.chrome.com/extensions/api_index
> **Note:** Electron does not support arbitrary Chrome extensions from the
> store, and it is a **non-goal** of the Electron project to be perfectly
> compatible with Chrome's implementation of Extensions.
## Loading extensions
Electron only supports loading unpacked extensions (i.e., `.crx` files do not
work). Extensions are installed per-`session`. To load an extension, call
[`ses.loadExtension`](session.md#sesloadextensionpath-options):
```js
const { session } = require('electron')
session.loadExtension('path/to/unpacked/extension').then(({ id }) => {
// ...
})
```
Loaded extensions will not be automatically remembered across exits; if you do
not call `loadExtension` when the app runs, the extension will not be loaded.
Note that loading extensions is only supported in persistent sessions.
Attempting to load an extension into an in-memory session will throw an error.
See the [`session`](session.md) documentation for more information about
loading, unloading, and querying active extensions.
## Supported Extensions APIs
We support the following extensions APIs, with some caveats. Other APIs may
additionally be supported, but support for any APIs not listed here is
provisional and may be removed.
### `chrome.devtools.inspectedWindow`
All features of this API are supported.
### `chrome.devtools.network`
All features of this API are supported.
### `chrome.devtools.panels`
All features of this API are supported.
### `chrome.extension`
The following properties of `chrome.extension` are supported:
- `chrome.extension.lastError`
The following methods of `chrome.extension` are supported:
- `chrome.extension.getURL`
- `chrome.extension.getBackgroundPage`
### `chrome.runtime`
The following properties of `chrome.runtime` are supported:
- `chrome.runtime.lastError`
- `chrome.runtime.id`
The following methods of `chrome.runtime` are supported:
- `chrome.runtime.getBackgroundPage`
- `chrome.runtime.getManifest`
- `chrome.runtime.getPlatformInfo`
- `chrome.runtime.getURL`
- `chrome.runtime.connect`
- `chrome.runtime.sendMessage`
- `chrome.runtime.reload`
The following events of `chrome.runtime` are supported:
- `chrome.runtime.onStartup`
- `chrome.runtime.onInstalled`
- `chrome.runtime.onSuspend`
- `chrome.runtime.onSuspendCanceled`
- `chrome.runtime.onConnect`
- `chrome.runtime.onMessage`
### `chrome.storage`
Only `chrome.storage.local` is supported; `chrome.storage.sync` and
`chrome.storage.managed` are not.
### `chrome.tabs`
The following methods of `chrome.tabs` are supported:
- `chrome.tabs.sendMessage`
- `chrome.tabs.executeScript`
- `chrome.tabs.update` (partial support)
- supported properties: `url`, `muted`.
> **Note:** In Chrome, passing `-1` as a tab ID signifies the "currently active
> tab". Since Electron has no such concept, passing `-1` as a tab ID is not
> supported and will raise an error.
### `chrome.management`
The following methods of `chrome.management` are supported:
- `chrome.management.getAll`
- `chrome.management.get`
- `chrome.management.getSelf`
- `chrome.management.getPermissionWarningsById`
- `chrome.management.getPermissionWarningsByManifest`
- `chrome.management.onEnabled`
- `chrome.management.onDisabled`
### `chrome.webRequest`
All features of this API are supported.
> **NOTE:** Electron's [`webRequest`](web-request.md) module takes precedence over `chrome.webRequest` if there are conflicting handlers.

### What operating system are you using?
macOS
### Operating System Version
MacOS 12.3
### What arch are you using?

PDF File should be displayed just like when opening the page in Chrome browser.
### Actual Behavior
The PDF file isn't displayed in the Embed.
Screenshot:
=> Error loading PDF document.
### Testcase Gist URL
_No response_
### Additional Information
I use this html for displaying it:
`<embed type="application/pdf" src="https://....." style="width: 100%; height: 30rem;">`
The document URL in here is a Blob URL with a PDF fetched from an internal API.
The window is loaded using this code:
```
const { app, BrowserWindow } = require('electron')
const createWindow = () => {
const win = new BrowserWindow({
width: 1400,
height: 800,
webPreferences: {
plugins: true
}
})
win.loadURL("https://127.0.0.1:8000/app")
}
app.whenReady().then(() => {
createWindow()
})
```

