[Bug]: build fails with `enable_electron_extensions=false`
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
25.8.2
### What operating system are you using?
Other Linux
### Operating System Version
openSUSE Tumbleweed
### What arch are you using?
ia32
### Last Known Working Electron version
_No response_
### Expected Behavior
I am trying to build Electron 25.8.2 with `enable_electron_extensions=false`.
### Actual Behavior
After fixing the <a href="https://gist.github.com/brjsp/b003b7062be0e080d55235cb8449b09e">obvious misguarded sections of code</a> we are left with several <a href="https://gist.github.com/brjsp/fe8e7342534ae347eeb3a66932e91ad2">linker errors</a>, mostly to stuff under //extensions/browser. I am not sure how to remove the dependency, as some of the uses of the offending types are in constructors eg. <a href=https://github.com/electron/electron/blob/v25.8.2/shell/browser/net/proxying_websocket.cc#L38>in proxying_websocket</a>.
### Testcase Gist URL
_No response_
### Additional Information
(Ignore the fact that the attached buildlog is from ix86 which is unsupported β I only used that architecture because it builds way faster and has clearer linker messages due to no LTO, the problem will be the same on any target)

### Electron Version
27.0.0-beta.7
### What operating system are you using?
Other Linux
### Operating System Version
Arch Linux: Linux jabba 6.4.12-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 24 Aug 2023 00:38:14 +0000 x86_64 GNU/Linux
### What arch are you using?
x64
### Last Known Working Electron version
26.2.2
### Expected Behavior
Web Crypto APIs should work in the worker.
### Actual Behavior
The call to `webcrypto.subtle.importKey(...)` fails in the worker on Electron 27.0.0-beta.7, but not on 26.2.2.
```
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'prototype')

```
### Testcase Gist URL
https://gist.github.com/threema-danilo/a53a94800e258a0c2a6adb67ac7bfa72
### Additional Information
Check out the fiddle. Start it and open the debug console. On Electron 26.2.2, it prints "AES key was loaded". On Electron 27.0.0-beta.7, it prints the exception.

### Electron Version
27.0.0-beta.7
### What operating system are you using?
Other Linux
### Operating System Version
Arch Linux: Linux jabba 6.4.12-arch1-1 #1 SMP PREEMPT_DYNAMIC Thu, 24 Aug 2023 00:38:14 +0000 x86_64 GNU/Linux
### What arch are you using?
x64
### Last Known Working Electron version
26.2.2
### Expected Behavior
Web Crypto APIs should work in the worker.
### Actual Behavior
The call to `webcrypto.subtle.importKey(...)` fails in the worker on Electron 27.0.0-beta.7, but not on 26.2.2.
```
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'prototype')
at isSharedArrayBuffer (node:internal/crypto/webidl:187:57)
at Object.BufferSource (node:internal/crypto/webidl:208:9)
at SubtleCrypto.importKey (node:internal/crypto/webcrypto:585:36)
at worker.js:6:18
```
### Testcase Gist URL
https://gist.github.com/threema-danilo/a53a94800e258a0c2a6adb67ac7bfa72
### Additional Information
Check out the fiddle. Start it and open the debug console. On Electron 26.2.2, it prints "AES key was loaded". On Electron 27.0.0-beta.7, it prints the exception.

[Bug]: BrowserWindow vibrancy doesn't apply without transparency
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.0-beta.2
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
27.0.0-beta.1
### Expected Behavior
Including `vibrancy: 'titlebar'` in BrowserWindow constructor options results in a window with background vibrancy.
### Actual Behavior
A white background is displayed without window vibrancy.
### Testcase Gist URL
https://gist.github.com/df665de6732858c3536198cef517fae9
### Additional Information
Regression from https://github.com/electron/electron/pull/39708

[Bug]: BrowserWindow vibrancy doesn't apply without transparency
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.0-beta.2
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
27.0.0-beta.1
### Expected Behavior
Including `vibrancy: 'titlebar'` in BrowserWindow constructor options results in a window with background vibrancy.
### Actual Behavior
A white background is displayed without window vibrancy.
### Testcase Gist URL
https://gist.github.com/df665de6732858c3536198cef517fae9
### Additional Information
Regression from https://github.com/electron/electron/pull/39708

const { app, BrowserWindow, BrowserView } = require("electron");
const init = () => {
let browserWindow = new BrowserWindow({
show: true,
});
browserWindow.loadURL("https://www.google.com");
let browserWindow2 = new BrowserWindow({
show: true,
});
browserWindow2.webContents.once("did-start-loading", () => {
browserWindow2.loadURL("https://www.google.com");
});
browserWindow2.loadURL("https://www.test.com");
};
app.on("ready", () => {
init();
});
```

### Expected Behavior
No crash
### Actual Behavior
In electron 5 it crashes with the following code: 2147483651
in electron 6 and 7 it just seems to hang but is basically dead
### To Reproduce
```
const { app, BrowserWindow, BrowserView } = require("electron");
const init = () => {
let browserWindow = new BrowserWindow({
show: true,
});
browserWindow.loadURL("https://www.google.com");
let browserWindow2 = new BrowserWindow({
show: true,
});
browserWindow2.webContents.once("did-start-loading", () => {
browserWindow2.loadURL("https://www.google.com");
});
browserWindow2.loadURL("https://www.test.com");
};
app.on("ready", () => {
init();
});
```

in electron 6 and 7 it just seems to hang but is basically dead
### To Reproduce
```
const { app, BrowserWindow, BrowserView } = require("electron");
const init = () => {
let browserWindow = new BrowserWindow({
show: true,
});
browserWindow.loadURL("https://www.google.com");
let browserWindow2 = new BrowserWindow({
show: true,
});
browserWindow2.webContents.once("did-start-loading", () => {
browserWindow2.loadURL("https://www.google.com");
});
browserWindow2.loadURL("https://www.test.com");
};
app.on("ready", () => {
init();
});
```

in electron 6 and 7 it just seems to hang but is basically dead
### To Reproduce
```
const { app, BrowserWindow, BrowserView } = require("electron");
const init = () => {
let browserWindow = new BrowserWindow({
show: true,
});
browserWindow.loadURL("https://www.google.com");
let browserWindow2 = new BrowserWindow({
show: true,
});
browserWindow2.webContents.once("did-start-loading", () => {
browserWindow2.loadURL("https://www.google.com");
});
browserWindow2.loadURL("https://www.test.com");
};
app.on("ready", () => {
init();
});
```

[Bug]: webContents.capturePage() returns empty image for fully occluded BrowserWindow on Windows
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a feature request that matches the one I want to file, without success.
### Electron Version
16.0.1
### What operating system are you using?
Windows
### Operating System Version
Windows 11 (10.0.22000.348)
### What arch are you using?
x64
### Last Known Working Electron version
10.4.7
### Expected Behavior
`webContents.capturePage()` should work for fully occluded BrowserWindow as the window is not minimized.
### Actual Behavior
`webContents.capturePage()` returns an empty `NativeImage` in this case.
### Testcase Gist URL
_No response_
### Additional Information
main.js for Fiddle
```js
const {app, BrowserWindow} = require('electron')
function createWindow () {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
})
setInterval(async () => {
const image = await mainWindow.capturePage();
console.log(image.getSize())
}, 1000);
mainWindow.loadFile('about:blank')
mainWindow.webContents.openDevTools({mode:'detach'})
}
app.whenReady().then(() => {
createWindow()
})
app.on('window-all-closed', function () {
app.quit()
})
```
to reproduce cover the BrowserWindow with the devtools, you'll see the image size being logged as `{ width: 0, height: 0 }`.
This is a regression from #27883, when I revert the change `webContents.capturePage()` is working correctly for occluded windows. Checking the visibility state does not seem correct to me as both occluded and minimized windows' webContents have visibilityState hidden.
The abandoned fix #27892 seems like a better option. Also according to the documentation of `CopyFromSurface`:
> // |callback| is guaranteed to be run, either synchronously or at some point
> // in the future (depending on the platform implementation and the current
> // state of the Surface). If the copy failed, the bitmap's drawsNothing()
> // method will return true.
> //
> // If the view's renderer is suspended (see WasOccluded()), this may result in
> // copying old data or failing.
> virtual void CopyFromSurface(
> const gfx::Rect& src_rect,
> const gfx::Size& output_size,
> base::OnceCallback<void(const SkBitmap&)> callback) = 0;

[Bug]: webContents.capturePage() returns empty image for fully occluded BrowserWindow on Windows
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a feature request that matches the one I want to file, without success.
### Electron Version
16.0.1
### What operating system are you using?
Windows
### Operating System Version
Windows 11 (10.0.22000.348)
### What arch are you using?
x64
### Last Known Working Electron version
10.4.7
### Expected Behavior
`webContents.capturePage()` should work for fully occluded BrowserWindow as the window is not minimized.
### Actual Behavior
`webContents.capturePage()` returns an empty `NativeImage` in this case.
### Testcase Gist URL
_No response_
### Additional Information
main.js for Fiddle
```js
const {app, BrowserWindow} = require('electron')
function createWindow () {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
})
setInterval(async () => {
const image = await mainWindow.capturePage();
console.log(image.getSize())
}, 1000);
mainWindow.loadFile('about:blank')
mainWindow.webContents.openDevTools({mode:'detach'})
}
app.whenReady().then(() => {
createWindow()
})
app.on('window-all-closed', function () {
app.quit()
})
```
to reproduce cover the BrowserWindow with the devtools, you'll see the image size being logged as `{ width: 0, height: 0 }`.
This is a regression from #27883, when I revert the change `webContents.capturePage()` is working correctly for occluded windows. Checking the visibility state does not seem correct to me as both occluded and minimized windows' webContents have visibilityState hidden.
The abandoned fix #27892 seems like a better option. Also according to the documentation of `CopyFromSurface`:
> // |callback| is guaranteed to be run, either synchronously or at some point
> // in the future (depending on the platform implementation and the current
> // state of the Surface). If the copy failed, the bitmap's drawsNothing()
> // method will return true.
> //
> // If the view's renderer is suspended (see WasOccluded()), this may result in
> // copying old data or failing.
> virtual void CopyFromSurface(
> const gfx::Rect& src_rect,
> const gfx::Size& output_size,
> base::OnceCallback<void(const SkBitmap&)> callback) = 0;

[Bug]: webContents.capturePage() returns empty image for fully occluded BrowserWindow on Windows
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a feature request that matches the one I want to file, without success.
### Electron Version
16.0.1
### What operating system are you using?
Windows
### Operating System Version
Windows 11 (10.0.22000.348)
### What arch are you using?
x64
### Last Known Working Electron version
10.4.7
### Expected Behavior
`webContents.capturePage()` should work for fully occluded BrowserWindow as the window is not minimized.
### Actual Behavior
`webContents.capturePage()` returns an empty `NativeImage` in this case.
### Testcase Gist URL
_No response_
### Additional Information
main.js for Fiddle
```js
const {app, BrowserWindow} = require('electron')
function createWindow () {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
})
setInterval(async () => {
const image = await mainWindow.capturePage();
console.log(image.getSize())
}, 1000);
mainWindow.loadFile('about:blank')
mainWindow.webContents.openDevTools({mode:'detach'})
}
app.whenReady().then(() => {
createWindow()
})
app.on('window-all-closed', function () {
app.quit()
})
```
to reproduce cover the BrowserWindow with the devtools, you'll see the image size being logged as `{ width: 0, height: 0 }`.
This is a regression from #27883, when I revert the change `webContents.capturePage()` is working correctly for occluded windows. Checking the visibility state does not seem correct to me as both occluded and minimized windows' webContents have visibilityState hidden.
The abandoned fix #27892 seems like a better option. Also according to the documentation of `CopyFromSurface`:
> // |callback| is guaranteed to be run, either synchronously or at some point
> // in the future (depending on the platform implementation and the current
> // state of the Surface). If the copy failed, the bitmap's drawsNothing()
> // method will return true.
> //
> // If the view's renderer is suspended (see WasOccluded()), this may result in
> // copying old data or failing.
> virtual void CopyFromSurface(
> const gfx::Rect& src_rect,
> const gfx::Size& output_size,
> base::OnceCallback<void(const SkBitmap&)> callback) = 0;

[Bug]: webContents.capturePage() returns empty image for fully occluded BrowserWindow on Windows
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a feature request that matches the one I want to file, without success.
### Electron Version
16.0.1
### What operating system are you using?
Windows
### Operating System Version
Windows 11 (10.0.22000.348)
### What arch are you using?
x64
### Last Known Working Electron version
10.4.7
### Expected Behavior
`webContents.capturePage()` should work for fully occluded BrowserWindow as the window is not minimized.
### Actual Behavior
`webContents.capturePage()` returns an empty `NativeImage` in this case.
### Testcase Gist URL
_No response_
### Additional Information
main.js for Fiddle
```js
const {app, BrowserWindow} = require('electron')
function createWindow () {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
})
setInterval(async () => {
const image = await mainWindow.capturePage();
console.log(image.getSize())
}, 1000);
mainWindow.loadFile('about:blank')
mainWindow.webContents.openDevTools({mode:'detach'})
}
app.whenReady().then(() => {
createWindow()
})
app.on('window-all-closed', function () {
app.quit()
})
```
to reproduce cover the BrowserWindow with the devtools, you'll see the image size being logged as `{ width: 0, height: 0 }`.
This is a regression from #27883, when I revert the change `webContents.capturePage()` is working correctly for occluded windows. Checking the visibility state does not seem correct to me as both occluded and minimized windows' webContents have visibilityState hidden.
The abandoned fix #27892 seems like a better option. Also according to the documentation of `CopyFromSurface`:
> // |callback| is guaranteed to be run, either synchronously or at some point
> // in the future (depending on the platform implementation and the current
> // state of the Surface). If the copy failed, the bitmap's drawsNothing()
> // method will return true.
> //
> // If the view's renderer is suspended (see WasOccluded()), this may result in
> // copying old data or failing.
> virtual void CopyFromSurface(
> const gfx::Rect& src_rect,
> const gfx::Size& output_size,
> base::OnceCallback<void(const SkBitmap&)> callback) = 0;

[Bug]: desktopCapturer source IDs are valid for a single use on Wayland
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.0-beta.9
### What operating system are you using?
Other Linux
### Operating System Version
Fedora Workstation 39
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
1. Get a source ID from desktopCapturer
2. Display the stream using getUserMedia
3. Stop the stream
4. Display the stream again using getUserMedia
### Actual Behavior
XDG desktop portal permission dialog appears again
### Testcase Gist URL
https://gist.github.com/aiddya/cfd89d040661e0553425e4203ce4512b
### Additional Information
The fiddle has a timeout function that displays the stream after 10 seconds. So the steps to test using the fiddle boil down to: select a source, preview it, stop it and then wait 10 seconds.

### Operating System Version
13.5
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
Prior to this CL: https://github.com/electron/electron/pull/39944
### Expected Behavior
Message ports will be automatically closed after they are garbage collected
### Actual Behavior
Message ports do not automatically closed after they are garbage collected, and won't close unless close is explicitly called
### Testcase Gist URL
https://gist.github.com/VerteDinde/8caf3292beb8cd8168e776d194f2bc64
### Additional Information
Steps to Repro:
1. Load the above gist
2. Let garbage collection occur, or simulate garbage collection with "Collect Garbage"
3. Take a heap snapshot and search for "message port".
Upstream Chromium bug filed here: https://bugs.chromium.org/p/chromium/issues/detail?id=1487835
This can also be reproduced in Chrome Canary by doing the following:
1. Load Canary, open DevTools
2. Run the following in console:
```
(function () {
const { port2 } = new MessageChannel();
port2.start();
})()
```
3. Simulate garbage collection with "Collect Garbage"
4. Take a heap snapshot and search for "message port"

[Bug]: Message ports don't close after garbage collection
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
28.0.0 / main
### What operating system are you using?
macOS
### Operating System Version
13.5
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
Prior to this CL: https://github.com/electron/electron/pull/39944
### Expected Behavior
Message ports will be automatically closed after they are garbage collected
### Actual Behavior
Message ports do not automatically closed after they are garbage collected, and won't close unless close is explicitly called
### Testcase Gist URL
https://gist.github.com/VerteDinde/8caf3292beb8cd8168e776d194f2bc64
### Additional Information
Steps to Repro:
1. Load the above gist
2. Let garbage collection occur, or simulate garbage collection with "Collect Garbage"
3. Take a heap snapshot and search for "message port".
Upstream Chromium bug filed here: https://bugs.chromium.org/p/chromium/issues/detail?id=1487835
This can also be reproduced in Chrome Canary by doing the following:
1. Load Canary, open DevTools
2. Run the following in console:
```
(function () {
const { port2 } = new MessageChannel();
port2.start();
})()
```
3. Simulate garbage collection with "Collect Garbage"
4. Take a heap snapshot and search for "message port"

[Bug]: Area where traffic lights is rendered does not receive click events when app is fullscreened with titlebar hidden on macOS
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
26.1.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
N/A
### Expected Behavior
Hi there! Apologies if there is already an opened issue for this, I tried to look in the repo but could not find anything relevant.
As the title suggests, we're currently experiencing an issue in our Mac app, which uses a hidden titlebar and therefore renders the traffic lights inline in our app's header alongside clickable elements such as buttons and popovers, where the leftmost buttons are no longer clickable when the app is maximized.
In debugging this, I realized that those buttons (which we have set up to replace the position of where the traffic lights were in the maximized state) do not receive click events at all (e.g. I can't select them from the Chromium inspector and setting a debugger for `onclick` events in the DOM yields nothing when I click that region.
Other relevant information here is that our header which renders these buttons has `-webkit-app-region: drag` set (so it does not receive DOM click events as expected) but each individual button has `-webkit-app-region: no-drag` set to allow them to be clickable and otherwise work just fine when the app is not maximized and the buttons have not been rendered where the traffic lights were in the un-maximized state.
### Actual Behavior
As described above, the relevant two leftmost buttons in our draggable header (which have `no-drag` set) are clickable when rendered next to the traffic lights while the app is not maximized but no longer receive click events when they replace the traffic lights at the edge of the window when it is maximized.
See demo gif below:
### Testcase Gist URL
https://gist.github.com/sergeichestakov/c84835f4d80182744b99e837268edc7c
### Additional Information
Worth noting that we can only reproduce this so far in macOS Ventura (on an M1 Mac). We also tried macOS Big Sur (on an x86 Mac) but this bug does not reproduce there.
Also relevant, we initialize the BrowserWindow with the following options:
```typescript
const window = new BrowserWindow({
webPreferences: {
preload,
additionalArguments: [
`--app-version=${app.getVersion()}`,
`--platform=${process.platform}`,
],
webviewTag: true,
},
title,
icon,
minWidth: 720,
minHeight: 480,
backgroundColor,
autoHideMenuBar: true,
// on macOS:
titleBarStyle: 'hidden',
titleBarOverlay: { height: 48 },
trafficLightPosition: { x: 20, y: 16 },
});
```

[Bug]: Area where traffic lights is rendered does not receive click events when app is fullscreened with titlebar hidden on macOS
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
26.1.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
N/A
### Expected Behavior
Hi there! Apologies if there is already an opened issue for this, I tried to look in the repo but could not find anything relevant.
As the title suggests, we're currently experiencing an issue in our Mac app, which uses a hidden titlebar and therefore renders the traffic lights inline in our app's header alongside clickable elements such as buttons and popovers, where the leftmost buttons are no longer clickable when the app is maximized.
In debugging this, I realized that those buttons (which we have set up to replace the position of where the traffic lights were in the maximized state) do not receive click events at all (e.g. I can't select them from the Chromium inspector and setting a debugger for `onclick` events in the DOM yields nothing when I click that region.
Other relevant information here is that our header which renders these buttons has `-webkit-app-region: drag` set (so it does not receive DOM click events as expected) but each individual button has `-webkit-app-region: no-drag` set to allow them to be clickable and otherwise work just fine when the app is not maximized and the buttons have not been rendered where the traffic lights were in the un-maximized state.
### Actual Behavior
As described above, the relevant two leftmost buttons in our draggable header (which have `no-drag` set) are clickable when rendered next to the traffic lights while the app is not maximized but no longer receive click events when they replace the traffic lights at the edge of the window when it is maximized.
See demo gif below:
### Testcase Gist URL
https://gist.github.com/sergeichestakov/c84835f4d80182744b99e837268edc7c
### Additional Information
Worth noting that we can only reproduce this so far in macOS Ventura (on an M1 Mac). We also tried macOS Big Sur (on an x86 Mac) but this bug does not reproduce there.
Also relevant, we initialize the BrowserWindow with the following options:
```typescript
const window = new BrowserWindow({
webPreferences: {
preload,
additionalArguments: [
`--app-version=${app.getVersion()}`,
`--platform=${process.platform}`,
],
webviewTag: true,
},
title,
icon,
minWidth: 720,
minHeight: 480,
backgroundColor,
autoHideMenuBar: true,
// on macOS:
titleBarStyle: 'hidden',
titleBarOverlay: { height: 48 },
trafficLightPosition: { x: 20, y: 16 },
});
```

[Bug]: Area where traffic lights is rendered does not receive click events when app is fullscreened with titlebar hidden on macOS
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
26.1.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
N/A
### Expected Behavior
Hi there! Apologies if there is already an opened issue for this, I tried to look in the repo but could not find anything relevant.
As the title suggests, we're currently experiencing an issue in our Mac app, which uses a hidden titlebar and therefore renders the traffic lights inline in our app's header alongside clickable elements such as buttons and popovers, where the leftmost buttons are no longer clickable when the app is maximized.
In debugging this, I realized that those buttons (which we have set up to replace the position of where the traffic lights were in the maximized state) do not receive click events at all (e.g. I can't select them from the Chromium inspector and setting a debugger for `onclick` events in the DOM yields nothing when I click that region.
