Breaking Changes

Breaking-Änderungen werden hier dokumentiert, und Veraltungswarnungen werden js-Code nach Möglichkeit hinzugefügt, mindestens eine Hauptversion, bevor die Änderung vorgenommen wird.

Typen von Breaking-Änderungen

In diesem Dokument wird die folgende Konvention zur Kategorisierung von Breaking-Änderungen verwendet:

API geändert: Die API wurde so geändert, dass Code, der nicht aktualisiert wurde, garantiert eine Ausnahme wirft.
Verhalten geändert: Das Verhalten von Electron hat sich geändert, aber nicht so, dass eine Ausnahme unbedingt geworfen wird.
Standard geändert: Code, der vom alten Standardwert abhängig ist, funktioniert möglicherweise nicht mehr und wirft nicht notwendigerweise eine Ausnahme. Das alte Verhalten kann durch explizite Angabe des Wertes wiederhergestellt werden.
Veraltet: Eine API wurde als veraltet markiert. Die API wird weiterhin funktionieren, sendet aber eine Veraltungswarnung aus und wird in einer zukünftigen Version entfernt.
Entfernt: Eine API oder Funktion wurde entfernt und wird von Electron nicht mehr unterstützt.

Geplante Bruch-API-Änderungen (33.0)

Behavior Changed: `webContents` property on `login` on `app`

The webContents property in the login event from app will be null when the event is triggered for requests from the utility process created with respondToAuthRequestsFromMainProcess option.

Veraltet: `systemPreferences.accessibilityDisplayShouldReduceTransparency`

The systemPreferences.accessibilityDisplayShouldReduceTransparency property is now deprecated in favor of the new nativeTheme.prefersReducedTransparency, which provides identical information and works cross-platform.

// Deprecated
const shouldReduceTransparency = systemPreferences.accessibilityDisplayShouldReduceTransparency

// Replace with:
const prefersReducedTransparency = nativeTheme.prefersReducedTransparency

Removed: `File.path`

The nonstandard path property of the Web File object was added in an early version of Electron as a convenience method for working with native files when doing everything in the renderer was more common. However, it represents a deviation from the standard and poses a minor security risk as well, so beginning in Electron 32.0 it has been removed in favor of the webUtils.getPathForFile method.

// Before (renderer)

const file = document.querySelector('input[type=file]')
alert(`Uploaded file path was: ${file.path}`)

// After (renderer)

const file = document.querySelector('input[type=file]')
electron.showFilePath(file)

// (preload)
const { contextBridge, webUtils } = require('electron')

contextBridge.exposeInMainWorld('electron', {
  showFilePath (file) {
    // It's best not to expose the full file path to the web content if
    // possible.
    const path = webUtils.getPathForFile(file)
    alert(`Uploaded file path was: ${path}`)
  }
})

Deprecated: `clearHistory`, `canGoBack`, `goBack`, `canGoForward`, `goForward`, `goToIndex`, `canGoToOffset`, `goToOffset` on `WebContents`

The navigation-related APIs are now deprecated.

These APIs have been moved to the navigationHistory property of WebContents to provide a more structured and intuitive interface for managing navigation history.

// Deprecated
win.webContents.clearHistory()
win.webContents.canGoBack()
win.webContents.goBack()
win.webContents.canGoForward()
win.webContents.goForward()
win.webContents.goToIndex(index)
win.webContents.canGoToOffset()
win.webContents.goToOffset(index)

// Replace with
win.webContents.navigationHistory.clear()
win.webContents.navigationHistory.canGoBack()
win.webContents.navigationHistory.goBack()
win.webContents.navigationHistory.canGoForward()
win.webContents.navigationHistory.goForward()
win.webContents.navigationHistory.canGoToOffset()
win.webContents.navigationHistory.goToOffset(index)

Removed: `WebSQL` support

Chromium has removed support for WebSQL upstream, transitioning it to Android only. See Chromium's intent to remove discussion for more information.

