Add 'focus' & 'blur' events to BrowserView/WebContents
|
### 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 a feature request that matches the one I want to file, without success.
### Problem Description
When working with BrowserViews, there's no way to listen to focus changes on either BrowserView itself or its WebContents.
### Proposed Solution
On BrowserWindow, there are `focus` and `blur` events. The same events need to be emitted on BrowserView/WebContents.
i.e. :
```
browserView.on('focus', () => {
// view is focused, do stuff
});
```
or
```
browserView.webContents.on('focus', () => {
// contents are focused, do stuff
});
```
### Alternatives Considered
I can't think of a good way of working around this lack of functionality

Subject: printing.patch
Add changeset that was previously applied to sources in chromium_src. The
majority of changes originally come from these PRs:
* https://github.com/electron/electron/pull/1835
* https://github.com/electron/electron/pull/8596
This patch also fixes callback for manual user cancellation and success.

[Bug]: Windows Control Overlay button hover effect not working

### Electron Version
14.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
See https://github.com/electron/electron/issues/30764 for specific behavior
### Actual Behavior
See https://github.com/electron/electron/issues/30764 for specific behavior
### Testcase Gist URL
_No response_
### Additional Information
I am creating this issue based on https://github.com/electron/electron/issues/30764 and the information I have gathered while trying to triage it. Though this not a breaking bug, it does create a visual inconsistency for users, as a window control button would typically change color when hovered over. For this reason, I think it should still be addressed at some point. Consolidating all current information and future questions/comments here should help in finding a solution.
[Here](https://bugs.chromium.org/p/chromium/issues/detail?id=1218921) is a link to the bug that led to the original fix implemented in Chromium
And [here](https://bugs.chromium.org/p/chromium/issues/detail?id=1271293#c1) is the link to the follow-up bug report created noting issues with the implemented fix. This was then labeled as `WontFix`
The chromium fix artificially creates the correct tooltips and allows for the button color to change on hover. However, this results in a response to the `WM_NCHITTEST` [message](https://docs.microsoft.com/en-us/windows/win32/inputdev/wm-nchittest) that does not correspond with the function of the button. For example, `HTMAXIMIZE` is not returned, thus Snap Layout on Windows 11 does not work.
If someone else wants to take a look at this, the relevant Electron files can be found in [this PR](https://github.com/electron/electron/pull/29600) adding WCO to Electron. For this bug in particular, I believe the related files are: `shell/browser/ui/views/win_caption_button.cc`, `shell/browser/ui/views/win_caption_button_container.cc`, and `shell/browser/ui/views/win_frame_view.cc` but changes to other files may provide a solution as well.

[Bug]: Windows Control Overlay button hover effect not working
|
### 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
14.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
See https://github.com/electron/electron/issues/30764 for specific behavior
### Actual Behavior
See https://github.com/electron/electron/issues/30764 for specific behavior
### Testcase Gist URL
_No response_
### Additional Information
I am creating this issue based on https://github.com/electron/electron/issues/30764 and the information I have gathered while trying to triage it. Though this not a breaking bug, it does create a visual inconsistency for users, as a window control button would typically change color when hovered over. For this reason, I think it should still be addressed at some point. Consolidating all current information and future questions/comments here should help in finding a solution.
[Here](https://bugs.chromium.org/p/chromium/issues/detail?id=1218921) is a link to the bug that led to the original fix implemented in Chromium
And [here](https://bugs.chromium.org/p/chromium/issues/detail?id=1271293#c1) is the link to the follow-up bug report created noting issues with the implemented fix. This was then labeled as `WontFix`
The chromium fix artificially creates the correct tooltips and allows for the button color to change on hover. However, this results in a response to the `WM_NCHITTEST` [message](https://docs.microsoft.com/en-us/windows/win32/inputdev/wm-nchittest) that does not correspond with the function of the button. For example, `HTMAXIMIZE` is not returned, thus Snap Layout on Windows 11 does not work.
If someone else wants to take a look at this, the relevant Electron files can be found in [this PR](https://github.com/electron/electron/pull/29600) adding WCO to Electron. For this bug in particular, I believe the related files are: `shell/browser/ui/views/win_caption_button.cc`, `shell/browser/ui/views/win_caption_button_container.cc`, and `shell/browser/ui/views/win_frame_view.cc` but changes to other files may provide a solution as well.

Update deprecated QuickLook Thumbnailing methods
|
Nearly all methods we use in `nativeImage.createThumbnailFromPath()` are deprecated on macOS as of 10.15 and scheduled for imminent removal - we should update our usage of those methods to the newer `QuickLookThumbnailing` framework accordingly.
See [here](https://developer.apple.com/documentation/quicklook/previews_or_thumbnail_images_for_macos_10_14_or_earlier?language=objc) for deprecation information and [here](https://developer.apple.com/documentation/quicklookthumbnailing?language=objc) for the updated framework we should use.

Update deprecated QuickLook Thumbnailing methods
|
Nearly all methods we use in `nativeImage.createThumbnailFromPath()` are deprecated on macOS as of 10.15 and scheduled for imminent removal - we should update our usage of those methods to the newer `QuickLookThumbnailing` framework accordingly.
See [here](https://developer.apple.com/documentation/quicklook/previews_or_thumbnail_images_for_macos_10_14_or_earlier?language=objc) for deprecation information and [here](https://developer.apple.com/documentation/quicklookthumbnailing?language=objc) for the updated framework we should use.

Update deprecated QuickLook Thumbnailing methods
|
Nearly all methods we use in `nativeImage.createThumbnailFromPath()` are deprecated on macOS as of 10.15 and scheduled for imminent removal - we should update our usage of those methods to the newer `QuickLookThumbnailing` framework accordingly.
See [here](https://developer.apple.com/documentation/quicklook/previews_or_thumbnail_images_for_macos_10_14_or_earlier?language=objc) for deprecation information and [here](https://developer.apple.com/documentation/quicklookthumbnailing?language=objc) for the updated framework we should use.

# webContents
> Render and control web pages.
Process: [Main](../glossary.md#main-process)
`webContents` is an [EventEmitter][event-emitter].
It is responsible for rendering and controlling a web page and is a property of
the [`BrowserWindow`](browser-window.md) object. An example of accessing the
`webContents` object:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 1500 })
win.loadURL('http://github.com')
const contents = win.webContents
console.log(contents)
```
## Methods
These methods can be accessed from the `webContents` module:
```javascript
const { webContents } = require('electron')
console.log(webContents)
```
### `webContents.getAllWebContents()`
Returns `WebContents[]` - An array of all `WebContents` instances. This will contain web contents
for all windows, webviews, opened devtools, and devtools extension background pages.
### `webContents.getFocusedWebContents()`
Returns `WebContents` - The web contents that is focused in this application, otherwise
returns `null`.
### `webContents.fromId(id)`
* `id` Integer
Returns `WebContents` | undefined - A WebContents instance with the given ID, or
`undefined` if there is no WebContents associated with the given ID.
### `webContents.fromDevToolsTargetId(targetId)`
* `targetId` string - The Chrome DevTools Protocol [TargetID](https://chromedevtools.github.io/devtools-protocol/tot/Target/#type-TargetID) associated with the WebContents instance.
Returns `WebContents` | undefined - A WebContents instance with the given TargetID, or
`undefined` if there is no WebContents associated with the given TargetID.
When communicating with the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/),
it can be useful to lookup a WebContents instance based on its assigned TargetID.
```js
async function lookupTargetId (browserWindow) {
const wc = browserWindow.webContents
await wc.debugger.attach('1.3')
const { targetInfo } = await wc.debugger.sendCommand('Target.getTargetInfo')
const { targetId } = targetInfo
const targetWebContents = await webContents.fromDevToolsTargetId(targetId)
}
```
## Class: WebContents
> Render and control the contents of a BrowserWindow instance.
Process: [Main](../glossary.md#main-process)<br />
_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
### Instance Events
#### Event: 'did-finish-load'
Emitted when the navigation is done, i.e. the spinner of the tab has stopped
spinning, and the `onload` event was dispatched.
#### Event: 'did-fail-load'
Returns:
* `event` Event
* `errorCode` Integer
* `errorDescription` string
* `validatedURL` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
This event is like `did-finish-load` but emitted when the load failed.
The full list of error codes and their meaning is available [here](https://source.chromium.org/chromium/chromium/src/+/master:net/base/net_error_list.h).
#### Event: 'did-fail-provisional-load'
Returns:
* `event` Event
* `errorCode` Integer
* `errorDescription` string
* `validatedURL` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
This event is like `did-fail-load` but emitted when the load was cancelled
(e.g. `window.stop()` was invoked).
#### Event: 'did-frame-finish-load'
Returns:
* `event` Event
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when a frame has done navigation.
#### Event: 'did-start-loading'
Corresponds to the points in time when the spinner of the tab started spinning.
#### Event: 'did-stop-loading'
Corresponds to the points in time when the spinner of the tab stopped spinning.
#### Event: 'dom-ready'
Returns:
* `event` Event
Emitted when the document in the top-level frame is loaded.
#### Event: 'page-title-updated'
Returns:
* `event` Event
* `title` string
* `explicitSet` boolean
Fired when page title is set during navigation. `explicitSet` is false when
title is synthesized from file url.
#### Event: 'page-favicon-updated'
Returns:
* `event` Event
* `favicons` string[] - Array of URLs.
Emitted when page receives favicon urls.
#### Event: 'new-window' _Deprecated_
Returns:
* `event` NewWindowWebContentsEvent
* `url` string
* `frameName` string
* `disposition` string - Can be `default`, `foreground-tab`, `background-tab`,
`new-window`, `save-to-disk` and `other`.
* `options` BrowserWindowConstructorOptions - The options which will be used for creating the new
[`BrowserWindow`](browser-window.md).
* `additionalFeatures` string[] - The non-standard features (features not handled
by Chromium or Electron) given to `window.open()`. Deprecated, and will now
always be the empty array `[]`.
* `referrer` [Referrer](structures/referrer.md) - The referrer that will be
passed to the new window. May or may not result in the `Referer` header being
sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data that
will be sent to the new window, along with the appropriate headers that will
be set. If no post data is to be sent, the value will be `null`. Only defined
when the window is being created by a form that set `target=_blank`.
Deprecated in favor of [`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
Emitted when the page requests to open a new window for a `url`. It could be
requested by `window.open` or an external link like `<a target='_blank'>`.
By default a new `BrowserWindow` will be created for the `url`.
Calling `event.preventDefault()` will prevent Electron from automatically creating a
new [`BrowserWindow`](browser-window.md). If you call `event.preventDefault()` and manually create a new
[`BrowserWindow`](browser-window.md) then you must set `event.newGuest` to reference the new [`BrowserWindow`](browser-window.md)
instance, failing to do so may result in unexpected behavior. For example:
```javascript
myBrowserWindow.webContents.on('new-window', (event, url, frameName, disposition, options, additionalFeatures, referrer, postBody) => {
event.preventDefault()
const win = new BrowserWindow({
webContents: options.webContents, // use existing webContents if provided
show: false
})
win.once('ready-to-show', () => win.show())
if (!options.webContents) {
const loadOptions = {
httpReferrer: referrer
}
if (postBody != null) {
const { data, contentType, boundary } = postBody
loadOptions.postData = postBody.data
loadOptions.extraHeaders = `content-type: ${contentType}; boundary=${boundary}`
}
win.loadURL(url, loadOptions) // existing webContents will be navigated automatically
}
event.newGuest = win
})
```
#### Event: 'did-create-window'
Returns:
* `window` BrowserWindow
* `details` Object
* `url` string - URL for the created window.
* `frameName` string - Name given to the created window in the
`window.open()` call.
* `options` BrowserWindowConstructorOptions - The options used to create the
BrowserWindow. They are merged in increasing precedence: parsed options
from the `features` string from `window.open()`, security-related
webPreferences inherited from the parent, and options given by
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
Unrecognized options are not filtered out.
* `referrer` [Referrer](structures/referrer.md) - The referrer that will be
passed to the new window. May or may not result in the `Referer` header
being sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data
that will be sent to the new window, along with the appropriate headers
that will be set. If no post data is to be sent, the value will be `null`.
Only defined when the window is being created by a form that set
`target=_blank`.
* `disposition` string - Can be `default`, `foreground-tab`,
`background-tab`, `new-window`, `save-to-disk` and `other`.
Emitted _after_ successful creation of a window via `window.open` in the renderer.
Not emitted if the creation of the window is canceled from
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
See [`window.open()`](window-open.md) for more details and how to use this in conjunction with `webContents.setWindowOpenHandler`.
#### Event: 'will-navigate'
Returns:
* `event` Event
* `url` string
Emitted when a user or the page wants to start navigation. It can happen when
the `window.location` object is changed or a user clicks a link in the page.
This event will not emit when the navigation is started programmatically with
APIs like `webContents.loadURL` and `webContents.back`.
It is also not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` will prevent the navigation.
#### Event: 'did-start-navigation'
Returns:
* `event` Event
* `url` string
* `isInPlace` boolean
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when any frame (including main) starts navigating. `isInPlace` will be
`true` for in-page navigations.
#### Event: 'will-redirect'
Returns:
* `event` Event
* `url` string
* `isInPlace` boolean
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when a server side redirect occurs during navigation. For example a 302
redirect.
This event will be emitted after `did-start-navigation` and always before the
`did-redirect-navigation` event for the same navigation.
Calling `event.preventDefault()` will prevent the navigation (not just the
redirect).
#### Event: 'did-redirect-navigation'
Returns:
* `event` Event
* `url` string
* `isInPlace` boolean
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted after a server side redirect occurs during navigation. For example a 302
redirect.
This event cannot be prevented, if you want to prevent redirects you should
checkout out the `will-redirect` event above.
#### Event: 'did-navigate'
Returns:
* `event` Event
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations
Emitted when a main frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
#### Event: 'did-frame-navigate'
Returns:
* `event` Event
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations,
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when any frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
#### Event: 'did-navigate-in-page'
Returns:
* `event` Event
* `url` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when an in-page navigation happened in any frame.
When in-page navigation happens, the page URL changes but does not cause
navigation outside of the page. Examples of this occurring are when anchor links
are clicked or when the DOM `hashchange` event is triggered.
#### Event: 'will-prevent-unload'
Returns:
* `event` Event
Emitted when a `beforeunload` event handler is attempting to cancel a page unload.
Calling `event.preventDefault()` will ignore the `beforeunload` event handler
and allow the page to be unloaded.
```javascript
const { BrowserWindow, dialog } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('will-prevent-unload', (event) => {
const choice = dialog.showMessageBoxSync(win, {
type: 'question',
buttons: ['Leave', 'Stay'],
title: 'Do you want to leave this site?',
message: 'Changes you made may not be saved.',
defaultId: 0,
cancelId: 1
})
const leave = (choice === 0)
if (leave) {
event.preventDefault()
}
})
```
**Note:** This will be emitted for `BrowserViews` but will _not_ be respected - this is because we have chosen not to tie the `BrowserView` lifecycle to its owning BrowserWindow should one exist per the [specification](https://developer.mozilla.org/en-US/docs/Web/API/Window/beforeunload_event).
#### Event: 'crashed' _Deprecated_
Returns:
* `event` Event
* `killed` boolean
Emitted when the renderer process crashes or is killed.
**Deprecated:** This event is superceded by the `render-process-gone` event
which contains more information about why the render process disappeared. It
isn't always because it crashed. The `killed` boolean can be replaced by
checking `reason === 'killed'` when you switch to that event.
#### Event: 'render-process-gone'
Returns:
* `event` Event
* `details` Object
* `reason` string - The reason the render process is gone. Possible values:
* `clean-exit` - Process exited with an exit code of zero
* `abnormal-exit` - Process exited with a non-zero exit code
* `killed` - Process was sent a SIGTERM or otherwise killed externally
* `crashed` - Process crashed
* `oom` - Process ran out of memory
* `launch-failed` - Process never successfully launched
* `integrity-failure` - Windows code integrity checks failed
* `exitCode` Integer - The exit code of the process, unless `reason` is
`launch-failed`, in which case `exitCode` will be a platform-specific
launch failure error code.
Emitted when the renderer process unexpectedly disappears. This is normally
because it was crashed or killed.
#### Event: 'unresponsive'
Emitted when the web page becomes unresponsive.
#### Event: 'responsive'
Emitted when the unresponsive web page becomes responsive again.
#### Event: 'plugin-crashed'
Returns:
* `event` Event
* `name` string
* `version` string
Emitted when a plugin process has crashed.
#### Event: 'destroyed'
Emitted when `webContents` is destroyed.
#### Event: 'before-input-event'
Returns:
* `event` Event
* `input` Object - Input properties.
* `type` string - Either `keyUp` or `keyDown`.
* `key` string - Equivalent to [KeyboardEvent.key][keyboardevent].
* `code` string - Equivalent to [KeyboardEvent.code][keyboardevent].
* `isAutoRepeat` boolean - Equivalent to [KeyboardEvent.repeat][keyboardevent].
* `isComposing` boolean - Equivalent to [KeyboardEvent.isComposing][keyboardevent].
* `shift` boolean - Equivalent to [KeyboardEvent.shiftKey][keyboardevent].
* `control` boolean - Equivalent to [KeyboardEvent.controlKey][keyboardevent].
* `alt` boolean - Equivalent to [KeyboardEvent.altKey][keyboardevent].
* `meta` boolean - Equivalent to [KeyboardEvent.metaKey][keyboardevent].
* `location` number - Equivalent to [KeyboardEvent.location][keyboardevent].
* `modifiers` string[] - See [InputEvent.modifiers](structures/input-event.md).
Emitted before dispatching the `keydown` and `keyup` events in the page.
Calling `event.preventDefault` will prevent the page `keydown`/`keyup` events
and the menu shortcuts.
To only prevent the menu shortcuts, use
[`setIgnoreMenuShortcuts`](#contentssetignoremenushortcutsignore):
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('before-input-event', (event, input) => {

Loads the `url` in the window. The `url` must contain the protocol prefix,
e.g. the `http://` or `file://`. If the load should bypass http cache then
use the `pragma` header to achieve it.
```javascript

```
Would require code like this
```js
win.loadFile('src/index.html')
```

Forcefully terminates the renderer process that is currently hosting this
`webContents`. This will cause the `render-process-gone` event to be emitted
with the `reason=killed || reason=crashed`. Please note that some webContents share renderer
processes and therefore calling this method may also crash the host process
for other webContents as well.
Calling `reload()` immediately after calling this
method will force the reload to occur in a new process. This should be used
when this process is unstable or unusable, for instance in order to recover
from the `unresponsive` event.
```js
contents.on('unresponsive', async () => {
const { response } = await dialog.showMessageBox({
message: 'App X has become unresponsive',
title: 'Do you want to try forcefully reloading the app?',
buttons: ['OK', 'Cancel'],

