# systemPreferences
> Get system preferences.
Process: [Main](../glossary.md#main-process)
```javascript
const { systemPreferences } = require('electron')
console.log(systemPreferences.isDarkMode())
```
## Events
The `systemPreferences` object emits the following events:
### Event: 'accent-color-changed' _Windows_
Returns:
* `event` Event
* `newColor` string - The new RGBA color the user assigned to be their system
accent color.
### Event: 'color-changed' _Windows_
Returns:
* `event` Event
### Event: 'inverted-color-scheme-changed' _Windows_ _Deprecated_
Returns:
* `event` Event
* `invertedColorScheme` boolean - `true` if an inverted color scheme (a high contrast color scheme with light text and dark backgrounds) is being used, `false` otherwise.
**Deprecated:** Should use the new [`updated`](native-theme.md#event-updated) event on the `nativeTheme` module.
### Event: 'high-contrast-color-scheme-changed' _Windows_ _Deprecated_
Returns:
* `event` Event
* `highContrastColorScheme` boolean - `true` if a high contrast theme is being used, `false` otherwise.
**Deprecated:** Should use the new [`updated`](native-theme.md#event-updated) event on the `nativeTheme` module.
## Methods
### `systemPreferences.isDarkMode()` _macOS_ _Windows_ _Deprecated_
Returns `boolean` - Whether the system is in Dark Mode.
**Deprecated:** Should use the new [`nativeTheme.shouldUseDarkColors`](native-theme.md#nativethemeshouldusedarkcolors-readonly) API.
### `systemPreferences.isSwipeTrackingFromScrollEventsEnabled()` _macOS_
Returns `boolean` - Whether the Swipe between pages setting is on.
### `systemPreferences.postNotification(event, userInfo[, deliverImmediately])` _macOS_
* `event` string
* `userInfo` Record<string, any>
* `deliverImmediately` boolean (optional) - `true` to post notifications immediately even when the subscribing app is inactive.
Posts `event` as native notifications of macOS. The `userInfo` is an Object
that contains the user information dictionary sent along with the notification.
### `systemPreferences.postLocalNotification(event, userInfo)` _macOS_
* `event` string
* `userInfo` Record<string, any>
Posts `event` as native notifications of macOS. The `userInfo` is an Object
that contains the user information dictionary sent along with the notification.
### `systemPreferences.postWorkspaceNotification(event, userInfo)` _macOS_
* `event` string
* `userInfo` Record<string, any>
Posts `event` as native notifications of macOS. The `userInfo` is an Object
that contains the user information dictionary sent along with the notification.
### `systemPreferences.subscribeNotification(event, callback)` _macOS_
* `event` string
* `callback` Function
* `event` string
* `userInfo` Record<string, unknown>
* `object` string
Returns `number` - The ID of this subscription
Subscribes to native notifications of macOS, `callback` will be called with
`callback(event, userInfo)` when the corresponding `event` happens. The
`userInfo` is an Object that contains the user information dictionary sent
along with the notification. The `object` is the sender of the notification,
and only supports `NSString` values for now.
The `id` of the subscriber is returned, which can be used to unsubscribe the
`event`.
Under the hood this API subscribes to `NSDistributedNotificationCenter`,
example values of `event` are:
* `AppleInterfaceThemeChangedNotification`
* `AppleAquaColorVariantChanged`
* `AppleColorPreferencesChangedNotification`
* `AppleShowScrollBarsSettingChanged`
### `systemPreferences.subscribeLocalNotification(event, callback)` _macOS_
* `event` string
* `callback` Function
* `event` string
* `userInfo` Record<string, unknown>
* `object` string
Returns `number` - The ID of this subscription
Same as `subscribeNotification`, but uses `NSNotificationCenter` for local defaults.
This is necessary for events such as `NSUserDefaultsDidChangeNotification`.
### `systemPreferences.subscribeWorkspaceNotification(event, callback)` _macOS_
* `event` string
* `callback` Function
* `event` string
* `userInfo` Record<string, unknown>
* `object` string
Returns `number` - The ID of this subscription
Same as `subscribeNotification`, but uses `NSWorkspace.sharedWorkspace.notificationCenter`.
This is necessary for events such as `NSWorkspaceDidActivateApplicationNotification`.
### `systemPreferences.unsubscribeNotification(id)` _macOS_
* `id` Integer
Removes the subscriber with `id`.
### `systemPreferences.unsubscribeLocalNotification(id)` _macOS_
* `id` Integer
Same as `unsubscribeNotification`, but removes the subscriber from `NSNotificationCenter`.
### `systemPreferences.unsubscribeWorkspaceNotification(id)` _macOS_
* `id` Integer
Same as `unsubscribeNotification`, but removes the subscriber from `NSWorkspace.sharedWorkspace.notificationCenter`.
### `systemPreferences.registerDefaults(defaults)` _macOS_
* `defaults` Record<string, string | boolean | number> - a dictionary of (`key: value`) user defaults
Add the specified defaults to your application's `NSUserDefaults`.
### `systemPreferences.getUserDefault<Type extends keyof UserDefaultTypes>(key, type)` _macOS_
* `key` string
* `type` Type - Can be `string`, `boolean`, `integer`, `float`, `double`,
`url`, `array` or `dictionary`.
Returns [`UserDefaultTypes[Type]`](structures/user-default-types.md) - The value of `key` in `NSUserDefaults`.
Some popular `key` and `type`s are:
* `AppleInterfaceStyle`: `string`
* `AppleAquaColorVariant`: `integer`
* `AppleHighlightColor`: `string`
* `AppleShowScrollBars`: `string`
* `NSNavRecentPlaces`: `array`
* `NSPreferredWebServices`: `dictionary`
* `NSUserDictionaryReplacementItems`: `array`
### `systemPreferences.setUserDefault<Type extends keyof UserDefaultTypes>(key, type, value)` _macOS_
* `key` string
* `type` Type - Can be `string`, `boolean`, `integer`, `float`, `double`, `url`, `array` or `dictionary`.
* `value` UserDefaultTypes[Type]
Set the value of `key` in `NSUserDefaults`.
Note that `type` should match actual type of `value`. An exception is thrown
if they don't.
Some popular `key` and `type`s are:
* `ApplePressAndHoldEnabled`: `boolean`
### `systemPreferences.removeUserDefault(key)` _macOS_
* `key` string
Removes the `key` in `NSUserDefaults`. This can be used to restore the default
or global value of a `key` previously set with `setUserDefault`.
### `systemPreferences.isAeroGlassEnabled()` _Windows_
Returns `boolean` - `true` if [DWM composition][dwm-composition] (Aero Glass) is
enabled, and `false` otherwise.
An example of using it to determine if you should create a transparent window or
not (transparent windows won't work correctly when DWM composition is disabled):
```javascript
const { BrowserWindow, systemPreferences } = require('electron')
const browserOptions = { width: 1000, height: 800 }
// Make the window transparent only if the platform supports it.
if (process.platform !== 'win32' || systemPreferences.isAeroGlassEnabled()) {
browserOptions.transparent = true
browserOptions.frame = false
}
// Create the window.
const win = new BrowserWindow(browserOptions)
// Navigate.
if (browserOptions.transparent) {
win.loadURL(`file://${__dirname}/index.html`)
} else {
// No transparency, so we load a fallback that uses basic styles.
win.loadURL(`file://${__dirname}/fallback.html`)
}
```
[dwm-composition]:https://msdn.microsoft.com/en-us/library/windows/desktop/aa969540.aspx
### `systemPreferences.getAccentColor()` _Windows_ _macOS_
Returns `string` - The users current system wide accent color preference in RGBA
hexadecimal form.
```js
const color = systemPreferences.getAccentColor() // `"aabbccdd"`
const red = color.substr(0, 2) // "aa"
const green = color.substr(2, 2) // "bb"
const blue = color.substr(4, 2) // "cc"
const alpha = color.substr(6, 2) // "dd"
```
This API is only available on macOS 10.14 Mojave or newer.
### `systemPreferences.getColor(color)` _Windows_ _macOS_
* `color` string - One of the following values:

[windows-colors]:https://msdn.microsoft.com/en-us/library/windows/desktop/ms724371(v=vs.85).aspx
[macos-colors]:https://developer.apple.com/design/human-interface-guidelines/macos/visual-design/color#dynamic-system-colors
### `systemPreferences.getSystemColor(color)` _macOS_
* `color` string - One of the following values:
* `blue`
* `brown`
* `gray`
* `green`
* `orange`
* `pink`
* `purple`
* `red`
* `yellow`
Returns `string` - The standard system color formatted as `#RRGGBBAA`.
Returns one of several standard system colors that automatically adapt to vibrancy and changes in accessibility settings like 'Increase contrast' and 'Reduce transparency'. See [Apple Documentation](https://developer.apple.com/design/human-interface-guidelines/macos/visual-design/color#system-colors) for more details.
### `systemPreferences.isInvertedColorScheme()` _Windows_ _Deprecated_
Returns `boolean` - `true` if an inverted color scheme (a high contrast color scheme with light text and dark backgrounds) is active, `false` otherwise.
**Deprecated:** Should use the new [`nativeTheme.shouldUseInvertedColorScheme`](native-theme.md#nativethemeshoulduseinvertedcolorscheme-macos-windows-readonly) API.
### `systemPreferences.isHighContrastColorScheme()` _macOS_ _Windows_ _Deprecated_
Returns `boolean` - `true` if a high contrast theme is active, `false` otherwise.
**Deprecated:** Should use the new [`nativeTheme.shouldUseHighContrastColors`](native-theme.md#nativethemeshouldusehighcontrastcolors-macos-windows-readonly) API.
### `systemPreferences.getEffectiveAppearance()` _macOS_
Returns `string` - Can be `dark`, `light` or `unknown`.
Gets the macOS appearance setting that is currently applied to your application,
maps to [NSApplication.effectiveAppearance](https://developer.apple.com/documentation/appkit/nsapplication/2967171-effectiveappearance?language=objc)
### `systemPreferences.getAppLevelAppearance()` _macOS_ _Deprecated_
Returns `string` | `null` - Can be `dark`, `light` or `unknown`.
Gets the macOS appearance setting that you have declared you want for
your application, maps to [NSApplication.appearance](https://developer.apple.com/documentation/appkit/nsapplication/2967170-appearance?language=objc).
You can use the `setAppLevelAppearance` API to set this value.
### `systemPreferences.setAppLevelAppearance(appearance)` _macOS_ _Deprecated_
* `appearance` string | null - Can be `dark` or `light`
Sets the appearance setting for your application, this should override the
system default and override the value of `getEffectiveAppearance`.
### `systemPreferences.canPromptTouchID()` _macOS_
Returns `boolean` - whether or not this device has the ability to use Touch ID.
**NOTE:** This API will return `false` on macOS systems older than Sierra 10.12.2.
### `systemPreferences.promptTouchID(reason)` _macOS_
* `reason` string - The reason you are asking for Touch ID authentication
Returns `Promise<void>` - resolves if the user has successfully authenticated with Touch ID.
```javascript
const { systemPreferences } = require('electron')
systemPreferences.promptTouchID('To get consent for a Security-Gated Thing').then(success => {
console.log('You have successfully authenticated with Touch ID!')
}).catch(err => {
console.log(err)
})
```
This API itself will not protect your user data; rather, it is a mechanism to allow you to do so. Native apps will need to set [Access Control Constants](https://developer.apple.com/documentation/security/secaccesscontrolcreateflags?language=objc) like [`kSecAccessControlUserPresence`](https://developer.apple.com/documentation/security/secaccesscontrolcreateflags/ksecaccesscontroluserpresence?language=objc) on their keychain entry so that reading it would auto-prompt for Touch ID biometric consent. This could be done with [`node-keytar`](https://github.com/atom/node-keytar), such that one would store an encryption key with `node-keytar` and only fetch it if `promptTouchID()` resolves.
**NOTE:** This API will return a rejected Promise on macOS systems older than Sierra 10.12.2.
### `systemPreferences.isTrustedAccessibilityClient(prompt)` _macOS_
* `prompt` boolean - whether or not the user will be informed via prompt if the current process is untrusted.
Returns `boolean` - `true` if the current process is a trusted accessibility client and `false` if it is not.
### `systemPreferences.getMediaAccessStatus(mediaType)` _Windows_ _macOS_
* `mediaType` string - Can be `microphone`, `camera` or `screen`.
Returns `string` - Can be `not-determined`, `granted`, `denied`, `restricted` or `unknown`.
This user consent was not required on macOS 10.13 High Sierra or lower so this method will always return `granted`.
macOS 10.14 Mojave or higher requires consent for `microphone` and `camera` access.
macOS 10.15 Catalina or higher requires consent for `screen` access.
Windows 10 has a global setting controlling `microphone` and `camera` access for all win32 applications.
It will always return `granted` for `screen` and for all media types on older versions of Windows.
### `systemPreferences.askForMediaAccess(mediaType)` _macOS_
* `mediaType` string - the type of media being requested; can be `microphone`, `camera`.
Returns `Promise<boolean>` - A promise that resolves with `true` if consent was granted and `false` if it was denied. If an invalid `mediaType` is passed, the promise will be rejected. If an access request was denied and later is changed through the System Preferences pane, a restart of the app will be required for the new permissions to take effect. If access has already been requested and denied, it _must_ be changed through the preference pane; an alert will not pop up and the promise will resolve with the existing access status.
**Important:** In order to properly leverage this API, you [must set](https://developer.apple.com/documentation/avfoundation/cameras_and_media_capture/requesting_authorization_for_media_capture_on_macos?language=objc) the `NSMicrophoneUsageDescription` and `NSCameraUsageDescription` strings in your app's `Info.plist` file. The values for these keys will be used to populate the permission dialogs so that the user will be properly informed as to the purpose of the permission request. See [Electron Application Distribution](../tutorial/application-distribution.md#macos) for more information about how to set these in the context of Electron.
This user consent was not required until macOS 10.14 Mojave, so this method will always return `true` if your system is running 10.13 High Sierra or lower.
### `systemPreferences.getAnimationSettings()`
Returns `Object`:
* `shouldRenderRichAnimation` boolean - Returns true if rich animations should be rendered. Looks at session type (e.g. remote desktop) and accessibility settings to give guidance for heavy animations.
* `scrollAnimationsEnabledBySystem` boolean - Determines on a per-platform basis whether scroll animations (e.g. produced by home/end key) should be enabled.
* `prefersReducedMotion` boolean - Determines whether the user desires reduced motion based on platform APIs.
Returns an object with system animation settings.
## Properties
### `systemPreferences.appLevelAppearance` _macOS_
A `string` property that can be `dark`, `light` or `unknown`. It determines the macOS appearance setting for
your application. This maps to values in: [NSApplication.appearance](https://developer.apple.com/documentation/appkit/nsapplication/2967170-appearance?language=objc). Setting this will override the
system default as well as the value of `getEffectiveAppearance`.
Possible values that can be set are `dark` and `light`, and possible return values are `dark`, `light`, and `unknown`.
This property is only available on macOS 10.14 Mojave or newer.
### `systemPreferences.effectiveAppearance` _macOS_ _Readonly_
A `string` property that can be `dark`, `light` or `unknown`.
Returns the macOS appearance setting that is currently applied to your application,
maps to [NSApplication.effectiveAppearance](https://developer.apple.com/documentation/appkit/nsapplication/2967171-effectiveappearance?language=objc)

[Bug]: Name = nil is a valid input for NSDistributedNotificationCenter 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
18
### What operating system are you using?
macOS
### Operating System Version
Mojave
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
https://developer.apple.com/documentation/foundation/nsdistributednotificationcenter/1414136-addobserver
notificationName: _"When nil, the notification center doesn’t use a notification’s name to decide whether to deliver it to the observer."_
Get a running list of all notifications from macOS (no name filter):
```
[com.resilio.Sync.FeOnExtPingAliveNotifiaction]
[com.apple.backup.exclusionschanged]
[com.resilio.Sync.FeOnExtPingAliveNotifiaction]
[com.apple.backup.prefschanged]
[com.resilio.Sync.FeOnExtPingAliveNotifiaction]
[com.resilio.Sync.FeOnExtPingAliveNotifiaction]
[com.resilio.Sync.FeOnExtPingAliveNotifiaction]
```
###
### Actual Behavior
Throws an error.
`> [email protected] start
> electron .
App threw an error during load
TypeError: Error processing argument at index 0, conversion failure from null

