Критические изменения

Здесь будут описаны критические изменения, а также будут добавлены предупреждения об устаревших функциях в JS коде, где это возможно, по крайней мере перед тем, как изменения будут сделаны в одной мажорной версии.

Типы критических изменений

В этом документе используется следующее соглашение для классификации критических изменений:

• Изменение API: API был изменен таким образом, что код, который не был обновлен, гарантировано бросит исключение.
• Изменение поведения: Поведение Electron было изменено, но не обязательно появление исключений.
• Изменено значение по-умолчанию: Код, работа которого зависит от старого значения по-умолчанию, может сломаться, не обязательно кидая исключение. Старое поведение можно восстановить, если явно указать значение.
• Устарело: API был помечен как устаревший. API продолжит функционировать, но будет появляться предупреждающее сообщение о том, что API будет удален в будущем релизе.
• Удалено: API или функция была удалена и больше не поддерживается Electron.

Запланированные критические изменения API (27.0)

Removed: macOS 10.13 / 10.14 support

macOS 10.13 (High Sierra) and macOS 10.14 (Mojave) are no longer supported by Chromium.

Older versions of Electron will continue to run on these operating systems, but macOS 10.15 (Catalina) or later will be required to run Electron v27.0.0 and higher.

Запланированные критические изменения API (26.0)

Устарело: webContents.getPrinters

Метод webContents.getPrinters устарел. Используйте вместо него webContents.getPrintersAsync.

const w = new BrowserWindow({ show: false })

// Устарело
console.log(w.webContents.getPrinters())
// Заменить на
w.webContents.getPrintersAsync().then((printers) => {
  console.log(printers)
})

Устарело: systemPreferences.{get,set}AppLevelAppearance и systemPreferences.appLevelAppearance

Методы systemPreferences.getAppLevelAppearance и systemPreferences.setAppLevelAppearance устарели, так же как и свойство systemPreferences.appLevelAppearance. Вместо этого используйте модуль nativeTheme.

// Устарело
systemPreferences.getAppLevelAppearance()
// Заменить на
nativeTheme.shouldUseDarkColors

// Устарело
systemPreferences.appLevelAppearance
// Заменить на
nativeTheme.shouldUseDarkColors

// Устарело
systemPreferences.setAppLevelAppearance('dark')
// Заменить на
nativeTheme.themeSource = 'dark'

Устарело: значение alternate-selected-control-text для systemPreferences.getColor

Значение alternate-selected-control-text для systemPreferences.getColor устарело. Вместо него используйте selected-content-background.

// Устарело
systemPreferences.getColor('alternate-selected-control-text')
// Заменить на
systemPreferences.getColor('selected-content-background')

Запланированные критические изменения API (25.0)

Obsoleto: protocol.{register,intercept}{Buffer,String,Stream,File,Http}Protocol

Методы protocol.register*Protocol и protocol.intercept*Protocol заменены на protocol.handle.

The new method can either register a new protocol or intercept an existing protocol, and responses can be of any type.

// Устарело в Electron 25
protocol.registerBufferProtocol('some-protocol', () => {
  callback({ mimeType: 'text/html', data: Buffer.from('<h5>Response</h5>') })
})

// Заменить на
protocol.handle('some-protocol', () => {
  return new Response(
    Buffer.from('<h5>Response</h5>'), // Could also be a string or ReadableStream.
    { headers: { 'content-type': 'text/html' } }
  )
})

// Устарело в Electron 25
protocol.registerHttpProtocol('some-protocol', () => {
  callback({ url: 'https://electronjs.org' })
})

// Заменить на
protocol.handle('some-protocol', () => {
  return net.fetch('https://electronjs.org')
})

// Deprecated in Electron 25
protocol.registerFileProtocol('some-protocol', () => {
  callback({ filePath: '/path/to/my/file' })
})

// Replace with
protocol.handle('some-protocol', () => {
  return net.fetch('file:///path/to/my/file')
})

Obsoleto: BrowserWindow.setTrafficLightPosition(position)

BrowserWindow.setTrafficLightPosition(position) has been deprecated, the BrowserWindow.setWindowButtonPosition(position) API should be used instead which accepts null instead of { x: 0, y: 0 } to reset the position to system default.