})
```
#### `contents.removeInsertedCSS(key)`
* `key` string
Returns `Promise<void>` - Resolves if the removal was successful.

contents.removeInsertedCSS(key)
})
```
#### `contents.executeJavaScript(code[, userGesture])`

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.
Code execution will be suspended until web page stop loading.
```js
contents.executeJavaScript('fetch("https://jsonplaceholder.typicode.com/users/1").then(resp => resp.json())', true)

* `scripts` [WebSource[]](structures/web-source.md)
* `userGesture` boolean (optional) - Default is `false`.
Returns `Promise<any>` - A promise that resolves with the result of the executed code
or is rejected if the result of the code is a rejected promise.
Works like `executeJavaScript` but evaluates `scripts` in an isolated context.
#### `contents.setIgnoreMenuShortcuts(ignore)`
* `ignore` boolean

sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data that
will be sent to the new window, along with the appropriate headers that will
be set. If no post data is to be sent, the value will be `null`. Only defined
when the window is being created by a form that set `target=_blank`.
Returns `{action: 'deny'} | {action: 'allow', overrideBrowserWindowOptions?: BrowserWindowConstructorOptions}` - `deny` cancels the creation of the new
window. `allow` will allow the new window to be created. Specifying `overrideBrowserWindowOptions` allows customization of the created window.
Returning an unrecognized value such as a null, undefined, or an object
without a recognized 'action' value will result in a console error and have
the same effect as returning `{action: 'deny'}`.
Called before creating a window a new window is requested by the renderer, e.g.
by `window.open()`, a link with `target="_blank"`, shift+clicking on a link, or
submitting a form with `<form target="_blank">`. See
[`window.open()`](window-open.md) for more details and how to use this in
conjunction with `did-create-window`.

limits of 300% and 50% of original size, respectively. The formula for this is
`scale := 1.2 ^ level`.
> **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.
#### `contents.getZoomLevel()`
Returns `number` - the current zoom level.
#### `contents.setVisualZoomLevelLimits(minimumLevel, maximumLevel)`
* `minimumLevel` number
* `maximumLevel` number
Returns `Promise<void>`

is large then 0.
#### `contents.incrementCapturerCount([size, stayHidden, stayAwake])`
* `size` [Size](structures/size.md) (optional) - The preferred size for the capturer.
* `stayHidden` boolean (optional) - Keep the page hidden instead of visible.
* `stayAwake` boolean (optional) - Keep the system awake instead of allowing it to sleep.
Increase the capturer count by one. The page is considered visible when its browser window is
hidden and the capturer count is non-zero. If you would like the page to stay hidden, you should ensure that `stayHidden` is set to true.
This also affects the Page Visibility API.
#### `contents.decrementCapturerCount([stayHidden, stayAwake])`
* `stayHidden` boolean (optional) - Keep the page in hidden state instead of visible.
* `stayAwake` boolean (optional) - Keep the system awake instead of allowing it to sleep.
Decrease the capturer count by one. The page will be set to hidden or occluded state when its
browser window is hidden or occluded and the capturer count reaches zero. If you want to
decrease the hidden capturer count instead you should set `stayHidden` to true.
#### `contents.getPrinters()` _Deprecated_
Get the system printer list.
Returns [`PrinterInfo[]`](structures/printer-info.md)
**Deprecated:** Should use the new [`contents.getPrintersAsync`](web-contents.md#contentsgetprintersasync) API.
#### `contents.getPrintersAsync()`
Get the system printer list.
Returns `Promise<PrinterInfo[]>` - Resolves with a [`PrinterInfo[]`](structures/printer-info.md)
#### `contents.print([options], [callback])`
* `options` Object (optional)
* `silent` boolean (optional) - Don't ask user for print settings. Default is `false`.
* `printBackground` boolean (optional) - Prints the background color and image of
the web page. Default is `false`.

* `failureReason` string - Error description called back if the print fails.
When a custom `pageSize` is passed, Chromium attempts to validate platform specific minimum values for `width_microns` and `height_microns`. Width and height must both be minimum 353 microns but may be higher on some operating systems.
Prints window's web page. When `silent` is set to `true`, Electron will pick
the system's default printer if `deviceName` is empty and the default settings for printing.
Use `page-break-before: always;` CSS style to force to print to a new page.
Example usage:
```js
const options = {
silent: true,
deviceName: 'My-Printer',
pageRanges: [{
from: 0,
to: 1
}]
}
win.webContents.print(options, (success, errorType) => {
if (!success) console.log(errorType)
})
```

* `printBackground` boolean (optional) - Whether to print CSS backgrounds.
* `printSelectionOnly` boolean (optional) - Whether to print selection only.
Returns `Promise<Buffer>` - Resolves with the generated PDF data.
Prints window's web page as PDF with Chromium's preview printing custom
settings.
The `landscape` will be ignored if `@page` CSS at-rule is used in the web page.
By default, an empty `options` will be regarded as:
```javascript
{
marginsType: 0,
printBackground: false,
printSelectionOnly: false,
landscape: false,
pageSize: 'A4',
scaleFactor: 100
}
```
Use `page-break-before: always;` CSS style to force to print to a new page.
An example of `webContents.printToPDF`:
```javascript
const { BrowserWindow } = require('electron')
const fs = require('fs')
const path = require('path')
const os = require('os')
const win = new BrowserWindow({ width: 800, height: 600 })
win.loadURL('http://github.com')
win.webContents.on('did-finish-load', () => {
// Use default printing options
const pdfPath = path.join(os.homedir(), 'Desktop', 'temp.pdf')
win.webContents.printToPDF({}).then(data => {
fs.writeFile(pdfPath, data, (error) => {
if (error) throw error
console.log(`Wrote PDF successfully to ${pdfPath}`)
})
}).catch(error => {
console.log(`Failed to write PDF to ${pdfPath}: `, error)
})
})
```
#### `contents.addWorkSpace(path)`
* `path` string
Adds the specified path to DevTools workspace. Must be used after DevTools
creation:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.webContents.on('devtools-opened', () => {
win.webContents.addWorkSpace(__dirname)
})
```
#### `contents.removeWorkSpace(path)`
* `path` string
Removes the specified path from DevTools workspace.
#### `contents.setDevToolsWebContents(devToolsWebContents)`
* `devToolsWebContents` WebContents
Uses the `devToolsWebContents` as the target `WebContents` to show devtools.
The `devToolsWebContents` must not have done any navigation, and it should not
be used for other purposes after the call.
By default Electron manages the devtools by creating an internal `WebContents`
with native view, which developers have very limited control of. With the
`setDevToolsWebContents` method, developers can use any `WebContents` to show
the devtools in it, including `BrowserWindow`, `BrowserView` and `<webview>`
tag.
Note that closing the devtools does not destroy the `devToolsWebContents`, it
is caller's responsibility to destroy `devToolsWebContents`.
An example of showing devtools in a `<webview>` tag:
```html
<html>
<head>
<style type="text/css">
* { margin: 0; }
#browser { height: 70%; }
#devtools { height: 30%; }
</style>
</head>
<body>
<webview id="browser" src="https://github.com"></webview>
<webview id="devtools" src="about:blank"></webview>
<script>
const { ipcRenderer } = require('electron')
const emittedOnce = (element, eventName) => new Promise(resolve => {
element.addEventListener(eventName, event => resolve(event), { once: true })
})
const browserView = document.getElementById('browser')
const devtoolsView = document.getElementById('devtools')
const browserReady = emittedOnce(browserView, 'dom-ready')
const devtoolsReady = emittedOnce(devtoolsView, 'dom-ready')
Promise.all([browserReady, devtoolsReady]).then(() => {
const targetId = browserView.getWebContentsId()
const devtoolsId = devtoolsView.getWebContentsId()
ipcRenderer.send('open-devtools', targetId, devtoolsId)
})
</script>
</body>
</html>
```
```js
// Main process
const { ipcMain, webContents } = require('electron')
ipcMain.on('open-devtools', (event, targetContentsId, devtoolsContentsId) => {
const target = webContents.fromId(targetContentsId)
const devtools = webContents.fromId(devtoolsContentsId)
target.setDevToolsWebContents(devtools)
target.openDevTools()
})
```
An example of showing devtools in a `BrowserWindow`:
```js
const { app, BrowserWindow } = require('electron')
let win = null
let devtools = null
app.whenReady().then(() => {
win = new BrowserWindow()
devtools = new BrowserWindow()
win.loadURL('https://github.com')
win.webContents.setDevToolsWebContents(devtools.webContents)
win.webContents.openDevTools({ mode: 'detach' })
})
```
#### `contents.openDevTools([options])`
* `options` Object (optional)
* `mode` string - Opens the devtools with specified dock state, can be
`left`, `right`, `bottom`, `undocked`, `detach`. Defaults to last used dock state.
In `undocked` mode it's possible to dock back. In `detach` mode it's not.
* `activate` boolean (optional) - Whether to bring the opened devtools window
to the foreground. The default is `true`.
Opens the devtools.
When `contents` is a `<webview>` tag, the `mode` would be `detach` by default,
explicitly passing an empty `mode` can force using last used dock state.
#### `contents.closeDevTools()`
Closes the devtools.
#### `contents.isDevToolsOpened()`
Returns `boolean` - Whether the devtools is opened.
#### `contents.isDevToolsFocused()`
Returns `boolean` - Whether the devtools view is focused .
#### `contents.toggleDevTools()`
Toggles the developer tools.
#### `contents.inspectElement(x, y)`
* `x` Integer
* `y` Integer
Starts inspecting element at position (`x`, `y`).
#### `contents.inspectSharedWorker()`
Opens the developer tools for the shared worker context.
#### `contents.inspectSharedWorkerById(workerId)`
* `workerId` string
Inspects the shared worker based on its ID.
#### `contents.getAllSharedWorkers()`
Returns [`SharedWorkerInfo[]`](structures/shared-worker-info.md) - Information about all Shared Workers.
#### `contents.inspectServiceWorker()`
Opens the developer tools for the service worker context.
#### `contents.send(channel, ...args)`
* `channel` string
* `...args` any[]
Send an asynchronous message to the renderer process via `channel`, along with
arguments. Arguments will be serialized with the [Structured Clone
Algorithm][SCA], just like [`postMessage`][], so prototype chains will not be
included. Sending Functions, Promises, Symbols, WeakMaps, or WeakSets will
throw an exception.
> **NOTE**: Sending non-standard JavaScript types such as DOM objects or
> special Electron objects will throw an exception.
The renderer process can handle the message by listening to `channel` with the
[`ipcRenderer`](ipc-renderer.md) module.
An example of sending messages from the main process to the renderer process:
```javascript
// In the main process.
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow({ width: 800, height: 600 })
win.loadURL(`file://${__dirname}/index.html`)
win.webContents.on('did-finish-load', () => {
win.webContents.send('ping', 'whoooooooh!')
})
})
```
```html
<!-- index.html -->
<html>
<body>
<script>
require('electron').ipcRenderer.on('ping', (event, message) => {
console.log(message) // Prints 'whoooooooh!'
})
</script>
</body>
</html>
```
#### `contents.sendToFrame(frameId, channel, ...args)`
* `frameId` Integer | [number, number] - the ID of the frame to send to, or a
pair of `[processId, frameId]` if the frame is in a different process to the
main frame.
* `channel` string
* `...args` any[]
Send an asynchronous message to a specific frame in a renderer process via
`channel`, along with arguments. Arguments will be serialized with the
[Structured Clone Algorithm][SCA], just like [`postMessage`][], so prototype
chains will not be included. Sending Functions, Promises, Symbols, WeakMaps, or
WeakSets will throw an exception.
> **NOTE:** Sending non-standard JavaScript types such as DOM objects or
> special Electron objects will throw an exception.
The renderer process can handle the message by listening to `channel` with the
[`ipcRenderer`](ipc-renderer.md) module.
If you want to get the `frameId` of a given renderer context you should use
the `webFrame.routingId` value. E.g.
```js
// In a renderer process
console.log('My frameId is:', require('electron').webFrame.routingId)
```
You can also read `frameId` from all incoming IPC messages in the main process.
```js
// In the main process
ipcMain.on('ping', (event) => {
console.info('Message came from frameId:', event.frameId)
})
```
#### `contents.postMessage(channel, message, [transfer])`
* `channel` string
* `message` any
* `transfer` MessagePortMain[] (optional)
Send a message to the renderer process, optionally transferring ownership of
zero or more [`MessagePortMain`][] objects.
The transferred `MessagePortMain` objects will be available in the renderer
process by accessing the `ports` property of the emitted event. When they
arrive in the renderer, they will be native DOM `MessagePort` objects.
For example:
```js
// Main process
const { port1, port2 } = new MessageChannelMain()
webContents.postMessage('port', { message: 'hello' }, [port1])
// Renderer process
ipcRenderer.on('port', (e, msg) => {
const [port] = e.ports
// ...
})
```
#### `contents.enableDeviceEmulation(parameters)`
* `parameters` Object
* `screenPosition` string - Specify the screen type to emulate
(default: `desktop`):
* `desktop` - Desktop screen type.
* `mobile` - Mobile screen type.
* `screenSize` [Size](structures/size.md) - Set the emulated screen size (screenPosition == mobile).
* `viewPosition` [Point](structures/point.md) - Position the view on the screen
(screenPosition == mobile) (default: `{ x: 0, y: 0 }`).
* `deviceScaleFactor` Integer - Set the device scale factor (if zero defaults to
original device scale factor) (default: `0`).
* `viewSize` [Size](structures/size.md) - Set the emulated view size (empty means no override)
* `scale` Float - Scale of emulated view inside available space (not in fit to
view mode) (default: `1`).
Enable device emulation with the given parameters.
#### `contents.disableDeviceEmulation()`
Disable device emulation enabled by `webContents.enableDeviceEmulation`.
#### `contents.sendInputEvent(inputEvent)`
* `inputEvent` [MouseInputEvent](structures/mouse-input-event.md) | [MouseWheelInputEvent](structures/mouse-wheel-input-event.md) | [KeyboardInputEvent](structures/keyboard-input-event.md)
Sends an input `event` to the page.
**Note:** The [`BrowserWindow`](browser-window.md) containing the contents needs to be focused for
`sendInputEvent()` to work.
#### `contents.beginFrameSubscription([onlyDirty ,]callback)`
* `onlyDirty` boolean (optional) - Defaults to `false`.
* `callback` Function
* `image` [NativeImage](native-image.md)
* `dirtyRect` [Rectangle](structures/rectangle.md)
Begin subscribing for presentation events and captured frames, the `callback`
will be called with `callback(image, dirtyRect)` when there is a presentation
event.
The `image` is an instance of [NativeImage](native-image.md) that stores the
captured frame.
The `dirtyRect` is an object with `x, y, width, height` properties that
describes which part of the page was repainted. If `onlyDirty` is set to
`true`, `image` will only contain the repainted area. `onlyDirty` defaults to
`false`.
#### `contents.endFrameSubscription()`
End subscribing for frame presentation events.
#### `contents.startDrag(item)`
* `item` Object
* `file` string - The path to the file being dragged.
* `files` string[] (optional) - The paths to the files being dragged. (`files` will override `file` field)
* `icon` [NativeImage](native-image.md) | string - The image must be
non-empty on macOS.
Sets the `item` as dragging item for current drag-drop operation, `file` is the
absolute path of the file to be dragged, and `icon` is the image showing under
the cursor when dragging.
#### `contents.savePage(fullPath, saveType)`
* `fullPath` string - The full file path.
* `saveType` string - Specify the save type.
* `HTMLOnly` - Save only the HTML of the page.

win.loadURL('https://github.com')
win.webContents.on('did-finish-load', async () => {
win.webContents.savePage('/tmp/test.html', 'HTMLComplete').then(() => {
console.log('Page was saved successfully.')

