### Electron Version

### What operating system are you using?
Windows
### Operating System Version
Windows 11 22H2
### What arch are you using?
x64
### Last Known Working Electron version
25.1.1
### Expected Behavior
After clicking on an item in the application menu, the menu should open *below* that item.
### Actual Behavior
The menu overlaps the clicked item. See screenshot below. This just doesn't look nice but also decreases the usability.
### Testcase Gist URL
_No response_
### Additional Information
Electron versions between 26.0.0-alpha.1 and 26.0.0-alpha.7 display the menu as expected. 26.0.0-alpha.8 and newer also have this bug.
I don't think it is necessary to upload a repro repo (ask for that, if I'm wrong). In Electron Fiddle, I just needed to select the right Electron version.

Subject: fix: crash on nativeTheme change during context menu close
Refs https://chromium-review.googlesource.com/c/chromium/src/+/4363385
Fixes a crash seen when trying to change nativeTheme source during
a context menu close. This happens as a result of a change added in the
above CL, which doesn't check whether or not the menu controller could
possibly be null as can happen during a context menu close. This
only affects Windows 11, as Bubble Border is only enabled there.
This should be upstreamed, as other uses of MenuController in this
file do check for menu controller being null.

### Electron Version

### What operating system are you using?
Windows
### Operating System Version
Windows 11 22H2
### What arch are you using?
x64
### Last Known Working Electron version
24.5.0
### Expected Behavior
The application changes the theme, e.g. the application menu is colored accordingly and it doesn't crash.
### Actual Behavior
As soon the theme is changed via the application menu, the application crashes. On the console appears following output:
```
[36016:0612/045936.512:ERROR:crashpad_client_win.cc(844)] not connected
```
### Testcase Gist URL
https://gist.github.com/c9e0ce78e7811ce716923f4ad7111c8c
### Additional Information
Selecting the currently used theme has no effect.
This bug was introduced with Electron 25.0.0-alpha.1
Electron 26.0.0-alpha.5 is still affected as are (probably) all versions in between (I didn't try all).

macOS
### Operating System Version
Ventura 13.3.1
### What arch are you using?

`New Notification('title'); // note that there is no options.`
The notification in the top-right screen should only show a popup with the title.
<img width="364" alt="image" src="https://github.com/electron/electron/assets/28861842/2190fb95-4ffe-4ad4-b04f-b4e7ea51103a">

### Actual Behavior
- The notification popup show with an action button named: 'show' when I hover the popup.
- If I click, there is no action trigger

[Bug]: Notification auto adds the action button 'show' in MacOS
|
### 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
25.2.0
### What operating system are you using?
macOS
### Operating System Version
Ventura 13.3.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
22.3.1
### Expected Behavior
Create a notification:
`New Notification('title'); // note that there is no options.`
The notification in the top-right screen should only show a popup with the title.
<img width="364" alt="image" src="https://github.com/electron/electron/assets/28861842/2190fb95-4ffe-4ad4-b04f-b4e7ea51103a">
for bellow example, click the 'click me' button to execute `noti` fn
### Actual Behavior
- The notification popup show with an action button named: 'show' when I hover the popup.
- If I click, there is no action trigger
<img width="369" alt="image" src="https://github.com/electron/electron/assets/28861842/7426041d-d1e4-4630-9666-c8124d820e8f">
### Testcase Gist URL
https://gist.github.com/319ccca16a8cd1ec6263adc2723e994e
### Additional Information
I think this issue is caused by this commit: https://github.com/electron/electron/commit/8fb0f430301578ba94b175f0b097fb2752f5ddf9
`[notification_ setHasActionButton:false];`
removed, but as my research, the default of this value is true. We need to set it to false in case there are no actions added

[Bug]: print() crashes on Windows, but works 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
25.2.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
webContents.print() should work and print page:)
### Actual Behavior
in doesnt. When I call print(), app crashes silently. I can't catch any logs, even with process uncaughtException/unhandledRejection events.
### Testcase Gist URL
_No response_
### Additional Information
I have created new empty project to test this bug. I have empty project with only one window. I just load image to the window and try to print it.
```
const createWindow = () => {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
});
mainWindow.loadURL(
"https://www.kasandbox.org/programming-images/avatars/leaf-blue.png"
);
mainWindow.webContents.openDevTools();
mainWindow.webContents.on("did-finish-load", () => {
console.log("did-finish-load");
mainWindow.webContents.print({
// silent: true,
// deviceName: "Xprinter XP-365B",
});
});
};
```
I have tested it in different environments and different electron version (including latest ^26.0.0-beta.1). I works on macOS and always crashes on Windows (I've tried different versions: win 10, win 11, parallels, etc).
Can you give me an advice, how it can be fixed?

Subject: printing.patch
Add changeset that was previously applied to sources in chromium_src. The
majority of changes originally come from these PRs:
* https://github.com/electron/electron/pull/1835
* https://github.com/electron/electron/pull/8596
This patch also fixes callback for manual user cancellation and success.

[Bug]: print() crashes on Windows, but works 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
25.2.0
### What operating system are you using?
Windows
### Operating System Version
Windows 10
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
webContents.print() should work and print page:)
### Actual Behavior
in doesnt. When I call print(), app crashes silently. I can't catch any logs, even with process uncaughtException/unhandledRejection events.
### Testcase Gist URL
_No response_
### Additional Information
I have created new empty project to test this bug. I have empty project with only one window. I just load image to the window and try to print it.
```
const createWindow = () => {
const mainWindow = new BrowserWindow({
width: 800,
height: 600,
});
mainWindow.loadURL(
"https://www.kasandbox.org/programming-images/avatars/leaf-blue.png"
);
mainWindow.webContents.openDevTools();
mainWindow.webContents.on("did-finish-load", () => {
console.log("did-finish-load");
mainWindow.webContents.print({
// silent: true,
// deviceName: "Xprinter XP-365B",
});
});
};
```
I have tested it in different environments and different electron version (including latest ^26.0.0-beta.1). I works on macOS and always crashes on Windows (I've tried different versions: win 10, win 11, parallels, etc).
Can you give me an advice, how it can be fixed?

Subject: printing.patch
Add changeset that was previously applied to sources in chromium_src. The
majority of changes originally come from these PRs:
* https://github.com/electron/electron/pull/1835
* https://github.com/electron/electron/pull/8596
This patch also fixes callback for manual user cancellation and success.

### Electron Version
23.1.1
### What operating system are you using?
Ubuntu
### Operating System Version
22.04.2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Get access to screens for capture recording using desktopCapturer in electron Api
### Actual Behavior
There are difficulties to report the problem because no specific error is received in the terminal, only the message below
```bash
tiago@tghpereira:~/Área de Trabalho/electron/test$ yarn start
yarn run v1.22.19
$ electron .
/home/tiago/Área de Trabalho/electron/test/node_modules/electron/dist/electron exited with signal SIGSEGV
error Command failed with exit code 1.
```
I followed the official Electronjs documentation step by step and tried several approaches mentioned in forums to find ways to solve the problem, but without success.
Please help us with this issue which is greatly affecting many packages.

### 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
23.1.1
### What operating system are you using?
Ubuntu
### Operating System Version
22.04.2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Get access to screens for capture recording using desktopCapturer in electron Api
### Actual Behavior
There are difficulties to report the problem because no specific error is received in the terminal, only the message below
```bash
tiago@tghpereira:~/Área de Trabalho/electron/test$ yarn start
yarn run v1.22.19
$ electron .
/home/tiago/Área de Trabalho/electron/test/node_modules/electron/dist/electron exited with signal SIGSEGV
error Command failed with exit code 1.
```
I followed the official Electronjs documentation step by step and tried several approaches mentioned in forums to find ways to solve the problem, but without success.
Please help us with this issue which is greatly affecting many packages.

[Bug]: DesktopCapturer doesn't work in Ubuntu 22.04.2 LTS
|
### 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
23.1.1
### What operating system are you using?
Ubuntu
### Operating System Version
22.04.2
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
Get access to screens for capture recording using desktopCapturer in electron Api
### Actual Behavior
There are difficulties to report the problem because no specific error is received in the terminal, only the message below
```bash
tiago@tghpereira:~/Área de Trabalho/electron/test$ yarn start
yarn run v1.22.19
$ electron .
/home/tiago/Área de Trabalho/electron/test/node_modules/electron/dist/electron exited with signal SIGSEGV
error Command failed with exit code 1.
```
I followed the official Electronjs documentation step by step and tried several approaches mentioned in forums to find ways to solve the problem, but without success.
Please help us with this issue which is greatly affecting many packages.

[Bug]: protocol.handle() is not working with file protocol
|
### 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
25.2.0
### What operating system are you using?
Other Linux
### Operating System Version
6.4.1-arch2-1
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When using `protocol.handle()` to intercept the `file` protocol, the handler should be called and `handle()` should be intercepting the request.
### Actual Behavior
`protocol.handle()` is not calling the handler and the request finishes without going through the interceptor.
### Testcase Gist URL
https://gist.github.com/Aasim-A/87b30a9acf3b4cbc61e8102290f9197b
### Additional Information
When I try to do the same thing with `http` or any custom protocol, it works without any issues.

[Bug]: protocol.handle() is not working with file protocol
|
### 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
25.2.0
### What operating system are you using?
Other Linux
### Operating System Version
6.4.1-arch2-1
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When using `protocol.handle()` to intercept the `file` protocol, the handler should be called and `handle()` should be intercepting the request.
### Actual Behavior
`protocol.handle()` is not calling the handler and the request finishes without going through the interceptor.
### Testcase Gist URL
https://gist.github.com/Aasim-A/87b30a9acf3b4cbc61e8102290f9197b
### Additional Information
When I try to do the same thing with `http` or any custom protocol, it works without any issues.

[Bug]: protocol.handle() is not working with file protocol
|
### 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
25.2.0
### What operating system are you using?
Other Linux
### Operating System Version
6.4.1-arch2-1
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
When using `protocol.handle()` to intercept the `file` protocol, the handler should be called and `handle()` should be intercepting the request.
### Actual Behavior
`protocol.handle()` is not calling the handler and the request finishes without going through the interceptor.
### Testcase Gist URL
https://gist.github.com/Aasim-A/87b30a9acf3b4cbc61e8102290f9197b
### Additional Information
When I try to do the same thing with `http` or any custom protocol, it works without any issues.