### Testcase Gist URL
https://gist.github.com/knev/0cd2a52a0aebe8e35904641df47f60d7
### Additional Information
Electron file: `shell/browser/api/electron_api_system_preferences_mac.mm`
It is obvious that `SysUTF8ToNSString(name)` will throw an error when name is `nil`. `nil` is a valid input.
```
int SystemPreferences::DoSubscribeNotification(
const std::string& name,
const NotificationCallback& callback,
NotificationCenterKind kind) {
int request_id = g_next_id++;
__block NotificationCallback copied_callback = callback;

[Bug]: `ipcRenderer.postMessage` results in `undefined` for `event.senderFrame` in browser process
|
### 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.x
### What operating system are you using?
macOS
### Operating System Version
12.3.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
The `IpcMainEvent.senderFrame` is always defined.
### Actual Behavior
The `IpcMainEvent.senderFrame` is `undefined` when `postMessage` is used.
### Testcase Gist URL
_No response_
### Additional Information
Install a handler in browser process:
```js
ipcMain.on('vscode:postMessage', (event => {
console.log('vscode:postMessage', event.senderFrame);
}));
```
And from the `preload.js` script simply run this code:
```js
ipcRenderer.postMessage('vscode:postMessage', 'message');
```

[Bug]: `ipcRenderer.postMessage` results in `undefined` for `event.senderFrame` in browser process
|
### 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.x
### What operating system are you using?
macOS
### Operating System Version
12.3.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
The `IpcMainEvent.senderFrame` is always defined.
### Actual Behavior
The `IpcMainEvent.senderFrame` is `undefined` when `postMessage` is used.
### Testcase Gist URL
_No response_
### Additional Information
Install a handler in browser process:
```js
ipcMain.on('vscode:postMessage', (event => {
console.log('vscode:postMessage', event.senderFrame);
}));
```
And from the `preload.js` script simply run this code:
```js
ipcRenderer.postMessage('vscode:postMessage', 'message');
```

[Bug]: `ipcRenderer.postMessage` results in `undefined` for `event.senderFrame` in browser process
|
### 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.x
### What operating system are you using?
macOS
### Operating System Version
12.3.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
The `IpcMainEvent.senderFrame` is always defined.
### Actual Behavior
The `IpcMainEvent.senderFrame` is `undefined` when `postMessage` is used.
### Testcase Gist URL
_No response_
### Additional Information
Install a handler in browser process:
```js
ipcMain.on('vscode:postMessage', (event => {
console.log('vscode:postMessage', event.senderFrame);
}));
```
And from the `preload.js` script simply run this code:
```js
ipcRenderer.postMessage('vscode:postMessage', 'message');
```

[Bug]: `ipcRenderer.postMessage` results in `undefined` for `event.senderFrame` in browser process
|
### 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.x
### What operating system are you using?
macOS
### Operating System Version
12.3.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
The `IpcMainEvent.senderFrame` is always defined.
### Actual Behavior
The `IpcMainEvent.senderFrame` is `undefined` when `postMessage` is used.
### Testcase Gist URL
_No response_
### Additional Information
Install a handler in browser process:
```js
ipcMain.on('vscode:postMessage', (event => {
console.log('vscode:postMessage', event.senderFrame);
}));
```
And from the `preload.js` script simply run this code:
```js
ipcRenderer.postMessage('vscode:postMessage', 'message');
```

[Bug]: After entering and exiting Fullscreen, pressing [Esc] no longer works
|
### 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
18.0.3
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
18.0.0
### Expected Behavior
After entering and exiting fullscreen from an iframe and then focusing the parent page, <kbd>Escape</kbd> key events should be delivered to the parent page.
### Actual Behavior
<kbd>Escape</kbd> key events seem not to be delivered to the page after exiting fullscreen.
https://user-images.githubusercontent.com/172800/162848678-c067d18a-e323-49ea-a6b3-f1526149cad1.mp4
### Testcase Gist URL
https://gist.github.com/bc382eeeb368b70fbed1e177bcaacfde
### Additional Information
This only reproduces on Windows, not on macOS.
Also, this only reproduces when _clicking_ the "exit fullscreen" button in the YouTube embed. Pressing <kbd>Esc</kbd> to exit fullscreen allows the parent page to receive subsequent key events.
18.0.0 - not reproducible
18.0.1 - reproducible
18.0.2 - reproducible
18.0.3 - reproducible
This seems likely to be related to https://github.com/electron/electron/pull/32369. cc @codebytere

[Bug]: After entering and exiting Fullscreen, pressing [Esc] no longer works
|
### 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
18.0.3
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
18.0.0
### Expected Behavior
After entering and exiting fullscreen from an iframe and then focusing the parent page, <kbd>Escape</kbd> key events should be delivered to the parent page.
### Actual Behavior
<kbd>Escape</kbd> key events seem not to be delivered to the page after exiting fullscreen.
https://user-images.githubusercontent.com/172800/162848678-c067d18a-e323-49ea-a6b3-f1526149cad1.mp4
### Testcase Gist URL
https://gist.github.com/bc382eeeb368b70fbed1e177bcaacfde
### Additional Information
This only reproduces on Windows, not on macOS.
Also, this only reproduces when _clicking_ the "exit fullscreen" button in the YouTube embed. Pressing <kbd>Esc</kbd> to exit fullscreen allows the parent page to receive subsequent key events.
18.0.0 - not reproducible
18.0.1 - reproducible
18.0.2 - reproducible
18.0.3 - reproducible

[Bug]: clarify in Security document when contextIsolation should be enabled
|
### 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.
### Problem Description
The Security [doc](https://www.electronjs.org/docs/latest/tutorial/security#3-enable-context-isolation-for-remote-content) states:
>Enable Context Isolation for remote content
Based on some of the discussion in [this issue](https://github.com/electron/electron/issues/23506) (specifically [here](https://github.com/electron/electron/issues/23506#issuecomment-922092517)), it sounds like Electron is recommending that we enable `contextIsolation` for *all* content, remote or local.
Should the Sec doc be updated in that case?
### Proposed Solution
Remove the bit about "remote content" from that section
### Alternatives Considered
n/a
### Additional Information
_No response_

An example of exposing an API to a renderer from an isolated preload script is given below:
```javascript
// Preload (Isolated World)
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld(
'electron',
{
doThing: () => ipcRenderer.send('do-a-thing')
}
)
```
```javascript
// Renderer (Main World)
window.electron.doThing()
```
## Glossary
### Main World
The "Main World" is the JavaScript context that your main renderer code runs in. By default, the
page you load in your renderer executes code in this world.
### Isolated World
When `contextIsolation` is enabled in your `webPreferences` (this is the default behavior since Electron 12.0.0), your `preload` scripts run in an
"Isolated World". You can read more about context isolation and what it affects in the
[security](../tutorial/security.md#3-enable-context-isolation-for-remote-content) docs.
## Methods
The `contextBridge` module has the following methods:
### `contextBridge.exposeInMainWorld(apiKey, api)`
* `apiKey` string - The key to inject the API onto `window` with. The API will be accessible on `window[apiKey]`.
* `api` any - Your API, more information on what this API can be and how it works is available below.
## Usage
### API
The `api` provided to [`exposeInMainWorld`](#contextbridgeexposeinmainworldapikey-api) must be a `Function`, `string`, `number`, `Array`, `boolean`, or an object
whose keys are strings and values are a `Function`, `string`, `number`, `Array`, `boolean`, or another nested object that meets the same conditions.
`Function` values are proxied to the other context and all other values are **copied** and **frozen**. Any data / primitives sent in
the API become immutable and updates on either side of the bridge do not result in an update on the other side.
An example of a complex API is shown below:
```javascript
const { contextBridge } = require('electron')
contextBridge.exposeInMainWorld(
'electron',
{
doThing: () => ipcRenderer.send('do-a-thing'),
myPromises: [Promise.resolve(), Promise.reject(new Error('whoops'))],
anAsyncFunction: async () => 123,
data: {
myFlags: ['a', 'b', 'c'],
bootTime: 1234
},
nestedAPI: {
evenDeeper: {
youCanDoThisAsMuchAsYouWant: {
fn: () => ({
returnData: 123
})
}
}
}
}
)
```
### API Functions
`Function` values that you bind through the `contextBridge` are proxied through Electron to ensure that contexts remain isolated. This
results in some key limitations that we've outlined below.
#### Parameter / Error / Return Type support
Because parameters, errors and return values are **copied** when they are sent over the bridge, there are only certain types that can be used.
At a high level, if the type you want to use can be serialized and deserialized into the same object it will work. A table of type support
has been included below for completeness:
| Type | Complexity | Parameter Support | Return Value Support | Limitations |
| ---- | ---------- | ----------------- | -------------------- | ----------- |
| `string` | Simple | ✅ | ✅ | N/A |
| `number` | Simple | ✅ | ✅ | N/A |
| `boolean` | Simple | ✅ | ✅ | N/A |
| `Object` | Complex | ✅ | ✅ | Keys must be supported using only "Simple" types in this table. Values must be supported in this table. Prototype modifications are dropped. Sending custom classes will copy values but not the prototype. |
| `Array` | Complex | ✅ | ✅ | Same limitations as the `Object` type |
| `Error` | Complex | ✅ | ✅ | Errors that are thrown are also copied, this can result in the message and stack trace of the error changing slightly due to being thrown in a different context, and any custom properties on the Error object [will be lost](https://github.com/electron/electron/issues/25596) |
| `Promise` | Complex | ✅ | ✅ | N/A
| `Function` | Complex | ✅ | ✅ | Prototype modifications are dropped. Sending classes or constructors will not work. |
| [Cloneable Types](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm) | Simple | ✅ | ✅ | See the linked document on cloneable types |
| `Element` | Complex | ✅ | ✅ | Prototype modifications are dropped. Sending custom elements will not work. |
| `Blob` | Complex | ✅ | ✅ | N/A |
| `Symbol` | N/A | ❌ | ❌ | Symbols cannot be copied across contexts so they are dropped |
If the type you care about is not in the above table, it is probably not supported.
### Exposing Node Global Symbols
The `contextBridge` can be used by the preload script to give your renderer access to Node APIs.
The table of supported types described above also applies to Node APIs that you expose through `contextBridge`.
Please note that many Node APIs grant access to local system resources.
Be very cautious about which globals and APIs you expose to untrusted remote content.
```javascript
const { contextBridge } = require('electron')
const crypto = require('crypto')
contextBridge.exposeInMainWorld('nodeCrypto', {
sha256sum (data) {
const hash = crypto.createHash('sha256')
hash.update(data)
return hash.digest('hex')
}
})
```

### 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.
### Problem Description
The Security [doc](https://www.electronjs.org/docs/latest/tutorial/security#3-enable-context-isolation-for-remote-content) states:
>Enable Context Isolation for remote content
Based on some of the discussion in [this issue](https://github.com/electron/electron/issues/23506) (specifically [here](https://github.com/electron/electron/issues/23506#issuecomment-922092517)), it sounds like Electron is recommending that we enable `contextIsolation` for *all* content, remote or local.
Should the Sec doc be updated in that case?
### Proposed Solution
Remove the bit about "remote content" from that section
### Alternatives Considered
n/a

# Breaking Changes
Breaking changes will be documented here, and deprecation warnings added to JS code where possible, at least [one major version](tutorial/electron-versioning.md#semver) before the change is made.
### Types of Breaking Changes
This document uses the following convention to categorize breaking changes:
* **API Changed:** An API was changed in such a way that code that has not been updated is guaranteed to throw an exception.
* **Behavior Changed:** The behavior of Electron has changed, but not in such a way that an exception will necessarily be thrown.
* **Default Changed:** Code depending on the old default may break, not necessarily throwing an exception. The old behavior can be restored by explicitly specifying the value.
* **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
* **Removed:** An API or feature was removed, and is no longer supported by Electron.
## Planned Breaking API Changes (20.0)
### Default Changed: renderers without `nodeIntegration: true` are sandboxed by default
Previously, renderers that specified a preload script defaulted to being
unsandboxed. This meant that by default, preload scripts had access to Node.js.
In Electron 20, this default has changed. Beginning in Electron 20, renderers
will be sandboxed by default, unless `nodeIntegration: true` or `sandbox: false`
is specified.
If your preload scripts do not depend on Node, no action is needed. If your
preload scripts _do_ depend on Node, either refactor them to remove Node usage
from the renderer, or explicitly specify `sandbox: false` for the relevant
renderers.
### Removed: `skipTaskbar` on Linux
On X11, `skipTaskbar` sends a `_NET_WM_STATE_SKIP_TASKBAR` message to the X11
window manager. There is not a direct equivalent for Wayland, and the known
workarounds have unacceptable tradeoffs (e.g. Window.is_skip_taskbar in GNOME
requires unsafe mode), so Electron is unable to support this feature on Linux.
## Planned Breaking API Changes (19.0)
None
## Planned Breaking API Changes (18.0)
### Removed: `nativeWindowOpen`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
Since Electron 15, `nativeWindowOpen` has been enabled by default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (17.0)
### Removed: `desktopCapturer.getSources` in the renderer
The `desktopCapturer.getSources` API is now only available in the main process.
This has been changed in order to improve the default security of Electron
apps.
If you need this functionality, it can be replaced as follows:
```js
// Main process
const { ipcMain, desktopCapturer } = require('electron')
ipcMain.handle(
'DESKTOP_CAPTURER_GET_SOURCES',
(event, opts) => desktopCapturer.getSources(opts)
)
```
```js
// Renderer process
const { ipcRenderer } = require('electron')
const desktopCapturer = {
getSources: (opts) => ipcRenderer.invoke('DESKTOP_CAPTURER_GET_SOURCES', opts)
}
```
However, you should consider further restricting the information returned to
the renderer; for instance, displaying a source selector to the user and only
returning the selected source.
### Deprecated: `nativeWindowOpen`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
Since Electron 15, `nativeWindowOpen` has been enabled by default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (16.0)
### Behavior Changed: `crashReporter` implementation switched to Crashpad on Linux
The underlying implementation of the `crashReporter` API on Linux has changed
from Breakpad to Crashpad, bringing it in line with Windows and Mac. As a
result of this, child processes are now automatically monitored, and calling
`process.crashReporter.start` in Node child processes is no longer needed (and
is not advisable, as it will start a second instance of the Crashpad reporter).
There are also some subtle changes to how annotations will be reported on
Linux, including that long values will no longer be split between annotations
appended with `__1`, `__2` and so on, and instead will be truncated at the
(new, longer) annotation value limit.
### Deprecated: `desktopCapturer.getSources` in the renderer
Usage of the `desktopCapturer.getSources` API in the renderer has been
deprecated and will be removed. This change improves the default security of
Electron apps.
See [here](#removed-desktopcapturergetsources-in-the-renderer) for details on
how to replace this API in your app.
## Planned Breaking API Changes (15.0)
### Default Changed: `nativeWindowOpen` defaults to `true`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
`nativeWindowOpen` is no longer experimental, and is now the default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (14.0)
### Removed: `remote` module
The `remote` module was deprecated in Electron 12, and will be removed in
Electron 14. It is replaced by the
[`@electron/remote`](https://github.com/electron/remote) module.
```js
// Deprecated in Electron 12:
const { BrowserWindow } = require('electron').remote
```
```js
// Replace with:
const { BrowserWindow } = require('@electron/remote')
// In the main process:
require('@electron/remote/main').initialize()
```
### Removed: `app.allowRendererProcessReuse`
The `app.allowRendererProcessReuse` property will be removed as part of our plan to
more closely align with Chromium's process model for security, performance and maintainability.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### Removed: Browser Window Affinity
The `affinity` option when constructing a new `BrowserWindow` will be removed
as part of our plan to more closely align with Chromium's process model for security,
performance and maintainability.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### API Changed: `window.open()`
The optional parameter `frameName` will no longer set the title of the window. This now follows the specification described by the [native documentation](https://developer.mozilla.org/en-US/docs/Web/API/Window/open#parameters) under the corresponding parameter `windowName`.
If you were using this parameter to set the title of a window, you can instead use [win.setTitle(title)](api/browser-window.md#winsettitletitle).
### Removed: `worldSafeExecuteJavaScript`
In Electron 14, `worldSafeExecuteJavaScript` will be removed. There is no alternative, please
ensure your code works with this property enabled. It has been enabled by default since Electron
12.
You will be affected by this change if you use either `webFrame.executeJavaScript` or `webFrame.executeJavaScriptInIsolatedWorld`. You will need to ensure that values returned by either of those methods are supported by the [Context Bridge API](api/context-bridge.md#parameter--error--return-type-support) as these methods use the same value passing semantics.
### Removed: BrowserWindowConstructorOptions inheriting from parent windows
Prior to Electron 14, windows opened with `window.open` would inherit
BrowserWindow constructor options such as `transparent` and `resizable` from
their parent window. Beginning with Electron 14, this behavior is removed, and
windows will not inherit any BrowserWindow constructor options from their
parents.
Instead, explicitly set options for the new window with `setWindowOpenHandler`:
```js
webContents.setWindowOpenHandler((details) => {
return {
action: 'allow',
overrideBrowserWindowOptions: {
// ...
}
}
})
```
### Removed: `additionalFeatures`
The deprecated `additionalFeatures` property in the `new-window` and
`did-create-window` events of WebContents has been removed. Since `new-window`
uses positional arguments, the argument is still present, but will always be
the empty array `[]`. (Though note, the `new-window` event itself is
deprecated, and is replaced by `setWindowOpenHandler`.) Bare keys in window
features will now present as keys with the value `true` in the options object.
```js
// Removed in Electron 14
// Triggered by window.open('...', '', 'my-key')
webContents.on('did-create-window', (window, details) => {
if (details.additionalFeatures.includes('my-key')) {
// ...
}
})
// Replace with
webContents.on('did-create-window', (window, details) => {
if (details.options['my-key']) {
// ...
}
})
```
## Planned Breaking API Changes (13.0)
### API Changed: `session.setPermissionCheckHandler(handler)`
The `handler` methods first parameter was previously always a `webContents`, it can now sometimes be `null`. You should use the `requestingOrigin`, `embeddingOrigin` and `securityOrigin` properties to respond to the permission check correctly. As the `webContents` can be `null` it can no longer be relied on.
```js
// Old code
session.setPermissionCheckHandler((webContents, permission) => {
if (webContents.getURL().startsWith('https://google.com/') && permission === 'notification') {
return true
}
return false
})
// Replace with
session.setPermissionCheckHandler((webContents, permission, requestingOrigin) => {
if (new URL(requestingOrigin).hostname === 'google.com' && permission === 'notification') {
return true
}
return false
})
```
### Removed: `shell.moveItemToTrash()`
The deprecated synchronous `shell.moveItemToTrash()` API has been removed. Use
the asynchronous `shell.trashItem()` instead.
```js
// Removed in Electron 13
shell.moveItemToTrash(path)
// Replace with
shell.trashItem(path).then(/* ... */)
```
### Removed: `BrowserWindow` extension APIs
The deprecated extension APIs have been removed:
* `BrowserWindow.addExtension(path)`
* `BrowserWindow.addDevToolsExtension(path)`
* `BrowserWindow.removeExtension(name)`
* `BrowserWindow.removeDevToolsExtension(name)`
* `BrowserWindow.getExtensions()`
* `BrowserWindow.getDevToolsExtensions()`
Use the session APIs instead:
* `ses.loadExtension(path)`
* `ses.removeExtension(extension_id)`
* `ses.getAllExtensions()`
```js
// Removed in Electron 13
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Replace with
session.defaultSession.loadExtension(path)
```
```js
// Removed in Electron 13
BrowserWindow.removeExtension(name)
BrowserWindow.removeDevToolsExtension(name)
// Replace with
session.defaultSession.removeExtension(extension_id)
```
```js
// Removed in Electron 13
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Replace with
session.defaultSession.getAllExtensions()
```
### Removed: methods in `systemPreferences`
The following `systemPreferences` methods have been deprecated:
* `systemPreferences.isDarkMode()`
* `systemPreferences.isInvertedColorScheme()`
* `systemPreferences.isHighContrastColorScheme()`
Use the following `nativeTheme` properties instead:
* `nativeTheme.shouldUseDarkColors`
* `nativeTheme.shouldUseInvertedColorScheme`
* `nativeTheme.shouldUseHighContrastColors`
```js
// Removed in Electron 13
systemPreferences.isDarkMode()
// Replace with
nativeTheme.shouldUseDarkColors
// Removed in Electron 13
systemPreferences.isInvertedColorScheme()
// Replace with
nativeTheme.shouldUseInvertedColorScheme
// Removed in Electron 13
systemPreferences.isHighContrastColorScheme()
// Replace with
nativeTheme.shouldUseHighContrastColors
```
### Deprecated: WebContents `new-window` event
The `new-window` event of WebContents has been deprecated. It is replaced by [`webContents.setWindowOpenHandler()`](api/web-contents.md#contentssetwindowopenhandlerhandler).
```js
// Deprecated in Electron 13
webContents.on('new-window', (event) => {
event.preventDefault()
})
// Replace with
webContents.setWindowOpenHandler((details) => {
return { action: 'deny' }
})
```
## Planned Breaking API Changes (12.0)
### Removed: Pepper Flash support
Chromium has removed support for Flash, and so we must follow suit. See
Chromium's [Flash Roadmap](https://www.chromium.org/flash-roadmap) for more
details.
### Default Changed: `worldSafeExecuteJavaScript` defaults to `true`
In Electron 12, `worldSafeExecuteJavaScript` will be enabled by default. To restore
the previous behavior, `worldSafeExecuteJavaScript: false` must be specified in WebPreferences.
Please note that setting this option to `false` is **insecure**.
This option will be removed in Electron 14 so please migrate your code to support the default
value.
### Default Changed: `contextIsolation` defaults to `true`
In Electron 12, `contextIsolation` will be enabled by default. To restore
the previous behavior, `contextIsolation: false` must be specified in WebPreferences.
We [recommend having contextIsolation enabled](tutorial/security.md#3-enable-context-isolation-for-remote-content) for the security of your application.
Another implication is that `require()` cannot be used in the renderer process unless
`nodeIntegration` is `true` and `contextIsolation` is `false`.
For more details see: https://github.com/electron/electron/issues/23506
### Removed: `crashReporter.getCrashesDirectory()`
The `crashReporter.getCrashesDirectory` method has been removed. Usage
should be replaced by `app.getPath('crashDumps')`.
```js
// Removed in Electron 12
crashReporter.getCrashesDirectory()
// Replace with
app.getPath('crashDumps')
```
### Removed: `crashReporter` methods in the renderer process
The following `crashReporter` methods are no longer available in the renderer
process:
* `crashReporter.start`
* `crashReporter.getLastCrashReport`
* `crashReporter.getUploadedReports`
* `crashReporter.getUploadToServer`
* `crashReporter.setUploadToServer`
* `crashReporter.getCrashesDirectory`
They should be called only from the main process.
See [#23265](https://github.com/electron/electron/pull/23265) for more details.
### Default Changed: `crashReporter.start({ compress: true })`
The default value of the `compress` option to `crashReporter.start` has changed
from `false` to `true`. This means that crash dumps will be uploaded to the
crash ingestion server with the `Content-Encoding: gzip` header, and the body
will be compressed.
If your crash ingestion server does not support compressed payloads, you can
turn off compression by specifying `{ compress: false }` in the crash reporter
options.
### Deprecated: `remote` module
The `remote` module is deprecated in Electron 12, and will be removed in
Electron 14. It is replaced by the
[`@electron/remote`](https://github.com/electron/remote) module.
```js
// Deprecated in Electron 12:
const { BrowserWindow } = require('electron').remote
```
```js
// Replace with:
const { BrowserWindow } = require('@electron/remote')
// In the main process:
require('@electron/remote/main').initialize()
```
### Deprecated: `shell.moveItemToTrash()`
The synchronous `shell.moveItemToTrash()` has been replaced by the new,
asynchronous `shell.trashItem()`.
```js
// Deprecated in Electron 12
shell.moveItemToTrash(path)
// Replace with
shell.trashItem(path).then(/* ... */)
```
## Planned Breaking API Changes (11.0)
### Removed: `BrowserView.{destroy, fromId, fromWebContents, getAllViews}` and `id` property of `BrowserView`
The experimental APIs `BrowserView.{destroy, fromId, fromWebContents, getAllViews}`
have now been removed. Additionally, the `id` property of `BrowserView`
has also been removed.
For more detailed information, see [#23578](https://github.com/electron/electron/pull/23578).
## Planned Breaking API Changes (10.0)
### Deprecated: `companyName` argument to `crashReporter.start()`
The `companyName` argument to `crashReporter.start()`, which was previously
required, is now optional, and further, is deprecated. To get the same
behavior in a non-deprecated way, you can pass a `companyName` value in
`globalExtra`.
```js
// Deprecated in Electron 10
crashReporter.start({ companyName: 'Umbrella Corporation' })
// Replace with
crashReporter.start({ globalExtra: { _companyName: 'Umbrella Corporation' } })
```
### Deprecated: `crashReporter.getCrashesDirectory()`
The `crashReporter.getCrashesDirectory` method has been deprecated. Usage
should be replaced by `app.getPath('crashDumps')`.
```js
// Deprecated in Electron 10
crashReporter.getCrashesDirectory()
// Replace with
app.getPath('crashDumps')
```
### Deprecated: `crashReporter` methods in the renderer process
Calling the following `crashReporter` methods from the renderer process is
deprecated:
* `crashReporter.start`
* `crashReporter.getLastCrashReport`
* `crashReporter.getUploadedReports`
* `crashReporter.getUploadToServer`
* `crashReporter.setUploadToServer`
* `crashReporter.getCrashesDirectory`
The only non-deprecated methods remaining in the `crashReporter` module in the
renderer are `addExtraParameter`, `removeExtraParameter` and `getParameters`.
All above methods remain non-deprecated when called from the main process.
See [#23265](https://github.com/electron/electron/pull/23265) for more details.
### Deprecated: `crashReporter.start({ compress: false })`
Setting `{ compress: false }` in `crashReporter.start` is deprecated. Nearly
all crash ingestion servers support gzip compression. This option will be
removed in a future version of Electron.
### Default Changed: `enableRemoteModule` defaults to `false`
In Electron 9, using the remote module without explicitly enabling it via the
`enableRemoteModule` WebPreferences option began emitting a warning. In
Electron 10, the remote module is now disabled by default. To use the remote
module, `enableRemoteModule: true` must be specified in WebPreferences:
```js
const w = new BrowserWindow({
webPreferences: {
enableRemoteModule: true
}
})
```
We [recommend moving away from the remote
module](https://medium.com/@nornagon/electrons-remote-module-considered-harmful-70d69500f31).
### `protocol.unregisterProtocol`
### `protocol.uninterceptProtocol`
The APIs are now synchronous and the optional callback is no longer needed.
```javascript
// Deprecated
protocol.unregisterProtocol(scheme, () => { /* ... */ })
// Replace with
protocol.unregisterProtocol(scheme)
```
### `protocol.registerFileProtocol`
### `protocol.registerBufferProtocol`
### `protocol.registerStringProtocol`
### `protocol.registerHttpProtocol`
### `protocol.registerStreamProtocol`
### `protocol.interceptFileProtocol`
### `protocol.interceptStringProtocol`
### `protocol.interceptBufferProtocol`
### `protocol.interceptHttpProtocol`
### `protocol.interceptStreamProtocol`
The APIs are now synchronous and the optional callback is no longer needed.
```javascript
// Deprecated
protocol.registerFileProtocol(scheme, handler, () => { /* ... */ })
// Replace with
protocol.registerFileProtocol(scheme, handler)
```
The registered or intercepted protocol does not have effect on current page
until navigation happens.
### `protocol.isProtocolHandled`
This API is deprecated and users should use `protocol.isProtocolRegistered`
and `protocol.isProtocolIntercepted` instead.
```javascript
// Deprecated
protocol.isProtocolHandled(scheme).then(() => { /* ... */ })
// Replace with
const isRegistered = protocol.isProtocolRegistered(scheme)
const isIntercepted = protocol.isProtocolIntercepted(scheme)
```
## Planned Breaking API Changes (9.0)
### Default Changed: Loading non-context-aware native modules in the renderer process is disabled by default
As of Electron 9 we do not allow loading of non-context-aware native modules in
the renderer process. This is to improve security, performance and maintainability
of Electron as a project.
If this impacts you, you can temporarily set `app.allowRendererProcessReuse` to `false`
to revert to the old behavior. This flag will only be an option until Electron 11 so
you should plan to update your native modules to be context aware.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### Deprecated: `BrowserWindow` extension APIs
The following extension APIs have been deprecated:
* `BrowserWindow.addExtension(path)`
* `BrowserWindow.addDevToolsExtension(path)`
* `BrowserWindow.removeExtension(name)`
* `BrowserWindow.removeDevToolsExtension(name)`
* `BrowserWindow.getExtensions()`
* `BrowserWindow.getDevToolsExtensions()`
Use the session APIs instead:
* `ses.loadExtension(path)`
* `ses.removeExtension(extension_id)`
* `ses.getAllExtensions()`
```js
// Deprecated in Electron 9
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Replace with
session.defaultSession.loadExtension(path)
```
```js
// Deprecated in Electron 9
BrowserWindow.removeExtension(name)
BrowserWindow.removeDevToolsExtension(name)
// Replace with
session.defaultSession.removeExtension(extension_id)
```
```js
// Deprecated in Electron 9
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Replace with
session.defaultSession.getAllExtensions()
```
### Removed: `<webview>.getWebContents()`
This API, which was deprecated in Electron 8.0, is now removed.
```js
// Removed in Electron 9.0
webview.getWebContents()
// Replace with
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())
```
### Removed: `webFrame.setLayoutZoomLevelLimits()`
Chromium has removed support for changing the layout zoom level limits, and it
is beyond Electron's capacity to maintain it. The function was deprecated in
Electron 8.x, and has been removed in Electron 9.x. The layout zoom level limits
are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
### Behavior Changed: Sending non-JS objects over IPC now throws an exception
In Electron 8.0, IPC was changed to use the Structured Clone Algorithm,
bringing significant performance improvements. To help ease the transition, the
old IPC serialization algorithm was kept and used for some objects that aren't
serializable with Structured Clone. In particular, DOM objects (e.g. `Element`,
`Location` and `DOMMatrix`), Node.js objects backed by C++ classes (e.g.
`process.env`, some members of `Stream`), and Electron objects backed by C++
classes (e.g. `WebContents`, `BrowserWindow` and `WebFrame`) are not
serializable with Structured Clone. Whenever the old algorithm was invoked, a
deprecation warning was printed.
In Electron 9.0, the old serialization algorithm has been removed, and sending
such non-serializable objects will now throw an "object could not be cloned"
error.
### API Changed: `shell.openItem` is now `shell.openPath`
The `shell.openItem` API has been replaced with an asynchronous `shell.openPath` API.
You can see the original API proposal and reasoning [here](https://github.com/electron/governance/blob/main/wg-api/spec-documents/shell-openitem.md).
## Planned Breaking API Changes (8.0)
### Behavior Changed: Values sent over IPC are now serialized with Structured Clone Algorithm
The algorithm used to serialize objects sent over IPC (through
`ipcRenderer.send`, `ipcRenderer.sendSync`, `WebContents.send` and related
methods) has been switched from a custom algorithm to V8's built-in [Structured
Clone Algorithm][SCA], the same algorithm used to serialize messages for
`postMessage`. This brings about a 2x performance improvement for large
messages, but also brings some breaking changes in behavior.
* Sending Functions, Promises, WeakMaps, WeakSets, or objects containing any
such values, over IPC will now throw an exception, instead of silently
converting the functions to `undefined`.
```js
// Previously:
ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
// => results in { value: 3 } arriving in the main process
// From Electron 8:
ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
// => throws Error("() => {} could not be cloned.")
```
* `NaN`, `Infinity` and `-Infinity` will now be correctly serialized, instead
of being converted to `null`.
* Objects containing cyclic references will now be correctly serialized,
instead of being converted to `null`.
* `Set`, `Map`, `Error` and `RegExp` values will be correctly serialized,
instead of being converted to `{}`.
* `BigInt` values will be correctly serialized, instead of being converted to
`null`.
* Sparse arrays will be serialized as such, instead of being converted to dense
arrays with `null`s.
* `Date` objects will be transferred as `Date` objects, instead of being
converted to their ISO string representation.
* Typed Arrays (such as `Uint8Array`, `Uint16Array`, `Uint32Array` and so on)
will be transferred as such, instead of being converted to Node.js `Buffer`.
* Node.js `Buffer` objects will be transferred as `Uint8Array`s. You can
convert a `Uint8Array` back to a Node.js `Buffer` by wrapping the underlying
`ArrayBuffer`:
```js
Buffer.from(value.buffer, value.byteOffset, value.byteLength)
```
Sending any objects that aren't native JS types, such as DOM objects (e.g.
`Element`, `Location`, `DOMMatrix`), Node.js objects (e.g. `process.env`,
`Stream`), or Electron objects (e.g. `WebContents`, `BrowserWindow`,
`WebFrame`) is deprecated. In Electron 8, these objects will be serialized as
before with a DeprecationWarning message, but starting in Electron 9, sending
these kinds of objects will throw a 'could not be cloned' error.
[SCA]: https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm
### Deprecated: `<webview>.getWebContents()`
This API is implemented using the `remote` module, which has both performance
and security implications. Therefore its usage should be explicit.
```js
// Deprecated
webview.getWebContents()
// Replace with
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())
```
However, it is recommended to avoid using the `remote` module altogether.
```js
// main
const { ipcMain, webContents } = require('electron')
const getGuestForWebContents = (webContentsId, contents) => {
const guest = webContents.fromId(webContentsId)
if (!guest) {
throw new Error(`Invalid webContentsId: ${webContentsId}`)
}
if (guest.hostWebContents !== contents) {
throw new Error('Access denied to webContents')
}
return guest
}
ipcMain.handle('openDevTools', (event, webContentsId) => {
const guest = getGuestForWebContents(webContentsId, event.sender)
guest.openDevTools()
})
// renderer
const { ipcRenderer } = require('electron')
ipcRenderer.invoke('openDevTools', webview.getWebContentsId())
```
### Deprecated: `webFrame.setLayoutZoomLevelLimits()`
Chromium has removed support for changing the layout zoom level limits, and it
is beyond Electron's capacity to maintain it. The function will emit a warning
in Electron 8.x, and cease to exist in Electron 9.x. The layout zoom level
limits are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
### Deprecated events in `systemPreferences`
The following `systemPreferences` events have been deprecated:
* `inverted-color-scheme-changed`
* `high-contrast-color-scheme-changed`
Use the new `updated` event on the `nativeTheme` module instead.
```js
// Deprecated
systemPreferences.on('inverted-color-scheme-changed', () => { /* ... */ })
systemPreferences.on('high-contrast-color-scheme-changed', () => { /* ... */ })
// Replace with
nativeTheme.on('updated', () => { /* ... */ })
```
### Deprecated: methods in `systemPreferences`
The following `systemPreferences` methods have been deprecated:
* `systemPreferences.isDarkMode()`
* `systemPreferences.isInvertedColorScheme()`
* `systemPreferences.isHighContrastColorScheme()`
Use the following `nativeTheme` properties instead:
* `nativeTheme.shouldUseDarkColors`
* `nativeTheme.shouldUseInvertedColorScheme`
* `nativeTheme.shouldUseHighContrastColors`
```js
// Deprecated
systemPreferences.isDarkMode()
// Replace with
nativeTheme.shouldUseDarkColors
// Deprecated
systemPreferences.isInvertedColorScheme()
// Replace with
nativeTheme.shouldUseInvertedColorScheme
// Deprecated
systemPreferences.isHighContrastColorScheme()
// Replace with
nativeTheme.shouldUseHighContrastColors
```
## Planned Breaking API Changes (7.0)
### Deprecated: Atom.io Node Headers URL
This is the URL specified as `disturl` in a `.npmrc` file or as the `--dist-url`
command line flag when building native Node modules. Both will be supported for
the foreseeable future but it is recommended that you switch.
Deprecated: https://atom.io/download/electron
Replace with: https://electronjs.org/headers
### API Changed: `session.clearAuthCache()` no longer accepts options
The `session.clearAuthCache` API no longer accepts options for what to clear, and instead unconditionally clears the whole cache.
```js
// Deprecated
session.clearAuthCache({ type: 'password' })
// Replace with
session.clearAuthCache()
```
### API Changed: `powerMonitor.querySystemIdleState` is now `powerMonitor.getSystemIdleState`
```js
// Removed in Electron 7.0
powerMonitor.querySystemIdleState(threshold, callback)
// Replace with synchronous API
const idleState = powerMonitor.getSystemIdleState(threshold)
```
### API Changed: `powerMonitor.querySystemIdleTime` is now `powerMonitor.getSystemIdleTime`
```js
// Removed in Electron 7.0
powerMonitor.querySystemIdleTime(callback)
// Replace with synchronous API
const idleTime = powerMonitor.getSystemIdleTime()
```
### API Changed: `webFrame.setIsolatedWorldInfo` replaces separate methods
```js
// Removed in Electron 7.0
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)
webFrame.setIsolatedWorldHumanReadableName(worldId, name)
webFrame.setIsolatedWorldSecurityOrigin(worldId, securityOrigin)
// Replace with
webFrame.setIsolatedWorldInfo(
worldId,
{
securityOrigin: 'some_origin',
name: 'human_readable_name',
csp: 'content_security_policy'
})
```
### Removed: `marked` property on `getBlinkMemoryInfo`
This property was removed in Chromium 77, and as such is no longer available.
### Behavior Changed: `webkitdirectory` attribute for `<input type="file"/>` now lists directory contents
The `webkitdirectory` property on HTML file inputs allows them to select folders.
Previous versions of Electron had an incorrect implementation where the `event.target.files`
of the input returned a `FileList` that returned one `File` corresponding to the selected folder.
As of Electron 7, that `FileList` is now list of all files contained within
the folder, similarly to Chrome, Firefox, and Edge
([link to MDN docs](https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/webkitdirectory)).
As an illustration, take a folder with this structure:
```console
folder
├── file1
├── file2
└── file3
```
In Electron <=6, this would return a `FileList` with a `File` object for:
```console
path/to/folder
```
In Electron 7, this now returns a `FileList` with a `File` object for:
```console
/path/to/folder/file3
/path/to/folder/file2
/path/to/folder/file1
```
Note that `webkitdirectory` no longer exposes the path to the selected folder.
If you require the path to the selected folder rather than the folder contents,
see the `dialog.showOpenDialog` API ([link](api/dialog.md#dialogshowopendialogbrowserwindow-options)).
### API Changed: Callback-based versions of promisified APIs
Electron 5 and Electron 6 introduced Promise-based versions of existing
asynchronous APIs and deprecated their older, callback-based counterparts.
In Electron 7, all deprecated callback-based APIs are now removed.
These functions now only return Promises:
* `app.getFileIcon()` [#15742](https://github.com/electron/electron/pull/15742)
* `app.dock.show()` [#16904](https://github.com/electron/electron/pull/16904)

* `shell.openExternal()` [#16176](https://github.com/electron/electron/pull/16176)
* `webContents.loadFile()` [#15855](https://github.com/electron/electron/pull/15855)
* `webContents.loadURL()` [#15855](https://github.com/electron/electron/pull/15855)

* `win.capturePage()` [#15743](https://github.com/electron/electron/pull/15743)
These functions now have two forms, synchronous and Promise-based asynchronous:
* `dialog.showMessageBox()`/`dialog.showMessageBoxSync()` [#17298](https://github.com/electron/electron/pull/17298)
* `dialog.showOpenDialog()`/`dialog.showOpenDialogSync()` [#16973](https://github.com/electron/electron/pull/16973)
* `dialog.showSaveDialog()`/`dialog.showSaveDialogSync()` [#17054](https://github.com/electron/electron/pull/17054)

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

// Replace with
app.releaseSingleInstanceLock()
```
### `app.getGPUInfo`
```js
app.getGPUInfo('complete')
// Now behaves the same with `basic` on macOS
app.getGPUInfo('basic')
```
### `win_delay_load_hook`
When building native modules for windows, the `win_delay_load_hook` variable in
the module's `binding.gyp` must be true (which is the default). If this hook is
not present, then the native module will fail to load on Windows, with an error
message like `Cannot find module`. See the [native module
guide](/docs/tutorial/using-native-node-modules.md) for more.
## Breaking API Changes (3.0)
The following list includes the breaking API changes in Electron 3.0.

command line flag when building native Node modules.
Deprecated: https://atom.io/download/atom-shell
Replace with: https://atom.io/download/electron
## Breaking API Changes (2.0)
The following list includes the breaking API changes made in Electron 2.0.
### `BrowserWindow`
```js
// Deprecated
const optionsA = { titleBarStyle: 'hidden-inset' }
const windowA = new BrowserWindow(optionsA)
// Replace with
const optionsB = { titleBarStyle: 'hiddenInset' }
const windowB = new BrowserWindow(optionsB)
```
### `menu`
```js
// Removed
menu.popup(browserWindow, 100, 200, 2)
// Replaced with
menu.popup(browserWindow, { x: 100, y: 200, positioningItem: 2 })
```
### `nativeImage`
```js
// Removed

nativeImage.toPNG()
// Removed
nativeImage.toJpeg()
// Replaced with

### `process`
* `process.versions.electron` and `process.version.chrome` will be made
read-only properties for consistency with the other `process.versions`
properties set by Node.
### `webContents`
```js
// Removed
webContents.setZoomLevelLimits(1, 2)
// Replaced with
webContents.setVisualZoomLevelLimits(1, 2)

// Replaced with
webview.setVisualZoomLevelLimits(1, 2)
```
### Duplicate ARM Assets
Each Electron release includes two identical ARM builds with slightly different
filenames, like `electron-v1.7.3-linux-arm.zip` and
`electron-v1.7.3-linux-armv7l.zip`. The asset with the `v7l` prefix was added
to clarify to users which ARM version it supports, and to disambiguate it from
future armv6l and arm64 assets that may be produced.
The file _without the prefix_ is still being published to avoid breaking any
setups that may be consuming it. Starting at 2.0, the unprefixed file will
no longer be published.
For details, see
[6986](https://github.com/electron/electron/pull/6986)
and
[7189](https://github.com/electron/electron/pull/7189).

### 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.
### Problem Description
The Security [doc](https://www.electronjs.org/docs/latest/tutorial/security#3-enable-context-isolation-for-remote-content) states:
>Enable Context Isolation for remote content
Based on some of the discussion in [this issue](https://github.com/electron/electron/issues/23506) (specifically [here](https://github.com/electron/electron/issues/23506#issuecomment-922092517)), it sounds like Electron is recommending that we enable `contextIsolation` for *all* content, remote or local.
Should the Sec doc be updated in that case?
### Proposed Solution
Remove the bit about "remote content" from that section
### Alternatives Considered
n/a

## Preface
As web developers, we usually enjoy the strong security net of the browser —
the risks associated with the code we write are relatively small. Our websites
are granted limited powers in a sandbox, and we trust that our users enjoy a
browser built by a large team of engineers that is able to quickly respond to
newly discovered security threats.
When working with Electron, it is important to understand that Electron is not
a web browser. It allows you to build feature-rich desktop applications with
familiar web technologies, but your code wields much greater power. JavaScript
can access the filesystem, user shell, and more. This allows you to build
high quality native applications, but the inherent security risks scale with
the additional powers granted to your code.
With that in mind, be aware that displaying arbitrary content from untrusted
sources poses a severe security risk that Electron is not intended to handle.
In fact, the most popular Electron apps (Atom, Slack, Visual Studio Code, etc)
display primarily local content (or trusted, secure remote content without Node
integration) — if your application executes code from an online source, it is
your responsibility to ensure that the code is not malicious.
## General guidelines
### Security is everyone's responsibility
It is important to remember that the security of your Electron application is
the result of the overall security of the framework foundation
(*Chromium*, *Node.js*), Electron itself, all NPM dependencies and
your code. As such, it is your responsibility to follow a few important best
practices:
* **Keep your application up-to-date with the latest Electron framework release.**
When releasing your product, you’re also shipping a bundle composed of Electron,
Chromium shared library and Node.js. Vulnerabilities affecting these components
may impact the security of your application. By updating Electron to the latest
version, you ensure that critical vulnerabilities (such as *nodeIntegration bypasses*)
are already patched and cannot be exploited in your application. For more information,
see "[Use a current version of Electron](#16-use-a-current-version-of-electron)".
* **Evaluate your dependencies.** While NPM provides half a million reusable packages,
it is your responsibility to choose trusted 3rd-party libraries. If you use outdated
libraries affected by known vulnerabilities or rely on poorly maintained code,
your application security could be in jeopardy.
* **Adopt secure coding practices.** The first line of defense for your application
is your own code. Common web vulnerabilities, such as Cross-Site Scripting (XSS),
have a higher security impact on Electron applications hence it is highly recommended
to adopt secure software development best practices and perform security testing.
### Isolation for untrusted content
A security issue exists whenever you receive code from an untrusted source (e.g.
a remote server) and execute it locally. As an example, consider a remote
website being displayed inside a default [`BrowserWindow`][browser-window]. If
an attacker somehow manages to change said content (either by attacking the
source directly, or by sitting between your app and the actual destination), they
will be able to execute native code on the user's machine.
:::warning
Under no circumstances should you load and execute remote code with
Node.js integration enabled. Instead, use only local files (packaged together
with your application) to execute Node.js code. To display remote content, use
the [`<webview>`][webview-tag] tag or [`BrowserView`][browser-view], make sure
to disable the `nodeIntegration` and enable `contextIsolation`.
:::
:::info Electron security warnings
Security warnings and recommendations are printed to the developer console.
They only show up when the binary's name is Electron, indicating that a developer
is currently looking at the console.
You can force-enable or force-disable these warnings by setting
`ELECTRON_ENABLE_SECURITY_WARNINGS` or `ELECTRON_DISABLE_SECURITY_WARNINGS` on
either `process.env` or the `window` object.
:::

To automate the detection of misconfigurations and insecure patterns, it is
possible to use
[Electronegativity](https://github.com/doyensec/electronegativity). For
additional details on potential weaknesses and implementation bugs when
developing applications using Electron, please refer to this [guide for
developers and auditors](https://doyensec.com/resources/us-17-Carettoni-Electronegativity-A-Study-Of-Electron-Security-wp.pdf).
### 1. Only load secure content
Any resources not included with your application should be loaded using a
secure protocol like `HTTPS`. In other words, do not use insecure protocols
like `HTTP`. Similarly, we recommend the use of `WSS` over `WS`, `FTPS` over
`FTP`, and so on.
#### Why?
`HTTPS` has three main benefits:
1. It authenticates the remote server, ensuring your app connects to the correct
host instead of an impersonator.
1. It ensures data integrity, asserting that the data was not modified while in
transit between your application and the host.
1. It encrypts the traffic between your user and the destination host, making it
more difficult to eavesdrop on the information sent between your app and
the host.
#### How?
```js title='main.js (Main Process)'
// Bad
browserWindow.loadURL('http://example.com')
// Good
browserWindow.loadURL('https://example.com')
```
```html title='index.html (Renderer Process)'
<!-- Bad -->
<script crossorigin src="http://example.com/react.js"></script>
<link rel="stylesheet" href="http://example.com/style.css">
<!-- Good -->
<script crossorigin src="https://example.com/react.js"></script>
<link rel="stylesheet" href="https://example.com/style.css">
```
### 2. Do not enable Node.js integration for remote content
:::info
This recommendation is the default behavior in Electron since 5.0.0.
:::
It is paramount that you do not enable Node.js integration in any renderer
([`BrowserWindow`][browser-window], [`BrowserView`][browser-view], or
[`<webview>`][webview-tag]) that loads remote content. The goal is to limit the
powers you grant to remote content, thus making it dramatically more difficult
for an attacker to harm your users should they gain the ability to execute
JavaScript on your website.
After this, you can grant additional permissions for specific hosts. For example,
if you are opening a BrowserWindow pointed at `https://example.com/`, you can
give that website exactly the abilities it needs, but no more.
#### Why?
A cross-site-scripting (XSS) attack is more dangerous if an attacker can jump
out of the renderer process and execute code on the user's computer.
Cross-site-scripting attacks are fairly common - and while an issue, their
power is usually limited to messing with the website that they are executed on.
Disabling Node.js integration helps prevent an XSS from being escalated into a
so-called "Remote Code Execution" (RCE) attack.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
contextIsolation: false,
nodeIntegration: true,
nodeIntegrationInWorker: true
}
})
mainWindow.loadURL('https://example.com')
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(app.getAppPath(), 'preload.js')
}
})
mainWindow.loadURL('https://example.com')
```
```html title='index.html (Renderer Process)'
<!-- Bad -->
<webview nodeIntegration src="page.html"></webview>
<!-- Good -->
<webview src="page.html"></webview>
```
When disabling Node.js integration, you can still expose APIs to your website that
do consume Node.js modules or features. Preload scripts continue to have access
to `require` and other Node.js features, allowing developers to expose a custom
API to remotely loaded content via the [contextBridge API](../api/context-bridge.md).
### 3. Enable Context Isolation for remote content
:::info
This recommendation is the default behavior in Electron since 12.0.0.
:::
Context isolation is an Electron feature that allows developers to run code
in preload scripts and in Electron APIs in a dedicated JavaScript context. In
practice, that means that global objects like `Array.prototype.push` or
`JSON.parse` cannot be modified by scripts running in the renderer process.
Electron uses the same technology as Chromium's [Content Scripts](https://developer.chrome.com/extensions/content_scripts#execution-environment)
to enable this behavior.
Even when `nodeIntegration: false` is used, to truly enforce strong isolation
and prevent the use of Node primitives `contextIsolation` **must** also be used.
:::info
For more information on what `contextIsolation` is and how to enable it please
see our dedicated [Context Isolation](context-isolation.md) document.
:::info
### 4. Enable process sandboxing
[Sandboxing](https://chromium.googlesource.com/chromium/src/+/HEAD/docs/design/sandbox.md)
is a Chromium feature that uses the operating system to
significantly limit what renderer processes have access to. You should enable
the sandbox in all renderers. Loading, reading or processing any untrusted
content in an unsandboxed process, including the main process, is not advised.
:::info
For more information on what `contextIsolation` is and how to enable it please
see our dedicated [Process Sandboxing](sandbox.md) document.
:::info
### 5. Handle session permission requests from remote content
You may have seen permission requests while using Chrome: they pop up whenever
the website attempts to use a feature that the user has to manually approve (
like notifications).
The API is based on the [Chromium permissions API](https://developer.chrome.com/extensions/permissions)
and implements the same types of permissions.
#### Why?
By default, Electron will automatically approve all permission requests unless
the developer has manually configured a custom handler. While a solid default,
security-conscious developers might want to assume the very opposite.
#### How?
```js title='main.js (Main Process)'
const { session } = require('electron')
const URL = require('url').URL
session
.fromPartition('some-partition')
.setPermissionRequestHandler((webContents, permission, callback) => {
const parsedUrl = new URL(webContents.getURL())
if (permission === 'notifications') {
// Approves the permissions request
callback(true)
}
// Verify URL
if (parsedUrl.protocol !== 'https:' || parsedUrl.host !== 'example.com') {
// Denies the permissions request
return callback(false)
}
})
```
### 6. Do not disable `webSecurity`
:::info
This recommendation is Electron's default.
:::
You may have already guessed that disabling the `webSecurity` property on a
renderer process ([`BrowserWindow`][browser-window],
[`BrowserView`][browser-view], or [`<webview>`][webview-tag]) disables crucial
security features.
Do not disable `webSecurity` in production applications.
#### Why?
Disabling `webSecurity` will disable the same-origin policy and set
`allowRunningInsecureContent` property to `true`. In other words, it allows
the execution of insecure code from different domains.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
webSecurity: false
}
})
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow()
```
```html title='index.html (Renderer Process)'
<!-- Bad -->
<webview disablewebsecurity src="page.html"></webview>
<!-- Good -->
<webview src="page.html"></webview>
```
### 7. Define a Content Security Policy
A Content Security Policy (CSP) is an additional layer of protection against
cross-site-scripting attacks and data injection attacks. We recommend that they
be enabled by any website you load inside Electron.
#### Why?
CSP allows the server serving content to restrict and control the resources
Electron can load for that given web page. `https://example.com` should
be allowed to load scripts from the origins you defined while scripts from
`https://evil.attacker.com` should not be allowed to run. Defining a CSP is an
easy way to improve your application's security.
#### How?
The following CSP will allow Electron to execute scripts from the current
website and from `apis.example.com`.
```plaintext
// Bad
Content-Security-Policy: '*'
// Good
Content-Security-Policy: script-src 'self' https://apis.example.com
```
#### CSP HTTP headers
Electron respects the [`Content-Security-Policy` HTTP header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy)
which can be set using Electron's
[`webRequest.onHeadersReceived`](../api/web-request.md#webrequestonheadersreceivedfilter-listener)
handler:
```javascript title='main.js (Main Process)'
const { session } = require('electron')
session.defaultSession.webRequest.onHeadersReceived((details, callback) => {
callback({
responseHeaders: {
...details.responseHeaders,
'Content-Security-Policy': ['default-src \'none\'']
}
})
})
```
#### CSP meta tag
CSP's preferred delivery mechanism is an HTTP header. However, it is not possible
to use this method when loading a resource using the `file://` protocol. It can
be useful in some cases to set a policy on a page directly in the markup using a
`<meta>` tag:
```html title='index.html (Renderer Process)'
<meta http-equiv="Content-Security-Policy" content="default-src 'none'">
```
### 8. Do not enable `allowRunningInsecureContent`
:::info
This recommendation is Electron's default.
:::
By default, Electron will not allow websites loaded over `HTTPS` to load and
execute scripts, CSS, or plugins from insecure sources (`HTTP`). Setting the
property `allowRunningInsecureContent` to `true` disables that protection.
Loading the initial HTML of a website over `HTTPS` and attempting to load
subsequent resources via `HTTP` is also known as "mixed content".
#### Why?
Loading content over `HTTPS` assures the authenticity and integrity
of the loaded resources while encrypting the traffic itself. See the section on
[only displaying secure content](#1-only-load-secure-content) for more details.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
allowRunningInsecureContent: true
}
})
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow({})
```
### 9. Do not enable experimental features
:::info
This recommendation is Electron's default.
:::
Advanced users of Electron can enable experimental Chromium features using the
`experimentalFeatures` property.
#### Why?
Experimental features are, as the name suggests, experimental and have not been
enabled for all Chromium users. Furthermore, their impact on Electron as a whole
has likely not been tested.
Legitimate use cases exist, but unless you know what you are doing, you should
not enable this property.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
experimentalFeatures: true
}
})
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow({})
```
### 10. Do not use `enableBlinkFeatures`
:::info
This recommendation is Electron's default.
:::
Blink is the name of the rendering engine behind Chromium. As with
`experimentalFeatures`, the `enableBlinkFeatures` property allows developers to
enable features that have been disabled by default.
#### Why?
Generally speaking, there are likely good reasons if a feature was not enabled
by default. Legitimate use cases for enabling specific features exist. As a
developer, you should know exactly why you need to enable a feature, what the
ramifications are, and how it impacts the security of your application. Under
no circumstances should you enable features speculatively.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
enableBlinkFeatures: 'ExecCommandInJavaScript'
}
})
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow()
```
### 11. Do not use `allowpopups` for WebViews
:::info
This recommendation is Electron's default.
:::
If you are using [`<webview>`][webview-tag], you might need the pages and scripts
loaded in your `<webview>` tag to open new windows. The `allowpopups` attribute
enables them to create new [`BrowserWindows`][browser-window] using the
`window.open()` method. `<webview>` tags are otherwise not allowed to create new
windows.
#### Why?
If you do not need popups, you are better off not allowing the creation of
new [`BrowserWindows`][browser-window] by default. This follows the principle
of minimally required access: Don't let a website create new popups unless
you know it needs that feature.
#### How?
```html title='index.html (Renderer Process)'
<!-- Bad -->
<webview allowpopups src="page.html"></webview>
<!-- Good -->
<webview src="page.html"></webview>
```
### 12. Verify WebView options before creation
A WebView created in a renderer process that does not have Node.js integration
enabled will not be able to enable integration itself. However, a WebView will
always create an independent renderer process with its own `webPreferences`.
It is a good idea to control the creation of new [`<webview>`][webview-tag] tags
from the main process and to verify that their webPreferences do not disable
security features.
#### Why?
Since `<webview>` live in the DOM, they can be created by a script running on your
website even if Node.js integration is otherwise disabled.
Electron enables developers to disable various security features that control
a renderer process. In most cases, developers do not need to disable any of
those features - and you should therefore not allow different configurations
for newly created [`<webview>`][webview-tag] tags.
#### How?
Before a [`<webview>`][webview-tag] tag is attached, Electron will fire the
`will-attach-webview` event on the hosting `webContents`. Use the event to
prevent the creation of `webViews` with possibly insecure options.
```js title='main.js (Main Process)'
app.on('web-contents-created', (event, contents) => {
contents.on('will-attach-webview', (event, webPreferences, params) => {
// Strip away preload scripts if unused or verify their location is legitimate
delete webPreferences.preload
// Disable Node.js integration
webPreferences.nodeIntegration = false
// Verify URL being loaded
if (!params.src.startsWith('https://example.com/')) {
event.preventDefault()
}
})
})
```
Again, this list merely minimizes the risk, but does not remove it. If your goal
is to display a website, a browser will be a more secure option.
### 13. Disable or limit navigation
If your app has no need to navigate or only needs to navigate to known pages,
it is a good idea to limit navigation outright to that known scope, disallowing
any other kinds of navigation.
#### Why?
Navigation is a common attack vector. If an attacker can convince your app to
navigate away from its current page, they can possibly force your app to open
web sites on the Internet. Even if your `webContents` are configured to be more
secure (like having `nodeIntegration` disabled or `contextIsolation` enabled),
getting your app to open a random web site will make the work of exploiting your
app a lot easier.
A common attack pattern is that the attacker convinces your app's users to
interact with the app in such a way that it navigates to one of the attacker's
pages. This is usually done via links, plugins, or other user-generated content.
#### How?
If your app has no need for navigation, you can call `event.preventDefault()`
in a [`will-navigate`][will-navigate] handler. If you know which pages your app
might navigate to, check the URL in the event handler and only let navigation
occur if it matches the URLs you're expecting.
We recommend that you use Node's parser for URLs. Simple string comparisons can
sometimes be fooled - a `startsWith('https://example.com')` test would let
`https://example.com.attacker.com` through.
```js title='main.js (Main Process)'
const URL = require('url').URL
app.on('web-contents-created', (event, contents) => {
contents.on('will-navigate', (event, navigationUrl) => {
const parsedUrl = new URL(navigationUrl)
if (parsedUrl.origin !== 'https://example.com') {
event.preventDefault()
}
})
})
```
### 14. Disable or limit creation of new windows
If you have a known set of windows, it's a good idea to limit the creation of
additional windows in your app.
#### Why?
Much like navigation, the creation of new `webContents` is a common attack
vector. Attackers attempt to convince your app to create new windows, frames,
or other renderer processes with more privileges than they had before; or
with pages opened that they couldn't open before.
If you have no need to create windows in addition to the ones you know you'll
need to create, disabling the creation buys you a little bit of extra
security at no cost. This is commonly the case for apps that open one
`BrowserWindow` and do not need to open an arbitrary number of additional
windows at runtime.
#### How?
[`webContents`][web-contents] will delegate to its [window open
handler][window-open-handler] before creating new windows. The handler will
receive, amongst other parameters, the `url` the window was requested to open
and the options used to create it. We recommend that you register a handler to
monitor the creation of windows, and deny any unexpected window creation.
```js title='main.js (Main Process)'
const { shell } = require('electron')
app.on('web-contents-created', (event, contents) => {
contents.setWindowOpenHandler(({ url }) => {
// In this example, we'll ask the operating system
// to open this event's url in the default browser.
//
// See the following item for considerations regarding what
// URLs should be allowed through to shell.openExternal.
if (isSafeForExternalOpen(url)) {
setImmediate(() => {
shell.openExternal(url)
})
}
return { action: 'deny' }
})
})
```
### 15. Do not use `shell.openExternal` with untrusted content
The shell module's [`openExternal`][open-external] API allows opening a given
protocol URI with the desktop's native utilities. On macOS, for instance, this
function is similar to the `open` terminal command utility and will open the
specific application based on the URI and filetype association.
#### Why?
Improper use of [`openExternal`][open-external] can be leveraged to compromise
the user's host. When openExternal is used with untrusted content, it can be
leveraged to execute arbitrary commands.
#### How?
```js title='main.js (Main Process)'
// Bad
const { shell } = require('electron')
shell.openExternal(USER_CONTROLLED_DATA_HERE)
```
```js title='main.js (Main Process)'
// Good
const { shell } = require('electron')
shell.openExternal('https://example.com/index.html')
```
### 16. Use a current version of Electron
You should strive for always using the latest available version of Electron.
Whenever a new major version is released, you should attempt to update your
app as quickly as possible.
#### Why?
An application built with an older version of Electron, Chromium, and Node.js
is an easier target than an application that is using more recent versions of
those components. Generally speaking, security issues and exploits for older
versions of Chromium and Node.js are more widely available.
Both Chromium and Node.js are impressive feats of engineering built by
thousands of talented developers. Given their popularity, their security is
carefully tested and analyzed by equally skilled security researchers. Many of
those researchers [disclose vulnerabilities responsibly][responsible-disclosure],
which generally means that researchers will give Chromium and Node.js some time
to fix issues before publishing them. Your application will be more secure if
it is running a recent version of Electron (and thus, Chromium and Node.js) for
which potential security issues are not as widely known.
#### How?
Migrate your app one major version at a time, while referring to Electron's
[Breaking Changes][breaking-changes] document to see if any code needs to
be updated.
### 17. Validate the `sender` of all IPC messages
You should always validate incoming IPC messages `sender` property to ensure you
aren't performing actions or sending information to untrusted renderers.
#### Why?
All Web Frames can in theory send IPC messages to the main process, including
iframes and child windows in some scenarios. If you have an IPC message that returns
user data to the sender via `event.reply` or performs privileged actions that the renderer
can't natively, you should ensure you aren't listening to third party web frames.
You should be validating the `sender` of **all** IPC messages by default.
#### How?
```js title='main.js (Main Process)'
// Bad
ipcMain.handle('get-secrets', () => {
return getSecrets();
});
// Good
ipcMain.handle('get-secrets', (e) => {
if (!validateSender(e.senderFrame)) return null;
return getSecrets();
});
function validateSender(frame) {
// Value the host of the URL using an actual URL parser and an allowlist
if ((new URL(frame.url)).host === 'electronjs.org') return true;
return false;
}
```