Behavior Changed: `nativeImage.toDataURL` will preserve PNG colorspace

PNG decoder implementation has been changed to preserve colorspace data, the encoded data returned from this function now matches it.

See crbug.com/332584706 for more information.

Behavior Changed: `window.flashFrame(bool)` will flash dock icon continuously on macOS

This brings the behavior to parity with Windows and Linux. Prior behavior: The first flashFrame(true) bounces the dock icon only once (using the NSInformationalRequest level) and flashFrame(false) does nothing. New behavior: Flash continuously until flashFrame(false) is called. This uses the NSCriticalRequest level instead. To explicitly use NSInformationalRequest to cause a single dock icon bounce, it is still possible to use dock.bounce('informational').

Geplante Bruch-API-Änderungen (30.0)

Behavior Changed: cross-origin iframes now use Permission Policy to access features

Cross-origin iframes must now specify features available to a given iframe via the allow attribute in order to access them.

See documentation for more information.

Removed: The `--disable-color-correct-rendering` switch

This switch was never formally documented but it's removal is being noted here regardless. Chromium itself now has better support for color spaces so this flag should not be needed.

Behavior Changed: `BrowserView.setAutoResize` behavior on macOS

In Electron 30, BrowserView is now a wrapper around the new WebContentsView API.

Previously, the setAutoResize function of the BrowserView API was backed by autoresizing on macOS, and by a custom algorithm on Windows and Linux. For simple use cases such as making a BrowserView fill the entire window, the behavior of these two approaches was identical. However, in more advanced cases, BrowserViews would be autoresized differently on macOS than they would be on other platforms, as the custom resizing algorithm for Windows and Linux did not perfectly match the behavior of macOS's autoresizing API. The autoresizing behavior is now standardized across all platforms.

If your app uses BrowserView.setAutoResize to do anything more complex than making a BrowserView fill the entire window, it's likely you already had custom logic in place to handle this difference in behavior on macOS. If so, that logic will no longer be needed in Electron 30 as autoresizing behavior is consistent.

Deprecated: `BrowserView`

The BrowserView class has been deprecated and replaced by the new WebContentsView class.

BrowserView related methods in BrowserWindow have also been deprecated:

BrowserWindow.fromBrowserView(browserView)
win.setBrowserView(browserView)
win.getBrowserView()
win.addBrowserView(browserView)
win.removeBrowserView(browserView)
win.setTopBrowserView(browserView)
win.getBrowserViews()

Removed: `params.inputFormType` property on `context-menu` on `WebContents`

The inputFormType property of the params object in the context-menu event from WebContents has been removed. Use the new formControlType property instead.

Entfernt: `process.getIOCounters()`

Chromium has removed access to this information.

Behavior Changed: `ipcRenderer` can no longer be sent over the `contextBridge`

Attempting to send the entire ipcRenderer module as an object over the contextBridge will now result in an empty object on the receiving side of the bridge. This change was made to remove / mitigate a security footgun. You should not directly expose ipcRenderer or its methods over the bridge. Instead, provide a safe wrapper like below:

contextBridge.exposeInMainWorld('app', {
  onEvent: (cb) => ipcRenderer.on('foo', (e, ...args) => cb(args))
})

Removed: `renderer-process-crashed` event on `app`

The renderer-process-crashed event on app has been removed. Use the new render-process-gone event instead.

Veraltet: `BrowserWindow.setTrafficLightPosition(position)`

BrowserWindow.setTrafficLightPosition(position) wurde veraltet, die BrowserWindow.setWindowButtonPosition(position) API sollte stattdessen verwendet werden, die null anstelle von { x: 0, y: 0 } akzeptiert, um die Position auf Systemstandart zurückzusetzen.

// Veraltet in Electron 25

  // Keine benutzerdefinierte Position.
}

Geplante Bruch-API-Änderungen (24.0)

API geändert: `nativeImage.createThumbnailFromPath(path, size)`

The maxSize parameter has been changed to size to reflect that the size passed in will be the size the thumbnail created. Previously, Windows would not scale the image up if it were smaller than maxSize, and macOS would always set the size to maxSize. Behavior is now the same across platforms.