Other relevant information here is that our header which renders these buttons has `-webkit-app-region: drag` set (so it does not receive DOM click events as expected) but each individual button has `-webkit-app-region: no-drag` set to allow them to be clickable and otherwise work just fine when the app is not maximized and the buttons have not been rendered where the traffic lights were in the un-maximized state.
### Actual Behavior
As described above, the relevant two leftmost buttons in our draggable header (which have `no-drag` set) are clickable when rendered next to the traffic lights while the app is not maximized but no longer receive click events when they replace the traffic lights at the edge of the window when it is maximized.
See demo gif below:
### Testcase Gist URL
https://gist.github.com/sergeichestakov/c84835f4d80182744b99e837268edc7c
### Additional Information
Worth noting that we can only reproduce this so far in macOS Ventura (on an M1 Mac). We also tried macOS Big Sur (on an x86 Mac) but this bug does not reproduce there.
Also relevant, we initialize the BrowserWindow with the following options:
```typescript
const window = new BrowserWindow({
webPreferences: {
preload,
additionalArguments: [
`--app-version=${app.getVersion()}`,
`--platform=${process.platform}`,
],
webviewTag: true,
},
title,
icon,
minWidth: 720,
minHeight: 480,
backgroundColor,
autoHideMenuBar: true,
// on macOS:
titleBarStyle: 'hidden',
titleBarOverlay: { height: 48 },
trafficLightPosition: { x: 20, y: 16 },
});
```

[Bug]: Area where traffic lights is rendered does not receive click events when app is fullscreened with titlebar hidden on macOS
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
26.1.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
N/A
### Expected Behavior
Hi there! Apologies if there is already an opened issue for this, I tried to look in the repo but could not find anything relevant.
As the title suggests, we're currently experiencing an issue in our Mac app, which uses a hidden titlebar and therefore renders the traffic lights inline in our app's header alongside clickable elements such as buttons and popovers, where the leftmost buttons are no longer clickable when the app is maximized.
In debugging this, I realized that those buttons (which we have set up to replace the position of where the traffic lights were in the maximized state) do not receive click events at all (e.g. I can't select them from the Chromium inspector and setting a debugger for `onclick` events in the DOM yields nothing when I click that region.
Other relevant information here is that our header which renders these buttons has `-webkit-app-region: drag` set (so it does not receive DOM click events as expected) but each individual button has `-webkit-app-region: no-drag` set to allow them to be clickable and otherwise work just fine when the app is not maximized and the buttons have not been rendered where the traffic lights were in the un-maximized state.
### Actual Behavior
As described above, the relevant two leftmost buttons in our draggable header (which have `no-drag` set) are clickable when rendered next to the traffic lights while the app is not maximized but no longer receive click events when they replace the traffic lights at the edge of the window when it is maximized.
See demo gif below:
### Testcase Gist URL
https://gist.github.com/sergeichestakov/c84835f4d80182744b99e837268edc7c
### Additional Information
Worth noting that we can only reproduce this so far in macOS Ventura (on an M1 Mac). We also tried macOS Big Sur (on an x86 Mac) but this bug does not reproduce there.
Also relevant, we initialize the BrowserWindow with the following options:
```typescript
const window = new BrowserWindow({
webPreferences: {
preload,
additionalArguments: [
`--app-version=${app.getVersion()}`,
`--platform=${process.platform}`,
],
webviewTag: true,
},
title,
icon,
minWidth: 720,
minHeight: 480,
backgroundColor,
autoHideMenuBar: true,
// on macOS:
titleBarStyle: 'hidden',
titleBarOverlay: { height: 48 },
trafficLightPosition: { x: 20, y: 16 },
});
```

[Bug]: Area where traffic lights is rendered does not receive click events when app is fullscreened with titlebar hidden on macOS
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
26.1.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
N/A
### Expected Behavior
Hi there! Apologies if there is already an opened issue for this, I tried to look in the repo but could not find anything relevant.
As the title suggests, we're currently experiencing an issue in our Mac app, which uses a hidden titlebar and therefore renders the traffic lights inline in our app's header alongside clickable elements such as buttons and popovers, where the leftmost buttons are no longer clickable when the app is maximized.
In debugging this, I realized that those buttons (which we have set up to replace the position of where the traffic lights were in the maximized state) do not receive click events at all (e.g. I can't select them from the Chromium inspector and setting a debugger for `onclick` events in the DOM yields nothing when I click that region.
Other relevant information here is that our header which renders these buttons has `-webkit-app-region: drag` set (so it does not receive DOM click events as expected) but each individual button has `-webkit-app-region: no-drag` set to allow them to be clickable and otherwise work just fine when the app is not maximized and the buttons have not been rendered where the traffic lights were in the un-maximized state.
### Actual Behavior
As described above, the relevant two leftmost buttons in our draggable header (which have `no-drag` set) are clickable when rendered next to the traffic lights while the app is not maximized but no longer receive click events when they replace the traffic lights at the edge of the window when it is maximized.
See demo gif below:
### Testcase Gist URL
https://gist.github.com/sergeichestakov/c84835f4d80182744b99e837268edc7c
### Additional Information
Worth noting that we can only reproduce this so far in macOS Ventura (on an M1 Mac). We also tried macOS Big Sur (on an x86 Mac) but this bug does not reproduce there.
Also relevant, we initialize the BrowserWindow with the following options:
```typescript
const window = new BrowserWindow({
webPreferences: {
preload,
additionalArguments: [
`--app-version=${app.getVersion()}`,
`--platform=${process.platform}`,
],
webviewTag: true,
},
title,
icon,
minWidth: 720,
minHeight: 480,
backgroundColor,
autoHideMenuBar: true,
// on macOS:
titleBarStyle: 'hidden',
titleBarOverlay: { height: 48 },
trafficLightPosition: { x: 20, y: 16 },
});
```

[Bug]: Area where traffic lights is rendered does not receive click events when app is fullscreened with titlebar hidden on macOS
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
26.1.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
N/A
### Expected Behavior
Hi there! Apologies if there is already an opened issue for this, I tried to look in the repo but could not find anything relevant.
As the title suggests, we're currently experiencing an issue in our Mac app, which uses a hidden titlebar and therefore renders the traffic lights inline in our app's header alongside clickable elements such as buttons and popovers, where the leftmost buttons are no longer clickable when the app is maximized.
In debugging this, I realized that those buttons (which we have set up to replace the position of where the traffic lights were in the maximized state) do not receive click events at all (e.g. I can't select them from the Chromium inspector and setting a debugger for `onclick` events in the DOM yields nothing when I click that region.
Other relevant information here is that our header which renders these buttons has `-webkit-app-region: drag` set (so it does not receive DOM click events as expected) but each individual button has `-webkit-app-region: no-drag` set to allow them to be clickable and otherwise work just fine when the app is not maximized and the buttons have not been rendered where the traffic lights were in the un-maximized state.
### Actual Behavior
As described above, the relevant two leftmost buttons in our draggable header (which have `no-drag` set) are clickable when rendered next to the traffic lights while the app is not maximized but no longer receive click events when they replace the traffic lights at the edge of the window when it is maximized.
See demo gif below:
### Testcase Gist URL
https://gist.github.com/sergeichestakov/c84835f4d80182744b99e837268edc7c
### Additional Information
Worth noting that we can only reproduce this so far in macOS Ventura (on an M1 Mac). We also tried macOS Big Sur (on an x86 Mac) but this bug does not reproduce there.
Also relevant, we initialize the BrowserWindow with the following options:
```typescript
const window = new BrowserWindow({
webPreferences: {
preload,
additionalArguments: [
`--app-version=${app.getVersion()}`,
`--platform=${process.platform}`,
],
webviewTag: true,
},
title,
icon,
minWidth: 720,
minHeight: 480,
backgroundColor,
autoHideMenuBar: true,
// on macOS:
titleBarStyle: 'hidden',
titleBarOverlay: { height: 48 },
trafficLightPosition: { x: 20, y: 16 },
});
```

[Bug]: Area where traffic lights is rendered does not receive click events when app is fullscreened with titlebar hidden on macOS

### Electron Version
26.1.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.5.2
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
N/A
### Expected Behavior
Hi there! Apologies if there is already an opened issue for this, I tried to look in the repo but could not find anything relevant.
As the title suggests, we're currently experiencing an issue in our Mac app, which uses a hidden titlebar and therefore renders the traffic lights inline in our app's header alongside clickable elements such as buttons and popovers, where the leftmost buttons are no longer clickable when the app is maximized.
In debugging this, I realized that those buttons (which we have set up to replace the position of where the traffic lights were in the maximized state) do not receive click events at all (e.g. I can't select them from the Chromium inspector and setting a debugger for `onclick` events in the DOM yields nothing when I click that region.
Other relevant information here is that our header which renders these buttons has `-webkit-app-region: drag` set (so it does not receive DOM click events as expected) but each individual button has `-webkit-app-region: no-drag` set to allow them to be clickable and otherwise work just fine when the app is not maximized and the buttons have not been rendered where the traffic lights were in the un-maximized state.
### Actual Behavior
As described above, the relevant two leftmost buttons in our draggable header (which have `no-drag` set) are clickable when rendered next to the traffic lights while the app is not maximized but no longer receive click events when they replace the traffic lights at the edge of the window when it is maximized.
See demo gif below:
### Testcase Gist URL
https://gist.github.com/sergeichestakov/c84835f4d80182744b99e837268edc7c
### Additional Information
Worth noting that we can only reproduce this so far in macOS Ventura (on an M1 Mac). We also tried macOS Big Sur (on an x86 Mac) but this bug does not reproduce there.
Also relevant, we initialize the BrowserWindow with the following options:
```typescript
const window = new BrowserWindow({
webPreferences: {
preload,
additionalArguments: [
`--app-version=${app.getVersion()}`,
`--platform=${process.platform}`,
],
webviewTag: true,
},
title,
icon,
minWidth: 720,
minHeight: 480,
backgroundColor,
autoHideMenuBar: true,
// on macOS:
titleBarStyle: 'hidden',
titleBarOverlay: { height: 48 },
trafficLightPosition: { x: 20, y: 16 },
});
```

As described above, the relevant two leftmost buttons in our draggable header (which have `no-drag` set) are clickable when rendered next to the traffic lights while the app is not maximized but no longer receive click events when they replace the traffic lights at the edge of the window when it is maximized.
See demo gif below:
### Testcase Gist URL
https://gist.github.com/sergeichestakov/c84835f4d80182744b99e837268edc7c
### Additional Information
Worth noting that we can only reproduce this so far in macOS Ventura (on an M1 Mac). We also tried macOS Big Sur (on an x86 Mac) but this bug does not reproduce there.
Also relevant, we initialize the BrowserWindow with the following options:
```typescript
const window = new BrowserWindow({
webPreferences: {
preload,
additionalArguments: [
`--app-version=${app.getVersion()}`,
`--platform=${process.platform}`,
],
webviewTag: true,
},
title,
icon,
minWidth: 720,
minHeight: 480,
backgroundColor,
autoHideMenuBar: true,
// on macOS:
titleBarStyle: 'hidden',
titleBarOverlay: { height: 48 },
trafficLightPosition: { x: 20, y: 16 },
});
```

- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.
<img width="477" alt="image" src="https://user-images.githubusercontent.com/17458685/224576455-a9145dfc-7121-4097-9fe4-a472f0c2ead4.png">
### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

# app
> Control your application's event lifecycle.
Process: [Main](../glossary.md#main-process)
The following example shows how to quit the application when the last window is
closed:
```js
const { app } = require('electron')
app.on('window-all-closed', () => {
app.quit()
})
```
## Events
The `app` object emits the following events:
### Event: 'will-finish-launching'
Emitted when the application has finished basic startup. On Windows and Linux,
the `will-finish-launching` event is the same as the `ready` event; on macOS,
this event represents the `applicationWillFinishLaunching` notification of
`NSApplication`.
In most cases, you should do everything in the `ready` event handler.
### Event: 'ready'
Returns:
* `event` Event
* `launchInfo` Record<string, any> | [NotificationResponse](structures/notification-response.md) _macOS_
Emitted once, when Electron has finished initializing. On macOS, `launchInfo`
holds the `userInfo` of the [`NSUserNotification`](https://developer.apple.com/documentation/foundation/nsusernotification)
or information from [`UNNotificationResponse`](https://developer.apple.com/documentation/usernotifications/unnotificationresponse)
that was used to open the application, if it was launched from Notification Center.
You can also call `app.isReady()` to check if this event has already fired and `app.whenReady()`
to get a Promise that is fulfilled when Electron is initialized.
### Event: 'window-all-closed'
Emitted when all windows have been closed.
If you do not subscribe to this event and all windows are closed, the default
behavior is to quit the app; however, if you subscribe, you control whether the
app quits or not. If the user pressed `Cmd + Q`, or the developer called
`app.quit()`, Electron will first try to close all the windows and then emit the
`will-quit` event, and in this case the `window-all-closed` event would not be
emitted.
### Event: 'before-quit'
Returns:
* `event` Event
Emitted before the application starts closing its windows.
Calling `event.preventDefault()` will prevent the default behavior, which is
terminating the application.
**Note:** If application quit was initiated by `autoUpdater.quitAndInstall()`,
then `before-quit` is emitted _after_ emitting `close` event on all windows and
closing them.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'will-quit'
Returns:
* `event` Event
Emitted when all windows have been closed and the application will quit.
Calling `event.preventDefault()` will prevent the default behavior, which is
terminating the application.
See the description of the `window-all-closed` event for the differences between
the `will-quit` and `window-all-closed` events.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'quit'
Returns:
* `event` Event
* `exitCode` Integer
Emitted when the application is quitting.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'open-file' _macOS_
Returns:
* `event` Event
* `path` string
Emitted when the user wants to open a file with the application. The `open-file`
event is usually emitted when the application is already open and the OS wants
to reuse the application to open the file. `open-file` is also emitted when a
file is dropped onto the dock and the application is not yet running. Make sure
to listen for the `open-file` event very early in your application startup to
handle this case (even before the `ready` event is emitted).
You should call `event.preventDefault()` if you want to handle this event.
On Windows, you have to parse `process.argv` (in the main process) to get the
filepath.
### Event: 'open-url' _macOS_
Returns:
* `event` Event
* `url` string
Emitted when the user wants to open a URL with the application. Your application's
`Info.plist` file must define the URL scheme within the `CFBundleURLTypes` key, and
set `NSPrincipalClass` to `AtomApplication`.
As with the `open-file` event, be sure to register a listener for the `open-url`
event early in your application startup to detect if the application is being opened to handle a URL.
If you register the listener in response to a `ready` event, you'll miss URLs that trigger the launch of your application.
### Event: 'activate' _macOS_
Returns:
* `event` Event
* `hasVisibleWindows` boolean
Emitted when the application is activated. Various actions can trigger
this event, such as launching the application for the first time, attempting
to re-launch the application when it's already running, or clicking on the
application's dock or taskbar icon.
### Event: 'did-become-active' _macOS_
Returns:
* `event` Event
Emitted when the application becomes active. This differs from the `activate` event in
that `did-become-active` is emitted every time the app becomes active, not only
when Dock icon is clicked or application is re-launched. It is also emitted when a user
switches to the app via the macOS App Switcher.
### Event: 'did-resign-active' _macOS_
Returns:
* `event` Event
Emitted when the app is no longer active and doesnβt have focus. This can be triggered,
for example, by clicking on another application or by using the macOS App Switcher to
switch to another application.
### Event: 'continue-activity' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity on
another device.
* `details` Object
* `webpageURL` string (optional) - A string identifying the URL of the webpage accessed by the activity on another device, if available.
Emitted during [Handoff][handoff] when an activity from a different device wants
to be resumed. You should call `event.preventDefault()` if you want to handle
this event.
A user activity can be continued only in an app that has the same developer Team
ID as the activity's source app and that supports the activity's type.
Supported activity types are specified in the app's `Info.plist` under the
`NSUserActivityTypes` key.
### Event: 'will-continue-activity' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
Emitted during [Handoff][handoff] before an activity from a different device wants
to be resumed. You should call `event.preventDefault()` if you want to handle
this event.
### Event: 'continue-activity-error' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `error` string - A string with the error's localized description.
Emitted during [Handoff][handoff] when an activity from a different device
fails to be resumed.
### Event: 'activity-was-continued' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity.
Emitted during [Handoff][handoff] after an activity from this device was successfully
resumed on another one.
### Event: 'update-activity-state' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity.
Emitted when [Handoff][handoff] is about to be resumed on another device. If you need to update the state to be transferred, you should call `event.preventDefault()` immediately, construct a new `userInfo` dictionary and call `app.updateCurrentActivity()` in a timely manner. Otherwise, the operation will fail and `continue-activity-error` will be called.
### Event: 'new-window-for-tab' _macOS_
Returns:
* `event` Event
Emitted when the user clicks the native macOS new tab button. The new
tab button is only visible if the current `BrowserWindow` has a
`tabbingIdentifier`
### Event: 'browser-window-blur'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a [browserWindow](browser-window.md) gets blurred.
### Event: 'browser-window-focus'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a [browserWindow](browser-window.md) gets focused.
### Event: 'browser-window-created'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a new [browserWindow](browser-window.md) is created.
### Event: 'web-contents-created'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
Emitted when a new [webContents](web-contents.md) is created.
### Event: 'certificate-error'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `url` string
* `error` string - The error code
* `certificate` [Certificate](structures/certificate.md)
* `callback` Function
* `isTrusted` boolean - Whether to consider the certificate as trusted
* `isMainFrame` boolean
Emitted when failed to verify the `certificate` for `url`, to trust the
certificate you should prevent the default behavior with
`event.preventDefault()` and call `callback(true)`.
```js
const { app } = require('electron')
app.on('certificate-error', (event, webContents, url, error, certificate, callback) => {
if (url === 'https://github.com') {
// Verification logic.
event.preventDefault()
callback(true)
} else {
callback(false)
}
})
```
### Event: 'select-client-certificate'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `url` URL
* `certificateList` [Certificate[]](structures/certificate.md)
* `callback` Function
* `certificate` [Certificate](structures/certificate.md) (optional)
Emitted when a client certificate is requested.
The `url` corresponds to the navigation entry requesting the client certificate
and `callback` can be called with an entry filtered from the list. Using
`event.preventDefault()` prevents the application from using the first
certificate from the store.
```js
const { app } = require('electron')
app.on('select-client-certificate', (event, webContents, url, list, callback) => {
event.preventDefault()
callback(list[0])
})
```
### Event: 'login'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `authenticationResponseDetails` Object
* `url` URL
* `authInfo` Object
* `isProxy` boolean
* `scheme` string
* `host` string
* `port` Integer
* `realm` string
* `callback` Function
* `username` string (optional)
* `password` string (optional)
Emitted when `webContents` wants to do basic auth.
The default behavior is to cancel all authentications. To override this you
should prevent the default behavior with `event.preventDefault()` and call
`callback(username, password)` with the credentials.
```js
const { app } = require('electron')
app.on('login', (event, webContents, details, authInfo, callback) => {
event.preventDefault()
callback('username', 'secret')
})
```
If `callback` is called without a username or password, the authentication
request will be cancelled and the authentication error will be returned to the
page.
### Event: 'gpu-info-update'
Emitted whenever there is a GPU info update.
### Event: 'gpu-process-crashed' _Deprecated_
Returns:
* `event` Event
* `killed` boolean
Emitted when the GPU process crashes or is killed.
**Deprecated:** This event is superceded by the `child-process-gone` event
which contains more information about why the child process disappeared. It
isn't always because it crashed. The `killed` boolean can be replaced by
checking `reason === 'killed'` when you switch to that event.
### Event: 'renderer-process-crashed' _Deprecated_
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `killed` boolean
Emitted when the renderer process of `webContents` crashes or is killed.
**Deprecated:** This event is superceded by the `render-process-gone` event
which contains more information about why the render process disappeared. It
isn't always because it crashed. The `killed` boolean can be replaced by
checking `reason === 'killed'` when you switch to that event.
### Event: 'render-process-gone'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `details` [RenderProcessGoneDetails](structures/render-process-gone-details.md)
Emitted when the renderer process unexpectedly disappears. This is normally
because it was crashed or killed.
### Event: 'child-process-gone'
Returns:
* `event` Event
* `details` Object
* `type` string - Process type. One of the following values:
* `Utility`
* `Zygote`
* `Sandbox helper`
* `GPU`
* `Pepper Plugin`
* `Pepper Plugin Broker`
* `Unknown`
* `reason` string - The reason the child process is gone. Possible values:
* `clean-exit` - Process exited with an exit code of zero
* `abnormal-exit` - Process exited with a non-zero exit code
* `killed` - Process was sent a SIGTERM or otherwise killed externally
* `crashed` - Process crashed
* `oom` - Process ran out of memory
* `launch-failed` - Process never successfully launched
* `integrity-failure` - Windows code integrity checks failed
* `exitCode` number - The exit code for the process
(e.g. status from waitpid if on posix, from GetExitCodeProcess on Windows).
* `serviceName` string (optional) - The non-localized name of the process.
* `name` string (optional) - The name of the process.
Examples for utility: `Audio Service`, `Content Decryption Module Service`, `Network Service`, `Video Capture`, etc.
Emitted when the child process unexpectedly disappears. This is normally
because it was crashed or killed. It does not include renderer processes.
### Event: 'accessibility-support-changed' _macOS_ _Windows_
Returns:
* `event` Event
* `accessibilitySupportEnabled` boolean - `true` when Chrome's accessibility
support is enabled, `false` otherwise.
Emitted when Chrome's accessibility support changes. This event fires when
assistive technologies, such as screen readers, are enabled or disabled.
See https://www.chromium.org/developers/design-documents/accessibility for more
details.
### Event: 'session-created'
Returns:
* `session` [Session](session.md)
Emitted when Electron has created a new `session`.
