# 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 (23.0)
|
|
|
|
### 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](api/web-contents.md#event-input-event) on WebContents.
|
|
|
|
```js
|
|
// 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()
|
|
}
|
|
})
|
|
```
|
|
|
|
### Removed: `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.
|
|
|
|
```js
|
|
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())
|
|
})
|
|
```
|
|
|
|
### Removed: `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.
|
|
|
|
```js
|
|
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())
|
|
})
|
|
```
|
|
|
|
## Planned Breaking API Changes (22.0)
|
|
|
|
### Deprecated: `webContents.incrementCapturerCount(stayHidden, stayAwake)`

|
|
It is now automatically handled by `webContents.capturePage` when a page capture completes.
|
|
|
|
```js

|
|
})
|
|
```
|
|
|
|
### Removed: WebContents `new-window` event
|
|
|
|
The `new-window` event of WebContents has been removed. It is replaced by [`webContents.setWindowOpenHandler()`](api/web-contents.md#contentssetwindowopenhandlerhandler).
|
|
|
|
```js
|
|
// Removed in Electron 22
|
|
webContents.on('new-window', (event) => {
|
|
event.preventDefault()
|
|
})
|
|
|
|
// Replace with
|
|
webContents.setWindowOpenHandler((details) => {
|
|
return { action: 'deny' }
|
|
})
|
|
```
|
|
|
|
### Deprecated: BrowserWindow `scroll-touch-*` events
|
|
|
|
The `scroll-touch-begin`, `scroll-touch-end` and `scroll-touch-edge` events on
|
|
BrowserWindow are deprecated. Instead, use the newly available [`input-event`
|
|
event](api/web-contents.md#event-input-event) on WebContents.
|
|
|
|
```js
|
|
// Deprecated
|
|
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()
|
|
}
|
|
})
|
|
```
|
|
|
|
## Planned Breaking API Changes (21.0)
|
|
|
|
### Behavior Changed: V8 Memory Cage enabled
|
|
|
|
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](https://www.electronjs.org/blog/v8-memory-cage) for
|
|
more details.
|
|
|
|
### API Changed: `webContents.printToPDF()`
|
|
|
|
`webContents.printToPDF()` has been modified to conform to [`Page.printToPDF`](https://chromedevtools.github.io/devtools-protocol/tot/Page/#method-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.
|
|
|
|
**Arguments Changed**
|
|
|
|
* `pageRanges`
|
|
|
|
**Arguments Removed**
|
|
|
|
* `printSelectionOnly`
|
|
* `marginsType`
|
|
* `headerFooter`
|
|
* `scaleFactor`
|
|
|
|
**Arguments Added**
|
|
|
|
* `headerTemplate`
|
|
* `footerTemplate`
|
|
* `displayHeaderFooter`
|
|
* `margins`
|
|
* `scale`
|
|
* `preferCSSPageSize`
|
|
|
|
```js
|
|
// Main process
|
|
const { webContents } = require('electron')
|
|
|
|
webContents.printToPDF({
|
|
landscape: true,
|
|
displayHeaderFooter: true,
|
|
printBackground: true,
|
|
scale: 2,
|
|
pageSize: 'Ledger',
|
|
margins: {
|
|
top: 2,
|
|
bottom: 2,
|
|
left: 2,
|
|
right: 2
|
|
},
|
|
pageRanges: '1-5, 8, 11-13',
|
|
headerTemplate: '<h1>Title</h1>',
|
|
footerTemplate: '<div><span class="pageNumber"></span></div>',
|
|
preferCSSPageSize: true
|
|
}).then(data => {
|
|
fs.writeFile(pdfPath, data, (error) => {
|
|
if (error) throw error
|
|
console.log(`Wrote PDF successfully to ${pdfPath}`)
|
|
})
|
|
}).catch(error => {
|
|
console.log(`Failed to write PDF to ${pdfPath}: `, error)
|
|
})
|
|
```
|
|
|
|
## 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.
|
|
|
|
### 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](api/web-frame-main.md)`, 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](#removed-ia32-linux-support).