Aktualisiertes Verhalten:

// a 128x128 image.
const imagePath = path.join('path', 'to', 'capybara.png')

// Scaling up a smaller image.
const upSize = { width: 256, height: 256 }
nativeImage.createThumbnailFromPath(imagePath, upSize).then(result => {
  console.log(result.getSize()) // { width: 256, height: 256 }
})

// Scaling down a larger image.
const downSize = { width: 64, height: 64 }
nativeImage.createThumbnailFromPath(imagePath, downSize).then(result => {
  console.log(result.getSize()) // { width: 64, height: 64 }
})

Vorheriges Verhalten (unter Windows):

// a 128x128 image
const imagePath = path.join('path', 'to', 'capybara.png')
const size = { width: 256, height: 256 }
nativeImage.createThumbnailFromPath(imagePath, size).then(result => {
  console.log(result.getSize()) // { width: 128, height: 128 }
})

Geplante Bruch-API-Änderungen (23.0)

Behavior Changed: Draggable Regions on macOS

The implementation of draggable regions (using the CSS property -webkit-app-region: drag) has changed on macOS to bring it in line with Windows and Linux. Previously, when a region with -webkit-app-region: no-drag overlapped a region with -webkit-app-region: drag, the no-drag region would always take precedence on macOS, regardless of CSS layering. That is, if a drag region was above a no-drag region, it would be ignored. Beginning in Electron 23, a drag region on top of a no-drag region will correctly cause the region to be draggable.

Additionally, the customButtonsOnHover BrowserWindow property previously created a draggable region which ignored the -webkit-app-region CSS property. This has now been fixed (see #37210 for discussion).

As a result, if your app uses a frameless window with draggable regions on macOS, the regions which are draggable in your app may change in Electron 23.

Removed: Windows 7 / 8 / 8.1 support

Windows 7, Windows 8, and Windows 8.1 are no longer supported. Electron follows the planned Chromium deprecation policy, which will deprecate Windows 7 support beginning in Chromium 109.

Older versions of Electron will continue to run on these operating systems, but Windows 10 or later will be required to run Electron v23.0.0 and higher.

Removed: BrowserWindow `scroll-touch-*` events

The deprecated scroll-touch-begin, scroll-touch-end and scroll-touch-edge events on BrowserWindow have been removed. Instead, use the newly available input-event event on WebContents.

// Removed in Electron 23.0
win.on('scroll-touch-begin', scrollTouchBegin)
win.on('scroll-touch-edge', scrollTouchEdge)
win.on('scroll-touch-end', scrollTouchEnd)

// Replace with
win.webContents.on('input-event', (_, event) => {
  if (event.type === 'gestureScrollBegin') {
    scrollTouchBegin()
  } else if (event.type === 'gestureScrollUpdate') {
    scrollTouchEdge()
  } else if (event.type === 'gestureScrollEnd') {
    scrollTouchEnd()
  }
})

Entfernt: `webContents.incrementCapturerCount(stayHidden, stayAwake)`

The webContents.incrementCapturerCount(stayHidden, stayAwake) function has been removed. Es wird nun automatisch von webContents.capturePage bearbeitet, wenn eine Seitenerfassung abgeschlossen ist.

Removed: macOS 10.11 / 10.12 support

macOS 10.11 (El Capitan) and macOS 10.12 (Sierra) are no longer supported by Chromium.

Older versions of Electron will continue to run on these operating systems, but macOS 10.13 (High Sierra) or later will be required to run Electron v20.0.0 and higher.

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.

Entfernt: `skipTaskbar` unter 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.

API geändert: `session.setDevicePermissionHandler(handler)`

The handler invoked when session.setDevicePermissionHandler(handler) is used has a change to its arguments. This handler no longer is passed a frame WebFrameMain, but instead is passed the origin, which is the origin that is checking for device permission.