### 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.
### Problem Description
The Security [doc](https://www.electronjs.org/docs/latest/tutorial/security#3-enable-context-isolation-for-remote-content) states:
>Enable Context Isolation for remote content
Based on some of the discussion in [this issue](https://github.com/electron/electron/issues/23506) (specifically [here](https://github.com/electron/electron/issues/23506#issuecomment-922092517)), it sounds like Electron is recommending that we enable `contextIsolation` for *all* content, remote or local.
Should the Sec doc be updated in that case?
### Proposed Solution
Remove the bit about "remote content" from that section
### Alternatives Considered

# contextBridge
> Create a safe, bi-directional, synchronous bridge across isolated contexts
Process: [Renderer](../glossary.md#renderer-process)
An example of exposing an API to a renderer from an isolated preload script is given below:
```javascript
// Preload (Isolated World)
const { contextBridge, ipcRenderer } = require('electron')
contextBridge.exposeInMainWorld(
'electron',
{
doThing: () => ipcRenderer.send('do-a-thing')
}
)
```
```javascript
// Renderer (Main World)
window.electron.doThing()
```
## Glossary
### Main World
The "Main World" is the JavaScript context that your main renderer code runs in. By default, the
page you load in your renderer executes code in this world.
### Isolated World
When `contextIsolation` is enabled in your `webPreferences` (this is the default behavior since Electron 12.0.0), your `preload` scripts run in an
"Isolated World". You can read more about context isolation and what it affects in the
[security](../tutorial/security.md#3-enable-context-isolation-for-remote-content) docs.
## Methods
The `contextBridge` module has the following methods:
### `contextBridge.exposeInMainWorld(apiKey, api)`
* `apiKey` string - The key to inject the API onto `window` with. The API will be accessible on `window[apiKey]`.
* `api` any - Your API, more information on what this API can be and how it works is available below.
## Usage
### API
The `api` provided to [`exposeInMainWorld`](#contextbridgeexposeinmainworldapikey-api) must be a `Function`, `string`, `number`, `Array`, `boolean`, or an object
whose keys are strings and values are a `Function`, `string`, `number`, `Array`, `boolean`, or another nested object that meets the same conditions.
`Function` values are proxied to the other context and all other values are **copied** and **frozen**. Any data / primitives sent in
the API become immutable and updates on either side of the bridge do not result in an update on the other side.
An example of a complex API is shown below:
```javascript
const { contextBridge } = require('electron')
contextBridge.exposeInMainWorld(
'electron',
{
doThing: () => ipcRenderer.send('do-a-thing'),
myPromises: [Promise.resolve(), Promise.reject(new Error('whoops'))],
anAsyncFunction: async () => 123,
data: {
myFlags: ['a', 'b', 'c'],
bootTime: 1234
},
nestedAPI: {
evenDeeper: {
youCanDoThisAsMuchAsYouWant: {
fn: () => ({
returnData: 123
})
}
}
}
}
)
```
### API Functions
`Function` values that you bind through the `contextBridge` are proxied through Electron to ensure that contexts remain isolated. This
results in some key limitations that we've outlined below.
#### Parameter / Error / Return Type support
Because parameters, errors and return values are **copied** when they are sent over the bridge, there are only certain types that can be used.
At a high level, if the type you want to use can be serialized and deserialized into the same object it will work. A table of type support
has been included below for completeness:
| Type | Complexity | Parameter Support | Return Value Support | Limitations |
| ---- | ---------- | ----------------- | -------------------- | ----------- |
| `string` | Simple | ✅ | ✅ | N/A |
| `number` | Simple | ✅ | ✅ | N/A |
| `boolean` | Simple | ✅ | ✅ | N/A |
| `Object` | Complex | ✅ | ✅ | Keys must be supported using only "Simple" types in this table. Values must be supported in this table. Prototype modifications are dropped. Sending custom classes will copy values but not the prototype. |
| `Array` | Complex | ✅ | ✅ | Same limitations as the `Object` type |
| `Error` | Complex | ✅ | ✅ | Errors that are thrown are also copied, this can result in the message and stack trace of the error changing slightly due to being thrown in a different context, and any custom properties on the Error object [will be lost](https://github.com/electron/electron/issues/25596) |
| `Promise` | Complex | ✅ | ✅ | N/A
| `Function` | Complex | ✅ | ✅ | Prototype modifications are dropped. Sending classes or constructors will not work. |
| [Cloneable Types](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm) | Simple | ✅ | ✅ | See the linked document on cloneable types |
| `Element` | Complex | ✅ | ✅ | Prototype modifications are dropped. Sending custom elements will not work. |
| `Blob` | Complex | ✅ | ✅ | N/A |
| `Symbol` | N/A | ❌ | ❌ | Symbols cannot be copied across contexts so they are dropped |
If the type you care about is not in the above table, it is probably not supported.
### Exposing Node Global Symbols
The `contextBridge` can be used by the preload script to give your renderer access to Node APIs.
The table of supported types described above also applies to Node APIs that you expose through `contextBridge`.
Please note that many Node APIs grant access to local system resources.
Be very cautious about which globals and APIs you expose to untrusted remote content.
```javascript
const { contextBridge } = require('electron')
const crypto = require('crypto')
contextBridge.exposeInMainWorld('nodeCrypto', {
sha256sum (data) {
const hash = crypto.createHash('sha256')
hash.update(data)
return hash.digest('hex')
}
})
```

### 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.
### Problem Description
The Security [doc](https://www.electronjs.org/docs/latest/tutorial/security#3-enable-context-isolation-for-remote-content) states:
>Enable Context Isolation for remote content
Based on some of the discussion in [this issue](https://github.com/electron/electron/issues/23506) (specifically [here](https://github.com/electron/electron/issues/23506#issuecomment-922092517)), it sounds like Electron is recommending that we enable `contextIsolation` for *all* content, remote or local.
Should the Sec doc be updated in that case?
### Proposed Solution
Remove the bit about "remote content" from that section
### Alternatives Considered
n/a

# Breaking Changes
Breaking changes will be documented here, and deprecation warnings added to JS code where possible, at least [one major version](tutorial/electron-versioning.md#semver) before the change is made.
### Types of Breaking Changes
This document uses the following convention to categorize breaking changes:
* **API Changed:** An API was changed in such a way that code that has not been updated is guaranteed to throw an exception.
* **Behavior Changed:** The behavior of Electron has changed, but not in such a way that an exception will necessarily be thrown.
* **Default Changed:** Code depending on the old default may break, not necessarily throwing an exception. The old behavior can be restored by explicitly specifying the value.
* **Deprecated:** An API was marked as deprecated. The API will continue to function, but will emit a deprecation warning, and will be removed in a future release.
* **Removed:** An API or feature was removed, and is no longer supported by Electron.
## Planned Breaking API Changes (20.0)
### Default Changed: renderers without `nodeIntegration: true` are sandboxed by default
Previously, renderers that specified a preload script defaulted to being
unsandboxed. This meant that by default, preload scripts had access to Node.js.
In Electron 20, this default has changed. Beginning in Electron 20, renderers
will be sandboxed by default, unless `nodeIntegration: true` or `sandbox: false`
is specified.
If your preload scripts do not depend on Node, no action is needed. If your
preload scripts _do_ depend on Node, either refactor them to remove Node usage
from the renderer, or explicitly specify `sandbox: false` for the relevant
renderers.
### Removed: `skipTaskbar` on Linux
On X11, `skipTaskbar` sends a `_NET_WM_STATE_SKIP_TASKBAR` message to the X11
window manager. There is not a direct equivalent for Wayland, and the known
workarounds have unacceptable tradeoffs (e.g. Window.is_skip_taskbar in GNOME
requires unsafe mode), so Electron is unable to support this feature on Linux.
## Planned Breaking API Changes (19.0)
None
## Planned Breaking API Changes (18.0)
### Removed: `nativeWindowOpen`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
Since Electron 15, `nativeWindowOpen` has been enabled by default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (17.0)
### Removed: `desktopCapturer.getSources` in the renderer
The `desktopCapturer.getSources` API is now only available in the main process.
This has been changed in order to improve the default security of Electron
apps.
If you need this functionality, it can be replaced as follows:
```js
// Main process
const { ipcMain, desktopCapturer } = require('electron')
ipcMain.handle(
'DESKTOP_CAPTURER_GET_SOURCES',
(event, opts) => desktopCapturer.getSources(opts)
)
```
```js
// Renderer process
const { ipcRenderer } = require('electron')
const desktopCapturer = {
getSources: (opts) => ipcRenderer.invoke('DESKTOP_CAPTURER_GET_SOURCES', opts)
}
```
However, you should consider further restricting the information returned to
the renderer; for instance, displaying a source selector to the user and only
returning the selected source.
### Deprecated: `nativeWindowOpen`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
Since Electron 15, `nativeWindowOpen` has been enabled by default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (16.0)
### Behavior Changed: `crashReporter` implementation switched to Crashpad on Linux
The underlying implementation of the `crashReporter` API on Linux has changed
from Breakpad to Crashpad, bringing it in line with Windows and Mac. As a
result of this, child processes are now automatically monitored, and calling
`process.crashReporter.start` in Node child processes is no longer needed (and
is not advisable, as it will start a second instance of the Crashpad reporter).
There are also some subtle changes to how annotations will be reported on
Linux, including that long values will no longer be split between annotations
appended with `__1`, `__2` and so on, and instead will be truncated at the
(new, longer) annotation value limit.
### Deprecated: `desktopCapturer.getSources` in the renderer
Usage of the `desktopCapturer.getSources` API in the renderer has been
deprecated and will be removed. This change improves the default security of
Electron apps.
See [here](#removed-desktopcapturergetsources-in-the-renderer) for details on
how to replace this API in your app.
## Planned Breaking API Changes (15.0)
### Default Changed: `nativeWindowOpen` defaults to `true`
Prior to Electron 15, `window.open` was by default shimmed to use
`BrowserWindowProxy`. This meant that `window.open('about:blank')` did not work
to open synchronously scriptable child windows, among other incompatibilities.
`nativeWindowOpen` is no longer experimental, and is now the default.
See the documentation for [window.open in Electron](api/window-open.md)
for more details.
## Planned Breaking API Changes (14.0)
### Removed: `remote` module
The `remote` module was deprecated in Electron 12, and will be removed in
Electron 14. It is replaced by the
[`@electron/remote`](https://github.com/electron/remote) module.
```js
// Deprecated in Electron 12:
const { BrowserWindow } = require('electron').remote
```
```js
// Replace with:
const { BrowserWindow } = require('@electron/remote')
// In the main process:
require('@electron/remote/main').initialize()
```
### Removed: `app.allowRendererProcessReuse`
The `app.allowRendererProcessReuse` property will be removed as part of our plan to
more closely align with Chromium's process model for security, performance and maintainability.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### Removed: Browser Window Affinity
The `affinity` option when constructing a new `BrowserWindow` will be removed
as part of our plan to more closely align with Chromium's process model for security,
performance and maintainability.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### API Changed: `window.open()`
The optional parameter `frameName` will no longer set the title of the window. This now follows the specification described by the [native documentation](https://developer.mozilla.org/en-US/docs/Web/API/Window/open#parameters) under the corresponding parameter `windowName`.
If you were using this parameter to set the title of a window, you can instead use [win.setTitle(title)](api/browser-window.md#winsettitletitle).
### Removed: `worldSafeExecuteJavaScript`
In Electron 14, `worldSafeExecuteJavaScript` will be removed. There is no alternative, please
ensure your code works with this property enabled. It has been enabled by default since Electron
12.
You will be affected by this change if you use either `webFrame.executeJavaScript` or `webFrame.executeJavaScriptInIsolatedWorld`. You will need to ensure that values returned by either of those methods are supported by the [Context Bridge API](api/context-bridge.md#parameter--error--return-type-support) as these methods use the same value passing semantics.
### Removed: BrowserWindowConstructorOptions inheriting from parent windows
Prior to Electron 14, windows opened with `window.open` would inherit
BrowserWindow constructor options such as `transparent` and `resizable` from
their parent window. Beginning with Electron 14, this behavior is removed, and
windows will not inherit any BrowserWindow constructor options from their
parents.
Instead, explicitly set options for the new window with `setWindowOpenHandler`:
```js
webContents.setWindowOpenHandler((details) => {
return {
action: 'allow',
overrideBrowserWindowOptions: {
// ...
}
}
})
```
### Removed: `additionalFeatures`
The deprecated `additionalFeatures` property in the `new-window` and
`did-create-window` events of WebContents has been removed. Since `new-window`
uses positional arguments, the argument is still present, but will always be
the empty array `[]`. (Though note, the `new-window` event itself is
deprecated, and is replaced by `setWindowOpenHandler`.) Bare keys in window
features will now present as keys with the value `true` in the options object.
```js
// Removed in Electron 14
// Triggered by window.open('...', '', 'my-key')
webContents.on('did-create-window', (window, details) => {
if (details.additionalFeatures.includes('my-key')) {
// ...
}
})
// Replace with
webContents.on('did-create-window', (window, details) => {
if (details.options['my-key']) {
// ...
}
})
```
## Planned Breaking API Changes (13.0)
### API Changed: `session.setPermissionCheckHandler(handler)`
The `handler` methods first parameter was previously always a `webContents`, it can now sometimes be `null`. You should use the `requestingOrigin`, `embeddingOrigin` and `securityOrigin` properties to respond to the permission check correctly. As the `webContents` can be `null` it can no longer be relied on.
```js
// Old code
session.setPermissionCheckHandler((webContents, permission) => {
if (webContents.getURL().startsWith('https://google.com/') && permission === 'notification') {
return true
}
return false
})
// Replace with
session.setPermissionCheckHandler((webContents, permission, requestingOrigin) => {
if (new URL(requestingOrigin).hostname === 'google.com' && permission === 'notification') {
return true
}
return false
})
```
### Removed: `shell.moveItemToTrash()`
The deprecated synchronous `shell.moveItemToTrash()` API has been removed. Use
the asynchronous `shell.trashItem()` instead.
```js
// Removed in Electron 13
shell.moveItemToTrash(path)
// Replace with
shell.trashItem(path).then(/* ... */)
```
### Removed: `BrowserWindow` extension APIs
The deprecated extension APIs have been removed:
* `BrowserWindow.addExtension(path)`
* `BrowserWindow.addDevToolsExtension(path)`
* `BrowserWindow.removeExtension(name)`
* `BrowserWindow.removeDevToolsExtension(name)`
* `BrowserWindow.getExtensions()`
* `BrowserWindow.getDevToolsExtensions()`
Use the session APIs instead:
* `ses.loadExtension(path)`
* `ses.removeExtension(extension_id)`
* `ses.getAllExtensions()`
```js
// Removed in Electron 13
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Replace with
session.defaultSession.loadExtension(path)
```
```js
// Removed in Electron 13
BrowserWindow.removeExtension(name)
BrowserWindow.removeDevToolsExtension(name)
// Replace with
session.defaultSession.removeExtension(extension_id)
```
```js
// Removed in Electron 13
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Replace with
session.defaultSession.getAllExtensions()
```
### Removed: methods in `systemPreferences`
The following `systemPreferences` methods have been deprecated:
* `systemPreferences.isDarkMode()`
* `systemPreferences.isInvertedColorScheme()`
* `systemPreferences.isHighContrastColorScheme()`
Use the following `nativeTheme` properties instead:
* `nativeTheme.shouldUseDarkColors`
* `nativeTheme.shouldUseInvertedColorScheme`
* `nativeTheme.shouldUseHighContrastColors`
```js
// Removed in Electron 13
systemPreferences.isDarkMode()
// Replace with
nativeTheme.shouldUseDarkColors
// Removed in Electron 13
systemPreferences.isInvertedColorScheme()
// Replace with
nativeTheme.shouldUseInvertedColorScheme
// Removed in Electron 13
systemPreferences.isHighContrastColorScheme()
// Replace with
nativeTheme.shouldUseHighContrastColors
```
### Deprecated: WebContents `new-window` event
The `new-window` event of WebContents has been deprecated. It is replaced by [`webContents.setWindowOpenHandler()`](api/web-contents.md#contentssetwindowopenhandlerhandler).
```js
// Deprecated in Electron 13
webContents.on('new-window', (event) => {
event.preventDefault()
})
// Replace with
webContents.setWindowOpenHandler((details) => {
return { action: 'deny' }
})
```
## Planned Breaking API Changes (12.0)
### Removed: Pepper Flash support
Chromium has removed support for Flash, and so we must follow suit. See
Chromium's [Flash Roadmap](https://www.chromium.org/flash-roadmap) for more
details.
### Default Changed: `worldSafeExecuteJavaScript` defaults to `true`
In Electron 12, `worldSafeExecuteJavaScript` will be enabled by default. To restore
the previous behavior, `worldSafeExecuteJavaScript: false` must be specified in WebPreferences.
Please note that setting this option to `false` is **insecure**.
This option will be removed in Electron 14 so please migrate your code to support the default
value.
### Default Changed: `contextIsolation` defaults to `true`
In Electron 12, `contextIsolation` will be enabled by default. To restore
the previous behavior, `contextIsolation: false` must be specified in WebPreferences.
We [recommend having contextIsolation enabled](tutorial/security.md#3-enable-context-isolation-for-remote-content) for the security of your application.
Another implication is that `require()` cannot be used in the renderer process unless
`nodeIntegration` is `true` and `contextIsolation` is `false`.
For more details see: https://github.com/electron/electron/issues/23506
### Removed: `crashReporter.getCrashesDirectory()`
The `crashReporter.getCrashesDirectory` method has been removed. Usage
should be replaced by `app.getPath('crashDumps')`.
```js
// Removed in Electron 12
crashReporter.getCrashesDirectory()
// Replace with
app.getPath('crashDumps')
```
### Removed: `crashReporter` methods in the renderer process
The following `crashReporter` methods are no longer available in the renderer
process:
* `crashReporter.start`
* `crashReporter.getLastCrashReport`
* `crashReporter.getUploadedReports`
* `crashReporter.getUploadToServer`
* `crashReporter.setUploadToServer`
* `crashReporter.getCrashesDirectory`
They should be called only from the main process.
See [#23265](https://github.com/electron/electron/pull/23265) for more details.
### Default Changed: `crashReporter.start({ compress: true })`
The default value of the `compress` option to `crashReporter.start` has changed
from `false` to `true`. This means that crash dumps will be uploaded to the
crash ingestion server with the `Content-Encoding: gzip` header, and the body
will be compressed.
If your crash ingestion server does not support compressed payloads, you can
turn off compression by specifying `{ compress: false }` in the crash reporter
options.
### Deprecated: `remote` module
The `remote` module is deprecated in Electron 12, and will be removed in
Electron 14. It is replaced by the
[`@electron/remote`](https://github.com/electron/remote) module.
```js
// Deprecated in Electron 12:
const { BrowserWindow } = require('electron').remote
```
```js
// Replace with:
const { BrowserWindow } = require('@electron/remote')
// In the main process:
require('@electron/remote/main').initialize()
```
### Deprecated: `shell.moveItemToTrash()`
The synchronous `shell.moveItemToTrash()` has been replaced by the new,
asynchronous `shell.trashItem()`.
```js
// Deprecated in Electron 12
shell.moveItemToTrash(path)
// Replace with
shell.trashItem(path).then(/* ... */)
```
## Planned Breaking API Changes (11.0)
### Removed: `BrowserView.{destroy, fromId, fromWebContents, getAllViews}` and `id` property of `BrowserView`
The experimental APIs `BrowserView.{destroy, fromId, fromWebContents, getAllViews}`
have now been removed. Additionally, the `id` property of `BrowserView`
has also been removed.
For more detailed information, see [#23578](https://github.com/electron/electron/pull/23578).
## Planned Breaking API Changes (10.0)
### Deprecated: `companyName` argument to `crashReporter.start()`
The `companyName` argument to `crashReporter.start()`, which was previously
required, is now optional, and further, is deprecated. To get the same
behavior in a non-deprecated way, you can pass a `companyName` value in
`globalExtra`.
```js
// Deprecated in Electron 10
crashReporter.start({ companyName: 'Umbrella Corporation' })
// Replace with
crashReporter.start({ globalExtra: { _companyName: 'Umbrella Corporation' } })
```
### Deprecated: `crashReporter.getCrashesDirectory()`
The `crashReporter.getCrashesDirectory` method has been deprecated. Usage
should be replaced by `app.getPath('crashDumps')`.
```js
// Deprecated in Electron 10
crashReporter.getCrashesDirectory()
// Replace with
app.getPath('crashDumps')
```
### Deprecated: `crashReporter` methods in the renderer process
Calling the following `crashReporter` methods from the renderer process is
deprecated:
* `crashReporter.start`
* `crashReporter.getLastCrashReport`
* `crashReporter.getUploadedReports`
* `crashReporter.getUploadToServer`
* `crashReporter.setUploadToServer`
* `crashReporter.getCrashesDirectory`
The only non-deprecated methods remaining in the `crashReporter` module in the
renderer are `addExtraParameter`, `removeExtraParameter` and `getParameters`.
All above methods remain non-deprecated when called from the main process.
See [#23265](https://github.com/electron/electron/pull/23265) for more details.
### Deprecated: `crashReporter.start({ compress: false })`
Setting `{ compress: false }` in `crashReporter.start` is deprecated. Nearly
all crash ingestion servers support gzip compression. This option will be
removed in a future version of Electron.
### Default Changed: `enableRemoteModule` defaults to `false`
In Electron 9, using the remote module without explicitly enabling it via the
`enableRemoteModule` WebPreferences option began emitting a warning. In
Electron 10, the remote module is now disabled by default. To use the remote
module, `enableRemoteModule: true` must be specified in WebPreferences:
```js
const w = new BrowserWindow({
webPreferences: {
enableRemoteModule: true
}
})
```
We [recommend moving away from the remote
module](https://medium.com/@nornagon/electrons-remote-module-considered-harmful-70d69500f31).
### `protocol.unregisterProtocol`
### `protocol.uninterceptProtocol`
The APIs are now synchronous and the optional callback is no longer needed.
```javascript
// Deprecated
protocol.unregisterProtocol(scheme, () => { /* ... */ })
// Replace with
protocol.unregisterProtocol(scheme)
```
### `protocol.registerFileProtocol`
### `protocol.registerBufferProtocol`
### `protocol.registerStringProtocol`
### `protocol.registerHttpProtocol`
### `protocol.registerStreamProtocol`
### `protocol.interceptFileProtocol`
### `protocol.interceptStringProtocol`
### `protocol.interceptBufferProtocol`
### `protocol.interceptHttpProtocol`
### `protocol.interceptStreamProtocol`
The APIs are now synchronous and the optional callback is no longer needed.
```javascript
// Deprecated
protocol.registerFileProtocol(scheme, handler, () => { /* ... */ })
// Replace with
protocol.registerFileProtocol(scheme, handler)
```
The registered or intercepted protocol does not have effect on current page
until navigation happens.
### `protocol.isProtocolHandled`
This API is deprecated and users should use `protocol.isProtocolRegistered`
and `protocol.isProtocolIntercepted` instead.
```javascript
// Deprecated
protocol.isProtocolHandled(scheme).then(() => { /* ... */ })
// Replace with
const isRegistered = protocol.isProtocolRegistered(scheme)
const isIntercepted = protocol.isProtocolIntercepted(scheme)
```
## Planned Breaking API Changes (9.0)
### Default Changed: Loading non-context-aware native modules in the renderer process is disabled by default
As of Electron 9 we do not allow loading of non-context-aware native modules in
the renderer process. This is to improve security, performance and maintainability
of Electron as a project.
If this impacts you, you can temporarily set `app.allowRendererProcessReuse` to `false`
to revert to the old behavior. This flag will only be an option until Electron 11 so
you should plan to update your native modules to be context aware.
For more detailed information see [#18397](https://github.com/electron/electron/issues/18397).
### Deprecated: `BrowserWindow` extension APIs
The following extension APIs have been deprecated:
* `BrowserWindow.addExtension(path)`
* `BrowserWindow.addDevToolsExtension(path)`
* `BrowserWindow.removeExtension(name)`
* `BrowserWindow.removeDevToolsExtension(name)`
* `BrowserWindow.getExtensions()`
* `BrowserWindow.getDevToolsExtensions()`
Use the session APIs instead:
* `ses.loadExtension(path)`
* `ses.removeExtension(extension_id)`
* `ses.getAllExtensions()`
```js
// Deprecated in Electron 9
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Replace with
session.defaultSession.loadExtension(path)
```
```js
// Deprecated in Electron 9
BrowserWindow.removeExtension(name)
BrowserWindow.removeDevToolsExtension(name)
// Replace with
session.defaultSession.removeExtension(extension_id)
```
```js
// Deprecated in Electron 9
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Replace with
session.defaultSession.getAllExtensions()
```
### Removed: `<webview>.getWebContents()`
This API, which was deprecated in Electron 8.0, is now removed.
```js
// Removed in Electron 9.0
webview.getWebContents()
// Replace with
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())
```
### Removed: `webFrame.setLayoutZoomLevelLimits()`
Chromium has removed support for changing the layout zoom level limits, and it
is beyond Electron's capacity to maintain it. The function was deprecated in
Electron 8.x, and has been removed in Electron 9.x. The layout zoom level limits
are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
### Behavior Changed: Sending non-JS objects over IPC now throws an exception
In Electron 8.0, IPC was changed to use the Structured Clone Algorithm,
bringing significant performance improvements. To help ease the transition, the
old IPC serialization algorithm was kept and used for some objects that aren't
serializable with Structured Clone. In particular, DOM objects (e.g. `Element`,
`Location` and `DOMMatrix`), Node.js objects backed by C++ classes (e.g.
`process.env`, some members of `Stream`), and Electron objects backed by C++
classes (e.g. `WebContents`, `BrowserWindow` and `WebFrame`) are not
serializable with Structured Clone. Whenever the old algorithm was invoked, a
deprecation warning was printed.
In Electron 9.0, the old serialization algorithm has been removed, and sending
such non-serializable objects will now throw an "object could not be cloned"
error.
### API Changed: `shell.openItem` is now `shell.openPath`
The `shell.openItem` API has been replaced with an asynchronous `shell.openPath` API.
You can see the original API proposal and reasoning [here](https://github.com/electron/governance/blob/main/wg-api/spec-documents/shell-openitem.md).
## Planned Breaking API Changes (8.0)
### Behavior Changed: Values sent over IPC are now serialized with Structured Clone Algorithm
The algorithm used to serialize objects sent over IPC (through
`ipcRenderer.send`, `ipcRenderer.sendSync`, `WebContents.send` and related
methods) has been switched from a custom algorithm to V8's built-in [Structured
Clone Algorithm][SCA], the same algorithm used to serialize messages for
`postMessage`. This brings about a 2x performance improvement for large
messages, but also brings some breaking changes in behavior.
* Sending Functions, Promises, WeakMaps, WeakSets, or objects containing any
such values, over IPC will now throw an exception, instead of silently
converting the functions to `undefined`.
```js
// Previously:
ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
// => results in { value: 3 } arriving in the main process
// From Electron 8:
ipcRenderer.send('channel', { value: 3, someFunction: () => {} })
// => throws Error("() => {} could not be cloned.")
```
* `NaN`, `Infinity` and `-Infinity` will now be correctly serialized, instead
of being converted to `null`.
* Objects containing cyclic references will now be correctly serialized,
instead of being converted to `null`.
* `Set`, `Map`, `Error` and `RegExp` values will be correctly serialized,
instead of being converted to `{}`.
* `BigInt` values will be correctly serialized, instead of being converted to
`null`.
* Sparse arrays will be serialized as such, instead of being converted to dense
arrays with `null`s.
* `Date` objects will be transferred as `Date` objects, instead of being
converted to their ISO string representation.
* Typed Arrays (such as `Uint8Array`, `Uint16Array`, `Uint32Array` and so on)
will be transferred as such, instead of being converted to Node.js `Buffer`.
* Node.js `Buffer` objects will be transferred as `Uint8Array`s. You can
convert a `Uint8Array` back to a Node.js `Buffer` by wrapping the underlying
`ArrayBuffer`:
```js
Buffer.from(value.buffer, value.byteOffset, value.byteLength)
```
Sending any objects that aren't native JS types, such as DOM objects (e.g.
`Element`, `Location`, `DOMMatrix`), Node.js objects (e.g. `process.env`,
`Stream`), or Electron objects (e.g. `WebContents`, `BrowserWindow`,
`WebFrame`) is deprecated. In Electron 8, these objects will be serialized as
before with a DeprecationWarning message, but starting in Electron 9, sending
these kinds of objects will throw a 'could not be cloned' error.
[SCA]: https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Structured_clone_algorithm
### Deprecated: `<webview>.getWebContents()`
This API is implemented using the `remote` module, which has both performance
and security implications. Therefore its usage should be explicit.
```js
// Deprecated
webview.getWebContents()
// Replace with
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())
```
However, it is recommended to avoid using the `remote` module altogether.
```js
// main
const { ipcMain, webContents } = require('electron')
const getGuestForWebContents = (webContentsId, contents) => {
const guest = webContents.fromId(webContentsId)
if (!guest) {
throw new Error(`Invalid webContentsId: ${webContentsId}`)
}
if (guest.hostWebContents !== contents) {
throw new Error('Access denied to webContents')
}
return guest
}
ipcMain.handle('openDevTools', (event, webContentsId) => {
const guest = getGuestForWebContents(webContentsId, event.sender)
guest.openDevTools()
})
// renderer
const { ipcRenderer } = require('electron')
ipcRenderer.invoke('openDevTools', webview.getWebContentsId())
```
### Deprecated: `webFrame.setLayoutZoomLevelLimits()`
Chromium has removed support for changing the layout zoom level limits, and it
is beyond Electron's capacity to maintain it. The function will emit a warning
in Electron 8.x, and cease to exist in Electron 9.x. The layout zoom level
limits are now fixed at a minimum of 0.25 and a maximum of 5.0, as defined
[here](https://chromium.googlesource.com/chromium/src/+/938b37a6d2886bf8335fc7db792f1eb46c65b2ae/third_party/blink/common/page/page_zoom.cc#11).
### Deprecated events in `systemPreferences`
The following `systemPreferences` events have been deprecated:
* `inverted-color-scheme-changed`
* `high-contrast-color-scheme-changed`
Use the new `updated` event on the `nativeTheme` module instead.
```js
// Deprecated
systemPreferences.on('inverted-color-scheme-changed', () => { /* ... */ })
systemPreferences.on('high-contrast-color-scheme-changed', () => { /* ... */ })
// Replace with
nativeTheme.on('updated', () => { /* ... */ })
```
### Deprecated: methods in `systemPreferences`
The following `systemPreferences` methods have been deprecated:
* `systemPreferences.isDarkMode()`
* `systemPreferences.isInvertedColorScheme()`
* `systemPreferences.isHighContrastColorScheme()`
Use the following `nativeTheme` properties instead:
* `nativeTheme.shouldUseDarkColors`
* `nativeTheme.shouldUseInvertedColorScheme`
* `nativeTheme.shouldUseHighContrastColors`
```js
// Deprecated
systemPreferences.isDarkMode()
// Replace with
nativeTheme.shouldUseDarkColors
// Deprecated
systemPreferences.isInvertedColorScheme()
// Replace with
nativeTheme.shouldUseInvertedColorScheme
// Deprecated
systemPreferences.isHighContrastColorScheme()
// Replace with
nativeTheme.shouldUseHighContrastColors
```
## Planned Breaking API Changes (7.0)
### Deprecated: Atom.io Node Headers URL
This is the URL specified as `disturl` in a `.npmrc` file or as the `--dist-url`
command line flag when building native Node modules. Both will be supported for
the foreseeable future but it is recommended that you switch.
Deprecated: https://atom.io/download/electron
Replace with: https://electronjs.org/headers
### API Changed: `session.clearAuthCache()` no longer accepts options
The `session.clearAuthCache` API no longer accepts options for what to clear, and instead unconditionally clears the whole cache.
```js
// Deprecated
session.clearAuthCache({ type: 'password' })
// Replace with
session.clearAuthCache()
```
### API Changed: `powerMonitor.querySystemIdleState` is now `powerMonitor.getSystemIdleState`
```js
// Removed in Electron 7.0
powerMonitor.querySystemIdleState(threshold, callback)
// Replace with synchronous API
const idleState = powerMonitor.getSystemIdleState(threshold)
```
### API Changed: `powerMonitor.querySystemIdleTime` is now `powerMonitor.getSystemIdleTime`
```js
// Removed in Electron 7.0
powerMonitor.querySystemIdleTime(callback)
// Replace with synchronous API
const idleTime = powerMonitor.getSystemIdleTime()
```
### API Changed: `webFrame.setIsolatedWorldInfo` replaces separate methods
```js
// Removed in Electron 7.0
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)
webFrame.setIsolatedWorldHumanReadableName(worldId, name)
webFrame.setIsolatedWorldSecurityOrigin(worldId, securityOrigin)
// Replace with
webFrame.setIsolatedWorldInfo(
worldId,
{
securityOrigin: 'some_origin',
name: 'human_readable_name',
csp: 'content_security_policy'
})
```
### Removed: `marked` property on `getBlinkMemoryInfo`
This property was removed in Chromium 77, and as such is no longer available.
### Behavior Changed: `webkitdirectory` attribute for `<input type="file"/>` now lists directory contents
The `webkitdirectory` property on HTML file inputs allows them to select folders.
Previous versions of Electron had an incorrect implementation where the `event.target.files`
of the input returned a `FileList` that returned one `File` corresponding to the selected folder.
As of Electron 7, that `FileList` is now list of all files contained within
the folder, similarly to Chrome, Firefox, and Edge
([link to MDN docs](https://developer.mozilla.org/en-US/docs/Web/API/HTMLInputElement/webkitdirectory)).
As an illustration, take a folder with this structure:
```console
folder
├── file1
├── file2
└── file3
```
In Electron <=6, this would return a `FileList` with a `File` object for:
```console
path/to/folder
```
In Electron 7, this now returns a `FileList` with a `File` object for:
```console
/path/to/folder/file3
/path/to/folder/file2
/path/to/folder/file1
```
Note that `webkitdirectory` no longer exposes the path to the selected folder.
If you require the path to the selected folder rather than the folder contents,
see the `dialog.showOpenDialog` API ([link](api/dialog.md#dialogshowopendialogbrowserwindow-options)).
### API Changed: Callback-based versions of promisified APIs
Electron 5 and Electron 6 introduced Promise-based versions of existing
asynchronous APIs and deprecated their older, callback-based counterparts.
In Electron 7, all deprecated callback-based APIs are now removed.
These functions now only return Promises:
* `app.getFileIcon()` [#15742](https://github.com/electron/electron/pull/15742)
* `app.dock.show()` [#16904](https://github.com/electron/electron/pull/16904)