```js
const { app } = require('electron')
app.on('session-created', (session) => {
console.log(session)
})
```
### Event: 'second-instance'
Returns:
* `event` Event
* `argv` string[] - An array of the second instance's command line arguments
* `workingDirectory` string - The second instance's working directory
* `additionalData` unknown - A JSON object of additional data passed from the second instance
This event will be emitted inside the primary instance of your application
when a second instance has been executed and calls `app.requestSingleInstanceLock()`.
`argv` is an Array of the second instance's command line arguments,
and `workingDirectory` is its current working directory. Usually
applications respond to this by making their primary window focused and
non-minimized.
**Note:** `argv` will not be exactly the same list of arguments as those passed
to the second instance. The order might change and additional arguments might be appended.
If you need to maintain the exact same arguments, it's advised to use `additionalData` instead.
**Note:** If the second instance is started by a different user than the first, the `argv` array will not include the arguments.
This event is guaranteed to be emitted after the `ready` event of `app`
gets emitted.
**Note:** Extra command line arguments might be added by Chromium,
such as `--original-process-start-time`.
## Methods
The `app` object has the following methods:
**Note:** Some methods are only available on specific operating systems and are
labeled as such.
### `app.quit()`
Try to close all windows. The `before-quit` event will be emitted first. If all
windows are successfully closed, the `will-quit` event will be emitted and by
default the application will terminate.
This method guarantees that all `beforeunload` and `unload` event handlers are
correctly executed. It is possible that a window cancels the quitting by
returning `false` in the `beforeunload` event handler.
### `app.exit([exitCode])`
* `exitCode` Integer (optional)
Exits immediately with `exitCode`. `exitCode` defaults to 0.
All windows will be closed immediately without asking the user, and the `before-quit`
and `will-quit` events will not be emitted.
### `app.relaunch([options])`
* `options` Object (optional)
* `args` string[] (optional)
* `execPath` string (optional)
Relaunches the app when current instance exits.
By default, the new instance will use the same working directory and command line
arguments with current instance. When `args` is specified, the `args` will be
passed as command line arguments instead. When `execPath` is specified, the
`execPath` will be executed for relaunch instead of current app.
Note that this method does not quit the app when executed, you have to call
`app.quit` or `app.exit` after calling `app.relaunch` to make the app restart.
When `app.relaunch` is called for multiple times, multiple instances will be
started after current instance exited.
An example of restarting current instance immediately and adding a new command
line argument to the new instance:
```js
const { app } = require('electron')
app.relaunch({ args: process.argv.slice(1).concat(['--relaunch']) })
app.exit(0)
```
### `app.isReady()`
Returns `boolean` - `true` if Electron has finished initializing, `false` otherwise.
See also `app.whenReady()`.
### `app.whenReady()`
Returns `Promise<void>` - fulfilled when Electron is initialized.
May be used as a convenient alternative to checking `app.isReady()`
and subscribing to the `ready` event if the app is not ready yet.
### `app.focus([options])`
* `options` Object (optional)
* `steal` boolean _macOS_ - Make the receiver the active app even if another app is
currently active.
On Linux, focuses on the first visible window. On macOS, makes the application
the active app. On Windows, focuses on the application's first window.
You should seek to use the `steal` option as sparingly as possible.
### `app.hide()` _macOS_
Hides all application windows without minimizing them.
### `app.isHidden()` _macOS_
Returns `boolean` - `true` if the applicationβincluding all of its windowsβis hidden (e.g. with `Command-H`), `false` otherwise.
### `app.show()` _macOS_
Shows application windows after they were hidden. Does not automatically focus
them.
### `app.setAppLogsPath([path])`
* `path` string (optional) - A custom path for your logs. Must be absolute.
Sets or creates a directory your app's logs which can then be manipulated with `app.getPath()` or `app.setPath(pathName, newPath)`.
Calling `app.setAppLogsPath()` without a `path` parameter will result in this directory being set to `~/Library/Logs/YourAppName` on _macOS_, and inside the `userData` directory on _Linux_ and _Windows_.
### `app.getAppPath()`
Returns `string` - The current application directory.
### `app.getPath(name)`
* `name` string - You can request the following paths by the name:
* `home` User's home directory.
* `appData` Per-user application data directory, which by default points to:
* `%APPDATA%` on Windows
* `$XDG_CONFIG_HOME` or `~/.config` on Linux
* `~/Library/Application Support` on macOS
* `userData` The directory for storing your app's configuration files, which
by default is the `appData` directory appended with your app's name. By
convention files storing user data should be written to this directory, and
it is not recommended to write large files here because some environments
may backup this directory to cloud storage.
* `sessionData` The directory for storing data generated by `Session`, such
as localStorage, cookies, disk cache, downloaded dictionaries, network
state, devtools files. By default this points to `userData`. Chromium may
write very large disk cache here, so if your app does not rely on browser
storage like localStorage or cookies to save user data, it is recommended
to set this directory to other locations to avoid polluting the `userData`
directory.
* `temp` Temporary directory.
* `exe` The current executable file.
* `module` The `libchromiumcontent` library.
* `desktop` The current user's Desktop directory.
* `documents` Directory for a user's "My Documents".
* `downloads` Directory for a user's downloads.
* `music` Directory for a user's music.
* `pictures` Directory for a user's pictures.
* `videos` Directory for a user's videos.
* `recent` Directory for the user's recent files (Windows only).
* `logs` Directory for your app's log folder.
* `crashDumps` Directory where crash dumps are stored.
Returns `string` - A path to a special directory or file associated with `name`. On
failure, an `Error` is thrown.
If `app.getPath('logs')` is called without called `app.setAppLogsPath()` being called first, a default log directory will be created equivalent to calling `app.setAppLogsPath()` without a `path` parameter.
### `app.getFileIcon(path[, options])`
* `path` string
* `options` Object (optional)
* `size` string
* `small` - 16x16
* `normal` - 32x32
* `large` - 48x48 on _Linux_, 32x32 on _Windows_, unsupported on _macOS_.
Returns `Promise<NativeImage>` - fulfilled with the app's icon, which is a [NativeImage](native-image.md).
Fetches a path's associated icon.
On _Windows_, there a 2 kinds of icons:
* Icons associated with certain file extensions, like `.mp3`, `.png`, etc.
* Icons inside the file itself, like `.exe`, `.dll`, `.ico`.
On _Linux_ and _macOS_, icons depend on the application associated with file mime type.
### `app.setPath(name, path)`
* `name` string
* `path` string
Overrides the `path` to a special directory or file associated with `name`.
If the path specifies a directory that does not exist, an `Error` is thrown.
In that case, the directory should be created with `fs.mkdirSync` or similar.
You can only override paths of a `name` defined in `app.getPath`.
By default, web pages' cookies and caches will be stored under the `sessionData`
directory. If you want to change this location, you have to override the
`sessionData` path before the `ready` event of the `app` module is emitted.
### `app.getVersion()`
Returns `string` - The version of the loaded application. If no version is found in the
application's `package.json` file, the version of the current bundle or
executable is returned.
### `app.getName()`
Returns `string` - The current application's name, which is the name in the application's
`package.json` file.
Usually the `name` field of `package.json` is a short lowercase name, according
to the npm modules spec. You should usually also specify a `productName`
field, which is your application's full capitalized name, and which will be
preferred over `name` by Electron.
### `app.setName(name)`
* `name` string
Overrides the current application's name.
**Note:** This function overrides the name used internally by Electron; it does not affect the name that the OS uses.
### `app.getLocale()`
Returns `string` - The current application locale, fetched using Chromium's `l10n_util` library.
Possible return values are documented [here](https://source.chromium.org/chromium/chromium/src/+/main:ui/base/l10n/l10n_util.cc).
To set the locale, you'll want to use a command line switch at app startup, which may be found [here](command-line-switches.md).
**Note:** When distributing your packaged app, you have to also ship the
`locales` folder.
**Note:** This API must be called after the `ready` event is emitted.
**Note:** To see example return values of this API compared to other locale and language APIs, see [`app.getPreferredSystemLanguages()`](#appgetpreferredsystemlanguages).
### `app.getLocaleCountryCode()`
Returns `string` - User operating system's locale two-letter [ISO 3166](https://www.iso.org/iso-3166-country-codes.html) country code. The value is taken from native OS APIs.
**Note:** When unable to detect locale country code, it returns empty string.
### `app.getSystemLocale()`
Returns `string` - The current system locale. On Windows and Linux, it is fetched using Chromium's `i18n` library. On macOS, `[NSLocale currentLocale]` is used instead. To get the user's current system language, which is not always the same as the locale, it is better to use [`app.getPreferredSystemLanguages()`](#appgetpreferredsystemlanguages).
Different operating systems also use the regional data differently:
* Windows 11 uses the regional format for numbers, dates, and times.
* macOS Monterey uses the region for formatting numbers, dates, times, and for selecting the currency symbol to use.
Therefore, this API can be used for purposes such as choosing a format for rendering dates and times in a calendar app, especially when the developer wants the format to be consistent with the OS.
**Note:** This API must be called after the `ready` event is emitted.
**Note:** To see example return values of this API compared to other locale and language APIs, see [`app.getPreferredSystemLanguages()`](#appgetpreferredsystemlanguages).
### `app.getPreferredSystemLanguages()`
Returns `string[]` - The user's preferred system languages from most preferred to least preferred, including the country codes if applicable. A user can modify and add to this list on Windows or macOS through the Language and Region settings.
The API uses `GlobalizationPreferences` (with a fallback to `GetSystemPreferredUILanguages`) on Windows, `\[NSLocale preferredLanguages\]` on macOS, and `g_get_language_names` on Linux.
This API can be used for purposes such as deciding what language to present the application in.
Here are some examples of return values of the various language and locale APIs with different configurations:
On Windows, given application locale is German, the regional format is Finnish (Finland), and the preferred system languages from most to least preferred are French (Canada), English (US), Simplified Chinese (China), Finnish, and Spanish (Latin America):
```js
app.getLocale() // 'de'
app.getSystemLocale() // 'fi-FI'
app.getPreferredSystemLanguages() // ['fr-CA', 'en-US', 'zh-Hans-CN', 'fi', 'es-419']
```
On macOS, given the application locale is German, the region is Finland, and the preferred system languages from most to least preferred are French (Canada), English (US), Simplified Chinese, and Spanish (Latin America):
```js
app.getLocale() // 'de'
app.getSystemLocale() // 'fr-FI'
app.getPreferredSystemLanguages() // ['fr-CA', 'en-US', 'zh-Hans-FI', 'es-419']
```
Both the available languages and regions and the possible return values differ between the two operating systems.
As can be seen with the example above, on Windows, it is possible that a preferred system language has no country code, and that one of the preferred system languages corresponds with the language used for the regional format. On macOS, the region serves more as a default country code: the user doesn't need to have Finnish as a preferred language to use Finland as the region,and the country code `FI` is used as the country code for preferred system languages that do not have associated countries in the language name.
### `app.addRecentDocument(path)` _macOS_ _Windows_
* `path` string
Adds `path` to the recent documents list.
This list is managed by the OS. On Windows, you can visit the list from the task
bar, and on macOS, you can visit it from dock menu.
### `app.clearRecentDocuments()` _macOS_ _Windows_
Clears the recent documents list.
### `app.setAsDefaultProtocolClient(protocol[, path, args])`
* `protocol` string - The name of your protocol, without `://`. For example,
if you want your app to handle `electron://` links, call this method with
`electron` as the parameter.
* `path` string (optional) _Windows_ - The path to the Electron executable.
Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Arguments passed to the executable.
Defaults to an empty array
Returns `boolean` - Whether the call succeeded.
Sets the current executable as the default handler for a protocol (aka URI
scheme). It allows you to integrate your app deeper into the operating system.
Once registered, all links with `your-protocol://` will be opened with the
current executable. The whole link, including protocol, will be passed to your
application as a parameter.
**Note:** On macOS, you can only register protocols that have been added to
your app's `info.plist`, which cannot be modified at runtime. However, you can
change the file during build time via [Electron Forge][electron-forge],
[Electron Packager][electron-packager], or by editing `info.plist` with a text
editor. Please refer to [Apple's documentation][CFBundleURLTypes] for details.
**Note:** In a Windows Store environment (when packaged as an `appx`) this API
will return `true` for all calls but the registry key it sets won't be accessible
by other applications. In order to register your Windows Store application
as a default protocol handler you must [declare the protocol in your manifest](https://learn.microsoft.com/en-us/uwp/schemas/appxpackage/uapmanifestschema/element-uap-protocol).
The API uses the Windows Registry and `LSSetDefaultHandlerForURLScheme` internally.
### `app.removeAsDefaultProtocolClient(protocol[, path, args])` _macOS_ _Windows_
* `protocol` string - The name of your protocol, without `://`.
* `path` string (optional) _Windows_ - Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Defaults to an empty array
Returns `boolean` - Whether the call succeeded.
This method checks if the current executable as the default handler for a
protocol (aka URI scheme). If so, it will remove the app as the default handler.
### `app.isDefaultProtocolClient(protocol[, path, args])`
* `protocol` string - The name of your protocol, without `://`.
* `path` string (optional) _Windows_ - Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Defaults to an empty array
Returns `boolean` - Whether the current executable is the default handler for a
protocol (aka URI scheme).
**Note:** On macOS, you can use this method to check if the app has been
registered as the default protocol handler for a protocol. You can also verify
this by checking `~/Library/Preferences/com.apple.LaunchServices.plist` on the
macOS machine. Please refer to
[Apple's documentation][LSCopyDefaultHandlerForURLScheme] for details.
The API uses the Windows Registry and `LSCopyDefaultHandlerForURLScheme` internally.
### `app.getApplicationNameForProtocol(url)`
* `url` string - a URL with the protocol name to check. Unlike the other
methods in this family, this accepts an entire URL, including `://` at a
minimum (e.g. `https://`).
Returns `string` - Name of the application handling the protocol, or an empty
string if there is no handler. For instance, if Electron is the default
handler of the URL, this could be `Electron` on Windows and Mac. However,
don't rely on the precise format which is not guaranteed to remain unchanged.
Expect a different format on Linux, possibly with a `.desktop` suffix.
This method returns the application name of the default handler for the protocol
(aka URI scheme) of a URL.
### `app.getApplicationInfoForProtocol(url)` _macOS_ _Windows_
* `url` string - a URL with the protocol name to check. Unlike the other
methods in this family, this accepts an entire URL, including `://` at a
minimum (e.g. `https://`).
Returns `Promise<Object>` - Resolve with an object containing the following:
* `icon` NativeImage - the display icon of the app handling the protocol.
* `path` string - installation path of the app handling the protocol.
* `name` string - display name of the app handling the protocol.
This method returns a promise that contains the application name, icon and path of the default handler for the protocol
(aka URI scheme) of a URL.
### `app.setUserTasks(tasks)` _Windows_
* `tasks` [Task[]](structures/task.md) - Array of `Task` objects
Adds `tasks` to the [Tasks][tasks] category of the Jump List on Windows.
`tasks` is an array of [`Task`](structures/task.md) objects.
Returns `boolean` - Whether the call succeeded.
**Note:** If you'd like to customize the Jump List even more use
`app.setJumpList(categories)` instead.
### `app.getJumpListSettings()` _Windows_
Returns `Object`:
* `minItems` Integer - The minimum number of items that will be shown in the
Jump List (for a more detailed description of this value see the
[MSDN docs][JumpListBeginListMSDN]).
* `removedItems` [JumpListItem[]](structures/jump-list-item.md) - Array of `JumpListItem`
objects that correspond to items that the user has explicitly removed from custom categories in the
Jump List. These items must not be re-added to the Jump List in the **next**
call to `app.setJumpList()`, Windows will not display any custom category
that contains any of the removed items.
### `app.setJumpList(categories)` _Windows_
* `categories` [JumpListCategory[]](structures/jump-list-category.md) | `null` - Array of `JumpListCategory` objects.
Returns `string`
Sets or removes a custom Jump List for the application, and returns one of the
following strings:
* `ok` - Nothing went wrong.
* `error` - One or more errors occurred, enable runtime logging to figure out
the likely cause.
* `invalidSeparatorError` - An attempt was made to add a separator to a
custom category in the Jump List. Separators are only allowed in the
standard `Tasks` category.
* `fileTypeRegistrationError` - An attempt was made to add a file link to
the Jump List for a file type the app isn't registered to handle.
* `customCategoryAccessDeniedError` - Custom categories can't be added to the
Jump List due to user privacy or group policy settings.
If `categories` is `null` the previously set custom Jump List (if any) will be
replaced by the standard Jump List for the app (managed by Windows).
**Note:** If a `JumpListCategory` object has neither the `type` nor the `name`
property set then its `type` is assumed to be `tasks`. If the `name` property
is set but the `type` property is omitted then the `type` is assumed to be
`custom`.
**Note:** Users can remove items from custom categories, and Windows will not
allow a removed item to be added back into a custom category until **after**
the next successful call to `app.setJumpList(categories)`. Any attempt to
re-add a removed item to a custom category earlier than that will result in the
entire custom category being omitted from the Jump List. The list of removed
items can be obtained using `app.getJumpListSettings()`.
**Note:** The maximum length of a Jump List item's `description` property is
260 characters. Beyond this limit, the item will not be added to the Jump
List, nor will it be displayed.
Here's a very simple example of creating a custom Jump List:
```js
const { app } = require('electron')
app.setJumpList([
{
type: 'custom',
name: 'Recent Projects',
items: [
{ type: 'file', path: 'C:\\Projects\\project1.proj' },
{ type: 'file', path: 'C:\\Projects\\project2.proj' }
]
},
{ // has a name so `type` is assumed to be "custom"
name: 'Tools',
items: [
{
type: 'task',
title: 'Tool A',
program: process.execPath,
args: '--run-tool-a',
iconPath: process.execPath,
iconIndex: 0,
description: 'Runs Tool A'
},
{
type: 'task',
title: 'Tool B',
program: process.execPath,
args: '--run-tool-b',
iconPath: process.execPath,
iconIndex: 0,
description: 'Runs Tool B'
}
]
},
{ type: 'frequent' },
{ // has no name and no type so `type` is assumed to be "tasks"
items: [
{
type: 'task',
title: 'New Project',
program: process.execPath,
args: '--new-project',
description: 'Create a new project.'
},
{ type: 'separator' },
{
type: 'task',
title: 'Recover Project',
program: process.execPath,
args: '--recover-project',
description: 'Recover Project'
}
]
}
])
```
### `app.requestSingleInstanceLock([additionalData])`
* `additionalData` Record<any, any> (optional) - A JSON object containing additional data to send to the first instance.
Returns `boolean`
The return value of this method indicates whether or not this instance of your
application successfully obtained the lock. If it failed to obtain the lock,
you can assume that another instance of your application is already running with
the lock and exit immediately.
I.e. This method returns `true` if your process is the primary instance of your
application and your app should continue loading. It returns `false` if your
process should immediately quit as it has sent its parameters to another
instance that has already acquired the lock.
On macOS, the system enforces single instance automatically when users try to open
a second instance of your app in Finder, and the `open-file` and `open-url`
events will be emitted for that. However when users start your app in command
line, the system's single instance mechanism will be bypassed, and you have to
use this method to ensure single instance.
An example of activating the window of primary instance when a second instance
starts:
```js
const { app, BrowserWindow } = require('electron')
let myWindow = null
const additionalData = { myKey: 'myValue' }
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {
app.on('second-instance', (event, commandLine, workingDirectory, additionalData) => {
// Print out data received from the second instance.
console.log(additionalData)
// Someone tried to run a second instance, we should focus our window.
if (myWindow) {
if (myWindow.isMinimized()) myWindow.restore()
myWindow.focus()
}
})
app.whenReady().then(() => {
myWindow = new BrowserWindow({})
myWindow.loadURL('https://electronjs.org')
})
}
```
### `app.hasSingleInstanceLock()`
Returns `boolean`
This method returns whether or not this instance of your app is currently
holding the single instance lock. You can request the lock with
`app.requestSingleInstanceLock()` and release with
`app.releaseSingleInstanceLock()`
### `app.releaseSingleInstanceLock()`
Releases all locks that were created by `requestSingleInstanceLock`. This will
allow multiple instances of the application to once again run side by side.
### `app.setUserActivity(type, userInfo[, webpageURL])` _macOS_
* `type` string - Uniquely identifies the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` any - App-specific state to store for use by another device.
* `webpageURL` string (optional) - The webpage to load in a browser if no suitable app is
installed on the resuming device. The scheme must be `http` or `https`.
Creates an `NSUserActivity` and sets it as the current activity. The activity
is eligible for [Handoff][handoff] to another device afterward.
### `app.getCurrentActivityType()` _macOS_
Returns `string` - The type of the currently running activity.
### `app.invalidateCurrentActivity()` _macOS_
Invalidates the current [Handoff][handoff] user activity.
### `app.resignCurrentActivity()` _macOS_
Marks the current [Handoff][handoff] user activity as inactive without invalidating it.
### `app.updateCurrentActivity(type, userInfo)` _macOS_
* `type` string - Uniquely identifies the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` any - App-specific state to store for use by another device.
Updates the current activity if its type matches `type`, merging the entries from
`userInfo` into its current `userInfo` dictionary.
### `app.setAppUserModelId(id)` _Windows_
* `id` string
Changes the [Application User Model ID][app-user-model-id] to `id`.
### `app.setActivationPolicy(policy)` _macOS_
* `policy` string - Can be 'regular', 'accessory', or 'prohibited'.
Sets the activation policy for a given app.
Activation policy types:
* 'regular' - The application is an ordinary app that appears in the Dock and may have a user interface.
* 'accessory' - The application doesnβt appear in the Dock and doesnβt have a menu bar, but it may be activated programmatically or by clicking on one of its windows.
* 'prohibited' - The application doesnβt appear in the Dock and may not create windows or be activated.
### `app.importCertificate(options, callback)` _Linux_
* `options` Object
* `certificate` string - Path for the pkcs12 file.