|
|
|
|
## 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 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.
|
|

|
|
|
|
### 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:

|
## Planned Breaking API Changes (6.0)
|
|
|
|
### API Changed: `win.setMenu(null)` is now `win.removeMenu()`
|
|
|
|
```js
|
|
// Deprecated
|
|
win.setMenu(null)
|
|
// Replace with
|
|
win.removeMenu()
|

|
|
// Replace with
|
|
require('electron').remote.screen
|
|
```
|
|
|
|
### API Changed: `require()`ing node builtins in sandboxed renderers no longer implicitly loads the `remote` version
|
|
|
|
```js
|
|
// Deprecated
|
|
require('child_process')
|
|
// Replace with
|
|
require('electron').remote.require('child_process')

|
require('electron').remote.require('path')
|
|
```
|
|
|
|
### Deprecated: `powerMonitor.querySystemIdleState` replaced with `powerMonitor.getSystemIdleState`
|

```
|
|
|
|
Mixed-sandbox mode is now enabled by default.
|
|
|
|
### Deprecated: `Tray.setHighlightMode`
|
|
|
|
Under macOS Catalina our former Tray implementation breaks.
|
|
Apple's native substitute doesn't support changing the highlighting behavior.
|
|
|
|
```js
|
|
// Deprecated
|
|
tray.setHighlightMode(mode)
|
|
// API will be removed in v7.0 without replacement.
|
|
```
|
|
|
|
## Planned Breaking API Changes (5.0)
|
|
|
|
### Default Changed: `nodeIntegration` and `webviewTag` default to false, `contextIsolation` defaults to true
|
|
|
|
The following `webPreferences` option default values are deprecated in favor of the new defaults listed below.
|
|
|
|
| Property | Deprecated Default | New Default |
|
|
|----------|--------------------|-------------|
|
|
| `contextIsolation` | `false` | `true` |
|
|
| `nodeIntegration` | `true` | `false` |
|
|
| `webviewTag` | `nodeIntegration` if set else `true` | `false` |
|
|
|
|
E.g. Re-enabling the webviewTag
|
|
|
|
```js
|
|
const w = new BrowserWindow({
|
|
webPreferences: {
|
|
webviewTag: true
|
|
}
|
|
})
|
|
```
|
|
|
|
### Behavior Changed: `nodeIntegration` in child windows opened via `nativeWindowOpen`
|
|
|
|
Child windows opened with the `nativeWindowOpen` option will always have Node.js integration disabled, unless `nodeIntegrationInSubFrames` is `true`.
|
|
|
|
### API Changed: Registering privileged schemes must now be done before app ready
|
|
|
|
Renderer process APIs `webFrame.registerURLSchemeAsPrivileged` and `webFrame.registerURLSchemeAsBypassingCSP` as well as browser process API `protocol.registerStandardSchemes` have been removed.
|
|
A new API, `protocol.registerSchemesAsPrivileged` has been added and should be used for registering custom schemes with the required privileges. Custom schemes are required to be registered before app ready.
|
|
|
|
### Deprecated: `webFrame.setIsolatedWorld*` replaced with `webFrame.setIsolatedWorldInfo`
|
|
|
|
```js
|
|
// Deprecated
|
|
webFrame.setIsolatedWorldContentSecurityPolicy(worldId, csp)
|
|
webFrame.setIsolatedWorldHumanReadableName(worldId, name)
|
|
webFrame.setIsolatedWorldSecurityOrigin(worldId, securityOrigin)
|
|
// Replace with
|
|
webFrame.setIsolatedWorldInfo(
|
|
worldId,
|
|
{
|
|
securityOrigin: 'some_origin',
|
|
name: 'human_readable_name',
|
|
csp: 'content_security_policy'
|
|
})
|
|
```
|
|
|
|
### API Changed: `webFrame.setSpellCheckProvider` now takes an asynchronous callback
|
|
|
|
The `spellCheck` callback is now asynchronous, and `autoCorrectWord` parameter has been removed.