Attempt to use proxyquire in tests with electron of version 23 an higher leads to the following error message:
```
TypeError: Script methods can only be called on script instances.

### Testcase Gist URL
https://gist.github.com/kyrylo-hrechykhin/f0afe7c469145c51d4df39fbea97ec95
### Additional Information
#### Workarounds:
- avoid calling window.open method completely
- separate electron-mocha runs to the one where window.open method is called and the one where proxyquire is used. If it happens in two different files, it is easy to do.
#### Details:
Issue is probably caused by node version upgrade in electron 23. But as it worked in electron 22, I consider it as a regression. I also could not reproduce this issue in non-electron environment.
#### Run testcase gist locally:
Run the following commands in the folder where all the files specified in the attached gist.
```
yarn
yarn start
```
Please upgrade/downgrade electron versions to see actual/expected results.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: deepak1556 <[email protected]>
Date: Wed, 28 Jun 2023 21:11:40 +0900
Subject: fix: harden blink::ScriptState::MaybeFrom
This is needed as side effect of https://chromium-review.googlesource.com/c/chromium/src/+/4609446
which now gets blink::ExecutionContext from blink::ScriptState
and there are isolate callbacks which get entered from Node.js
environment that has v8::Context not associated with blink::ScriptState.
Some examples are ModifyCodeGenerationFromStrings in node_bindings.cc,
blink::UseCounterCallback etc.
Without this patch when blink::ScriptState::MaybeFrom tries to extract
blink::ScriptState from the provided v8::Context and since Node.js has context
embedder data fields with index greater than blink (see node_context_data.h)
leading to the following CHECK failure.
```
script_state.h(169)] Security Check Failed: script_state
```
This patch adds a new tag in the context associated with ScriptState
to uniquely identify. It is based on what Node.js does to identify the
context created by it in `node_context_data.h`.
PS: We are not performing a check like
```
ScriptState* script_state =
static_cast<ScriptState*>(context->GetAlignedPointerFromEmbedderData(
kV8ContextPerContextDataIndex));
if (!script_state) {
return nullptr;
}
```
since in 32-bit builds which does not have v8 sandbox enabled unlike 64-bit builds,
the embedder data slot will not lazy initialize indexes in the former. This means
accessing uninitialized lower indexes can return garbage values that cannot be null checked.
Refer to v8::EmbedderDataSlot::store_aligned_pointer for context.

### Electron Version
23.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11, Version22H2, OS Build 22621.1265
### What arch are you using?

### Last Known Working Electron version
22.3.1
### Expected Behavior
proxyquire should load modules as it does with electron version 22.3.1.
### Actual Behavior
Attempt to use proxyquire in tests with electron of version 23 an higher leads to the following error message:
```

```
### Testcase Gist URL
https://gist.github.com/kyrylo-hrechykhin/f0afe7c469145c51d4df39fbea97ec95
### Additional Information
#### Workarounds:
- avoid calling window.open method completely
- separate electron-mocha runs to the one where window.open method is called and the one where proxyquire is used. If it happens in two different files, it is easy to do.
#### Details:
Issue is probably caused by node version upgrade in electron 23. But as it worked in electron 22, I consider it as a regression. I also could not reproduce this issue in non-electron environment.
#### Run testcase gist locally:
Run the following commands in the folder where all the files specified in the attached gist.
```
yarn
yarn start
```
Please upgrade/downgrade electron versions to see actual/expected results.

### Testcase Gist URL
https://gist.github.com/kyrylo-hrechykhin/f0afe7c469145c51d4df39fbea97ec95
### Additional Information
#### Workarounds:
- avoid calling window.open method completely
- separate electron-mocha runs to the one where window.open method is called and the one where proxyquire is used. If it happens in two different files, it is easy to do.
#### Details:
Issue is probably caused by node version upgrade in electron 23. But as it worked in electron 22, I consider it as a regression. I also could not reproduce this issue in non-electron environment.
#### Run testcase gist locally:
Run the following commands in the folder where all the files specified in the attached gist.
```
yarn
yarn start
```
Please upgrade/downgrade electron versions to see actual/expected results.

### Electron Version
23.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11, Version22H2, OS Build 22621.1265
### What arch are you using?
x64
### Last Known Working Electron version
22.3.1
### Expected Behavior
proxyquire should load modules as it does with electron version 22.3.1.
### Actual Behavior
Attempt to use proxyquire in tests with electron of version 23 an higher leads to the following error message:
```
TypeError: Script methods can only be called on script instances.

[Bug]: Uncaught illegal state exception and renderer crash with node immediates and closing child window

### Electron Version
13.x, 17.x, 22.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 (22621.963)
### What arch are you using?
x64
### Last Known Working Electron version
Unknown
### Expected Behavior
Closing a child window should not produce an 'Uncaught illegal state' exception. Furthermore, it shouldn't cause the renderer process to exit with code 7 (which can specifically occur if there is a node native immediate being used, see additional information below).
### Actual Behavior
A race condition can occur when using `setImmediate` (or using a node module that sets up native immediates) in a node environment and closing a child window that has a separate node environment (but shares the underlying isolate and event loop).
Note: This seems to occur when the BrowserWindow webPreferences sandbox is set to false.
The behavior here is that the console will report `Uncaught illegal state` and in certain cases the renderer process will simply exit with code 7. The following was also reported to stderr:
```
illegal access
(Use `electron --trace-uncaught ...` to show where the exception was thrown)
```
### Testcase Gist URL
https://gist.github.com/markh-discord/1bb303c57d1a20aeee95aeedbc403ab3
### Additional Information
Note: This seems to occur only when the main BrowserWindow webPreferences sandbox is set to false.
The reproduce project in the gist may require a few attempts, but when clicking the button to open the window it will automatically close. Around 1-10 attempts may be needed to display the error in the console. To improve the simplicity of this I used Javascript `setImmediate` which seems to be more recoverable as it doesn't exit the process. In the steps below there is a node native immediate being setup by the node https module that does cause the renderer process to eventually exit.
Reproduce steps aren't precise since this is a race condition, however the following path seems to hit this:
1. node `Environment A` is created and `Environment::InitializeLibuv` is run and sets up its `Environment::CheckImmediate` method in `uv_check_start`.
a. This will be interesting later, but it's called via the event loop `uv_run`: https://github.com/libuv/libuv/blob/e972c6705f197e12d211b598fc514bbea051425d/src/win/core.c#L645
1. Window is opened, a new node Environment (I'll call `Environment B`) is created: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/renderer/electron_renderer_client.cc#L91-L92
a. This environment uses the existing `NodeBindings::isolate_data_`, which also shares the isolate and uv_loop_ from `Environment A`: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/common/node_bindings.cc#L493
2. node `Environment A` has a native immediate pushed from http post work being done by the node http module.
a. This can occur in a few places via `env()->SetImmediate(...)`, here's one as an example: https://github.com/nodejs/node/blob/e8db11c5b2169931238db6c02f6d7f80b3c6e759/src/crypto/crypto_tls.cc#L593
3. Window is closed, causing `Environment B` to begin cleanup:
a. `node::FreeEnvironment` is called, and sets up JS to be disallowed: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/api/environment.cc#L420-L421
b. `node::CleanupHandles` is eventually called, this starts up the event loop via `uv_run`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#LL966C21-L966C21
c. Per 1a above, the `uv_check_invoke` is called, and the `Environment A`'s `CheckImmediate` is run
4. At this point we're now running things from `Environment A`, in particular it will begin executing the native immediates that it has. Note that we're still in the same call stack and the isolate's state to disallow JS is still flagged.
5. Since a native immediate was added in step 2 above, this begins running, eventually for the http stream work it tries to callback into Javascript via `node::ReportWritesToJSStreamListener::OnStreamAfterReqFinished`:
a. https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/stream_base.cc#L632
6. This then fails the check on if JS is allowed to be executed (setup on shared isolate from `Environment B` in step 3a):
a. https://chromium.googlesource.com/v8/v8/+/roll/src/execution.cc
```
if (!ThrowOnJavascriptExecution::IsAllowed(isolate)) {
isolate->ThrowIllegalOperation();
```
7. Call stack begins unwinding and eventually hits: `errors::TriggerUncaughtException`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#L1097
8. This in turn attempts to execute a `fatal_exception_function.As<Function>()->Call`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1126-L1127
a. Since JS is still disallowed we get _another_ `v8::internal::Isolate::ThrowIllegalOperation` triggered
9. This unwinds and executes the `TryCatchScope` dtor setup in the above scope: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1116-L1117
10. The `TryCatchScope::~TryCatchScope` then builds the message to dumps and eventually causes the `env_->Exit` to be called: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L572
11. This then runs the `Environment::Exit` and eventually will exit the process: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#L1548

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: deepak1556 <[email protected]>
Date: Wed, 28 Jun 2023 21:11:40 +0900
Subject: fix: harden blink::ScriptState::MaybeFrom
This is needed as side effect of https://chromium-review.googlesource.com/c/chromium/src/+/4609446
which now gets blink::ExecutionContext from blink::ScriptState
and there are isolate callbacks which get entered from Node.js
environment that has v8::Context not associated with blink::ScriptState.
Some examples are ModifyCodeGenerationFromStrings in node_bindings.cc,
blink::UseCounterCallback etc.
Without this patch when blink::ScriptState::MaybeFrom tries to extract
blink::ScriptState from the provided v8::Context and since Node.js has context
embedder data fields with index greater than blink (see node_context_data.h)
leading to the following CHECK failure.
```
script_state.h(169)] Security Check Failed: script_state
```
This patch adds a new tag in the context associated with ScriptState
to uniquely identify. It is based on what Node.js does to identify the
context created by it in `node_context_data.h`.
PS: We are not performing a check like
```
ScriptState* script_state =
static_cast<ScriptState*>(context->GetAlignedPointerFromEmbedderData(
kV8ContextPerContextDataIndex));
if (!script_state) {
return nullptr;
}
```
since in 32-bit builds which does not have v8 sandbox enabled unlike 64-bit builds,
the embedder data slot will not lazy initialize indexes in the former. This means
accessing uninitialized lower indexes can return garbage values that cannot be null checked.
Refer to v8::EmbedderDataSlot::store_aligned_pointer for context.

[Bug]: Uncaught illegal state exception and renderer crash with node immediates and closing child window
|
### 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
13.x, 17.x, 22.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 (22621.963)
### What arch are you using?
x64
### Last Known Working Electron version
Unknown
### Expected Behavior
Closing a child window should not produce an 'Uncaught illegal state' exception. Furthermore, it shouldn't cause the renderer process to exit with code 7 (which can specifically occur if there is a node native immediate being used, see additional information below).
### Actual Behavior
A race condition can occur when using `setImmediate` (or using a node module that sets up native immediates) in a node environment and closing a child window that has a separate node environment (but shares the underlying isolate and event loop).
Note: This seems to occur when the BrowserWindow webPreferences sandbox is set to false.
The behavior here is that the console will report `Uncaught illegal state` and in certain cases the renderer process will simply exit with code 7. The following was also reported to stderr:
```
illegal access
(Use `electron --trace-uncaught ...` to show where the exception was thrown)
```
### Testcase Gist URL
https://gist.github.com/markh-discord/1bb303c57d1a20aeee95aeedbc403ab3
### Additional Information
Note: This seems to occur only when the main BrowserWindow webPreferences sandbox is set to false.
The reproduce project in the gist may require a few attempts, but when clicking the button to open the window it will automatically close. Around 1-10 attempts may be needed to display the error in the console. To improve the simplicity of this I used Javascript `setImmediate` which seems to be more recoverable as it doesn't exit the process. In the steps below there is a node native immediate being setup by the node https module that does cause the renderer process to eventually exit.
Reproduce steps aren't precise since this is a race condition, however the following path seems to hit this:
1. node `Environment A` is created and `Environment::InitializeLibuv` is run and sets up its `Environment::CheckImmediate` method in `uv_check_start`.
a. This will be interesting later, but it's called via the event loop `uv_run`: https://github.com/libuv/libuv/blob/e972c6705f197e12d211b598fc514bbea051425d/src/win/core.c#L645
1. Window is opened, a new node Environment (I'll call `Environment B`) is created: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/renderer/electron_renderer_client.cc#L91-L92
a. This environment uses the existing `NodeBindings::isolate_data_`, which also shares the isolate and uv_loop_ from `Environment A`: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/common/node_bindings.cc#L493
2. node `Environment A` has a native immediate pushed from http post work being done by the node http module.
a. This can occur in a few places via `env()->SetImmediate(...)`, here's one as an example: https://github.com/nodejs/node/blob/e8db11c5b2169931238db6c02f6d7f80b3c6e759/src/crypto/crypto_tls.cc#L593
3. Window is closed, causing `Environment B` to begin cleanup:
a. `node::FreeEnvironment` is called, and sets up JS to be disallowed: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/api/environment.cc#L420-L421
b. `node::CleanupHandles` is eventually called, this starts up the event loop via `uv_run`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#LL966C21-L966C21
c. Per 1a above, the `uv_check_invoke` is called, and the `Environment A`'s `CheckImmediate` is run
4. At this point we're now running things from `Environment A`, in particular it will begin executing the native immediates that it has. Note that we're still in the same call stack and the isolate's state to disallow JS is still flagged.
5. Since a native immediate was added in step 2 above, this begins running, eventually for the http stream work it tries to callback into Javascript via `node::ReportWritesToJSStreamListener::OnStreamAfterReqFinished`:
a. https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/stream_base.cc#L632
6. This then fails the check on if JS is allowed to be executed (setup on shared isolate from `Environment B` in step 3a):
a. https://chromium.googlesource.com/v8/v8/+/roll/src/execution.cc
```
if (!ThrowOnJavascriptExecution::IsAllowed(isolate)) {
isolate->ThrowIllegalOperation();
```
7. Call stack begins unwinding and eventually hits: `errors::TriggerUncaughtException`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#L1097
8. This in turn attempts to execute a `fatal_exception_function.As<Function>()->Call`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1126-L1127
a. Since JS is still disallowed we get _another_ `v8::internal::Isolate::ThrowIllegalOperation` triggered
9. This unwinds and executes the `TryCatchScope` dtor setup in the above scope: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1116-L1117
10. The `TryCatchScope::~TryCatchScope` then builds the message to dumps and eventually causes the `env_->Exit` to be called: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L572
11. This then runs the `Environment::Exit` and eventually will exit the process: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#L1548