* `password` string - Passphrase for the certificate.
* `callback` Function
* `result` Integer - Result of import.
Imports the certificate in pkcs12 format into the platform certificate store.
`callback` is called with the `result` of import operation, a value of `0`
indicates success while any other value indicates failure according to Chromium [net_error_list](https://source.chromium.org/chromium/chromium/src/+/main:net/base/net_error_list.h).
### `app.configureHostResolver(options)`
* `options` Object
* `enableBuiltInResolver` boolean (optional) - Whether the built-in host
resolver is used in preference to getaddrinfo. When enabled, the built-in
resolver will attempt to use the system's DNS settings to do DNS lookups
itself. Enabled by default on macOS, disabled by default on Windows and
Linux.
* `secureDnsMode` string (optional) - Can be 'off', 'automatic' or 'secure'.
Configures the DNS-over-HTTP mode. When 'off', no DoH lookups will be
performed. When 'automatic', DoH lookups will be performed first if DoH is
available, and insecure DNS lookups will be performed as a fallback. When
'secure', only DoH lookups will be performed. Defaults to 'automatic'.
* `secureDnsServers` string[] (optional) - A list of DNS-over-HTTP
server templates. See [RFC8484 Β§ 3][] for details on the template format.
Most servers support the POST method; the template for such servers is
simply a URI. Note that for [some DNS providers][doh-providers], the
resolver will automatically upgrade to DoH unless DoH is explicitly
disabled, even if there are no DoH servers provided in this list.
* `enableAdditionalDnsQueryTypes` boolean (optional) - Controls whether additional DNS
query types, e.g. HTTPS (DNS type 65) will be allowed besides the
traditional A and AAAA queries when a request is being made via insecure
DNS. Has no effect on Secure DNS which always allows additional types.
Defaults to true.
Configures host resolution (DNS and DNS-over-HTTPS). By default, the following
resolvers will be used, in order:
1. DNS-over-HTTPS, if the [DNS provider supports it][doh-providers], then
2. the built-in resolver (enabled on macOS only by default), then
3. the system's resolver (e.g. `getaddrinfo`).
This can be configured to either restrict usage of non-encrypted DNS
(`secureDnsMode: "secure"`), or disable DNS-over-HTTPS (`secureDnsMode:
"off"`). It is also possible to enable or disable the built-in resolver.
To disable insecure DNS, you can specify a `secureDnsMode` of `"secure"`. If you do
so, you should make sure to provide a list of DNS-over-HTTPS servers to use, in
case the user's DNS configuration does not include a provider that supports
DoH.
```js
const { app } = require('electron')
app.whenReady().then(() => {
app.configureHostResolver({
secureDnsMode: 'secure',
secureDnsServers: [
'https://cloudflare-dns.com/dns-query'
]
})
})
```
This API must be called after the `ready` event is emitted.
[doh-providers]: https://source.chromium.org/chromium/chromium/src/+/main:net/dns/public/doh_provider_entry.cc;l=31?q=%22DohProviderEntry::GetList()%22&ss=chromium%2Fchromium%2Fsrc
[RFC8484 Β§ 3]: https://datatracker.ietf.org/doc/html/rfc8484#section-3
### `app.disableHardwareAcceleration()`
Disables hardware acceleration for current app.
This method can only be called before app is ready.
### `app.disableDomainBlockingFor3DAPIs()`
By default, Chromium disables 3D APIs (e.g. WebGL) until restart on a per
domain basis if the GPU processes crashes too frequently. This function
disables that behavior.
This method can only be called before app is ready.
### `app.getAppMetrics()`
Returns [`ProcessMetric[]`](structures/process-metric.md): Array of `ProcessMetric` objects that correspond to memory and CPU usage statistics of all the processes associated with the app.
### `app.getGPUFeatureStatus()`
Returns [`GPUFeatureStatus`](structures/gpu-feature-status.md) - The Graphics Feature Status from `chrome://gpu/`.
**Note:** This information is only usable after the `gpu-info-update` event is emitted.
### `app.getGPUInfo(infoType)`
* `infoType` string - Can be `basic` or `complete`.
Returns `Promise<unknown>`
For `infoType` equal to `complete`:
Promise is fulfilled with `Object` containing all the GPU Information as in [chromium's GPUInfo object](https://chromium.googlesource.com/chromium/src/+/4178e190e9da409b055e5dff469911ec6f6b716f/gpu/config/gpu_info.cc). This includes the version and driver information that's shown on `chrome://gpu` page.
For `infoType` equal to `basic`:
Promise is fulfilled with `Object` containing fewer attributes than when requested with `complete`. Here's an example of basic response:
```js
{
auxAttributes:
{
amdSwitchable: true,
canSupportThreadedTextureMailbox: false,
directComposition: false,
directRendering: true,
glResetNotificationStrategy: 0,
inProcessGpu: true,
initializationTime: 0,
jpegDecodeAcceleratorSupported: false,
optimus: false,
passthroughCmdDecoder: false,
sandboxed: false,
softwareRendering: false,
supportsOverlays: false,
videoDecodeAcceleratorFlags: 0
},
gpuDevice:
[{ active: true, deviceId: 26657, vendorId: 4098 },
{ active: false, deviceId: 3366, vendorId: 32902 }],
machineModelName: 'MacBookPro',
machineModelVersion: '11.5'
}
```
Using `basic` should be preferred if only basic information like `vendorId` or `deviceId` is needed.
### `app.setBadgeCount([count])` _Linux_ _macOS_
* `count` Integer (optional) - If a value is provided, set the badge to the provided value otherwise, on macOS, display a plain white dot (e.g. unknown number of notifications). On Linux, if a value is not provided the badge will not display.
Returns `boolean` - Whether the call succeeded.
Sets the counter badge for current app. Setting the count to `0` will hide the
badge.
On macOS, it shows on the dock icon. On Linux, it only works for Unity launcher.
**Note:** Unity launcher requires a `.desktop` file to work. For more information,
please read the [Unity integration documentation][unity-requirement].
**Note:** On macOS, you need to ensure that your application has the permission
to display notifications for this method to work.
### `app.getBadgeCount()` _Linux_ _macOS_
Returns `Integer` - The current value displayed in the counter badge.
### `app.isUnityRunning()` _Linux_
Returns `boolean` - Whether the current desktop environment is Unity launcher.
### `app.getLoginItemSettings([options])` _macOS_ _Windows_
* `options` Object (optional)
* `path` string (optional) _Windows_ - The executable path to compare against.
Defaults to `process.execPath`.
* `args` string[] (optional) _Windows_ - The command-line arguments to compare
against. Defaults to an empty array.
If you provided `path` and `args` options to `app.setLoginItemSettings`, then you
need to pass the same arguments here for `openAtLogin` to be set correctly.
Returns `Object`:
* `openAtLogin` boolean - `true` if the app is set to open at login.
* `openAsHidden` boolean _macOS_ - `true` if the app is set to open as hidden at login.
This setting is not available on [MAS builds][mas-builds].
* `wasOpenedAtLogin` boolean _macOS_ - `true` if the app was opened at login
automatically. This setting is not available on [MAS builds][mas-builds].
* `wasOpenedAsHidden` boolean _macOS_ - `true` if the app was opened as a hidden login
item. This indicates that the app should not open any windows at startup.
This setting is not available on [MAS builds][mas-builds].
* `restoreState` boolean _macOS_ - `true` if the app was opened as a login item that
should restore the state from the previous session. This indicates that the
app should restore the windows that were open the last time the app was
closed. This setting is not available on [MAS builds][mas-builds].
* `executableWillLaunchAtLogin` boolean _Windows_ - `true` if app is set to open at login and its run key is not deactivated. This differs from `openAtLogin` as it ignores the `args` option, this property will be true if the given executable would be launched at login with **any** arguments.
* `launchItems` Object[] _Windows_
* `name` string _Windows_ - name value of a registry entry.
* `path` string _Windows_ - The executable to an app that corresponds to a registry entry.
* `args` string[] _Windows_ - the command-line arguments to pass to the executable.
* `scope` string _Windows_ - one of `user` or `machine`. Indicates whether the registry entry is under `HKEY_CURRENT USER` or `HKEY_LOCAL_MACHINE`.
* `enabled` boolean _Windows_ - `true` if the app registry key is startup approved and therefore shows as `enabled` in Task Manager and Windows settings.
### `app.setLoginItemSettings(settings)` _macOS_ _Windows_
* `settings` Object
* `openAtLogin` boolean (optional) - `true` to open the app at login, `false` to remove
the app as a login item. Defaults to `false`.
* `openAsHidden` boolean (optional) _macOS_ - `true` to open the app as hidden. Defaults to
`false`. The user can edit this setting from the System Preferences so
`app.getLoginItemSettings().wasOpenedAsHidden` should be checked when the app
is opened to know the current value. This setting is not available on [MAS builds][mas-builds].
* `path` string (optional) _Windows_ - The executable to launch at login.
Defaults to `process.execPath`.
* `args` string[] (optional) _Windows_ - The command-line arguments to pass to
the executable. Defaults to an empty array. Take care to wrap paths in
quotes.
* `enabled` boolean (optional) _Windows_ - `true` will change the startup approved registry key and `enable / disable` the App in Task Manager and Windows Settings.
Defaults to `true`.
* `name` string (optional) _Windows_ - value name to write into registry. Defaults to the app's AppUserModelId().
Set the app's login item settings.
To work with Electron's `autoUpdater` on Windows, which uses [Squirrel][Squirrel-Windows],
you'll want to set the launch path to Update.exe, and pass arguments that specify your
application name. For example:
``` js
const { app } = require('electron')
const path = require('node:path')
const appFolder = path.dirname(process.execPath)
const updateExe = path.resolve(appFolder, '..', 'Update.exe')
const exeName = path.basename(process.execPath)
app.setLoginItemSettings({
openAtLogin: true,
path: updateExe,
args: [
'--processStart', `"${exeName}"`,
'--process-start-args', '"--hidden"'
]
})
```
### `app.isAccessibilitySupportEnabled()` _macOS_ _Windows_
Returns `boolean` - `true` if Chrome's accessibility support is enabled,
`false` otherwise. This API will return `true` if the use of assistive
technologies, such as screen readers, has been detected. See
https://www.chromium.org/developers/design-documents/accessibility for more
details.
### `app.setAccessibilitySupportEnabled(enabled)` _macOS_ _Windows_
* `enabled` boolean - Enable or disable [accessibility tree](https://developers.google.com/web/fundamentals/accessibility/semantics-builtin/the-accessibility-tree) rendering
Manually enables Chrome's accessibility support, allowing to expose accessibility switch to users in application settings. See [Chromium's accessibility docs](https://www.chromium.org/developers/design-documents/accessibility) for more
details. Disabled by default.
This API must be called after the `ready` event is emitted.
**Note:** Rendering accessibility tree can significantly affect the performance of your app. It should not be enabled by default.
### `app.showAboutPanel()`
Show the app's about panel options. These options can be overridden with `app.setAboutPanelOptions(options)`. This function runs asynchronously.
### `app.setAboutPanelOptions(options)`
* `options` Object
* `applicationName` string (optional) - The app's name.
* `applicationVersion` string (optional) - The app's version.
* `copyright` string (optional) - Copyright information.
* `version` string (optional) _macOS_ - The app's build version number.
* `credits` string (optional) _macOS_ _Windows_ - Credit information.
* `authors` string[] (optional) _Linux_ - List of app authors.
* `website` string (optional) _Linux_ - The app's website.
* `iconPath` string (optional) _Linux_ _Windows_ - Path to the app's icon in a JPEG or PNG file format. On Linux, will be shown as 64x64 pixels while retaining aspect ratio.
Set the about panel options. This will override the values defined in the app's `.plist` file on macOS. See the [Apple docs][about-panel-options] for more details. On Linux, values must be set in order to be shown; there are no defaults.
If you do not set `credits` but still wish to surface them in your app, AppKit will look for a file named "Credits.html", "Credits.rtf", and "Credits.rtfd", in that order, in the bundle returned by the NSBundle class method main. The first file found is used, and if none is found, the info area is left blank. See Apple [documentation](https://developer.apple.com/documentation/appkit/nsaboutpaneloptioncredits?language=objc) for more information.
### `app.isEmojiPanelSupported()`
Returns `boolean` - whether or not the current OS version allows for native emoji pickers.
### `app.showEmojiPanel()` _macOS_ _Windows_
Show the platform's native emoji picker.
### `app.startAccessingSecurityScopedResource(bookmarkData)` _mas_
* `bookmarkData` string - The base64 encoded security scoped bookmark data returned by the `dialog.showOpenDialog` or `dialog.showSaveDialog` methods.
Returns `Function` - This function **must** be called once you have finished accessing the security scoped file. If you do not remember to stop accessing the bookmark, [kernel resources will be leaked](https://developer.apple.com/reference/foundation/nsurl/1417051-startaccessingsecurityscopedreso?language=objc) and your app will lose its ability to reach outside the sandbox completely, until your app is restarted.
```js
const { app, dialog } = require('electron')
const fs = require('node:fs')
let filepath
let bookmark
dialog.showOpenDialog(null, { securityScopedBookmarks: true }).then(({ filePaths, bookmarks }) => {
filepath = filePaths[0]
bookmark = bookmarks[0]
fs.readFileSync(filepath)
})
// ... restart app ...
const stopAccessingSecurityScopedResource = app.startAccessingSecurityScopedResource(bookmark)
fs.readFileSync(filepath)
stopAccessingSecurityScopedResource()
```
Start accessing a security scoped resource. With this method Electron applications that are packaged for the Mac App Store may reach outside their sandbox to access files chosen by the user. See [Apple's documentation](https://developer.apple.com/library/content/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW16) for a description of how this system works.
### `app.enableSandbox()`
Enables full sandbox mode on the app. This means that all renderers will be launched sandboxed, regardless of the value of the `sandbox` flag in [`WebPreferences`](structures/web-preferences.md).
This method can only be called before app is ready.
### `app.isInApplicationsFolder()` _macOS_
Returns `boolean` - Whether the application is currently running from the
systems Application folder. Use in combination with `app.moveToApplicationsFolder()`
### `app.moveToApplicationsFolder([options])` _macOS_
* `options` Object (optional)
* `conflictHandler` Function\<boolean> (optional) - A handler for potential conflict in move failure.
* `conflictType` string - The type of move conflict encountered by the handler; can be `exists` or `existsAndRunning`, where `exists` means that an app of the same name is present in the Applications directory and `existsAndRunning` means both that it exists and that it's presently running.
Returns `boolean` - Whether the move was successful. Please note that if
the move is successful, your application will quit and relaunch.
No confirmation dialog will be presented by default. If you wish to allow
the user to confirm the operation, you may do so using the
[`dialog`](dialog.md) API.
**NOTE:** This method throws errors if anything other than the user causes the
move to fail. For instance if the user cancels the authorization dialog, this
method returns false. If we fail to perform the copy, then this method will
throw an error. The message in the error should be informative and tell
you exactly what went wrong.
By default, if an app of the same name as the one being moved exists in the Applications directory and is _not_ running, the existing app will be trashed and the active app moved into its place. If it _is_ running, the preexisting running app will assume focus and the previously active app will quit itself. This behavior can be changed by providing the optional conflict handler, where the boolean returned by the handler determines whether or not the move conflict is resolved with default behavior. i.e. returning `false` will ensure no further action is taken, returning `true` will result in the default behavior and the method continuing.
For example:
```js
const { app, dialog } = require('electron')
app.moveToApplicationsFolder({
conflictHandler: (conflictType) => {
if (conflictType === 'exists') {
return dialog.showMessageBoxSync({
type: 'question',
buttons: ['Halt Move', 'Continue Move'],
defaultId: 0,
message: 'An app of this name already exists'
}) === 1
}
}
})
```
Would mean that if an app already exists in the user directory, if the user chooses to 'Continue Move' then the function would continue with its default behavior and the existing app will be trashed and the active app moved into its place.
### `app.isSecureKeyboardEntryEnabled()` _macOS_
Returns `boolean` - whether `Secure Keyboard Entry` is enabled.
By default this API will return `false`.
### `app.setSecureKeyboardEntryEnabled(enabled)` _macOS_
* `enabled` boolean - Enable or disable `Secure Keyboard Entry`
Set the `Secure Keyboard Entry` is enabled in your application.
By using this API, important information such as password and other sensitive information can be prevented from being intercepted by other processes.
See [Apple's documentation](https://developer.apple.com/library/archive/technotes/tn2150/_index.html) for more
details.
**Note:** Enable `Secure Keyboard Entry` only when it is needed and disable it when it is no longer needed.
## Properties
### `app.accessibilitySupportEnabled` _macOS_ _Windows_
A `boolean` property that's `true` if Chrome's accessibility support is enabled, `false` otherwise. This property will be `true` if the use of assistive technologies, such as screen readers, has been detected. Setting this property to `true` manually enables Chrome's accessibility support, allowing developers to expose accessibility switch to users in application settings.
See [Chromium's accessibility docs](https://www.chromium.org/developers/design-documents/accessibility) for more details. Disabled by default.
This API must be called after the `ready` event is emitted.
**Note:** Rendering accessibility tree can significantly affect the performance of your app. It should not be enabled by default.
### `app.applicationMenu`
A `Menu | null` property that returns [`Menu`](menu.md) if one has been set and `null` otherwise.
Users can pass a [Menu](menu.md) to set this property.
### `app.badgeCount` _Linux_ _macOS_
An `Integer` property that returns the badge count for current app. Setting the count to `0` will hide the badge.
On macOS, setting this with any nonzero integer shows on the dock icon. On Linux, this property only works for Unity launcher.
**Note:** Unity launcher requires a `.desktop` file to work. For more information,
please read the [Unity integration documentation][unity-requirement].
**Note:** On macOS, you need to ensure that your application has the permission
to display notifications for this property to take effect.
### `app.commandLine` _Readonly_
A [`CommandLine`](./command-line.md) object that allows you to read and manipulate the
command line arguments that Chromium uses.
### `app.dock` _macOS_ _Readonly_
A [`Dock`](./dock.md) `| undefined` object that allows you to perform actions on your app icon in the user's
dock on macOS.
### `app.isPackaged` _Readonly_
A `boolean` property that returns `true` if the app is packaged, `false` otherwise. For many apps, this property can be used to distinguish development and production environments.

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

### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.

### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

[Bug]: Open at login with setLoginItemSettings in MAS build is not working
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.
<img width="477" alt="image" src="https://user-images.githubusercontent.com/17458685/224576455-a9145dfc-7121-4097-9fe4-a472f0c2ead4.png">
### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

[Bug]: Open at login with setLoginItemSettings in MAS build is not working
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.

### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.

### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.
<img width="477" alt="image" src="https://user-images.githubusercontent.com/17458685/224576455-a9145dfc-7121-4097-9fe4-a472f0c2ead4.png">
### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

# app
> Control your application's event lifecycle.
Process: [Main](../glossary.md#main-process)
The following example shows how to quit the application when the last window is
closed:
```js
const { app } = require('electron')
app.on('window-all-closed', () => {
app.quit()
})
```
## Events
The `app` object emits the following events:
### Event: 'will-finish-launching'
Emitted when the application has finished basic startup. On Windows and Linux,
the `will-finish-launching` event is the same as the `ready` event; on macOS,
this event represents the `applicationWillFinishLaunching` notification of
`NSApplication`.
In most cases, you should do everything in the `ready` event handler.
### Event: 'ready'
Returns:
* `event` Event
* `launchInfo` Record<string, any> | [NotificationResponse](structures/notification-response.md) _macOS_
Emitted once, when Electron has finished initializing. On macOS, `launchInfo`
holds the `userInfo` of the [`NSUserNotification`](https://developer.apple.com/documentation/foundation/nsusernotification)
or information from [`UNNotificationResponse`](https://developer.apple.com/documentation/usernotifications/unnotificationresponse)
that was used to open the application, if it was launched from Notification Center.
You can also call `app.isReady()` to check if this event has already fired and `app.whenReady()`
to get a Promise that is fulfilled when Electron is initialized.
### Event: 'window-all-closed'
Emitted when all windows have been closed.
If you do not subscribe to this event and all windows are closed, the default
behavior is to quit the app; however, if you subscribe, you control whether the
app quits or not. If the user pressed `Cmd + Q`, or the developer called
`app.quit()`, Electron will first try to close all the windows and then emit the
`will-quit` event, and in this case the `window-all-closed` event would not be
emitted.
### Event: 'before-quit'
Returns:
* `event` Event
Emitted before the application starts closing its windows.
Calling `event.preventDefault()` will prevent the default behavior, which is
terminating the application.
**Note:** If application quit was initiated by `autoUpdater.quitAndInstall()`,
then `before-quit` is emitted _after_ emitting `close` event on all windows and
closing them.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'will-quit'
Returns:
* `event` Event
Emitted when all windows have been closed and the application will quit.
Calling `event.preventDefault()` will prevent the default behavior, which is
terminating the application.
See the description of the `window-all-closed` event for the differences between
the `will-quit` and `window-all-closed` events.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'quit'
Returns:
* `event` Event
* `exitCode` Integer
Emitted when the application is quitting.
**Note:** On Windows, this event will not be emitted if the app is closed due
to a shutdown/restart of the system or a user logout.
### Event: 'open-file' _macOS_
Returns:
* `event` Event
* `path` string
Emitted when the user wants to open a file with the application. The `open-file`
event is usually emitted when the application is already open and the OS wants
to reuse the application to open the file. `open-file` is also emitted when a
file is dropped onto the dock and the application is not yet running. Make sure
to listen for the `open-file` event very early in your application startup to
handle this case (even before the `ready` event is emitted).
You should call `event.preventDefault()` if you want to handle this event.
On Windows, you have to parse `process.argv` (in the main process) to get the
filepath.