|
|
|
|
```js
|
|
// Deprecated
|
|
webFrame.setSpellCheckProvider('en-US', true, {
|
|
spellCheck: (text) => {
|
|
return !spellchecker.isMisspelled(text)
|
|
}
|
|
})
|
|
// Replace with
|
|
webFrame.setSpellCheckProvider('en-US', {
|
|
spellCheck: (words, callback) => {
|
|
callback(words.filter(text => spellchecker.isMisspelled(text)))
|
|
}
|
|
})
|
|
```
|
|
|
|
### API Changed: `webContents.getZoomLevel` and `webContents.getZoomFactor` are now synchronous
|
|
|
|
`webContents.getZoomLevel` and `webContents.getZoomFactor` no longer take callback parameters,
|
|
instead directly returning their number values.
|
|
|
|
```js
|
|
// Deprecated
|
|
webContents.getZoomLevel((level) => {
|
|
console.log(level)
|
|
})
|
|
// Replace with
|
|
const level = webContents.getZoomLevel()
|
|
console.log(level)
|
|
```
|
|
|
|
```js
|
|
// Deprecated
|
|
webContents.getZoomFactor((factor) => {
|
|
console.log(factor)
|
|
})
|
|
// Replace with
|
|
const factor = webContents.getZoomFactor()
|
|
console.log(factor)
|
|
```
|
|
|
|
## Planned Breaking API Changes (4.0)
|
|
|
|
The following list includes the breaking API changes made in Electron 4.0.
|
|
|
|
### `app.makeSingleInstance`
|
|
|
|
```js
|
|
// Deprecated
|
|
app.makeSingleInstance((argv, cwd) => {
|
|
/* ... */
|
|
})
|
|
// Replace with
|
|
app.requestSingleInstanceLock()
|
|
app.on('second-instance', (event, argv, cwd) => {
|
|
/* ... */
|
|
})
|
|
```
|
|
|
|
### `app.releaseSingleInstance`
|
|
|
|
```js
|
|
// Deprecated
|
|
app.releaseSingleInstance()
|
|
// Replace with
|
|
app.releaseSingleInstanceLock()
|
|
```
|
|
|
|
### `app.getGPUInfo`
|
|
|
|
```js
|
|
app.getGPUInfo('complete')
|
|
// Now behaves the same with `basic` on macOS
|
|
app.getGPUInfo('basic')
|
|
```
|
|
|
|
### `win_delay_load_hook`
|
|
|
|
When building native modules for windows, the `win_delay_load_hook` variable in
|
|
the module's `binding.gyp` must be true (which is the default). If this hook is
|
|
not present, then the native module will fail to load on Windows, with an error
|
|
message like `Cannot find module`. See the [native module
|
|
guide](/docs/tutorial/using-native-node-modules.md) for more.
|
|
|
|
### Removed: IA32 Linux support
|
|
|
|
Electron 18 will no longer run on 32-bit Linux systems. See [discontinuing support for 32-bit Linux](https://www.electronjs.org/blog/linux-32bit-support) for more information.

## 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()
|
|
// Replaced with
|
|
nativeImage.toPNG()
|
|
|
|
// Removed
|
|
nativeImage.toJpeg()
|
|
// Replaced with
|
|
nativeImage.toJPEG()
|
|
```
|
|
|
|
### `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)
|
|
```
|
|
|
|
### `webFrame`
|
|
|
|
```js
|
|
// Removed
|
|
webFrame.setZoomLevelLimits(1, 2)
|
|
// Replaced with
|
|
webFrame.setVisualZoomLevelLimits(1, 2)
|
|
```
|
|
|
|
### `<webview>`
|
|
|
|
```js
|
|
// Removed
|
|
webview.setZoomLevelLimits(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.