[Bug]: Uncaught illegal state exception and renderer crash with node immediates and closing child window
|
### 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
13.x, 17.x, 22.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 (22621.963)
### What arch are you using?
x64
### Last Known Working Electron version
Unknown
### Expected Behavior
Closing a child window should not produce an 'Uncaught illegal state' exception. Furthermore, it shouldn't cause the renderer process to exit with code 7 (which can specifically occur if there is a node native immediate being used, see additional information below).
### Actual Behavior
A race condition can occur when using `setImmediate` (or using a node module that sets up native immediates) in a node environment and closing a child window that has a separate node environment (but shares the underlying isolate and event loop).
Note: This seems to occur when the BrowserWindow webPreferences sandbox is set to false.
The behavior here is that the console will report `Uncaught illegal state` and in certain cases the renderer process will simply exit with code 7. The following was also reported to stderr:
```
illegal access
(Use `electron --trace-uncaught ...` to show where the exception was thrown)
```
### Testcase Gist URL
https://gist.github.com/markh-discord/1bb303c57d1a20aeee95aeedbc403ab3
### Additional Information
Note: This seems to occur only when the main BrowserWindow webPreferences sandbox is set to false.
The reproduce project in the gist may require a few attempts, but when clicking the button to open the window it will automatically close. Around 1-10 attempts may be needed to display the error in the console. To improve the simplicity of this I used Javascript `setImmediate` which seems to be more recoverable as it doesn't exit the process. In the steps below there is a node native immediate being setup by the node https module that does cause the renderer process to eventually exit.
Reproduce steps aren't precise since this is a race condition, however the following path seems to hit this:
1. node `Environment A` is created and `Environment::InitializeLibuv` is run and sets up its `Environment::CheckImmediate` method in `uv_check_start`.
a. This will be interesting later, but it's called via the event loop `uv_run`: https://github.com/libuv/libuv/blob/e972c6705f197e12d211b598fc514bbea051425d/src/win/core.c#L645
1. Window is opened, a new node Environment (I'll call `Environment B`) is created: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/renderer/electron_renderer_client.cc#L91-L92
a. This environment uses the existing `NodeBindings::isolate_data_`, which also shares the isolate and uv_loop_ from `Environment A`: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/common/node_bindings.cc#L493
2. node `Environment A` has a native immediate pushed from http post work being done by the node http module.
a. This can occur in a few places via `env()->SetImmediate(...)`, here's one as an example: https://github.com/nodejs/node/blob/e8db11c5b2169931238db6c02f6d7f80b3c6e759/src/crypto/crypto_tls.cc#L593
3. Window is closed, causing `Environment B` to begin cleanup:
a. `node::FreeEnvironment` is called, and sets up JS to be disallowed: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/api/environment.cc#L420-L421
b. `node::CleanupHandles` is eventually called, this starts up the event loop via `uv_run`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#LL966C21-L966C21
c. Per 1a above, the `uv_check_invoke` is called, and the `Environment A`'s `CheckImmediate` is run
4. At this point we're now running things from `Environment A`, in particular it will begin executing the native immediates that it has. Note that we're still in the same call stack and the isolate's state to disallow JS is still flagged.
5. Since a native immediate was added in step 2 above, this begins running, eventually for the http stream work it tries to callback into Javascript via `node::ReportWritesToJSStreamListener::OnStreamAfterReqFinished`:
a. https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/stream_base.cc#L632
6. This then fails the check on if JS is allowed to be executed (setup on shared isolate from `Environment B` in step 3a):
a. https://chromium.googlesource.com/v8/v8/+/roll/src/execution.cc
```
if (!ThrowOnJavascriptExecution::IsAllowed(isolate)) {
isolate->ThrowIllegalOperation();
```
7. Call stack begins unwinding and eventually hits: `errors::TriggerUncaughtException`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#L1097
8. This in turn attempts to execute a `fatal_exception_function.As<Function>()->Call`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1126-L1127
a. Since JS is still disallowed we get _another_ `v8::internal::Isolate::ThrowIllegalOperation` triggered
9. This unwinds and executes the `TryCatchScope` dtor setup in the above scope: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1116-L1117
10. The `TryCatchScope::~TryCatchScope` then builds the message to dumps and eventually causes the `env_->Exit` to be called: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L572

a. This will be interesting later, but it's called via the event loop `uv_run`: https://github.com/libuv/libuv/blob/e972c6705f197e12d211b598fc514bbea051425d/src/win/core.c#L645
1. Window is opened, a new node Environment (I'll call `Environment B`) is created: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/renderer/electron_renderer_client.cc#L91-L92
a. This environment uses the existing `NodeBindings::isolate_data_`, which also shares the isolate and uv_loop_ from `Environment A`: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/common/node_bindings.cc#L493
2. node `Environment A` has a native immediate pushed from http post work being done by the node http module.
a. This can occur in a few places via `env()->SetImmediate(...)`, here's one as an example: https://github.com/nodejs/node/blob/e8db11c5b2169931238db6c02f6d7f80b3c6e759/src/crypto/crypto_tls.cc#L593
3. Window is closed, causing `Environment B` to begin cleanup:
a. `node::FreeEnvironment` is called, and sets up JS to be disallowed: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/api/environment.cc#L420-L421
b. `node::CleanupHandles` is eventually called, this starts up the event loop via `uv_run`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#LL966C21-L966C21
c. Per 1a above, the `uv_check_invoke` is called, and the `Environment A`'s `CheckImmediate` is run
4. At this point we're now running things from `Environment A`, in particular it will begin executing the native immediates that it has. Note that we're still in the same call stack and the isolate's state to disallow JS is still flagged.
5. Since a native immediate was added in step 2 above, this begins running, eventually for the http stream work it tries to callback into Javascript via `node::ReportWritesToJSStreamListener::OnStreamAfterReqFinished`:
a. https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/stream_base.cc#L632
6. This then fails the check on if JS is allowed to be executed (setup on shared isolate from `Environment B` in step 3a):
a. https://chromium.googlesource.com/v8/v8/+/roll/src/execution.cc
```
if (!ThrowOnJavascriptExecution::IsAllowed(isolate)) {
isolate->ThrowIllegalOperation();
```
7. Call stack begins unwinding and eventually hits: `errors::TriggerUncaughtException`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#L1097
8. This in turn attempts to execute a `fatal_exception_function.As<Function>()->Call`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1126-L1127
a. Since JS is still disallowed we get _another_ `v8::internal::Isolate::ThrowIllegalOperation` triggered
9. This unwinds and executes the `TryCatchScope` dtor setup in the above scope: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1116-L1117
10. The `TryCatchScope::~TryCatchScope` then builds the message to dumps and eventually causes the `env_->Exit` to be called: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L572
11. This then runs the `Environment::Exit` and eventually will exit the process: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#L1548

[Bug]: Uncaught illegal state exception and renderer crash with node immediates and closing child window
|
### 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
13.x, 17.x, 22.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11 (22621.963)
### What arch are you using?
x64
### Last Known Working Electron version
Unknown
### Expected Behavior
Closing a child window should not produce an 'Uncaught illegal state' exception. Furthermore, it shouldn't cause the renderer process to exit with code 7 (which can specifically occur if there is a node native immediate being used, see additional information below).
### Actual Behavior
A race condition can occur when using `setImmediate` (or using a node module that sets up native immediates) in a node environment and closing a child window that has a separate node environment (but shares the underlying isolate and event loop).
Note: This seems to occur when the BrowserWindow webPreferences sandbox is set to false.
The behavior here is that the console will report `Uncaught illegal state` and in certain cases the renderer process will simply exit with code 7. The following was also reported to stderr:
```
illegal access
(Use `electron --trace-uncaught ...` to show where the exception was thrown)
```
### Testcase Gist URL
https://gist.github.com/markh-discord/1bb303c57d1a20aeee95aeedbc403ab3
### Additional Information
Note: This seems to occur only when the main BrowserWindow webPreferences sandbox is set to false.
The reproduce project in the gist may require a few attempts, but when clicking the button to open the window it will automatically close. Around 1-10 attempts may be needed to display the error in the console. To improve the simplicity of this I used Javascript `setImmediate` which seems to be more recoverable as it doesn't exit the process. In the steps below there is a node native immediate being setup by the node https module that does cause the renderer process to eventually exit.
Reproduce steps aren't precise since this is a race condition, however the following path seems to hit this:
1. node `Environment A` is created and `Environment::InitializeLibuv` is run and sets up its `Environment::CheckImmediate` method in `uv_check_start`.

1. Window is opened, a new node Environment (I'll call `Environment B`) is created: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/renderer/electron_renderer_client.cc#L91-L92
a. This environment uses the existing `NodeBindings::isolate_data_`, which also shares the isolate and uv_loop_ from `Environment A`: https://github.com/electron/electron/blob/dfe501941cd9e7092829c3ef8e27e322047cf736/shell/common/node_bindings.cc#L493

3. Window is closed, causing `Environment B` to begin cleanup:
a. `node::FreeEnvironment` is called, and sets up JS to be disallowed: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/api/environment.cc#L420-L421

a. https://chromium.googlesource.com/v8/v8/+/roll/src/execution.cc
```
if (!ThrowOnJavascriptExecution::IsAllowed(isolate)) {
isolate->ThrowIllegalOperation();
```
7. Call stack begins unwinding and eventually hits: `errors::TriggerUncaughtException`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/env.cc#L1097
8. This in turn attempts to execute a `fatal_exception_function.As<Function>()->Call`: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1126-L1127
a. Since JS is still disallowed we get _another_ `v8::internal::Isolate::ThrowIllegalOperation` triggered
9. This unwinds and executes the `TryCatchScope` dtor setup in the above scope: https://github.com/nodejs/node/blob/2af83ea0f8a1594c0d0bf4bc4b3035234bcd895e/src/node_errors.cc#L1116-L1117

[Bug]: proxyquire can't load modules after window.open method is called
|
### 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
23.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11, Version22H2, OS Build 22621.1265
### What arch are you using?
x64
### Last Known Working Electron version
22.3.1
### Expected Behavior
proxyquire should load modules as it does with electron version 22.3.1.
### Actual Behavior
Attempt to use proxyquire in tests with electron of version 23 an higher leads to the following error message:
```
TypeError: Script methods can only be called on script instances.

### Testcase Gist URL
https://gist.github.com/kyrylo-hrechykhin/f0afe7c469145c51d4df39fbea97ec95
### Additional Information
#### Workarounds:
- avoid calling window.open method completely
- separate electron-mocha runs to the one where window.open method is called and the one where proxyquire is used. If it happens in two different files, it is easy to do.
#### Details:
Issue is probably caused by node version upgrade in electron 23. But as it worked in electron 22, I consider it as a regression. I also could not reproduce this issue in non-electron environment.
#### Run testcase gist locally:
Run the following commands in the folder where all the files specified in the attached gist.
```
yarn
yarn start
```
Please upgrade/downgrade electron versions to see actual/expected results.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: deepak1556 <[email protected]>
Date: Wed, 28 Jun 2023 21:11:40 +0900
Subject: fix: harden blink::ScriptState::MaybeFrom
This is needed as side effect of https://chromium-review.googlesource.com/c/chromium/src/+/4609446
which now gets blink::ExecutionContext from blink::ScriptState
and there are isolate callbacks which get entered from Node.js
environment that has v8::Context not associated with blink::ScriptState.
Some examples are ModifyCodeGenerationFromStrings in node_bindings.cc,
blink::UseCounterCallback etc.
Without this patch when blink::ScriptState::MaybeFrom tries to extract
blink::ScriptState from the provided v8::Context and since Node.js has context
embedder data fields with index greater than blink (see node_context_data.h)
leading to the following CHECK failure.
```
script_state.h(169)] Security Check Failed: script_state
```
This patch adds a new tag in the context associated with ScriptState
to uniquely identify. It is based on what Node.js does to identify the
context created by it in `node_context_data.h`.
PS: We are not performing a check like
```
ScriptState* script_state =
static_cast<ScriptState*>(context->GetAlignedPointerFromEmbedderData(
kV8ContextPerContextDataIndex));
if (!script_state) {
return nullptr;
}
```
since in 32-bit builds which does not have v8 sandbox enabled unlike 64-bit builds,
the embedder data slot will not lazy initialize indexes in the former. This means
accessing uninitialized lower indexes can return garbage values that cannot be null checked.
Refer to v8::EmbedderDataSlot::store_aligned_pointer for context.

[Bug]: proxyquire can't load modules after window.open method is called
|
### 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
23.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11, Version22H2, OS Build 22621.1265
### What arch are you using?
x64
### Last Known Working Electron version
22.3.1
### Expected Behavior
proxyquire should load modules as it does with electron version 22.3.1.
### Actual Behavior
Attempt to use proxyquire in tests with electron of version 23 an higher leads to the following error message:
```
TypeError: Script methods can only be called on script instances.