#### `contents.showDefinitionForSelection()` _macOS_
Shows pop-up dictionary that searches the selected word on the page.
#### `contents.isOffscreen()`
Returns `boolean` - Indicates whether *offscreen rendering* is enabled.
#### `contents.startPainting()`
If *offscreen rendering* is enabled and not painting, start painting.
#### `contents.stopPainting()`
If *offscreen rendering* is enabled and painting, stop painting.
#### `contents.isPainting()`
Returns `boolean` - If *offscreen rendering* is enabled returns whether it is currently painting.
#### `contents.setFrameRate(fps)`
* `fps` Integer
If *offscreen rendering* is enabled sets the frame rate to the specified number.
Only values between 1 and 240 are accepted.
#### `contents.getFrameRate()`
Returns `Integer` - If *offscreen rendering* is enabled returns the current frame rate.
#### `contents.invalidate()`
Schedules a full repaint of the window this web contents is in.
If *offscreen rendering* is enabled invalidates the frame and generates a new
one through the `'paint'` event.
#### `contents.getWebRTCIPHandlingPolicy()`
Returns `string` - Returns the WebRTC IP Handling Policy.
#### `contents.setWebRTCIPHandlingPolicy(policy)`
* `policy` string - Specify the WebRTC IP Handling Policy.
* `default` - Exposes user's public and local IPs. This is the default
behavior. When this policy is used, WebRTC has the right to enumerate all
interfaces and bind them to discover public interfaces.
* `default_public_interface_only` - Exposes user's public IP, but does not
expose user's local IP. When this policy is used, WebRTC should only use the
default route used by http. This doesn't expose any local addresses.
* `default_public_and_private_interfaces` - Exposes user's public and local
IPs. When this policy is used, WebRTC should only use the default route used
by http. This also exposes the associated default private address. Default
route is the route chosen by the OS on a multi-homed endpoint.
* `disable_non_proxied_udp` - Does not expose public or local IPs. When this
policy is used, WebRTC should only use TCP to contact peers or servers unless
the proxy server supports UDP.
Setting the WebRTC IP handling policy allows you to control which IPs are
exposed via WebRTC. See [BrowserLeaks](https://browserleaks.com/webrtc) for
more details.
#### `contents.getMediaSourceId(requestWebContents)`
* `requestWebContents` WebContents - Web contents that the id will be registered to.
Returns `string` - The identifier of a WebContents stream. This identifier can be used
with `navigator.mediaDevices.getUserMedia` using a `chromeMediaSource` of `tab`.
The identifier is restricted to the web contents that it is registered to and is only valid for 10 seconds.
#### `contents.getOSProcessId()`
Returns `Integer` - The operating system `pid` of the associated renderer
process.
#### `contents.getProcessId()`
Returns `Integer` - The Chromium internal `pid` of the associated renderer. Can
be compared to the `frameProcessId` passed by frame specific navigation events
(e.g. `did-frame-navigate`)
#### `contents.takeHeapSnapshot(filePath)`
* `filePath` string - Path to the output file.
Returns `Promise<void>` - Indicates whether the snapshot has been created successfully.
Takes a V8 heap snapshot and saves it to `filePath`.
#### `contents.getBackgroundThrottling()`
Returns `boolean` - whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.setBackgroundThrottling(allowed)`
* `allowed` boolean
Controls whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.getType()`
Returns `string` - the type of the webContent. Can be `backgroundPage`, `window`, `browserView`, `remote`, `webview` or `offscreen`.
#### `contents.setImageAnimationPolicy(policy)`
* `policy` string - Can be `animate`, `animateOnce` or `noAnimation`.
Sets the image animation policy for this webContents. The policy only affects
_new_ images, existing images that are currently being animated are unaffected.
This is a known limitation in Chromium, you can force image animation to be
recalculated with `img.src = img.src` which will result in no network traffic
but will update the animation policy.
This corresponds to the [animationPolicy][] accessibility feature in Chromium.
[animationPolicy]: https://developer.chrome.com/docs/extensions/reference/accessibilityFeatures/#property-animationPolicy
### Instance Properties
#### `contents.audioMuted`
A `boolean` property that determines whether this page is muted.
#### `contents.userAgent`
A `string` property that determines the user agent for this web page.
#### `contents.zoomLevel`
A `number` property that determines the zoom level for this web contents.
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. The formula for this is `scale := 1.2 ^ level`.
#### `contents.zoomFactor`
A `number` property that determines the zoom factor for this web contents.
The zoom factor is the zoom percent divided by 100, so 300% = 3.0.
#### `contents.frameRate`
An `Integer` property that sets the frame rate of the web contents to the specified number.
Only values between 1 and 240 are accepted.
Only applicable if *offscreen rendering* is enabled.

#### `contents.devToolsWebContents` _Readonly_
A `WebContents | null` property that represents the of DevTools `WebContents` associated with a given `WebContents`.
**Note:** Users should never store this object because it may become `null`
when the DevTools has been closed.
#### `contents.debugger` _Readonly_
A [`Debugger`](debugger.md) instance for this webContents.
#### `contents.backgroundThrottling`
A `boolean` property that determines whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.mainFrame` _Readonly_

[Bug]: savePage no generated files
|
### 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
16.0.0
### What operating system are you using?
Windows
### Operating System Version
WIN10 20H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
win.webContents.savePage('d:/aaaaaa.html', 'HTMLComplete').then(() => {
console.log('Page was saved successfully.')
}).catch(err => {
console.log(err)
})
it will generate a html page file at d:
### Actual Behavior
savePage has three formats that can be used
if use HTMLComplete
only produced a aaaaaa_files empty folder
if use HTMLonly
No files are generated nor error callbacks are generated
MHTML option works fine
### Testcase Gist URL
_No response_
### Additional Information
_No response_

# webContents
> Render and control web pages.
Process: [Main](../glossary.md#main-process)
`webContents` is an [EventEmitter][event-emitter].
It is responsible for rendering and controlling a web page and is a property of
the [`BrowserWindow`](browser-window.md) object. An example of accessing the
`webContents` object:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 1500 })
win.loadURL('http://github.com')
const contents = win.webContents
console.log(contents)
```
## Methods
These methods can be accessed from the `webContents` module:
```javascript
const { webContents } = require('electron')
console.log(webContents)
```
### `webContents.getAllWebContents()`
Returns `WebContents[]` - An array of all `WebContents` instances. This will contain web contents
for all windows, webviews, opened devtools, and devtools extension background pages.
### `webContents.getFocusedWebContents()`
Returns `WebContents` - The web contents that is focused in this application, otherwise
returns `null`.
### `webContents.fromId(id)`
* `id` Integer
Returns `WebContents` | undefined - A WebContents instance with the given ID, or
`undefined` if there is no WebContents associated with the given ID.
### `webContents.fromDevToolsTargetId(targetId)`
* `targetId` string - The Chrome DevTools Protocol [TargetID](https://chromedevtools.github.io/devtools-protocol/tot/Target/#type-TargetID) associated with the WebContents instance.
Returns `WebContents` | undefined - A WebContents instance with the given TargetID, or
`undefined` if there is no WebContents associated with the given TargetID.
When communicating with the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/),
it can be useful to lookup a WebContents instance based on its assigned TargetID.
```js
async function lookupTargetId (browserWindow) {
const wc = browserWindow.webContents
await wc.debugger.attach('1.3')
const { targetInfo } = await wc.debugger.sendCommand('Target.getTargetInfo')
const { targetId } = targetInfo
const targetWebContents = await webContents.fromDevToolsTargetId(targetId)
}
```
## Class: WebContents
> Render and control the contents of a BrowserWindow instance.
Process: [Main](../glossary.md#main-process)<br />
_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
### Instance Events
#### Event: 'did-finish-load'
Emitted when the navigation is done, i.e. the spinner of the tab has stopped
spinning, and the `onload` event was dispatched.
#### Event: 'did-fail-load'
Returns:
* `event` Event
* `errorCode` Integer
* `errorDescription` string
* `validatedURL` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
This event is like `did-finish-load` but emitted when the load failed.
The full list of error codes and their meaning is available [here](https://source.chromium.org/chromium/chromium/src/+/master:net/base/net_error_list.h).
#### Event: 'did-fail-provisional-load'
Returns:
* `event` Event
* `errorCode` Integer
* `errorDescription` string
* `validatedURL` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
This event is like `did-fail-load` but emitted when the load was cancelled
(e.g. `window.stop()` was invoked).
#### Event: 'did-frame-finish-load'
Returns:
* `event` Event
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when a frame has done navigation.
#### Event: 'did-start-loading'
Corresponds to the points in time when the spinner of the tab started spinning.
#### Event: 'did-stop-loading'
Corresponds to the points in time when the spinner of the tab stopped spinning.
#### Event: 'dom-ready'
Returns:
* `event` Event
Emitted when the document in the top-level frame is loaded.
#### Event: 'page-title-updated'
Returns:
* `event` Event
* `title` string
* `explicitSet` boolean
Fired when page title is set during navigation. `explicitSet` is false when
title is synthesized from file url.
#### Event: 'page-favicon-updated'
Returns:
* `event` Event
* `favicons` string[] - Array of URLs.
Emitted when page receives favicon urls.
#### Event: 'new-window' _Deprecated_
Returns:
* `event` NewWindowWebContentsEvent
* `url` string
* `frameName` string
* `disposition` string - Can be `default`, `foreground-tab`, `background-tab`,
`new-window`, `save-to-disk` and `other`.
* `options` BrowserWindowConstructorOptions - The options which will be used for creating the new
[`BrowserWindow`](browser-window.md).
* `additionalFeatures` string[] - The non-standard features (features not handled
by Chromium or Electron) given to `window.open()`. Deprecated, and will now
always be the empty array `[]`.
* `referrer` [Referrer](structures/referrer.md) - The referrer that will be
passed to the new window. May or may not result in the `Referer` header being
sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data that
will be sent to the new window, along with the appropriate headers that will
be set. If no post data is to be sent, the value will be `null`. Only defined
when the window is being created by a form that set `target=_blank`.
Deprecated in favor of [`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
Emitted when the page requests to open a new window for a `url`. It could be
requested by `window.open` or an external link like `<a target='_blank'>`.
By default a new `BrowserWindow` will be created for the `url`.
Calling `event.preventDefault()` will prevent Electron from automatically creating a
new [`BrowserWindow`](browser-window.md). If you call `event.preventDefault()` and manually create a new
[`BrowserWindow`](browser-window.md) then you must set `event.newGuest` to reference the new [`BrowserWindow`](browser-window.md)
instance, failing to do so may result in unexpected behavior. For example:
```javascript
myBrowserWindow.webContents.on('new-window', (event, url, frameName, disposition, options, additionalFeatures, referrer, postBody) => {
event.preventDefault()
const win = new BrowserWindow({
webContents: options.webContents, // use existing webContents if provided
show: false
})
win.once('ready-to-show', () => win.show())
if (!options.webContents) {
const loadOptions = {
httpReferrer: referrer
}
if (postBody != null) {
const { data, contentType, boundary } = postBody
loadOptions.postData = postBody.data
loadOptions.extraHeaders = `content-type: ${contentType}; boundary=${boundary}`
}
win.loadURL(url, loadOptions) // existing webContents will be navigated automatically
}
event.newGuest = win
})
```
#### Event: 'did-create-window'
Returns:
* `window` BrowserWindow
* `details` Object
* `url` string - URL for the created window.
* `frameName` string - Name given to the created window in the
`window.open()` call.
* `options` BrowserWindowConstructorOptions - The options used to create the
BrowserWindow. They are merged in increasing precedence: parsed options
from the `features` string from `window.open()`, security-related
webPreferences inherited from the parent, and options given by
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
Unrecognized options are not filtered out.
* `referrer` [Referrer](structures/referrer.md) - The referrer that will be
passed to the new window. May or may not result in the `Referer` header
being sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data
that will be sent to the new window, along with the appropriate headers
that will be set. If no post data is to be sent, the value will be `null`.
Only defined when the window is being created by a form that set
`target=_blank`.
* `disposition` string - Can be `default`, `foreground-tab`,
`background-tab`, `new-window`, `save-to-disk` and `other`.
Emitted _after_ successful creation of a window via `window.open` in the renderer.
Not emitted if the creation of the window is canceled from
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
See [`window.open()`](window-open.md) for more details and how to use this in conjunction with `webContents.setWindowOpenHandler`.
#### Event: 'will-navigate'
Returns:
* `event` Event
* `url` string
Emitted when a user or the page wants to start navigation. It can happen when
the `window.location` object is changed or a user clicks a link in the page.
This event will not emit when the navigation is started programmatically with
APIs like `webContents.loadURL` and `webContents.back`.
It is also not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` will prevent the navigation.
#### Event: 'did-start-navigation'
Returns:
* `event` Event
* `url` string
* `isInPlace` boolean
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when any frame (including main) starts navigating. `isInPlace` will be
`true` for in-page navigations.
#### Event: 'will-redirect'
Returns:
* `event` Event
* `url` string
* `isInPlace` boolean
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when a server side redirect occurs during navigation. For example a 302
redirect.
This event will be emitted after `did-start-navigation` and always before the
`did-redirect-navigation` event for the same navigation.
Calling `event.preventDefault()` will prevent the navigation (not just the
redirect).
#### Event: 'did-redirect-navigation'
Returns:
* `event` Event
* `url` string
* `isInPlace` boolean
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted after a server side redirect occurs during navigation. For example a 302
redirect.
This event cannot be prevented, if you want to prevent redirects you should
checkout out the `will-redirect` event above.
#### Event: 'did-navigate'
Returns:
* `event` Event
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations
Emitted when a main frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
#### Event: 'did-frame-navigate'
Returns:
* `event` Event
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations,
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when any frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
#### Event: 'did-navigate-in-page'
Returns:
* `event` Event
* `url` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when an in-page navigation happened in any frame.
When in-page navigation happens, the page URL changes but does not cause
navigation outside of the page. Examples of this occurring are when anchor links
are clicked or when the DOM `hashchange` event is triggered.
#### Event: 'will-prevent-unload'
Returns:
* `event` Event
Emitted when a `beforeunload` event handler is attempting to cancel a page unload.
Calling `event.preventDefault()` will ignore the `beforeunload` event handler
and allow the page to be unloaded.
```javascript
const { BrowserWindow, dialog } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('will-prevent-unload', (event) => {
const choice = dialog.showMessageBoxSync(win, {
type: 'question',
buttons: ['Leave', 'Stay'],
title: 'Do you want to leave this site?',
message: 'Changes you made may not be saved.',
defaultId: 0,
cancelId: 1
})
const leave = (choice === 0)
if (leave) {
event.preventDefault()
}
})
```
**Note:** This will be emitted for `BrowserViews` but will _not_ be respected - this is because we have chosen not to tie the `BrowserView` lifecycle to its owning BrowserWindow should one exist per the [specification](https://developer.mozilla.org/en-US/docs/Web/API/Window/beforeunload_event).
#### Event: 'crashed' _Deprecated_
Returns:
* `event` Event
* `killed` boolean
Emitted when the renderer process crashes or is killed.
**Deprecated:** This event is superceded by the `render-process-gone` event
which contains more information about why the render process disappeared. It
isn't always because it crashed. The `killed` boolean can be replaced by
checking `reason === 'killed'` when you switch to that event.
#### Event: 'render-process-gone'
Returns:
* `event` Event
* `details` Object
* `reason` string - The reason the render process is gone. Possible values:
* `clean-exit` - Process exited with an exit code of zero
* `abnormal-exit` - Process exited with a non-zero exit code
* `killed` - Process was sent a SIGTERM or otherwise killed externally
* `crashed` - Process crashed
* `oom` - Process ran out of memory
* `launch-failed` - Process never successfully launched
* `integrity-failure` - Windows code integrity checks failed
* `exitCode` Integer - The exit code of the process, unless `reason` is
`launch-failed`, in which case `exitCode` will be a platform-specific
launch failure error code.
Emitted when the renderer process unexpectedly disappears. This is normally
because it was crashed or killed.
#### Event: 'unresponsive'
Emitted when the web page becomes unresponsive.
#### Event: 'responsive'
Emitted when the unresponsive web page becomes responsive again.
#### Event: 'plugin-crashed'
Returns:
* `event` Event
* `name` string
* `version` string
Emitted when a plugin process has crashed.
#### Event: 'destroyed'
Emitted when `webContents` is destroyed.
#### Event: 'before-input-event'
Returns:
* `event` Event
* `input` Object - Input properties.
* `type` string - Either `keyUp` or `keyDown`.
* `key` string - Equivalent to [KeyboardEvent.key][keyboardevent].
* `code` string - Equivalent to [KeyboardEvent.code][keyboardevent].
* `isAutoRepeat` boolean - Equivalent to [KeyboardEvent.repeat][keyboardevent].
* `isComposing` boolean - Equivalent to [KeyboardEvent.isComposing][keyboardevent].
* `shift` boolean - Equivalent to [KeyboardEvent.shiftKey][keyboardevent].
* `control` boolean - Equivalent to [KeyboardEvent.controlKey][keyboardevent].
* `alt` boolean - Equivalent to [KeyboardEvent.altKey][keyboardevent].
* `meta` boolean - Equivalent to [KeyboardEvent.metaKey][keyboardevent].
* `location` number - Equivalent to [KeyboardEvent.location][keyboardevent].
* `modifiers` string[] - See [InputEvent.modifiers](structures/input-event.md).
Emitted before dispatching the `keydown` and `keyup` events in the page.
Calling `event.preventDefault` will prevent the page `keydown`/`keyup` events
and the menu shortcuts.
To only prevent the menu shortcuts, use
[`setIgnoreMenuShortcuts`](#contentssetignoremenushortcutsignore):
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('before-input-event', (event, input) => {
// For example, only enable application menu keyboard shortcuts when
// Ctrl/Cmd are down.
win.webContents.setIgnoreMenuShortcuts(!input.control && !input.meta)
})
```
#### 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: 'zoom-changed'
Returns:
* `event` Event
* `zoomDirection` string - Can be `in` or `out`.
Emitted when the user is requesting to change the zoom level using the mouse wheel.
#### Event: 'blur'
Emitted when the `WebContents` loses focus.
#### Event: 'focus'
Emitted when the `WebContents` gains focus.
Note that on macOS, having focus means the `WebContents` is the first responder
of window, so switching focus between windows would not trigger the `focus` and
`blur` events of `WebContents`, as the first responder of each window is not
changed.
The `focus` and `blur` events of `WebContents` should only be used to detect
focus change between different `WebContents` and `BrowserView` in the same
window.
#### Event: 'devtools-opened'

`app`](app.md#event-certificate-error).
#### Event: 'select-client-certificate'
Returns:
* `event` Event
* `url` URL
* `certificateList` [Certificate[]](structures/certificate.md)
* `callback` Function

Loads the `url` in the window. The `url` must contain the protocol prefix,
e.g. the `http://` or `file://`. If the load should bypass http cache then
use the `pragma` header to achieve it.
```javascript

```
Would require code like this
```js
win.loadFile('src/index.html')
```

#### `contents.forcefullyCrashRenderer()`
Forcefully terminates the renderer process that is currently hosting this
`webContents`. This will cause the `render-process-gone` event to be emitted
with the `reason=killed || reason=crashed`. Please note that some webContents share renderer
processes and therefore calling this method may also crash the host process
for other webContents as well.
Calling `reload()` immediately after calling this
method will force the reload to occur in a new process. This should be used
when this process is unstable or unusable, for instance in order to recover
from the `unresponsive` event.
```js
contents.on('unresponsive', async () => {
const { response } = await dialog.showMessageBox({
message: 'App X has become unresponsive',
title: 'Do you want to try forcefully reloading the app?',
buttons: ['OK', 'Cancel'],

})
```
#### `contents.removeInsertedCSS(key)`
* `key` string
Returns `Promise<void>` - Resolves if the removal was successful.
Removes the inserted CSS from the current web page. The stylesheet is identified

const key = await contents.insertCSS('html, body { background-color: #f00; }')
contents.removeInsertedCSS(key)
})
```
#### `contents.executeJavaScript(code[, userGesture])`

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.
Code execution will be suspended until web page stop loading.
```js
contents.executeJavaScript('fetch("https://jsonplaceholder.typicode.com/users/1").then(resp => resp.json())', true)
.then((result) => {