* `shell.openExternal()` [#16176](https://github.com/electron/electron/pull/16176)
* `webContents.loadFile()` [#15855](https://github.com/electron/electron/pull/15855)
* `webContents.loadURL()` [#15855](https://github.com/electron/electron/pull/15855)
* `webContents.hasServiceWorker()` [#16535](https://github.com/electron/electron/pull/16535)

* `win.capturePage()` [#15743](https://github.com/electron/electron/pull/15743)
These functions now have two forms, synchronous and Promise-based asynchronous:
* `dialog.showMessageBox()`/`dialog.showMessageBoxSync()` [#17298](https://github.com/electron/electron/pull/17298)
* `dialog.showOpenDialog()`/`dialog.showOpenDialogSync()` [#16973](https://github.com/electron/electron/pull/16973)
* `dialog.showSaveDialog()`/`dialog.showSaveDialogSync()` [#17054](https://github.com/electron/electron/pull/17054)

// Replace with
win.removeMenu()
```
### API Changed: `electron.screen` in the renderer process should be accessed via `remote`
```js
// Deprecated
require('electron').screen
// Replace with
require('electron').remote.screen
```

```js
// Deprecated
require('child_process')
// Replace with
require('electron').remote.require('child_process')
// Deprecated
require('fs')
// Replace with
require('electron').remote.require('fs')
// Deprecated

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

// Replace with
app.releaseSingleInstanceLock()
```
### `app.getGPUInfo`
```js
app.getGPUInfo('complete')
// Now behaves the same with `basic` on macOS
app.getGPUInfo('basic')
```
### `win_delay_load_hook`
When building native modules for windows, the `win_delay_load_hook` variable in
the module's `binding.gyp` must be true (which is the default). If this hook is
not present, then the native module will fail to load on Windows, with an error
message like `Cannot find module`. See the [native module
guide](/docs/tutorial/using-native-node-modules.md) for more.
## Breaking API Changes (3.0)
The following list includes the breaking API changes in Electron 3.0.

```js
// Deprecated
webFrame.registerURLSchemeAsSecure('app')
// Replace with
protocol.registerStandardSchemes(['app'], { secure: true })
// Deprecated
webFrame.registerURLSchemeAsPrivileged('app', { secure: true })

command line flag when building native Node modules.
Deprecated: https://atom.io/download/atom-shell
Replace with: https://atom.io/download/electron
## Breaking API Changes (2.0)
The following list includes the breaking API changes made in Electron 2.0.
### `BrowserWindow`
```js
// Deprecated
const optionsA = { titleBarStyle: 'hidden-inset' }
const windowA = new BrowserWindow(optionsA)
// Replace with
const optionsB = { titleBarStyle: 'hiddenInset' }
const windowB = new BrowserWindow(optionsB)
```
### `menu`
```js
// Removed
menu.popup(browserWindow, 100, 200, 2)
// Replaced with
menu.popup(browserWindow, { x: 100, y: 200, positioningItem: 2 })
```
### `nativeImage`
```js
// Removed

// Replaced with
nativeImage.toPNG()
// Removed
nativeImage.toJpeg()
// Replaced with

### `process`
* `process.versions.electron` and `process.version.chrome` will be made
read-only properties for consistency with the other `process.versions`
properties set by Node.
### `webContents`
```js
// Removed
webContents.setZoomLevelLimits(1, 2)
// Replaced with
webContents.setVisualZoomLevelLimits(1, 2)

// Replaced with
webview.setVisualZoomLevelLimits(1, 2)
```
### Duplicate ARM Assets
Each Electron release includes two identical ARM builds with slightly different
filenames, like `electron-v1.7.3-linux-arm.zip` and
`electron-v1.7.3-linux-armv7l.zip`. The asset with the `v7l` prefix was added
to clarify to users which ARM version it supports, and to disambiguate it from
future armv6l and arm64 assets that may be produced.
The file _without the prefix_ is still being published to avoid breaking any
setups that may be consuming it. Starting at 2.0, the unprefixed file will
no longer be published.
For details, see
[6986](https://github.com/electron/electron/pull/6986)
and
[7189](https://github.com/electron/electron/pull/7189).

### 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.
### Problem Description
The Security [doc](https://www.electronjs.org/docs/latest/tutorial/security#3-enable-context-isolation-for-remote-content) states:
>Enable Context Isolation for remote content
Based on some of the discussion in [this issue](https://github.com/electron/electron/issues/23506) (specifically [here](https://github.com/electron/electron/issues/23506#issuecomment-922092517)), it sounds like Electron is recommending that we enable `contextIsolation` for *all* content, remote or local.
Should the Sec doc be updated in that case?
### Proposed Solution
Remove the bit about "remote content" from that section
### Alternatives Considered
n/a

## Preface
As web developers, we usually enjoy the strong security net of the browser —
the risks associated with the code we write are relatively small. Our websites
are granted limited powers in a sandbox, and we trust that our users enjoy a
browser built by a large team of engineers that is able to quickly respond to
newly discovered security threats.
When working with Electron, it is important to understand that Electron is not
a web browser. It allows you to build feature-rich desktop applications with
familiar web technologies, but your code wields much greater power. JavaScript
can access the filesystem, user shell, and more. This allows you to build
high quality native applications, but the inherent security risks scale with
the additional powers granted to your code.
With that in mind, be aware that displaying arbitrary content from untrusted
sources poses a severe security risk that Electron is not intended to handle.
In fact, the most popular Electron apps (Atom, Slack, Visual Studio Code, etc)
display primarily local content (or trusted, secure remote content without Node
integration) — if your application executes code from an online source, it is
your responsibility to ensure that the code is not malicious.
## General guidelines
### Security is everyone's responsibility
It is important to remember that the security of your Electron application is
the result of the overall security of the framework foundation
(*Chromium*, *Node.js*), Electron itself, all NPM dependencies and
your code. As such, it is your responsibility to follow a few important best
practices:
* **Keep your application up-to-date with the latest Electron framework release.**
When releasing your product, you’re also shipping a bundle composed of Electron,
Chromium shared library and Node.js. Vulnerabilities affecting these components
may impact the security of your application. By updating Electron to the latest
version, you ensure that critical vulnerabilities (such as *nodeIntegration bypasses*)
are already patched and cannot be exploited in your application. For more information,
see "[Use a current version of Electron](#16-use-a-current-version-of-electron)".
* **Evaluate your dependencies.** While NPM provides half a million reusable packages,
it is your responsibility to choose trusted 3rd-party libraries. If you use outdated
libraries affected by known vulnerabilities or rely on poorly maintained code,
your application security could be in jeopardy.
* **Adopt secure coding practices.** The first line of defense for your application
is your own code. Common web vulnerabilities, such as Cross-Site Scripting (XSS),
have a higher security impact on Electron applications hence it is highly recommended
to adopt secure software development best practices and perform security testing.
### Isolation for untrusted content
A security issue exists whenever you receive code from an untrusted source (e.g.
a remote server) and execute it locally. As an example, consider a remote
website being displayed inside a default [`BrowserWindow`][browser-window]. If
an attacker somehow manages to change said content (either by attacking the
source directly, or by sitting between your app and the actual destination), they
will be able to execute native code on the user's machine.
:::warning
Under no circumstances should you load and execute remote code with
Node.js integration enabled. Instead, use only local files (packaged together
with your application) to execute Node.js code. To display remote content, use
the [`<webview>`][webview-tag] tag or [`BrowserView`][browser-view], make sure
to disable the `nodeIntegration` and enable `contextIsolation`.
:::
:::info Electron security warnings
Security warnings and recommendations are printed to the developer console.
They only show up when the binary's name is Electron, indicating that a developer
is currently looking at the console.
You can force-enable or force-disable these warnings by setting
`ELECTRON_ENABLE_SECURITY_WARNINGS` or `ELECTRON_DISABLE_SECURITY_WARNINGS` on
either `process.env` or the `window` object.

To automate the detection of misconfigurations and insecure patterns, it is
possible to use
[Electronegativity](https://github.com/doyensec/electronegativity). For
additional details on potential weaknesses and implementation bugs when
developing applications using Electron, please refer to this [guide for
developers and auditors](https://doyensec.com/resources/us-17-Carettoni-Electronegativity-A-Study-Of-Electron-Security-wp.pdf).
### 1. Only load secure content
Any resources not included with your application should be loaded using a
secure protocol like `HTTPS`. In other words, do not use insecure protocols
like `HTTP`. Similarly, we recommend the use of `WSS` over `WS`, `FTPS` over
`FTP`, and so on.
#### Why?
`HTTPS` has three main benefits:
1. It authenticates the remote server, ensuring your app connects to the correct
host instead of an impersonator.
1. It ensures data integrity, asserting that the data was not modified while in
transit between your application and the host.
1. It encrypts the traffic between your user and the destination host, making it
more difficult to eavesdrop on the information sent between your app and
the host.
#### How?
```js title='main.js (Main Process)'
// Bad
browserWindow.loadURL('http://example.com')
// Good
browserWindow.loadURL('https://example.com')
```
```html title='index.html (Renderer Process)'
<!-- Bad -->
<script crossorigin src="http://example.com/react.js"></script>
<link rel="stylesheet" href="http://example.com/style.css">
<!-- Good -->
<script crossorigin src="https://example.com/react.js"></script>
<link rel="stylesheet" href="https://example.com/style.css">
```
### 2. Do not enable Node.js integration for remote content
:::info
This recommendation is the default behavior in Electron since 5.0.0.
:::
It is paramount that you do not enable Node.js integration in any renderer
([`BrowserWindow`][browser-window], [`BrowserView`][browser-view], or
[`<webview>`][webview-tag]) that loads remote content. The goal is to limit the
powers you grant to remote content, thus making it dramatically more difficult
for an attacker to harm your users should they gain the ability to execute
JavaScript on your website.
After this, you can grant additional permissions for specific hosts. For example,
if you are opening a BrowserWindow pointed at `https://example.com/`, you can
give that website exactly the abilities it needs, but no more.
#### Why?
A cross-site-scripting (XSS) attack is more dangerous if an attacker can jump
out of the renderer process and execute code on the user's computer.
Cross-site-scripting attacks are fairly common - and while an issue, their
power is usually limited to messing with the website that they are executed on.
Disabling Node.js integration helps prevent an XSS from being escalated into a
so-called "Remote Code Execution" (RCE) attack.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
contextIsolation: false,
nodeIntegration: true,
nodeIntegrationInWorker: true
}
})
mainWindow.loadURL('https://example.com')
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(app.getAppPath(), 'preload.js')
}
})
mainWindow.loadURL('https://example.com')
```
```html title='index.html (Renderer Process)'
<!-- Bad -->
<webview nodeIntegration src="page.html"></webview>
<!-- Good -->
<webview src="page.html"></webview>
```
When disabling Node.js integration, you can still expose APIs to your website that
do consume Node.js modules or features. Preload scripts continue to have access
to `require` and other Node.js features, allowing developers to expose a custom
API to remotely loaded content via the [contextBridge API](../api/context-bridge.md).
### 3. Enable Context Isolation for remote content
:::info
This recommendation is the default behavior in Electron since 12.0.0.
:::
Context isolation is an Electron feature that allows developers to run code
in preload scripts and in Electron APIs in a dedicated JavaScript context. In
practice, that means that global objects like `Array.prototype.push` or
`JSON.parse` cannot be modified by scripts running in the renderer process.
Electron uses the same technology as Chromium's [Content Scripts](https://developer.chrome.com/extensions/content_scripts#execution-environment)
to enable this behavior.
Even when `nodeIntegration: false` is used, to truly enforce strong isolation
and prevent the use of Node primitives `contextIsolation` **must** also be used.
:::info
For more information on what `contextIsolation` is and how to enable it please
see our dedicated [Context Isolation](context-isolation.md) document.
:::info
### 4. Enable process sandboxing
[Sandboxing](https://chromium.googlesource.com/chromium/src/+/HEAD/docs/design/sandbox.md)
is a Chromium feature that uses the operating system to
significantly limit what renderer processes have access to. You should enable
the sandbox in all renderers. Loading, reading or processing any untrusted
content in an unsandboxed process, including the main process, is not advised.
:::info
For more information on what `contextIsolation` is and how to enable it please
see our dedicated [Process Sandboxing](sandbox.md) document.
:::info
### 5. Handle session permission requests from remote content
You may have seen permission requests while using Chrome: they pop up whenever
the website attempts to use a feature that the user has to manually approve (
like notifications).
The API is based on the [Chromium permissions API](https://developer.chrome.com/extensions/permissions)
and implements the same types of permissions.
#### Why?
By default, Electron will automatically approve all permission requests unless
the developer has manually configured a custom handler. While a solid default,
security-conscious developers might want to assume the very opposite.
#### How?
```js title='main.js (Main Process)'
const { session } = require('electron')
const URL = require('url').URL
session
.fromPartition('some-partition')
.setPermissionRequestHandler((webContents, permission, callback) => {
const parsedUrl = new URL(webContents.getURL())
if (permission === 'notifications') {
// Approves the permissions request
callback(true)
}
// Verify URL
if (parsedUrl.protocol !== 'https:' || parsedUrl.host !== 'example.com') {
// Denies the permissions request
return callback(false)
}
})
```
### 6. Do not disable `webSecurity`
:::info
This recommendation is Electron's default.
:::
You may have already guessed that disabling the `webSecurity` property on a
renderer process ([`BrowserWindow`][browser-window],
[`BrowserView`][browser-view], or [`<webview>`][webview-tag]) disables crucial
security features.
Do not disable `webSecurity` in production applications.
#### Why?
Disabling `webSecurity` will disable the same-origin policy and set
`allowRunningInsecureContent` property to `true`. In other words, it allows
the execution of insecure code from different domains.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
webSecurity: false
}
})
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow()
```
```html title='index.html (Renderer Process)'
<!-- Bad -->
<webview disablewebsecurity src="page.html"></webview>
<!-- Good -->
<webview src="page.html"></webview>
```
### 7. Define a Content Security Policy
A Content Security Policy (CSP) is an additional layer of protection against
cross-site-scripting attacks and data injection attacks. We recommend that they
be enabled by any website you load inside Electron.
#### Why?
CSP allows the server serving content to restrict and control the resources
Electron can load for that given web page. `https://example.com` should
be allowed to load scripts from the origins you defined while scripts from
`https://evil.attacker.com` should not be allowed to run. Defining a CSP is an
easy way to improve your application's security.
#### How?
The following CSP will allow Electron to execute scripts from the current
website and from `apis.example.com`.
```plaintext
// Bad
Content-Security-Policy: '*'
// Good
Content-Security-Policy: script-src 'self' https://apis.example.com
```
#### CSP HTTP headers
Electron respects the [`Content-Security-Policy` HTTP header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy)
which can be set using Electron's
[`webRequest.onHeadersReceived`](../api/web-request.md#webrequestonheadersreceivedfilter-listener)
handler:
```javascript title='main.js (Main Process)'
const { session } = require('electron')
session.defaultSession.webRequest.onHeadersReceived((details, callback) => {
callback({
responseHeaders: {
...details.responseHeaders,
'Content-Security-Policy': ['default-src \'none\'']
}
})
})
```
#### CSP meta tag
CSP's preferred delivery mechanism is an HTTP header. However, it is not possible
to use this method when loading a resource using the `file://` protocol. It can
be useful in some cases to set a policy on a page directly in the markup using a
`<meta>` tag:
```html title='index.html (Renderer Process)'
<meta http-equiv="Content-Security-Policy" content="default-src 'none'">
```
### 8. Do not enable `allowRunningInsecureContent`
:::info
This recommendation is Electron's default.
:::
By default, Electron will not allow websites loaded over `HTTPS` to load and
execute scripts, CSS, or plugins from insecure sources (`HTTP`). Setting the
property `allowRunningInsecureContent` to `true` disables that protection.
Loading the initial HTML of a website over `HTTPS` and attempting to load
subsequent resources via `HTTP` is also known as "mixed content".
#### Why?
Loading content over `HTTPS` assures the authenticity and integrity
of the loaded resources while encrypting the traffic itself. See the section on
[only displaying secure content](#1-only-load-secure-content) for more details.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
allowRunningInsecureContent: true
}
})
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow({})
```
### 9. Do not enable experimental features
:::info
This recommendation is Electron's default.
:::
Advanced users of Electron can enable experimental Chromium features using the
`experimentalFeatures` property.
#### Why?
Experimental features are, as the name suggests, experimental and have not been
enabled for all Chromium users. Furthermore, their impact on Electron as a whole
has likely not been tested.
Legitimate use cases exist, but unless you know what you are doing, you should
not enable this property.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
experimentalFeatures: true
}
})
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow({})
```
### 10. Do not use `enableBlinkFeatures`
:::info
This recommendation is Electron's default.
:::
Blink is the name of the rendering engine behind Chromium. As with
`experimentalFeatures`, the `enableBlinkFeatures` property allows developers to
enable features that have been disabled by default.
#### Why?
Generally speaking, there are likely good reasons if a feature was not enabled
by default. Legitimate use cases for enabling specific features exist. As a
developer, you should know exactly why you need to enable a feature, what the
ramifications are, and how it impacts the security of your application. Under
no circumstances should you enable features speculatively.
#### How?
```js title='main.js (Main Process)'
// Bad
const mainWindow = new BrowserWindow({
webPreferences: {
enableBlinkFeatures: 'ExecCommandInJavaScript'
}
})
```
```js title='main.js (Main Process)'
// Good
const mainWindow = new BrowserWindow()
```
### 11. Do not use `allowpopups` for WebViews
:::info
This recommendation is Electron's default.
:::
If you are using [`<webview>`][webview-tag], you might need the pages and scripts
loaded in your `<webview>` tag to open new windows. The `allowpopups` attribute
enables them to create new [`BrowserWindows`][browser-window] using the
`window.open()` method. `<webview>` tags are otherwise not allowed to create new
windows.
#### Why?
If you do not need popups, you are better off not allowing the creation of
new [`BrowserWindows`][browser-window] by default. This follows the principle
of minimally required access: Don't let a website create new popups unless
you know it needs that feature.
#### How?
```html title='index.html (Renderer Process)'
<!-- Bad -->
<webview allowpopups src="page.html"></webview>
<!-- Good -->
<webview src="page.html"></webview>
```
### 12. Verify WebView options before creation
A WebView created in a renderer process that does not have Node.js integration
enabled will not be able to enable integration itself. However, a WebView will
always create an independent renderer process with its own `webPreferences`.
It is a good idea to control the creation of new [`<webview>`][webview-tag] tags
from the main process and to verify that their webPreferences do not disable
security features.
#### Why?
Since `<webview>` live in the DOM, they can be created by a script running on your
website even if Node.js integration is otherwise disabled.
Electron enables developers to disable various security features that control
a renderer process. In most cases, developers do not need to disable any of
those features - and you should therefore not allow different configurations
for newly created [`<webview>`][webview-tag] tags.
#### How?
Before a [`<webview>`][webview-tag] tag is attached, Electron will fire the
`will-attach-webview` event on the hosting `webContents`. Use the event to
prevent the creation of `webViews` with possibly insecure options.
```js title='main.js (Main Process)'
app.on('web-contents-created', (event, contents) => {
contents.on('will-attach-webview', (event, webPreferences, params) => {
// Strip away preload scripts if unused or verify their location is legitimate
delete webPreferences.preload
// Disable Node.js integration
webPreferences.nodeIntegration = false
// Verify URL being loaded
if (!params.src.startsWith('https://example.com/')) {
event.preventDefault()
}
})
})
```
Again, this list merely minimizes the risk, but does not remove it. If your goal
is to display a website, a browser will be a more secure option.
### 13. Disable or limit navigation
If your app has no need to navigate or only needs to navigate to known pages,
it is a good idea to limit navigation outright to that known scope, disallowing
any other kinds of navigation.
#### Why?
Navigation is a common attack vector. If an attacker can convince your app to
navigate away from its current page, they can possibly force your app to open
web sites on the Internet. Even if your `webContents` are configured to be more
secure (like having `nodeIntegration` disabled or `contextIsolation` enabled),
getting your app to open a random web site will make the work of exploiting your
app a lot easier.
A common attack pattern is that the attacker convinces your app's users to
interact with the app in such a way that it navigates to one of the attacker's
pages. This is usually done via links, plugins, or other user-generated content.
#### How?
If your app has no need for navigation, you can call `event.preventDefault()`
in a [`will-navigate`][will-navigate] handler. If you know which pages your app
might navigate to, check the URL in the event handler and only let navigation
occur if it matches the URLs you're expecting.
We recommend that you use Node's parser for URLs. Simple string comparisons can
sometimes be fooled - a `startsWith('https://example.com')` test would let
`https://example.com.attacker.com` through.
```js title='main.js (Main Process)'
const URL = require('url').URL
app.on('web-contents-created', (event, contents) => {
contents.on('will-navigate', (event, navigationUrl) => {
const parsedUrl = new URL(navigationUrl)
if (parsedUrl.origin !== 'https://example.com') {
event.preventDefault()
}
})
})
```
### 14. Disable or limit creation of new windows
If you have a known set of windows, it's a good idea to limit the creation of
additional windows in your app.
#### Why?
Much like navigation, the creation of new `webContents` is a common attack
vector. Attackers attempt to convince your app to create new windows, frames,
or other renderer processes with more privileges than they had before; or
with pages opened that they couldn't open before.
If you have no need to create windows in addition to the ones you know you'll
need to create, disabling the creation buys you a little bit of extra
security at no cost. This is commonly the case for apps that open one
`BrowserWindow` and do not need to open an arbitrary number of additional
windows at runtime.
#### How?
[`webContents`][web-contents] will delegate to its [window open
handler][window-open-handler] before creating new windows. The handler will
receive, amongst other parameters, the `url` the window was requested to open
and the options used to create it. We recommend that you register a handler to
monitor the creation of windows, and deny any unexpected window creation.
```js title='main.js (Main Process)'
const { shell } = require('electron')
app.on('web-contents-created', (event, contents) => {
contents.setWindowOpenHandler(({ url }) => {
// In this example, we'll ask the operating system
// to open this event's url in the default browser.
//
// See the following item for considerations regarding what
// URLs should be allowed through to shell.openExternal.
if (isSafeForExternalOpen(url)) {
setImmediate(() => {
shell.openExternal(url)
})
}
return { action: 'deny' }
})
})
```
### 15. Do not use `shell.openExternal` with untrusted content
The shell module's [`openExternal`][open-external] API allows opening a given
protocol URI with the desktop's native utilities. On macOS, for instance, this
function is similar to the `open` terminal command utility and will open the
specific application based on the URI and filetype association.
#### Why?
Improper use of [`openExternal`][open-external] can be leveraged to compromise
the user's host. When openExternal is used with untrusted content, it can be
leveraged to execute arbitrary commands.
#### How?
```js title='main.js (Main Process)'
// Bad
const { shell } = require('electron')
shell.openExternal(USER_CONTROLLED_DATA_HERE)
```
```js title='main.js (Main Process)'
// Good
const { shell } = require('electron')
shell.openExternal('https://example.com/index.html')
```
### 16. Use a current version of Electron
You should strive for always using the latest available version of Electron.
Whenever a new major version is released, you should attempt to update your
app as quickly as possible.
#### Why?
An application built with an older version of Electron, Chromium, and Node.js
is an easier target than an application that is using more recent versions of
those components. Generally speaking, security issues and exploits for older
versions of Chromium and Node.js are more widely available.
Both Chromium and Node.js are impressive feats of engineering built by
thousands of talented developers. Given their popularity, their security is
carefully tested and analyzed by equally skilled security researchers. Many of
those researchers [disclose vulnerabilities responsibly][responsible-disclosure],
which generally means that researchers will give Chromium and Node.js some time
to fix issues before publishing them. Your application will be more secure if
it is running a recent version of Electron (and thus, Chromium and Node.js) for
which potential security issues are not as widely known.
#### How?
Migrate your app one major version at a time, while referring to Electron's
[Breaking Changes][breaking-changes] document to see if any code needs to
be updated.
### 17. Validate the `sender` of all IPC messages
You should always validate incoming IPC messages `sender` property to ensure you
aren't performing actions or sending information to untrusted renderers.
#### Why?
All Web Frames can in theory send IPC messages to the main process, including
iframes and child windows in some scenarios. If you have an IPC message that returns
user data to the sender via `event.reply` or performs privileged actions that the renderer
can't natively, you should ensure you aren't listening to third party web frames.
You should be validating the `sender` of **all** IPC messages by default.
#### How?
```js title='main.js (Main Process)'
// Bad
ipcMain.handle('get-secrets', () => {
return getSecrets();
});
// Good
ipcMain.handle('get-secrets', (e) => {
if (!validateSender(e.senderFrame)) return null;
return getSecrets();
});
function validateSender(frame) {
// Value the host of the URL using an actual URL parser and an allowlist
if ((new URL(frame.url)).host === 'electronjs.org') return true;
return false;
}

### Electron Version
18.0.3 (also 18.0.0-beta.1, 19.0.0-alpha.1, 20.0.0-nightly.20220411)
### What operating system are you using?
Windows
### Operating System Version
Windows 11 Pro version 21H2 build 22000.593
### What arch are you using?
x64
### Last Known Working Electron version
17.4.0 (also 18.0.0-alpha.5)
### Expected Behavior
1. Press <kbd>⊞ Win</kbd>+<kbd>Ctrl</kbd>+<kbd>Enter</kbd> to start Windows Narrator.
2. Start [this fiddle](https://gist.github.com/4d0c8b4e45baa84cc152ef7a545dcd98), which just displays `<img src="https://…/icon.png" />`.
3. Electron should not crash.
### Actual Behavior
3. Electron crashes on start.
### Testcase Gist URL
https://gist.github.com/4d0c8b4e45baa84cc152ef7a545dcd98
### Additional Information
I believe this is the crash that was supposed to be fixed by
- #33614
but although that was backported in 18.0.2 (#33616), the crash is evidently not fixed.