### Testcase Gist URL
https://gist.github.com/kyrylo-hrechykhin/f0afe7c469145c51d4df39fbea97ec95
### Additional Information
#### Workarounds:
- avoid calling window.open method completely
- separate electron-mocha runs to the one where window.open method is called and the one where proxyquire is used. If it happens in two different files, it is easy to do.
#### Details:
Issue is probably caused by node version upgrade in electron 23. But as it worked in electron 22, I consider it as a regression. I also could not reproduce this issue in non-electron environment.
#### Run testcase gist locally:
Run the following commands in the folder where all the files specified in the attached gist.
```
yarn
yarn start
```
Please upgrade/downgrade electron versions to see actual/expected results.

### Electron Version
23.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11, Version22H2, OS Build 22621.1265
### What arch are you using?

### Expected Behavior
proxyquire should load modules as it does with electron version 22.3.1.
### Actual Behavior
Attempt to use proxyquire in tests with electron of version 23 an higher leads to the following error message:
```

### Testcase Gist URL
https://gist.github.com/kyrylo-hrechykhin/f0afe7c469145c51d4df39fbea97ec95
### Additional Information
#### Workarounds:
- avoid calling window.open method completely
- separate electron-mocha runs to the one where window.open method is called and the one where proxyquire is used. If it happens in two different files, it is easy to do.
#### Details:
Issue is probably caused by node version upgrade in electron 23. But as it worked in electron 22, I consider it as a regression. I also could not reproduce this issue in non-electron environment.
#### Run testcase gist locally:
Run the following commands in the folder where all the files specified in the attached gist.
```
yarn

### Electron Version
23.0.0
### What operating system are you using?
Windows
### Operating System Version
Windows 11, Version22H2, OS Build 22621.1265
### What arch are you using?
x64
### Last Known Working Electron version
22.3.1
### Expected Behavior
proxyquire should load modules as it does with electron version 22.3.1.
### Actual Behavior
Attempt to use proxyquire in tests with electron of version 23 an higher leads to the following error message:
```
TypeError: Script methods can only be called on script instances.

### Testcase Gist URL
https://gist.github.com/kyrylo-hrechykhin/f0afe7c469145c51d4df39fbea97ec95
### Additional Information
#### Workarounds:
- avoid calling window.open method completely
- separate electron-mocha runs to the one where window.open method is called and the one where proxyquire is used. If it happens in two different files, it is easy to do.
#### Details:
Issue is probably caused by node version upgrade in electron 23. But as it worked in electron 22, I consider it as a regression. I also could not reproduce this issue in non-electron environment.
#### Run testcase gist locally:
Run the following commands in the folder where all the files specified in the attached gist.
```
yarn
yarn start
```
Please upgrade/downgrade electron versions to see actual/expected results.

[Feature Request]: Use combined PipeWire Picker for desktopCapturer when windows and screens are requested
|
### 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
When calling `desktopCapturer.getSources({ types: ['window', 'screen'] })` it opens two PipeWire pickers, one for a window and one for a screen. It can't get the sources if one of them is canceled (e.g. the user only wants to share a window or screen and cancels the other one).
### Proposed Solution
Use a combined picker if a window and screen capture is requested.
My Pseudo Idea how this could be implemented:
Add a check in [electron_api_desktop_capturer.cc](https://github.com/aiddya/electron/blob/72f357ad773056483518964820700672465a048f/shell/browser/api/electron_api_desktop_capturer.cc#L240) if capture_window and capture_screen are true and a delegated Sourcelist is used.
Then somehow pass `ScreenCastPortal::CaptureSourceType::kAnyScreenContent` as a CaptureType in [screencast_portal.cc](https://webrtc.googlesource.com/src/+/8fcc6df79daf1810cd4ecdb8d2ef1d361abfdc9c/modules/desktop_capture/linux/wayland/screencast_portal.cc#95)
### Alternatives Considered
Ignore if one of the pickers gets canceled.
### Additional Information
Fixing behavior that was out of scope of #38833

[Feature Request]: Use combined PipeWire Picker for desktopCapturer when windows and screens are requested
|
### 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
When calling `desktopCapturer.getSources({ types: ['window', 'screen'] })` it opens two PipeWire pickers, one for a window and one for a screen. It can't get the sources if one of them is canceled (e.g. the user only wants to share a window or screen and cancels the other one).
### Proposed Solution
Use a combined picker if a window and screen capture is requested.
My Pseudo Idea how this could be implemented:
Add a check in [electron_api_desktop_capturer.cc](https://github.com/aiddya/electron/blob/72f357ad773056483518964820700672465a048f/shell/browser/api/electron_api_desktop_capturer.cc#L240) if capture_window and capture_screen are true and a delegated Sourcelist is used.
Then somehow pass `ScreenCastPortal::CaptureSourceType::kAnyScreenContent` as a CaptureType in [screencast_portal.cc](https://webrtc.googlesource.com/src/+/8fcc6df79daf1810cd4ecdb8d2ef1d361abfdc9c/modules/desktop_capture/linux/wayland/screencast_portal.cc#95)
### Alternatives Considered
Ignore if one of the pickers gets canceled.
### Additional Information

[Feature Request]: Use combined PipeWire Picker for desktopCapturer when windows and screens are requested
|
### 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
When calling `desktopCapturer.getSources({ types: ['window', 'screen'] })` it opens two PipeWire pickers, one for a window and one for a screen. It can't get the sources if one of them is canceled (e.g. the user only wants to share a window or screen and cancels the other one).
### Proposed Solution
Use a combined picker if a window and screen capture is requested.
My Pseudo Idea how this could be implemented:
Add a check in [electron_api_desktop_capturer.cc](https://github.com/aiddya/electron/blob/72f357ad773056483518964820700672465a048f/shell/browser/api/electron_api_desktop_capturer.cc#L240) if capture_window and capture_screen are true and a delegated Sourcelist is used.
Then somehow pass `ScreenCastPortal::CaptureSourceType::kAnyScreenContent` as a CaptureType in [screencast_portal.cc](https://webrtc.googlesource.com/src/+/8fcc6df79daf1810cd4ecdb8d2ef1d361abfdc9c/modules/desktop_capture/linux/wayland/screencast_portal.cc#95)
### Alternatives Considered
Ignore if one of the pickers gets canceled.
### Additional Information

**Notes:**
* The `-alpha.1`, `-beta.1`, and `stable` dates are our solid release dates.
* We strive for weekly alpha/beta releases, but we often release more than scheduled.
* All dates are our goals but there may be reasons for adjusting the stable deadline, such as security bugs.
**Historical changes:**
* Since Electron 5, Electron has been publicizing its release dates ([see blog post](https://electronjs.org/blog/electron-5-0-timeline)).
* Since Electron 6, Electron major versions have been targeting every other Chromium major version. Each Electron stable should happen on the same day as Chrome stable ([see blog post](https://www.electronjs.org/blog/12-week-cadence)).
* Since Electron 16, Electron has been releasing major versions on an 8-week cadence in accordance to Chrome's change to a 4-week release cadence ([see blog post](https://www.electronjs.org/blog/8-week-cadence)).
:::info Chrome release dates
Chromium has the own public release schedule [here](https://chromiumdash.appspot.com/schedule).
:::
## Version support policy
:::info
The Electron team will temporarily support Electron 22 until October 10, 2023.
This extended support is intended to help Electron developers who still need
support for Windows 7/8/8.1, which ended support in Electron 23. The October
support date follows the extended support dates from both Chromium and Microsoft.
On October 11, the Electron team will drop support back to the latest three
stable major versions.
:::
The latest three _stable_ major versions are supported by the Electron team.
For example, if the latest release is 6.1.x, then the 5.0.x as well
as the 4.2.x series are supported. We only support the latest minor release
for each stable release series. This means that in the case of a security fix,
6.1.x will receive the fix, but we will not release a new version of 6.0.x.
The latest stable release unilaterally receives all fixes from `main`,
and the version prior to that receives the vast majority of those fixes
as time and bandwidth warrants. The oldest supported release line will receive
only security fixes directly.
### Breaking API changes
When an API is changed or removed in a way that breaks existing functionality, the
previous functionality will be supported for a minimum of two major versions when
possible before being removed. For example, if a function takes three arguments,
and that number is reduced to two in major version 10, the three-argument version would
continue to work until, at minimum, major version 12. Past the minimum two-version
threshold, we will attempt to support backwards compatibility beyond two versions
until the maintainers feel the maintenance burden is too high to continue doing so.
### End-of-life
When a release branch reaches the end of its support cycle, the series
will be deprecated in NPM and a final end-of-support release will be
made. This release will add a warning to inform that an unsupported
version of Electron is in use.
These steps are to help app developers learn when a branch they're
using becomes unsupported, but without being excessively intrusive
to end users.
If an application has exceptional circumstances and needs to stay
on an unsupported series of Electron, developers can silence the
end-of-support warning by omitting the final release from the app's
`package.json` `devDependencies`. For example, since the 1-6-x series
ended with an end-of-support 1.6.18 release, developers could choose
to stay in the 1-6-x series without warnings with `devDependency` of
`"electron": 1.6.0 - 1.6.17`.

### 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
25.2.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
I expect that if I set `resizable:false` on a `BrowserWindow`, I won't be able to maximize/fullscreen it.
### Actual Behavior
The green maximize button is enabled and I can maximized. When I click it again however and the window restores to the normal size, then it becomes disabled.
### Testcase Gist URL
https://gist.github.com/pushkin-/67fb41db75da3eb6dbaa34d39d34fabf
### Additional Information
Start the gist, maximize the window, unmaximize it, notice the green maximize button is now correctly disabled.
I also get a bunch of logs in the console when I fullscreen the window for some reason:

[Bug]: Non-resizable windows can still be maximized on Macs the first time
|
### 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
25.2.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
I expect that if I set `resizable:false` on a `BrowserWindow`, I won't be able to maximize/fullscreen it.
### Actual Behavior
The green maximize button is enabled and I can maximized. When I click it again however and the window restores to the normal size, then it becomes disabled.
### Testcase Gist URL
https://gist.github.com/pushkin-/67fb41db75da3eb6dbaa34d39d34fabf
### Additional Information
Start the gist, maximize the window, unmaximize it, notice the green maximize button is now correctly disabled.
I also get a bunch of logs in the console when I fullscreen the window for some reason:

[Bug]: Non-resizable windows can still be maximized on Macs the first time
|
### 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
25.2.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
I expect that if I set `resizable:false` on a `BrowserWindow`, I won't be able to maximize/fullscreen it.
### Actual Behavior
The green maximize button is enabled and I can maximized. When I click it again however and the window restores to the normal size, then it becomes disabled.
### Testcase Gist URL
https://gist.github.com/pushkin-/67fb41db75da3eb6dbaa34d39d34fabf
### Additional Information
Start the gist, maximize the window, unmaximize it, notice the green maximize button is now correctly disabled.
I also get a bunch of logs in the console when I fullscreen the window for some reason:
```

[Bug]: Non-resizable windows can still be maximized on Macs the first time
|
### 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
25.2.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
I expect that if I set `resizable:false` on a `BrowserWindow`, I won't be able to maximize/fullscreen it.
### Actual Behavior
The green maximize button is enabled and I can maximized. When I click it again however and the window restores to the normal size, then it becomes disabled.
### Testcase Gist URL
https://gist.github.com/pushkin-/67fb41db75da3eb6dbaa34d39d34fabf
### Additional Information
Start the gist, maximize the window, unmaximize it, notice the green maximize button is now correctly disabled.
I also get a bunch of logs in the console when I fullscreen the window for some reason:

[Bug]: Child window can't be minimized on Mac when it's brought back by activating the parent window rather than through the minimize section of the dock
|
### 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
25.2.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
I expect to be able to minimize a child window correctly
### Actual Behavior
After the first minimize, if I get the window back by activating the parent window (since I guess the child is brought up since it's supposed to be on top of the parent), I can't minimize/close it.
It needs to be retrieved from the minimize section of the doc
### Testcase Gist URL
https://gist.github.com/pushkin-/c7f43c9692b085adca3a784a390eb89b
### Additional Information
1. start gist
2. click Open Window button
3. minimize the child window (seems to work the first time)
4. then pull it back from the dock (I had to click on some other application and then my app)
5. now the minimize button doesn't do anything. Neither does the X. If I bring the child window back via the minimize section of the dock, then it works fine.
Only happens when the window is a child window.