* `scripts` [WebSource[]](structures/web-source.md)
* `userGesture` boolean (optional) - Default is `false`.
Returns `Promise<any>` - A promise that resolves with the result of the executed code
or is rejected if the result of the code is a rejected promise.
Works like `executeJavaScript` but evaluates `scripts` in an isolated context.
#### `contents.setIgnoreMenuShortcuts(ignore)`
* `ignore` boolean

sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data that
will be sent to the new window, along with the appropriate headers that will
be set. If no post data is to be sent, the value will be `null`. Only defined
when the window is being created by a form that set `target=_blank`.
Returns `{action: 'deny'} | {action: 'allow', overrideBrowserWindowOptions?: BrowserWindowConstructorOptions}` - `deny` cancels the creation of the new
window. `allow` will allow the new window to be created. Specifying `overrideBrowserWindowOptions` allows customization of the created window.
Returning an unrecognized value such as a null, undefined, or an object
without a recognized 'action' value will result in a console error and have
the same effect as returning `{action: 'deny'}`.
Called before creating a window a new window is requested by the renderer, e.g.
by `window.open()`, a link with `target="_blank"`, shift+clicking on a link, or
submitting a form with `<form target="_blank">`. See
[`window.open()`](window-open.md) for more details and how to use this in
conjunction with `did-create-window`.

increment above or below represents zooming 20% larger or smaller to default
limits of 300% and 50% of original size, respectively. The formula for this is
`scale := 1.2 ^ level`.
> **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.
#### `contents.getZoomLevel()`
Returns `number` - the current zoom level.
#### `contents.setVisualZoomLevelLimits(minimumLevel, maximumLevel)`
* `minimumLevel` number
* `maximumLevel` number
Returns `Promise<void>`

When a custom `pageSize` is passed, Chromium attempts to validate platform specific minimum values for `width_microns` and `height_microns`. Width and height must both be minimum 353 microns but may be higher on some operating systems.
Prints window's web page. When `silent` is set to `true`, Electron will pick
the system's default printer if `deviceName` is empty and the default settings for printing.
Use `page-break-before: always;` CSS style to force to print to a new page.
Example usage:
```js
const options = {
silent: true,
deviceName: 'My-Printer',
pageRanges: [{
from: 0,
to: 1
}]
}
win.webContents.print(options, (success, errorType) => {
if (!success) console.log(errorType)
})
```
#### `contents.printToPDF(options)`
* `options` Object
* `headerFooter` Record<string, string> (optional) - the header and footer for the PDF.
* `title` string - The title for the PDF header.
* `url` string - the url for the PDF footer.
* `landscape` boolean (optional) - `true` for landscape, `false` for portrait.
* `marginsType` Integer (optional) - Specifies the type of margins to use. Uses 0 for
default margin, 1 for no margin, and 2 for minimum margin.
* `scaleFactor` number (optional) - The scale factor of the web page. Can range from 0 to 100.
* `pageRanges` Record<string, number> (optional) - The page range to print.
* `from` number - Index of the first page to print (0-based).
* `to` number - Index of the last page to print (inclusive) (0-based).
* `pageSize` string | Size (optional) - Specify page size of the generated PDF. Can be `A3`,
`A4`, `A5`, `Legal`, `Letter`, `Tabloid` or an Object containing `height` and `width` in microns.
* `printBackground` boolean (optional) - Whether to print CSS backgrounds.
* `printSelectionOnly` boolean (optional) - Whether to print selection only.
Returns `Promise<Buffer>` - Resolves with the generated PDF data.
Prints window's web page as PDF with Chromium's preview printing custom
settings.
The `landscape` will be ignored if `@page` CSS at-rule is used in the web page.
By default, an empty `options` will be regarded as:
```javascript
{
marginsType: 0,
printBackground: false,
printSelectionOnly: false,
landscape: false,
pageSize: 'A4',
scaleFactor: 100
}
```
Use `page-break-before: always;` CSS style to force to print to a new page.
An example of `webContents.printToPDF`:
```javascript
const { BrowserWindow } = require('electron')
const fs = require('fs')
const path = require('path')
const os = require('os')
const win = new BrowserWindow({ width: 800, height: 600 })
win.loadURL('http://github.com')
win.webContents.on('did-finish-load', () => {
// Use default printing options
const pdfPath = path.join(os.homedir(), 'Desktop', 'temp.pdf')
win.webContents.printToPDF({}).then(data => {
fs.writeFile(pdfPath, data, (error) => {
if (error) throw error
console.log(`Wrote PDF successfully to ${pdfPath}`)
})
}).catch(error => {
console.log(`Failed to write PDF to ${pdfPath}: `, error)
})
})
```
#### `contents.addWorkSpace(path)`
* `path` string
Adds the specified path to DevTools workspace. Must be used after DevTools
creation:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.webContents.on('devtools-opened', () => {
win.webContents.addWorkSpace(__dirname)
})
```
#### `contents.removeWorkSpace(path)`
* `path` string
Removes the specified path from DevTools workspace.
#### `contents.setDevToolsWebContents(devToolsWebContents)`
* `devToolsWebContents` WebContents
Uses the `devToolsWebContents` as the target `WebContents` to show devtools.
The `devToolsWebContents` must not have done any navigation, and it should not
be used for other purposes after the call.
By default Electron manages the devtools by creating an internal `WebContents`
with native view, which developers have very limited control of. With the
`setDevToolsWebContents` method, developers can use any `WebContents` to show
the devtools in it, including `BrowserWindow`, `BrowserView` and `<webview>`
tag.
Note that closing the devtools does not destroy the `devToolsWebContents`, it
is caller's responsibility to destroy `devToolsWebContents`.
An example of showing devtools in a `<webview>` tag:
```html
<html>
<head>
<style type="text/css">
* { margin: 0; }
#browser { height: 70%; }
#devtools { height: 30%; }
</style>
</head>
<body>
<webview id="browser" src="https://github.com"></webview>
<webview id="devtools" src="about:blank"></webview>
<script>
const { ipcRenderer } = require('electron')
const emittedOnce = (element, eventName) => new Promise(resolve => {
element.addEventListener(eventName, event => resolve(event), { once: true })
})
const browserView = document.getElementById('browser')
const devtoolsView = document.getElementById('devtools')
const browserReady = emittedOnce(browserView, 'dom-ready')
const devtoolsReady = emittedOnce(devtoolsView, 'dom-ready')
Promise.all([browserReady, devtoolsReady]).then(() => {
const targetId = browserView.getWebContentsId()
const devtoolsId = devtoolsView.getWebContentsId()
ipcRenderer.send('open-devtools', targetId, devtoolsId)
})
</script>
</body>
</html>
```
```js
// Main process
const { ipcMain, webContents } = require('electron')
ipcMain.on('open-devtools', (event, targetContentsId, devtoolsContentsId) => {
const target = webContents.fromId(targetContentsId)
const devtools = webContents.fromId(devtoolsContentsId)
target.setDevToolsWebContents(devtools)
target.openDevTools()
})
```
An example of showing devtools in a `BrowserWindow`:
```js
const { app, BrowserWindow } = require('electron')
let win = null
let devtools = null
app.whenReady().then(() => {
win = new BrowserWindow()
devtools = new BrowserWindow()
win.loadURL('https://github.com')
win.webContents.setDevToolsWebContents(devtools.webContents)
win.webContents.openDevTools({ mode: 'detach' })
})
```
#### `contents.openDevTools([options])`
* `options` Object (optional)
* `mode` string - Opens the devtools with specified dock state, can be
`left`, `right`, `bottom`, `undocked`, `detach`. Defaults to last used dock state.
In `undocked` mode it's possible to dock back. In `detach` mode it's not.
* `activate` boolean (optional) - Whether to bring the opened devtools window
to the foreground. The default is `true`.
Opens the devtools.
When `contents` is a `<webview>` tag, the `mode` would be `detach` by default,
explicitly passing an empty `mode` can force using last used dock state.
#### `contents.closeDevTools()`
Closes the devtools.
#### `contents.isDevToolsOpened()`
Returns `boolean` - Whether the devtools is opened.
#### `contents.isDevToolsFocused()`
Returns `boolean` - Whether the devtools view is focused .
#### `contents.toggleDevTools()`
Toggles the developer tools.
#### `contents.inspectElement(x, y)`
* `x` Integer
* `y` Integer
Starts inspecting element at position (`x`, `y`).
#### `contents.inspectSharedWorker()`
Opens the developer tools for the shared worker context.
#### `contents.inspectSharedWorkerById(workerId)`
* `workerId` string
Inspects the shared worker based on its ID.
#### `contents.getAllSharedWorkers()`
Returns [`SharedWorkerInfo[]`](structures/shared-worker-info.md) - Information about all Shared Workers.
#### `contents.inspectServiceWorker()`
Opens the developer tools for the service worker context.
#### `contents.send(channel, ...args)`
* `channel` string
* `...args` any[]
Send an asynchronous message to the renderer process via `channel`, along with
arguments. Arguments will be serialized with the [Structured Clone
Algorithm][SCA], just like [`postMessage`][], so prototype chains will not be
included. Sending Functions, Promises, Symbols, WeakMaps, or WeakSets will
throw an exception.
> **NOTE**: Sending non-standard JavaScript types such as DOM objects or
> special Electron objects will throw an exception.
The renderer process can handle the message by listening to `channel` with the
[`ipcRenderer`](ipc-renderer.md) module.
An example of sending messages from the main process to the renderer process:
```javascript
// In the main process.
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow({ width: 800, height: 600 })
win.loadURL(`file://${__dirname}/index.html`)
win.webContents.on('did-finish-load', () => {
win.webContents.send('ping', 'whoooooooh!')
})
})
```
```html
<!-- index.html -->
<html>
<body>
<script>
require('electron').ipcRenderer.on('ping', (event, message) => {
console.log(message) // Prints 'whoooooooh!'
})
</script>
</body>
</html>
```
#### `contents.sendToFrame(frameId, channel, ...args)`
* `frameId` Integer | [number, number] - the ID of the frame to send to, or a
pair of `[processId, frameId]` if the frame is in a different process to the
main frame.
* `channel` string
* `...args` any[]
Send an asynchronous message to a specific frame in a renderer process via
`channel`, along with arguments. Arguments will be serialized with the
[Structured Clone Algorithm][SCA], just like [`postMessage`][], so prototype
chains will not be included. Sending Functions, Promises, Symbols, WeakMaps, or
WeakSets will throw an exception.
> **NOTE:** Sending non-standard JavaScript types such as DOM objects or
> special Electron objects will throw an exception.
The renderer process can handle the message by listening to `channel` with the
[`ipcRenderer`](ipc-renderer.md) module.
If you want to get the `frameId` of a given renderer context you should use
the `webFrame.routingId` value. E.g.
```js
// In a renderer process
console.log('My frameId is:', require('electron').webFrame.routingId)
```
You can also read `frameId` from all incoming IPC messages in the main process.
```js
// In the main process
ipcMain.on('ping', (event) => {
console.info('Message came from frameId:', event.frameId)
})
```
#### `contents.postMessage(channel, message, [transfer])`
* `channel` string
* `message` any
* `transfer` MessagePortMain[] (optional)
Send a message to the renderer process, optionally transferring ownership of
zero or more [`MessagePortMain`][] objects.
The transferred `MessagePortMain` objects will be available in the renderer
process by accessing the `ports` property of the emitted event. When they
arrive in the renderer, they will be native DOM `MessagePort` objects.
For example:
```js
// Main process
const { port1, port2 } = new MessageChannelMain()
webContents.postMessage('port', { message: 'hello' }, [port1])
// Renderer process
ipcRenderer.on('port', (e, msg) => {
const [port] = e.ports
// ...
})
```
#### `contents.enableDeviceEmulation(parameters)`
* `parameters` Object
* `screenPosition` string - Specify the screen type to emulate
(default: `desktop`):
* `desktop` - Desktop screen type.
* `mobile` - Mobile screen type.
* `screenSize` [Size](structures/size.md) - Set the emulated screen size (screenPosition == mobile).
* `viewPosition` [Point](structures/point.md) - Position the view on the screen
(screenPosition == mobile) (default: `{ x: 0, y: 0 }`).
* `deviceScaleFactor` Integer - Set the device scale factor (if zero defaults to
original device scale factor) (default: `0`).
* `viewSize` [Size](structures/size.md) - Set the emulated view size (empty means no override)
* `scale` Float - Scale of emulated view inside available space (not in fit to
view mode) (default: `1`).
Enable device emulation with the given parameters.
#### `contents.disableDeviceEmulation()`
Disable device emulation enabled by `webContents.enableDeviceEmulation`.
#### `contents.sendInputEvent(inputEvent)`
* `inputEvent` [MouseInputEvent](structures/mouse-input-event.md) | [MouseWheelInputEvent](structures/mouse-wheel-input-event.md) | [KeyboardInputEvent](structures/keyboard-input-event.md)
Sends an input `event` to the page.
**Note:** The [`BrowserWindow`](browser-window.md) containing the contents needs to be focused for
`sendInputEvent()` to work.
#### `contents.beginFrameSubscription([onlyDirty ,]callback)`
* `onlyDirty` boolean (optional) - Defaults to `false`.
* `callback` Function
* `image` [NativeImage](native-image.md)
* `dirtyRect` [Rectangle](structures/rectangle.md)
Begin subscribing for presentation events and captured frames, the `callback`
will be called with `callback(image, dirtyRect)` when there is a presentation
event.
The `image` is an instance of [NativeImage](native-image.md) that stores the
captured frame.
The `dirtyRect` is an object with `x, y, width, height` properties that
describes which part of the page was repainted. If `onlyDirty` is set to
`true`, `image` will only contain the repainted area. `onlyDirty` defaults to
`false`.
#### `contents.endFrameSubscription()`
End subscribing for frame presentation events.
#### `contents.startDrag(item)`
* `item` Object
* `file` string - The path to the file being dragged.
* `files` string[] (optional) - The paths to the files being dragged. (`files` will override `file` field)
* `icon` [NativeImage](native-image.md) | string - The image must be
non-empty on macOS.
Sets the `item` as dragging item for current drag-drop operation, `file` is the
absolute path of the file to be dragged, and `icon` is the image showing under
the cursor when dragging.
#### `contents.savePage(fullPath, saveType)`
* `fullPath` string - The full file path.
* `saveType` string - Specify the save type.
* `HTMLOnly` - Save only the HTML of the page.
* `HTMLComplete` - Save complete-html page.
* `MHTML` - Save complete-html page as MHTML.
Returns `Promise<void>` - resolves if the page is saved.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.loadURL('https://github.com')
win.webContents.on('did-finish-load', async () => {
win.webContents.savePage('/tmp/test.html', 'HTMLComplete').then(() => {
console.log('Page was saved successfully.')
}).catch(err => {
console.log(err)
})
})
```
#### `contents.showDefinitionForSelection()` _macOS_
Shows pop-up dictionary that searches the selected word on the page.
#### `contents.isOffscreen()`
Returns `boolean` - Indicates whether *offscreen rendering* is enabled.
#### `contents.startPainting()`
If *offscreen rendering* is enabled and not painting, start painting.
#### `contents.stopPainting()`
If *offscreen rendering* is enabled and painting, stop painting.
#### `contents.isPainting()`
Returns `boolean` - If *offscreen rendering* is enabled returns whether it is currently painting.
#### `contents.setFrameRate(fps)`
* `fps` Integer
If *offscreen rendering* is enabled sets the frame rate to the specified number.
Only values between 1 and 240 are accepted.
#### `contents.getFrameRate()`
Returns `Integer` - If *offscreen rendering* is enabled returns the current frame rate.
#### `contents.invalidate()`
Schedules a full repaint of the window this web contents is in.
If *offscreen rendering* is enabled invalidates the frame and generates a new
one through the `'paint'` event.
#### `contents.getWebRTCIPHandlingPolicy()`
Returns `string` - Returns the WebRTC IP Handling Policy.
#### `contents.setWebRTCIPHandlingPolicy(policy)`
* `policy` string - Specify the WebRTC IP Handling Policy.
* `default` - Exposes user's public and local IPs. This is the default
behavior. When this policy is used, WebRTC has the right to enumerate all
interfaces and bind them to discover public interfaces.
* `default_public_interface_only` - Exposes user's public IP, but does not
expose user's local IP. When this policy is used, WebRTC should only use the
default route used by http. This doesn't expose any local addresses.
* `default_public_and_private_interfaces` - Exposes user's public and local
IPs. When this policy is used, WebRTC should only use the default route used
by http. This also exposes the associated default private address. Default
route is the route chosen by the OS on a multi-homed endpoint.
* `disable_non_proxied_udp` - Does not expose public or local IPs. When this
policy is used, WebRTC should only use TCP to contact peers or servers unless
the proxy server supports UDP.
Setting the WebRTC IP handling policy allows you to control which IPs are
exposed via WebRTC. See [BrowserLeaks](https://browserleaks.com/webrtc) for
more details.
#### `contents.getMediaSourceId(requestWebContents)`
* `requestWebContents` WebContents - Web contents that the id will be registered to.
Returns `string` - The identifier of a WebContents stream. This identifier can be used
with `navigator.mediaDevices.getUserMedia` using a `chromeMediaSource` of `tab`.
The identifier is restricted to the web contents that it is registered to and is only valid for 10 seconds.
#### `contents.getOSProcessId()`
Returns `Integer` - The operating system `pid` of the associated renderer
process.
#### `contents.getProcessId()`
Returns `Integer` - The Chromium internal `pid` of the associated renderer. Can
be compared to the `frameProcessId` passed by frame specific navigation events
(e.g. `did-frame-navigate`)
#### `contents.takeHeapSnapshot(filePath)`
* `filePath` string - Path to the output file.
Returns `Promise<void>` - Indicates whether the snapshot has been created successfully.
Takes a V8 heap snapshot and saves it to `filePath`.
#### `contents.getBackgroundThrottling()`
Returns `boolean` - whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.setBackgroundThrottling(allowed)`
* `allowed` boolean
Controls whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.getType()`
Returns `string` - the type of the webContent. Can be `backgroundPage`, `window`, `browserView`, `remote`, `webview` or `offscreen`.
#### `contents.setImageAnimationPolicy(policy)`
* `policy` string - Can be `animate`, `animateOnce` or `noAnimation`.
Sets the image animation policy for this webContents. The policy only affects
_new_ images, existing images that are currently being animated are unaffected.
This is a known limitation in Chromium, you can force image animation to be
recalculated with `img.src = img.src` which will result in no network traffic
but will update the animation policy.
This corresponds to the [animationPolicy][] accessibility feature in Chromium.
[animationPolicy]: https://developer.chrome.com/docs/extensions/reference/accessibilityFeatures/#property-animationPolicy
### Instance Properties
#### `contents.audioMuted`
A `boolean` property that determines whether this page is muted.
#### `contents.userAgent`
A `string` property that determines the user agent for this web page.
#### `contents.zoomLevel`
A `number` property that determines the zoom level for this web contents.
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. The formula for this is `scale := 1.2 ^ level`.
#### `contents.zoomFactor`
A `number` property that determines the zoom factor for this web contents.
The zoom factor is the zoom percent divided by 100, so 300% = 3.0.
#### `contents.frameRate`
An `Integer` property that sets the frame rate of the web contents to the specified number.
Only values between 1 and 240 are accepted.
Only applicable if *offscreen rendering* is enabled.
#### `contents.id` _Readonly_

A [`WebContents`](web-contents.md) instance that might own this `WebContents`.
#### `contents.devToolsWebContents` _Readonly_
A `WebContents | null` property that represents the of DevTools `WebContents` associated with a given `WebContents`.
**Note:** Users should never store this object because it may become `null`
when the DevTools has been closed.
#### `contents.debugger` _Readonly_
A [`Debugger`](debugger.md) instance for this webContents.
#### `contents.backgroundThrottling`
A `boolean` property that determines whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.mainFrame` _Readonly_
A [`WebFrameMain`](web-frame-main.md) property that represents the top frame of the page's frame hierarchy.