// Deprecated in Electron 25
win.setTrafficLightPosition({ x: 10, y: 10 })
win.setTrafficLightPosition({ x: 0, y: 0 })

// Replace with
win.setWindowButtonPosition({ x: 10, y: 10 })
win.setWindowButtonPosition(null)

Obsoleto: BrowserWindow.getTrafficLightPosition()

BrowserWindow.getTrafficLightPosition() has been deprecated, the BrowserWindow.getWindowButtonPosition() API should be used instead which returns null instead of { x: 0, y: 0 } when there is no custom position.

// Deprecated in Electron 25
const pos = win.getTrafficLightPosition()
if (pos.x === 0 && pos.y === 0) {
  // No custom position.
}

// Replace with
const ret = win.getWindowButtonPosition()
if (ret === null) {
  // No custom position.
}

Запланированные критические изменения API (24.0)

Изменения в API: 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.

Updated Behavior:

// 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 }
})

Previous Behavior (on 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 }
})

Запланированные критические изменения API (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()
  }
})

Удален: webContents.incrementCapturerCount(stayHidden, stayAwake)

The webContents.incrementCapturerCount(stayHidden, stayAwake) function has been removed. It is now automatically handled by webContents.capturePage when a page capture completes.

const w = new BrowserWindow({ show: false })

// Removed in Electron 23
w.webContents.incrementCapturerCount()
w.capturePage().then(image => {
  console.log(image.toDataURL())
  w.webContents.decrementCapturerCount()
})

// Replace with
w.capturePage().then(image => {
  console.log(image.toDataURL())
})

Удален: webContents.decrementCapturerCount(stayHidden, stayAwake)

The webContents.decrementCapturerCount(stayHidden, stayAwake) function has been removed. It is now automatically handled by webContents.capturePage when a page capture completes.

const w = new BrowserWindow({ show: false })

// Removed in Electron 23
w.webContents.incrementCapturerCount()
w.capturePage().then(image => {
  console.log(image.toDataURL())
  w.webContents.decrementCapturerCount()
})

// Replace with
w.capturePage().then(image => {
  console.log(image.toDataURL())
})

Запланированные критические изменения API (22.0)

Obsoleto: webContents.incrementCapturerCount(stayHidden, stayAwake)

// Removed in Electron 23
w.webContents.incrementCapturerCount()
w.capturePage().then(image => {
  console.log(image.toDataURL())

})

// Replace with
w.capturePage().then(image => {
  console.log(image.toDataURL())
})

Removed: WebContents new-window event

The new-window event of WebContents has been removed. Заменяется на webContents.setWindowOpenHandler().

// Removed in Electron 22
webContents.on('new-window', (event) => {
  event.preventDefault()
})

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

Removed: <webview> new-window event

The new-window event of <webview> has been removed. There is no direct replacement.

// Removed in Electron 22
webview.addEventListener('new-window', (event) => {})

Planned Breaking API Changes (21.0)

Comportement modifié: Cage mémoire V8 activée

The V8 memory cage has been enabled, which has implications for native modules which wrap non-V8 memory with ArrayBuffer or Buffer. See the blog post about the V8 memory cage for more details.

API Changed: webContents.printToPDF()

webContents.printToPDF() has been modified to conform to Page.printToPDF in the Chrome DevTools Protocol. This has been changes in order to address changes upstream that made our previous implementation untenable and rife with bugs.

Planned Breaking API Changes (20.0)

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.

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.

API Changed: 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.

Planned Breaking API Changes (19.0)

Removed: IA32 Linux binaries

This is a result of Chromium 102.0.4999.0 dropping support for IA32 Linux. This concludes the removal of support for IA32 Linux.

Planned Breaking API Changes (18.0)

Удален: 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. Начиная с Electron 15, nativeWindowOpen включен по умолчанию.

См. документацию по window.open в Electron для более подробной информации.

Planned Breaking API Changes (17.0)

Удалено: desktopCapturer.getSources в рендере

API desktopCapturer.getSources теперь доступен только в основном процессе. Это было изменено для того, чтобы улучшить стандартную безопасность приложений Electron приложения.

Если вам нужна эта функциональность, ее можно заменить следующим образом:

// 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)
}

Однако следует рассмотреть возможность дальнейшего ограничения информации, возвращаемой в рендереру; например, отображать пользователю селектор источников и только возвращать только выбранный источник.

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. Начиная с Electron 15, nativeWindowOpen включен по умолчанию.

См. документацию по window.open в Electron для более подробной информации.