[Bug]: Child window can't be minimized on Mac when it's brought back by activating the parent window rather than through the minimize section of the dock

### Electron Version
25.2.0
### What operating system are you using?
macOS
### Operating System Version
macOS Ventura 13.2.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
_No response_
### Expected Behavior
I expect to be able to minimize a child window correctly
### Actual Behavior
After the first minimize, if I get the window back by activating the parent window (since I guess the child is brought up since it's supposed to be on top of the parent), I can't minimize/close it.
It needs to be retrieved from the minimize section of the doc
### Testcase Gist URL

### Additional Information
1. start gist
2. click Open Window button
3. minimize the child window (seems to work the first time)
4. then pull it back from the dock (I had to click on some other application and then my app)
5. now the minimize button doesn't do anything. Neither does the X. If I bring the child window back via the minimize section of the dock, then it works fine.
Only happens when the window is a child window.

[Bug]: desktopCapturer fails to generate thumbnails after a PipeWire stream is cancelled externally
|
### 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
25.3.0
### What operating system are you using?
Other Linux
### Operating System Version
Fedora 38
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
1. Get screencast sources using `desktopCapturer.getSources()` on Wayland
2. Select a source on the permission popup
3. Start a screencast stream using `navigator.mediaDevices.getUserMedia()`
4. Interrupt the stream by cancelling screen sharing using OS controls, like on the top bar of GNOME shell
5. Try to fetch screencast sources again using `desktopCapturer.getSources()`, with thumbnails
6. Select a source on the permission popup
7. Sources and thumbnails should be returned by `desktopCapturer.getSources()`
### Actual Behavior
The second call to `desktopCapturer.getSources()` does not complete.
### Testcase Gist URL
https://gist.github.com/aiddya/d368bc2cb7f72a9b030b918ee1332299
### Additional Information
Filing this as a known issue. This issue is not reproducible with Chromium, so it's related to how `DesktopCapturer` and `NativeDesktopMediaList` objects are handled in Electron.

[Bug]: desktopCapturer fails to generate thumbnails after a PipeWire stream is cancelled externally

### Preflight Checklist

### Electron Version
25.3.0
### What operating system are you using?
Other Linux
### Operating System Version
Fedora 38
### What arch are you using?
x64
### Last Known Working Electron version
_No response_
### Expected Behavior
1. Get screencast sources using `desktopCapturer.getSources()` on Wayland
2. Select a source on the permission popup
3. Start a screencast stream using `navigator.mediaDevices.getUserMedia()`
4. Interrupt the stream by cancelling screen sharing using OS controls, like on the top bar of GNOME shell
5. Try to fetch screencast sources again using `desktopCapturer.getSources()`, with thumbnails
6. Select a source on the permission popup
7. Sources and thumbnails should be returned by `desktopCapturer.getSources()`
### Actual Behavior
The second call to `desktopCapturer.getSources()` does not complete.
### Testcase Gist URL
https://gist.github.com/aiddya/d368bc2cb7f72a9b030b918ee1332299
### Additional Information
Filing this as a known issue. This issue is not reproducible with Chromium, so it's related to how `DesktopCapturer` and `NativeDesktopMediaList` objects are handled in Electron.

### Electron Version
25.2.0
### What operating system are you using?
macOS
### Operating System Version
macOS 13.0.1
### What arch are you using?
arm64 (including Apple Silicon)
### Last Known Working Electron version
23.3.8
### Expected Behavior
Second parent window and child window normally show and app continues to work without critical errors.
### Actual Behavior
On `setParentWindow` method the app often crashes with following error:
`Electron exited with signal SIGSEGV.`
### Testcase Gist URL
https://gist.github.com/3b45265f63e8ebfd233665989b81cdab
### Additional Information
Sometimes Electron correctly execute `setParentWindow` method.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Samuel Attard <[email protected]>
Date: Mon, 8 Mar 2021 16:27:39 -0800
Subject: extend ApplyWebPreferences with Electron-specific logic
background_color can be updated at runtime, as such we need to apply the
new background color to the WebView in the ApplyPreferences method.
There is no current way to attach an observer to these prefs so patching
is our only option.
Ideally we could add an embedder observer pattern here but that can be
done in future work.

According to the [API doc](https://www.electronjs.org/docs/latest/api/browser-window#page-visibility), When `backgroundThrottling` is `false, the `document.visibilityState` always return `visible` even if the window is minimized, occluded, or hidden.
> If backgroundThrottling is disabled, the visibility state will remain visible even if the window is minimized, occluded, or hidden.
### Actual Behavior
When `backgroundThrottling` is `false, the `document.visibilityState` always return `hidden` when the window is minimized, occluded, or hidden.

### What operating system are you using?
macOS
### Operating System Version
MacOS 13.4.1
### What arch are you using?

### Actual Behavior
When `backgroundThrottling` is `false, the `document.visibilityState` always return `hidden` when the window is minimized, occluded, or hidden.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Samuel Attard <[email protected]>
Date: Mon, 8 Mar 2021 16:27:39 -0800
Subject: extend ApplyWebPreferences with Electron-specific logic
background_color can be updated at runtime, as such we need to apply the
new background color to the WebView in the ApplyPreferences method.
There is no current way to attach an observer to these prefs so patching
is our only option.
Ideally we could add an embedder observer pattern here but that can be
done in future work.

# desktopCapturer
> Access information about media sources that can be used to capture audio and
> video from the desktop using the [`navigator.mediaDevices.getUserMedia`][] API.
Process: [Main](../glossary.md#main-process)
The following example shows how to capture video from a desktop window whose
title is `Electron`:
```javascript
// In the main process.
const { BrowserWindow, desktopCapturer } = require('electron')
const mainWindow = new BrowserWindow()
desktopCapturer.getSources({ types: ['window', 'screen'] }).then(async sources => {
for (const source of sources) {
if (source.name === 'Electron') {
mainWindow.webContents.send('SET_SOURCE', source.id)
return
}
}
})
```
```javascript @ts-nocheck
// In the preload script.
const { ipcRenderer } = require('electron')
ipcRenderer.on('SET_SOURCE', async (event, sourceId) => {
try {
const stream = await navigator.mediaDevices.getUserMedia({
audio: false,
video: {
mandatory: {
chromeMediaSource: 'desktop',
chromeMediaSourceId: sourceId,
minWidth: 1280,
maxWidth: 1280,
minHeight: 720,
maxHeight: 720
}
}
})
handleStream(stream)
} catch (e) {
handleError(e)
}
})
function handleStream (stream) {
const video = document.querySelector('video')
video.srcObject = stream
video.onloadedmetadata = (e) => video.play()
}
function handleError (e) {
console.log(e)
}
```
To capture video from a source provided by `desktopCapturer` the constraints
passed to [`navigator.mediaDevices.getUserMedia`][] must include
`chromeMediaSource: 'desktop'`, and `audio: false`.
To capture both audio and video from the entire desktop the constraints passed
to [`navigator.mediaDevices.getUserMedia`][] must include `chromeMediaSource: 'desktop'`,
for both `audio` and `video`, but should not include a `chromeMediaSourceId` constraint.
```javascript
const constraints = {
audio: {
mandatory: {
chromeMediaSource: 'desktop'
}
},
video: {
mandatory: {
chromeMediaSource: 'desktop'
}
}
}
```
## Methods
The `desktopCapturer` module has the following methods:
### `desktopCapturer.getSources(options)`
* `options` Object
* `types` string[] - An array of strings that lists the types of desktop sources
to be captured, available types are `screen` and `window`.
* `thumbnailSize` [Size](structures/size.md) (optional) - The size that the media source thumbnail
should be scaled to. Default is `150` x `150`. Set width or height to 0 when you do not need
the thumbnails. This will save the processing time required for capturing the content of each
window and screen.
* `fetchWindowIcons` boolean (optional) - Set to true to enable fetching window icons. The default
value is false. When false the appIcon property of the sources return null. Same if a source has
the type screen.
Returns `Promise<DesktopCapturerSource[]>` - Resolves with an array of [`DesktopCapturerSource`](structures/desktop-capturer-source.md) objects, each `DesktopCapturerSource` represents a screen or an individual window that can be captured.
**Note** Capturing the screen contents requires user consent on macOS 10.15 Catalina or higher,
which can detected by [`systemPreferences.getMediaAccessStatus`][].
[`navigator.mediaDevices.getUserMedia`]: https://developer.mozilla.org/en/docs/Web/API/MediaDevices/getUserMedia
[`systemPreferences.getMediaAccessStatus`]: system-preferences.md#systempreferencesgetmediaaccessstatusmediatype-windows-macos
## Caveats
`navigator.mediaDevices.getUserMedia` does not work on macOS for audio capture due to a fundamental limitation whereby apps that want to access the system's audio require a [signed kernel extension](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/KernelExtensions/KernelExtensions.html). Chromium, and by extension Electron, does not provide this.
It is possible to circumvent this limitation by capturing system audio with another macOS app like Soundflower and passing it through a virtual audio input device. This virtual device can then be queried with `navigator.mediaDevices.getUserMedia`.

# nativeImage
> Create tray, dock, and application icons using PNG or JPG files.
Process: [Main](../glossary.md#main-process), [Renderer](../glossary.md#renderer-process)
In Electron, for the APIs that take images, you can pass either file paths or
`NativeImage` instances. An empty image will be used when `null` is passed.
For example, when creating a tray or setting a window's icon, you can pass an
image file path as a `string`:
```javascript
const { BrowserWindow, Tray } = require('electron')
const appIcon = new Tray('/Users/somebody/images/icon.png')
const win = new BrowserWindow({ icon: '/Users/somebody/images/window.png' })
console.log(appIcon, win)
```
Or read the image from the clipboard, which returns a `NativeImage`:
```javascript
const { clipboard, Tray } = require('electron')
const image = clipboard.readImage()
const appIcon = new Tray(image)
console.log(appIcon)
```
## Supported Formats
Currently `PNG` and `JPEG` image formats are supported. `PNG` is recommended
because of its support for transparency and lossless compression.
On Windows, you can also load `ICO` icons from file paths. For best visual
quality, it is recommended to include at least the following sizes in the:
* Small icon
* 16x16 (100% DPI scale)
* 20x20 (125% DPI scale)
* 24x24 (150% DPI scale)
* 32x32 (200% DPI scale)
* Large icon
* 32x32 (100% DPI scale)
* 40x40 (125% DPI scale)
* 48x48 (150% DPI scale)
* 64x64 (200% DPI scale)
* 256x256
Check the _Size requirements_ section in [this article][icons].
[icons]: https://learn.microsoft.com/en-us/windows/win32/uxguide/vis-icons
## High Resolution Image
On platforms that have high-DPI support such as Apple Retina displays, you can
append `@2x` after image's base filename to mark it as a high resolution image.
For example, if `icon.png` is a normal image that has standard resolution, then
`[email protected]` will be treated as a high resolution image that has double DPI
density.
If you want to support displays with different DPI densities at the same time,
you can put images with different sizes in the same folder and use the filename
without DPI suffixes. For example:
```plaintext
images/
├── icon.png
├── [email protected]
└── [email protected]
```
```javascript
const { Tray } = require('electron')
const appIcon = new Tray('/Users/somebody/images/icon.png')
console.log(appIcon)
```
The following suffixes for DPI are also supported:
* `@1x`
* `@1.25x`
* `@1.33x`
* `@1.4x`
* `@1.5x`
* `@1.8x`
* `@2x`
* `@2.5x`
* `@3x`
* `@4x`
* `@5x`
## Template Image
Template images consist of black and an alpha channel.
Template images are not intended to be used as standalone images and are usually
mixed with other content to create the desired final appearance.
The most common case is to use template images for a menu bar icon, so it can
adapt to both light and dark menu bars.
**Note:** Template image is only supported on macOS.
To mark an image as a template image, its filename should end with the word
`Template`. For example:
* `xxxTemplate.png`