[Bug]: savePage no generated files
|
### 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
16.0.0
### What operating system are you using?
Windows
### Operating System Version
WIN10 20H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
win.webContents.savePage('d:/aaaaaa.html', 'HTMLComplete').then(() => {
console.log('Page was saved successfully.')
}).catch(err => {
console.log(err)
})
it will generate a html page file at d:
### Actual Behavior
savePage has three formats that can be used
if use HTMLComplete
only produced a aaaaaa_files empty folder
if use HTMLonly
No files are generated nor error callbacks are generated
MHTML option works fine
### Testcase Gist URL
_No response_
### Additional Information
_No response_

[Bug]: webContents.print() crashes with a non-null callback
|
### 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
17.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10 version 20H2
### What arch are you using?
x64
### Last Known Working Electron version
17.0.0-beta.2
### Expected Behavior
Calling webContents.print({}, () => {}) will not crash, and will show the system print dialog.
### Actual Behavior
The electron app crashes, even when the aforementioned print() call is encapsulated within a try-catch block.
### Testcase Gist URL
https://gist.github.com/1ab968669f64a7707306e876ab2ff5bc
### Additional Information
Looks pretty similar to #32276, though I'm not able to reproduce the crash in 16.0.5 as the author of that issue claims.
Calling the print() API and providing undefined or null as the callback parameter still shows the dialog, although canceling that print dialog will still result in a crash (as documented in #32684). It's also worth noting that when running in Electron Fiddle, both the print dialog cancellation crash and this new crash share the same error code (3221225477), so I'm wondering if they're related, and if the PR fixing the dialog cancellation crash (#32632) might fix this as well.

### Electron Version
17.0.0-beta.3
### What operating system are you using?
macOS
### Operating System Version
12.2
### What arch are you using?
x64
### Last Known Working Electron version
17.0.0-beta.2
### Expected Behavior
`mainWindow.webContents.openDevTools()` should be able to pass `{mode}` to set a specific dock position.
### Actual Behavior
`mainWindow.webContents.openDevTools()` `mode` value no longer has any effect.
To reproduce, add:
```
mainWindow.webContents.openDevTools({ mode: 'bottom' })
```
to `createWindow` in the default Fiddle. Observe that it opens on the right side instead of the bottom.
### Testcase Gist URL
_No response_
### Additional Information
Error originates [here](https://github.com/electron/electron/blob/b0f315a637b05bc445fc7e6084baa840891c1207/shell/browser/ui/inspectable_web_contents.cc#L589-L592)
This was introduced in this [roll](https://chromium.googlesource.com/chromium/src/+log/98.0.4706.0..98.0.4758.9?n=10000&pretty=full), which contained this [roll](https://chromium.googlesource.com/devtools/devtools-frontend/+log/1b5567f78aca..b6f648d8921e?n=10000) and is almost certainly a result of [this CL](https://chromium-review.googlesource.com/c/devtools/devtools-frontend/+/3264212) which removes legacy globals. We'll need to find an alternative way to fix this, or patch devtools to bring back the globals.

- [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
17.0.0-beta.3
### What operating system are you using?
macOS
### Operating System Version
12.2
### What arch are you using?
x64
### Last Known Working Electron version
17.0.0-beta.2
### Expected Behavior
`mainWindow.webContents.openDevTools()` should be able to pass `{mode}` to set a specific dock position.
### Actual Behavior
`mainWindow.webContents.openDevTools()` `mode` value no longer has any effect.
To reproduce, add:
```
mainWindow.webContents.openDevTools({ mode: 'bottom' })
```
to `createWindow` in the default Fiddle. Observe that it opens on the right side instead of the bottom.

[Bug]: stale process with high cpu usage on windows

### Electron Version
18 nightly, 17.0.0, 15.3.4, 13.6.3
### What operating system are you using?
Windows
### Operating System Version
Win 11 21H2
### What arch are you using?
x64
### Last Known Working Electron version
12.1.2
### Expected Behavior
When I quit Electron, all processes (main, renderer, gpu) are terminated.
### Actual Behavior
When the renderer process is busy during application shutdown, it gets stuck in some weird state and doesn't terminate. Even after work is finished, it remains consuming a complete thread of CPU power.
### Testcase Gist URL
https://gist.github.com/3358b37700ca6fb8b7952ff1d72a209b
### Additional Information
In the fiddle the main process terminates while the renderer process is kept busy. This augments the race condition causing a stale renderer process (let's say in 9 of 10 cases). If you change the timeouts so that the renderer has a chance to finish work before it gets shut down, all processes quit as expected.
I tracked down the first affected version to be 13.0.0-beta.21 resp. 14.0.0-nightly.20210426. Both include a Chromium roll which introduced this issue:
- E14 https://github.com/electron/electron/pull/28462
- E13 https://github.com/electron/electron/pull/28660
Halting the process and analyzing the stacktraces, all share the Chromium method `RequestNewLayerTreeFrameSink`. Please find more discussion around that on Slack.
Only Windows seems to be affected, both 32 and 64bit. **This issue does not occur with renderer sandbox enabled.**
Comment from Milan regarding sandbox:
When sandboxed, the renderer processes are enclosed in a win32 job object, which has the `JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE` flag set, this forces them to be killed when the main process is gone. There was an attempt to do this for non-sandboxed renderers as well (without setting any other limitations through the win32 job object), however it got reverted as it caused some regression caught by tests.
Possibly related: #29056.

[Bug]: stale process with high cpu usage on windows
|
### 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
18 nightly, 17.0.0, 15.3.4, 13.6.3
### What operating system are you using?
Windows
### Operating System Version
Win 11 21H2
### What arch are you using?
x64
### Last Known Working Electron version
12.1.2
### Expected Behavior
When I quit Electron, all processes (main, renderer, gpu) are terminated.
### Actual Behavior
When the renderer process is busy during application shutdown, it gets stuck in some weird state and doesn't terminate. Even after work is finished, it remains consuming a complete thread of CPU power.
### Testcase Gist URL
https://gist.github.com/3358b37700ca6fb8b7952ff1d72a209b
### Additional Information
In the fiddle the main process terminates while the renderer process is kept busy. This augments the race condition causing a stale renderer process (let's say in 9 of 10 cases). If you change the timeouts so that the renderer has a chance to finish work before it gets shut down, all processes quit as expected.
I tracked down the first affected version to be 13.0.0-beta.21 resp. 14.0.0-nightly.20210426. Both include a Chromium roll which introduced this issue:
- E14 https://github.com/electron/electron/pull/28462
- E13 https://github.com/electron/electron/pull/28660
Halting the process and analyzing the stacktraces, all share the Chromium method `RequestNewLayerTreeFrameSink`. Please find more discussion around that on Slack.
Only Windows seems to be affected, both 32 and 64bit. **This issue does not occur with renderer sandbox enabled.**
Comment from Milan regarding sandbox:
When sandboxed, the renderer processes are enclosed in a win32 job object, which has the `JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE` flag set, this forces them to be killed when the main process is gone. There was an attempt to do this for non-sandboxed renderers as well (without setting any other limitations through the win32 job object), however it got reverted as it caused some regression caught by tests.
Possibly related: #29056.

[Bug]: setAsDefaultProtocolClient sets wrong command
|
### 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
16.0.7
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Build 19043
### What arch are you using?
x64
### Last Known Working Electron version
13.1.2
### Expected Behavior
`app.setAsDefaultProtocolClient(protocol, process.execPath, [path.resolve(process.argv[1]), '--arg']);`
to work as expected.
### Actual Behavior
electron will put quotes around the entire list of arguments instead of each individually (if necessary), so the generated command is something like
"C:\example\node_modules\electron\dist\electron.exe" "c:\example --arg" "%1"
which then leads to an error "Unable to find Electron app at c:\example --args".
### Testcase Gist URL
!!! Please note that by the nature of setAsDefaultProtocolClient this testcase will make a systemwide setting!
https://gist.github.com/a1f2fdbe04624b6f7a6877a89581143c

[Bug]: setAsDefaultProtocolClient sets wrong command
|
### 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
16.0.7
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Build 19043
### What arch are you using?
x64
### Last Known Working Electron version
13.1.2
### Expected Behavior
`app.setAsDefaultProtocolClient(protocol, process.execPath, [path.resolve(process.argv[1]), '--arg']);`
to work as expected.
### Actual Behavior
electron will put quotes around the entire list of arguments instead of each individually (if necessary), so the generated command is something like
"C:\example\node_modules\electron\dist\electron.exe" "c:\example --arg" "%1"
which then leads to an error "Unable to find Electron app at c:\example --args".
### Testcase Gist URL
!!! Please note that by the nature of setAsDefaultProtocolClient this testcase will make a systemwide setting!
https://gist.github.com/a1f2fdbe04624b6f7a6877a89581143c

[Bug]: BrowserWindow.showInactive Will Restore Maximized Window
|
### 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
17.0.0-alpha.6
### 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
`BrowserWindow.showInactive` should not restore a maximized window
### Actual Behavior
`BrowserWindow.showInactive` does restore a maximized window
### Testcase Gist URL
https://gist.github.com/9f2c69b089f2155859bb0b439aefb668
### Additional Information
The provided gist is a test so it should be runnable by `bugbot`. I've confirmed the behavior on Windows, macOS seems unaffected, I haven't tested Linux.
~@ckerr, could you test Linux? It might be similar to #32350 where it affects both Windows and Linux but not macOS.~
Root cause may be upstream in Chromium, `ShowInactive` in Electron just passes through to `ShowInactive` on the widget, there's really no logic present.

[Bug]: BrowserWindow.showInactive Will Restore Maximized Window
|
### 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
17.0.0-alpha.6
### 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
`BrowserWindow.showInactive` should not restore a maximized window
### Actual Behavior
`BrowserWindow.showInactive` does restore a maximized window
### Testcase Gist URL
https://gist.github.com/9f2c69b089f2155859bb0b439aefb668
### Additional Information
The provided gist is a test so it should be runnable by `bugbot`. I've confirmed the behavior on Windows, macOS seems unaffected, I haven't tested Linux.
~@ckerr, could you test Linux? It might be similar to #32350 where it affects both Windows and Linux but not macOS.~
Root cause may be upstream in Chromium, `ShowInactive` in Electron just passes through to `ShowInactive` on the widget, there's really no logic present.

### Last Known Working Electron version

### Additional Information
The provided gist is a test so it should be runnable by `bugbot`. I've confirmed the behavior on Windows, macOS seems unaffected, I haven't tested Linux.
~@ckerr, could you test Linux? It might be similar to #32350 where it affects both Windows and Linux but not macOS.~
Root cause may be upstream in Chromium, `ShowInactive` in Electron just passes through to `ShowInactive` on the widget, there's really no logic present.

Opened windows will be closed when the opener window closes.
|
* Electron version: 1.7.5, 1.7.9
* Operating system: Windows 10 x64, Windows 7 x86
### Expected behavior
Opened windows will remain open when closing the opener window.
### Actual behavior
Opened windows will automatically close when the opener window is closed.
### How to reproduce
1. Open an electron instance with a BrowserWindow (window A).
2. Navigate to https://www.w3schools.com/jsref/met_win_open.asp (or similar pages)
3. Open a new window (window B) by clicking the "Try It Yourself" button.
4. Open a new window (window C) by clicking the "Try It" button in Window B.
4. Close window B (opener window of window C)
Result: Window C closes.
This only closes the opened windows (and the opened windows in the opened window, eg.) when closing the opener window. All other windows remain unaffected:
Closing window A results in the closing of window B and window C.

# Opening windows from the renderer
There are several ways to control how windows are created from trusted or
untrusted content within a renderer. Windows can be created from the renderer in two ways:
* clicking on links or submitting forms adorned with `target=_blank`
* JavaScript calling `window.open()`
For same-origin content, the new window is created within the same process,
enabling the parent to access the child window directly. This can be very
useful for app sub-windows that act as preference panels, or similar, as the
parent can render to the sub-window directly, as if it were a `div` in the
parent. This is the same behavior as in the browser.
Electron pairs this native Chrome `Window` with a BrowserWindow under the hood.
You can take advantage of all the customization available when creating a
BrowserWindow in the main process by using `webContents.setWindowOpenHandler()`
for renderer-created windows.
BrowserWindow constructor options are set by, in increasing precedence
order: parsed options from the `features` string from `window.open()`,
security-related webPreferences inherited from the parent, and options given by
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
Note that `webContents.setWindowOpenHandler` has final say and full privilege
because it is invoked in the main process.
### `window.open(url[, frameName][, features])`
* `url` string
* `frameName` string (optional)
* `features` string (optional)
Returns [`Window`](https://developer.mozilla.org/en-US/docs/Web/API/Window) | null
`features` is a comma-separated key-value list, following the standard format of
the browser. Electron will parse `BrowserWindowConstructorOptions` out of this
list where possible, for convenience. For full control and better ergonomics,
consider using `webContents.setWindowOpenHandler` to customize the
BrowserWindow creation.
A subset of `WebPreferences` can be set directly,
unnested, from the features string: `zoomFactor`, `nodeIntegration`, `preload`,
`javascript`, `contextIsolation`, and `webviewTag`.
For example:
```js
window.open('https://github.com', '_blank', 'top=500,left=200,frame=false,nodeIntegration=no')
```
**Notes:**
* Node integration will always be disabled in the opened `window` if it is
disabled on the parent window.
* Context isolation will always be enabled in the opened `window` if it is
enabled on the parent window.
* JavaScript will always be disabled in the opened `window` if it is disabled on
the parent window.
* Non-standard features (that are not handled by Chromium or Electron) given in
`features` will be passed to any registered `webContents`'s
`did-create-window` event handler in the `options` argument.
* `frameName` follows the specification of `windowName` located in the [native documentation](https://developer.mozilla.org/en-US/docs/Web/API/Window/open#parameters).
* When opening `about:blank`, the child window's `WebPreferences` will be copied
from the parent window, and there is no way to override it because Chromium
skips browser side navigation in this case.
To customize or cancel the creation of the window, you can optionally set an
override handler with `webContents.setWindowOpenHandler()` from the main
process. Returning `{ action: 'deny' }` cancels the window. Returning `{
action: 'allow', overrideBrowserWindowOptions: { ... } }` will allow opening
the window and setting the `BrowserWindowConstructorOptions` to be used when
creating the window. Note that this is more powerful than passing options
through the feature string, as the renderer has more limited privileges in
deciding security preferences than the main process.
### Native `Window` example
```javascript
// main.js
const mainWindow = new BrowserWindow()
// In this example, only windows with the `about:blank` url will be created.
// All other urls will be blocked.
mainWindow.webContents.setWindowOpenHandler(({ url }) => {
if (url === 'about:blank') {
return {
action: 'allow',
overrideBrowserWindowOptions: {
frame: false,
fullscreenable: false,
backgroundColor: 'black',
webPreferences: {
preload: 'my-child-window-preload-script.js'
}
}
}
}
return { action: 'deny' }
})
```
```javascript
// renderer process (mainWindow)
const childWindow = window.open('', 'modal')
childWindow.document.write('<h1>Hello</h1>')
```

Opened windows will be closed when the opener window closes.
|
* Electron version: 1.7.5, 1.7.9
* Operating system: Windows 10 x64, Windows 7 x86
### Expected behavior
Opened windows will remain open when closing the opener window.
### Actual behavior
Opened windows will automatically close when the opener window is closed.
### How to reproduce
1. Open an electron instance with a BrowserWindow (window A).
2. Navigate to https://www.w3schools.com/jsref/met_win_open.asp (or similar pages)
3. Open a new window (window B) by clicking the "Try It Yourself" button.
4. Open a new window (window C) by clicking the "Try It" button in Window B.
4. Close window B (opener window of window C)
Result: Window C closes.
This only closes the opened windows (and the opened windows in the opened window, eg.) when closing the opener window. All other windows remain unaffected:
Closing window A results in the closing of window B and window C.