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 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.

См. документацию по window.open в Electron для более подробной информации.

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 module.

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

// Replace with:
const { BrowserWindow } = require('@electron/remote')

// In the main process:
require('@electron/remote/main').initialize()

Удален: 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.

Для подробностей см. #18397.

Removed: Browser Window Affinity

Параметр affinity при создании нового BrowserWindow будет удален в рамках нашего плана для более тесной связи с моделью процесса Chrome в целях безопасности, производительность и лучшей поддержки.

Для подробностей см. #18397.

Изменения в API: window.open()

Необязательный параметр frameName больше не устанавливает название окна. Теперь это следует спецификации, описанной в документации в соответствии с параметром windowName.

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

Удален: worldSafeExecuteJavaScript

В Electron 14 worldSafeExecuteJavaScript будет удален. Альтернатива отсутствует, пожалуйста, убедитесь, что в вашем коде данный параметр включен. Он был включен в Electron по умолчанию 12.

На вас повлияет это изменение, если вы используете либо webFrame.executeJavaScript или webFrame.executeJavaScriptInIsolatedWorld. 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.

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:

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

Удален: 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.

// 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)

Первым параметром handler был ранее всегда webContents, теперь он иногда может быть null. Вы должны использовать requestingOrigin, embeddingOrigin и securityOrigin свойства для правильного ответа на проверку. Так как webContents может быть null больше, на него нельзя полагаться.

// Старый код
session.setPermissionCheckHandler((webContents, permission) => {
  if (webContents.getURL().startsWith('https://google. om/') && permission === 'notification') {
    return true
  }
  возвращает false
})

// Заменить на
сессию. etPermissionCheckHandler((webContents, permission, requestingOrigin) => {
  if (new URL(requestingOrigin). ostname === 'google.com' && permission === 'notification') {
    return true
  }
  возвращает false
})

Removed: shell.moveItemToTrash()

Удален устаревший синхронный shell.moveItemToTrash() API. Вместо этого используйте асинхронный shell.trashItem().

// Удалён в Electron 13
shell.moveItemToTrash(path)
// Замена на
shell.trashItem(path).then(/* ... */)

Удалено: BrowserWindow API расширений

Удалено устаревшее API расширений:

• BrowserWindow.addExtension(path)
• BrowserWindow.addDevToolsExtension(path)
• BrowserWindow.removeExtension(name)
• BrowserWindow.removeDevToolsExtension(name)
• BrowserWindow.getExtensions()
• BrowserWindow.getDevToolsExtensions()

Использовать API сессии:

• ses.loadExtension(path)
• ses.removeExtension(extension_id)
• ses.getAllExtensions()

// Удален в Electron 13
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Заменить
session.defaultSession.loadExtension(path)

// Удален в Electron 13
BrowserWindow.addExtension(path)
BrowserWindow.addDevToolsExtension(path)
// Заменить
session.defaultSession.loadExtension(path)

// Удален в Electron 13
BrowserWindow.getExtensions()
BrowserWindow.getDevToolsExtensions()
// Заменить
session.defaultSession.getAllExtensions()

Удалено: методы в systemPreferences

Следующие systemPreferences были устаревшими:

• systemPreferences.isDarkMode()
• systemPreferences.isvertedColorScheme()
• systemPreferences.isHighContrastColorScheme()

Используйте следующие свойства nativeTheme вместо этого:

• nativeTheme.shouldUseDarkColors
• nativeTheme.shouldUseInvertedColorScheme
• nativeTheme.shouldUseHighContrastColors

// Удалён в Electron 13
systemPreferences.isDarkMode()
// Заменить на
nativeTheme.shouldUseDarkColors

// Удалён в Electron 13
systemPreferences. sInvertedColorScheme()
// Заменить на
nativeTheme.shouldUseInvertedColorScheme

// Удалено в Electron 13
systemPreferences.isHighContrastColorScheme()
// Заменить на
nativeTheme.shouldUseHighContrastColors

Устарело: WebContents new-window событие

Событие new-window сетевого контента является устаревшим. Заменяется на webContents.setWindowOpenHandler().

// Устарел в Electron 13
webContents.on('new-window', (event) => {
  событие. reventDefault()
})

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

Запланированные критические изменения API (12.0)

Удалено: Поддержка Pepper Flash

Chromium удалил поддержку Flash, и поэтому мы должны следовать этому примеру. Смотрите Chromium Flash Roadmap для получения более подробной информации.