### Event: 'open-url' _macOS_
Returns:
* `event` Event
* `url` string
Emitted when the user wants to open a URL with the application. Your application's
`Info.plist` file must define the URL scheme within the `CFBundleURLTypes` key, and
set `NSPrincipalClass` to `AtomApplication`.
As with the `open-file` event, be sure to register a listener for the `open-url`
event early in your application startup to detect if the application is being opened to handle a URL.
If you register the listener in response to a `ready` event, you'll miss URLs that trigger the launch of your application.
### Event: 'activate' _macOS_
Returns:
* `event` Event
* `hasVisibleWindows` boolean
Emitted when the application is activated. Various actions can trigger
this event, such as launching the application for the first time, attempting
to re-launch the application when it's already running, or clicking on the
application's dock or taskbar icon.
### Event: 'did-become-active' _macOS_
Returns:
* `event` Event
Emitted when the application becomes active. This differs from the `activate` event in
that `did-become-active` is emitted every time the app becomes active, not only
when Dock icon is clicked or application is re-launched. It is also emitted when a user
switches to the app via the macOS App Switcher.
### Event: 'did-resign-active' _macOS_
Returns:
* `event` Event
Emitted when the app is no longer active and doesnβt have focus. This can be triggered,
for example, by clicking on another application or by using the macOS App Switcher to
switch to another application.
### Event: 'continue-activity' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity on
another device.
* `details` Object
* `webpageURL` string (optional) - A string identifying the URL of the webpage accessed by the activity on another device, if available.
Emitted during [Handoff][handoff] when an activity from a different device wants
to be resumed. You should call `event.preventDefault()` if you want to handle
this event.
A user activity can be continued only in an app that has the same developer Team
ID as the activity's source app and that supports the activity's type.
Supported activity types are specified in the app's `Info.plist` under the
`NSUserActivityTypes` key.
### Event: 'will-continue-activity' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
Emitted during [Handoff][handoff] before an activity from a different device wants
to be resumed. You should call `event.preventDefault()` if you want to handle
this event.
### Event: 'continue-activity-error' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `error` string - A string with the error's localized description.
Emitted during [Handoff][handoff] when an activity from a different device
fails to be resumed.
### Event: 'activity-was-continued' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity.
Emitted during [Handoff][handoff] after an activity from this device was successfully
resumed on another one.
### Event: 'update-activity-state' _macOS_
Returns:
* `event` Event
* `type` string - A string identifying the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` unknown - Contains app-specific state stored by the activity.
Emitted when [Handoff][handoff] is about to be resumed on another device. If you need to update the state to be transferred, you should call `event.preventDefault()` immediately, construct a new `userInfo` dictionary and call `app.updateCurrentActivity()` in a timely manner. Otherwise, the operation will fail and `continue-activity-error` will be called.
### Event: 'new-window-for-tab' _macOS_
Returns:
* `event` Event
Emitted when the user clicks the native macOS new tab button. The new
tab button is only visible if the current `BrowserWindow` has a
`tabbingIdentifier`
### Event: 'browser-window-blur'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a [browserWindow](browser-window.md) gets blurred.
### Event: 'browser-window-focus'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a [browserWindow](browser-window.md) gets focused.
### Event: 'browser-window-created'
Returns:
* `event` Event
* `window` [BrowserWindow](browser-window.md)
Emitted when a new [browserWindow](browser-window.md) is created.
### Event: 'web-contents-created'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
Emitted when a new [webContents](web-contents.md) is created.
### Event: 'certificate-error'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `url` string
* `error` string - The error code
* `certificate` [Certificate](structures/certificate.md)
* `callback` Function
* `isTrusted` boolean - Whether to consider the certificate as trusted
* `isMainFrame` boolean
Emitted when failed to verify the `certificate` for `url`, to trust the
certificate you should prevent the default behavior with
`event.preventDefault()` and call `callback(true)`.
```js
const { app } = require('electron')
app.on('certificate-error', (event, webContents, url, error, certificate, callback) => {
if (url === 'https://github.com') {
// Verification logic.
event.preventDefault()
callback(true)
} else {
callback(false)
}
})
```
### Event: 'select-client-certificate'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `url` URL
* `certificateList` [Certificate[]](structures/certificate.md)
* `callback` Function
* `certificate` [Certificate](structures/certificate.md) (optional)
Emitted when a client certificate is requested.
The `url` corresponds to the navigation entry requesting the client certificate
and `callback` can be called with an entry filtered from the list. Using
`event.preventDefault()` prevents the application from using the first
certificate from the store.
```js
const { app } = require('electron')
app.on('select-client-certificate', (event, webContents, url, list, callback) => {
event.preventDefault()
callback(list[0])
})
```
### Event: 'login'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `authenticationResponseDetails` Object
* `url` URL
* `authInfo` Object
* `isProxy` boolean
* `scheme` string
* `host` string
* `port` Integer
* `realm` string
* `callback` Function
* `username` string (optional)
* `password` string (optional)
Emitted when `webContents` wants to do basic auth.
The default behavior is to cancel all authentications. To override this you
should prevent the default behavior with `event.preventDefault()` and call
`callback(username, password)` with the credentials.
```js
const { app } = require('electron')
app.on('login', (event, webContents, details, authInfo, callback) => {
event.preventDefault()
callback('username', 'secret')
})
```
If `callback` is called without a username or password, the authentication
request will be cancelled and the authentication error will be returned to the
page.
### Event: 'gpu-info-update'
Emitted whenever there is a GPU info update.
### Event: 'gpu-process-crashed' _Deprecated_
Returns:
* `event` Event
* `killed` boolean
Emitted when the GPU process crashes or is killed.
**Deprecated:** This event is superceded by the `child-process-gone` event
which contains more information about why the child process disappeared. It
isn't always because it crashed. The `killed` boolean can be replaced by
checking `reason === 'killed'` when you switch to that event.
### Event: 'renderer-process-crashed' _Deprecated_
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `killed` boolean
Emitted when the renderer process of `webContents` crashes or is killed.
**Deprecated:** This event is superceded by the `render-process-gone` event
which contains more information about why the render process disappeared. It
isn't always because it crashed. The `killed` boolean can be replaced by
checking `reason === 'killed'` when you switch to that event.
### Event: 'render-process-gone'
Returns:
* `event` Event
* `webContents` [WebContents](web-contents.md)
* `details` [RenderProcessGoneDetails](structures/render-process-gone-details.md)
Emitted when the renderer process unexpectedly disappears. This is normally
because it was crashed or killed.
### Event: 'child-process-gone'
Returns:
* `event` Event
* `details` Object
* `type` string - Process type. One of the following values:
* `Utility`
* `Zygote`
* `Sandbox helper`
* `GPU`
* `Pepper Plugin`
* `Pepper Plugin Broker`
* `Unknown`
* `reason` string - The reason the child process is gone. Possible values:
* `clean-exit` - Process exited with an exit code of zero
* `abnormal-exit` - Process exited with a non-zero exit code
* `killed` - Process was sent a SIGTERM or otherwise killed externally
* `crashed` - Process crashed
* `oom` - Process ran out of memory
* `launch-failed` - Process never successfully launched
* `integrity-failure` - Windows code integrity checks failed
* `exitCode` number - The exit code for the process
(e.g. status from waitpid if on posix, from GetExitCodeProcess on Windows).
* `serviceName` string (optional) - The non-localized name of the process.
* `name` string (optional) - The name of the process.
Examples for utility: `Audio Service`, `Content Decryption Module Service`, `Network Service`, `Video Capture`, etc.
Emitted when the child process unexpectedly disappears. This is normally
because it was crashed or killed. It does not include renderer processes.
### Event: 'accessibility-support-changed' _macOS_ _Windows_
Returns:
* `event` Event
* `accessibilitySupportEnabled` boolean - `true` when Chrome's accessibility
support is enabled, `false` otherwise.
Emitted when Chrome's accessibility support changes. This event fires when
assistive technologies, such as screen readers, are enabled or disabled.
See https://www.chromium.org/developers/design-documents/accessibility for more
details.
### Event: 'session-created'
Returns:
* `session` [Session](session.md)
Emitted when Electron has created a new `session`.
```js
const { app } = require('electron')
app.on('session-created', (session) => {
console.log(session)
})
```
### Event: 'second-instance'
Returns:
* `event` Event
* `argv` string[] - An array of the second instance's command line arguments
* `workingDirectory` string - The second instance's working directory
* `additionalData` unknown - A JSON object of additional data passed from the second instance
This event will be emitted inside the primary instance of your application
when a second instance has been executed and calls `app.requestSingleInstanceLock()`.
`argv` is an Array of the second instance's command line arguments,
and `workingDirectory` is its current working directory. Usually
applications respond to this by making their primary window focused and
non-minimized.
**Note:** `argv` will not be exactly the same list of arguments as those passed
to the second instance. The order might change and additional arguments might be appended.
If you need to maintain the exact same arguments, it's advised to use `additionalData` instead.
**Note:** If the second instance is started by a different user than the first, the `argv` array will not include the arguments.
This event is guaranteed to be emitted after the `ready` event of `app`
gets emitted.
**Note:** Extra command line arguments might be added by Chromium,
such as `--original-process-start-time`.
## Methods
The `app` object has the following methods:
**Note:** Some methods are only available on specific operating systems and are
labeled as such.
### `app.quit()`
Try to close all windows. The `before-quit` event will be emitted first. If all
windows are successfully closed, the `will-quit` event will be emitted and by
default the application will terminate.
This method guarantees that all `beforeunload` and `unload` event handlers are
correctly executed. It is possible that a window cancels the quitting by
returning `false` in the `beforeunload` event handler.
### `app.exit([exitCode])`
* `exitCode` Integer (optional)
Exits immediately with `exitCode`. `exitCode` defaults to 0.
All windows will be closed immediately without asking the user, and the `before-quit`
and `will-quit` events will not be emitted.
### `app.relaunch([options])`
* `options` Object (optional)
* `args` string[] (optional)
* `execPath` string (optional)
Relaunches the app when current instance exits.
By default, the new instance will use the same working directory and command line
arguments with current instance. When `args` is specified, the `args` will be
passed as command line arguments instead. When `execPath` is specified, the
`execPath` will be executed for relaunch instead of current app.
Note that this method does not quit the app when executed, you have to call
`app.quit` or `app.exit` after calling `app.relaunch` to make the app restart.
When `app.relaunch` is called for multiple times, multiple instances will be
started after current instance exited.
An example of restarting current instance immediately and adding a new command
line argument to the new instance:
```js
const { app } = require('electron')
app.relaunch({ args: process.argv.slice(1).concat(['--relaunch']) })
app.exit(0)
```
### `app.isReady()`
Returns `boolean` - `true` if Electron has finished initializing, `false` otherwise.
See also `app.whenReady()`.
### `app.whenReady()`
Returns `Promise<void>` - fulfilled when Electron is initialized.
May be used as a convenient alternative to checking `app.isReady()`
and subscribing to the `ready` event if the app is not ready yet.
### `app.focus([options])`
* `options` Object (optional)
* `steal` boolean _macOS_ - Make the receiver the active app even if another app is
currently active.
On Linux, focuses on the first visible window. On macOS, makes the application
the active app. On Windows, focuses on the application's first window.
You should seek to use the `steal` option as sparingly as possible.
### `app.hide()` _macOS_
Hides all application windows without minimizing them.
### `app.isHidden()` _macOS_
Returns `boolean` - `true` if the applicationβincluding all of its windowsβis hidden (e.g. with `Command-H`), `false` otherwise.
### `app.show()` _macOS_
Shows application windows after they were hidden. Does not automatically focus
them.
### `app.setAppLogsPath([path])`
* `path` string (optional) - A custom path for your logs. Must be absolute.
Sets or creates a directory your app's logs which can then be manipulated with `app.getPath()` or `app.setPath(pathName, newPath)`.
Calling `app.setAppLogsPath()` without a `path` parameter will result in this directory being set to `~/Library/Logs/YourAppName` on _macOS_, and inside the `userData` directory on _Linux_ and _Windows_.
### `app.getAppPath()`
Returns `string` - The current application directory.
### `app.getPath(name)`
* `name` string - You can request the following paths by the name:
* `home` User's home directory.
* `appData` Per-user application data directory, which by default points to:
* `%APPDATA%` on Windows
* `$XDG_CONFIG_HOME` or `~/.config` on Linux
* `~/Library/Application Support` on macOS
* `userData` The directory for storing your app's configuration files, which
by default is the `appData` directory appended with your app's name. By
convention files storing user data should be written to this directory, and
it is not recommended to write large files here because some environments
may backup this directory to cloud storage.
* `sessionData` The directory for storing data generated by `Session`, such
as localStorage, cookies, disk cache, downloaded dictionaries, network
state, devtools files. By default this points to `userData`. Chromium may
write very large disk cache here, so if your app does not rely on browser
storage like localStorage or cookies to save user data, it is recommended
to set this directory to other locations to avoid polluting the `userData`
directory.
* `temp` Temporary directory.
* `exe` The current executable file.
* `module` The `libchromiumcontent` library.
* `desktop` The current user's Desktop directory.
* `documents` Directory for a user's "My Documents".
* `downloads` Directory for a user's downloads.
* `music` Directory for a user's music.
* `pictures` Directory for a user's pictures.
* `videos` Directory for a user's videos.
* `recent` Directory for the user's recent files (Windows only).
* `logs` Directory for your app's log folder.
* `crashDumps` Directory where crash dumps are stored.
Returns `string` - A path to a special directory or file associated with `name`. On
failure, an `Error` is thrown.
If `app.getPath('logs')` is called without called `app.setAppLogsPath()` being called first, a default log directory will be created equivalent to calling `app.setAppLogsPath()` without a `path` parameter.
### `app.getFileIcon(path[, options])`
* `path` string
* `options` Object (optional)
* `size` string
* `small` - 16x16
* `normal` - 32x32
* `large` - 48x48 on _Linux_, 32x32 on _Windows_, unsupported on _macOS_.
Returns `Promise<NativeImage>` - fulfilled with the app's icon, which is a [NativeImage](native-image.md).
Fetches a path's associated icon.
On _Windows_, there a 2 kinds of icons:
* Icons associated with certain file extensions, like `.mp3`, `.png`, etc.
* Icons inside the file itself, like `.exe`, `.dll`, `.ico`.
On _Linux_ and _macOS_, icons depend on the application associated with file mime type.
### `app.setPath(name, path)`
* `name` string
* `path` string
Overrides the `path` to a special directory or file associated with `name`.
If the path specifies a directory that does not exist, an `Error` is thrown.
In that case, the directory should be created with `fs.mkdirSync` or similar.
You can only override paths of a `name` defined in `app.getPath`.
By default, web pages' cookies and caches will be stored under the `sessionData`
directory. If you want to change this location, you have to override the
`sessionData` path before the `ready` event of the `app` module is emitted.
### `app.getVersion()`
Returns `string` - The version of the loaded application. If no version is found in the
application's `package.json` file, the version of the current bundle or
executable is returned.
### `app.getName()`
Returns `string` - The current application's name, which is the name in the application's
`package.json` file.
Usually the `name` field of `package.json` is a short lowercase name, according
to the npm modules spec. You should usually also specify a `productName`
field, which is your application's full capitalized name, and which will be
preferred over `name` by Electron.
### `app.setName(name)`
* `name` string
Overrides the current application's name.
**Note:** This function overrides the name used internally by Electron; it does not affect the name that the OS uses.
### `app.getLocale()`
Returns `string` - The current application locale, fetched using Chromium's `l10n_util` library.
Possible return values are documented [here](https://source.chromium.org/chromium/chromium/src/+/main:ui/base/l10n/l10n_util.cc).
To set the locale, you'll want to use a command line switch at app startup, which may be found [here](command-line-switches.md).
**Note:** When distributing your packaged app, you have to also ship the
`locales` folder.
**Note:** This API must be called after the `ready` event is emitted.
**Note:** To see example return values of this API compared to other locale and language APIs, see [`app.getPreferredSystemLanguages()`](#appgetpreferredsystemlanguages).
### `app.getLocaleCountryCode()`
Returns `string` - User operating system's locale two-letter [ISO 3166](https://www.iso.org/iso-3166-country-codes.html) country code. The value is taken from native OS APIs.
**Note:** When unable to detect locale country code, it returns empty string.
### `app.getSystemLocale()`
Returns `string` - The current system locale. On Windows and Linux, it is fetched using Chromium's `i18n` library. On macOS, `[NSLocale currentLocale]` is used instead. To get the user's current system language, which is not always the same as the locale, it is better to use [`app.getPreferredSystemLanguages()`](#appgetpreferredsystemlanguages).
Different operating systems also use the regional data differently:
* Windows 11 uses the regional format for numbers, dates, and times.
* macOS Monterey uses the region for formatting numbers, dates, times, and for selecting the currency symbol to use.
Therefore, this API can be used for purposes such as choosing a format for rendering dates and times in a calendar app, especially when the developer wants the format to be consistent with the OS.
**Note:** This API must be called after the `ready` event is emitted.
**Note:** To see example return values of this API compared to other locale and language APIs, see [`app.getPreferredSystemLanguages()`](#appgetpreferredsystemlanguages).
### `app.getPreferredSystemLanguages()`
Returns `string[]` - The user's preferred system languages from most preferred to least preferred, including the country codes if applicable. A user can modify and add to this list on Windows or macOS through the Language and Region settings.
The API uses `GlobalizationPreferences` (with a fallback to `GetSystemPreferredUILanguages`) on Windows, `\[NSLocale preferredLanguages\]` on macOS, and `g_get_language_names` on Linux.
This API can be used for purposes such as deciding what language to present the application in.
Here are some examples of return values of the various language and locale APIs with different configurations:
On Windows, given application locale is German, the regional format is Finnish (Finland), and the preferred system languages from most to least preferred are French (Canada), English (US), Simplified Chinese (China), Finnish, and Spanish (Latin America):
```js
app.getLocale() // 'de'
app.getSystemLocale() // 'fi-FI'
app.getPreferredSystemLanguages() // ['fr-CA', 'en-US', 'zh-Hans-CN', 'fi', 'es-419']
```
On macOS, given the application locale is German, the region is Finland, and the preferred system languages from most to least preferred are French (Canada), English (US), Simplified Chinese, and Spanish (Latin America):
```js
app.getLocale() // 'de'
app.getSystemLocale() // 'fr-FI'
app.getPreferredSystemLanguages() // ['fr-CA', 'en-US', 'zh-Hans-FI', 'es-419']
```
Both the available languages and regions and the possible return values differ between the two operating systems.
As can be seen with the example above, on Windows, it is possible that a preferred system language has no country code, and that one of the preferred system languages corresponds with the language used for the regional format. On macOS, the region serves more as a default country code: the user doesn't need to have Finnish as a preferred language to use Finland as the region,and the country code `FI` is used as the country code for preferred system languages that do not have associated countries in the language name.
### `app.addRecentDocument(path)` _macOS_ _Windows_
* `path` string
Adds `path` to the recent documents list.
This list is managed by the OS. On Windows, you can visit the list from the task
bar, and on macOS, you can visit it from dock menu.
### `app.clearRecentDocuments()` _macOS_ _Windows_
Clears the recent documents list.
### `app.setAsDefaultProtocolClient(protocol[, path, args])`
* `protocol` string - The name of your protocol, without `://`. For example,
if you want your app to handle `electron://` links, call this method with
`electron` as the parameter.
* `path` string (optional) _Windows_ - The path to the Electron executable.
Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Arguments passed to the executable.
Defaults to an empty array
Returns `boolean` - Whether the call succeeded.
Sets the current executable as the default handler for a protocol (aka URI
scheme). It allows you to integrate your app deeper into the operating system.
Once registered, all links with `your-protocol://` will be opened with the
current executable. The whole link, including protocol, will be passed to your
application as a parameter.
**Note:** On macOS, you can only register protocols that have been added to
your app's `info.plist`, which cannot be modified at runtime. However, you can
change the file during build time via [Electron Forge][electron-forge],
[Electron Packager][electron-packager], or by editing `info.plist` with a text
editor. Please refer to [Apple's documentation][CFBundleURLTypes] for details.
**Note:** In a Windows Store environment (when packaged as an `appx`) this API
will return `true` for all calls but the registry key it sets won't be accessible
by other applications. In order to register your Windows Store application
as a default protocol handler you must [declare the protocol in your manifest](https://learn.microsoft.com/en-us/uwp/schemas/appxpackage/uapmanifestschema/element-uap-protocol).
The API uses the Windows Registry and `LSSetDefaultHandlerForURLScheme` internally.
### `app.removeAsDefaultProtocolClient(protocol[, path, args])` _macOS_ _Windows_
* `protocol` string - The name of your protocol, without `://`.
* `path` string (optional) _Windows_ - Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Defaults to an empty array
Returns `boolean` - Whether the call succeeded.
This method checks if the current executable as the default handler for a
protocol (aka URI scheme). If so, it will remove the app as the default handler.
### `app.isDefaultProtocolClient(protocol[, path, args])`
* `protocol` string - The name of your protocol, without `://`.
* `path` string (optional) _Windows_ - Defaults to `process.execPath`
* `args` string[] (optional) _Windows_ - Defaults to an empty array
Returns `boolean` - Whether the current executable is the default handler for a
protocol (aka URI scheme).
**Note:** On macOS, you can use this method to check if the app has been
registered as the default protocol handler for a protocol. You can also verify
this by checking `~/Library/Preferences/com.apple.LaunchServices.plist` on the
macOS machine. Please refer to
[Apple's documentation][LSCopyDefaultHandlerForURLScheme] for details.
The API uses the Windows Registry and `LSCopyDefaultHandlerForURLScheme` internally.
### `app.getApplicationNameForProtocol(url)`
* `url` string - a URL with the protocol name to check. Unlike the other
methods in this family, this accepts an entire URL, including `://` at a
minimum (e.g. `https://`).
Returns `string` - Name of the application handling the protocol, or an empty
string if there is no handler. For instance, if Electron is the default
handler of the URL, this could be `Electron` on Windows and Mac. However,
don't rely on the precise format which is not guaranteed to remain unchanged.