### Electron Version
19.0.0-alpha.1
### What operating system are you using?
macOS
### Operating System Version
12.3.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
seems no
### Expected Behavior
the code on below shold not throw ENOENT error because the `ping` command is in `/sbin/ping`
```js
require("child_process").spawn(`./ping`, ["google.com"], {
cwd: "/sbin",
});
```
### Actual Behavior
```js
equire("child_process").spawn(`./ping`, ["google.com"], {
cwd: "/sbin",
});
```
the code above failed and the `ping` process is running in background..
then I try to join cwd with command like this:
```js
require("child_process").spawn(`/sbin/ping`, ["google.com"]);
```
and it works

### Electron Version
19.0.0-alpha.1
### What operating system are you using?
macOS
### Operating System Version
12.3.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
seems no
### Expected Behavior
the code on below shold not throw ENOENT error because the `ping` command is in `/sbin/ping`
```js
require("child_process").spawn(`./ping`, ["google.com"], {
cwd: "/sbin",
});
```
### Actual Behavior
```js
equire("child_process").spawn(`./ping`, ["google.com"], {
cwd: "/sbin",
});
```
the code above failed and the `ping` process is running in background..
then I try to join cwd with command like this:
```js
require("child_process").spawn(`/sbin/ping`, ["google.com"]);
```
and it works

# app
> Control your application's event lifecycle.
Process: [Main](../glossary.md#main-process)
The following example shows how to quit the application when the last window is
closed:
```javascript
const { app } = require('electron')
app.on('window-all-closed', () => {
app.quit()
})
```
## Events
The `app` object emits the following events:
### Event: 'will-finish-launching'
Emitted when the application has finished basic startup. On Windows and Linux,
the `will-finish-launching` event is the same as the `ready` event; on macOS,
this event represents the `applicationWillFinishLaunching` notification of
`NSApplication`. You would usually set up listeners for the `open-file` and
`open-url` events here, and start the crash reporter and auto updater.
In most cases, you should do everything in the `ready` event handler.
### Event: 'ready'
Returns:
* `event` Event
* `launchInfo` Record<string, any> | [NotificationResponse](structures/notification-response.md) _macOS_
Emitted once, when Electron has finished initializing. On macOS, `launchInfo`
holds the `userInfo` of the [`NSUserNotification`](https://developer.apple.com/documentation/foundation/nsusernotification)
or information from [`UNNotificationResponse`](https://developer.apple.com/documentation/usernotifications/unnotificationresponse)
that was used to open the application, if it was launched from Notification Center.
You can also call `app.isReady()` to check if this event has already fired and `app.whenReady()`
to get a Promise that is fulfilled when Electron is initialized.
### Event: 'window-all-closed'
Emitted when all windows have been closed.
If you do not subscribe to this event and all windows are closed, the default
behavior is to quit the app; however, if you subscribe, you control whether the
app quits or not. If the user pressed `Cmd + Q`, or the developer called
`app.quit()`, Electron will first try to close all the windows and then emit the
`will-quit` event, and in this case the `window-all-closed` event would not be
emitted.
### Event: 'before-quit'
Returns:
* `event` Event
Emitted before the application starts closing its windows.
Calling `event.preventDefault()` will prevent the default behavior, which is
terminating the application.
**Note:** If application quit was initiated by `autoUpdater.quitAndInstall()`,
then `before-quit` is emitted *after* emitting `close` event on all windows and
closing them.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'will-quit'
Returns:
* `event` Event
Emitted when all windows have been closed and the application will quit.
Calling `event.preventDefault()` will prevent the default behavior, which is
terminating the application.
See the description of the `window-all-closed` event for the differences between
the `will-quit` and `window-all-closed` events.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'quit'
Returns:
* `event` Event
* `exitCode` Integer
Emitted when the application is quitting.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'open-file' _macOS_
Returns:
* `event` Event
* `path` string
Emitted when the user wants to open a file with the application. The `open-file`
event is usually emitted when the application is already open and the OS wants
to reuse the application to open the file. `open-file` is also emitted when a
file is dropped onto the dock and the application is not yet running. Make sure
to listen for the `open-file` event very early in your application startup to
handle this case (even before the `ready` event is emitted).
You should call `event.preventDefault()` if you want to handle this event.
On Windows, you have to parse `process.argv` (in the main process) to get the
filepath.
### Event: 'open-url' _macOS_
Returns:
* `event` Event
* `url` string
Emitted when the user wants to open a URL with the application. Your application's
`Info.plist` file must define the URL scheme within the `CFBundleURLTypes` key, and
set `NSPrincipalClass` to `AtomApplication`.
You should call `event.preventDefault()` if you want to handle this event.
### Event: 'activate' _macOS_
Returns:
* `event` Event
* `hasVisibleWindows` boolean
Emitted when the application is activated. Various actions can trigger
this event, such as launching the application for the first time, attempting
to re-launch the application when it's already running, or clicking on the
application's dock or taskbar icon.
### Event: 'did-become-active' _macOS_
Returns:
* `event` Event
Emitted when mac application become active. Difference from `activate` event is
that `did-become-active` is emitted every time the app becomes active, not only
when Dock icon is clicked or application is re-launched.
### Event: 'continue-activity' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity on
another device.
* `details` Object
* `webpageURL` string (optional) - A string identifying the URL of the webpage accessed by the activity on another device, if available.
Emitted during [Handoff][handoff] when an activity from a different device wants
to be resumed. You should call `event.preventDefault()` if you want to handle
this event.
A user activity can be continued only in an app that has the same developer Team
ID as the activity's source app and that supports the activity's type.
Supported activity types are specified in the app's `Info.plist` under the
`NSUserActivityTypes` key.
### Event: 'will-continue-activity' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
Emitted during [Handoff][handoff] before an activity from a different device wants
to be resumed. You should call `event.preventDefault()` if you want to handle
this event.
### Event: 'continue-activity-error' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `error` string - A string with the error's localized description.
Emitted during [Handoff][handoff] when an activity from a different device
fails to be resumed.
### Event: 'activity-was-continued' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity.
Emitted during [Handoff][handoff] after an activity from this device was successfully
resumed on another one.
### Event: 'update-activity-state' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity.
Emitted when [Handoff][handoff] is about to be resumed on another device. If you need to update the state to be transferred, you should call `event.preventDefault()` immediately, construct a new `userInfo` dictionary and call `app.updateCurrentActivity()` in a timely manner. Otherwise, the operation will fail and `continue-activity-error` will be called.
### Event: 'new-window-for-tab' _macOS_
Returns:
* `event` Event
Emitted when the user clicks the native macOS new tab button. The new
tab button is only visible if the current `BrowserWindow` has a
`tabbingIdentifier`
### Event: 'browser-window-blur'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a [browserWindow](browser-window.md) gets blurred.
### Event: 'browser-window-focus'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a [browserWindow](browser-window.md) gets focused.
### Event: 'browser-window-created'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a new [browserWindow](browser-window.md) is created.
### Event: 'web-contents-created'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
Emitted when a new [webContents](web-contents.md) is created.
### Event: 'certificate-error'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `url` string
* `error` string - The error code
* `certificate` [Certificate](structures/certificate.md)
* `callback` Function
* `isTrusted` boolean - Whether to consider the certificate as trusted
* `isMainFrame` boolean
Emitted when failed to verify the `certificate` for `url`, to trust the
certificate you should prevent the default behavior with
`event.preventDefault()` and call `callback(true)`.
```javascript
const { app } = require('electron')
app.on('certificate-error', (event, webContents, url, error, certificate, callback) => {
if (url === 'https://github.com') {
// Verification logic.
event.preventDefault()
callback(true)
} else {
callback(false)
}
})
```
### Event: 'select-client-certificate'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `url` URL
* `certificateList` [Certificate[]](structures/certificate.md)
* `callback` Function
* `certificate` [Certificate](structures/certificate.md) (optional)
Emitted when a client certificate is requested.
The `url` corresponds to the navigation entry requesting the client certificate
and `callback` can be called with an entry filtered from the list. Using
`event.preventDefault()` prevents the application from using the first
certificate from the store.
```javascript
const { app } = require('electron')
app.on('select-client-certificate', (event, webContents, url, list, callback) => {
event.preventDefault()
callback(list[0])
})
```
### Event: 'login'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `authenticationResponseDetails` Object
* `url` URL
* `authInfo` Object
* `isProxy` boolean
* `scheme` string
* `host` string
* `port` Integer
* `realm` string
* `callback` Function
* `username` string (optional)
* `password` string (optional)
Emitted when `webContents` wants to do basic auth.
The default behavior is to cancel all authentications. To override this you
should prevent the default behavior with `event.preventDefault()` and call
`callback(username, password)` with the credentials.
```javascript
const { app } = require('electron')
app.on('login', (event, webContents, details, authInfo, callback) => {
event.preventDefault()
callback('username', 'secret')
})
```
If `callback` is called without a username or password, the authentication
request will be cancelled and the authentication error will be returned to the
page.
### Event: 'gpu-info-update'
Emitted whenever there is a GPU info update.
### Event: 'gpu-process-crashed' _Deprecated_
Returns:
* `event` Event
* `killed` boolean
Emitted when the GPU process crashes or is killed.
**Deprecated:** This event is superceded by the `child-process-gone` event
which contains more information about why the child 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: 'renderer-process-crashed' _Deprecated_
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `killed` boolean
Emitted when the renderer process of `webContents` 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
* `webContents` [WebContents](web-contents.md)
* `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: 'child-process-gone'
Returns:
* `event` Event
* `details` Object
* `type` string - Process type. One of the following values:
* `Utility`
* `Zygote`
* `Sandbox helper`
* `GPU`
* `Pepper Plugin`
* `Pepper Plugin Broker`
* `Unknown`
* `reason` string - The reason the child 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` number - The exit code for the process
(e.g. status from waitpid if on posix, from GetExitCodeProcess on Windows).
* `serviceName` string (optional) - The non-localized name of the process.
* `name` string (optional) - The name of the process.
Examples for utility: `Audio Service`, `Content Decryption Module Service`, `Network Service`, `Video Capture`, etc.
Emitted when the child process unexpectedly disappears. This is normally
because it was crashed or killed. It does not include renderer processes.
### Event: 'accessibility-support-changed' _macOS_ _Windows_
Returns:
* `event` Event
* `accessibilitySupportEnabled` boolean - `true` when Chrome's accessibility
support is enabled, `false` otherwise.
Emitted when Chrome's accessibility support changes. This event fires when
assistive technologies, such as screen readers, are enabled or disabled.
See https://www.chromium.org/developers/design-documents/accessibility for more
details.
### Event: 'session-created'
Returns:
* `session` [Session](session.md)
Emitted when Electron has created a new `session`.
```javascript
const { app } = require('electron')
app.on('session-created', (session) => {
console.log(session)
})
```
### Event: 'second-instance'
Returns:
* `event` Event
* `argv` string[] - An array of the second instance's command line arguments
* `workingDirectory` string - The second instance's working directory
* `additionalData` unknown - A JSON object of additional data passed from the second instance
* `ackCallback` unknown - A function that can be used to send data back to the second instance
This event will be emitted inside the primary instance of your application
when a second instance has been executed and calls `app.requestSingleInstanceLock()`.
`argv` is an Array of the second instance's command line arguments,
and `workingDirectory` is its current working directory. Usually
applications respond to this by making their primary window focused and
non-minimized.
**Note:** If the second instance is started by a different user than the first, the `argv` array will not include the arguments.
**Note:** `ackCallback` allows the user to send data back to the
second instance during the `app.requestSingleInstanceLock()` flow.
This callback can be used for cases where the second instance
needs to obtain additional information from the first instance
before quitting.
Currently, the limit on the message size is kMaxMessageLength,
or around 32kB. To be safe, keep the amount of data passed to 31kB at most.
In order to call the callback, `event.preventDefault()` must be called, first.
If the callback is not called in either case, `null` will be sent back.
If `event.preventDefault()` is not called, but `ackCallback` is called
by the user in the event, then the behaviour is undefined.
This event is guaranteed to be emitted after the `ready` event of `app`
gets emitted.
**Note:** Extra command line arguments might be added by Chromium,
such as `--original-process-start-time`.
### Event: 'first-instance-ack'
Returns:
* `event` Event
* `additionalData` unknown - A JSON object of additional data passed from the first instance, in response to the first instance's `second-instance` event.
This event will be emitted within the second instance during the call to `app.requestSingleInstanceLock()`, when the first instance calls the `ackCallback` provided by the `second-instance` event handler.
## Methods
The `app` object has the following methods:
**Note:** Some methods are only available on specific operating systems and are
labeled as such.
### `app.quit()`
Try to close all windows. The `before-quit` event will be emitted first. If all
windows are successfully closed, the `will-quit` event will be emitted and by
default the application will terminate.
This method guarantees that all `beforeunload` and `unload` event handlers are
correctly executed. It is possible that a window cancels the quitting by
returning `false` in the `beforeunload` event handler.
### `app.exit([exitCode])`
* `exitCode` Integer (optional)
Exits immediately with `exitCode`. `exitCode` defaults to 0.
All windows will be closed immediately without asking the user, and the `before-quit`
and `will-quit` events will not be emitted.
### `app.relaunch([options])`
* `options` Object (optional)
* `args` string[] (optional)
* `execPath` string (optional)
Relaunches the app when current instance exits.
By default, the new instance will use the same working directory and command line
arguments with current instance. When `args` is specified, the `args` will be
passed as command line arguments instead. When `execPath` is specified, the
`execPath` will be executed for relaunch instead of current app.
Note that this method does not quit the app when executed, you have to call
`app.quit` or `app.exit` after calling `app.relaunch` to make the app restart.
When `app.relaunch` is called for multiple times, multiple instances will be
started after current instance exited.
An example of restarting current instance immediately and adding a new command
line argument to the new instance:
```javascript
const { app } = require('electron')
app.relaunch({ args: process.argv.slice(1).concat(['--relaunch']) })
app.exit(0)
```
### `app.isReady()`
Returns `boolean` - `true` if Electron has finished initializing, `false` otherwise.
See also `app.whenReady()`.
### `app.whenReady()`
Returns `Promise<void>` - fulfilled when Electron is initialized.
May be used as a convenient alternative to checking `app.isReady()`
and subscribing to the `ready` event if the app is not ready yet.
### `app.focus([options])`
* `options` Object (optional)
* `steal` boolean _macOS_ - Make the receiver the active app even if another app is
currently active.
On Linux, focuses on the first visible window. On macOS, makes the application
the active app. On Windows, focuses on the application's first window.
You should seek to use the `steal` option as sparingly as possible.
### `app.hide()` _macOS_
Hides all application windows without minimizing them.
### `app.isHidden()` _macOS_
Returns `boolean` - `true` if the application—including all of its windows—is hidden (e.g. with `Command-H`), `false` otherwise.
### `app.show()` _macOS_
Shows application windows after they were hidden. Does not automatically focus
them.
### `app.setAppLogsPath([path])`
* `path` string (optional) - A custom path for your logs. Must be absolute.
Sets or creates a directory your app's logs which can then be manipulated with `app.getPath()` or `app.setPath(pathName, newPath)`.
Calling `app.setAppLogsPath()` without a `path` parameter will result in this directory being set to `~/Library/Logs/YourAppName` on _macOS_, and inside the `userData` directory on _Linux_ and _Windows_.
### `app.getAppPath()`
Returns `string` - The current application directory.
### `app.getPath(name)`
* `name` string - You can request the following paths by the name:
* `home` User's home directory.
* `appData` Per-user application data directory, which by default points to:
* `%APPDATA%` on Windows
* `$XDG_CONFIG_HOME` or `~/.config` on Linux
* `~/Library/Application Support` on macOS
* `userData` The directory for storing your app's configuration files, which by
default it is the `appData` directory appended with your app's name.
* `temp` Temporary directory.
* `exe` The current executable file.
* `module` The `libchromiumcontent` library.
* `desktop` The current user's Desktop directory.
* `documents` Directory for a user's "My Documents".
* `downloads` Directory for a user's downloads.
* `music` Directory for a user's music.
* `pictures` Directory for a user's pictures.
* `videos` Directory for a user's videos.
* `recent` Directory for the user's recent files (Windows only).
* `logs` Directory for your app's log folder.
* `crashDumps` Directory where crash dumps are stored.
Returns `string` - A path to a special directory or file associated with `name`. On
failure, an `Error` is thrown.
If `app.getPath('logs')` is called without called `app.setAppLogsPath()` being called first, a default log directory will be created equivalent to calling `app.setAppLogsPath()` without a `path` parameter.
### `app.getFileIcon(path[, options])`
* `path` string
* `options` Object (optional)
* `size` string
* `small` - 16x16
* `normal` - 32x32
* `large` - 48x48 on _Linux_, 32x32 on _Windows_, unsupported on _macOS_.
Returns `Promise<NativeImage>` - fulfilled with the app's icon, which is a [NativeImage](native-image.md).
Fetches a path's associated icon.
On _Windows_, there a 2 kinds of icons:
* Icons associated with certain file extensions, like `.mp3`, `.png`, etc.
* Icons inside the file itself, like `.exe`, `.dll`, `.ico`.
On _Linux_ and _macOS_, icons depend on the application associated with file mime type.
### `app.setPath(name, path)`
* `name` string
* `path` string
Overrides the `path` to a special directory or file associated with `name`.
If the path specifies a directory that does not exist, an `Error` is thrown.
In that case, the directory should be created with `fs.mkdirSync` or similar.
You can only override paths of a `name` defined in `app.getPath`.
By default, web pages' cookies and caches will be stored under the `userData`
directory. If you want to change this location, you have to override the
`userData` path before the `ready` event of the `app` module is emitted.
### `app.getVersion()`
Returns `string` - The version of the loaded application. If no version is found in the
application's `package.json` file, the version of the current bundle or
executable is returned.
### `app.getName()`
Returns `string` - The current application's name, which is the name in the application's
`package.json` file.
Usually the `name` field of `package.json` is a short lowercase name, according
to the npm modules spec. You should usually also specify a `productName`
field, which is your application's full capitalized name, and which will be
preferred over `name` by Electron.
### `app.setName(name)`
* `name` string
Overrides the current application's name.
**Note:** This function overrides the name used internally by Electron; it does not affect the name that the OS uses.
### `app.getLocale()`
Returns `string` - The current application locale, fetched using Chromium's `l10n_util` library.
Possible return values are documented [here](https://source.chromium.org/chromium/chromium/src/+/main:ui/base/l10n/l10n_util.cc).
To set the locale, you'll want to use a command line switch at app startup, which may be found [here](command-line-switches.md).
**Note:** When distributing your packaged app, you have to also ship the
`locales` folder.
**Note:** On Windows, you have to call it after the `ready` events gets emitted.
### `app.getLocaleCountryCode()`
Returns `string` - User operating system's locale two-letter [ISO 3166](https://www.iso.org/iso-3166-country-codes.html) country code. The value is taken from native OS APIs.
**Note:** When unable to detect locale country code, it returns empty string.
### `app.addRecentDocument(path)` _macOS_ _Windows_
* `path` string
Adds `path` to the recent documents list.
This list is managed by the OS. On Windows, you can visit the list from the task
bar, and on macOS, you can visit it from dock menu.
### `app.clearRecentDocuments()` _macOS_ _Windows_
Clears the recent documents list.
### `app.setAsDefaultProtocolClient(protocol[, path, args])`
* `protocol` string - The name of your protocol, without `://`. For example,
if you want your app to handle `electron://` links, call this method with
`electron` as the parameter.
* `path` string (optional) _Windows_ - The path to the Electron executable.
Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Arguments passed to the executable.
Defaults to an empty array
Returns `boolean` - Whether the call succeeded.
Sets the current executable as the default handler for a protocol (aka URI
scheme). It allows you to integrate your app deeper into the operating system.
Once registered, all links with `your-protocol://` will be opened with the
current executable. The whole link, including protocol, will be passed to your
application as a parameter.
**Note:** On macOS, you can only register protocols that have been added to
your app's `info.plist`, which cannot be modified at runtime. However, you can
change the file during build time via [Electron Forge][electron-forge],
[Electron Packager][electron-packager], or by editing `info.plist` with a text
editor. Please refer to [Apple's documentation][CFBundleURLTypes] for details.
**Note:** In a Windows Store environment (when packaged as an `appx`) this API
will return `true` for all calls but the registry key it sets won't be accessible
by other applications. In order to register your Windows Store application
as a default protocol handler you must [declare the protocol in your manifest](https://docs.microsoft.com/en-us/uwp/schemas/appxpackage/uapmanifestschema/element-uap-protocol).
The API uses the Windows Registry and `LSSetDefaultHandlerForURLScheme` internally.
### `app.removeAsDefaultProtocolClient(protocol[, path, args])` _macOS_ _Windows_
* `protocol` string - The name of your protocol, without `://`.
* `path` string (optional) _Windows_ - Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Defaults to an empty array
Returns `boolean` - Whether the call succeeded.
This method checks if the current executable as the default handler for a
protocol (aka URI scheme). If so, it will remove the app as the default handler.
### `app.isDefaultProtocolClient(protocol[, path, args])`
* `protocol` string - The name of your protocol, without `://`.
* `path` string (optional) _Windows_ - Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Defaults to an empty array
Returns `boolean` - Whether the current executable is the default handler for a
protocol (aka URI scheme).
**Note:** On macOS, you can use this method to check if the app has been
registered as the default protocol handler for a protocol. You can also verify
this by checking `~/Library/Preferences/com.apple.LaunchServices.plist` on the
macOS machine. Please refer to
[Apple's documentation][LSCopyDefaultHandlerForURLScheme] for details.
The API uses the Windows Registry and `LSCopyDefaultHandlerForURLScheme` internally.
### `app.getApplicationNameForProtocol(url)`
* `url` string - a URL with the protocol name to check. Unlike the other
methods in this family, this accepts an entire URL, including `://` at a
minimum (e.g. `https://`).
Returns `string` - Name of the application handling the protocol, or an empty
string if there is no handler. For instance, if Electron is the default
handler of the URL, this could be `Electron` on Windows and Mac. However,
don't rely on the precise format which is not guaranteed to remain unchanged.
Expect a different format on Linux, possibly with a `.desktop` suffix.
This method returns the application name of the default handler for the protocol
(aka URI scheme) of a URL.
### `app.getApplicationInfoForProtocol(url)` _macOS_ _Windows_
* `url` string - a URL with the protocol name to check. Unlike the other
methods in this family, this accepts an entire URL, including `://` at a
minimum (e.g. `https://`).
Returns `Promise<Object>` - Resolve with an object containing the following:
* `icon` NativeImage - the display icon of the app handling the protocol.
* `path` string - installation path of the app handling the protocol.
* `name` string - display name of the app handling the protocol.
This method returns a promise that contains the application name, icon and path of the default handler for the protocol
(aka URI scheme) of a URL.
### `app.setUserTasks(tasks)` _Windows_
* `tasks` [Task[]](structures/task.md) - Array of `Task` objects
Adds `tasks` to the [Tasks][tasks] category of the Jump List on Windows.
`tasks` is an array of [`Task`](structures/task.md) objects.
Returns `boolean` - Whether the call succeeded.
**Note:** If you'd like to customize the Jump List even more use
`app.setJumpList(categories)` instead.
### `app.getJumpListSettings()` _Windows_
Returns `Object`:
* `minItems` Integer - The minimum number of items that will be shown in the
Jump List (for a more detailed description of this value see the
[MSDN docs][JumpListBeginListMSDN]).
* `removedItems` [JumpListItem[]](structures/jump-list-item.md) - Array of `JumpListItem`
objects that correspond to items that the user has explicitly removed from custom categories in the
Jump List. These items must not be re-added to the Jump List in the **next**
call to `app.setJumpList()`, Windows will not display any custom category
that contains any of the removed items.
### `app.setJumpList(categories)` _Windows_
* `categories` [JumpListCategory[]](structures/jump-list-category.md) | `null` - Array of `JumpListCategory` objects.
Sets or removes a custom Jump List for the application, and returns one of the
following strings:
* `ok` - Nothing went wrong.
* `error` - One or more errors occurred, enable runtime logging to figure out
the likely cause.
* `invalidSeparatorError` - An attempt was made to add a separator to a
custom category in the Jump List. Separators are only allowed in the
standard `Tasks` category.
* `fileTypeRegistrationError` - An attempt was made to add a file link to
the Jump List for a file type the app isn't registered to handle.
* `customCategoryAccessDeniedError` - Custom categories can't be added to the
Jump List due to user privacy or group policy settings.
If `categories` is `null` the previously set custom Jump List (if any) will be
replaced by the standard Jump List for the app (managed by Windows).
**Note:** If a `JumpListCategory` object has neither the `type` nor the `name`
property set then its `type` is assumed to be `tasks`. If the `name` property
is set but the `type` property is omitted then the `type` is assumed to be
`custom`.
**Note:** Users can remove items from custom categories, and Windows will not
allow a removed item to be added back into a custom category until **after**
the next successful call to `app.setJumpList(categories)`. Any attempt to
re-add a removed item to a custom category earlier than that will result in the
entire custom category being omitted from the Jump List. The list of removed
items can be obtained using `app.getJumpListSettings()`.
**Note:** The maximum length of a Jump List item's `description` property is
260 characters. Beyond this limit, the item will not be added to the Jump
List, nor will it be displayed.
Here's a very simple example of creating a custom Jump List:
```javascript
const { app } = require('electron')
app.setJumpList([
{
type: 'custom',
name: 'Recent Projects',
items: [
{ type: 'file', path: 'C:\\Projects\\project1.proj' },
{ type: 'file', path: 'C:\\Projects\\project2.proj' }
]
},
{ // has a name so `type` is assumed to be "custom"
name: 'Tools',
items: [
{
type: 'task',
title: 'Tool A',
program: process.execPath,
args: '--run-tool-a',
icon: process.execPath,
iconIndex: 0,
description: 'Runs Tool A'
},
{
type: 'task',
title: 'Tool B',
program: process.execPath,
args: '--run-tool-b',
icon: process.execPath,
iconIndex: 0,
description: 'Runs Tool B'
}
]
},
{ type: 'frequent' },
{ // has no name and no type so `type` is assumed to be "tasks"
items: [
{
type: 'task',
title: 'New Project',
program: process.execPath,
args: '--new-project',
description: 'Create a new project.'
},
{ type: 'separator' },
{
type: 'task',
title: 'Recover Project',
program: process.execPath,
args: '--recover-project',
description: 'Recover Project'
}
]
}
])
```
### `app.requestSingleInstanceLock([additionalData])`
* `additionalData` Record<any, any> (optional) - A JSON object containing additional data to send to the first instance.
Returns `boolean`
The return value of this method indicates whether or not this instance of your
application successfully obtained the lock. If it failed to obtain the lock,
you can assume that another instance of your application is already running with
the lock and exit immediately.
I.e. This method returns `true` if your process is the primary instance of your
application and your app should continue loading. It returns `false` if your
process should immediately quit as it has sent its parameters to another
instance that has already acquired the lock.
On macOS, the system enforces single instance automatically when users try to open
a second instance of your app in Finder, and the `open-file` and `open-url`
events will be emitted for that. However when users start your app in command
line, the system's single instance mechanism will be bypassed, and you have to
use this method to ensure single instance.
An example of activating the window of primary instance when a second instance
starts:
```javascript
const { app } = require('electron')
let myWindow = null
app.on('first-instance-ack', (event, additionalData) => {
// Print out the ack received from the first instance.
// Note this event handler must come before the requestSingleInstanceLock call.
// Expected output: '{"myAckKey":"myAckValue"}'
console.log(JSON.stringify(additionalData))
})
const additionalData = { myKey: 'myValue' }
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {
app.on('second-instance', (event, commandLine, workingDirectory, additionalData) => {
// We must call preventDefault if we're sending back data.
event.preventDefault()
// Print out data received from the second instance.
// Expected output: '{"myKey":"myValue"}'
console.log(JSON.stringify(additionalData))
// Someone tried to run a second instance, we should focus our window.
if (myWindow) {
if (myWindow.isMinimized()) myWindow.restore()
myWindow.focus()
}
const ackData = { myAckKey: 'myAckValue' }
ackCallback(ackData)
})
// Create myWindow, load the rest of the app, etc...
app.whenReady().then(() => {
myWindow = createWindow()
})
}
```
### `app.hasSingleInstanceLock()`
Returns `boolean`
This method returns whether or not this instance of your app is currently
holding the single instance lock. You can request the lock with
`app.requestSingleInstanceLock()` and release with
`app.releaseSingleInstanceLock()`
### `app.releaseSingleInstanceLock()`
Releases all locks that were created by `requestSingleInstanceLock`. This will
allow multiple instances of the application to once again run side by side.
### `app.setUserActivity(type, userInfo[, webpageURL])` _macOS_
* `type` string - Uniquely identifies the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` any - App-specific state to store for use by another device.
* `webpageURL` string (optional) - The webpage to load in a browser if no suitable app is
installed on the resuming device. The scheme must be `http` or `https`.
Creates an `NSUserActivity` and sets it as the current activity. The activity
is eligible for [Handoff][handoff] to another device afterward.
### `app.getCurrentActivityType()` _macOS_
Returns `string` - The type of the currently running activity.
### `app.invalidateCurrentActivity()` _macOS_
Invalidates the current [Handoff][handoff] user activity.
### `app.resignCurrentActivity()` _macOS_
Marks the current [Handoff][handoff] user activity as inactive without invalidating it.
### `app.updateCurrentActivity(type, userInfo)` _macOS_
* `type` string - Uniquely identifies the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` any - App-specific state to store for use by another device.
Updates the current activity if its type matches `type`, merging the entries from
`userInfo` into its current `userInfo` dictionary.
### `app.setAppUserModelId(id)` _Windows_
* `id` string
Changes the [Application User Model ID][app-user-model-id] to `id`.
### `app.setActivationPolicy(policy)` _macOS_
* `policy` string - Can be 'regular', 'accessory', or 'prohibited'.
Sets the activation policy for a given app.
Activation policy types:
* 'regular' - The application is an ordinary app that appears in the Dock and may have a user interface.
* 'accessory' - The application doesn’t appear in the Dock and doesn’t have a menu bar, but it may be activated programmatically or by clicking on one of its windows.
* 'prohibited' - The application doesn’t appear in the Dock and may not create windows or be activated.
### `app.importCertificate(options, callback)` _Linux_
* `options` Object
* `certificate` string - Path for the pkcs12 file.
* `password` string - Passphrase for the certificate.
* `callback` Function
* `result` Integer - Result of import.
Imports the certificate in pkcs12 format into the platform certificate store.
`callback` is called with the `result` of import operation, a value of `0`
indicates success while any other value indicates failure according to Chromium [net_error_list](https://source.chromium.org/chromium/chromium/src/+/main:net/base/net_error_list.h).
### `app.configureHostResolver(options)`
* `options` Object
* `enableBuiltInResolver` boolean (optional) - Whether the built-in host
resolver is used in preference to getaddrinfo. When enabled, the built-in
resolver will attempt to use the system's DNS settings to do DNS lookups
itself. Enabled by default on macOS, disabled by default on Windows and
Linux.
* `secureDnsMode` string (optional) - Can be "off", "automatic" or "secure".
Configures the DNS-over-HTTP mode. When "off", no DoH lookups will be
performed. When "automatic", DoH lookups will be performed first if DoH is
available, and insecure DNS lookups will be performed as a fallback. When
"secure", only DoH lookups will be performed. Defaults to "automatic".
* `secureDnsServers` string[] (optional) - A list of DNS-over-HTTP
server templates. See [RFC8484 § 3][] for details on the template format.
Most servers support the POST method; the template for such servers is
simply a URI. Note that for [some DNS providers][doh-providers], the
resolver will automatically upgrade to DoH unless DoH is explicitly
disabled, even if there are no DoH servers provided in this list.
* `enableAdditionalDnsQueryTypes` boolean (optional) - Controls whether additional DNS
query types, e.g. HTTPS (DNS type 65) will be allowed besides the
traditional A and AAAA queries when a request is being made via insecure
DNS. Has no effect on Secure DNS which always allows additional types.
Defaults to true.
Configures host resolution (DNS and DNS-over-HTTPS). By default, the following
resolvers will be used, in order:
1. DNS-over-HTTPS, if the [DNS provider supports it][doh-providers], then
2. the built-in resolver (enabled on macOS only by default), then
3. the system's resolver (e.g. `getaddrinfo`).
This can be configured to either restrict usage of non-encrypted DNS
(`secureDnsMode: "secure"`), or disable DNS-over-HTTPS (`secureDnsMode:
"off"`). It is also possible to enable or disable the built-in resolver.
To disable insecure DNS, you can specify a `secureDnsMode` of `"secure"`. If you do
so, you should make sure to provide a list of DNS-over-HTTPS servers to use, in
case the user's DNS configuration does not include a provider that supports
DoH.
```js
app.configureHostResolver({
secureDnsMode: 'secure',
secureDnsServers: [
'https://cloudflare-dns.com/dns-query'
]
})
```
This API must be called after the `ready` event is emitted.
[doh-providers]: https://source.chromium.org/chromium/chromium/src/+/main:net/dns/public/doh_provider_entry.cc;l=31?q=%22DohProviderEntry::GetList()%22&ss=chromium%2Fchromium%2Fsrc
[RFC8484 § 3]: https://datatracker.ietf.org/doc/html/rfc8484#section-3
### `app.disableHardwareAcceleration()`
Disables hardware acceleration for current app.
This method can only be called before app is ready.
### `app.disableDomainBlockingFor3DAPIs()`
By default, Chromium disables 3D APIs (e.g. WebGL) until restart on a per
domain basis if the GPU processes crashes too frequently. This function
disables that behavior.
This method can only be called before app is ready.
### `app.getAppMetrics()`
Returns [`ProcessMetric[]`](structures/process-metric.md): Array of `ProcessMetric` objects that correspond to memory and CPU usage statistics of all the processes associated with the app.
### `app.getGPUFeatureStatus()`
Returns [`GPUFeatureStatus`](structures/gpu-feature-status.md) - The Graphics Feature Status from `chrome://gpu/`.
**Note:** This information is only usable after the `gpu-info-update` event is emitted.
### `app.getGPUInfo(infoType)`
* `infoType` string - Can be `basic` or `complete`.
Returns `Promise<unknown>`
For `infoType` equal to `complete`:
Promise is fulfilled with `Object` containing all the GPU Information as in [chromium's GPUInfo object](https://chromium.googlesource.com/chromium/src/+/4178e190e9da409b055e5dff469911ec6f6b716f/gpu/config/gpu_info.cc). This includes the version and driver information that's shown on `chrome://gpu` page.
For `infoType` equal to `basic`:
Promise is fulfilled with `Object` containing fewer attributes than when requested with `complete`. Here's an example of basic response:
```js
{
auxAttributes:
{
amdSwitchable: true,
canSupportThreadedTextureMailbox: false,
directComposition: false,
directRendering: true,
glResetNotificationStrategy: 0,
inProcessGpu: true,
initializationTime: 0,
jpegDecodeAcceleratorSupported: false,
optimus: false,
passthroughCmdDecoder: false,
sandboxed: false,
softwareRendering: false,
supportsOverlays: false,
videoDecodeAcceleratorFlags: 0
},
gpuDevice:
[{ active: true, deviceId: 26657, vendorId: 4098 },
{ active: false, deviceId: 3366, vendorId: 32902 }],
machineModelName: 'MacBookPro',
machineModelVersion: '11.5'
}
```
Using `basic` should be preferred if only basic information like `vendorId` or `driverId` is needed.
### `app.setBadgeCount([count])` _Linux_ _macOS_
* `count` Integer (optional) - If a value is provided, set the badge to the provided value otherwise, on macOS, display a plain white dot (e.g. unknown number of notifications). On Linux, if a value is not provided the badge will not display.
Returns `boolean` - Whether the call succeeded.
Sets the counter badge for current app. Setting the count to `0` will hide the
badge.
On macOS, it shows on the dock icon. On Linux, it only works for Unity launcher.
**Note:** Unity launcher requires a `.desktop` file to work. For more information,
please read the [Unity integration documentation][unity-requirement].
### `app.getBadgeCount()` _Linux_ _macOS_
Returns `Integer` - The current value displayed in the counter badge.
### `app.isUnityRunning()` _Linux_
Returns `boolean` - Whether the current desktop environment is Unity launcher.
### `app.getLoginItemSettings([options])` _macOS_ _Windows_
* `options` Object (optional)
* `path` string (optional) _Windows_ - The executable path to compare against.
Defaults to `process.execPath`.
* `args` string[] (optional) _Windows_ - The command-line arguments to compare
against. Defaults to an empty array.
If you provided `path` and `args` options to `app.setLoginItemSettings`, then you
need to pass the same arguments here for `openAtLogin` to be set correctly.
Returns `Object`:
* `openAtLogin` boolean - `true` if the app is set to open at login.
* `openAsHidden` boolean _macOS_ - `true` if the app is set to open as hidden at login.
This setting is not available on [MAS builds][mas-builds].
* `wasOpenedAtLogin` boolean _macOS_ - `true` if the app was opened at login
automatically. This setting is not available on [MAS builds][mas-builds].
* `wasOpenedAsHidden` boolean _macOS_ - `true` if the app was opened as a hidden login
item. This indicates that the app should not open any windows at startup.
This setting is not available on [MAS builds][mas-builds].
* `restoreState` boolean _macOS_ - `true` if the app was opened as a login item that
should restore the state from the previous session. This indicates that the
app should restore the windows that were open the last time the app was
closed. This setting is not available on [MAS builds][mas-builds].
* `executableWillLaunchAtLogin` boolean _Windows_ - `true` if app is set to open at login and its run key is not deactivated. This differs from `openAtLogin` as it ignores the `args` option, this property will be true if the given executable would be launched at login with **any** arguments.
* `launchItems` Object[] _Windows_
* `name` string _Windows_ - name value of a registry entry.
* `path` string _Windows_ - The executable to an app that corresponds to a registry entry.
* `args` string[] _Windows_ - the command-line arguments to pass to the executable.
* `scope` string _Windows_ - one of `user` or `machine`. Indicates whether the registry entry is under `HKEY_CURRENT USER` or `HKEY_LOCAL_MACHINE`.
* `enabled` boolean _Windows_ - `true` if the app registry key is startup approved and therefore shows as `enabled` in Task Manager and Windows settings.
### `app.setLoginItemSettings(settings)` _macOS_ _Windows_
* `settings` Object
* `openAtLogin` boolean (optional) - `true` to open the app at login, `false` to remove
the app as a login item. Defaults to `false`.
* `openAsHidden` boolean (optional) _macOS_ - `true` to open the app as hidden. Defaults to
`false`. The user can edit this setting from the System Preferences so
`app.getLoginItemSettings().wasOpenedAsHidden` should be checked when the app
is opened to know the current value. This setting is not available on [MAS builds][mas-builds].
* `path` string (optional) _Windows_ - The executable to launch at login.
Defaults to `process.execPath`.
* `args` string[] (optional) _Windows_ - The command-line arguments to pass to
the executable. Defaults to an empty array. Take care to wrap paths in
quotes.
* `enabled` boolean (optional) _Windows_ - `true` will change the startup approved registry key and `enable / disable` the App in Task Manager and Windows Settings.
Defaults to `true`.
* `name` string (optional) _Windows_ - value name to write into registry. Defaults to the app's AppUserModelId().
Set the app's login item settings.
To work with Electron's `autoUpdater` on Windows, which uses [Squirrel][Squirrel-Windows],
you'll want to set the launch path to Update.exe, and pass arguments that specify your
application name. For example:
``` javascript
const appFolder = path.dirname(process.execPath)
const updateExe = path.resolve(appFolder, '..', 'Update.exe')
const exeName = path.basename(process.execPath)
app.setLoginItemSettings({
openAtLogin: true,
path: updateExe,
args: [
'--processStart', `"${exeName}"`,
'--process-start-args', `"--hidden"`
]
})
```
### `app.isAccessibilitySupportEnabled()` _macOS_ _Windows_
Returns `boolean` - `true` if Chrome's accessibility support is enabled,
`false` otherwise. This API will return `true` if the use of assistive
technologies, such as screen readers, has been detected. See
https://www.chromium.org/developers/design-documents/accessibility for more
details.
### `app.setAccessibilitySupportEnabled(enabled)` _macOS_ _Windows_
* `enabled` boolean - Enable or disable [accessibility tree](https://developers.google.com/web/fundamentals/accessibility/semantics-builtin/the-accessibility-tree) rendering
Manually enables Chrome's accessibility support, allowing to expose accessibility switch to users in application settings. See [Chromium's accessibility docs](https://www.chromium.org/developers/design-documents/accessibility) for more
details. Disabled by default.
This API must be called after the `ready` event is emitted.
**Note:** Rendering accessibility tree can significantly affect the performance of your app. It should not be enabled by default.
### `app.showAboutPanel()`
Show the app's about panel options. These options can be overridden with `app.setAboutPanelOptions(options)`.
### `app.setAboutPanelOptions(options)`
* `options` Object
* `applicationName` string (optional) - The app's name.
* `applicationVersion` string (optional) - The app's version.
* `copyright` string (optional) - Copyright information.
* `version` string (optional) _macOS_ - The app's build version number.
* `credits` string (optional) _macOS_ _Windows_ - Credit information.
* `authors` string[] (optional) _Linux_ - List of app authors.
* `website` string (optional) _Linux_ - The app's website.
* `iconPath` string (optional) _Linux_ _Windows_ - Path to the app's icon in a JPEG or PNG file format. On Linux, will be shown as 64x64 pixels while retaining aspect ratio.
Set the about panel options. This will override the values defined in the app's `.plist` file on macOS. See the [Apple docs][about-panel-options] for more details. On Linux, values must be set in order to be shown; there are no defaults.
If you do not set `credits` but still wish to surface them in your app, AppKit will look for a file named "Credits.html", "Credits.rtf", and "Credits.rtfd", in that order, in the bundle returned by the NSBundle class method main. The first file found is used, and if none is found, the info area is left blank. See Apple [documentation](https://developer.apple.com/documentation/appkit/nsaboutpaneloptioncredits?language=objc) for more information.
### `app.isEmojiPanelSupported()`
Returns `boolean` - whether or not the current OS version allows for native emoji pickers.
### `app.showEmojiPanel()` _macOS_ _Windows_
Show the platform's native emoji picker.
### `app.startAccessingSecurityScopedResource(bookmarkData)` _mas_
* `bookmarkData` string - The base64 encoded security scoped bookmark data returned by the `dialog.showOpenDialog` or `dialog.showSaveDialog` methods.
Returns `Function` - This function **must** be called once you have finished accessing the security scoped file. If you do not remember to stop accessing the bookmark, [kernel resources will be leaked](https://developer.apple.com/reference/foundation/nsurl/1417051-startaccessingsecurityscopedreso?language=objc) and your app will lose its ability to reach outside the sandbox completely, until your app is restarted.
```js
// Start accessing the file.
const stopAccessingSecurityScopedResource = app.startAccessingSecurityScopedResource(data)
// You can now access the file outside of the sandbox 🎉
// Remember to stop accessing the file once you've finished with it.
stopAccessingSecurityScopedResource()
```
Start accessing a security scoped resource. With this method Electron applications that are packaged for the Mac App Store may reach outside their sandbox to access files chosen by the user. See [Apple's documentation](https://developer.apple.com/library/content/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW16) for a description of how this system works.
### `app.enableSandbox()`
Enables full sandbox mode on the app. This means that all renderers will be launched sandboxed, regardless of the value of the `sandbox` flag in WebPreferences.
This method can only be called before app is ready.
### `app.isInApplicationsFolder()` _macOS_
Returns `boolean` - Whether the application is currently running from the
systems Application folder. Use in combination with `app.moveToApplicationsFolder()`
### `app.moveToApplicationsFolder([options])` _macOS_
* `options` Object (optional)
* `conflictHandler` Function\<boolean> (optional) - A handler for potential conflict in move failure.
* `conflictType` string - The type of move conflict encountered by the handler; can be `exists` or `existsAndRunning`, where `exists` means that an app of the same name is present in the Applications directory and `existsAndRunning` means both that it exists and that it's presently running.
Returns `boolean` - Whether the move was successful. Please note that if
the move is successful, your application will quit and relaunch.
No confirmation dialog will be presented by default. If you wish to allow
the user to confirm the operation, you may do so using the
[`dialog`](dialog.md) API.
**NOTE:** This method throws errors if anything other than the user causes the
move to fail. For instance if the user cancels the authorization dialog, this
method returns false. If we fail to perform the copy, then this method will
throw an error. The message in the error should be informative and tell
you exactly what went wrong.
By default, if an app of the same name as the one being moved exists in the Applications directory and is _not_ running, the existing app will be trashed and the active app moved into its place. If it _is_ running, the pre-existing running app will assume focus and the previously active app will quit itself. This behavior can be changed by providing the optional conflict handler, where the boolean returned by the handler determines whether or not the move conflict is resolved with default behavior. i.e. returning `false` will ensure no further action is taken, returning `true` will result in the default behavior and the method continuing.
For example:
```js
app.moveToApplicationsFolder({
conflictHandler: (conflictType) => {
if (conflictType === 'exists') {
return dialog.showMessageBoxSync({
type: 'question',
buttons: ['Halt Move', 'Continue Move'],
defaultId: 0,
message: 'An app of this name already exists'
}) === 1
}
}
})
```
Would mean that if an app already exists in the user directory, if the user chooses to 'Continue Move' then the function would continue with its default behavior and the existing app will be trashed and the active app moved into its place.
### `app.isSecureKeyboardEntryEnabled()` _macOS_
Returns `boolean` - whether `Secure Keyboard Entry` is enabled.
By default this API will return `false`.
### `app.setSecureKeyboardEntryEnabled(enabled)` _macOS_
* `enabled` boolean - Enable or disable `Secure Keyboard Entry`
Set the `Secure Keyboard Entry` is enabled in your application.
By using this API, important information such as password and other sensitive information can be prevented from being intercepted by other processes.
See [Apple's documentation](https://developer.apple.com/library/archive/technotes/tn2150/_index.html) for more
details.
**Note:** Enable `Secure Keyboard Entry` only when it is needed and disable it when it is no longer needed.
## Properties
### `app.accessibilitySupportEnabled` _macOS_ _Windows_
A `boolean` property that's `true` if Chrome's accessibility support is enabled, `false` otherwise. This property will be `true` if the use of assistive technologies, such as screen readers, has been detected. Setting this property to `true` manually enables Chrome's accessibility support, allowing developers to expose accessibility switch to users in application settings.
See [Chromium's accessibility docs](https://www.chromium.org/developers/design-documents/accessibility) for more details. Disabled by default.
This API must be called after the `ready` event is emitted.
**Note:** Rendering accessibility tree can significantly affect the performance of your app. It should not be enabled by default.
### `app.applicationMenu`
A `Menu | null` property that returns [`Menu`](menu.md) if one has been set and `null` otherwise.
Users can pass a [Menu](menu.md) to set this property.
### `app.badgeCount` _Linux_ _macOS_
An `Integer` property that returns the badge count for current app. Setting the count to `0` will hide the badge.
On macOS, setting this with any nonzero integer shows on the dock icon. On Linux, this property only works for Unity launcher.
**Note:** Unity launcher requires a `.desktop` file to work. For more information,
please read the [Unity integration documentation][unity-requirement].
**Note:** On macOS, you need to ensure that your application has the permission
to display notifications for this property to take effect.
### `app.commandLine` _Readonly_
A [`CommandLine`](./command-line.md) object that allows you to read and manipulate the
command line arguments that Chromium uses.
### `app.dock` _macOS_ _Readonly_
A [`Dock`](./dock.md) `| undefined` object that allows you to perform actions on your app icon in the user's
dock on macOS.
### `app.isPackaged` _Readonly_
A `boolean` property that returns `true` if the app is packaged, `false` otherwise. For many apps, this property can be used to distinguish development and production environments.