[Bug]: safeStorage.isEncryptionAvailable() returns false in Windows
|
### Preflight Checklist

### Electron Version
17.1.0 and 18.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Version 21H1
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
According to the safeStorage module documentation (https://www.electronjs.org/docs/latest/api/safe-storage) `safeStorage.isEncryptionAvailable()` should return `true` "with no other preconditions."
### Actual Behavior
I have been working on an Electron app in Electron v17.1.0. `safeStorage.isEncryptionAvailable()` returns `false` in my tests, so I have been unable to use the safeStorage module.
To ensure that it wasn't something about my application (which I don't have any reason to believe), I created a new Electron project following the latest quick start guide (https://www.electronjs.org/docs/latest/tutorial/quick-start) using Electron v18.0.2. Still, `safeStorage.isEncryptionAvailable()` returns `false`.
If I try `safeStorage.encryptString("hello");` I get this error on `npm start`
```
App threw an error during load
Error: Error while decrypting the ciphertext provided to safeStorage.decryptString. Encryption is not available.
at Object.<anonymous> (C:\Users\...\Node Projects\!projects\electron-quick-start\test-safeStorage.js:4:13)
at Module._compile (node:internal/modules/cjs/loader:1116:14)
at Object.Module._extensions..js (node:internal/modules/cjs/loader:1169:10)
at Module.load (node:internal/modules/cjs/loader:988:32)
at Module._load (node:internal/modules/cjs/loader:829:12)
at Function.c._load (node:electron/js2c/asar_bundle:5:13343)
at Module.require (node:internal/modules/cjs/loader:1012:19)
at require (node:internal/modules/cjs/helpers:102:18)
at Object.<anonymous> (C:\Users\...\Node Projects\!projects\electron-quick-start\main.js:48:1)
at Module._compile (node:internal/modules/cjs/loader:1116:14)
```
Here are the entire contents of my `test-safeStorage.js` module:
```
const { safeStorage } = require("electron");
console.log(safeStorage.isEncryptionAvailable());
safeStorage.encryptString("hello");
```
Which I am simply requiring in `main.js` with `require("./test-safeStorage.js");`
### Testcase Gist URL
_No response_
### Additional Information
Could it be something about my Windows config that is causing this?
I have tried running `npm start` from both unprivileged PowerShell sessions and PowerShell sessions with administrative rights.

# safeStorage
> Allows access to simple encryption and decryption of strings for storage on the local machine.
Process: [Main](../glossary.md#main-process)
This module protects data stored on disk from being accessed by other applications or users with full disk access.
Note that on Mac, access to the system Keychain is required and
these calls can block the current thread to collect user input.
The same is true for Linux, if a password management tool is available.
## Methods
The `safeStorage` module has the following methods:
### `safeStorage.isEncryptionAvailable()`
Returns `boolean` - Whether encryption is available.
On Linux, returns true if the secret key is
available. On MacOS, returns true if Keychain is available.
On Windows, returns true with no other preconditions.
### `safeStorage.encryptString(plainText)`
* `plainText` string

[Bug]: safeStorage.isEncryptionAvailable() returns false in Windows
|
### Preflight Checklist

### Electron Version
17.1.0 and 18.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Version 21H1
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
According to the safeStorage module documentation (https://www.electronjs.org/docs/latest/api/safe-storage) `safeStorage.isEncryptionAvailable()` should return `true` "with no other preconditions."
### Actual Behavior
I have been working on an Electron app in Electron v17.1.0. `safeStorage.isEncryptionAvailable()` returns `false` in my tests, so I have been unable to use the safeStorage module.
To ensure that it wasn't something about my application (which I don't have any reason to believe), I created a new Electron project following the latest quick start guide (https://www.electronjs.org/docs/latest/tutorial/quick-start) using Electron v18.0.2. Still, `safeStorage.isEncryptionAvailable()` returns `false`.
If I try `safeStorage.encryptString("hello");` I get this error on `npm start`
```
App threw an error during load
Error: Error while decrypting the ciphertext provided to safeStorage.decryptString. Encryption is not available.

at Module._compile (node:internal/modules/cjs/loader:1116:14)
```
Here are the entire contents of my `test-safeStorage.js` module:
```
const { safeStorage } = require("electron");
console.log(safeStorage.isEncryptionAvailable());
safeStorage.encryptString("hello");
```
Which I am simply requiring in `main.js` with `require("./test-safeStorage.js");`
### Testcase Gist URL
_No response_
### Additional Information
Could it be something about my Windows config that is causing this?
I have tried running `npm start` from both unprivileged PowerShell sessions and PowerShell sessions with administrative rights.