The `nativeImage` module has the following methods, all of which return
an instance of the `NativeImage` class:
### `nativeImage.createEmpty()`
Returns `NativeImage`
Creates an empty `NativeImage` instance.
### `nativeImage.createThumbnailFromPath(path, size)` _macOS_ _Windows_
* `path` string - path to a file that we intend to construct a thumbnail out of.
* `size` [Size](structures/size.md) - the desired width and height (positive numbers) of the thumbnail.
Returns `Promise<NativeImage>` - fulfilled with the file's thumbnail preview image, which is a [NativeImage](native-image.md).
Note: The Windows implementation will ignore `size.height` and scale the height according to `size.width`.
### `nativeImage.createFromPath(path)`
* `path` string
Returns `NativeImage`
Creates a new `NativeImage` instance from a file located at `path`. This method
returns an empty image if the `path` does not exist, cannot be read, or is not
a valid image.
```javascript
const nativeImage = require('electron').nativeImage
const image = nativeImage.createFromPath('/Users/somebody/images/icon.png')
console.log(image)
```
### `nativeImage.createFromBitmap(buffer, options)`
* `buffer` [Buffer][buffer]
* `options` Object
* `width` Integer
* `height` Integer
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `NativeImage`
Creates a new `NativeImage` instance from `buffer` that contains the raw bitmap
pixel data returned by `toBitmap()`. The specific format is platform-dependent.
### `nativeImage.createFromBuffer(buffer[, options])`
* `buffer` [Buffer][buffer]
* `options` Object (optional)
* `width` Integer (optional) - Required for bitmap buffers.
* `height` Integer (optional) - Required for bitmap buffers.
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `NativeImage`
Creates a new `NativeImage` instance from `buffer`. Tries to decode as PNG or JPEG first.
### `nativeImage.createFromDataURL(dataURL)`
* `dataURL` string
Returns `NativeImage`
Creates a new `NativeImage` instance from `dataURL`.
### `nativeImage.createFromNamedImage(imageName[, hslShift])` _macOS_
* `imageName` string
* `hslShift` number[] (optional)
Returns `NativeImage`
Creates a new `NativeImage` instance from the NSImage that maps to the
given image name. See [`System Icons`](https://developer.apple.com/design/human-interface-guidelines/macos/icons-and-images/system-icons/)
for a list of possible values.
The `hslShift` is applied to the image with the following rules:
* `hsl_shift[0]` (hue): The absolute hue value for the image - 0 and 1 map
to 0 and 360 on the hue color wheel (red).
* `hsl_shift[1]` (saturation): A saturation shift for the image, with the
following key values:
0 = remove all color.
0.5 = leave unchanged.
1 = fully saturate the image.
* `hsl_shift[2]` (lightness): A lightness shift for the image, with the
following key values:
0 = remove all lightness (make all pixels black).
0.5 = leave unchanged.
1 = full lightness (make all pixels white).
This means that `[-1, 0, 1]` will make the image completely white and
`[-1, 1, 0]` will make the image completely black.
In some cases, the `NSImageName` doesn't match its string representation; one example of this is `NSFolderImageName`, whose string representation would actually be `NSFolder`. Therefore, you'll need to determine the correct string representation for your image before passing it in. This can be done with the following:
`echo -e '#import <Cocoa/Cocoa.h>\nint main() { NSLog(@"%@", SYSTEM_IMAGE_NAME); }' | clang -otest -x objective-c -framework Cocoa - && ./test`
where `SYSTEM_IMAGE_NAME` should be replaced with any value from [this list](https://developer.apple.com/documentation/appkit/nsimagename?language=objc).
## Class: NativeImage
> Natively wrap images such as tray, dock, and application icons.
Process: [Main](../glossary.md#main-process), [Renderer](../glossary.md#renderer-process)<br />
_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
### Instance Methods
The following methods are available on instances of the `NativeImage` class:
#### `image.toPNG([options])`
* `options` Object (optional)
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `Buffer` - A [Buffer][buffer] that contains the image's `PNG` encoded data.
#### `image.toJPEG(quality)`
* `quality` Integer - Between 0 - 100.
Returns `Buffer` - A [Buffer][buffer] that contains the image's `JPEG` encoded data.
#### `image.toBitmap([options])`
* `options` Object (optional)
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `Buffer` - A [Buffer][buffer] that contains a copy of the image's raw bitmap pixel
data.
#### `image.toDataURL([options])`
* `options` Object (optional)
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `string` - The data URL of the image.
#### `image.getBitmap([options])`
* `options` Object (optional)
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `Buffer` - A [Buffer][buffer] that contains the image's raw bitmap pixel data.
The difference between `getBitmap()` and `toBitmap()` is that `getBitmap()` does not
copy the bitmap data, so you have to use the returned Buffer immediately in
current event loop tick; otherwise the data might be changed or destroyed.
#### `image.getNativeHandle()` _macOS_
Returns `Buffer` - A [Buffer][buffer] that stores C pointer to underlying native handle of
the image. On macOS, a pointer to `NSImage` instance would be returned.
Notice that the returned pointer is a weak pointer to the underlying native
image instead of a copy, so you _must_ ensure that the associated
`nativeImage` instance is kept around.
#### `image.isEmpty()`
Returns `boolean` - Whether the image is empty.
#### `image.getSize([scaleFactor])`
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns [`Size`](structures/size.md).
If `scaleFactor` is passed, this will return the size corresponding to the image representation most closely matching the passed value.
#### `image.setTemplateImage(option)`
* `option` boolean
Marks the image as a template image.
#### `image.isTemplateImage()`
Returns `boolean` - Whether the image is a template image.
#### `image.crop(rect)`
* `rect` [Rectangle](structures/rectangle.md) - The area of the image to crop.
Returns `NativeImage` - The cropped image.
#### `image.resize(options)`
* `options` Object
* `width` Integer (optional) - Defaults to the image's width.
* `height` Integer (optional) - Defaults to the image's height.
* `quality` string (optional) - The desired quality of the resize image.
Possible values are `good`, `better`, or `best`. The default is `best`.
These values express a desired quality/speed tradeoff. They are translated
into an algorithm-specific method that depends on the capabilities
(CPU, GPU) of the underlying platform. It is possible for all three methods
to be mapped to the same algorithm on a given platform.
Returns `NativeImage` - The resized image.
If only the `height` or the `width` are specified then the current aspect ratio
will be preserved in the resized image.
#### `image.getAspectRatio([scaleFactor])`
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `Number` - The image's aspect ratio.
If `scaleFactor` is passed, this will return the aspect ratio corresponding to the image representation most closely matching the passed value.
#### `image.getScaleFactors()`
Returns `Number[]` - An array of all scale factors corresponding to representations for a given nativeImage.
#### `image.addRepresentation(options)`
* `options` Object
* `scaleFactor` Number (optional) - The scale factor to add the image representation for.
* `width` Integer (optional) - Defaults to 0. Required if a bitmap buffer
is specified as `buffer`.
* `height` Integer (optional) - Defaults to 0. Required if a bitmap buffer
is specified as `buffer`.
* `buffer` Buffer (optional) - The buffer containing the raw image data.
* `dataURL` string (optional) - The data URL containing either a base 64
encoded PNG or JPEG image.
Add an image representation for a specific scale factor. This can be used
to explicitly add different scale factor representations to an image. This
can be called on empty images.
[buffer]: https://nodejs.org/api/buffer.html#buffer_class_buffer
### Instance Properties
#### `nativeImage.isMacTemplateImage` _macOS_
A `boolean` property that determines whether the image is considered a [template image](https://developer.apple.com/documentation/appkit/nsimage/1520017-template).
Please note that this property only has an effect on macOS.

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

# session
> Manage browser sessions, cookies, cache, proxy settings, etc.
Process: [Main](../glossary.md#main-process)
The `session` module can be used to create new `Session` objects.
You can also access the `session` of existing pages by using the `session`
property of [`WebContents`](web-contents.md), or from the `session` module.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.loadURL('http://github.com')
const ses = win.webContents.session
console.log(ses.getUserAgent())
```
## Methods
The `session` module has the following methods:
### `session.fromPartition(partition[, options])`
* `partition` string
* `options` Object (optional)
* `cache` boolean - Whether to enable cache.
Returns `Session` - A session instance from `partition` string. When there is an existing
`Session` with the same `partition`, it will be returned; otherwise a new
`Session` instance will be created with `options`.
If `partition` starts with `persist:`, the page will use a persistent session
available to all pages in the app with the same `partition`. if there is no
`persist:` prefix, the page will use an in-memory session. If the `partition` is
empty then default session of the app will be returned.
To create a `Session` with `options`, you have to ensure the `Session` with the
`partition` has never been used before. There is no way to change the `options`
of an existing `Session` object.
### `session.fromPath(path[, options])`
* `path` string
* `options` Object (optional)
* `cache` boolean - Whether to enable cache.
Returns `Session` - A session instance from the absolute path as specified by the `path`
string. When there is an existing `Session` with the same absolute path, it
will be returned; otherwise a new `Session` instance will be created with `options`. The
call will throw an error if the path is not an absolute path. Additionally, an error will
be thrown if an empty string is provided.
To create a `Session` with `options`, you have to ensure the `Session` with the
`path` has never been used before. There is no way to change the `options`
of an existing `Session` object.
## Properties
The `session` module has the following properties:
### `session.defaultSession`
A `Session` object, the default session object of the app.
## Class: Session
> Get and set properties of a session.
Process: [Main](../glossary.md#main-process)<br />
_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
You can create a `Session` object in the `session` module:
```javascript
const { session } = require('electron')
const ses = session.fromPartition('persist:name')
console.log(ses.getUserAgent())
```

* `item` [DownloadItem](download-item.md)
* `webContents` [WebContents](web-contents.md)
Emitted when Electron is about to download `item` in `webContents`.
Calling `event.preventDefault()` will cancel the download and `item` will not be
available from next tick of the process.
```javascript @ts-expect-error=[4]
const { session } = require('electron')
session.defaultSession.on('will-download', (event, item, webContents) => {

Emitted when a HID device needs to be selected when a call to
`navigator.hid.requestDevice` is made. `callback` should be called with
`deviceId` to be selected; passing no arguments to `callback` will
cancel the request. Additionally, permissioning on `navigator.hid` can
be further managed by using [`ses.setPermissionCheckHandler(handler)`](#sessetpermissioncheckhandlerhandler)
and [`ses.setDevicePermissionHandler(handler)`](#sessetdevicepermissionhandlerhandler).
```javascript @ts-type={fetchGrantedDevices:()=>(Array<Electron.DevicePermissionHandlerHandlerDetails['device']>)}
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow()

if (permission === 'hid') {
// Add logic here to determine if permission should be given to allow HID selection
return true
}
return false
})
// Optionally, retrieve previously persisted devices from a persistent store
const grantedDevices = fetchGrantedDevices()
win.webContents.session.setDevicePermissionHandler((details) => {
if (new URL(details.origin).hostname === 'some-host' && details.deviceType === 'hid') {
if (details.device.vendorId === 123 && details.device.productId === 345) {

return grantedDevices.some((grantedDevice) => {
return grantedDevice.vendorId === details.device.vendorId &&
grantedDevice.productId === details.device.productId &&
grantedDevice.serialNumber && grantedDevice.serialNumber === details.device.serialNumber
})
}
return false
})
win.webContents.session.on('select-hid-device', (event, details, callback) => {
event.preventDefault()

Returns:
* `event` Event
* `details` Object
* `device` [HIDDevice[]](structures/hid-device.md)
* `frame` [WebFrameMain](web-frame-main.md)
Emitted after `navigator.hid.requestDevice` has been called and
`select-hid-device` has fired if a new device becomes available before
the callback from `select-hid-device` is called. This event is intended for
use when using a UI to ask users to pick a device so that the UI can be updated
with the newly added device.
#### Event: 'hid-device-removed'
Returns:
* `event` Event
* `details` Object
* `device` [HIDDevice[]](structures/hid-device.md)
* `frame` [WebFrameMain](web-frame-main.md)

Returns:
* `event` Event
* `portList` [SerialPort[]](structures/serial-port.md)
* `webContents` [WebContents](web-contents.md)
* `callback` Function
* `portId` string
Emitted when a serial port needs to be selected when a call to
`navigator.serial.requestPort` is made. `callback` should be called with
`portId` to be selected, passing an empty string to `callback` will
cancel the request. Additionally, permissioning on `navigator.serial` can
be managed by using [ses.setPermissionCheckHandler(handler)](#sessetpermissioncheckhandlerhandler)
with the `serial` permission.
```javascript @ts-type={fetchGrantedDevices:()=>(Array<Electron.DevicePermissionHandlerHandlerDetails['device']>)}
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow({

#### Event: 'select-usb-device'
Returns:
* `event` Event
* `details` Object
* `deviceList` [USBDevice[]](structures/usb-device.md)
* `frame` [WebFrameMain](web-frame-main.md)
* `callback` Function
* `deviceId` string (optional)
Emitted when a USB device needs to be selected when a call to
`navigator.usb.requestDevice` is made. `callback` should be called with
`deviceId` to be selected; passing no arguments to `callback` will
cancel the request. Additionally, permissioning on `navigator.usb` can
be further managed by using [`ses.setPermissionCheckHandler(handler)`](#sessetpermissioncheckhandlerhandler)
and [`ses.setDevicePermissionHandler(handler)`](#sessetdevicepermissionhandlerhandler).