Expect a different format on Linux, possibly with a `.desktop` suffix.
This method returns the application name of the default handler for the protocol
(aka URI scheme) of a URL.
### `app.getApplicationInfoForProtocol(url)` _macOS_ _Windows_
* `url` string - a URL with the protocol name to check. Unlike the other
methods in this family, this accepts an entire URL, including `://` at a
minimum (e.g. `https://`).
Returns `Promise<Object>` - Resolve with an object containing the following:
* `icon` NativeImage - the display icon of the app handling the protocol.
* `path` string - installation path of the app handling the protocol.
* `name` string - display name of the app handling the protocol.
This method returns a promise that contains the application name, icon and path of the default handler for the protocol
(aka URI scheme) of a URL.
### `app.setUserTasks(tasks)` _Windows_
* `tasks` [Task[]](structures/task.md) - Array of `Task` objects
Adds `tasks` to the [Tasks][tasks] category of the Jump List on Windows.
`tasks` is an array of [`Task`](structures/task.md) objects.
Returns `boolean` - Whether the call succeeded.
**Note:** If you'd like to customize the Jump List even more use
`app.setJumpList(categories)` instead.
### `app.getJumpListSettings()` _Windows_
Returns `Object`:
* `minItems` Integer - The minimum number of items that will be shown in the
Jump List (for a more detailed description of this value see the
[MSDN docs][JumpListBeginListMSDN]).
* `removedItems` [JumpListItem[]](structures/jump-list-item.md) - Array of `JumpListItem`
objects that correspond to items that the user has explicitly removed from custom categories in the
Jump List. These items must not be re-added to the Jump List in the **next**
call to `app.setJumpList()`, Windows will not display any custom category
that contains any of the removed items.
### `app.setJumpList(categories)` _Windows_
* `categories` [JumpListCategory[]](structures/jump-list-category.md) | `null` - Array of `JumpListCategory` objects.
Returns `string`
Sets or removes a custom Jump List for the application, and returns one of the
following strings:
* `ok` - Nothing went wrong.
* `error` - One or more errors occurred, enable runtime logging to figure out
the likely cause.
* `invalidSeparatorError` - An attempt was made to add a separator to a
custom category in the Jump List. Separators are only allowed in the
standard `Tasks` category.
* `fileTypeRegistrationError` - An attempt was made to add a file link to
the Jump List for a file type the app isn't registered to handle.
* `customCategoryAccessDeniedError` - Custom categories can't be added to the
Jump List due to user privacy or group policy settings.
If `categories` is `null` the previously set custom Jump List (if any) will be
replaced by the standard Jump List for the app (managed by Windows).
**Note:** If a `JumpListCategory` object has neither the `type` nor the `name`
property set then its `type` is assumed to be `tasks`. If the `name` property
is set but the `type` property is omitted then the `type` is assumed to be
`custom`.
**Note:** Users can remove items from custom categories, and Windows will not
allow a removed item to be added back into a custom category until **after**
the next successful call to `app.setJumpList(categories)`. Any attempt to
re-add a removed item to a custom category earlier than that will result in the
entire custom category being omitted from the Jump List. The list of removed
items can be obtained using `app.getJumpListSettings()`.
**Note:** The maximum length of a Jump List item's `description` property is
260 characters. Beyond this limit, the item will not be added to the Jump
List, nor will it be displayed.
Here's a very simple example of creating a custom Jump List:
```js
const { app } = require('electron')
app.setJumpList([
{
type: 'custom',
name: 'Recent Projects',
items: [
{ type: 'file', path: 'C:\\Projects\\project1.proj' },
{ type: 'file', path: 'C:\\Projects\\project2.proj' }
]
},
{ // has a name so `type` is assumed to be "custom"
name: 'Tools',
items: [
{
type: 'task',
title: 'Tool A',
program: process.execPath,
args: '--run-tool-a',
iconPath: process.execPath,
iconIndex: 0,
description: 'Runs Tool A'
},
{
type: 'task',
title: 'Tool B',
program: process.execPath,
args: '--run-tool-b',
iconPath: process.execPath,
iconIndex: 0,
description: 'Runs Tool B'
}
]
},
{ type: 'frequent' },
{ // has no name and no type so `type` is assumed to be "tasks"
items: [
{
type: 'task',
title: 'New Project',
program: process.execPath,
args: '--new-project',
description: 'Create a new project.'
},
{ type: 'separator' },
{
type: 'task',
title: 'Recover Project',
program: process.execPath,
args: '--recover-project',
description: 'Recover Project'
}
]
}
])
```
### `app.requestSingleInstanceLock([additionalData])`
* `additionalData` Record<any, any> (optional) - A JSON object containing additional data to send to the first instance.
Returns `boolean`
The return value of this method indicates whether or not this instance of your
application successfully obtained the lock. If it failed to obtain the lock,
you can assume that another instance of your application is already running with
the lock and exit immediately.
I.e. This method returns `true` if your process is the primary instance of your
application and your app should continue loading. It returns `false` if your
process should immediately quit as it has sent its parameters to another
instance that has already acquired the lock.
On macOS, the system enforces single instance automatically when users try to open
a second instance of your app in Finder, and the `open-file` and `open-url`
events will be emitted for that. However when users start your app in command
line, the system's single instance mechanism will be bypassed, and you have to
use this method to ensure single instance.
An example of activating the window of primary instance when a second instance
starts:
```js
const { app, BrowserWindow } = require('electron')
let myWindow = null
const additionalData = { myKey: 'myValue' }
const gotTheLock = app.requestSingleInstanceLock(additionalData)
if (!gotTheLock) {
app.quit()
} else {
app.on('second-instance', (event, commandLine, workingDirectory, additionalData) => {
// Print out data received from the second instance.
console.log(additionalData)
// Someone tried to run a second instance, we should focus our window.
if (myWindow) {
if (myWindow.isMinimized()) myWindow.restore()
myWindow.focus()
}
})
app.whenReady().then(() => {
myWindow = new BrowserWindow({})
myWindow.loadURL('https://electronjs.org')
})
}
```
### `app.hasSingleInstanceLock()`
Returns `boolean`
This method returns whether or not this instance of your app is currently
holding the single instance lock. You can request the lock with
`app.requestSingleInstanceLock()` and release with
`app.releaseSingleInstanceLock()`
### `app.releaseSingleInstanceLock()`
Releases all locks that were created by `requestSingleInstanceLock`. This will
allow multiple instances of the application to once again run side by side.
### `app.setUserActivity(type, userInfo[, webpageURL])` _macOS_
* `type` string - Uniquely identifies the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` any - App-specific state to store for use by another device.
* `webpageURL` string (optional) - The webpage to load in a browser if no suitable app is
installed on the resuming device. The scheme must be `http` or `https`.
Creates an `NSUserActivity` and sets it as the current activity. The activity
is eligible for [Handoff][handoff] to another device afterward.
### `app.getCurrentActivityType()` _macOS_
Returns `string` - The type of the currently running activity.
### `app.invalidateCurrentActivity()` _macOS_
Invalidates the current [Handoff][handoff] user activity.
### `app.resignCurrentActivity()` _macOS_
Marks the current [Handoff][handoff] user activity as inactive without invalidating it.
### `app.updateCurrentActivity(type, userInfo)` _macOS_
* `type` string - Uniquely identifies the activity. Maps to
[`NSUserActivity.activityType`][activity-type].
* `userInfo` any - App-specific state to store for use by another device.
Updates the current activity if its type matches `type`, merging the entries from
`userInfo` into its current `userInfo` dictionary.
### `app.setAppUserModelId(id)` _Windows_
* `id` string
Changes the [Application User Model ID][app-user-model-id] to `id`.
### `app.setActivationPolicy(policy)` _macOS_
* `policy` string - Can be 'regular', 'accessory', or 'prohibited'.
Sets the activation policy for a given app.
Activation policy types:
* 'regular' - The application is an ordinary app that appears in the Dock and may have a user interface.
* 'accessory' - The application doesnβt appear in the Dock and doesnβt have a menu bar, but it may be activated programmatically or by clicking on one of its windows.
* 'prohibited' - The application doesnβt appear in the Dock and may not create windows or be activated.
### `app.importCertificate(options, callback)` _Linux_
* `options` Object
* `certificate` string - Path for the pkcs12 file.
* `password` string - Passphrase for the certificate.
* `callback` Function
* `result` Integer - Result of import.
Imports the certificate in pkcs12 format into the platform certificate store.
`callback` is called with the `result` of import operation, a value of `0`
indicates success while any other value indicates failure according to Chromium [net_error_list](https://source.chromium.org/chromium/chromium/src/+/main:net/base/net_error_list.h).
### `app.configureHostResolver(options)`
* `options` Object
* `enableBuiltInResolver` boolean (optional) - Whether the built-in host
resolver is used in preference to getaddrinfo. When enabled, the built-in
resolver will attempt to use the system's DNS settings to do DNS lookups
itself. Enabled by default on macOS, disabled by default on Windows and
Linux.
* `secureDnsMode` string (optional) - Can be 'off', 'automatic' or 'secure'.
Configures the DNS-over-HTTP mode. When 'off', no DoH lookups will be
performed. When 'automatic', DoH lookups will be performed first if DoH is
available, and insecure DNS lookups will be performed as a fallback. When
'secure', only DoH lookups will be performed. Defaults to 'automatic'.
* `secureDnsServers` string[] (optional) - A list of DNS-over-HTTP
server templates. See [RFC8484 Β§ 3][] for details on the template format.
Most servers support the POST method; the template for such servers is
simply a URI. Note that for [some DNS providers][doh-providers], the
resolver will automatically upgrade to DoH unless DoH is explicitly
disabled, even if there are no DoH servers provided in this list.
* `enableAdditionalDnsQueryTypes` boolean (optional) - Controls whether additional DNS
query types, e.g. HTTPS (DNS type 65) will be allowed besides the
traditional A and AAAA queries when a request is being made via insecure
DNS. Has no effect on Secure DNS which always allows additional types.
Defaults to true.
Configures host resolution (DNS and DNS-over-HTTPS). By default, the following
resolvers will be used, in order:
1. DNS-over-HTTPS, if the [DNS provider supports it][doh-providers], then
2. the built-in resolver (enabled on macOS only by default), then
3. the system's resolver (e.g. `getaddrinfo`).
This can be configured to either restrict usage of non-encrypted DNS
(`secureDnsMode: "secure"`), or disable DNS-over-HTTPS (`secureDnsMode:
"off"`). It is also possible to enable or disable the built-in resolver.
To disable insecure DNS, you can specify a `secureDnsMode` of `"secure"`. If you do
so, you should make sure to provide a list of DNS-over-HTTPS servers to use, in
case the user's DNS configuration does not include a provider that supports
DoH.
```js
const { app } = require('electron')
app.whenReady().then(() => {
app.configureHostResolver({
secureDnsMode: 'secure',
secureDnsServers: [
'https://cloudflare-dns.com/dns-query'
]
})
})
```
This API must be called after the `ready` event is emitted.
[doh-providers]: https://source.chromium.org/chromium/chromium/src/+/main:net/dns/public/doh_provider_entry.cc;l=31?q=%22DohProviderEntry::GetList()%22&ss=chromium%2Fchromium%2Fsrc
[RFC8484 Β§ 3]: https://datatracker.ietf.org/doc/html/rfc8484#section-3
### `app.disableHardwareAcceleration()`
Disables hardware acceleration for current app.
This method can only be called before app is ready.
### `app.disableDomainBlockingFor3DAPIs()`
By default, Chromium disables 3D APIs (e.g. WebGL) until restart on a per
domain basis if the GPU processes crashes too frequently. This function
disables that behavior.
This method can only be called before app is ready.
### `app.getAppMetrics()`
Returns [`ProcessMetric[]`](structures/process-metric.md): Array of `ProcessMetric` objects that correspond to memory and CPU usage statistics of all the processes associated with the app.
### `app.getGPUFeatureStatus()`
Returns [`GPUFeatureStatus`](structures/gpu-feature-status.md) - The Graphics Feature Status from `chrome://gpu/`.
**Note:** This information is only usable after the `gpu-info-update` event is emitted.
### `app.getGPUInfo(infoType)`
* `infoType` string - Can be `basic` or `complete`.
Returns `Promise<unknown>`
For `infoType` equal to `complete`:
Promise is fulfilled with `Object` containing all the GPU Information as in [chromium's GPUInfo object](https://chromium.googlesource.com/chromium/src/+/4178e190e9da409b055e5dff469911ec6f6b716f/gpu/config/gpu_info.cc). This includes the version and driver information that's shown on `chrome://gpu` page.
For `infoType` equal to `basic`:
Promise is fulfilled with `Object` containing fewer attributes than when requested with `complete`. Here's an example of basic response:
```js
{
auxAttributes:
{
amdSwitchable: true,
canSupportThreadedTextureMailbox: false,
directComposition: false,
directRendering: true,
glResetNotificationStrategy: 0,
inProcessGpu: true,
initializationTime: 0,
jpegDecodeAcceleratorSupported: false,
optimus: false,
passthroughCmdDecoder: false,
sandboxed: false,
softwareRendering: false,
supportsOverlays: false,
videoDecodeAcceleratorFlags: 0
},
gpuDevice:
[{ active: true, deviceId: 26657, vendorId: 4098 },
{ active: false, deviceId: 3366, vendorId: 32902 }],
machineModelName: 'MacBookPro',
machineModelVersion: '11.5'
}
```
Using `basic` should be preferred if only basic information like `vendorId` or `deviceId` is needed.
### `app.setBadgeCount([count])` _Linux_ _macOS_
* `count` Integer (optional) - If a value is provided, set the badge to the provided value otherwise, on macOS, display a plain white dot (e.g. unknown number of notifications). On Linux, if a value is not provided the badge will not display.
Returns `boolean` - Whether the call succeeded.
Sets the counter badge for current app. Setting the count to `0` will hide the
badge.
On macOS, it shows on the dock icon. On Linux, it only works for Unity launcher.
**Note:** Unity launcher requires a `.desktop` file to work. For more information,
please read the [Unity integration documentation][unity-requirement].
**Note:** On macOS, you need to ensure that your application has the permission
to display notifications for this method to work.
### `app.getBadgeCount()` _Linux_ _macOS_
Returns `Integer` - The current value displayed in the counter badge.
### `app.isUnityRunning()` _Linux_
Returns `boolean` - Whether the current desktop environment is Unity launcher.
### `app.getLoginItemSettings([options])` _macOS_ _Windows_
* `options` Object (optional)
* `path` string (optional) _Windows_ - The executable path to compare against.
Defaults to `process.execPath`.
* `args` string[] (optional) _Windows_ - The command-line arguments to compare
against. Defaults to an empty array.
If you provided `path` and `args` options to `app.setLoginItemSettings`, then you
need to pass the same arguments here for `openAtLogin` to be set correctly.
Returns `Object`:
* `openAtLogin` boolean - `true` if the app is set to open at login.
* `openAsHidden` boolean _macOS_ - `true` if the app is set to open as hidden at login.
This setting is not available on [MAS builds][mas-builds].
* `wasOpenedAtLogin` boolean _macOS_ - `true` if the app was opened at login
automatically. This setting is not available on [MAS builds][mas-builds].
* `wasOpenedAsHidden` boolean _macOS_ - `true` if the app was opened as a hidden login
item. This indicates that the app should not open any windows at startup.
This setting is not available on [MAS builds][mas-builds].
* `restoreState` boolean _macOS_ - `true` if the app was opened as a login item that
should restore the state from the previous session. This indicates that the
app should restore the windows that were open the last time the app was
closed. This setting is not available on [MAS builds][mas-builds].
* `executableWillLaunchAtLogin` boolean _Windows_ - `true` if app is set to open at login and its run key is not deactivated. This differs from `openAtLogin` as it ignores the `args` option, this property will be true if the given executable would be launched at login with **any** arguments.
* `launchItems` Object[] _Windows_
* `name` string _Windows_ - name value of a registry entry.
* `path` string _Windows_ - The executable to an app that corresponds to a registry entry.
* `args` string[] _Windows_ - the command-line arguments to pass to the executable.
* `scope` string _Windows_ - one of `user` or `machine`. Indicates whether the registry entry is under `HKEY_CURRENT USER` or `HKEY_LOCAL_MACHINE`.
* `enabled` boolean _Windows_ - `true` if the app registry key is startup approved and therefore shows as `enabled` in Task Manager and Windows settings.
### `app.setLoginItemSettings(settings)` _macOS_ _Windows_
* `settings` Object
* `openAtLogin` boolean (optional) - `true` to open the app at login, `false` to remove
the app as a login item. Defaults to `false`.
* `openAsHidden` boolean (optional) _macOS_ - `true` to open the app as hidden. Defaults to
`false`. The user can edit this setting from the System Preferences so
`app.getLoginItemSettings().wasOpenedAsHidden` should be checked when the app
is opened to know the current value. This setting is not available on [MAS builds][mas-builds].
* `path` string (optional) _Windows_ - The executable to launch at login.
Defaults to `process.execPath`.
* `args` string[] (optional) _Windows_ - The command-line arguments to pass to
the executable. Defaults to an empty array. Take care to wrap paths in
quotes.
* `enabled` boolean (optional) _Windows_ - `true` will change the startup approved registry key and `enable / disable` the App in Task Manager and Windows Settings.
Defaults to `true`.
* `name` string (optional) _Windows_ - value name to write into registry. Defaults to the app's AppUserModelId().
Set the app's login item settings.
To work with Electron's `autoUpdater` on Windows, which uses [Squirrel][Squirrel-Windows],
you'll want to set the launch path to Update.exe, and pass arguments that specify your
application name. For example:
``` js
const { app } = require('electron')
const path = require('node:path')
const appFolder = path.dirname(process.execPath)
const updateExe = path.resolve(appFolder, '..', 'Update.exe')
const exeName = path.basename(process.execPath)
app.setLoginItemSettings({
openAtLogin: true,
path: updateExe,
args: [
'--processStart', `"${exeName}"`,
'--process-start-args', '"--hidden"'
]
})
```
### `app.isAccessibilitySupportEnabled()` _macOS_ _Windows_
Returns `boolean` - `true` if Chrome's accessibility support is enabled,
`false` otherwise. This API will return `true` if the use of assistive
technologies, such as screen readers, has been detected. See

details.
### `app.setAccessibilitySupportEnabled(enabled)` _macOS_ _Windows_
* `enabled` boolean - Enable or disable [accessibility tree](https://developers.google.com/web/fundamentals/accessibility/semantics-builtin/the-accessibility-tree) rendering
Manually enables Chrome's accessibility support, allowing to expose accessibility switch to users in application settings. See [Chromium's accessibility docs](https://www.chromium.org/developers/design-documents/accessibility) for more
details. Disabled by default.
This API must be called after the `ready` event is emitted.
**Note:** Rendering accessibility tree can significantly affect the performance of your app. It should not be enabled by default.
### `app.showAboutPanel()`
Show the app's about panel options. These options can be overridden with `app.setAboutPanelOptions(options)`. This function runs asynchronously.
### `app.setAboutPanelOptions(options)`
* `options` Object
* `applicationName` string (optional) - The app's name.
* `applicationVersion` string (optional) - The app's version.
* `copyright` string (optional) - Copyright information.
* `version` string (optional) _macOS_ - The app's build version number.
* `credits` string (optional) _macOS_ _Windows_ - Credit information.
* `authors` string[] (optional) _Linux_ - List of app authors.
* `website` string (optional) _Linux_ - The app's website.
* `iconPath` string (optional) _Linux_ _Windows_ - Path to the app's icon in a JPEG or PNG file format. On Linux, will be shown as 64x64 pixels while retaining aspect ratio.
Set the about panel options. This will override the values defined in the app's `.plist` file on macOS. See the [Apple docs][about-panel-options] for more details. On Linux, values must be set in order to be shown; there are no defaults.
If you do not set `credits` but still wish to surface them in your app, AppKit will look for a file named "Credits.html", "Credits.rtf", and "Credits.rtfd", in that order, in the bundle returned by the NSBundle class method main. The first file found is used, and if none is found, the info area is left blank. See Apple [documentation](https://developer.apple.com/documentation/appkit/nsaboutpaneloptioncredits?language=objc) for more information.
### `app.isEmojiPanelSupported()`
Returns `boolean` - whether or not the current OS version allows for native emoji pickers.
### `app.showEmojiPanel()` _macOS_ _Windows_
Show the platform's native emoji picker.
### `app.startAccessingSecurityScopedResource(bookmarkData)` _mas_
* `bookmarkData` string - The base64 encoded security scoped bookmark data returned by the `dialog.showOpenDialog` or `dialog.showSaveDialog` methods.
Returns `Function` - This function **must** be called once you have finished accessing the security scoped file. If you do not remember to stop accessing the bookmark, [kernel resources will be leaked](https://developer.apple.com/reference/foundation/nsurl/1417051-startaccessingsecurityscopedreso?language=objc) and your app will lose its ability to reach outside the sandbox completely, until your app is restarted.
```js
const { app, dialog } = require('electron')
const fs = require('node:fs')
let filepath
let bookmark
dialog.showOpenDialog(null, { securityScopedBookmarks: true }).then(({ filePaths, bookmarks }) => {
filepath = filePaths[0]
bookmark = bookmarks[0]
fs.readFileSync(filepath)
})
// ... restart app ...
const stopAccessingSecurityScopedResource = app.startAccessingSecurityScopedResource(bookmark)
fs.readFileSync(filepath)
stopAccessingSecurityScopedResource()
```
Start accessing a security scoped resource. With this method Electron applications that are packaged for the Mac App Store may reach outside their sandbox to access files chosen by the user. See [Apple's documentation](https://developer.apple.com/library/content/documentation/Security/Conceptual/AppSandboxDesignGuide/AppSandboxInDepth/AppSandboxInDepth.html#//apple_ref/doc/uid/TP40011183-CH3-SW16) for a description of how this system works.