Default Changed: worldSafeExecuteJavaScript defaults to true

В Electron 12, worldSafeExecuteJavaScript будет включен по умолчанию. Чтобы восстановить предыдущее поведение, в WebPreferences должен быть определен worldSafeExecuteJavaScript: false. Обратите внимание, что установливать этого параметр в false небезопасно.

This option will be removed in Electron 14 so please migrate your code to support the default value.

Default Changed: contextIsolation defaults to true

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.

Подробнее см.: https://github.com/electron/electron/issues/23506

Удален: 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
• вылетать Reporter.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.

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

// Replace with:
const { BrowserWindow } = require('@electron/remote')

// In the main process:
require('@electron/remote/main').initialize()

Устарело: shell.moveItemToTrash()

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

// Deprecated in Electron 12
shell.moveItemToTrash(path)

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.

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

Obsoleto: crashReporter.getCrashesDirectory()

Метод crashReporter.getCrashesDirectory устарел. 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
• вылетать Reporter.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.

Устарело: 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.

Изменение значения по-умолчанию: enableRemoteModule изменено на 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:

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.

Для подробностей см. #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()

Removed: <webview>.getWebContents()

Удален этот API, устаревший в Electron 8.0.

// Удален в Electron 9.0
webview.getWebContents()
// Замена на
const { remote } = require('electron')
remote.webContents.fromId(webview.getWebContentsId())

Удален: 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.

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.

Запланированные критические изменения API (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, 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.

Устарело: <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())

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.

Deprecated events in systemPreferences

The following systemPreferences events have been deprecated:

• inverted-color-scheme-changed

Use the new updated event on the nativeTheme module instead.

// Deprecated
systemPreferences.on('inverted-color-scheme-changed', () => { /* ... */ })
systemPreferences.on('high-contrast-color-scheme-changed', () => { /* ... */ })

// Replace with
nativeTheme.on('updated', () => { /* ... */ })

Deprecated: methods in systemPreferences

Deprecated: https://atom.io/download/electron

Replace with: https://electronjs.org/headers

API Changed: session.clearAuthCache() no longer accepts options

session.clearAuthCache API больше не принимает параметры для очистки, а вместо этого безоговорочно очищает весь кэш.

// Устарело
session.clearAuthCache({ type: 'password' })
// Заменить на

API Changed: powerMonitor.querySystemIdleState is now powerMonitor.getSystemIdleState

// 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

// Removed in Electron 7.0

// Replace with synchronous API
const idleTime = powerMonitor.getSystemIdleTime()

API Changed: webFrame.setIsolatedWorldInfo replaces separate methods

// Удалено в Electron 7.0
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)
webFrame.setIsolatedWorldHumanReadableName(worldId, name)
webFrame.setIsolatedWorldSecurityOrigin(worldId, securityOrigin)
// Заменить на

  worldId,
  {
    securityOrigin: 'some_origin',

    csp: 'content_security_policy'
  })

Removed: marked property on getBlinkMemoryInfo

Это свойство было удалено в Chromium 77, и как таковое больше не доступно.

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

• webFrame.executeJavaScript() #17312
• webFrame.executeJavaScriptInIsolatedWorld() #17312
• webviewTag.executeJavaScript() #17312
• win.capturePage() #15743

These functions now have two forms, synchronous and Promise-based asynchronous:

• dialog.showMessageBox()/dialog.showMessageBoxSync() #17298
• dialog.showOpenDialog()/dialog.showOpenDialogSync() #16973
• dialog.showSaveDialog()/dialog.showSaveDialogSync() #17054

Дублированные ARM ресурсы

Каждый выпуск Electron включает в себя две идентичные сборки ARM с немного разными именами файлов, такие как electron-v1.7.3-linux-arm.zip и electron-v1.7.3-linux-armv7l.zip. Ресурс с префиксом v7l был добавлен, чтобы уточнить для пользователей, какую версию ARM он поддерживает, и чтобы исключить их в будущих ресурсах armv6l и arm64, которые могут быть произведены.

Файл без префикса по-прежнему публикуется, чтобы избежать нарушения любых настроек, которые могут его использовать. Начиная с версии 2.0, файл без префикса более не будет публиковаться.

Для подробностей см. 6986 и 7189.