`select-usb-device` has fired if a new device becomes available before
the callback from `select-usb-device` is called. This event is intended for
use when using a UI to ask users to pick a device so that the UI can be updated
with the newly added device.
#### Event: 'usb-device-removed'
Returns:
* `event` Event
* `device` [USBDevice](structures/usb-device.md)
* `webContents` [WebContents](web-contents.md)
Emitted after `navigator.usb.requestDevice` has been called and
`select-usb-device` has fired if a device has been removed before the callback
from `select-usb-device` is called. This event is intended for use when using
a UI to ask users to pick a device so that the UI can be updated to remove the
specified device.
#### Event: 'usb-device-revoked'
Returns:
* `event` Event
* `details` Object
* `device` [USBDevice](structures/usb-device.md)
* `origin` string (optional) - The origin that the device has been revoked from.
Emitted after `USBDevice.forget()` has been called. This event can be used
to help maintain persistent storage of permissions when
`setDevicePermissionHandler` is used.
### Instance Methods
The following methods are available on instances of `Session`:
#### `ses.getCacheSize()`
Returns `Promise<Integer>` - the session's current cache size, in bytes.
#### `ses.clearCache()`
Returns `Promise<void>` - resolves when the cache clear operation is complete.
Clears the session’s HTTP cache.
#### `ses.clearStorageData([options])`
* `options` Object (optional)
* `origin` string (optional) - Should follow `window.location.origin`’s representation
`scheme://host:port`.
* `storages` string[] (optional) - The types of storages to clear, can contain:
`cookies`, `filesystem`, `indexdb`, `localstorage`,
`shadercache`, `websql`, `serviceworkers`, `cachestorage`. If not
specified, clear all storage types.
* `quotas` string[] (optional) - The types of quotas to clear, can contain:
`temporary`, `syncable`. If not specified, clear all quotas.
Returns `Promise<void>` - resolves when the storage data has been cleared.
#### `ses.flushStorageData()`
Writes any unwritten DOMStorage data to disk.
#### `ses.setProxy(config)`
* `config` Object
* `mode` string (optional) - The proxy mode. Should be one of `direct`,
`auto_detect`, `pac_script`, `fixed_servers` or `system`. If it's
unspecified, it will be automatically determined based on other specified
options.
* `direct`
In direct mode all connections are created directly, without any proxy involved.
* `auto_detect`
In auto_detect mode the proxy configuration is determined by a PAC script that can
be downloaded at http://wpad/wpad.dat.
* `pac_script`
In pac_script mode the proxy configuration is determined by a PAC script that is
retrieved from the URL specified in the `pacScript`. This is the default mode
if `pacScript` is specified.
* `fixed_servers`
In fixed_servers mode the proxy configuration is specified in `proxyRules`.
This is the default mode if `proxyRules` is specified.
* `system`
In system mode the proxy configuration is taken from the operating system.
Note that the system mode is different from setting no proxy configuration.
In the latter case, Electron falls back to the system settings
only if no command-line options influence the proxy configuration.
* `pacScript` string (optional) - The URL associated with the PAC file.
* `proxyRules` string (optional) - Rules indicating which proxies to use.
* `proxyBypassRules` string (optional) - Rules indicating which URLs should
bypass the proxy settings.
Returns `Promise<void>` - Resolves when the proxy setting process is complete.
Sets the proxy settings.
When `mode` is unspecified, `pacScript` and `proxyRules` are provided together, the `proxyRules`
option is ignored and `pacScript` configuration is applied.
You may need `ses.closeAllConnections` to close currently in flight connections to prevent
pooled sockets using previous proxy from being reused by future requests.
The `proxyRules` has to follow the rules below:
```sh
proxyRules = schemeProxies[";"<schemeProxies>]
schemeProxies = [<urlScheme>"="]<proxyURIList>
urlScheme = "http" | "https" | "ftp" | "socks"
proxyURIList = <proxyURL>[","<proxyURIList>]
proxyURL = [<proxyScheme>"://"]<proxyHost>[":"<proxyPort>]
```
For example:
* `http=foopy:80;ftp=foopy2` - Use HTTP proxy `foopy:80` for `http://` URLs, and
HTTP proxy `foopy2:80` for `ftp://` URLs.
* `foopy:80` - Use HTTP proxy `foopy:80` for all URLs.
* `foopy:80,bar,direct://` - Use HTTP proxy `foopy:80` for all URLs, failing
over to `bar` if `foopy:80` is unavailable, and after that using no proxy.
* `socks4://foopy` - Use SOCKS v4 proxy `foopy:1080` for all URLs.
* `http=foopy,socks5://bar.com` - Use HTTP proxy `foopy` for http URLs, and fail
over to the SOCKS5 proxy `bar.com` if `foopy` is unavailable.
* `http=foopy,direct://` - Use HTTP proxy `foopy` for http URLs, and use no
proxy if `foopy` is unavailable.
* `http=foopy;socks=foopy2` - Use HTTP proxy `foopy` for http URLs, and use
`socks4://foopy2` for all other URLs.
The `proxyBypassRules` is a comma separated list of rules described below:
* `[ URL_SCHEME "://" ] HOSTNAME_PATTERN [ ":" <port> ]`
Match all hostnames that match the pattern HOSTNAME_PATTERN.
Examples:
"foobar.com", "\*foobar.com", "\*.foobar.com", "\*foobar.com:99",
"https://x.\*.y.com:99"
* `"." HOSTNAME_SUFFIX_PATTERN [ ":" PORT ]`
Match a particular domain suffix.
Examples:
".google.com", ".com", "http://.google.com"
* `[ SCHEME "://" ] IP_LITERAL [ ":" PORT ]`
Match URLs which are IP address literals.
Examples:
"127.0.1", "\[0:0::1]", "\[::1]", "http://\[::1]:99"
* `IP_LITERAL "/" PREFIX_LENGTH_IN_BITS`
Match any URL that is to an IP literal that falls between the
given range. IP range is specified using CIDR notation.
Examples:
"192.168.1.1/16", "fefe:13::abc/33".
* `<local>`
Match local addresses. The meaning of `<local>` is whether the
host matches one of: "127.0.0.1", "::1", "localhost".
#### `ses.resolveHost(host, [options])`
* `host` string - Hostname to resolve.
* `options` Object (optional)
* `queryType` string (optional) - Requested DNS query type. If unspecified,
resolver will pick A or AAAA (or both) based on IPv4/IPv6 settings:
* `A` - Fetch only A records
* `AAAA` - Fetch only AAAA records.
* `source` string (optional) - The source to use for resolved addresses.
Default allows the resolver to pick an appropriate source. Only affects use
of big external sources (e.g. calling the system for resolution or using
DNS). Even if a source is specified, results can still come from cache,
resolving "localhost" or IP literals, etc. One of the following values:
* `any` (default) - Resolver will pick an appropriate source. Results could
come from DNS, MulticastDNS, HOSTS file, etc
* `system` - Results will only be retrieved from the system or OS, e.g. via
the `getaddrinfo()` system call
* `dns` - Results will only come from DNS queries
* `mdns` - Results will only come from Multicast DNS queries
* `localOnly` - No external sources will be used. Results will only come
from fast local sources that are available no matter the source setting,
e.g. cache, hosts file, IP literal resolution, etc.
* `cacheUsage` string (optional) - Indicates what DNS cache entries, if any,
can be used to provide a response. One of the following values:
* `allowed` (default) - Results may come from the host cache if non-stale
* `staleAllowed` - Results may come from the host cache even if stale (by
expiration or network changes)
* `disallowed` - Results will not come from the host cache.
* `secureDnsPolicy` string (optional) - Controls the resolver's Secure DNS
behavior for this request. One of the following values:
* `allow` (default)
* `disable`
Returns [`Promise<ResolvedHost>`](structures/resolved-host.md) - Resolves with the resolved IP addresses for the `host`.
#### `ses.resolveProxy(url)`
* `url` URL
Returns `Promise<string>` - Resolves with the proxy information for `url`.
#### `ses.forceReloadProxyConfig()`
Returns `Promise<void>` - Resolves when the all internal states of proxy service is reset and the latest proxy configuration is reapplied if it's already available. The pac script will be fetched from `pacScript` again if the proxy mode is `pac_script`.
#### `ses.setDownloadPath(path)`
* `path` string - The download location.
Sets download saving directory. By default, the download directory will be the
`Downloads` under the respective app folder.
#### `ses.enableNetworkEmulation(options)`
* `options` Object
* `offline` boolean (optional) - Whether to emulate network outage. Defaults
to false.
* `latency` Double (optional) - RTT in ms. Defaults to 0 which will disable
latency throttling.
* `downloadThroughput` Double (optional) - Download rate in Bps. Defaults to 0
which will disable download throttling.
* `uploadThroughput` Double (optional) - Upload rate in Bps. Defaults to 0
which will disable upload throttling.
Emulates network with the given configuration for the `session`.
```javascript
const win = new BrowserWindow()
// To emulate a GPRS connection with 50kbps throughput and 500 ms latency.
win.webContents.session.enableNetworkEmulation({
latency: 500,
downloadThroughput: 6400,
uploadThroughput: 6400
})
// To emulate a network outage.
win.webContents.session.enableNetworkEmulation({ offline: true })
```
#### `ses.preconnect(options)`
* `options` Object
* `url` string - URL for preconnect. Only the origin is relevant for opening the socket.
* `numSockets` number (optional) - number of sockets to preconnect. Must be between 1 and 6. Defaults to 1.
Preconnects the given number of sockets to an origin.
#### `ses.closeAllConnections()`
Returns `Promise<void>` - Resolves when all connections are closed.
**Note:** It will terminate / fail all requests currently in flight.
#### `ses.fetch(input[, init])`
* `input` string | [GlobalRequest](https://nodejs.org/api/globals.html#request)
* `init` [RequestInit](https://developer.mozilla.org/en-US/docs/Web/API/fetch#options) (optional)
Returns `Promise<GlobalResponse>` - see [Response](https://developer.mozilla.org/en-US/docs/Web/API/Response).
Sends a request, similarly to how `fetch()` works in the renderer, using
Chrome's network stack. This differs from Node's `fetch()`, which uses
Node.js's HTTP stack.
Example:
```js
async function example () {
const response = await net.fetch('https://my.app')
if (response.ok) {
const body = await response.json()
// ... use the result.
}
}
```
See also [`net.fetch()`](net.md#netfetchinput-init), a convenience method which
issues requests from the [default session](#sessiondefaultsession).
See the MDN documentation for
[`fetch()`](https://developer.mozilla.org/en-US/docs/Web/API/fetch) for more
details.
Limitations:
* `net.fetch()` does not support the `data:` or `blob:` schemes.
* The value of the `integrity` option is ignored.
* The `.type` and `.url` values of the returned `Response` object are
incorrect.
By default, requests made with `net.fetch` can be made to [custom
protocols](protocol.md) as well as `file:`, and will trigger
[webRequest](web-request.md) handlers if present. When the non-standard
`bypassCustomProtocolHandlers` option is set in RequestInit, custom protocol
handlers will not be called for this request. This allows forwarding an
intercepted request to the built-in handler. [webRequest](web-request.md)
handlers will still be triggered when bypassing custom protocols.
```js
protocol.handle('https', (req) => {
if (req.url === 'https://my-app.com') {
return new Response('<body>my app</body>')
} else {
return net.fetch(req, { bypassCustomProtocolHandlers: true })
}
})
```
#### `ses.disableNetworkEmulation()`
Disables any network emulation already active for the `session`. Resets to
the original network configuration.
#### `ses.setCertificateVerifyProc(proc)`
* `proc` Function | null
* `request` Object
* `hostname` string
* `certificate` [Certificate](structures/certificate.md)
* `validatedCertificate` [Certificate](structures/certificate.md)
* `isIssuedByKnownRoot` boolean - `true` if Chromium recognises the root CA as a standard root. If it isn't then it's probably the case that this certificate was generated by a MITM proxy whose root has been installed locally (for example, by a corporate proxy). This should not be trusted if the `verificationResult` is not `OK`.
* `verificationResult` string - `OK` if the certificate is trusted, otherwise an error like `CERT_REVOKED`.
* `errorCode` Integer - Error code.
* `callback` Function
* `verificationResult` Integer - Value can be one of certificate error codes
from [here](https://source.chromium.org/chromium/chromium/src/+/main:net/base/net_error_list.h).
Apart from the certificate error codes, the following special codes can be used.
* `0` - Indicates success and disables Certificate Transparency verification.