### `app.enableSandbox()`
Enables full sandbox mode on the app. This means that all renderers will be launched sandboxed, regardless of the value of the `sandbox` flag in [`WebPreferences`](structures/web-preferences.md).
This method can only be called before app is ready.
### `app.isInApplicationsFolder()` _macOS_
Returns `boolean` - Whether the application is currently running from the
systems Application folder. Use in combination with `app.moveToApplicationsFolder()`
### `app.moveToApplicationsFolder([options])` _macOS_
* `options` Object (optional)
* `conflictHandler` Function\<boolean> (optional) - A handler for potential conflict in move failure.
* `conflictType` string - The type of move conflict encountered by the handler; can be `exists` or `existsAndRunning`, where `exists` means that an app of the same name is present in the Applications directory and `existsAndRunning` means both that it exists and that it's presently running.
Returns `boolean` - Whether the move was successful. Please note that if
the move is successful, your application will quit and relaunch.
No confirmation dialog will be presented by default. If you wish to allow
the user to confirm the operation, you may do so using the
[`dialog`](dialog.md) API.
**NOTE:** This method throws errors if anything other than the user causes the
move to fail. For instance if the user cancels the authorization dialog, this
method returns false. If we fail to perform the copy, then this method will
throw an error. The message in the error should be informative and tell
you exactly what went wrong.
By default, if an app of the same name as the one being moved exists in the Applications directory and is _not_ running, the existing app will be trashed and the active app moved into its place. If it _is_ running, the preexisting running app will assume focus and the previously active app will quit itself. This behavior can be changed by providing the optional conflict handler, where the boolean returned by the handler determines whether or not the move conflict is resolved with default behavior. i.e. returning `false` will ensure no further action is taken, returning `true` will result in the default behavior and the method continuing.
For example:
```js
const { app, dialog } = require('electron')
app.moveToApplicationsFolder({
conflictHandler: (conflictType) => {
if (conflictType === 'exists') {
return dialog.showMessageBoxSync({
type: 'question',
buttons: ['Halt Move', 'Continue Move'],
defaultId: 0,
message: 'An app of this name already exists'
}) === 1
}
}
})
```
Would mean that if an app already exists in the user directory, if the user chooses to 'Continue Move' then the function would continue with its default behavior and the existing app will be trashed and the active app moved into its place.
### `app.isSecureKeyboardEntryEnabled()` _macOS_
Returns `boolean` - whether `Secure Keyboard Entry` is enabled.
By default this API will return `false`.
### `app.setSecureKeyboardEntryEnabled(enabled)` _macOS_
* `enabled` boolean - Enable or disable `Secure Keyboard Entry`
Set the `Secure Keyboard Entry` is enabled in your application.
By using this API, important information such as password and other sensitive information can be prevented from being intercepted by other processes.
See [Apple's documentation](https://developer.apple.com/library/archive/technotes/tn2150/_index.html) for more
details.
**Note:** Enable `Secure Keyboard Entry` only when it is needed and disable it when it is no longer needed.
## Properties
### `app.accessibilitySupportEnabled` _macOS_ _Windows_
A `boolean` property that's `true` if Chrome's accessibility support is enabled, `false` otherwise. This property will be `true` if the use of assistive technologies, such as screen readers, has been detected. Setting this property to `true` manually enables Chrome's accessibility support, allowing developers to expose accessibility switch to users in application settings.
See [Chromium's accessibility docs](https://www.chromium.org/developers/design-documents/accessibility) for more details. Disabled by default.
This API must be called after the `ready` event is emitted.
**Note:** Rendering accessibility tree can significantly affect the performance of your app. It should not be enabled by default.
### `app.applicationMenu`
A `Menu | null` property that returns [`Menu`](menu.md) if one has been set and `null` otherwise.
Users can pass a [Menu](menu.md) to set this property.
### `app.badgeCount` _Linux_ _macOS_
An `Integer` property that returns the badge count for current app. Setting the count to `0` will hide the badge.
On macOS, setting this with any nonzero integer shows on the dock icon. On Linux, this property only works for Unity launcher.
**Note:** Unity launcher requires a `.desktop` file to work. For more information,
please read the [Unity integration documentation][unity-requirement].
**Note:** On macOS, you need to ensure that your application has the permission
to display notifications for this property to take effect.
### `app.commandLine` _Readonly_
A [`CommandLine`](./command-line.md) object that allows you to read and manipulate the
command line arguments that Chromium uses.
### `app.dock` _macOS_ _Readonly_
A [`Dock`](./dock.md) `| undefined` object that allows you to perform actions on your app icon in the user's
dock on macOS.
### `app.isPackaged` _Readonly_
A `boolean` property that returns `true` if the app is packaged, `false` otherwise. For many apps, this property can be used to distinguish development and production environments.

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

|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.
<img width="477" alt="image" src="https://user-images.githubusercontent.com/17458685/224576455-a9145dfc-7121-4097-9fe4-a472f0c2ead4.png">
### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

[Bug]: Open at login with setLoginItemSettings in MAS build is not working
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.
<img width="477" alt="image" src="https://user-images.githubusercontent.com/17458685/224576455-a9145dfc-7121-4097-9fe4-a472f0c2ead4.png">
### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

[Bug]: Open at login with setLoginItemSettings in MAS build is not working
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.
<img width="477" alt="image" src="https://user-images.githubusercontent.com/17458685/224576455-a9145dfc-7121-4097-9fe4-a472f0c2ead4.png">
### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

### Electron Version
16.0.6
### What operating system are you using?
macOS
### Operating System Version
Version 13.2 (22D49)
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Setting app to open at login with setLoginItemSettings api should work both locally and with MAS build.
Locally the app is added to login items but when i build it for MAS this doesn't work.
### Actual Behavior
Setting app to open at login with setLoginItemSettings api works locally but doesn't work in MAS build.
In MAS build the app is not added to login items.

### Testcase Gist URL
_No response_
### Additional Information
According to docs https://www.electronjs.org/docs/latest/api/app#appsetloginitemsettingssettings-macos-windows setting login item in MAS build should work by using the following API
```js
app.setLoginItemSettings({
openAtLogin: openAtLogin,
})
```
In the docs on limitations of MAS build there is no mention of any limitation of using above API https://www.electronjs.org/docs/latest/tutorial/mac-app-store-submission-guide#limitations-of-mas-build

[Bug]: Electron 28 breaks `import` of transitive dependencies inside ES modules
|
### Preflight Checklist

- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
28.0.0-alpha.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
27.0.0
### Expected Behavior
Importing an ESM dependency which imports some other dependency (ESM or CJS) should work from inside `app.asar`
### Actual Behavior
The module lookup starts at ```node_modules/<directory where the dependency's `main` file lives>/node_modules```, doesn't find the transitive dependency there and then crashes, never reaching the top-level `node_modules` which is where the transitive dependency actually lives:
### Testcase Gist URL
_No response_
### Additional Information
I've run into this using [this repro](https://github.com/electron/asar/issues/249#issuecomment-1434998313), where the ESM dependency `got` is imported causing the app to crash when looking for the transitive ESM dependency `@sindresorhus/is`. I've put together a minimal reproduction with two local dependencies, which should make it easier to test different variables: https://github.com/erikian/esm-asar-demo
Note that this problem seems to be limited to dependencies inside `node_modules`, i.e. ESM imports across project files work fine:
```ts
// src/main.mjs
import printStuff from './printStuff.js'
printStuff('it works!')
// src/printStuff.js
import logger from './logger.js'
export default function printStuff(...stuff) {
logger(...stuff)
}
// src/logger.js
export default function logger(...args) {
console.log(...args)
}
```
Some findings:
- `const { default: printStuff } = await import('my-esm-dependency')` doesn't work out of the box, but it does work when setting `process.noAsar = true` before importing. Moving the import into the `app.whenReady` callback also doesn't work
- `import printStuff from 'my-esm-dependency'` doesn't work at all, not even with `process.noAsar = true`
- This is not limited to ESM entrypoints. I also get the same errors on the `commonjs-entrypoint` branch, and changing to Electron 27.0.0 fixes the problem.

[Bug]: Electron 28 breaks `import` of transitive dependencies inside ES modules
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
28.0.0-alpha.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
27.0.0
### Expected Behavior
Importing an ESM dependency which imports some other dependency (ESM or CJS) should work from inside `app.asar`
### Actual Behavior
The module lookup starts at ```node_modules/<directory where the dependency's `main` file lives>/node_modules```, doesn't find the transitive dependency there and then crashes, never reaching the top-level `node_modules` which is where the transitive dependency actually lives:
### Testcase Gist URL
_No response_
### Additional Information
I've run into this using [this repro](https://github.com/electron/asar/issues/249#issuecomment-1434998313), where the ESM dependency `got` is imported causing the app to crash when looking for the transitive ESM dependency `@sindresorhus/is`. I've put together a minimal reproduction with two local dependencies, which should make it easier to test different variables: https://github.com/erikian/esm-asar-demo
Note that this problem seems to be limited to dependencies inside `node_modules`, i.e. ESM imports across project files work fine:
```ts
// src/main.mjs
import printStuff from './printStuff.js'
printStuff('it works!')
// src/printStuff.js
import logger from './logger.js'
export default function printStuff(...stuff) {
logger(...stuff)
}
// src/logger.js
export default function logger(...args) {
console.log(...args)
}
```
Some findings:
- `const { default: printStuff } = await import('my-esm-dependency')` doesn't work out of the box, but it does work when setting `process.noAsar = true` before importing. Moving the import into the `app.whenReady` callback also doesn't work
- `import printStuff from 'my-esm-dependency'` doesn't work at all, not even with `process.noAsar = true`
- This is not limited to ESM entrypoints. I also get the same errors on the `commonjs-entrypoint` branch, and changing to Electron 27.0.0 fixes the problem.

[Bug]: Electron 28 breaks `import` of transitive dependencies inside ES modules
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
28.0.0-alpha.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
27.0.0
### Expected Behavior
Importing an ESM dependency which imports some other dependency (ESM or CJS) should work from inside `app.asar`
### Actual Behavior
The module lookup starts at ```node_modules/<directory where the dependency's `main` file lives>/node_modules```, doesn't find the transitive dependency there and then crashes, never reaching the top-level `node_modules` which is where the transitive dependency actually lives:
### Testcase Gist URL
_No response_
### Additional Information
I've run into this using [this repro](https://github.com/electron/asar/issues/249#issuecomment-1434998313), where the ESM dependency `got` is imported causing the app to crash when looking for the transitive ESM dependency `@sindresorhus/is`. I've put together a minimal reproduction with two local dependencies, which should make it easier to test different variables: https://github.com/erikian/esm-asar-demo
Note that this problem seems to be limited to dependencies inside `node_modules`, i.e. ESM imports across project files work fine:
```ts
// src/main.mjs
import printStuff from './printStuff.js'
printStuff('it works!')
// src/printStuff.js
import logger from './logger.js'
export default function printStuff(...stuff) {
logger(...stuff)
}
// src/logger.js
export default function logger(...args) {
console.log(...args)
}
```
Some findings:
- `const { default: printStuff } = await import('my-esm-dependency')` doesn't work out of the box, but it does work when setting `process.noAsar = true` before importing. Moving the import into the `app.whenReady` callback also doesn't work
- `import printStuff from 'my-esm-dependency'` doesn't work at all, not even with `process.noAsar = true`
- This is not limited to ESM entrypoints. I also get the same errors on the `commonjs-entrypoint` branch, and changing to Electron 27.0.0 fixes the problem.

[Bug]: Electron 28 breaks `import` of transitive dependencies inside ES modules
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
28.0.0-alpha.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
27.0.0
### Expected Behavior
Importing an ESM dependency which imports some other dependency (ESM or CJS) should work from inside `app.asar`
### Actual Behavior
The module lookup starts at ```node_modules/<directory where the dependency's `main` file lives>/node_modules```, doesn't find the transitive dependency there and then crashes, never reaching the top-level `node_modules` which is where the transitive dependency actually lives:
### Testcase Gist URL
_No response_
### Additional Information
I've run into this using [this repro](https://github.com/electron/asar/issues/249#issuecomment-1434998313), where the ESM dependency `got` is imported causing the app to crash when looking for the transitive ESM dependency `@sindresorhus/is`. I've put together a minimal reproduction with two local dependencies, which should make it easier to test different variables: https://github.com/erikian/esm-asar-demo
Note that this problem seems to be limited to dependencies inside `node_modules`, i.e. ESM imports across project files work fine:
```ts
// src/main.mjs
import printStuff from './printStuff.js'
printStuff('it works!')
// src/printStuff.js
import logger from './logger.js'
export default function printStuff(...stuff) {
logger(...stuff)
}
// src/logger.js
export default function logger(...args) {
console.log(...args)
}
```
Some findings:
- `const { default: printStuff } = await import('my-esm-dependency')` doesn't work out of the box, but it does work when setting `process.noAsar = true` before importing. Moving the import into the `app.whenReady` callback also doesn't work
- `import printStuff from 'my-esm-dependency'` doesn't work at all, not even with `process.noAsar = true`
- This is not limited to ESM entrypoints. I also get the same errors on the `commonjs-entrypoint` branch, and changing to Electron 27.0.0 fixes the problem.

### Electron Version
26.3.0, 27.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 22H2 (22621.2361)
### What arch are you using?
x64
### Last Known Working Electron version
11.x
### Expected Behavior
1. Create Notification with `Electron.Notification`.
2. Wait for the notification popup to disappear and be logged to the Windows notification center.
3. Call `Electron.Notification.close()` on it
The notification is removed from the Windows notification center and the "unread" count in the taskbar decreases
### Actual Behavior
The notification remains in the Windows notification center and the unread count does not change.
### Testcase Gist URL
https://gist.github.com/474863b1c8a398ee00a74950596ab0c3
### Additional Information
Duplicated of #29557, #32260 (These issues are marked as "stale", but still occurred)

# Notification
> Create OS desktop notifications
Process: [Main](../glossary.md#main-process)
:::info Renderer process notifications
If you want to show notifications from a renderer process you should use the
[web Notifications API](../tutorial/notifications.md)
:::
## Class: Notification
> Create OS desktop notifications
Process: [Main](../glossary.md#main-process)
`Notification` is an [EventEmitter][event-emitter].
It creates a new `Notification` with native properties as set by the `options`.
### Static Methods
The `Notification` class has the following static methods:
#### `Notification.isSupported()`
Returns `boolean` - Whether or not desktop notifications are supported on the current system
### `new Notification([options])`
* `options` Object (optional)
* `title` string (optional) - A title for the notification, which will be displayed at the top of the notification window when it is shown.
* `subtitle` string (optional) _macOS_ - A subtitle for the notification, which will be displayed below the title.
* `body` string (optional) - The body text of the notification, which will be displayed below the title or subtitle.
* `silent` boolean (optional) - Whether or not to suppress the OS notification noise when showing the notification.
* `icon` (string | [NativeImage](native-image.md)) (optional) - An icon to use in the notification.
* `hasReply` boolean (optional) _macOS_ - Whether or not to add an inline reply option to the notification.
* `timeoutType` string (optional) _Linux_ _Windows_ - The timeout duration of the notification. Can be 'default' or 'never'.
* `replyPlaceholder` string (optional) _macOS_ - The placeholder to write in the inline reply input field.
* `sound` string (optional) _macOS_ - The name of the sound file to play when the notification is shown.
* `urgency` string (optional) _Linux_ - The urgency level of the notification. Can be 'normal', 'critical', or 'low'.
* `actions` [NotificationAction[]](structures/notification-action.md) (optional) _macOS_ - Actions to add to the notification. Please read the available actions and limitations in the `NotificationAction` documentation.
* `closeButtonText` string (optional) _macOS_ - A custom title for the close button of an alert. An empty string will cause the default localized text to be used.
* `toastXml` string (optional) _Windows_ - A custom description of the Notification on Windows superseding all properties above. Provides full customization of design and behavior of the notification.
### Instance Events
Objects created with `new Notification` emit the following events:
:::info
Some events are only available on specific operating systems and are labeled as such.
:::
#### Event: 'show'
Returns:
* `event` Event
Emitted when the notification is shown to the user. Note that this event can be fired
multiple times as a notification can be shown multiple times through the
`show()` method.
#### Event: 'click'
Returns:
* `event` Event
Emitted when the notification is clicked by the user.
#### Event: 'close'
Returns:
* `event` Event
Emitted when the notification is closed by manual intervention from the user.
This event is not guaranteed to be emitted in all cases where the notification
is closed.
#### Event: 'reply' _macOS_
Returns:
* `event` Event
* `reply` string - The string the user entered into the inline reply field.
Emitted when the user clicks the "Reply" button on a notification with `hasReply: true`.
#### Event: 'action' _macOS_
Returns:
* `event` Event
* `index` number - The index of the action that was activated.
#### Event: 'failed' _Windows_
Returns:
* `event` Event
* `error` string - The error encountered during execution of the `show()` method.
Emitted when an error is encountered while creating and showing the native notification.
### Instance Methods
Objects created with the `new Notification()` constructor have the following instance methods:
#### `notification.show()`
Immediately shows the notification to the user. Unlike the web notification API,
instantiating a `new Notification()` does not immediately show it to the user. Instead, you need to
call this method before the OS will display it.
If the notification has been shown before, this method will dismiss the previously
shown notification and create a new one with identical properties.
#### `notification.close()`
Dismisses the notification.
### Instance Properties
#### `notification.title`
A `string` property representing the title of the notification.
#### `notification.subtitle`
A `string` property representing the subtitle of the notification.
#### `notification.body`
A `string` property representing the body of the notification.
#### `notification.replyPlaceholder`
A `string` property representing the reply placeholder of the notification.
#### `notification.sound`
A `string` property representing the sound of the notification.
#### `notification.closeButtonText`
A `string` property representing the close button text of the notification.
#### `notification.silent`
A `boolean` property representing whether the notification is silent.
#### `notification.hasReply`
A `boolean` property representing whether the notification has a reply action.
#### `notification.urgency` _Linux_
A `string` property representing the urgency level of the notification. Can be 'normal', 'critical', or 'low'.
Default is 'low' - see [NotifyUrgency](https://developer-old.gnome.org/notification-spec/#urgency-levels) for more information.
#### `notification.timeoutType` _Linux_ _Windows_
A `string` property representing the type of timeout duration for the notification. Can be 'default' or 'never'.
If `timeoutType` is set to 'never', the notification never expires. It stays open until closed by the calling API or the user.
#### `notification.actions`
A [`NotificationAction[]`](structures/notification-action.md) property representing the actions of the notification.
#### `notification.toastXml` _Windows_
A `string` property representing the custom Toast XML of the notification.
### Playing Sounds
On macOS, you can specify the name of the sound you'd like to play when the
notification is shown. Any of the default sounds (under System Preferences >
Sound) can be used, in addition to custom sound files. Be sure that the sound
file is copied under the app bundle (e.g., `YourApp.app/Contents/Resources`),
or one of the following locations:
* `~/Library/Sounds`
* `/Library/Sounds`
* `/Network/Library/Sounds`
* `/System/Library/Sounds`
See the [`NSSound`](https://developer.apple.com/documentation/appkit/nssound) docs for more information.

[Bug]: notification.close() does not work in Windows after the popup has disappeared
|
### Preflight Checklist

- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
26.3.0, 27.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 22H2 (22621.2361)
### What arch are you using?
x64
### Last Known Working Electron version
11.x
### Expected Behavior
1. Create Notification with `Electron.Notification`.
2. Wait for the notification popup to disappear and be logged to the Windows notification center.
3. Call `Electron.Notification.close()` on it
The notification is removed from the Windows notification center and the "unread" count in the taskbar decreases
### Actual Behavior
The notification remains in the Windows notification center and the unread count does not change.
### Testcase Gist URL
https://gist.github.com/474863b1c8a398ee00a74950596ab0c3
### Additional Information
Duplicated of #29557, #32260 (These issues are marked as "stale", but still occurred)

### Electron Version
26.3.0, 27.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 22H2 (22621.2361)
### What arch are you using?

### Last Known Working Electron version
11.x
### Expected Behavior
1. Create Notification with `Electron.Notification`.
2. Wait for the notification popup to disappear and be logged to the Windows notification center.
3. Call `Electron.Notification.close()` on it
The notification is removed from the Windows notification center and the "unread" count in the taskbar decreases
### Actual Behavior
The notification remains in the Windows notification center and the unread count does not change.
### Testcase Gist URL

### Electron Version
26.3.0, 27.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 22H2 (22621.2361)
### What arch are you using?
x64
### Last Known Working Electron version
11.x
### Expected Behavior
1. Create Notification with `Electron.Notification`.
2. Wait for the notification popup to disappear and be logged to the Windows notification center.
3. Call `Electron.Notification.close()` on it
The notification is removed from the Windows notification center and the "unread" count in the taskbar decreases
### Actual Behavior
The notification remains in the Windows notification center and the unread count does not change.
### Testcase Gist URL

# Notification
> Create OS desktop notifications
Process: [Main](../glossary.md#main-process)
:::info Renderer process notifications
If you want to show notifications from a renderer process you should use the
[web Notifications API](../tutorial/notifications.md)
:::
## Class: Notification
> Create OS desktop notifications
Process: [Main](../glossary.md#main-process)
`Notification` is an [EventEmitter][event-emitter].
It creates a new `Notification` with native properties as set by the `options`.
### Static Methods
The `Notification` class has the following static methods:
#### `Notification.isSupported()`
Returns `boolean` - Whether or not desktop notifications are supported on the current system
### `new Notification([options])`
* `options` Object (optional)
* `title` string (optional) - A title for the notification, which will be displayed at the top of the notification window when it is shown.
* `subtitle` string (optional) _macOS_ - A subtitle for the notification, which will be displayed below the title.