### `app.name`
A `string` property that indicates the current application's name, which is the name in the application's `package.json` file.
Usually the `name` field of `package.json` is a short lowercase name, according
to the npm modules spec. You should usually also specify a `productName`
field, which is your application's full capitalized name, and which will be
preferred over `name` by Electron.
### `app.userAgentFallback`
A `string` which is the user agent string Electron will use as a global fallback.
This is the user agent that will be used when no user agent is set at the
`webContents` or `session` level. It is useful for ensuring that your entire
app has the same user agent. Set to a custom value as early as possible
in your app's initialization to ensure that your overridden value is used.
### `app.runningUnderRosettaTranslation` _macOS_ _Readonly_ _Deprecated_
A `boolean` which when `true` indicates that the app is currently running
under the [Rosetta Translator Environment](https://en.wikipedia.org/wiki/Rosetta_(software)).
You can use this property to prompt users to download the arm64 version of
your application when they are running the x64 version under Rosetta
incorrectly.
**Deprecated:** This property is superceded by the `runningUnderARM64Translation`
property which detects when the app is being translated to ARM64 in both macOS
and Windows.
### `app.runningUnderARM64Translation` _Readonly_ _macOS_ _Windows_
A `boolean` which when `true` indicates that the app is currently running under
an ARM64 translator (like the macOS
[Rosetta Translator Environment](https://en.wikipedia.org/wiki/Rosetta_(software))
or Windows [WOW](https://en.wikipedia.org/wiki/Windows_on_Windows)).
You can use this property to prompt users to download the arm64 version of
your application when they are running the x64 version under Rosetta
incorrectly.