Entfernt: `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. Seit Electron 15 ist nativeWindowOpen standardmäßig aktiviert.

See the documentation for window.open in Electron for more details.

Entfernt: `desktopCapturer.getSources` im Renderer

Die API desktopCapturer.getSources ist jetzt nur im Hauptprozess verfügbar. Dies wurde geändert, um die Standardsicherheit von Electron Apps zu verbessern.

Wenn Sie diese Funktion benötigen, kann sie wie folgt ersetzt werden:

// Main process
const { ipcMain, desktopCapturer } = require('electron')

ipcMain.handle(
  'DESKTOP_CAPTURER_GET_SOURCES',
  (event, opts) => desktopCapturer.getSources(opts)
)

// 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`

See the documentation for window.open in Electron for more details.

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 for details on how to replace this API in your app.

Standardwert geändert: `nativeWindowOpen` ist standardmäßig auf `true` eingestellt

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 for more details.

Veraltet: `app.runningUnderRosettaTranslation`

The app.runningUnderRosettaTranslation property has been deprecated. App.runningUnderARM64Translation

// Veraltet
console.log(app.runningUnderRosettaTranslation)
// Ersetzen durch
console.log(app.runningUnderARM64Translation)

Entfernt: `remote` Modul

The remote module was deprecated in Electron 12, and will be removed in Electron 14. It is replaced by the @electron/remote module.

// Veraltet in Electron 12:
const { BrowserWindow } = require('electron').remote

// Ersetzen von:
sonst { BrowserWindow } = require('@electron/remote')

// Im Hauptprozess:
require('@electron/remote/main').initialize()

Entfernt: `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.

Weitere Informationen findest du unter #18397.

Entfernt: Browserfenster-Affinität

Die Einstellung Affinität beim Erstellen eines neuen BrowserWindow wird entfernt als Teil unseres Plans, sich stärker an das Prozessmodell von Chromium für Sicherheit, Leistung und Wartbarkeit anzupassen.

Weitere Informationen findest du unter #18397.

API geändert: `window.open()`

Der optionale Parameter FrameName legt nicht mehr den Titel des Fensters fest. Dies folgt nun der Spezifikation, die in der nativen Dokumentation unter dem zugehörigen Parameter windowName beschrieben wird.

If you were using this parameter to set the title of a window, you can instead use win.setTitle(title).

Entfernt: `worldSafeExecuteJavaScript`

In Electron 14 wird worldSafeExecuteJavaScript entfernt. Es gibt keine Alternative, bitte stelle sicher, dass dein Code mit dieser Eigenschaft funktioniert. Es wurde standardmäßig aktiviert, da Electron 12.

Sie werden von dieser Änderung betroffen sein, wenn Sie entweder webFrame.executeJavaScript oder webFrame.executeJavaScriptInIsolatedWorld verwenden. You will need to ensure that values returned by either of those methods are supported by the Context Bridge API as these methods use the same value passing semantics.

Entfernt: BrowserWindowConstructorOptions, die von übergeordneten Fenstern geerbt werden

Vor Electron 14 würden Fenster, die mit window.open geöffnet wurden, BrowserWindow Konstruktor Optionen wie transparent und resizable von ihrem Elternfenster erben. Beginning with Electron 14, this behavior is removed, and windows will not inherit any BrowserWindow constructor options from their parents.

Stattdessen explizit Optionen für das neue Fenster mit setWindowOpenHandler setzen:

webContents.setWindowOpenHandler((details) => {
  return {
    action: 'allow',
    overrideBrowserWindowOptions: {
      // ...
    }
  }
})

Entfernt: `additionalFeatures`

Die veraltete additionalFeatures Eigenschaft in den new-window und did-create-window Events von WebContent wurde entfernt. Da new-window Positionsargumente verwendet, ist das Argument immer noch vorhanden, wird aber immer das leere Array [] sein. (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.