# safeStorage
> Allows access to simple encryption and decryption of strings for storage on the local machine.
Process: [Main](../glossary.md#main-process)
This module protects data stored on disk from being accessed by other applications or users with full disk access.
Note that on Mac, access to the system Keychain is required and
these calls can block the current thread to collect user input.
The same is true for Linux, if a password management tool is available.
## Methods
The `safeStorage` module has the following methods:
### `safeStorage.isEncryptionAvailable()`
Returns `boolean` - Whether encryption is available.
On Linux, returns true if the secret key is
available. On MacOS, returns true if Keychain is available.
On Windows, returns true with no other preconditions.
### `safeStorage.encryptString(plainText)`
* `plainText` string
Returns `Buffer` - An array of bytes representing the encrypted string.
This function will throw an error if encryption fails.
### `safeStorage.decryptString(encrypted)`
* `encrypted` Buffer
Returns `string` - the decrypted string. Decrypts the encrypted buffer
obtained with `safeStorage.encryptString` back into a string.
This function will throw an error if decryption fails.

* `callback` Function
* `event` string
* `userInfo` Record<string, unknown>
* `object` string
Returns `number` - The ID of this subscription
Subscribes to native notifications of macOS, `callback` will be called with
`callback(event, userInfo)` when the corresponding `event` happens. The
`userInfo` is an Object that contains the user information dictionary sent
along with the notification. The `object` is the sender of the notification,
and only supports `NSString` values for now.
The `id` of the subscriber is returned, which can be used to unsubscribe the
`event`.
Under the hood this API subscribes to `NSDistributedNotificationCenter`,
example values of `event` are:
* `AppleInterfaceThemeChangedNotification`
* `AppleAquaColorVariantChanged`
* `AppleColorPreferencesChangedNotification`
* `AppleShowScrollBarsSettingChanged`
### `systemPreferences.subscribeLocalNotification(event, callback)` _macOS_
* `event` string
* `callback` Function
* `event` string
* `userInfo` Record<string, unknown>
* `object` string
Returns `number` - The ID of this subscription
Same as `subscribeNotification`, but uses `NSNotificationCenter` for local defaults.
This is necessary for events such as `NSUserDefaultsDidChangeNotification`.

* `event` string
* `callback` Function
* `event` string
* `userInfo` Record<string, unknown>
* `object` string
Returns `number` - The ID of this subscription
Same as `subscribeNotification`, but uses `NSWorkspace.sharedWorkspace.notificationCenter`.
This is necessary for events such as `NSWorkspaceDidActivateApplicationNotification`.
### `systemPreferences.unsubscribeNotification(id)` _macOS_
* `id` Integer
Removes the subscriber with `id`.
### `systemPreferences.unsubscribeLocalNotification(id)` _macOS_
* `id` Integer
Same as `unsubscribeNotification`, but removes the subscriber from `NSNotificationCenter`.
### `systemPreferences.unsubscribeWorkspaceNotification(id)` _macOS_
* `id` Integer
Same as `unsubscribeNotification`, but removes the subscriber from `NSWorkspace.sharedWorkspace.notificationCenter`.
### `systemPreferences.registerDefaults(defaults)` _macOS_
* `defaults` Record<string, string | boolean | number> - a dictionary of (`key: value`) user defaults
Add the specified defaults to your application's `NSUserDefaults`.
### `systemPreferences.getUserDefault<Type extends keyof UserDefaultTypes>(key, type)` _macOS_
* `key` string
* `type` Type - Can be `string`, `boolean`, `integer`, `float`, `double`,
`url`, `array` or `dictionary`.
Returns [`UserDefaultTypes[Type]`](structures/user-default-types.md) - The value of `key` in `NSUserDefaults`.
Some popular `key` and `type`s are:
* `AppleInterfaceStyle`: `string`
* `AppleAquaColorVariant`: `integer`
* `AppleHighlightColor`: `string`
* `AppleShowScrollBars`: `string`
* `NSNavRecentPlaces`: `array`