* `body` string (optional) - The body text of the notification, which will be displayed below the title or subtitle.
* `silent` boolean (optional) - Whether or not to suppress the OS notification noise when showing the notification.
* `icon` (string | [NativeImage](native-image.md)) (optional) - An icon to use in the notification.
* `hasReply` boolean (optional) _macOS_ - Whether or not to add an inline reply option to the notification.
* `timeoutType` string (optional) _Linux_ _Windows_ - The timeout duration of the notification. Can be 'default' or 'never'.
* `replyPlaceholder` string (optional) _macOS_ - The placeholder to write in the inline reply input field.
* `sound` string (optional) _macOS_ - The name of the sound file to play when the notification is shown.
* `urgency` string (optional) _Linux_ - The urgency level of the notification. Can be 'normal', 'critical', or 'low'.
* `actions` [NotificationAction[]](structures/notification-action.md) (optional) _macOS_ - Actions to add to the notification. Please read the available actions and limitations in the `NotificationAction` documentation.
* `closeButtonText` string (optional) _macOS_ - A custom title for the close button of an alert. An empty string will cause the default localized text to be used.
* `toastXml` string (optional) _Windows_ - A custom description of the Notification on Windows superseding all properties above. Provides full customization of design and behavior of the notification.
### Instance Events
Objects created with `new Notification` emit the following events:
:::info
Some events are only available on specific operating systems and are labeled as such.
:::
#### Event: 'show'
Returns:
* `event` Event
Emitted when the notification is shown to the user. Note that this event can be fired
multiple times as a notification can be shown multiple times through the
`show()` method.
#### Event: 'click'
Returns:
* `event` Event
Emitted when the notification is clicked by the user.
#### Event: 'close'
Returns:
* `event` Event
Emitted when the notification is closed by manual intervention from the user.
This event is not guaranteed to be emitted in all cases where the notification
is closed.
#### Event: 'reply' _macOS_
Returns:
* `event` Event
* `reply` string - The string the user entered into the inline reply field.
Emitted when the user clicks the "Reply" button on a notification with `hasReply: true`.
#### Event: 'action' _macOS_
Returns:
* `event` Event
* `index` number - The index of the action that was activated.
#### Event: 'failed' _Windows_
Returns:
* `event` Event
* `error` string - The error encountered during execution of the `show()` method.
Emitted when an error is encountered while creating and showing the native notification.
### Instance Methods
Objects created with the `new Notification()` constructor have the following instance methods:
#### `notification.show()`
Immediately shows the notification to the user. Unlike the web notification API,
instantiating a `new Notification()` does not immediately show it to the user. Instead, you need to
call this method before the OS will display it.
If the notification has been shown before, this method will dismiss the previously
shown notification and create a new one with identical properties.
#### `notification.close()`
Dismisses the notification.
### Instance Properties
#### `notification.title`
A `string` property representing the title of the notification.
#### `notification.subtitle`
A `string` property representing the subtitle of the notification.
#### `notification.body`
A `string` property representing the body of the notification.
#### `notification.replyPlaceholder`
A `string` property representing the reply placeholder of the notification.
#### `notification.sound`
A `string` property representing the sound of the notification.
#### `notification.closeButtonText`
A `string` property representing the close button text of the notification.
#### `notification.silent`
A `boolean` property representing whether the notification is silent.
#### `notification.hasReply`
A `boolean` property representing whether the notification has a reply action.
#### `notification.urgency` _Linux_
A `string` property representing the urgency level of the notification. Can be 'normal', 'critical', or 'low'.
Default is 'low' - see [NotifyUrgency](https://developer-old.gnome.org/notification-spec/#urgency-levels) for more information.
#### `notification.timeoutType` _Linux_ _Windows_
A `string` property representing the type of timeout duration for the notification. Can be 'default' or 'never'.
If `timeoutType` is set to 'never', the notification never expires. It stays open until closed by the calling API or the user.
#### `notification.actions`
A [`NotificationAction[]`](structures/notification-action.md) property representing the actions of the notification.
#### `notification.toastXml` _Windows_
A `string` property representing the custom Toast XML of the notification.
### Playing Sounds
On macOS, you can specify the name of the sound you'd like to play when the
notification is shown. Any of the default sounds (under System Preferences >
Sound) can be used, in addition to custom sound files. Be sure that the sound
file is copied under the app bundle (e.g., `YourApp.app/Contents/Resources`),
or one of the following locations:
* `~/Library/Sounds`
* `/Library/Sounds`
* `/Network/Library/Sounds`
* `/System/Library/Sounds`
See the [`NSSound`](https://developer.apple.com/documentation/appkit/nssound) docs for more information.

### Operating System Version
Windows 11 22H2 (22621.2361)
### What arch are you using?
x64
### Last Known Working Electron version
11.x
### Expected Behavior
1. Create Notification with `Electron.Notification`.
2. Wait for the notification popup to disappear and be logged to the Windows notification center.
3. Call `Electron.Notification.close()` on it
The notification is removed from the Windows notification center and the "unread" count in the taskbar decreases
### Actual Behavior
The notification remains in the Windows notification center and the unread count does not change.
### Testcase Gist URL
https://gist.github.com/474863b1c8a398ee00a74950596ab0c3
### Additional Information
Duplicated of #29557, #32260 (These issues are marked as "stale", but still occurred)

[Bug]: notification.close() does not work in Windows after the popup has disappeared
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
26.3.0, 27.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 22H2 (22621.2361)
### What arch are you using?
x64
### Last Known Working Electron version
11.x
### Expected Behavior
1. Create Notification with `Electron.Notification`.
2. Wait for the notification popup to disappear and be logged to the Windows notification center.
3. Call `Electron.Notification.close()` on it
The notification is removed from the Windows notification center and the "unread" count in the taskbar decreases
### Actual Behavior
The notification remains in the Windows notification center and the unread count does not change.
### Testcase Gist URL
https://gist.github.com/474863b1c8a398ee00a74950596ab0c3
### Additional Information
Duplicated of #29557, #32260 (These issues are marked as "stale", but still occurred)

[Bug]: the example in the document of represented file creates BrowserWindow twice
|
doc link: https://www.electronjs.org/docs/latest/tutorial/represented-file
code: https://github.com/electron/electron/blob/d8e7457ab0fa13b16d7c8e10395dd315e6fe2077/docs/fiddles/features/represented-file/main.js#L4-L18
The code in the example creates BrowserWindow both in the `createWindow` function and after `app.whenReady()`, which not loads `index.html` properly.

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist

- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL
_No response_

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist

### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL
_No response_
### Additional Information

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL
_No response_
### Additional Information
_No response_

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL
_No response_

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL
_No response_
### Additional Information

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL
_No response_
### Additional Information

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL
_No response_
### Additional Information

[Bug]: NativeImage methods returned by capturePage fail with "Error: Illegal invocation"
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
22.0.0
### What operating system are you using?
Ubuntu
### Operating System Version
Ubuntu 23.04
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
While calling `<webview-tag>.capturePage()` from renderer process, we should be able to run methods from the returned NativeImage (like `.getSize()`)
### Actual Behavior
While calling `<webview-tag>.capturePage()` from a renderer process, all of the NativeImage methods return the following error. In this example we call `.getSize()`:
```
Uncaught (in promise) Error: Illegal invocation: Function must be called on an object of type NativeImage
```
**Code snippet**
```js
const webviewElement = document.getElementById("webview")
webviewElement.capturePage()
.then((image) => console.log(image.getSize()))
```
**To reproduce**
**1.** Create a webview element in a page (BrowserView) and make set the id-attribute to `webview`
**2.** Execute the snippet above
### Testcase Gist URL
_No response_
### Additional Information
_No response_

[Bug]: Navigator.keyboard.lock() icw requestFullscreen does not change behavior to 'Press and Hold Escape'
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro version 22H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When an element is brought to fullscreen with:
[elem.requestFullscreen()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen)
and an event listener exists like:
```
document.addEventListener('fullscreenchange', async () => {
const nav: any = navigator;
const elem = document.getElementById('app');
if (elem) {
await nav.keyboard.lock(['Escape']);
return;
}
nav.keyboard.unlock();
});
```
I would expect that the behavior of the Esc key changes, where I would now need to press and hold Esc for a few seconds before fullscreen is actually exited. As described here: [https://developer.chrome.com/blog/better-full-screen-mode/](https://developer.chrome.com/blog/better-full-screen-mode/)
I imagine the same behavior change should hold for when [requestPointerLock()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestPointerLock) is used.
### Actual Behavior
When the Esc key is pressed after bringing an element to fullscreen, it ALWAYS exits fullscreen immediately, even when used in combination with [keyboard.lock() API](https://developer.mozilla.org/en-US/docs/Web/API/Keyboard/lock).
### Testcase Gist URL

[Bug]: Navigator.keyboard.lock() icw requestFullscreen does not change behavior to 'Press and Hold Escape'
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro version 22H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When an element is brought to fullscreen with:
[elem.requestFullscreen()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen)
and an event listener exists like:
```
document.addEventListener('fullscreenchange', async () => {
const nav: any = navigator;
const elem = document.getElementById('app');
if (elem) {
await nav.keyboard.lock(['Escape']);
return;
}
nav.keyboard.unlock();
});
```
I would expect that the behavior of the Esc key changes, where I would now need to press and hold Esc for a few seconds before fullscreen is actually exited. As described here: [https://developer.chrome.com/blog/better-full-screen-mode/](https://developer.chrome.com/blog/better-full-screen-mode/)
I imagine the same behavior change should hold for when [requestPointerLock()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestPointerLock) is used.
### Actual Behavior
When the Esc key is pressed after bringing an element to fullscreen, it ALWAYS exits fullscreen immediately, even when used in combination with [keyboard.lock() API](https://developer.mozilla.org/en-US/docs/Web/API/Keyboard/lock).

[Bug]: Navigator.keyboard.lock() icw requestFullscreen does not change behavior to 'Press and Hold Escape'
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro version 22H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When an element is brought to fullscreen with:
[elem.requestFullscreen()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen)
and an event listener exists like:
```
document.addEventListener('fullscreenchange', async () => {
const nav: any = navigator;
const elem = document.getElementById('app');
if (elem) {
await nav.keyboard.lock(['Escape']);
return;
}
nav.keyboard.unlock();
});
```
I would expect that the behavior of the Esc key changes, where I would now need to press and hold Esc for a few seconds before fullscreen is actually exited. As described here: [https://developer.chrome.com/blog/better-full-screen-mode/](https://developer.chrome.com/blog/better-full-screen-mode/)
I imagine the same behavior change should hold for when [requestPointerLock()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestPointerLock) is used.
### Actual Behavior
When the Esc key is pressed after bringing an element to fullscreen, it ALWAYS exits fullscreen immediately, even when used in combination with [keyboard.lock() API](https://developer.mozilla.org/en-US/docs/Web/API/Keyboard/lock).

### Electron Version
27.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro version 22H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When an element is brought to fullscreen with:
[elem.requestFullscreen()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen)
and an event listener exists like:
```
document.addEventListener('fullscreenchange', async () => {
const nav: any = navigator;
const elem = document.getElementById('app');
if (elem) {
await nav.keyboard.lock(['Escape']);
return;
}
nav.keyboard.unlock();
});
```
I would expect that the behavior of the Esc key changes, where I would now need to press and hold Esc for a few seconds before fullscreen is actually exited. As described here: [https://developer.chrome.com/blog/better-full-screen-mode/](https://developer.chrome.com/blog/better-full-screen-mode/)
I imagine the same behavior change should hold for when [requestPointerLock()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestPointerLock) is used.
### Actual Behavior
When the Esc key is pressed after bringing an element to fullscreen, it ALWAYS exits fullscreen immediately, even when used in combination with [keyboard.lock() API](https://developer.mozilla.org/en-US/docs/Web/API/Keyboard/lock).

[Bug]: Navigator.keyboard.lock() icw requestFullscreen does not change behavior to 'Press and Hold Escape'
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro version 22H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When an element is brought to fullscreen with:
[elem.requestFullscreen()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen)
and an event listener exists like:
```
document.addEventListener('fullscreenchange', async () => {
const nav: any = navigator;
const elem = document.getElementById('app');
if (elem) {
await nav.keyboard.lock(['Escape']);
return;
}
nav.keyboard.unlock();
});
```
I would expect that the behavior of the Esc key changes, where I would now need to press and hold Esc for a few seconds before fullscreen is actually exited. As described here: [https://developer.chrome.com/blog/better-full-screen-mode/](https://developer.chrome.com/blog/better-full-screen-mode/)
I imagine the same behavior change should hold for when [requestPointerLock()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestPointerLock) is used.
### Actual Behavior
When the Esc key is pressed after bringing an element to fullscreen, it ALWAYS exits fullscreen immediately, even when used in combination with [keyboard.lock() API](https://developer.mozilla.org/en-US/docs/Web/API/Keyboard/lock).
### Testcase Gist URL

[Bug]: Navigator.keyboard.lock() icw requestFullscreen does not change behavior to 'Press and Hold Escape'
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro version 22H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When an element is brought to fullscreen with:
[elem.requestFullscreen()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen)
and an event listener exists like:
```
document.addEventListener('fullscreenchange', async () => {
const nav: any = navigator;
const elem = document.getElementById('app');
if (elem) {
await nav.keyboard.lock(['Escape']);
return;
}
nav.keyboard.unlock();
});
```
I would expect that the behavior of the Esc key changes, where I would now need to press and hold Esc for a few seconds before fullscreen is actually exited. As described here: [https://developer.chrome.com/blog/better-full-screen-mode/](https://developer.chrome.com/blog/better-full-screen-mode/)
I imagine the same behavior change should hold for when [requestPointerLock()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestPointerLock) is used.
### Actual Behavior
When the Esc key is pressed after bringing an element to fullscreen, it ALWAYS exits fullscreen immediately, even when used in combination with [keyboard.lock() API](https://developer.mozilla.org/en-US/docs/Web/API/Keyboard/lock).

[Bug]: Navigator.keyboard.lock() icw requestFullscreen does not change behavior to 'Press and Hold Escape'
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a bug report that matches the one I want to file, without success.
### Electron Version
27.0.2
### What operating system are you using?
Windows
### Operating System Version
Windows 10 Pro version 22H2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When an element is brought to fullscreen with:
[elem.requestFullscreen()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestFullscreen)
and an event listener exists like:
```
document.addEventListener('fullscreenchange', async () => {
const nav: any = navigator;
const elem = document.getElementById('app');
if (elem) {
await nav.keyboard.lock(['Escape']);
return;
}
nav.keyboard.unlock();
});
```
I would expect that the behavior of the Esc key changes, where I would now need to press and hold Esc for a few seconds before fullscreen is actually exited. As described here: [https://developer.chrome.com/blog/better-full-screen-mode/](https://developer.chrome.com/blog/better-full-screen-mode/)
I imagine the same behavior change should hold for when [requestPointerLock()](https://developer.mozilla.org/en-US/docs/Web/API/Element/requestPointerLock) is used.
### Actual Behavior
When the Esc key is pressed after bringing an element to fullscreen, it ALWAYS exits fullscreen immediately, even when used in combination with [keyboard.lock() API](https://developer.mozilla.org/en-US/docs/Web/API/Keyboard/lock).

[Feature Request]: Set ELECTRON_USE_REMOTE_CHECKSUMS from `.npmrc`
|
### Preflight Checklist
- [X] I have read the [Contributing Guidelines](https://github.com/electron/electron/blob/main/CONTRIBUTING.md) for this project.
- [X] I agree to follow the [Code of Conduct](https://github.com/electron/electron/blob/main/CODE_OF_CONDUCT.md) that this project adheres to.
- [X] I have searched the [issue tracker](https://www.github.com/electron/electron/issues) for a feature request that matches the one I want to file, without success.
### Problem Description
Starting with Electron 15 consuming custom electron binaries from a custom mirror requires setting the `ELECTRON_USE_REMOTE_CHECKSUMS` environment variable, otherwise the checksum match fails.
Specifying environment variables is cumbersome across all dev and CI hosts.
### Proposed Solution
If the electron installer script also looked at the `.npmrc` it would be a one time configuration option for the project and wouldn't require additional step (of setting env variable) during dev host setup.
@electron/get allows setting the mirror options this way.
### Alternatives Considered
Other option could be an npm package config, which would also work.
@electron/get also allows setting the mirror options this way.
### Additional Information

# Advanced Installation Instructions
To install prebuilt Electron binaries, use [`npm`][npm].
The preferred method is to install Electron as a development dependency in your
app:
```sh
npm install electron --save-dev
```
See the [Electron versioning doc][versioning] for info on how to
manage Electron versions in your apps.
## Running Electron ad-hoc
If you're in a pinch and would prefer to not use `npm install` in your local
project, you can also run Electron ad-hoc using the [`npx`][npx] command runner
bundled with `npm`:
```sh
npx electron .
```
The above command will run the current working directory with Electron. Note that
any dependencies in your app will not be installed.
## Customization
If you want to change the architecture that is downloaded (e.g., `ia32` on an
`x64` machine), you can use the `--arch` flag with npm install or set the
`npm_config_arch` environment variable:
```shell
npm install --arch=ia32 electron
```
In addition to changing the architecture, you can also specify the platform
(e.g., `win32`, `linux`, etc.) using the `--platform` flag:
```shell
npm install --platform=win32 electron
```
## Proxies
If you need to use an HTTP proxy, you need to set the `ELECTRON_GET_USE_PROXY` variable to any
value, plus additional environment variables depending on your host system's Node version:
* [Node 10 and above][proxy-env-10]
* [Before Node 10][proxy-env]
## Custom Mirrors and Caches
During installation, the `electron` module will call out to
[`@electron/get`][electron-get] to download prebuilt binaries of
Electron for your platform. It will do so by contacting GitHub's
release download page (`https://github.com/electron/electron/releases/tag/v$VERSION`,
where `$VERSION` is the exact version of Electron).
If you are unable to access GitHub or you need to provide a custom build, you
can do so by either providing a mirror or an existing cache directory.
#### Mirror
You can use environment variables to override the base URL, the path at which to
look for Electron binaries, and the binary filename. The URL used by `@electron/get`
is composed as follows:
```javascript @ts-nocheck
url = ELECTRON_MIRROR + ELECTRON_CUSTOM_DIR + '/' + ELECTRON_CUSTOM_FILENAME
```
For instance, to use the China CDN mirror:
```shell
ELECTRON_MIRROR="https://npmmirror.com/mirrors/electron/"
```
By default, `ELECTRON_CUSTOM_DIR` is set to `v$VERSION`. To change the format,
use the `{{ version }}` placeholder. For example, `version-{{ version }}`
resolves to `version-5.0.0`, `{{ version }}` resolves to `5.0.0`, and
`v{{ version }}` is equivalent to the default. As a more concrete example, to
use the China non-CDN mirror:
```shell
ELECTRON_MIRROR="https://npmmirror.com/mirrors/electron/"
ELECTRON_CUSTOM_DIR="{{ version }}"
```
The above configuration will download from URLs such as
`https://npmmirror.com/mirrors/electron/8.0.0/electron-v8.0.0-linux-x64.zip`.
If your mirror serves artifacts with different checksums to the official
Electron release you may have to set `electron_use_remote_checksums=1` to
force Electron to use the remote `SHASUMS256.txt` file to verify the checksum
instead of the embedded checksums.
#### Cache
Alternatively, you can override the local cache. `@electron/get` will cache
downloaded binaries in a local directory to not stress your network. You can use
that cache folder to provide custom builds of Electron or to avoid making contact
with the network at all.
* Linux: `$XDG_CACHE_HOME` or `~/.cache/electron/`
* macOS: `~/Library/Caches/electron/`
* Windows: `$LOCALAPPDATA/electron/Cache` or `~/AppData/Local/electron/Cache/`
On environments that have been using older versions of Electron, you might find the
cache also in `~/.electron`.
You can also override the local cache location by providing a `electron_config_cache`
environment variable.
The cache contains the version's official zip file as well as a checksum, and is stored as
`[checksum]/[filename]`. A typical cache might look like this:
```sh
βββ a91b089b5dc5b1279966511344b805ec84869b6cd60af44f800b363bba25b915
β βββ electron-v15.3.1-darwin-x64.zip
```
## Skip binary download
Under the hood, Electron's JavaScript API binds to a binary that contains its
implementations. Because this binary is crucial to the function of any Electron app,
it is downloaded by default in the `postinstall` step every time you install `electron`
from the npm registry.
However, if you want to install your project's dependencies but don't need to use
Electron functionality, you can set the `ELECTRON_SKIP_BINARY_DOWNLOAD` environment
variable to prevent the binary from being downloaded. For instance, this feature can
be useful in continuous integration environments when running unit tests that mock
out the `electron` module.
```sh npm2yarn
ELECTRON_SKIP_BINARY_DOWNLOAD=1 npm install
```
## Troubleshooting
When running `npm install electron`, some users occasionally encounter
installation errors.
In almost all cases, these errors are the result of network problems and not
actual issues with the `electron` npm package. Errors like `ELIFECYCLE`,
`EAI_AGAIN`, `ECONNRESET`, and `ETIMEDOUT` are all indications of such
network problems. The best resolution is to try switching networks, or
wait a bit and try installing again.
You can also attempt to download Electron directly from
[electron/electron/releases][releases]
if installing via `npm` is failing.
If installation fails with an `EACCESS` error you may need to
[fix your npm permissions][npm-permissions].
If the above error persists, the [unsafe-perm][unsafe-perm] flag may need to be
set to true:
```sh
sudo npm install electron --unsafe-perm=true
```
On slower networks, it may be advisable to use the `--verbose` flag in order to
show download progress:
```sh
npm install --verbose electron
```
If you need to force a re-download of the asset and the SHASUM file set the
`force_no_cache` environment variable to `true`.