// Entfernt in Electron 14
// Ausgelöst von 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']) {
    // ...
  }
})

API geändert: `session.setPermissionCheckHandler(handler)`

Die Handler Methoden ersten Parameters waren zuvor immer ein webContents, es kann jetzt manchmal null sein. Sie sollten die requestingOrigin, einbettenOrigin und securityOrigin Eigenschaften verwenden, um auf die Berechtigungsprüfung korrekt zu reagieren. Da der Webcontent null sein kann nicht mehr auf ihn angewiesen werden.

// Alter Code
session.setPermissionCheckHandler((webContents, permission) => {
  if (webContents.getURL().startsWith('https://google.com/') && permission === 'notification') {
    return true
  }
  return false
})

// Ersetzen mit
session.setPermissionCheckHandler((webContents, permission, requestingOrigin) => {
  if (new URL(requestingOrigin).hostname === 'google.com' && permission === 'notification') {
    return true
  }
  return false
})

Removed: `shell.moveItemToTrash()`

Die veraltete synchrone shell.moveItemToTrash() API wurde entfernt. Verwende stattdessen die asynchrone shell.trashItem().

// Entfernt in Electron 13
shell.moveItemTosh(path)
// Ersetzen durch
shell.trashItem(path).then(/* ... */)

Entfernt: `BrowserWindow` Erweiterungs-APIs

Die veralteten Erweiterungs-APIs wurden entfernt:

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()

// In Electron 13 entfernt
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Ersetzen durch
session.defaultSession.loadExtension(path)

// In Electron 13 entfernt
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Ersetzen durch
session.defaultSession.loadExtension(path)

// In Electron 13 entfernt
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Ersetzen durch
session.defaultSession.getAllExtensions()

Eliminado: métodos en `systemPreferences`

Die folgenden systemPreferences Methoden wurden veraltet:

systemPreferences.isDarkMode()
systemPreferences.isInvertedColorScheme()
systemPreferences.isHighContrastColorScheme()

Verwende stattdessen die folgenden nativeTheme Eigenschaften:

nativeTheme.shouldUseDarkColors
nativeTheme.shouldUseInvertedColorScheme
nativeTheme.shouldUseHighContrastColors

// Entfernt in Electron 13
systemPreferences.isDarkMode()
// Ersetzen durch
nativeTheme.shouldUseDarkColors

// Entfernt in Electron 13
systemPreferences. sInvertedColorScheme()
// Ersetzen durch
nativeTheme.shouldUseInvertedColorScheme

// In Electron 13 entfernt
systemPreferences.isHighContrastColorScheme()
// Ersetzen durch
nativeTheme.shouldUseHighContrastColorColorScheme

Veraltet: WebContents `new-window` Ereignis

Das new-window Ereignis von WebContents wurde veraltet. Es wird durch webContents.setWindowOpenHandler() ersetzt.

// Veraltet in Electron 13
webContents.on('new-window', (event) => {
  event. reventDefault()
})

// Ersetzen durch
webContents.setWindowOpenHandler((details) => {
  return { action: 'deny' }
})

Entfernt: Pepper Flash Unterstützung

Chromium hat die Unterstützung für Flash entfernt, und deshalb müssen wir diesem Beispiel folgen. Weitere Details findest du in der Flash-Roadmap von Chromium.

Standardwert geändert: `worldSafeExecuteJavaScript` ist standardmäßig auf `true` eingestellt

In Electron 12, worldSafeExecuteJavaScript wird standardmäßig aktiviert. Um das vorherige Verhalten wiederherzustellen, muss worldSafeExecuteJavaScript: false in WebPreferences angegeben werden. Bitte beachte, dass die Einstellung dieser Option auf false unsicher ist.

Diese Einstellung wird in Electron 14 entfernt, also migriere bitte deinen Code um den Standardwert zu unterstützen.