Set the value of `key` in `NSUserDefaults`.
Note that `type` should match actual type of `value`. An exception is thrown
if they don't.
Some popular `key` and `type`s are:
* `ApplePressAndHoldEnabled`: `boolean`
### `systemPreferences.removeUserDefault(key)` _macOS_
* `key` string
Removes the `key` in `NSUserDefaults`. This can be used to restore the default
or global value of a `key` previously set with `setUserDefault`.
### `systemPreferences.isAeroGlassEnabled()` _Windows_
Returns `boolean` - `true` if [DWM composition][dwm-composition] (Aero Glass) is
enabled, and `false` otherwise.
An example of using it to determine if you should create a transparent window or
not (transparent windows won't work correctly when DWM composition is disabled):
```javascript
const { BrowserWindow, systemPreferences } = require('electron')
const browserOptions = { width: 1000, height: 800 }
// Make the window transparent only if the platform supports it.
if (process.platform !== 'win32' || systemPreferences.isAeroGlassEnabled()) {
browserOptions.transparent = true
browserOptions.frame = false
}
// Create the window.
const win = new BrowserWindow(browserOptions)
// Navigate.
if (browserOptions.transparent) {
win.loadURL(`file://${__dirname}/index.html`)
} else {
// No transparency, so we load a fallback that uses basic styles.
win.loadURL(`file://${__dirname}/fallback.html`)
}
```
[dwm-composition]:https://msdn.microsoft.com/en-us/library/windows/desktop/aa969540.aspx

See [Apple Documentation](https://developer.apple.com/design/human-interface-guidelines/macos/visual-design/color#system-colors) for more details.
### `systemPreferences.isInvertedColorScheme()` _Windows_ _Deprecated_
Returns `boolean` - `true` if an inverted color scheme (a high contrast color scheme with light text and dark backgrounds) is active, `false` otherwise.
**Deprecated:** Should use the new [`nativeTheme.shouldUseInvertedColorScheme`](native-theme.md#nativethemeshoulduseinvertedcolorscheme-macos-windows-readonly) API.
### `systemPreferences.isHighContrastColorScheme()` _macOS_ _Windows_ _Deprecated_