Opened windows will be closed when the opener window closes.
|
* Electron version: 1.7.5, 1.7.9
* Operating system: Windows 10 x64, Windows 7 x86
### Expected behavior
Opened windows will remain open when closing the opener window.
### Actual behavior
Opened windows will automatically close when the opener window is closed.
### How to reproduce
1. Open an electron instance with a BrowserWindow (window A).
2. Navigate to https://www.w3schools.com/jsref/met_win_open.asp (or similar pages)
3. Open a new window (window B) by clicking the "Try It Yourself" button.
4. Open a new window (window C) by clicking the "Try It" button in Window B.
4. Close window B (opener window of window C)
Result: Window C closes.
This only closes the opened windows (and the opened windows in the opened window, eg.) when closing the opener window. All other windows remain unaffected:
Closing window A results in the closing of window B and window C.

# Opening windows from the renderer
There are several ways to control how windows are created from trusted or
untrusted content within a renderer. Windows can be created from the renderer in two ways:
* clicking on links or submitting forms adorned with `target=_blank`
* JavaScript calling `window.open()`
For same-origin content, the new window is created within the same process,
enabling the parent to access the child window directly. This can be very
useful for app sub-windows that act as preference panels, or similar, as the
parent can render to the sub-window directly, as if it were a `div` in the
parent. This is the same behavior as in the browser.
Electron pairs this native Chrome `Window` with a BrowserWindow under the hood.
You can take advantage of all the customization available when creating a
BrowserWindow in the main process by using `webContents.setWindowOpenHandler()`
for renderer-created windows.
BrowserWindow constructor options are set by, in increasing precedence
order: parsed options from the `features` string from `window.open()`,
security-related webPreferences inherited from the parent, and options given by
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
Note that `webContents.setWindowOpenHandler` has final say and full privilege
because it is invoked in the main process.
### `window.open(url[, frameName][, features])`
* `url` string
* `frameName` string (optional)
* `features` string (optional)
Returns [`Window`](https://developer.mozilla.org/en-US/docs/Web/API/Window) | null
`features` is a comma-separated key-value list, following the standard format of
the browser. Electron will parse `BrowserWindowConstructorOptions` out of this
list where possible, for convenience. For full control and better ergonomics,
consider using `webContents.setWindowOpenHandler` to customize the
BrowserWindow creation.
A subset of `WebPreferences` can be set directly,
unnested, from the features string: `zoomFactor`, `nodeIntegration`, `preload`,
`javascript`, `contextIsolation`, and `webviewTag`.
For example:
```js
window.open('https://github.com', '_blank', 'top=500,left=200,frame=false,nodeIntegration=no')
```
**Notes:**
* Node integration will always be disabled in the opened `window` if it is
disabled on the parent window.
* Context isolation will always be enabled in the opened `window` if it is
enabled on the parent window.
* JavaScript will always be disabled in the opened `window` if it is disabled on
the parent window.
* Non-standard features (that are not handled by Chromium or Electron) given in
`features` will be passed to any registered `webContents`'s
`did-create-window` event handler in the `options` argument.
* `frameName` follows the specification of `windowName` located in the [native documentation](https://developer.mozilla.org/en-US/docs/Web/API/Window/open#parameters).
* When opening `about:blank`, the child window's `WebPreferences` will be copied
from the parent window, and there is no way to override it because Chromium
skips browser side navigation in this case.
To customize or cancel the creation of the window, you can optionally set an
override handler with `webContents.setWindowOpenHandler()` from the main
process. Returning `{ action: 'deny' }` cancels the window. Returning `{
action: 'allow', overrideBrowserWindowOptions: { ... } }` will allow opening
the window and setting the `BrowserWindowConstructorOptions` to be used when
creating the window. Note that this is more powerful than passing options
through the feature string, as the renderer has more limited privileges in
deciding security preferences than the main process.
### Native `Window` example
```javascript
// main.js
const mainWindow = new BrowserWindow()
// In this example, only windows with the `about:blank` url will be created.
// All other urls will be blocked.
mainWindow.webContents.setWindowOpenHandler(({ url }) => {
if (url === 'about:blank') {
return {
action: 'allow',
overrideBrowserWindowOptions: {
frame: false,
fullscreenable: false,
backgroundColor: 'black',
webPreferences: {
preload: 'my-child-window-preload-script.js'
}
}
}
}
return { action: 'deny' }
})
```
```javascript
// renderer process (mainWindow)
const childWindow = window.open('', 'modal')
childWindow.document.write('<h1>Hello</h1>')
```

Opened windows will be closed when the opener window closes.
|
* Electron version: 1.7.5, 1.7.9
* Operating system: Windows 10 x64, Windows 7 x86
### Expected behavior
Opened windows will remain open when closing the opener window.
### Actual behavior
Opened windows will automatically close when the opener window is closed.
### How to reproduce
1. Open an electron instance with a BrowserWindow (window A).
2. Navigate to https://www.w3schools.com/jsref/met_win_open.asp (or similar pages)
3. Open a new window (window B) by clicking the "Try It Yourself" button.
4. Open a new window (window C) by clicking the "Try It" button in Window B.
4. Close window B (opener window of window C)
Result: Window C closes.
This only closes the opened windows (and the opened windows in the opened window, eg.) when closing the opener window. All other windows remain unaffected:

Opened windows will be closed when the opener window closes.
|
* Electron version: 1.7.5, 1.7.9
* Operating system: Windows 10 x64, Windows 7 x86
### Expected behavior
Opened windows will remain open when closing the opener window.
### Actual behavior
Opened windows will automatically close when the opener window is closed.
### How to reproduce
1. Open an electron instance with a BrowserWindow (window A).
2. Navigate to https://www.w3schools.com/jsref/met_win_open.asp (or similar pages)
3. Open a new window (window B) by clicking the "Try It Yourself" button.
4. Open a new window (window C) by clicking the "Try It" button in Window B.
4. Close window B (opener window of window C)
Result: Window C closes.
This only closes the opened windows (and the opened windows in the opened window, eg.) when closing the opener window. All other windows remain unaffected:
Closing window A results in the closing of window B and window C.

[Bug]: unable to resize height when maxWidth set

### Electron Version
17.0.1
### What operating system are you using?
macOS
### Operating System Version
12.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
16.0.9
### Expected Behavior
When setting `maxWidth` but not a `maxHeight`, I expect the window to resizable in the y direction.
### Actual Behavior
Unable to resize window in y direction. Also, removing `minWidth` to allow window to shrink, causes stuttering and mac's beach-ball cursor to show.
### Testcase Gist URL
https://gist.github.com/eab3c4ec605b8b942cece3d05e7f749c

[Bug]: unable to resize height when maxWidth set
|
### 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
17.0.1
### What operating system are you using?
macOS
### Operating System Version
12.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
16.0.9
### Expected Behavior
When setting `maxWidth` but not a `maxHeight`, I expect the window to resizable in the y direction.
### Actual Behavior
Unable to resize window in y direction. Also, removing `minWidth` to allow window to shrink, causes stuttering and mac's beach-ball cursor to show.
### Testcase Gist URL
https://gist.github.com/eab3c4ec605b8b942cece3d05e7f749c

[Bug]: Dark mode in Devtools is not working on the latest 16.0.0 - 16.0.8 / 17.0.0
|
### 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 feature request that matches the one I want to file, without success.
### Electron Version
16.0.0 - 16.0.5
### What operating system are you using?
Windows
### Operating System Version
Windows 7 x64 SP1
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Devtools should have a dark mode applied when the settings is set to 'Dark Mode'.
### Actual Behavior
When switching to dark mode, it displays the message that 'Devtools requires a reload' but when I click on the reload button it does nothing. Restarting the app has no effect as well and stays on the light mode.
This worked fine on the previous 15.3.2 version.
### Testcase Gist URL
_No response_
### Additional Information
One thing I noticed, when updating from the last version (15.3.2) the dev tools will show up with dark mode enabled on the first run but on subsequent runs, it reverts back to light mode.

[Bug]: Dark mode in Devtools is not working on the latest 16.0.0 - 16.0.8 / 17.0.0
|
### 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 feature request that matches the one I want to file, without success.
### Electron Version
16.0.0 - 16.0.5
### What operating system are you using?
Windows
### Operating System Version
Windows 7 x64 SP1
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Devtools should have a dark mode applied when the settings is set to 'Dark Mode'.
### Actual Behavior
When switching to dark mode, it displays the message that 'Devtools requires a reload' but when I click on the reload button it does nothing. Restarting the app has no effect as well and stays on the light mode.
This worked fine on the previous 15.3.2 version.
### Testcase Gist URL
_No response_
### Additional Information
One thing I noticed, when updating from the last version (15.3.2) the dev tools will show up with dark mode enabled on the first run but on subsequent runs, it reverts back to light mode.

[Bug]: Dark mode in Devtools is not working on the latest 16.0.0 - 16.0.8 / 17.0.0
|
### 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 feature request that matches the one I want to file, without success.
### Electron Version
16.0.0 - 16.0.5
### What operating system are you using?
Windows
### Operating System Version
Windows 7 x64 SP1
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Devtools should have a dark mode applied when the settings is set to 'Dark Mode'.
### Actual Behavior
When switching to dark mode, it displays the message that 'Devtools requires a reload' but when I click on the reload button it does nothing. Restarting the app has no effect as well and stays on the light mode.
This worked fine on the previous 15.3.2 version.
### Testcase Gist URL
_No response_
### Additional Information
One thing I noticed, when updating from the last version (15.3.2) the dev tools will show up with dark mode enabled on the first run but on subsequent runs, it reverts back to light mode.

- [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 feature request that matches the one I want to file, without success.
### Electron Version
16.0.0 - 16.0.5
### What operating system are you using?
Windows
### Operating System Version
Windows 7 x64 SP1
### What arch are you using?
x64
### Last Known Working Electron version
15.3.4
### Expected Behavior
Devtools should have a dark mode applied when the settings is set to 'Dark Mode'.
### Actual Behavior
When switching to dark mode, it displays the message that 'Devtools requires a reload' but when I click on the reload button it does nothing. Restarting the app has no effect as well and stays on the light mode.
This worked fine on the previous 15.3.2 version.
### Testcase Gist URL
_No response_
### Additional Information
One thing I noticed, when updating from the last version (15.3.2) the dev tools will show up with dark mode enabled on the first run but on subsequent runs, it reverts back to light mode.

Support Chromium's command-line switch --unsafely-treat-insecure-origin-as-secure
|
**Is your feature request related to a problem? Please describe.**
Notifications, Geolocation, Device motion/orientation, EME, getUserMedia, AppCache require a secure origin to work in Chromium. HTTP URLs are not considered secure.
That's why Chromium provides the command-line switch
`--unsafely-treat-insecure-origin-as-secure="$url"` to circumvent this problem.
Unfortunately it's not working in Electron.
**Describe the solution you'd like**
Please make it work. In the renderer. I'd suggest simply like
```
new BrowserWindow({
webPreferences: {
additionalArguments: {
'--unsafely-treat-insecure-origin-as-secure', 'http://insecure-origin'
}
}
```
Or a new option `considerSecure: String[]` to `BrowserWindow.webPreferences`.
I guess it should be not too hard to implement since Chromium already supports it and it seems to get lost only in the process of Electron integration.
**Describe alternatives you've considered**
- `app.commandLine.appendSwitch('unsafely-treat-insecure-origin-as-secure', $url)` in the main thread
- Invisible [BrowserWindow](https://github.com/electron/electron/blob/master/docs/api/browser-window.md) with secure origin + IPC
- `<iframe>` on a secure origin
- localhost-Proxy
- Using Data URLs in [loadURL](https://github.com/electron/electron/blob/master/docs/api/browser-window.md#winloadurlurl-options): `data:text/html,<script>new Notification("hi")</script>`
- webFrame.registerURLSchemeAsPrivileged
**Additional context**
'Deprecating Powerful Features on Insecure Origins' https://goo.gl/rStTGz
When the flag is set in Chromium a message appears under the address bar, saying that
'You are using an unsupported command-line flag'.
Nonetheless the features are then working on the origin treated securely.

Support Chromium's command-line switch --unsafely-treat-insecure-origin-as-secure
|
**Is your feature request related to a problem? Please describe.**
Notifications, Geolocation, Device motion/orientation, EME, getUserMedia, AppCache require a secure origin to work in Chromium. HTTP URLs are not considered secure.
That's why Chromium provides the command-line switch
`--unsafely-treat-insecure-origin-as-secure="$url"` to circumvent this problem.
Unfortunately it's not working in Electron.
**Describe the solution you'd like**
Please make it work. In the renderer. I'd suggest simply like
```
new BrowserWindow({
webPreferences: {
additionalArguments: {
'--unsafely-treat-insecure-origin-as-secure', 'http://insecure-origin'
}
}
```
Or a new option `considerSecure: String[]` to `BrowserWindow.webPreferences`.
I guess it should be not too hard to implement since Chromium already supports it and it seems to get lost only in the process of Electron integration.
**Describe alternatives you've considered**
- `app.commandLine.appendSwitch('unsafely-treat-insecure-origin-as-secure', $url)` in the main thread
- Invisible [BrowserWindow](https://github.com/electron/electron/blob/master/docs/api/browser-window.md) with secure origin + IPC
- `<iframe>` on a secure origin
- localhost-Proxy
- Using Data URLs in [loadURL](https://github.com/electron/electron/blob/master/docs/api/browser-window.md#winloadurlurl-options): `data:text/html,<script>new Notification("hi")</script>`
- webFrame.registerURLSchemeAsPrivileged
**Additional context**
'Deprecating Powerful Features on Insecure Origins' https://goo.gl/rStTGz
When the flag is set in Chromium a message appears under the address bar, saying that
'You are using an unsupported command-line flag'.
Nonetheless the features are then working on the origin treated securely.

[Bug]: BrowserWindow.maximize Doesn't Fire show Event for Unshown Window
|
### 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.20220207
### 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
An unshown window becomes shown if `maximize()` is called, so a 'show' event should be fired.
### Actual Behavior
A 'show' event is not fired.
### Testcase Gist URL
https://gist.github.com/b86e40446891294b1d1f3cfc19202c89
### Additional Information
I've only tested this on Windows so far. On macOS, #32947 means the window isn't shown anyway, so this issue is not applicable there for the moment.

[Bug]: BrowserWindow.maximize Doesn't Fire show Event for Unshown Window
|
### 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.20220207
### 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
An unshown window becomes shown if `maximize()` is called, so a 'show' event should be fired.
### Actual Behavior
A 'show' event is not fired.
### Testcase Gist URL
https://gist.github.com/b86e40446891294b1d1f3cfc19202c89
### Additional Information
I've only tested this on Windows so far. On macOS, #32947 means the window isn't shown anyway, so this issue is not applicable there for the moment.

[Bug]: BrowserWindow.maximize Does Not Show Window on macOS
|
### 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.20220209
### What operating system are you using?
macOS
### Operating System Version
macOS 11.6.2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Maximizing a window which isn't being shown should show the window. According to the docs for `BrowserWindow.maximize()`:
> Maximizes the window. This will also show (but not focus) the window if it isn't being displayed already.
### Actual Behavior
On macOS, the window is not shown, but `window.isMaximized()` returns true, and a subsequent `window.show()` will show a maximized window as expected.
### Testcase Gist URL
https://gist.github.com/09e5ef031f69be2cce1e23c5174d6e5b
### Additional Information
Tested on Windows 10 and Ubuntu and it works as expected, so this looks to be just macOS.

[Bug]: BrowserWindow.maximize Does Not Show Window on macOS
|
### 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.20220209
### What operating system are you using?
macOS
### Operating System Version
macOS 11.6.2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Maximizing a window which isn't being shown should show the window. According to the docs for `BrowserWindow.maximize()`:
> Maximizes the window. This will also show (but not focus) the window if it isn't being displayed already.
### Actual Behavior
On macOS, the window is not shown, but `window.isMaximized()` returns true, and a subsequent `window.show()` will show a maximized window as expected.
### Testcase Gist URL
https://gist.github.com/09e5ef031f69be2cce1e23c5174d6e5b
### Additional Information
Tested on Windows 10 and Ubuntu and it works as expected, so this looks to be just macOS.

### Electron Version
19.0.0-nightly.20220207
### 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
An unshown window becomes shown if `maximize()` is called, so a 'show' event should be fired.
### Actual Behavior
A 'show' event is not fired.
### Testcase Gist URL
https://gist.github.com/b86e40446891294b1d1f3cfc19202c89
### Additional Information
I've only tested this on Windows so far. On macOS, #32947 means the window isn't shown anyway, so this issue is not applicable there for the moment.

[Bug]: BrowserWindow.maximize Doesn't Fire show Event for Unshown Window
|
### 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.20220207
### 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
An unshown window becomes shown if `maximize()` is called, so a 'show' event should be fired.
### Actual Behavior
A 'show' event is not fired.
### Testcase Gist URL
https://gist.github.com/b86e40446891294b1d1f3cfc19202c89
### Additional Information
I've only tested this on Windows so far. On macOS, #32947 means the window isn't shown anyway, so this issue is not applicable there for the moment.

[Bug]: BrowserWindow.maximize Does Not Show Window on macOS
|
### 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.20220209
### What operating system are you using?
macOS
### Operating System Version
macOS 11.6.2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Maximizing a window which isn't being shown should show the window. According to the docs for `BrowserWindow.maximize()`:
> Maximizes the window. This will also show (but not focus) the window if it isn't being displayed already.
### Actual Behavior
On macOS, the window is not shown, but `window.isMaximized()` returns true, and a subsequent `window.show()` will show a maximized window as expected.
### Testcase Gist URL
https://gist.github.com/09e5ef031f69be2cce1e23c5174d6e5b
### Additional Information
Tested on Windows 10 and Ubuntu and it works as expected, so this looks to be just macOS.