Default Changed: `contextIsolation` defaults to `true`

In Electron 12, contextIsolation wird standardmäßig aktiviert. Um das vorherige Verhalten wiederherzustellen, muss contextIsolation: false in WebPreferences angegeben werden.

We recommend having contextIsolation enabled 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

Entfernt: `crashReporter.getCrashesDirectory()`

The crashReporter.getCrashesDirectory method has been removed. Usage should be replaced by app.getPath('crashDumps').

// 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 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 module.

// Veraltet in Electron 12:

Veraltet: `shell.moveItemToTrash()`

The synchronous shell.moveItemToTrash() has been replaced by the new, asynchronous shell.trashItem().

// Deprecated in Electron 12

Veraltet: `companyName` Argument, um `crashReporter.start()`

The companyName argument to crashReporter.start(), which was previously required, is now optional, and further, is deprecated. Um das gleiche Verhalten auf nicht veraltete Weise zu erhalten, können Sie einen companyName Wert in globalExtraübergeben.

// Deprecated in Electron 10
crashReporter.start({ companyName: 'Umbrella Corporation' })
// Replace with
crashReporter.start({ globalExtra: { _companyName: 'Umbrella Corporation' } })

Veraltet: `crashReporter.getCrashesDirectory()`

Die crashReporter.getCrashesDirectory Methode wurde veraltet. Usage should be replaced by app.getPath('crashDumps').

// 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 for more details.

Veraltet: `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.

Standardwert geändert: `enableRemoteModule` ist standardmäßig auf `false` eingestellt

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:

const w = new BrowserWindow({
  webPreferences: {
    enableRemoteModule: true
  }
})

We recommend moving away from the remote module.

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.

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:

Entfernt: `webFrame.setLayoutZoomLevelLimits()`

Chromium hat die Unterstützung für das Ändern des Layout-Zoomniveaus entfernt und es übersteigt die Möglichkeiten von uns, dies zu pflegen. 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.

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.

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, 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.

// 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 nulls.
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 Uint8Arrays. You can convert a Uint8Array back to a Node.js Buffer by wrapping the underlying ArrayBuffer:

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.

Veraltet: `<webview>.getWebContents()`

This API is implemented using the remote module, which has both performance and security implications. Therefore its usage should be explicit.

// 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.

// 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())

Veraltet: `webFrame.setLayoutZoomLevelLimits()`

Chromium hat die Unterstützung für das Ändern des Layout-Zoomniveaus entfernt und es übersteigt die Möglichkeiten von uns, dies zu pflegen. 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.

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.

// Deprecated

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.

  })

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).

As an illustration, take a folder with this structure:

folder
├── file1
├── file2
└── file3

In Electron <=6, this would return a FileList with a File object for:

path/to/folder

In Electron 7, this now returns a FileList with a File object for:

/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 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
app.dock.show() #16904
contentTracing.getCategories() #16583
contentTracing.getTraceBufferUsage() #16600
contentTracing.startRecording() #16584

// API will be removed in v7.0 without replacement.

Geplante Bruch-API-Änderungen (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`

z.B. Re-enabling the webviewTag

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`

// Deprecated
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)

    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.

// 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.

// Deprecated
webContents.getZoomLevel((level) => {
  console.log(level)
})
// Replace with
const level = webContents.getZoomLevel()
console.log(level)

// Deprecated
webContents.getZoomFactor((factor) => {
  console.log(factor)
})
// Replace with
const factor = webContents.getZoomFactor()

`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 for more.

Duplicate ARM Assets

Each Electron release includes two identical ARM builds with slightly different filenames, like electron-v1.7.3-linux-arm.zip and electron-v1.7.3-linux-armv7l.zip. The asset with the v7l prefix was added to clarify to users which ARM version it supports, and to disambiguate it from future armv6l and arm64 assets that may be produced.

The file without the prefix is still being published to avoid breaking any setups that may be consuming it. Starting at 2.0, the unprefixed file will no longer be published.

For details, see 6986 and 7189.