# app
> Control your application's event lifecycle.
Process: [Main](../glossary.md#main-process)
The following example shows how to quit the application when the last window is
closed:
```javascript
const { app } = require('electron')
app.on('window-all-closed', () => {
app.quit()
})
```
## Events
The `app` object emits the following events:
### Event: 'will-finish-launching'
Emitted when the application has finished basic startup. On Windows and Linux,
the `will-finish-launching` event is the same as the `ready` event; on macOS,
this event represents the `applicationWillFinishLaunching` notification of
`NSApplication`. You would usually set up listeners for the `open-file` and
`open-url` events here, and start the crash reporter and auto updater.
In most cases, you should do everything in the `ready` event handler.
### Event: 'ready'
Returns:
* `event` Event
* `launchInfo` Record<string, any> | [NotificationResponse](structures/notification-response.md) _macOS_
Emitted once, when Electron has finished initializing. On macOS, `launchInfo`
holds the `userInfo` of the [`NSUserNotification`](https://developer.apple.com/documentation/foundation/nsusernotification)
or information from [`UNNotificationResponse`](https://developer.apple.com/documentation/usernotifications/unnotificationresponse)
that was used to open the application, if it was launched from Notification Center.
You can also call `app.isReady()` to check if this event has already fired and `app.whenReady()`
to get a Promise that is fulfilled when Electron is initialized.
### Event: 'window-all-closed'
Emitted when all windows have been closed.
If you do not subscribe to this event and all windows are closed, the default
behavior is to quit the app; however, if you subscribe, you control whether the
app quits or not. If the user pressed `Cmd + Q`, or the developer called
`app.quit()`, Electron will first try to close all the windows and then emit the
`will-quit` event, and in this case the `window-all-closed` event would not be
emitted.
### Event: 'before-quit'
Returns:
* `event` Event
Emitted before the application starts closing its windows.
Calling `event.preventDefault()` will prevent the default behavior, which is
terminating the application.
**Note:** If application quit was initiated by `autoUpdater.quitAndInstall()`,
then `before-quit` is emitted *after* emitting `close` event on all windows and
closing them.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'will-quit'
Returns:
* `event` Event
Emitted when all windows have been closed and the application will quit.
Calling `event.preventDefault()` will prevent the default behavior, which is
terminating the application.
See the description of the `window-all-closed` event for the differences between
the `will-quit` and `window-all-closed` events.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'quit'
Returns:
* `event` Event
* `exitCode` Integer
Emitted when the application is quitting.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'open-file' _macOS_
Returns:
* `event` Event
* `path` string
Emitted when the user wants to open a file with the application. The `open-file`
event is usually emitted when the application is already open and the OS wants
to reuse the application to open the file. `open-file` is also emitted when a
file is dropped onto the dock and the application is not yet running. Make sure
to listen for the `open-file` event very early in your application startup to
handle this case (even before the `ready` event is emitted).
You should call `event.preventDefault()` if you want to handle this event.
On Windows, you have to parse `process.argv` (in the main process) to get the
filepath.
### Event: 'open-url' _macOS_
Returns:
* `event` Event
* `url` string
Emitted when the user wants to open a URL with the application. Your application's
`Info.plist` file must define the URL scheme within the `CFBundleURLTypes` key, and
set `NSPrincipalClass` to `AtomApplication`.
You should call `event.preventDefault()` if you want to handle this event.
### Event: 'activate' _macOS_
Returns:
* `event` Event
* `hasVisibleWindows` boolean
Emitted when the application is activated. Various actions can trigger
this event, such as launching the application for the first time, attempting
to re-launch the application when it's already running, or clicking on the
application's dock or taskbar icon.
### Event: 'did-become-active' _macOS_
Returns:
* `event` Event
Emitted when mac application become active. Difference from `activate` event is
that `did-become-active` is emitted every time the app becomes active, not only
when Dock icon is clicked or application is re-launched.
### Event: 'continue-activity' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity on
another device.
* `details` Object
* `webpageURL` string (optional) - A string identifying the URL of the webpage accessed by the activity on another device, if available.
Emitted during [Handoff][handoff] when an activity from a different device wants
to be resumed. You should call `event.preventDefault()` if you want to handle
this event.
A user activity can be continued only in an app that has the same developer Team
ID as the activity's source app and that supports the activity's type.
Supported activity types are specified in the app's `Info.plist` under the
`NSUserActivityTypes` key.
### Event: 'will-continue-activity' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
Emitted during [Handoff][handoff] before an activity from a different device wants
to be resumed. You should call `event.preventDefault()` if you want to handle
this event.
### Event: 'continue-activity-error' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `error` string - A string with the error's localized description.
Emitted during [Handoff][handoff] when an activity from a different device
fails to be resumed.
### Event: 'activity-was-continued' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity.
Emitted during [Handoff][handoff] after an activity from this device was successfully
resumed on another one.
### Event: 'update-activity-state' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity.
Emitted when [Handoff][handoff] is about to be resumed on another device. If you need to update the state to be transferred, you should call `event.preventDefault()` immediately, construct a new `userInfo` dictionary and call `app.updateCurrentActivity()` in a timely manner. Otherwise, the operation will fail and `continue-activity-error` will be called.
### Event: 'new-window-for-tab' _macOS_
Returns:
* `event` Event
Emitted when the user clicks the native macOS new tab button. The new
tab button is only visible if the current `BrowserWindow` has a
`tabbingIdentifier`
### Event: 'browser-window-blur'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a [browserWindow](browser-window.md) gets blurred.
### Event: 'browser-window-focus'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a [browserWindow](browser-window.md) gets focused.
### Event: 'browser-window-created'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a new [browserWindow](browser-window.md) is created.
### Event: 'web-contents-created'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
Emitted when a new [webContents](web-contents.md) is created.
### Event: 'certificate-error'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `url` string
* `error` string - The error code
* `certificate` [Certificate](structures/certificate.md)
* `callback` Function
* `isTrusted` boolean - Whether to consider the certificate as trusted
* `isMainFrame` boolean
Emitted when failed to verify the `certificate` for `url`, to trust the
certificate you should prevent the default behavior with
`event.preventDefault()` and call `callback(true)`.
```javascript
const { app } = require('electron')
app.on('certificate-error', (event, webContents, url, error, certificate, callback) => {
if (url === 'https://github.com') {
// Verification logic.
event.preventDefault()
callback(true)
} else {
callback(false)
}
})
```
### Event: 'select-client-certificate'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `url` URL
* `certificateList` [Certificate[]](structures/certificate.md)
* `callback` Function
* `certificate` [Certificate](structures/certificate.md) (optional)
Emitted when a client certificate is requested.
The `url` corresponds to the navigation entry requesting the client certificate
and `callback` can be called with an entry filtered from the list. Using
`event.preventDefault()` prevents the application from using the first
certificate from the store.
```javascript
const { app } = require('electron')
app.on('select-client-certificate', (event, webContents, url, list, callback) => {
event.preventDefault()
callback(list[0])
})
```
### Event: 'login'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `authenticationResponseDetails` Object
* `url` URL
* `authInfo` Object
* `isProxy` boolean
* `scheme` string
* `host` string
* `port` Integer
* `realm` string
* `callback` Function
* `username` string (optional)
* `password` string (optional)
Emitted when `webContents` wants to do basic auth.
The default behavior is to cancel all authentications. To override this you
should prevent the default behavior with `event.preventDefault()` and call
`callback(username, password)` with the credentials.
```javascript
const { app } = require('electron')
app.on('login', (event, webContents, details, authInfo, callback) => {
event.preventDefault()
callback('username', 'secret')
})
```
If `callback` is called without a username or password, the authentication
request will be cancelled and the authentication error will be returned to the
page.
### Event: 'gpu-info-update'
Emitted whenever there is a GPU info update.
### Event: 'gpu-process-crashed' _Deprecated_
Returns:
* `event` Event
* `killed` boolean
Emitted when the GPU process crashes or is killed.
**Deprecated:** This event is superceded by the `child-process-gone` event
which contains more information about why the child 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: 'renderer-process-crashed' _Deprecated_
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `killed` boolean
Emitted when the renderer process of `webContents` 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
* `webContents` [WebContents](web-contents.md)
* `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: 'child-process-gone'
Returns:
* `event` Event
* `details` Object
* `type` string - Process type. One of the following values:
* `Utility`
* `Zygote`
* `Sandbox helper`
* `GPU`
* `Pepper Plugin`
* `Pepper Plugin Broker`
* `Unknown`
* `reason` string - The reason the child 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` number - The exit code for the process
(e.g. status from waitpid if on posix, from GetExitCodeProcess on Windows).
* `serviceName` string (optional) - The non-localized name of the process.
* `name` string (optional) - The name of the process.
Examples for utility: `Audio Service`, `Content Decryption Module Service`, `Network Service`, `Video Capture`, etc.
Emitted when the child process unexpectedly disappears. This is normally
because it was crashed or killed. It does not include renderer processes.
### Event: 'accessibility-support-changed' _macOS_ _Windows_
Returns:
* `event` Event
* `accessibilitySupportEnabled` boolean - `true` when Chrome's accessibility
support is enabled, `false` otherwise.
Emitted when Chrome's accessibility support changes. This event fires when
assistive technologies, such as screen readers, are enabled or disabled.
See https://www.chromium.org/developers/design-documents/accessibility for more
details.
### Event: 'session-created'
Returns:
* `session` [Session](session.md)
Emitted when Electron has created a new `session`.
```javascript
const { app } = require('electron')
app.on('session-created', (session) => {
console.log(session)
})
```
### Event: 'second-instance'
Returns:
* `event` Event
* `argv` string[] - An array of the second instance's command line arguments
* `workingDirectory` string - The second instance's working directory
* `additionalData` unknown - A JSON object of additional data passed from the second instance
* `ackCallback` unknown - A function that can be used to send data back to the second instance
This event will be emitted inside the primary instance of your application
when a second instance has been executed and calls `app.requestSingleInstanceLock()`.
`argv` is an Array of the second instance's command line arguments,
and `workingDirectory` is its current working directory. Usually
applications respond to this by making their primary window focused and
non-minimized.
**Note:** If the second instance is started by a different user than the first, the `argv` array will not include the arguments.
**Note:** `ackCallback` allows the user to send data back to the
second instance during the `app.requestSingleInstanceLock()` flow.
This callback can be used for cases where the second instance
needs to obtain additional information from the first instance
before quitting.
Currently, the limit on the message size is kMaxMessageLength,
or around 32kB. To be safe, keep the amount of data passed to 31kB at most.
In order to call the callback, `event.preventDefault()` must be called, first.
If the callback is not called in either case, `null` will be sent back.
If `event.preventDefault()` is not called, but `ackCallback` is called
by the user in the event, then the behaviour is undefined.
This event is guaranteed to be emitted after the `ready` event of `app`
gets emitted.
**Note:** Extra command line arguments might be added by Chromium,
such as `--original-process-start-time`.
### Event: 'first-instance-ack'
Returns:
* `event` Event
* `additionalData` unknown - A JSON object of additional data passed from the first instance, in response to the first instance's `second-instance` event.
This event will be emitted within the second instance during the call to `app.requestSingleInstanceLock()`, when the first instance calls the `ackCallback` provided by the `second-instance` event handler.
## Methods
The `app` object has the following methods:
**Note:** Some methods are only available on specific operating systems and are
labeled as such.
### `app.quit()`
Try to close all windows. The `before-quit` event will be emitted first. If all
windows are successfully closed, the `will-quit` event will be emitted and by
default the application will terminate.
This method guarantees that all `beforeunload` and `unload` event handlers are
correctly executed. It is possible that a window cancels the quitting by
returning `false` in the `beforeunload` event handler.
### `app.exit([exitCode])`
* `exitCode` Integer (optional)
Exits immediately with `exitCode`. `exitCode` defaults to 0.
All windows will be closed immediately without asking the user, and the `before-quit`
and `will-quit` events will not be emitted.
### `app.relaunch([options])`
* `options` Object (optional)
* `args` string[] (optional)
* `execPath` string (optional)
Relaunches the app when current instance exits.
By default, the new instance will use the same working directory and command line
arguments with current instance. When `args` is specified, the `args` will be
passed as command line arguments instead. When `execPath` is specified, the
`execPath` will be executed for relaunch instead of current app.
Note that this method does not quit the app when executed, you have to call
`app.quit` or `app.exit` after calling `app.relaunch` to make the app restart.
When `app.relaunch` is called for multiple times, multiple instances will be
started after current instance exited.
An example of restarting current instance immediately and adding a new command
line argument to the new instance:
```javascript
const { app } = require('electron')
app.relaunch({ args: process.argv.slice(1).concat(['--relaunch']) })
app.exit(0)
```
### `app.isReady()`
Returns `boolean` - `true` if Electron has finished initializing, `false` otherwise.
See also `app.whenReady()`.
### `app.whenReady()`
Returns `Promise<void>` - fulfilled when Electron is initialized.
May be used as a convenient alternative to checking `app.isReady()`
and subscribing to the `ready` event if the app is not ready yet.
### `app.focus([options])`
* `options` Object (optional)
* `steal` boolean _macOS_ - Make the receiver the active app even if another app is
currently active.
On Linux, focuses on the first visible window. On macOS, makes the application
the active app. On Windows, focuses on the application's first window.
You should seek to use the `steal` option as sparingly as possible.
### `app.hide()` _macOS_
Hides all application windows without minimizing them.
### `app.isHidden()` _macOS_
Returns `boolean` - `true` if the application—including all of its windows—is hidden (e.g. with `Command-H`), `false` otherwise.
### `app.show()` _macOS_
Shows application windows after they were hidden. Does not automatically focus
them.
### `app.setAppLogsPath([path])`
* `path` string (optional) - A custom path for your logs. Must be absolute.
Sets or creates a directory your app's logs which can then be manipulated with `app.getPath()` or `app.setPath(pathName, newPath)`.
Calling `app.setAppLogsPath()` without a `path` parameter will result in this directory being set to `~/Library/Logs/YourAppName` on _macOS_, and inside the `userData` directory on _Linux_ and _Windows_.
### `app.getAppPath()`
Returns `string` - The current application directory.
### `app.getPath(name)`
* `name` string - You can request the following paths by the name:
* `home` User's home directory.
* `appData` Per-user application data directory, which by default points to:
* `%APPDATA%` on Windows
* `$XDG_CONFIG_HOME` or `~/.config` on Linux
* `~/Library/Application Support` on macOS
* `userData` The directory for storing your app's configuration files, which by
default it is the `appData` directory appended with your app's name.
* `temp` Temporary directory.
* `exe` The current executable file.
* `module` The `libchromiumcontent` library.
* `desktop` The current user's Desktop directory.
* `documents` Directory for a user's "My Documents".
* `downloads` Directory for a user's downloads.
* `music` Directory for a user's music.
* `pictures` Directory for a user's pictures.
* `videos` Directory for a user's videos.
* `recent` Directory for the user's recent files (Windows only).
* `logs` Directory for your app's log folder.
* `crashDumps` Directory where crash dumps are stored.
Returns `string` - A path to a special directory or file associated with `name`. On
failure, an `Error` is thrown.
If `app.getPath('logs')` is called without called `app.setAppLogsPath()` being called first, a default log directory will be created equivalent to calling `app.setAppLogsPath()` without a `path` parameter.
### `app.getFileIcon(path[, options])`
* `path` string
* `options` Object (optional)
* `size` string
* `small` - 16x16
* `normal` - 32x32
* `large` - 48x48 on _Linux_, 32x32 on _Windows_, unsupported on _macOS_.
Returns `Promise<NativeImage>` - fulfilled with the app's icon, which is a [NativeImage](native-image.md).
Fetches a path's associated icon.
On _Windows_, there a 2 kinds of icons:
* Icons associated with certain file extensions, like `.mp3`, `.png`, etc.
* Icons inside the file itself, like `.exe`, `.dll`, `.ico`.
On _Linux_ and _macOS_, icons depend on the application associated with file mime type.
### `app.setPath(name, path)`
* `name` string
* `path` string
Overrides the `path` to a special directory or file associated with `name`.
If the path specifies a directory that does not exist, an `Error` is thrown.
In that case, the directory should be created with `fs.mkdirSync` or similar.
You can only override paths of a `name` defined in `app.getPath`.
By default, web pages' cookies and caches will be stored under the `userData`
directory. If you want to change this location, you have to override the
`userData` path before the `ready` event of the `app` module is emitted.
### `app.getVersion()`
Returns `string` - The version of the loaded application. If no version is found in the
application's `package.json` file, the version of the current bundle or
executable is returned.
### `app.getName()`
Returns `string` - The current application's name, which is the name in the application's
`package.json` file.
Usually the `name` field of `package.json` is a short lowercase name, according
to the npm modules spec. You should usually also specify a `productName`
field, which is your application's full capitalized name, and which will be
preferred over `name` by Electron.
### `app.setName(name)`
* `name` string
Overrides the current application's name.
**Note:** This function overrides the name used internally by Electron; it does not affect the name that the OS uses.
### `app.getLocale()`
Returns `string` - The current application locale, fetched using Chromium's `l10n_util` library.
Possible return values are documented [here](https://source.chromium.org/chromium/chromium/src/+/main:ui/base/l10n/l10n_util.cc).
To set the locale, you'll want to use a command line switch at app startup, which may be found [here](command-line-switches.md).
**Note:** When distributing your packaged app, you have to also ship the
`locales` folder.
**Note:** On Windows, you have to call it after the `ready` events gets emitted.
### `app.getLocaleCountryCode()`
Returns `string` - User operating system's locale two-letter [ISO 3166](https://www.iso.org/iso-3166-country-codes.html) country code. The value is taken from native OS APIs.
**Note:** When unable to detect locale country code, it returns empty string.
### `app.addRecentDocument(path)` _macOS_ _Windows_
* `path` string
Adds `path` to the recent documents list.
This list is managed by the OS. On Windows, you can visit the list from the task
bar, and on macOS, you can visit it from dock menu.
### `app.clearRecentDocuments()` _macOS_ _Windows_
Clears the recent documents list.
### `app.setAsDefaultProtocolClient(protocol[, path, args])`
* `protocol` string - The name of your protocol, without `://`. For example,
if you want your app to handle `electron://` links, call this method with
`electron` as the parameter.
* `path` string (optional) _Windows_ - The path to the Electron executable.
Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Arguments passed to the executable.
Defaults to an empty array
Returns `boolean` - Whether the call succeeded.
Sets the current executable as the default handler for a protocol (aka URI
scheme). It allows you to integrate your app deeper into the operating system.
Once registered, all links with `your-protocol://` will be opened with the
current executable. The whole link, including protocol, will be passed to your
application as a parameter.
**Note:** On macOS, you can only register protocols that have been added to
your app's `info.plist`, which cannot be modified at runtime. However, you can
change the file during build time via [Electron Forge][electron-forge],
[Electron Packager][electron-packager], or by editing `info.plist` with a text
editor. Please refer to [Apple's documentation][CFBundleURLTypes] for details.
**Note:** In a Windows Store environment (when packaged as an `appx`) this API
will return `true` for all calls but the registry key it sets won't be accessible
by other applications. In order to register your Windows Store application
as a default protocol handler you must [declare the protocol in your manifest](https://docs.microsoft.com/en-us/uwp/schemas/appxpackage/uapmanifestschema/element-uap-protocol).
The API uses the Windows Registry and `LSSetDefaultHandlerForURLScheme` internally.
### `app.removeAsDefaultProtocolClient(protocol[, path, args])` _macOS_ _Windows_
* `protocol` string - The name of your protocol, without `://`.
* `path` string (optional) _Windows_ - Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Defaults to an empty array
Returns `boolean` - Whether the call succeeded.
This method checks if the current executable as the default handler for a
protocol (aka URI scheme). If so, it will remove the app as the default handler.
### `app.isDefaultProtocolClient(protocol[, path, args])`
* `protocol` string - The name of your protocol, without `://`.
* `path` string (optional) _Windows_ - Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Defaults to an empty array
Returns `boolean` - Whether the current executable is the default handler for a
protocol (aka URI scheme).
**Note:** On macOS, you can use this method to check if the app has been
registered as the default protocol handler for a protocol. You can also verify
this by checking `~/Library/Preferences/com.apple.LaunchServices.plist` on the
macOS machine. Please refer to
[Apple's documentation][LSCopyDefaultHandlerForURLScheme] for details.
The API uses the Windows Registry and `LSCopyDefaultHandlerForURLScheme` internally.
### `app.getApplicationNameForProtocol(url)`
* `url` string - a URL with the protocol name to check. Unlike the other
methods in this family, this accepts an entire URL, including `://` at a
minimum (e.g. `https://`).
Returns `string` - Name of the application handling the protocol, or an empty
string if there is no handler. For instance, if Electron is the default
handler of the URL, this could be `Electron` on Windows and Mac. However,
don't rely on the precise format which is not guaranteed to remain unchanged.
Expect a different format on Linux, possibly with a `.desktop` suffix.
This method returns the application name of the default handler for the protocol
(aka URI scheme) of a URL.
### `app.getApplicationInfoForProtocol(url)` _macOS_ _Windows_
* `url` string - a URL with the protocol name to check. Unlike the other
methods in this family, this accepts an entire URL, including `://` at a
minimum (e.g. `https://`).
Returns `Promise<Object>` - Resolve with an object containing the following:
* `icon` NativeImage - the display icon of the app handling the protocol.
* `path` string - installation path of the app handling the protocol.
* `name` string - display name of the app handling the protocol.
This method returns a promise that contains the application name, icon and path of the default handler for the protocol
(aka URI scheme) of a URL.
### `app.setUserTasks(tasks)` _Windows_
* `tasks` [Task[]](structures/task.md) - Array of `Task` objects
Adds `tasks` to the [Tasks][tasks] category of the Jump List on Windows.
`tasks` is an array of [`Task`](structures/task.md) objects.
Returns `boolean` - Whether the call succeeded.
**Note:** If you'd like to customize the Jump List even more use
`app.setJumpList(categories)` instead.
### `app.getJumpListSettings()` _Windows_
Returns `Object`:
* `minItems` Integer - The minimum number of items that will be shown in the
Jump List (for a more detailed description of this value see the
[MSDN docs][JumpListBeginListMSDN]).
* `removedItems` [JumpListItem[]](structures/jump-list-item.md) - Array of `JumpListItem`
objects that correspond to items that the user has explicitly removed from custom categories in the
Jump List. These items must not be re-added to the Jump List in the **next**
call to `app.setJumpList()`, Windows will not display any custom category
that contains any of the removed items.
### `app.setJumpList(categories)` _Windows_
* `categories` [JumpListCategory[]](structures/jump-list-category.md) | `null` - Array of `JumpListCategory` objects.
Sets or removes a custom Jump List for the application, and returns one of the
following strings:
* `ok` - Nothing went wrong.
* `error` - One or more errors occurred, enable runtime logging to figure out
the likely cause.
* `invalidSeparatorError` - An attempt was made to add a separator to a
custom category in the Jump List. Separators are only allowed in the
standard `Tasks` category.
* `fileTypeRegistrationError` - An attempt was made to add a file link to
the Jump List for a file type the app isn't registered to handle.
* `customCategoryAccessDeniedError` - Custom categories can't be added to the
Jump List due to user privacy or group policy settings.
If `categories` is `null` the previously set custom Jump List (if any) will be
replaced by the standard Jump List for the app (managed by Windows).
**Note:** If a `JumpListCategory` object has neither the `type` nor the `name`
property set then its `type` is assumed to be `tasks`. If the `name` property
is set but the `type` property is omitted then the `type` is assumed to be
`custom`.
**Note:** Users can remove items from custom categories, and Windows will not
allow a removed item to be added back into a custom category until **after**
the next successful call to `app.setJumpList(categories)`. Any attempt to
re-add a removed item to a custom category earlier than that will result in the
entire custom category being omitted from the Jump List. The list of removed
items can be obtained using `app.getJumpListSettings()`.
**Note:** The maximum length of a Jump List item's `description` property is
260 characters. Beyond this limit, the item will not be added to the Jump
List, nor will it be displayed.
Here's a very simple example of creating a custom Jump List:
```javascript
const { app } = require('electron')
app.setJumpList([
{
type: 'custom',
name: 'Recent Projects',
items: [
{ type: 'file', path: 'C:\\Projects\\project1.proj' },
{ type: 'file', path: 'C:\\Projects\\project2.proj' }
]
},
{ // has a name so `type` is assumed to be "custom"
name: 'Tools',
items: [
{
type: 'task',
title: 'Tool A',
program: process.execPath,
args: '--run-tool-a',
icon: process.execPath,
iconIndex: 0,
description: 'Runs Tool A'
},
{
type: 'task',
title: 'Tool B',
program: process.execPath,
args: '--run-tool-b',
icon: process.execPath,
iconIndex: 0,
description: 'Runs Tool B'
}
]
},
{ type: 'frequent' },
{ // has no name and no type so `type` is assumed to be "tasks"
items: [
{
type: 'task',
title: 'New Project',
program: process.execPath,
args: '--new-project',
description: 'Create a new project.'
},
{ type: 'separator' },
{
type: 'task',
title: 'Recover Project',
program: process.execPath,
args: '--recover-project',
description: 'Recover Project'
}
]
}
])
```
### `app.requestSingleInstanceLock([additionalData])`
* `additionalData` Record<any, any> (optional) - A JSON object containing additional data to send to the first instance.
Returns `boolean`
The return value of this method indicates whether or not this instance of your
application successfully obtained the lock. If it failed to obtain the lock,
you can assume that another instance of your application is already running with
the lock and exit immediately.
I.e. This method returns `true` if your process is the primary instance of your
application and your app should continue loading. It returns `false` if your
process should immediately quit as it has sent its parameters to another
instance that has already acquired the lock.
On macOS, the system enforces single instance automatically when users try to open
a second instance of your app in Finder, and the `open-file` and `open-url`
events will be emitted for that. However when users start your app in command
line, the system's single instance mechanism will be bypassed, and you have to
use this method to ensure single instance.
An example of activating the window of primary instance when a second instance
starts:
```javascript
const { app } = require('electron')
let myWindow = null
app.on('first-instance-ack', (event, additionalData) => {
// Print out the ack received from the first instance.
// Note this event handler must come before the requestSingleInstanceLock call.
// Expected output: '{"myAckKey":"myAckValue"}'
console.log(JSON.stringify(additionalData))
})
const additionalData = { myKey: 'myValue' }
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {
app.on('second-instance', (event, commandLine, workingDirectory, additionalData) => {
// We must call preventDefault if we're sending back data.
event.preventDefault()
// Print out data received from the second instance.
// Expected output: '{"myKey":"myValue"}'
console.log(JSON.stringify(additionalData))
// Someone tried to run a second instance, we should focus our window.
if (myWindow) {
if (myWindow.isMinimized()) myWindow.restore()
myWindow.focus()
}
const ackData = { myAckKey: 'myAckValue' }
ackCallback(ackData)
})
// Create myWindow, load the rest of the app, etc...
app.whenReady().then(() => {
myWindow = createWindow()
})
}
```
### `app.hasSingleInstanceLock()`
Returns `boolean`
This method returns whether or not this instance of your app is currently
holding the single instance lock. You can request the lock with
`app.requestSingleInstanceLock()` and release with
`app.releaseSingleInstanceLock()`
### `app.releaseSingleInstanceLock()`
Releases all locks that were created by `requestSingleInstanceLock`. This will
allow multiple instances of the application to once again run side by side.
### `app.setUserActivity(type, userInfo[, webpageURL])` _macOS_
* `type` string - Uniquely identifies the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` any - App-specific state to store for use by another device.
* `webpageURL` string (optional) - The webpage to load in a browser if no suitable app is
installed on the resuming device. The scheme must be `http` or `https`.
Creates an `NSUserActivity` and sets it as the current activity. The activity
is eligible for [Handoff][handoff] to another device afterward.
### `app.getCurrentActivityType()` _macOS_
Returns `string` - The type of the currently running activity.
### `app.invalidateCurrentActivity()` _macOS_
Invalidates the current [Handoff][handoff] user activity.
### `app.resignCurrentActivity()` _macOS_
Marks the current [Handoff][handoff] user activity as inactive without invalidating it.
### `app.updateCurrentActivity(type, userInfo)` _macOS_
* `type` string - Uniquely identifies the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` any - App-specific state to store for use by another device.
Updates the current activity if its type matches `type`, merging the entries from
`userInfo` into its current `userInfo` dictionary.
### `app.setAppUserModelId(id)` _Windows_
* `id` string
Changes the [Application User Model ID][app-user-model-id] to `id`.
### `app.setActivationPolicy(policy)` _macOS_
* `policy` string - Can be 'regular', 'accessory', or 'prohibited'.
Sets the activation policy for a given app.
Activation policy types:
* 'regular' - The application is an ordinary app that appears in the Dock and may have a user interface.
* 'accessory' - The application doesn’t appear in the Dock and doesn’t have a menu bar, but it may be activated programmatically or by clicking on one of its windows.
* 'prohibited' - The application doesn’t appear in the Dock and may not create windows or be activated.
### `app.importCertificate(options, callback)` _Linux_
* `options` Object
* `certificate` string - Path for the pkcs12 file.
* `password` string - Passphrase for the certificate.
* `callback` Function
* `result` Integer - Result of import.
Imports the certificate in pkcs12 format into the platform certificate store.
`callback` is called with the `result` of import operation, a value of `0`
indicates success while any other value indicates failure according to Chromium [net_error_list](https://source.chromium.org/chromium/chromium/src/+/main:net/base/net_error_list.h).
### `app.configureHostResolver(options)`
* `options` Object
* `enableBuiltInResolver` boolean (optional) - Whether the built-in host
resolver is used in preference to getaddrinfo. When enabled, the built-in
resolver will attempt to use the system's DNS settings to do DNS lookups
itself. Enabled by default on macOS, disabled by default on Windows and
Linux.
* `secureDnsMode` string (optional) - Can be "off", "automatic" or "secure".
Configures the DNS-over-HTTP mode. When "off", no DoH lookups will be
performed. When "automatic", DoH lookups will be performed first if DoH is
available, and insecure DNS lookups will be performed as a fallback. When
"secure", only DoH lookups will be performed. Defaults to "automatic".
* `secureDnsServers` string[] (optional) - A list of DNS-over-HTTP
server templates. See [RFC8484 § 3][] for details on the template format.
Most servers support the POST method; the template for such servers is
simply a URI. Note that for [some DNS providers][doh-providers], the
resolver will automatically upgrade to DoH unless DoH is explicitly
disabled, even if there are no DoH servers provided in this list.
* `enableAdditionalDnsQueryTypes` boolean (optional) - Controls whether additional DNS
query types, e.g. HTTPS (DNS type 65) will be allowed besides the
traditional A and AAAA queries when a request is being made via insecure
DNS. Has no effect on Secure DNS which always allows additional types.
Defaults to true.
Configures host resolution (DNS and DNS-over-HTTPS). By default, the following
resolvers will be used, in order:
1. DNS-over-HTTPS, if the [DNS provider supports it][doh-providers], then
2. the built-in resolver (enabled on macOS only by default), then
3. the system's resolver (e.g. `getaddrinfo`).
This can be configured to either restrict usage of non-encrypted DNS
(`secureDnsMode: "secure"`), or disable DNS-over-HTTPS (`secureDnsMode:
"off"`). It is also possible to enable or disable the built-in resolver.
To disable insecure DNS, you can specify a `secureDnsMode` of `"secure"`. If you do
so, you should make sure to provide a list of DNS-over-HTTPS servers to use, in
case the user's DNS configuration does not include a provider that supports
DoH.
```js
app.configureHostResolver({
secureDnsMode: 'secure',
secureDnsServers: [
'https://cloudflare-dns.com/dns-query'
]
})
```
This API must be called after the `ready` event is emitted.
[doh-providers]: https://source.chromium.org/chromium/chromium/src/+/main:net/dns/public/doh_provider_entry.cc;l=31?q=%22DohProviderEntry::GetList()%22&ss=chromium%2Fchromium%2Fsrc
[RFC8484 § 3]: https://datatracker.ietf.org/doc/html/rfc8484#section-3
### `app.disableHardwareAcceleration()`
Disables hardware acceleration for current app.
This method can only be called before app is ready.
### `app.disableDomainBlockingFor3DAPIs()`
By default, Chromium disables 3D APIs (e.g. WebGL) until restart on a per
domain basis if the GPU processes crashes too frequently. This function
disables that behavior.
This method can only be called before app is ready.
### `app.getAppMetrics()`
Returns [`ProcessMetric[]`](structures/process-metric.md): Array of `ProcessMetric` objects that correspond to memory and CPU usage statistics of all the processes associated with the app.
### `app.getGPUFeatureStatus()`
Returns [`GPUFeatureStatus`](structures/gpu-feature-status.md) - The Graphics Feature Status from `chrome://gpu/`.
**Note:** This information is only usable after the `gpu-info-update` event is emitted.
### `app.getGPUInfo(infoType)`
* `infoType` string - Can be `basic` or `complete`.
Returns `Promise<unknown>`
For `infoType` equal to `complete`:
Promise is fulfilled with `Object` containing all the GPU Information as in [chromium's GPUInfo object](https://chromium.googlesource.com/chromium/src/+/4178e190e9da409b055e5dff469911ec6f6b716f/gpu/config/gpu_info.cc). This includes the version and driver information that's shown on `chrome://gpu` page.
For `infoType` equal to `basic`:
Promise is fulfilled with `Object` containing fewer attributes than when requested with `complete`. Here's an example of basic response:
```js
{
auxAttributes:
{
amdSwitchable: true,
canSupportThreadedTextureMailbox: false,
directComposition: false,
directRendering: true,
glResetNotificationStrategy: 0,
inProcessGpu: true,
initializationTime: 0,
jpegDecodeAcceleratorSupported: false,
optimus: false,
passthroughCmdDecoder: false,
sandboxed: false,
softwareRendering: false,
supportsOverlays: false,
videoDecodeAcceleratorFlags: 0
},
gpuDevice:
[{ active: true, deviceId: 26657, vendorId: 4098 },
{ active: false, deviceId: 3366, vendorId: 32902 }],
machineModelName: 'MacBookPro',
machineModelVersion: '11.5'
}
```
Using `basic` should be preferred if only basic information like `vendorId` or `driverId` is needed.
### `app.setBadgeCount([count])` _Linux_ _macOS_
* `count` Integer (optional) - If a value is provided, set the badge to the provided value otherwise, on macOS, display a plain white dot (e.g. unknown number of notifications). On Linux, if a value is not provided the badge will not display.
Returns `boolean` - Whether the call succeeded.
Sets the counter badge for current app. Setting the count to `0` will hide the
badge.
On macOS, it shows on the dock icon. On Linux, it only works for Unity launcher.
**Note:** Unity launcher requires a `.desktop` file to work. For more information,
please read the [Unity integration documentation][unity-requirement].
### `app.getBadgeCount()` _Linux_ _macOS_
Returns `Integer` - The current value displayed in the counter badge.
### `app.isUnityRunning()` _Linux_
Returns `boolean` - Whether the current desktop environment is Unity launcher.
### `app.getLoginItemSettings([options])` _macOS_ _Windows_
* `options` Object (optional)
* `path` string (optional) _Windows_ - The executable path to compare against.
Defaults to `process.execPath`.
* `args` string[] (optional) _Windows_ - The command-line arguments to compare
against. Defaults to an empty array.
If you provided `path` and `args` options to `app.setLoginItemSettings`, then you
need to pass the same arguments here for `openAtLogin` to be set correctly.
Returns `Object`:
* `openAtLogin` boolean - `true` if the app is set to open at login.
* `openAsHidden` boolean _macOS_ - `true` if the app is set to open as hidden at login.
This setting is not available on [MAS builds][mas-builds].
* `wasOpenedAtLogin` boolean _macOS_ - `true` if the app was opened at login
automatically. This setting is not available on [MAS builds][mas-builds].
* `wasOpenedAsHidden` boolean _macOS_ - `true` if the app was opened as a hidden login
item. This indicates that the app should not open any windows at startup.
This setting is not available on [MAS builds][mas-builds].
* `restoreState` boolean _macOS_ - `true` if the app was opened as a login item that
should restore the state from the previous session. This indicates that the
app should restore the windows that were open the last time the app was
closed. This setting is not available on [MAS builds][mas-builds].
* `executableWillLaunchAtLogin` boolean _Windows_ - `true` if app is set to open at login and its run key is not deactivated. This differs from `openAtLogin` as it ignores the `args` option, this property will be true if the given executable would be launched at login with **any** arguments.
* `launchItems` Object[] _Windows_
* `name` string _Windows_ - name value of a registry entry.
* `path` string _Windows_ - The executable to an app that corresponds to a registry entry.
* `args` string[] _Windows_ - the command-line arguments to pass to the executable.
* `scope` string _Windows_ - one of `user` or `machine`. Indicates whether the registry entry is under `HKEY_CURRENT USER` or `HKEY_LOCAL_MACHINE`.
* `enabled` boolean _Windows_ - `true` if the app registry key is startup approved and therefore shows as `enabled` in Task Manager and Windows settings.
### `app.setLoginItemSettings(settings)` _macOS_ _Windows_
* `settings` Object
* `openAtLogin` boolean (optional) - `true` to open the app at login, `false` to remove
the app as a login item. Defaults to `false`.
* `openAsHidden` boolean (optional) _macOS_ - `true` to open the app as hidden. Defaults to
`false`. The user can edit this setting from the System Preferences so
`app.getLoginItemSettings().wasOpenedAsHidden` should be checked when the app
is opened to know the current value. This setting is not available on [MAS builds][mas-builds].
* `path` string (optional) _Windows_ - The executable to launch at login.
Defaults to `process.execPath`.
* `args` string[] (optional) _Windows_ - The command-line arguments to pass to
the executable. Defaults to an empty array. Take care to wrap paths in
quotes.
* `enabled` boolean (optional) _Windows_ - `true` will change the startup approved registry key and `enable / disable` the App in Task Manager and Windows Settings.
Defaults to `true`.
* `name` string (optional) _Windows_ - value name to write into registry. Defaults to the app's AppUserModelId().
Set the app's login item settings.
To work with Electron's `autoUpdater` on Windows, which uses [Squirrel][Squirrel-Windows],
you'll want to set the launch path to Update.exe, and pass arguments that specify your
application name. For example:
``` javascript
const appFolder = path.dirname(process.execPath)
const updateExe = path.resolve(appFolder, '..', 'Update.exe')
const exeName = path.basename(process.execPath)
app.setLoginItemSettings({
openAtLogin: true,
path: updateExe,
args: [
'--processStart', `"${exeName}"`,
'--process-start-args', `"--hidden"`
]
})
```
### `app.isAccessibilitySupportEnabled()` _macOS_ _Windows_
Returns `boolean` - `true` if Chrome's accessibility support is enabled,
`false` otherwise. This API will return `true` if the use of assistive
technologies, such as screen readers, has been detected. See
https://www.chromium.org/developers/design-documents/accessibility for more
details.
### `app.setAccessibilitySupportEnabled(enabled)` _macOS_ _Windows_
* `enabled` boolean - Enable or disable [accessibility tree](https://developers.google.com/web/fundamentals/accessibility/semantics-builtin/the-accessibility-tree) rendering
Manually enables Chrome's accessibility support, allowing to expose accessibility switch to users in application settings. See [Chromium's accessibility docs](https://www.chromium.org/developers/design-documents/accessibility) for more
details. Disabled by default.
This API must be called after the `ready` event is emitted.
**Note:** Rendering accessibility tree can significantly affect the performance of your app. It should not be enabled by default.
### `app.showAboutPanel()`
Show the app's about panel options. These options can be overridden with `app.setAboutPanelOptions(options)`.
### `app.setAboutPanelOptions(options)`
* `options` Object
* `applicationName` string (optional) - The app's name.
* `applicationVersion` string (optional) - The app's version.
* `copyright` string (optional) - Copyright information.
* `version` string (optional) _macOS_ - The app's build version number.
* `credits` string (optional) _macOS_ _Windows_ - Credit information.
* `authors` string[] (optional) _Linux_ - List of app authors.
* `website` string (optional) _Linux_ - The app's website.
* `iconPath` string (optional) _Linux_ _Windows_ - Path to the app's icon in a JPEG or PNG file format. On Linux, will be shown as 64x64 pixels while retaining aspect ratio.
Set the about panel options. This will override the values defined in the app's `.plist` file on macOS. See the [Apple docs][about-panel-options] for more details. On Linux, values must be set in order to be shown; there are no defaults.
If you do not set `credits` but still wish to surface them in your app, AppKit will look for a file named "Credits.html", "Credits.rtf", and "Credits.rtfd", in that order, in the bundle returned by the NSBundle class method main. The first file found is used, and if none is found, the info area is left blank. See Apple [documentation](https://developer.apple.com/documentation/appkit/nsaboutpaneloptioncredits?language=objc) for more information.
### `app.isEmojiPanelSupported()`
Returns `boolean` - whether or not the current OS version allows for native emoji pickers.
### `app.showEmojiPanel()` _macOS_ _Windows_
Show the platform's native emoji picker.
### `app.startAccessingSecurityScopedResource(bookmarkData)` _mas_
* `bookmarkData` string - The base64 encoded security scoped bookmark data returned by the `dialog.showOpenDialog` or `dialog.showSaveDialog` methods.
Returns `Function` - This function **must** be called once you have finished accessing the security scoped file. If you do not remember to stop accessing the bookmark, [kernel resources will be leaked](https://developer.apple.com/reference/foundation/nsurl/1417051-startaccessingsecurityscopedreso?language=objc) and your app will lose its ability to reach outside the sandbox completely, until your app is restarted.
```js
// Start accessing the file.
const stopAccessingSecurityScopedResource = app.startAccessingSecurityScopedResource(data)
// You can now access the file outside of the sandbox 🎉
// Remember to stop accessing the file once you've finished with it.
stopAccessingSecurityScopedResource()
```
Start accessing a security scoped resource. With this method Electron applications that are packaged for the Mac App Store may reach outside their sandbox to access files chosen by the user. See [Apple's documentation](https://developer.apple.com/library/content/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW16) for a description of how this system works.
### `app.enableSandbox()`
Enables full sandbox mode on the app. This means that all renderers will be launched sandboxed, regardless of the value of the `sandbox` flag in WebPreferences.
This method can only be called before app is ready.
### `app.isInApplicationsFolder()` _macOS_
Returns `boolean` - Whether the application is currently running from the
systems Application folder. Use in combination with `app.moveToApplicationsFolder()`
### `app.moveToApplicationsFolder([options])` _macOS_
* `options` Object (optional)
* `conflictHandler` Function\<boolean> (optional) - A handler for potential conflict in move failure.
* `conflictType` string - The type of move conflict encountered by the handler; can be `exists` or `existsAndRunning`, where `exists` means that an app of the same name is present in the Applications directory and `existsAndRunning` means both that it exists and that it's presently running.
Returns `boolean` - Whether the move was successful. Please note that if
the move is successful, your application will quit and relaunch.
No confirmation dialog will be presented by default. If you wish to allow
the user to confirm the operation, you may do so using the
[`dialog`](dialog.md) API.
**NOTE:** This method throws errors if anything other than the user causes the
move to fail. For instance if the user cancels the authorization dialog, this
method returns false. If we fail to perform the copy, then this method will
throw an error. The message in the error should be informative and tell
you exactly what went wrong.
By default, if an app of the same name as the one being moved exists in the Applications directory and is _not_ running, the existing app will be trashed and the active app moved into its place. If it _is_ running, the pre-existing running app will assume focus and the previously active app will quit itself. This behavior can be changed by providing the optional conflict handler, where the boolean returned by the handler determines whether or not the move conflict is resolved with default behavior. i.e. returning `false` will ensure no further action is taken, returning `true` will result in the default behavior and the method continuing.
For example:
```js
app.moveToApplicationsFolder({
conflictHandler: (conflictType) => {
if (conflictType === 'exists') {
return dialog.showMessageBoxSync({
type: 'question',
buttons: ['Halt Move', 'Continue Move'],
defaultId: 0,
message: 'An app of this name already exists'
}) === 1
}
}
})
```
Would mean that if an app already exists in the user directory, if the user chooses to 'Continue Move' then the function would continue with its default behavior and the existing app will be trashed and the active app moved into its place.
### `app.isSecureKeyboardEntryEnabled()` _macOS_
Returns `boolean` - whether `Secure Keyboard Entry` is enabled.
By default this API will return `false`.
### `app.setSecureKeyboardEntryEnabled(enabled)` _macOS_
* `enabled` boolean - Enable or disable `Secure Keyboard Entry`
Set the `Secure Keyboard Entry` is enabled in your application.
By using this API, important information such as password and other sensitive information can be prevented from being intercepted by other processes.
See [Apple's documentation](https://developer.apple.com/library/archive/technotes/tn2150/_index.html) for more
details.
**Note:** Enable `Secure Keyboard Entry` only when it is needed and disable it when it is no longer needed.
## Properties
### `app.accessibilitySupportEnabled` _macOS_ _Windows_
A `boolean` property that's `true` if Chrome's accessibility support is enabled, `false` otherwise. This property will be `true` if the use of assistive technologies, such as screen readers, has been detected. Setting this property to `true` manually enables Chrome's accessibility support, allowing developers to expose accessibility switch to users in application settings.
See [Chromium's accessibility docs](https://www.chromium.org/developers/design-documents/accessibility) for more details. Disabled by default.
This API must be called after the `ready` event is emitted.
**Note:** Rendering accessibility tree can significantly affect the performance of your app. It should not be enabled by default.
### `app.applicationMenu`
A `Menu | null` property that returns [`Menu`](menu.md) if one has been set and `null` otherwise.
Users can pass a [Menu](menu.md) to set this property.
### `app.badgeCount` _Linux_ _macOS_
An `Integer` property that returns the badge count for current app. Setting the count to `0` will hide the badge.
On macOS, setting this with any nonzero integer shows on the dock icon. On Linux, this property only works for Unity launcher.
**Note:** Unity launcher requires a `.desktop` file to work. For more information,
please read the [Unity integration documentation][unity-requirement].
**Note:** On macOS, you need to ensure that your application has the permission
to display notifications for this property to take effect.
### `app.commandLine` _Readonly_
A [`CommandLine`](./command-line.md) object that allows you to read and manipulate the
command line arguments that Chromium uses.
### `app.dock` _macOS_ _Readonly_
A [`Dock`](./dock.md) `| undefined` object that allows you to perform actions on your app icon in the user's
dock on macOS.
### `app.isPackaged` _Readonly_
A `boolean` property that returns `true` if the app is packaged, `false` otherwise. For many apps, this property can be used to distinguish development and production environments.

### `app.name`
A `string` property that indicates the current application's name, which is the name in the application's `package.json` file.
Usually the `name` field of `package.json` is a short lowercase name, according
to the npm modules spec. You should usually also specify a `productName`
field, which is your application's full capitalized name, and which will be
preferred over `name` by Electron.
### `app.userAgentFallback`
A `string` which is the user agent string Electron will use as a global fallback.
This is the user agent that will be used when no user agent is set at the
`webContents` or `session` level. It is useful for ensuring that your entire
app has the same user agent. Set to a custom value as early as possible
in your app's initialization to ensure that your overridden value is used.
### `app.runningUnderRosettaTranslation` _macOS_ _Readonly_ _Deprecated_
A `boolean` which when `true` indicates that the app is currently running
under the [Rosetta Translator Environment](https://en.wikipedia.org/wiki/Rosetta_(software)).
You can use this property to prompt users to download the arm64 version of
your application when they are running the x64 version under Rosetta
incorrectly.
**Deprecated:** This property is superceded by the `runningUnderARM64Translation`
property which detects when the app is being translated to ARM64 in both macOS
and Windows.
### `app.runningUnderARM64Translation` _Readonly_ _macOS_ _Windows_
A `boolean` which when `true` indicates that the app is currently running under
an ARM64 translator (like the macOS
[Rosetta Translator Environment](https://en.wikipedia.org/wiki/Rosetta_(software))
or Windows [WOW](https://en.wikipedia.org/wiki/Windows_on_Windows)).
You can use this property to prompt users to download the arm64 version of
your application when they are running the x64 version under Rosetta
incorrectly.

### Electron Version
17.0.0
### What operating system are you using?
macOS
### Operating System Version
macOS Catalina 10.15.7
### What arch are you using?
x64

[Text version of crash report](https://github.com/electron/electron/files/7987634/crash.report.txt)
### Actual Behavior
Sometimes, after working for a while, the app crashes giving the Apple Problem Report attached.
### Testcase Gist URL
_No response_
### Additional Information
We're hoping to move to Electron 17 ASAP to pick up some Chromium bug fixes. I built an alpha of our application with the new 17.0.0 release yesterday.
The crash behavior isn't predictably reproducible that I know of, although it has happened a few times to this user who is one of the employees of our company. I haven't see in at all in my arm64 version or for the 15 minutes I used our x64 version on my old laptop.

[Bug]: File Selection Dialog Filter Issue on Linux
|
### 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
18.0.4
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 20.0.4
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
File Selection Dialog should show files with the filtered extension, with no need for case match.
### Example:
`*.Foo` files should show up if we set filters for `[{name: 'Foo Files', extensions: ['Foo']}]` or even ``[{name: 'Foo Files', extensions: ['foo']}]`.
### Actual Behavior
File Selection Dialog does not show any files if the Filter contains a mixed case extension string.
### Example:
`*.Foo` files do not show up if we set filters for `[{name: 'Foo Files', extensions: ['Foo']}]` or even ``[{name: 'Foo Files', extensions: ['foo']}]` and any case match setup.
### Testcase Gist URL
https://gist.github.com/047baebf59014c18491c4efdfb75a5f8
### Additional Information
The issue probably come from this [function](https://github.com/electron/electron/blob/main/shell/browser/ui/file_dialog_gtk.cc#L250-L266) (https://github.com/electron/electron/blob/main/shell/browser/ui/file_dialog_gtk.cc#L250-L266) that seems to only check for lowercased or uppercased extensions.
### Example:
`[{name: 'Foo Files', extensions: ['Foo']}]` will only show `*.foo` or `*.FOO` files.
### Gist
In the provided gist, it will ask you to add a `aim-file.Js` file. Please add it. Then run the fiddle. It will open a File Selection Dialog and will not show the `aim-file.Js`. If you change the file type to `All`, that file will show up.

### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 20.0.4
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
File Selection Dialog should show files with the filtered extension, with no need for case match.
### Example:
`*.Foo` files should show up if we set filters for `[{name: 'Foo Files', extensions: ['Foo']}]` or even ``[{name: 'Foo Files', extensions: ['foo']}]`.
### Actual Behavior
File Selection Dialog does not show any files if the Filter contains a mixed case extension string.
### Example:
`*.Foo` files do not show up if we set filters for `[{name: 'Foo Files', extensions: ['Foo']}]` or even ``[{name: 'Foo Files', extensions: ['foo']}]` and any case match setup.
### Testcase Gist URL
https://gist.github.com/047baebf59014c18491c4efdfb75a5f8
### Additional Information
The issue probably come from this [function](https://github.com/electron/electron/blob/main/shell/browser/ui/file_dialog_gtk.cc#L250-L266) (https://github.com/electron/electron/blob/main/shell/browser/ui/file_dialog_gtk.cc#L250-L266) that seems to only check for lowercased or uppercased extensions.
### Example:
`[{name: 'Foo Files', extensions: ['Foo']}]` will only show `*.foo` or `*.FOO` files.
### Gist
In the provided gist, it will ask you to add a `aim-file.Js` file. Please add it. Then run the fiddle. It will open a File Selection Dialog and will not show the `aim-file.Js`. If you change the file type to `All`, that file will show up.