[Bug]: BrowserWindow.maximize Does Not Show Window on macOS
|
### 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.20220209
### What operating system are you using?
macOS
### Operating System Version
macOS 11.6.2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Maximizing a window which isn't being shown should show the window. According to the docs for `BrowserWindow.maximize()`:
> Maximizes the window. This will also show (but not focus) the window if it isn't being displayed already.
### Actual Behavior
On macOS, the window is not shown, but `window.isMaximized()` returns true, and a subsequent `window.show()` will show a maximized window as expected.
### Testcase Gist URL
https://gist.github.com/09e5ef031f69be2cce1e23c5174d6e5b
### Additional Information
Tested on Windows 10 and Ubuntu and it works as expected, so this looks to be just macOS.

[Bug]: BrowserWindow.maximize Does Not Show Window on macOS
|
### 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.20220209
### What operating system are you using?
macOS
### Operating System Version
macOS 11.6.2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Maximizing a window which isn't being shown should show the window. According to the docs for `BrowserWindow.maximize()`:
> Maximizes the window. This will also show (but not focus) the window if it isn't being displayed already.
### Actual Behavior
On macOS, the window is not shown, but `window.isMaximized()` returns true, and a subsequent `window.show()` will show a maximized window as expected.
### Testcase Gist URL
https://gist.github.com/09e5ef031f69be2cce1e23c5174d6e5b
### Additional Information
Tested on Windows 10 and Ubuntu and it works as expected, so this looks to be just macOS.

[Bug]: Adding/Removing Display Changes Window Size
|
### 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.20220207
### 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
Adding or removing a display will not change the size of a `BrowserWindow`.
### Actual Behavior
Adding or removing a display does change the size of a `BrowserWindow`.
### Testcase Gist URL
https://gist.github.com/7f8c673311b123fa4f7fe3444b4d0fea
### Additional Information
Gist of course will only work if you have a second monitor to test with - it uses the 'display-added' event.
On Windows the width and height of a window shrinks by 1 pixel every time a display is added or removed. Other platforms are not affected.

[Bug]: Adding/Removing Display Changes Window Size
|
### 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.20220207
### 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
Adding or removing a display will not change the size of a `BrowserWindow`.
### Actual Behavior
Adding or removing a display does change the size of a `BrowserWindow`.
### Testcase Gist URL
https://gist.github.com/7f8c673311b123fa4f7fe3444b4d0fea
### Additional Information
Gist of course will only work if you have a second monitor to test with - it uses the 'display-added' event.
On Windows the width and height of a window shrinks by 1 pixel every time a display is added or removed. Other platforms are not affected.

### Electron Version
15.0.2
### What operating system are you using?
Ubuntu
### Operating System Version
Linux rrouwprlc0068 5.4.0-89-generic #100-Ubuntu SMP Fri Sep 24 14:50:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux, Ubuntu 20.04.3 LTS, GNOME Version 3.36.8, OS Type 64-bit
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Network service should not crash and the error `[15:1102/154337.143944:ERROR:network_service_instance_impl.cc(333)] Network service crashed, restarting service.`, to not appear in the logs.
### Actual Behavior
Sporadically, when I run Electron inside a Docker container, I get the following error:
[15:1102/154337.143944:ERROR:network_service_instance_impl.cc(333)] Network service crashed, restarting service.
Which causes partially rendering of the front-end application that is loaded with `win.loadURL` on localhost.
The issue seems very similar to https://bbs.archlinux.org/viewtopic.php?id=268123, but nothing from the suggestions works consinstently.
Also, when closing the Electron window, I get an error
Error: ERR_FAILED (-2) loading 'https://localhost:{port}/{path_to}/index.html'
at rejectAndCleanup (node:electron/js2c/browser_init:165:7486)
at Object.stopLoadingListener (node:electron/js2c/browser_init:165:7861)
at Object.emit (node:events:394:28) {
errno: -2,
code: 'ERR_FAILED',
url: 'https://localhost:{port}/{path_to}/index.html'
} [EOL]
Which is caught inside the main.js when executing await `win.loadURL(url)`
Also, in the browser window console, there is an error:
ERROR Error: Uncaught (in promise): ChunkLoadError: Loading chunk 108 failed.
(timeout: https://localhost:{port}/{path_to}/108.da4993913b4a27951976.js)
ChunkLoadError: Loading chunk 108 failed.
Any ideas on the issue?

### Electron Version
15.0.2
### What operating system are you using?
Ubuntu
### Operating System Version
Linux rrouwprlc0068 5.4.0-89-generic #100-Ubuntu SMP Fri Sep 24 14:50:10 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux, Ubuntu 20.04.3 LTS, GNOME Version 3.36.8, OS Type 64-bit
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Network service should not crash and the error `[15:1102/154337.143944:ERROR:network_service_instance_impl.cc(333)] Network service crashed, restarting service.`, to not appear in the logs.
### Actual Behavior
Sporadically, when I run Electron inside a Docker container, I get the following error:
[15:1102/154337.143944:ERROR:network_service_instance_impl.cc(333)] Network service crashed, restarting service.
Which causes partially rendering of the front-end application that is loaded with `win.loadURL` on localhost.
The issue seems very similar to https://bbs.archlinux.org/viewtopic.php?id=268123, but nothing from the suggestions works consinstently.
Also, when closing the Electron window, I get an error
Error: ERR_FAILED (-2) loading 'https://localhost:{port}/{path_to}/index.html'
at rejectAndCleanup (node:electron/js2c/browser_init:165:7486)
at Object.stopLoadingListener (node:electron/js2c/browser_init:165:7861)
at Object.emit (node:events:394:28) {
errno: -2,
code: 'ERR_FAILED',
url: 'https://localhost:{port}/{path_to}/index.html'
} [EOL]
Which is caught inside the main.js when executing await `win.loadURL(url)`
Also, in the browser window console, there is an error:
ERROR Error: Uncaught (in promise): ChunkLoadError: Loading chunk 108 failed.
(timeout: https://localhost:{port}/{path_to}/108.da4993913b4a27951976.js)
ChunkLoadError: Loading chunk 108 failed.
Any ideas on the issue?

title: Inter-Process Communication

# Inter-Process Communication
Inter-process communication (IPC) is a key part of building feature-rich desktop applications
in Electron. Because the main and renderer processes have different responsibilities in
Electron's process model, IPC is the only way to perform many common tasks, such as calling a
native API from your UI or triggering changes in your web contents from native menus.
## IPC channels
In Electron, processes communicate by passing messages through developer-defined "channels"
with the [`ipcMain`] and [`ipcRenderer`] modules. These channels are
**arbitrary** (you can name them anything you want) and **bidirectional** (you can use the
same channel name for both modules).
In this guide, we'll be going over some fundamental IPC patterns with concrete examples that
you can use as a reference for your app code.
## Understanding context-isolated processes
Before proceeding to implementation details, you should be familiar with the idea of using a
[preload script] to import Node.js and Electron modules in a context-isolated renderer process.
* For a full overview of Electron's process model, you can read the [process model docs].
* For a primer into exposing APIs from your preload script using the `contextBridge` module, check
out the [context isolation tutorial].
## Pattern 1: Renderer to main (one-way)
To fire a one-way IPC message from a renderer process to the main process, you can use the
[`ipcRenderer.send`] API to send a message that is then received by the [`ipcMain.on`] API.
You usually use this pattern to call a main process API from your web contents. We'll demonstrate
this pattern by creating a simple app that can programmatically change its window title.
For this demo, you'll need to add code to your main process, your renderer process, and a preload
script. The full code is below, but we'll be explaining each file individually in the following
sections.
```fiddle docs/fiddles/ipc/pattern-1
```
### 1. Listen for events with `ipcMain.on`
In the main process, set an IPC listener on the `set-title` channel with the `ipcMain.on` API:
```javascript {6-10,22} title='main.js (Main Process)'
const {app, BrowserWindow, ipcMain} = require('electron')
const path = require('path')
//...
function handleSetTitle (event, title) {
const webContents = event.sender
const win = BrowserWindow.fromWebContents(webContents)
win.setTitle(title)
}
function createWindow () {
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
mainWindow.loadFile('index.html')
}
app.whenReady().then(() => {
ipcMain.on('set-title', handleSetTitle)
createWindow()
}
//...
```
The above `handleSetTitle` callback has two parameters: an [IpcMainEvent] structure and a
`title` string. Whenever a message comes through the `set-title` channel, this function will
find the BrowserWindow instance attached to the message sender and use the `win.setTitle`
API on it.
:::info
Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
:::
### 2. Expose `ipcRenderer.send` via preload
To send messages to the listener created above, you can use the `ipcRenderer.send` API.
By default, the renderer process has no Node.js or Electron module access. As an app developer,
you need to choose which APIs to expose from your preload script using the `contextBridge` API.
In your preload script, add the following code, which will expose a global `window.electronAPI`
variable to your renderer process.
```javascript title='preload.js (Preload Script)'
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld('electronAPI', {
setTitle: (title) => ipcRenderer.send('set-title', title)
})
```
At this point, you'll be able to use the `window.electronAPI.setTitle()` function in the renderer
process.
:::caution Security warning
We don't directly expose the whole `ipcRenderer.send` API for [security reasons]. Make sure to
limit the renderer's access to Electron APIs as much as possible.
:::
### 3. Build the renderer process UI
In our BrowserWindow's loaded HTML file, add a basic user interface consisting of a text input
and a button:
```html {11-12} title='index.html'
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<title>Hello World!</title>
</head>
<body>
Title: <input id="title"/>
<button id="btn" type="button">Set</button>
<script src="./renderer.js"></script>
</body>
</html>
```
To make these elements interactive, we'll be adding a few lines of code in the imported
`renderer.js` file that leverages the `window.electronAPI` functionality exposed from the preload
script:
```javascript title='renderer.js (Renderer Process)'
const setButton = document.getElementById('btn')
const titleInput = document.getElementById('title')
setButton.addEventListener('click', () => {
const title = titleInput.value
window.electronAPI.setTitle(title)
});
```
At this point, your demo should be fully functional. Try using the input field and see what happens
to your BrowserWindow title!
## Pattern 2: Renderer to main (two-way)
A common application for two-way IPC is calling a main process module from your renderer process
code and waiting for a result. This can be done by using [`ipcRenderer.invoke`] paired with
[`ipcMain.handle`].
In the following example, we'll be opening a native file dialog from the renderer process and
returning the selected file's path.
For this demo, you'll need to add code to your main process, your renderer process, and a preload
script. The full code is below, but we'll be explaining each file individually in the following
sections.
```fiddle docs/fiddles/ipc/pattern-2
```
### 1. Listen for events with `ipcMain.handle`
In the main process, we'll be creating a `handleFileOpen()` function that calls
`dialog.showOpenDialog` and returns the value of the file path selected by the user. This function
is used as a callback whenever an `ipcRender.invoke` message is sent through the `dialog:openFile`
channel from the renderer process. The return value is then returned as a Promise to the original
`invoke` call.
:::caution A word on error handling
Errors thrown through `handle` in the main process are not transparent as they
are serialized and only the `message` property from the original error is
provided to the renderer process. Please refer to
[#24427](https://github.com/electron/electron/issues/24427) for details.
:::
```javascript {6-13,25} title='main.js (Main Process)'
const { BrowserWindow, dialog, ipcMain } = require('electron')
const path = require('path')
//...
async function handleFileOpen() {
const { canceled, filePaths } = await dialog.showOpenDialog()
if (canceled) {
return
} else {
return filePaths[0]
}
}
function createWindow () {
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
mainWindow.loadFile('index.html')
}
app.whenReady(() => {
ipcMain.handle('dialog:openFile', handleFileOpen)
createWindow()
})
//...
```
:::tip on channel names
The `dialog:` prefix on the IPC channel name has no effect on the code. It only serves
as a namespace that helps with code readability.
:::
:::info
Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
:::
### 2. Expose `ipcRenderer.invoke` via preload
In the preload script, we expose a one-line `openFile` function that calls and returns the value of
`ipcRenderer.invoke('dialog:openFile')`. We'll be using this API in the next step to call the
native dialog from our renderer's user interface.
```javascript title='preload.js (Preload Script)'
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld('electronAPI', {
openFile: () => ipcRenderer.invoke('dialog:openFile')
})
```
:::caution Security warning
We don't directly expose the whole `ipcRenderer.invoke` API for [security reasons]. Make sure to
limit the renderer's access to Electron APIs as much as possible.
:::
### 3. Build the renderer process UI
Finally, let's build the HTML file that we load into our BrowserWindow.
```html {10-11} title='index.html'
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<title>Dialog</title>
</head>
<body>
<button type="button" id="btn">Open a File</button>
File path: <strong id="filePath"></strong>
<script src='./renderer.js'></script>
</body>
</html>
```
The UI consists of a single `#btn` button element that will be used to trigger our preload API, and
a `#filePath` element that will be used to display the path of the selected file. Making these
pieces work will take a few lines of code in the renderer process script:
```javascript title='renderer.js (Renderer Process)'
const btn = document.getElementById('btn')
const filePathElement = document.getElementById('filePath')
btn.addEventListener('click', async () => {
const filePath = await window.electronAPI.openFile()
filePathElement.innerText = filePath
})
```
In the above snippet, we listen for clicks on the `#btn` button, and call our
`window.electronAPI.openFile()` API to activate the native Open File dialog. We then display the
selected file path in the `#filePath` element.
### Note: legacy approaches
The `ipcRenderer.invoke` API was added in Electron 7 as a developer-friendly way to tackle two-way
IPC from the renderer process. However, there exist a couple alternative approaches to this IPC
pattern.
:::warning Avoid legacy approaches if possible
We recommend using `ipcRenderer.invoke` whenever possible. The following two-way renderer-to-main
patterns are documented for historical purposes.
:::
:::info
For the following examples, we're calling `ipcRenderer` directly from the preload script to keep
the code samples small.
:::
#### Using `ipcRenderer.send`
The `ipcRenderer.send` API that we used for single-way communication can also be leveraged to
perform two-way communication. This was the recommended way for asynchronous two-way communication
via IPC prior to Electron 7.
```javascript title='preload.js (Preload Script)'
// You can also put expose this code to the renderer
// process with the `contextBridge` API
const { ipcRenderer } = require('electron')
ipcRenderer.on('asynchronous-reply', (_event, arg) => {
console.log(arg) // prints "pong" in the DevTools console
})
ipcRenderer.send('asynchronous-message', 'ping')
```
```javascript title='main.js (Main Process)'
ipcMain.on('asynchronous-message', (event, arg) => {
console.log(arg) // prints "ping" in the Node console
// works like `send`, but returning a message back
// to the renderer that sent the original message
event.reply('asynchronous-reply', 'pong')
})
```
There are a couple downsides to this approach:
* You need to set up a second `ipcRenderer.on` listener to handle the response in the renderer
process. With `invoke`, you get the response value returned as a Promise to the original API call.
* There's no obvious way to pair the `asynchronous-reply` message to the original
`asynchronous-message` one. If you have very frequent messages going back and forth through these
channels, you would need to add additional app code to track each call and response individually.
#### Using `ipcRenderer.sendSync`
The `ipcRenderer.sendSync` API sends a message to the main process and waits _synchronously_ for a
response.
```javascript title='main.js (Main Process)'
const { ipcMain } = require('electron')
ipcMain.on('synchronous-message', (event, arg) => {
console.log(arg) // prints "ping" in the Node console
event.returnValue = 'pong'
})
```
```javascript title='preload.js (Preload Script)'
// You can also put expose this code to the renderer
// process with the `contextBridge` API
const { ipcRenderer } = require('electron')
const result = ipcRenderer.sendSync('synchronous-message', 'ping')
console.log(result) // prints "pong" in the DevTools console
```
The structure of this code is very similar to the `invoke` model, but we recommend
**avoiding this API** for performance reasons. Its synchronous nature means that it'll block the
renderer process until a reply is received.
## Pattern 3: Main to renderer
When sending a message from the main process to a renderer process, you need to specify which
renderer is receiving the message. Messages need to be sent to a renderer process
via its [`WebContents`] instance. This WebContents instance contains a [`send`][webcontents-send] method
that can be used in the same way as `ipcRenderer.send`.
To demonstrate this pattern, we'll be building a number counter controlled by the native operating
system menu.
For this demo, you'll need to add code to your main process, your renderer process, and a preload
script. The full code is below, but we'll be explaining each file individually in the following
sections.
```fiddle docs/fiddles/ipc/pattern-3
```
### 1. Send messages with the `webContents` module
For this demo, we'll need to first build a custom menu in the main process using Electron's `Menu`
module that uses the `webContents.send` API to send an IPC message from the main process to the
target renderer.
```javascript {11-26} title='main.js (Main Process)'
const {app, BrowserWindow, Menu} = require('electron')
const path = require('path')
function createWindow () {
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
const menu = Menu.buildFromTemplate([
{
label: app.name,
submenu: [
{
click: () => mainWindow.webContents.send('update-counter', 1),
label: 'Increment',
},
{
click: () => mainWindow.webContents.send('update-counter', -1),
label: 'Decrement',
}
]
}
])
Menu.setApplicationMenu(menu)
mainWindow.loadFile('index.html')
}
//...
```
For the purposes of the tutorial, it's important to note that the `click` handler
sends a message (either `1` or `-1`) to the renderer process through the `counter` channel.
```javascript
click: () => mainWindow.webContents.send('update-counter', -1)
```
:::info
Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
:::
### 2. Expose `ipcRenderer.on` via preload
Like in the previous renderer-to-main example, we use the `contextBridge` and `ipcRenderer`
modules in the preload script to expose IPC functionality to the renderer process:
```javascript title='preload.js (Preload Script)'
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld('electronAPI', {
onUpdateCounter: (callback) => ipcRenderer.on('update-counter', callback)
})
```
After loading the preload script, your renderer process should have access to the
`window.electronAPI.onUpdateCounter()` listener function.
:::caution Security warning
We don't directly expose the whole `ipcRenderer.on` API for [security reasons]. Make sure to
limit the renderer's access to Electron APIs as much as possible.
:::
:::info
In the case of this minimal example, you can call `ipcRenderer.on` directly in the preload script
rather than exposing it over the context bridge.
```javascript title='preload.js (Preload Script)'
const { ipcRenderer } = require('electron')
window.addEventListener('DOMContentLoaded', () => {
const counter = document.getElementById('counter')
ipcRenderer.on('update-counter', (_event, value) => {
const oldValue = Number(counter.innerText)
const newValue = oldValue + value
counter.innerText = newValue
})
})
```
However, this approach has limited flexibility compared to exposing your preload APIs
over the context bridge, since your listener can't directly interact with your renderer code.
:::
### 3. Build the renderer process UI
To tie it all together, we'll create an interface in the loaded HTML file that contains a
`#counter` element that we'll use to display the values:
```html {10} title='index.html'
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<title>Menu Counter</title>
</head>
<body>
Current value: <strong id="counter">0</strong>
<script src="./renderer.js"></script>
</body>
</html>
```
Finally, to make the values update in the HTML document, we'll add a few lines of DOM manipulation
so that the value of the `#counter` element is updated whenever we fire an `update-counter` event.
```javascript title='renderer.js (Renderer Process)'
const counter = document.getElementById('counter')
window.electronAPI.onUpdateCounter((_event, value) => {
const oldValue = Number(counter.innerText)
const newValue = oldValue + value
counter.innerText = newValue
})
```
In the above code, we're passing in a callback to the `window.electronAPI.onUpdateCounter` function
exposed from our preload script. The second `value` parameter corresponds to the `1` or `-1` we
were passing in from the `webContents.send` call from the native menu.
### Optional: returning a reply
There's no equivalent for `ipcRenderer.invoke` for main-to-renderer IPC. Instead, you can
send a reply back to the main process from within the `ipcRenderer.on` callback.
We can demonstrate this with slight modifications to the code from the previous example. In the
renderer process, use the `event` parameter to send a reply back to the main process through the
`counter-value` channel.
```javascript title='renderer.js (Renderer Process)'
const counter = document.getElementById('counter')
window.electronAPI.onUpdateCounter((event, value) => {
const oldValue = Number(counter.innerText)
const newValue = oldValue + value
counter.innerText = newValue
event.reply('counter-value', newValue)
})
```
In the main process, listen for `counter-value` events and handle them appropriately.
```javascript title='main.js (Main Process)'
//...
ipcMain.on('counter-value', (_event, value) => {
console.log(value) // will print value to Node console
})
//...
```
## Pattern 4: Renderer to renderer
There's no direct way to send messages between renderer processes in Electron using the `ipcMain`
and `ipcRenderer` modules. To achieve this, you have two options:
* Use the main process as a message broker between renderers. This would involve sending a message
from one renderer to the main process, which would forward the message to the other renderer.
* Pass a [MessagePort] from the main process to both renderers. This will allow direct communication
between renderers after the initial setup.
## Object serialization
Electron's IPC implementation uses the HTML standard
[Structured Clone Algorithm][sca] to serialize objects passed between processes, meaning that
only certain types of objects can be passed through IPC channels.
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.