### `systemPreferences.getEffectiveAppearance()` _macOS_
Returns `string` - Can be `dark`, `light` or `unknown`.
Gets the macOS appearance setting that is currently applied to your application,
maps to [NSApplication.effectiveAppearance](https://developer.apple.com/documentation/appkit/nsapplication/2967171-effectiveappearance?language=objc)
### `systemPreferences.getAppLevelAppearance()` _macOS_ _Deprecated_
Returns `string` | `null` - Can be `dark`, `light` or `unknown`.
Gets the macOS appearance setting that you have declared you want for
your application, maps to [NSApplication.appearance](https://developer.apple.com/documentation/appkit/nsapplication/2967170-appearance?language=objc).
You can use the `setAppLevelAppearance` API to set this value.
### `systemPreferences.setAppLevelAppearance(appearance)` _macOS_ _Deprecated_
* `appearance` string | null - Can be `dark` or `light`
Sets the appearance setting for your application, this should override the
system default and override the value of `getEffectiveAppearance`.
### `systemPreferences.canPromptTouchID()` _macOS_
Returns `boolean` - whether or not this device has the ability to use Touch ID.
**NOTE:** This API will return `false` on macOS systems older than Sierra 10.12.2.
### `systemPreferences.promptTouchID(reason)` _macOS_
* `reason` string - The reason you are asking for Touch ID authentication
Returns `Promise<void>` - resolves if the user has successfully authenticated with Touch ID.
```javascript
const { systemPreferences } = require('electron')
systemPreferences.promptTouchID('To get consent for a Security-Gated Thing').then(success => {
console.log('You have successfully authenticated with Touch ID!')
}).catch(err => {
console.log(err)
})
```
This API itself will not protect your user data; rather, it is a mechanism to allow you to do so. Native apps will need to set [Access Control Constants](https://developer.apple.com/documentation/security/secaccesscontrolcreateflags?language=objc) like [`kSecAccessControlUserPresence`](https://developer.apple.com/documentation/security/secaccesscontrolcreateflags/ksecaccesscontroluserpresence?language=objc) on their keychain entry so that reading it would auto-prompt for Touch ID biometric consent. This could be done with [`node-keytar`](https://github.com/atom/node-keytar), such that one would store an encryption key with `node-keytar` and only fetch it if `promptTouchID()` resolves.
**NOTE:** This API will return a rejected Promise on macOS systems older than Sierra 10.12.2.
### `systemPreferences.isTrustedAccessibilityClient(prompt)` _macOS_
* `prompt` boolean - whether or not the user will be informed via prompt if the current process is untrusted.
Returns `boolean` - `true` if the current process is a trusted accessibility client and `false` if it is not.
### `systemPreferences.getMediaAccessStatus(mediaType)` _Windows_ _macOS_
* `mediaType` string - Can be `microphone`, `camera` or `screen`.
Returns `string` - Can be `not-determined`, `granted`, `denied`, `restricted` or `unknown`.
This user consent was not required on macOS 10.13 High Sierra or lower so this method will always return `granted`.
macOS 10.14 Mojave or higher requires consent for `microphone` and `camera` access.
macOS 10.15 Catalina or higher requires consent for `screen` access.
Windows 10 has a global setting controlling `microphone` and `camera` access for all win32 applications.
It will always return `granted` for `screen` and for all media types on older versions of Windows.
### `systemPreferences.askForMediaAccess(mediaType)` _macOS_
* `mediaType` string - the type of media being requested; can be `microphone`, `camera`.
Returns `Promise<boolean>` - A promise that resolves with `true` if consent was granted and `false` if it was denied. If an invalid `mediaType` is passed, the promise will be rejected. If an access request was denied and later is changed through the System Preferences pane, a restart of the app will be required for the new permissions to take effect. If access has already been requested and denied, it _must_ be changed through the preference pane; an alert will not pop up and the promise will resolve with the existing access status.
**Important:** In order to properly leverage this API, you [must set](https://developer.apple.com/documentation/avfoundation/cameras_and_media_capture/requesting_authorization_for_media_capture_on_macos?language=objc) the `NSMicrophoneUsageDescription` and `NSCameraUsageDescription` strings in your app's `Info.plist` file. The values for these keys will be used to populate the permission dialogs so that the user will be properly informed as to the purpose of the permission request. See [Electron Application Distribution](../tutorial/application-distribution.md#macos) for more information about how to set these in the context of Electron.
This user consent was not required until macOS 10.14 Mojave, so this method will always return `true` if your system is running 10.13 High Sierra or lower.
### `systemPreferences.getAnimationSettings()`
Returns `Object`:
* `shouldRenderRichAnimation` boolean - Returns true if rich animations should be rendered. Looks at session type (e.g. remote desktop) and accessibility settings to give guidance for heavy animations.
* `scrollAnimationsEnabledBySystem` boolean - Determines on a per-platform basis whether scroll animations (e.g. produced by home/end key) should be enabled.
* `prefersReducedMotion` boolean - Determines whether the user desires reduced motion based on platform APIs.
Returns an object with system animation settings.
## Properties
### `systemPreferences.appLevelAppearance` _macOS_
A `string` property that can be `dark`, `light` or `unknown`. It determines the macOS appearance setting for
your application. This maps to values in: [NSApplication.appearance](https://developer.apple.com/documentation/appkit/nsapplication/2967170-appearance?language=objc). Setting this will override the
system default as well as the value of `getEffectiveAppearance`.
Possible values that can be set are `dark` and `light`, and possible return values are `dark`, `light`, and `unknown`.
This property is only available on macOS 10.14 Mojave or newer.
### `systemPreferences.effectiveAppearance` _macOS_ _Readonly_
A `string` property that can be `dark`, `light` or `unknown`.
Returns the macOS appearance setting that is currently applied to your application,
maps to [NSApplication.effectiveAppearance](https://developer.apple.com/documentation/appkit/nsapplication/2967171-effectiveappearance?language=objc)

It is obvious that `SysUTF8ToNSString(name)` will throw an error when name is `nil`. `nil` is a valid input.
```