[Bug]: `BrowserWindow`: `isFocused()` returns `true` even after calling `blur()` 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
18.0.3
### What operating system are you using?
macOS
### Operating System Version
macOS Monterey 12.2.1
### What arch are you using?
x64
### Last Known Working Electron version
Unknown, reproduces back to v14.
### Expected Behavior
`isFocused()` should return `false` after `blur()` has been called on it.
### Actual Behavior
It returns `true` instead, hence the assertion error:
```sh
$ npm test
> [email protected] test
> electron test.js
AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
true !== false
at /Users/raisinten/Desktop/temp/project/electron/test.js:10:3 {
generatedMessage: true,
code: 'ERR_ASSERTION',
actual: true,
expected: false,
operator: 'strictEqual'
}
$ echo $?
1
```
### Testcase Gist URL

[Bug]: `BrowserWindow`: `isFocused()` returns `true` even after calling `blur()` 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
18.0.3
### What operating system are you using?
macOS
### Operating System Version
macOS Monterey 12.2.1
### What arch are you using?
x64
### Last Known Working Electron version
Unknown, reproduces back to v14.
### Expected Behavior
`isFocused()` should return `false` after `blur()` has been called on it.
### Actual Behavior
It returns `true` instead, hence the assertion error:
```sh
$ npm test
> [email protected] test
> electron test.js
AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
true !== false
at /Users/raisinten/Desktop/temp/project/electron/test.js:10:3 {
generatedMessage: true,
code: 'ERR_ASSERTION',
actual: true,
expected: false,
operator: 'strictEqual'
}
$ echo $?
1
```
### Testcase Gist URL
https://gist.github.com/RaisinTen/245976064623786f2276dd89d2df0185

[Bug]: `BrowserWindow`: `isFocused()` returns `true` even after calling `blur()` 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
18.0.3
### What operating system are you using?
macOS
### Operating System Version
macOS Monterey 12.2.1
### What arch are you using?
x64
### Last Known Working Electron version
Unknown, reproduces back to v14.
### Expected Behavior
`isFocused()` should return `false` after `blur()` has been called on it.
### Actual Behavior
It returns `true` instead, hence the assertion error:
```sh
$ npm test
> [email protected] test
> electron test.js
AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
true !== false
at /Users/raisinten/Desktop/temp/project/electron/test.js:10:3 {
generatedMessage: true,
code: 'ERR_ASSERTION',
actual: true,
expected: false,
operator: 'strictEqual'
}
$ echo $?
1
```
### Testcase Gist URL
https://gist.github.com/RaisinTen/245976064623786f2276dd89d2df0185

[Bug]: `BrowserWindow`: `isFocused()` returns `true` even after calling `blur()` 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
18.0.3
### What operating system are you using?
macOS
### Operating System Version
macOS Monterey 12.2.1
### What arch are you using?
x64
### Last Known Working Electron version
Unknown, reproduces back to v14.
### Expected Behavior
`isFocused()` should return `false` after `blur()` has been called on it.
### Actual Behavior
It returns `true` instead, hence the assertion error:
```sh
$ npm test
> [email protected] test
> electron test.js
AssertionError [ERR_ASSERTION]: Expected values to be strictly equal:
true !== false
at /Users/raisinten/Desktop/temp/project/electron/test.js:10:3 {
generatedMessage: true,
code: 'ERR_ASSERTION',
actual: true,
expected: false,
operator: 'strictEqual'
}
$ echo $?
1
```
### Testcase Gist URL

|
### 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
18.1.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 20.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Offscreen rendering paint events should receive events for SELECT input elements.
### Actual Behavior
Sometimes an empty white box appears, or nothing happens.
### Testcase Gist URL
https://gist.github.com/gtalusan/c0ad56685aeb3b2c1108fbccf6b451b4
### Additional Information
Here's a screenshot when the fiddle is run with `offscreen = false`:

# safeStorage
> Allows access to simple encryption and decryption of strings for storage on the local machine.
Process: [Main](../glossary.md#main-process)
This module protects data stored on disk from being accessed by other applications or users with full disk access.
Note that on Mac, access to the system Keychain is required and
these calls can block the current thread to collect user input.
The same is true for Linux, if a password management tool is available.
## Methods
The `safeStorage` module has the following methods:
### `safeStorage.isEncryptionAvailable()`
Returns `boolean` - Whether encryption is available.
On Linux, returns true if the secret key is
available. On MacOS, returns true if Keychain is available.
On Windows, returns true once the app has emitted the `ready` event.
### `safeStorage.encryptString(plainText)`
* `plainText` string
Returns `Buffer` - An array of bytes representing the encrypted string.
This function will throw an error if encryption fails.
### `safeStorage.decryptString(encrypted)`
* `encrypted` Buffer
Returns `string` - the decrypted string. Decrypts the encrypted buffer
obtained with `safeStorage.encryptString` back into a string.
This function will throw an error if decryption fails.

[Bug]: electron.safeStorage.isEncryptionAvailable() segfaults on Linux when called before creation of the first BrowserWindow

### Electron Version
15 and 16
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 20.04
### What arch are you using?
x64
### Last Known Working Electron version
n/a
### Expected Behavior
calling `electron.safeStorage.isEncryptionAvailable()` returns a boolean
### Actual Behavior
calling `electron.safeStorage.isEncryptionAvailable()` segfaults immediately
### Testcase Gist URL
https://github.com/ganthern/safe-storage-segfault
### Additional Information
It also happens in a fresh openSUSE Leap 15.1.1 VM.
The API should be available as soon as possible (preferrably before app ready) since it's useful for apps that run on startup without immediately opening BrowserWindows.
For the record, it works as expected on MacOs and returns `false` on windows, which makes the current [documentation](https://www.electronjs.org/docs/latest/api/safe-storage#safestorageisencryptionavailable) of `isEncryptionAvailable` inaccurate.

# The config expects the following environment variables to be set:

# e.g. 'target_cpu="x86"' to build for a 32bit platform.
# https://gn.googlesource.com/gn/+/master/docs/reference.md#target_cpu
# Don't forget to set up "NPM_CONFIG_ARCH" and "TARGET_ARCH" accordningly
# if you pass a custom value for 'target_cpu'.
# - "ELECTRON_RELEASE" Set it to '1' upload binaries on success.
# - "NPM_CONFIG_ARCH" E.g. 'x86'. Is used to build native Node.js modules.
# Must match 'target_cpu' passed to "GN_EXTRA_ARGS" and "TARGET_ARCH" value.
# - "TARGET_ARCH" Choose from {'ia32', 'x64', 'arm', 'arm64', 'mips64el'}.
# Is used in some publishing scripts, but does NOT affect the Electron binary.
# Must match 'target_cpu' passed to "GN_EXTRA_ARGS" and "NPM_CONFIG_ARCH" value.
# - "UPLOAD_TO_STORAGE" Set it to '1' upload a release to the Azure bucket.
# Otherwise the release will be uploaded to the Github Releases.
# (The value is only checked if "ELECTRON_RELEASE" is defined.)

# The config expects the following environment variables to be set:

# - "GN_EXTRA_ARGS" Additional gn arguments for a build config,
# e.g. 'target_cpu="x86"' to build for a 32bit platform.
# https://gn.googlesource.com/gn/+/master/docs/reference.md#target_cpu
# Don't forget to set up "NPM_CONFIG_ARCH" and "TARGET_ARCH" accordningly
# if you pass a custom value for 'target_cpu'.
# - "ELECTRON_RELEASE" Set it to '1' upload binaries on success.
# - "NPM_CONFIG_ARCH" E.g. 'x86'. Is used to build native Node.js modules.
# Must match 'target_cpu' passed to "GN_EXTRA_ARGS" and "TARGET_ARCH" value.
# - "TARGET_ARCH" Choose from {'ia32', 'x64', 'arm', 'arm64', 'mips64el'}.
# Is used in some publishing scripts, but does NOT affect the Electron binary.
# Must match 'target_cpu' passed to "GN_EXTRA_ARGS" and "NPM_CONFIG_ARCH" value.
# - "UPLOAD_TO_STORAGE" Set it to '1' upload a release to the Azure bucket.
# Otherwise the release will be uploaded to the Github Releases.
# (The value is only checked if "ELECTRON_RELEASE" is defined.)
#
# The publishing scripts expect access tokens to be defined as env vars,

Symbol generation on 32-bit Windows release builds on nightlies and 19-x-y are failing with the following error:
```

Here's a recent nightly release build with the failure: https://ci.appveyor.com/project/electron-bot/electron-ia32-release/builds/43164264
It looks like this failure was introduced via #33454.

### Last Known Working Electron version
_No response_
### Expected Behavior
When loading an extension extension with missing files, Electron should not crash.
### Actual Behavior
When loading an extension extension with missing files Electron crashes with "Electron exited with signal SIGTRAP."
### Testcase Gist URL
https://gist.github.com/jzoss/7fd8ad289c4ebbefeb766ec4e4e2829b
### Additional Information
When loaded an extension that malformed is some way Electron crashes. I first saw this when I was unable to zip an extension and some of the files were missing. I am able to recreate it by removed all the files in a extension directory but leaving all the directories.
for example in this gist.. if you make a dir "fmkadmapgofadopljbjfkapdkoienihi" and add 3 directories "build", "icons", "popups" Electron will crash.

[Bug]: When Attempting to load extension with missing files, Electron Crashes.

### 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
18.0.3
### What operating system are you using?
macOS
### Operating System Version
macOS Monterey, Ubuntu
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When loading an extension extension with missing files, Electron should not crash.
### Actual Behavior
When loading an extension extension with missing files Electron crashes with "Electron exited with signal SIGTRAP."
### Testcase Gist URL
https://gist.github.com/jzoss/7fd8ad289c4ebbefeb766ec4e4e2829b
### Additional Information
When loaded an extension that malformed is some way Electron crashes. I first saw this when I was unable to zip an extension and some of the files were missing. I am able to recreate it by removed all the files in a extension directory but leaving all the directories.
for example in this gist.. if you make a dir "fmkadmapgofadopljbjfkapdkoienihi" and add 3 directories "build", "icons", "popups" Electron will crash.

[Bug]: When Attempting to load extension with missing files, Electron Crashes.
|
### 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
18.0.3
### What operating system are you using?
macOS
### Operating System Version
macOS Monterey, Ubuntu
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When loading an extension extension with missing files, Electron should not crash.
### Actual Behavior
When loading an extension extension with missing files Electron crashes with "Electron exited with signal SIGTRAP."
### Testcase Gist URL
https://gist.github.com/jzoss/7fd8ad289c4ebbefeb766ec4e4e2829b
### Additional Information
When loaded an extension that malformed is some way Electron crashes. I first saw this when I was unable to zip an extension and some of the files were missing. I am able to recreate it by removed all the files in a extension directory but leaving all the directories.
for example in this gist.. if you make a dir "fmkadmapgofadopljbjfkapdkoienihi" and add 3 directories "build", "icons", "popups" Electron will crash.

[Bug]: When Attempting to load extension with missing files, Electron Crashes.
|
### 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
18.0.3
### What operating system are you using?
macOS
### Operating System Version
macOS Monterey, Ubuntu
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When loading an extension extension with missing files, Electron should not crash.
### Actual Behavior
When loading an extension extension with missing files Electron crashes with "Electron exited with signal SIGTRAP."
### Testcase Gist URL
https://gist.github.com/jzoss/7fd8ad289c4ebbefeb766ec4e4e2829b
### Additional Information
When loaded an extension that malformed is some way Electron crashes. I first saw this when I was unable to zip an extension and some of the files were missing. I am able to recreate it by removed all the files in a extension directory but leaving all the directories.
for example in this gist.. if you make a dir "fmkadmapgofadopljbjfkapdkoienihi" and add 3 directories "build", "icons", "popups" Electron will crash.

[Bug]: Crash on Windows when calling `win.setTitleBarOverlay` on a window that has `titleBarStyle != 'hidden'`
|
### 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
18.2.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10 version 20H2, build 19042
### What arch are you using?
x64
### Last Known Working Electron version
18.1.0
### Expected Behavior
When `win.setTitleBarOverlay` is called, apparently the only valid option for `titleBarStyle` is `'hidden'`. So when `win` was created with `titleBarStyle` different from `'hidden'`, Electron should throw an error.
### Actual Behavior
Electron crashes unexpectedly.
### Testcase Gist URL
https://gist.github.com/wheezard/207499979a7fda8cc7d874fdb87886fc
### Additional Information
This might work on older versions, but I haven't tested it in them.

[Bug]: Crash on Windows when calling `win.setTitleBarOverlay` on a window that has `titleBarStyle != 'hidden'`
|
### 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
18.2.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10 version 20H2, build 19042
### What arch are you using?
x64
### Last Known Working Electron version
18.1.0
### Expected Behavior
When `win.setTitleBarOverlay` is called, apparently the only valid option for `titleBarStyle` is `'hidden'`. So when `win` was created with `titleBarStyle` different from `'hidden'`, Electron should throw an error.
### Actual Behavior
Electron crashes unexpectedly.
### Testcase Gist URL
https://gist.github.com/wheezard/207499979a7fda8cc7d874fdb87886fc
### Additional Information
This might work on older versions, but I haven't tested it in them.

# `<webview>` Tag
## Warning
Electron's `webview` tag is based on [Chromium's `webview`][chrome-webview], which
is undergoing dramatic architectural changes. This impacts the stability of `webviews`,
including rendering, navigation, and event routing. We currently recommend to not
use the `webview` tag and to consider alternatives, like `iframe`, [Electron's `BrowserView`](browser-view.md),
or an architecture that avoids embedded content altogether.
## Enabling
By default the `webview` tag is disabled in Electron >= 5. You need to enable the tag by
setting the `webviewTag` webPreferences option when constructing your `BrowserWindow`. For
more information see the [BrowserWindow constructor docs](browser-window.md).
## Overview
> Display external web content in an isolated frame and process.
Process: [Renderer](../glossary.md#renderer-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._
Use the `webview` tag to embed 'guest' content (such as web pages) in your
Electron app. The guest content is contained within the `webview` container.
An embedded page within your app controls how the guest content is laid out and
rendered.
Unlike an `iframe`, the `webview` runs in a separate process than your
app. It doesn't have the same permissions as your web page and all interactions
between your app and embedded content will be asynchronous. This keeps your app
safe from the embedded content. **Note:** Most methods called on the
webview from the host page require a synchronous call to the main process.
## Example
To embed a web page in your app, add the `webview` tag to your app's embedder
page (this is the app page that will display the guest content). In its simplest
form, the `webview` tag includes the `src` of the web page and css styles that
control the appearance of the `webview` container:
```html
<webview id="foo" src="https://www.github.com/" style="display:inline-flex; width:640px; height:480px"></webview>
```
If you want to control the guest content in any way, you can write JavaScript
that listens for `webview` events and responds to those events using the
`webview` methods. Here's sample code with two event listeners: one that listens
for the web page to start loading, the other for the web page to stop loading,
and displays a "loading..." message during the load time:
```html
<script>
onload = () => {
const webview = document.querySelector('webview')
const indicator = document.querySelector('.indicator')
const loadstart = () => {
indicator.innerText = 'loading...'
}
const loadstop = () => {
indicator.innerText = ''
}
webview.addEventListener('did-start-loading', loadstart)
webview.addEventListener('did-stop-loading', loadstop)
}
</script>
```
## Internal implementation
Under the hood `webview` is implemented with [Out-of-Process iframes (OOPIFs)](https://www.chromium.org/developers/design-documents/oop-iframes).
The `webview` tag is essentially a custom element using shadow DOM to wrap an
`iframe` element inside it.
So the behavior of `webview` is very similar to a cross-domain `iframe`, as
examples:
* When clicking into a `webview`, the page focus will move from the embedder
frame to `webview`.
* You can not add keyboard, mouse, and scroll event listeners to `webview`.
* All reactions between the embedder frame and `webview` are asynchronous.
## CSS Styling Notes
Please note that the `webview` tag's style uses `display:flex;` internally to
ensure the child `iframe` element fills the full height and width of its `webview`
container when used with traditional and flexbox layouts. Please do not
overwrite the default `display:flex;` CSS property, unless specifying
`display:inline-flex;` for inline layout.
## Tag Attributes
The `webview` tag has the following attributes:
### `src`
```html
<webview src="https://www.github.com/"></webview>
```
A `string` representing the visible URL. Writing to this attribute initiates top-level
navigation.
Assigning `src` its own value will reload the current page.
The `src` attribute can also accept data URLs, such as
`data:text/plain,Hello, world!`.
### `nodeintegration`
```html
<webview src="http://www.google.com/" nodeintegration></webview>
```
A `boolean`. When this attribute is present the guest page in `webview` will have node
integration and can use node APIs like `require` and `process` to access low
level system resources. Node integration is disabled by default in the guest
page.
### `nodeintegrationinsubframes`
```html
<webview src="http://www.google.com/" nodeintegrationinsubframes></webview>
```
A `boolean` for the experimental option for enabling NodeJS support in sub-frames such as iframes
inside the `webview`. All your preloads will load for every iframe, you can
use `process.isMainFrame` to determine if you are in the main frame or not.
This option is disabled by default in the guest page.
### `plugins`
```html
<webview src="https://www.github.com/" plugins></webview>
```
A `boolean`. When this attribute is present the guest page in `webview` will be able to use
browser plugins. Plugins are disabled by default.
### `preload`
```html
<!-- from a file -->
<webview src="https://www.github.com/" preload="./test.js"></webview>
<!-- or if you want to load from an asar archive -->
<webview src="https://www.github.com/" preload="./app.asar/test.js"></webview>
```
A `string` that specifies a script that will be loaded before other scripts run in the guest
page. The protocol of script's URL must be `file:` (even when using `asar:` archives) because
it will be loaded by Node's `require` under the hood, which treats `asar:` archives as virtual
directories.
When the guest page doesn't have node integration this script will still have
access to all Node APIs, but global objects injected by Node will be deleted
after this script has finished executing.
### `httpreferrer`
```html
<webview src="https://www.github.com/" httpreferrer="http://cheng.guru"></webview>
```
A `string` that sets the referrer URL for the guest page.
### `useragent`
```html
<webview src="https://www.github.com/" useragent="Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; AS; rv:11.0) like Gecko"></webview>
```
A `string` that sets the user agent for the guest page before the page is navigated to. Once the
page is loaded, use the `setUserAgent` method to change the user agent.
### `disablewebsecurity`
```html
<webview src="https://www.github.com/" disablewebsecurity></webview>
```
A `boolean`. When this attribute is present the guest page will have web security disabled.
Web security is enabled by default.
### `partition`
```html
<webview src="https://github.com" partition="persist:github"></webview>
<webview src="https://electronjs.org" partition="electron"></webview>
```
A `string` that sets the session used by the page. If `partition` starts with `persist:`, the
page will use a persistent session available to all pages in the app with the
same `partition`. if there is no `persist:` prefix, the page will use an
in-memory session. By assigning the same `partition`, multiple pages can share
the same session. If the `partition` is unset then default session of the app
will be used.
This value can only be modified before the first navigation, since the session
of an active renderer process cannot change. Subsequent attempts to modify the
value will fail with a DOM exception.
### `allowpopups`
```html
<webview src="https://www.github.com/" allowpopups></webview>
```
A `boolean`. When this attribute is present the guest page will be allowed to open new
windows. Popups are disabled by default.
### `webpreferences`
```html
<webview src="https://github.com" webpreferences="allowRunningInsecureContent, javascript=no"></webview>
```
A `string` which is a comma separated list of strings which specifies the web preferences to be set on the webview.
The full list of supported preference strings can be found in [BrowserWindow](browser-window.md#new-browserwindowoptions).
The string follows the same format as the features string in `window.open`.
A name by itself is given a `true` boolean value.
A preference can be set to another value by including an `=`, followed by the value.
Special values `yes` and `1` are interpreted as `true`, while `no` and `0` are interpreted as `false`.
### `enableblinkfeatures`
```html
<webview src="https://www.github.com/" enableblinkfeatures="PreciseMemoryInfo, CSSVariables"></webview>
```
A `string` which is a list of strings which specifies the blink features to be enabled separated by `,`.
The full list of supported feature strings can be found in the
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
### `disableblinkfeatures`
```html
<webview src="https://www.github.com/" disableblinkfeatures="PreciseMemoryInfo, CSSVariables"></webview>
```
A `string` which is a list of strings which specifies the blink features to be disabled separated by `,`.
The full list of supported feature strings can be found in the
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
## Methods
The `webview` tag has the following methods:
**Note:** The webview element must be loaded before using the methods.

* `frameId` [number, number] - `[processId, frameId]`
* `channel` string
* `...args` any[]
Returns `Promise<void>`
Send an asynchronous message to renderer process via `channel`, you can also
send arbitrary arguments. The renderer process can handle the message by
listening to the `channel` event with the [`ipcRenderer`](ipc-renderer.md) module.
See [webContents.sendToFrame](web-contents.md#contentssendtoframeframeid-channel-args) for
examples.
### `<webview>.sendInputEvent(event)`
* `event` [MouseInputEvent](structures/mouse-input-event.md) | [MouseWheelInputEvent](structures/mouse-wheel-input-event.md) | [KeyboardInputEvent](structures/keyboard-input-event.md)
Returns `Promise<void>`
Sends an input `event` to the page.
See [webContents.sendInputEvent](web-contents.md#contentssendinputeventinputevent)
for detailed description of `event` object.
### `<webview>.setZoomFactor(factor)`
* `factor` number - Zoom factor.
Changes the zoom factor to the specified factor. Zoom factor is
zoom percent divided by 100, so 300% = 3.0.
### `<webview>.setZoomLevel(level)`
* `level` number - Zoom level.
Changes the zoom level to the specified level. The original size is 0 and each
increment above or below represents zooming 20% larger or smaller to default
limits of 300% and 50% of original size, respectively. 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.
### `<webview>.getZoomFactor()`
Returns `number` - the current zoom factor.
### `<webview>.getZoomLevel()`
Returns `number` - the current zoom level.
### `<webview>.setVisualZoomLevelLimits(minimumLevel, maximumLevel)`
* `minimumLevel` number
* `maximumLevel` number
Returns `Promise<void>`
Sets the maximum and minimum pinch-to-zoom level.
### `<webview>.showDefinitionForSelection()` _macOS_
Shows pop-up dictionary that searches the selected word on the page.
### `<webview>.getWebContentsId()`
Returns `number` - The WebContents ID of this `webview`.
## DOM Events
The following DOM events are available to the `webview` tag:
### Event: 'load-commit'
Returns:

* `message` string - The actual console message
* `line` Integer - The line number of the source that triggered this console message
* `sourceId` string
Fired when the guest window logs a console message.
The following example code forwards all log messages to the embedder's console
without regard for log level or other properties.
```javascript
const webview = document.querySelector('webview')
webview.addEventListener('console-message', (e) => {
console.log('Guest page logged a message:', e.message)
})
```
### Event: 'found-in-page'

[`webview.findInPage`](#webviewfindinpagetext-options) request.
```javascript
const webview = document.querySelector('webview')
webview.addEventListener('found-in-page', (e) => {
webview.stopFindInPage('keepSelection')
})
const requestId = webview.findInPage('test')
console.log(requestId)
```
### Event: 'new-window'
Returns:
* `url` string

`new-window`, `save-to-disk` and `other`.
* `options` BrowserWindowConstructorOptions - The options which should be used for creating the new
[`BrowserWindow`](browser-window.md).
Fired when the guest page attempts to open a new browser window.
The following example code opens the new url in system's default browser.
```javascript
const { shell } = require('electron')
const webview = document.querySelector('webview')
webview.addEventListener('new-window', async (e) => {
const protocol = (new URL(e.url)).protocol
if (protocol === 'http:' || protocol === 'https:') {
await shell.openExternal(e.url)
}
})
```
### Event: 'will-navigate'
Returns:
* `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 `<webview>.loadURL` and `<webview>.back`.
It is also not emitted during in-page navigation, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` does __NOT__ have any effect.

Emitted after a server side redirect occurs during navigation. For example a 302
redirect.
### Event: 'did-navigate'
Returns:
* `url` string
Emitted when a 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:
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations,
* `isMainFrame` boolean

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:
* `isMainFrame` boolean
* `url` string
Emitted when an in-page navigation happened.
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: 'close'
Fired when the guest page attempts to close itself.
The following example code navigates the `webview` to `about:blank` when the
guest attempts to close itself.
```javascript

between guest page and embedder page:
```javascript
// In embedder page.
const webview = document.querySelector('webview')
webview.addEventListener('ipc-message', (event) => {
console.log(event.channel)
// Prints "pong"
})
webview.send('ping')
```
```javascript
// In guest page.
const { ipcRenderer } = require('electron')

# `<webview>` Tag
## Warning
Electron's `webview` tag is based on [Chromium's `webview`][chrome-webview], which
is undergoing dramatic architectural changes. This impacts the stability of `webviews`,
including rendering, navigation, and event routing. We currently recommend to not
use the `webview` tag and to consider alternatives, like `iframe`, [Electron's `BrowserView`](browser-view.md),
or an architecture that avoids embedded content altogether.
## Enabling
By default the `webview` tag is disabled in Electron >= 5. You need to enable the tag by
setting the `webviewTag` webPreferences option when constructing your `BrowserWindow`. For
more information see the [BrowserWindow constructor docs](browser-window.md).
## Overview
> Display external web content in an isolated frame and process.
Process: [Renderer](../glossary.md#renderer-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._
Use the `webview` tag to embed 'guest' content (such as web pages) in your
Electron app. The guest content is contained within the `webview` container.
An embedded page within your app controls how the guest content is laid out and
rendered.
Unlike an `iframe`, the `webview` runs in a separate process than your
app. It doesn't have the same permissions as your web page and all interactions
between your app and embedded content will be asynchronous. This keeps your app
safe from the embedded content. **Note:** Most methods called on the
webview from the host page require a synchronous call to the main process.
## Example
To embed a web page in your app, add the `webview` tag to your app's embedder
page (this is the app page that will display the guest content). In its simplest
form, the `webview` tag includes the `src` of the web page and css styles that
control the appearance of the `webview` container:
```html
<webview id="foo" src="https://www.github.com/" style="display:inline-flex; width:640px; height:480px"></webview>
```
If you want to control the guest content in any way, you can write JavaScript
that listens for `webview` events and responds to those events using the
`webview` methods. Here's sample code with two event listeners: one that listens
for the web page to start loading, the other for the web page to stop loading,
and displays a "loading..." message during the load time:
```html
<script>
onload = () => {
const webview = document.querySelector('webview')
const indicator = document.querySelector('.indicator')
const loadstart = () => {
indicator.innerText = 'loading...'
}
const loadstop = () => {
indicator.innerText = ''
}
webview.addEventListener('did-start-loading', loadstart)
webview.addEventListener('did-stop-loading', loadstop)
}
</script>
```
## Internal implementation
Under the hood `webview` is implemented with [Out-of-Process iframes (OOPIFs)](https://www.chromium.org/developers/design-documents/oop-iframes).
The `webview` tag is essentially a custom element using shadow DOM to wrap an
`iframe` element inside it.
So the behavior of `webview` is very similar to a cross-domain `iframe`, as
examples:
* When clicking into a `webview`, the page focus will move from the embedder
frame to `webview`.
* You can not add keyboard, mouse, and scroll event listeners to `webview`.
* All reactions between the embedder frame and `webview` are asynchronous.
## CSS Styling Notes
Please note that the `webview` tag's style uses `display:flex;` internally to
ensure the child `iframe` element fills the full height and width of its `webview`
container when used with traditional and flexbox layouts. Please do not
overwrite the default `display:flex;` CSS property, unless specifying
`display:inline-flex;` for inline layout.
## Tag Attributes
The `webview` tag has the following attributes:
### `src`
```html
<webview src="https://www.github.com/"></webview>
```
A `string` representing the visible URL. Writing to this attribute initiates top-level
navigation.
Assigning `src` its own value will reload the current page.
The `src` attribute can also accept data URLs, such as
`data:text/plain,Hello, world!`.
### `nodeintegration`
```html
<webview src="http://www.google.com/" nodeintegration></webview>
```
A `boolean`. When this attribute is present the guest page in `webview` will have node
integration and can use node APIs like `require` and `process` to access low
level system resources. Node integration is disabled by default in the guest
page.
### `nodeintegrationinsubframes`
```html
<webview src="http://www.google.com/" nodeintegrationinsubframes></webview>
```
A `boolean` for the experimental option for enabling NodeJS support in sub-frames such as iframes
inside the `webview`. All your preloads will load for every iframe, you can
use `process.isMainFrame` to determine if you are in the main frame or not.
This option is disabled by default in the guest page.
### `plugins`
```html
<webview src="https://www.github.com/" plugins></webview>
```
A `boolean`. When this attribute is present the guest page in `webview` will be able to use
browser plugins. Plugins are disabled by default.
### `preload`
```html
<!-- from a file -->
<webview src="https://www.github.com/" preload="./test.js"></webview>
<!-- or if you want to load from an asar archive -->
<webview src="https://www.github.com/" preload="./app.asar/test.js"></webview>
```
A `string` that specifies a script that will be loaded before other scripts run in the guest
page. The protocol of script's URL must be `file:` (even when using `asar:` archives) because
it will be loaded by Node's `require` under the hood, which treats `asar:` archives as virtual
directories.
When the guest page doesn't have node integration this script will still have
access to all Node APIs, but global objects injected by Node will be deleted
after this script has finished executing.
### `httpreferrer`
```html
<webview src="https://www.github.com/" httpreferrer="http://cheng.guru"></webview>
```
A `string` that sets the referrer URL for the guest page.
### `useragent`
```html
<webview src="https://www.github.com/" useragent="Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; AS; rv:11.0) like Gecko"></webview>
```
A `string` that sets the user agent for the guest page before the page is navigated to. Once the
page is loaded, use the `setUserAgent` method to change the user agent.
### `disablewebsecurity`
```html
<webview src="https://www.github.com/" disablewebsecurity></webview>
```
A `boolean`. When this attribute is present the guest page will have web security disabled.
Web security is enabled by default.
### `partition`
```html
<webview src="https://github.com" partition="persist:github"></webview>
<webview src="https://electronjs.org" partition="electron"></webview>
```
A `string` that sets the session used by the page. If `partition` starts with `persist:`, the
page will use a persistent session available to all pages in the app with the
same `partition`. if there is no `persist:` prefix, the page will use an
in-memory session. By assigning the same `partition`, multiple pages can share
the same session. If the `partition` is unset then default session of the app
will be used.
This value can only be modified before the first navigation, since the session
of an active renderer process cannot change. Subsequent attempts to modify the
value will fail with a DOM exception.
### `allowpopups`
```html
<webview src="https://www.github.com/" allowpopups></webview>
```
A `boolean`. When this attribute is present the guest page will be allowed to open new
windows. Popups are disabled by default.
### `webpreferences`
```html
<webview src="https://github.com" webpreferences="allowRunningInsecureContent, javascript=no"></webview>
```
A `string` which is a comma separated list of strings which specifies the web preferences to be set on the webview.
The full list of supported preference strings can be found in [BrowserWindow](browser-window.md#new-browserwindowoptions).
The string follows the same format as the features string in `window.open`.
A name by itself is given a `true` boolean value.
A preference can be set to another value by including an `=`, followed by the value.
Special values `yes` and `1` are interpreted as `true`, while `no` and `0` are interpreted as `false`.
### `enableblinkfeatures`
```html
<webview src="https://www.github.com/" enableblinkfeatures="PreciseMemoryInfo, CSSVariables"></webview>
```
A `string` which is a list of strings which specifies the blink features to be enabled separated by `,`.
The full list of supported feature strings can be found in the
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
### `disableblinkfeatures`
```html
<webview src="https://www.github.com/" disableblinkfeatures="PreciseMemoryInfo, CSSVariables"></webview>
```
A `string` which is a list of strings which specifies the blink features to be disabled separated by `,`.
The full list of supported feature strings can be found in the
[RuntimeEnabledFeatures.json5][runtime-enabled-features] file.
## Methods
The `webview` tag has the following methods:
**Note:** The webview element must be loaded before using the methods.

[Bug]: setSize on BrowserWindow during will-resize is applied on mouse-up and not immediately
|
### 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
17.4.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro 21H2
### What arch are you using?
ia32
### Last Known Working Electron version
17.3.1
### Expected Behavior
When calling the setSize on a browser window in the main process during the will-resize event, the width and height should be applied immediately in combination with the preventDefault on the event.
### Actual Behavior
When calling the setSize on a browser window in the main process during the will-resize event, the width and height isn't set immediately anymore in combination with the preventDefault on the event. When you resize the window and during will-resize event you set the size of the window (for e.g. handling minimal width and minimal height), the new size isn't affective immediately. The size is applied when you stop resizing by a mouse up. With Electron version 17.3.1 and lower the setSize worked fine during will-resize event.
### Testcase Gist URL
https://gist.github.com/ccc3e3fa4f724b5d717d9fc8f9c8dfe2
### Additional Information
I suspect that the new behavior is caused by the following PR:
https://github.com/electron/electron/pull/33288
My application has some behavior implemented for controlling the minimal width and height in combination with the zoom factor. This is now broken and resizing freezes the resizing when the minimal width or height is reached. The setSize I use to continue resizing for the width/height where the limit isn't reached yet. It looks like the new behavior in Electron 17.4.0 is delaying the setSize until resize is done which breaks the behavior of my application.

[Bug]: setSize on BrowserWindow during will-resize is applied on mouse-up and not immediately
|
### 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
17.4.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro 21H2
### What arch are you using?
ia32
### Last Known Working Electron version
17.3.1
### Expected Behavior
When calling the setSize on a browser window in the main process during the will-resize event, the width and height should be applied immediately in combination with the preventDefault on the event.
### Actual Behavior
When calling the setSize on a browser window in the main process during the will-resize event, the width and height isn't set immediately anymore in combination with the preventDefault on the event. When you resize the window and during will-resize event you set the size of the window (for e.g. handling minimal width and minimal height), the new size isn't affective immediately. The size is applied when you stop resizing by a mouse up. With Electron version 17.3.1 and lower the setSize worked fine during will-resize event.
### Testcase Gist URL
https://gist.github.com/ccc3e3fa4f724b5d717d9fc8f9c8dfe2
### Additional Information
I suspect that the new behavior is caused by the following PR:
https://github.com/electron/electron/pull/33288
My application has some behavior implemented for controlling the minimal width and height in combination with the zoom factor. This is now broken and resizing freezes the resizing when the minimal width or height is reached. The setSize I use to continue resizing for the width/height where the limit isn't reached yet. It looks like the new behavior in Electron 17.4.0 is delaying the setSize until resize is done which breaks the behavior of my application.