# Inter-Process Communication
Inter-process communication (IPC) is a key part of building feature-rich desktop applications
in Electron. Because the main and renderer processes have different responsibilities in
Electron's process model, IPC is the only way to perform many common tasks, such as calling a
native API from your UI or triggering changes in your web contents from native menus.
## IPC channels
In Electron, processes communicate by passing messages through developer-defined "channels"
with the [`ipcMain`] and [`ipcRenderer`] modules. These channels are
**arbitrary** (you can name them anything you want) and **bidirectional** (you can use the
same channel name for both modules).
In this guide, we'll be going over some fundamental IPC patterns with concrete examples that
you can use as a reference for your app code.
## Understanding context-isolated processes
Before proceeding to implementation details, you should be familiar with the idea of using a
[preload script] to import Node.js and Electron modules in a context-isolated renderer process.
* For a full overview of Electron's process model, you can read the [process model docs].
* For a primer into exposing APIs from your preload script using the `contextBridge` module, check
out the [context isolation tutorial].
## Pattern 1: Renderer to main (one-way)
To fire a one-way IPC message from a renderer process to the main process, you can use the
[`ipcRenderer.send`] API to send a message that is then received by the [`ipcMain.on`] API.
You usually use this pattern to call a main process API from your web contents. We'll demonstrate
this pattern by creating a simple app that can programmatically change its window title.
For this demo, you'll need to add code to your main process, your renderer process, and a preload
script. The full code is below, but we'll be explaining each file individually in the following
sections.
```fiddle docs/fiddles/ipc/pattern-1
```
### 1. Listen for events with `ipcMain.on`
In the main process, set an IPC listener on the `set-title` channel with the `ipcMain.on` API:
```javascript {6-10,22} title='main.js (Main Process)'
const {app, BrowserWindow, ipcMain} = require('electron')
const path = require('path')
//...
function handleSetTitle (event, title) {
const webContents = event.sender
const win = BrowserWindow.fromWebContents(webContents)
win.setTitle(title)
}
function createWindow () {
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
mainWindow.loadFile('index.html')
}
app.whenReady().then(() => {
ipcMain.on('set-title', handleSetTitle)
createWindow()
}
//...
```
The above `handleSetTitle` callback has two parameters: an [IpcMainEvent] structure and a
`title` string. Whenever a message comes through the `set-title` channel, this function will
find the BrowserWindow instance attached to the message sender and use the `win.setTitle`
API on it.
:::info
Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
:::
### 2. Expose `ipcRenderer.send` via preload
To send messages to the listener created above, you can use the `ipcRenderer.send` API.
By default, the renderer process has no Node.js or Electron module access. As an app developer,
you need to choose which APIs to expose from your preload script using the `contextBridge` API.
In your preload script, add the following code, which will expose a global `window.electronAPI`
variable to your renderer process.
```javascript title='preload.js (Preload Script)'
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld('electronAPI', {
setTitle: (title) => ipcRenderer.send('set-title', title)
})
```
At this point, you'll be able to use the `window.electronAPI.setTitle()` function in the renderer
process.
:::caution Security warning
We don't directly expose the whole `ipcRenderer.send` API for [security reasons]. Make sure to
limit the renderer's access to Electron APIs as much as possible.
:::
### 3. Build the renderer process UI
In our BrowserWindow's loaded HTML file, add a basic user interface consisting of a text input
and a button:
```html {11-12} title='index.html'
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<title>Hello World!</title>
</head>
<body>
Title: <input id="title"/>
<button id="btn" type="button">Set</button>
<script src="./renderer.js"></script>
</body>
</html>
```
To make these elements interactive, we'll be adding a few lines of code in the imported
`renderer.js` file that leverages the `window.electronAPI` functionality exposed from the preload
script:
```javascript title='renderer.js (Renderer Process)'
const setButton = document.getElementById('btn')
const titleInput = document.getElementById('title')
setButton.addEventListener('click', () => {
const title = titleInput.value
window.electronAPI.setTitle(title)
});
```
At this point, your demo should be fully functional. Try using the input field and see what happens
to your BrowserWindow title!
## Pattern 2: Renderer to main (two-way)
A common application for two-way IPC is calling a main process module from your renderer process
code and waiting for a result. This can be done by using [`ipcRenderer.invoke`] paired with
[`ipcMain.handle`].
In the following example, we'll be opening a native file dialog from the renderer process and
returning the selected file's path.
For this demo, you'll need to add code to your main process, your renderer process, and a preload
script. The full code is below, but we'll be explaining each file individually in the following
sections.
```fiddle docs/fiddles/ipc/pattern-2
```
### 1. Listen for events with `ipcMain.handle`
In the main process, we'll be creating a `handleFileOpen()` function that calls
`dialog.showOpenDialog` and returns the value of the file path selected by the user. This function
is used as a callback whenever an `ipcRender.invoke` message is sent through the `dialog:openFile`
channel from the renderer process. The return value is then returned as a Promise to the original
`invoke` call.
:::caution A word on error handling
Errors thrown through `handle` in the main process are not transparent as they
are serialized and only the `message` property from the original error is
provided to the renderer process. Please refer to
[#24427](https://github.com/electron/electron/issues/24427) for details.
:::
```javascript {6-13,25} title='main.js (Main Process)'
const { BrowserWindow, dialog, ipcMain } = require('electron')
const path = require('path')
//...
async function handleFileOpen() {
const { canceled, filePaths } = await dialog.showOpenDialog()
if (canceled) {
return
} else {
return filePaths[0]
}
}
function createWindow () {
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
mainWindow.loadFile('index.html')
}
app.whenReady(() => {
ipcMain.handle('dialog:openFile', handleFileOpen)
createWindow()
})
//...
```
:::tip on channel names
The `dialog:` prefix on the IPC channel name has no effect on the code. It only serves
as a namespace that helps with code readability.
:::
:::info
Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
:::
### 2. Expose `ipcRenderer.invoke` via preload
In the preload script, we expose a one-line `openFile` function that calls and returns the value of
`ipcRenderer.invoke('dialog:openFile')`. We'll be using this API in the next step to call the
native dialog from our renderer's user interface.
```javascript title='preload.js (Preload Script)'
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld('electronAPI', {
openFile: () => ipcRenderer.invoke('dialog:openFile')
})
```
:::caution Security warning
We don't directly expose the whole `ipcRenderer.invoke` API for [security reasons]. Make sure to
limit the renderer's access to Electron APIs as much as possible.
:::
### 3. Build the renderer process UI
Finally, let's build the HTML file that we load into our BrowserWindow.
```html {10-11} title='index.html'
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<title>Dialog</title>
</head>
<body>
<button type="button" id="btn">Open a File</button>
File path: <strong id="filePath"></strong>
<script src='./renderer.js'></script>
</body>
</html>
```
The UI consists of a single `#btn` button element that will be used to trigger our preload API, and
a `#filePath` element that will be used to display the path of the selected file. Making these
pieces work will take a few lines of code in the renderer process script:
```javascript title='renderer.js (Renderer Process)'
const btn = document.getElementById('btn')
const filePathElement = document.getElementById('filePath')
btn.addEventListener('click', async () => {
const filePath = await window.electronAPI.openFile()
filePathElement.innerText = filePath
})
```
In the above snippet, we listen for clicks on the `#btn` button, and call our
`window.electronAPI.openFile()` API to activate the native Open File dialog. We then display the
selected file path in the `#filePath` element.
### Note: legacy approaches
The `ipcRenderer.invoke` API was added in Electron 7 as a developer-friendly way to tackle two-way
IPC from the renderer process. However, there exist a couple alternative approaches to this IPC
pattern.
:::warning Avoid legacy approaches if possible
We recommend using `ipcRenderer.invoke` whenever possible. The following two-way renderer-to-main
patterns are documented for historical purposes.
:::
:::info
For the following examples, we're calling `ipcRenderer` directly from the preload script to keep
the code samples small.
:::
#### Using `ipcRenderer.send`
The `ipcRenderer.send` API that we used for single-way communication can also be leveraged to
perform two-way communication. This was the recommended way for asynchronous two-way communication
via IPC prior to Electron 7.
```javascript title='preload.js (Preload Script)'
// You can also put expose this code to the renderer
// process with the `contextBridge` API
const { ipcRenderer } = require('electron')
ipcRenderer.on('asynchronous-reply', (_event, arg) => {
console.log(arg) // prints "pong" in the DevTools console
})
ipcRenderer.send('asynchronous-message', 'ping')
```
```javascript title='main.js (Main Process)'
ipcMain.on('asynchronous-message', (event, arg) => {
console.log(arg) // prints "ping" in the Node console
// works like `send`, but returning a message back
// to the renderer that sent the original message
event.reply('asynchronous-reply', 'pong')
})
```
There are a couple downsides to this approach:
* You need to set up a second `ipcRenderer.on` listener to handle the response in the renderer
process. With `invoke`, you get the response value returned as a Promise to the original API call.
* There's no obvious way to pair the `asynchronous-reply` message to the original
`asynchronous-message` one. If you have very frequent messages going back and forth through these
channels, you would need to add additional app code to track each call and response individually.
#### Using `ipcRenderer.sendSync`
The `ipcRenderer.sendSync` API sends a message to the main process and waits _synchronously_ for a
response.
```javascript title='main.js (Main Process)'
const { ipcMain } = require('electron')
ipcMain.on('synchronous-message', (event, arg) => {
console.log(arg) // prints "ping" in the Node console
event.returnValue = 'pong'
})
```
```javascript title='preload.js (Preload Script)'
// You can also put expose this code to the renderer
// process with the `contextBridge` API
const { ipcRenderer } = require('electron')
const result = ipcRenderer.sendSync('synchronous-message', 'ping')
console.log(result) // prints "pong" in the DevTools console
```
The structure of this code is very similar to the `invoke` model, but we recommend
**avoiding this API** for performance reasons. Its synchronous nature means that it'll block the
renderer process until a reply is received.
## Pattern 3: Main to renderer
When sending a message from the main process to a renderer process, you need to specify which
renderer is receiving the message. Messages need to be sent to a renderer process
via its [`WebContents`] instance. This WebContents instance contains a [`send`][webcontents-send] method
that can be used in the same way as `ipcRenderer.send`.
To demonstrate this pattern, we'll be building a number counter controlled by the native operating
system menu.
For this demo, you'll need to add code to your main process, your renderer process, and a preload
script. The full code is below, but we'll be explaining each file individually in the following
sections.
```fiddle docs/fiddles/ipc/pattern-3
```
### 1. Send messages with the `webContents` module
For this demo, we'll need to first build a custom menu in the main process using Electron's `Menu`
module that uses the `webContents.send` API to send an IPC message from the main process to the
target renderer.
```javascript {11-26} title='main.js (Main Process)'
const {app, BrowserWindow, Menu} = require('electron')
const path = require('path')
function createWindow () {
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
const menu = Menu.buildFromTemplate([
{
label: app.name,
submenu: [
{
click: () => mainWindow.webContents.send('update-counter', 1),
label: 'Increment',
},
{
click: () => mainWindow.webContents.send('update-counter', -1),
label: 'Decrement',
}
]
}
])
Menu.setApplicationMenu(menu)
mainWindow.loadFile('index.html')
}
//...
```
For the purposes of the tutorial, it's important to note that the `click` handler
sends a message (either `1` or `-1`) to the renderer process through the `counter` channel.
```javascript
click: () => mainWindow.webContents.send('update-counter', -1)
```
:::info
Make sure you're loading the `index.html` and `preload.js` entry points for the following steps!
:::
### 2. Expose `ipcRenderer.on` via preload
Like in the previous renderer-to-main example, we use the `contextBridge` and `ipcRenderer`
modules in the preload script to expose IPC functionality to the renderer process:
```javascript title='preload.js (Preload Script)'
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld('electronAPI', {
onUpdateCounter: (callback) => ipcRenderer.on('update-counter', callback)
})
```
After loading the preload script, your renderer process should have access to the
`window.electronAPI.onUpdateCounter()` listener function.
:::caution Security warning
We don't directly expose the whole `ipcRenderer.on` API for [security reasons]. Make sure to
limit the renderer's access to Electron APIs as much as possible.
:::
:::info
In the case of this minimal example, you can call `ipcRenderer.on` directly in the preload script
rather than exposing it over the context bridge.
```javascript title='preload.js (Preload Script)'
const { ipcRenderer } = require('electron')
window.addEventListener('DOMContentLoaded', () => {
const counter = document.getElementById('counter')
ipcRenderer.on('update-counter', (_event, value) => {
const oldValue = Number(counter.innerText)
const newValue = oldValue + value
counter.innerText = newValue
})
})
```
However, this approach has limited flexibility compared to exposing your preload APIs
over the context bridge, since your listener can't directly interact with your renderer code.
:::
### 3. Build the renderer process UI
To tie it all together, we'll create an interface in the loaded HTML file that contains a
`#counter` element that we'll use to display the values:
```html {10} title='index.html'
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<!-- https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP -->
<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self'">
<title>Menu Counter</title>
</head>
<body>
Current value: <strong id="counter">0</strong>
<script src="./renderer.js"></script>
</body>
</html>
```
Finally, to make the values update in the HTML document, we'll add a few lines of DOM manipulation
so that the value of the `#counter` element is updated whenever we fire an `update-counter` event.
```javascript title='renderer.js (Renderer Process)'
const counter = document.getElementById('counter')
window.electronAPI.onUpdateCounter((_event, value) => {
const oldValue = Number(counter.innerText)
const newValue = oldValue + value
counter.innerText = newValue
})
```
In the above code, we're passing in a callback to the `window.electronAPI.onUpdateCounter` function
exposed from our preload script. The second `value` parameter corresponds to the `1` or `-1` we
were passing in from the `webContents.send` call from the native menu.
### Optional: returning a reply
There's no equivalent for `ipcRenderer.invoke` for main-to-renderer IPC. Instead, you can
send a reply back to the main process from within the `ipcRenderer.on` callback.
We can demonstrate this with slight modifications to the code from the previous example. In the
renderer process, use the `event` parameter to send a reply back to the main process through the
`counter-value` channel.
```javascript title='renderer.js (Renderer Process)'
const counter = document.getElementById('counter')
window.electronAPI.onUpdateCounter((event, value) => {
const oldValue = Number(counter.innerText)
const newValue = oldValue + value
counter.innerText = newValue
event.reply('counter-value', newValue)
})
```
In the main process, listen for `counter-value` events and handle them appropriately.
```javascript title='main.js (Main Process)'
//...
ipcMain.on('counter-value', (_event, value) => {
console.log(value) // will print value to Node console
})
//...
```
## Pattern 4: Renderer to renderer
There's no direct way to send messages between renderer processes in Electron using the `ipcMain`
and `ipcRenderer` modules. To achieve this, you have two options:
* Use the main process as a message broker between renderers. This would involve sending a message
from one renderer to the main process, which would forward the message to the other renderer.
* Pass a [MessagePort] from the main process to both renderers. This will allow direct communication
between renderers after the initial setup.
## Object serialization
Electron's IPC implementation uses the HTML standard
[Structured Clone Algorithm][sca] to serialize objects passed between processes, meaning that
only certain types of objects can be passed through IPC channels.
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.

[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.

[Bug]: Blank page on location change / reload if a filesystem asynchronous call was pending
|
### 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.

### 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.

[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.