* `-2` - Indicates failure.
* `-3` - Uses the verification result from chromium.
Sets the certificate verify proc for `session`, the `proc` will be called with
`proc(request, callback)` whenever a server certificate
verification is requested. Calling `callback(0)` accepts the certificate,
calling `callback(-2)` rejects it.
Calling `setCertificateVerifyProc(null)` will revert back to default certificate
verify proc.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.webContents.session.setCertificateVerifyProc((request, callback) => {
const { hostname } = request
if (hostname === 'github.com') {
callback(0)
} else {
callback(-2)
}
})
```
> **NOTE:** The result of this procedure is cached by the network service.

Sets the handler which can be used to respond to permission requests for the `session`.
Calling `callback(true)` will allow the permission and `callback(false)` will reject it.
To clear the handler, call `setPermissionRequestHandler(null)`. Please note that
you must also implement `setPermissionCheckHandler` to get complete permission handling.
Most web APIs do a permission check and then make a permission request if the check is denied.
```javascript
const { session } = require('electron')
session.fromPartition('some-partition').setPermissionRequestHandler((webContents, permission, callback) => {
if (webContents.getURL() === 'some-host' && permission === 'notifications') {
return callback(false) // denied.
}
callback(true)
})
```
#### `ses.setPermissionCheckHandler(handler)`
* `handler` Function\<boolean> | null
* `webContents` ([WebContents](web-contents.md) | null) - WebContents checking the permission. Please note that if the request comes from a subframe you should use `requestingUrl` to check the request origin. All cross origin sub frames making permission checks will pass a `null` webContents to this handler, while certain other permission checks such as `notifications` checks will always pass `null`. You should use `embeddingOrigin` and `requestingOrigin` to determine what origin the owning frame and the requesting frame are on respectively.

* `serial` - Read from and write to serial devices with the [Web Serial API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Serial_API).
* `usb` - Expose non-standard Universal Serial Bus (USB) compatible devices services to the web with the [WebUSB API](https://developer.mozilla.org/en-US/docs/Web/API/WebUSB_API).
* `requestingOrigin` string - The origin URL of the permission check
* `details` Object - Some properties are only available on certain permission types.
* `embeddingOrigin` string (optional) - The origin of the frame embedding the frame that made the permission check. Only set for cross-origin sub frames making permission checks.
* `securityOrigin` string (optional) - The security origin of the `media` check.
* `mediaType` string (optional) - The type of media access being requested, can be `video`,
`audio` or `unknown`
* `requestingUrl` string (optional) - The last URL the requesting frame loaded. This is not provided for cross-origin sub frames making permission checks.
* `isMainFrame` boolean - Whether the frame making the request is the main frame
Sets the handler which can be used to respond to permission checks for the `session`.
Returning `true` will allow the permission and `false` will reject it. Please note that
you must also implement `setPermissionRequestHandler` to get complete permission handling.
Most web APIs do a permission check and then make a permission request if the check is denied.
To clear the handler, call `setPermissionCheckHandler(null)`.
```javascript
const { session } = require('electron')
const url = require('url')
session.fromPartition('some-partition').setPermissionCheckHandler((webContents, permission, requestingOrigin) => {
if (new URL(requestingOrigin).hostname === 'some-host' && permission === 'notifications') {
return true // granted
}
return false // denied
})
```
#### `ses.setDisplayMediaRequestHandler(handler)`
* `handler` Function | null
* `request` Object
* `frame` [WebFrameMain](web-frame-main.md) - Frame that is requesting access to media.
* `securityOrigin` String - Origin of the page making the request.
* `videoRequested` Boolean - true if the web content requested a video stream.
* `audioRequested` Boolean - true if the web content requested an audio stream.
* `userGesture` Boolean - Whether a user gesture was active when this request was triggered.
* `callback` Function
* `streams` Object
* `video` Object | [WebFrameMain](web-frame-main.md) (optional)
* `id` String - The id of the stream being granted. This will usually
come from a [DesktopCapturerSource](structures/desktop-capturer-source.md)
object.
* `name` String - The name of the stream being granted. This will
usually come from a [DesktopCapturerSource](structures/desktop-capturer-source.md)
object.
* `audio` String | [WebFrameMain](web-frame-main.md) (optional) - If
a string is specified, can be `loopback` or `loopbackWithMute`.
Specifying a loopback device will capture system audio, and is
currently only supported on Windows. If a WebFrameMain is specified,
will capture audio from that frame.
* `enableLocalEcho` Boolean (optional) - If `audio` is a [WebFrameMain](web-frame-main.md)
and this is set to `true`, then local playback of audio will not be muted (e.g. using `MediaRecorder`
to record `WebFrameMain` with this flag set to `true` will allow audio to pass through to the speakers
while recording). Default is `false`.
This handler will be called when web content requests access to display media
via the `navigator.mediaDevices.getDisplayMedia` API. Use the
[desktopCapturer](desktop-capturer.md) API to choose which stream(s) to grant
access to.
```javascript
const { session, desktopCapturer } = require('electron')
session.defaultSession.setDisplayMediaRequestHandler((request, callback) => {
desktopCapturer.getSources({ types: ['screen'] }).then((sources) => {
// Grant access to the first screen found.
callback({ video: sources[0] })
})
})
```
Passing a [WebFrameMain](web-frame-main.md) object as a video or audio stream
will capture the video or audio stream from that frame.
```javascript
const { session } = require('electron')
session.defaultSession.setDisplayMediaRequestHandler((request, callback) => {
// Allow the tab to capture itself.
callback({ video: request.frame })
})
```
Passing `null` instead of a function resets the handler to its default state.
#### `ses.setDevicePermissionHandler(handler)`
* `handler` Function\<boolean> | null
* `details` Object
* `deviceType` string - The type of device that permission is being requested on, can be `hid`, `serial`, or `usb`.
* `origin` string - The origin URL of the device permission check.
* `device` [HIDDevice](structures/hid-device.md) | [SerialPort](structures/serial-port.md) | [USBDevice](structures/usb-device.md) - the device that permission is being requested for.
Sets the handler which can be used to respond to device permission checks for the `session`.
Returning `true` will allow the device to be permitted and `false` will reject it.
To clear the handler, call `setDevicePermissionHandler(null)`.
This handler can be used to provide default permissioning to devices without first calling for permission
to devices (eg via `navigator.hid.requestDevice`). If this handler is not defined, the default device
permissions as granted through device selection (eg via `navigator.hid.requestDevice`) will be used.
Additionally, the default behavior of Electron is to store granted device permision in memory.
If longer term storage is needed, a developer can store granted device
permissions (eg when handling the `select-hid-device` event) and then read from that storage with `setDevicePermissionHandler`.
```javascript @ts-type={fetchGrantedDevices:()=>(Array<Electron.DevicePermissionHandlerHandlerDetails['device']>)}
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow()
win.webContents.session.setPermissionCheckHandler((webContents, permission, requestingOrigin, details) => {
if (permission === 'hid') {
// Add logic here to determine if permission should be given to allow HID selection
return true
} else if (permission === 'serial') {
// Add logic here to determine if permission should be given to allow serial port selection
} else if (permission === 'usb') {
// Add logic here to determine if permission should be given to allow USB device selection
}
return false
})
// Optionally, retrieve previously persisted devices from a persistent store
const grantedDevices = fetchGrantedDevices()
win.webContents.session.setDevicePermissionHandler((details) => {
if (new URL(details.origin).hostname === 'some-host' && details.deviceType === 'hid') {
if (details.device.vendorId === 123 && details.device.productId === 345) {
// Always allow this type of device (this allows skipping the call to `navigator.hid.requestDevice` first)
return true
}
// Search through the list of devices that have previously been granted permission
return grantedDevices.some((grantedDevice) => {
return grantedDevice.vendorId === details.device.vendorId &&
grantedDevice.productId === details.device.productId &&
grantedDevice.serialNumber && grantedDevice.serialNumber === details.device.serialNumber
})
} else if (details.deviceType === 'serial') {
if (details.device.vendorId === 123 && details.device.productId === 345) {
// Always allow this type of device (this allows skipping the call to `navigator.hid.requestDevice` first)
return true
}
}
return false
})
win.webContents.session.on('select-hid-device', (event, details, callback) => {
event.preventDefault()
const selectedDevice = details.deviceList.find((device) => {
return device.vendorId === 9025 && device.productId === 67
})
callback(selectedDevice?.deviceId)
})
})
```
#### `ses.setUSBProtectedClassesHandler(handler)`
* `handler` Function\<string[]> | null
* `details` Object
* `protectedClasses` string[] - The current list of protected USB classes. Possible class values are:
* `audio`
* `audio-video`
* `hid`
* `mass-storage`
* `smart-card`
* `video`
* `wireless`
Sets the handler which can be used to override which [USB classes are protected](https://wicg.github.io/webusb/#usbinterface-interface).
The return value for the handler is a string array of USB classes which should be considered protected (eg not available in the renderer). Valid values for the array are:
* `audio`
* `audio-video`
* `hid`
* `mass-storage`
* `smart-card`
* `video`
* `wireless`
Returning an empty string array from the handler will allow all USB classes; returning the passed in array will maintain the default list of protected USB classes (this is also the default behavior if a handler is not defined).
To clear the handler, call `setUSBProtectedClassesHandler(null)`.
```javascript
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow()
win.webContents.session.setUSBProtectedClassesHandler((details) => {
// Allow all classes:
// return []
// Keep the current set of protected classes:
// return details.protectedClasses
// Selectively remove classes:
return details.protectedClasses.filter((usbClass) => {
// Exclude classes except for audio classes
return usbClass.indexOf('audio') === -1
})
})
})
```
#### `ses.setBluetoothPairingHandler(handler)` _Windows_ _Linux_
* `handler` Function | null
* `details` Object
* `deviceId` string
* `pairingKind` string - The type of pairing prompt being requested.
One of the following values:
* `confirm`
This prompt is requesting confirmation that the Bluetooth device should
be paired.
* `confirmPin`
This prompt is requesting confirmation that the provided PIN matches the
pin displayed on the device.
* `providePin`
This prompt is requesting that a pin be provided for the device.
* `frame` [WebFrameMain](web-frame-main.md)
* `pin` string (optional) - The pin value to verify if `pairingKind` is `confirmPin`.
* `callback` Function
* `response` Object
* `confirmed` boolean - `false` should be passed in if the dialog is canceled.
If the `pairingKind` is `confirm` or `confirmPin`, this value should indicate
if the pairing is confirmed. If the `pairingKind` is `providePin` the value
should be `true` when a value is provided.
* `pin` string | null (optional) - When the `pairingKind` is `providePin`
this value should be the required pin for the Bluetooth device.
Sets a handler to respond to Bluetooth pairing requests. This handler
allows developers to handle devices that require additional validation
before pairing. When a handler is not defined, any pairing on Linux or Windows
that requires additional validation will be automatically cancelled.
macOS does not require a handler because macOS handles the pairing
automatically. To clear the handler, call `setBluetoothPairingHandler(null)`.
```javascript
const { app, BrowserWindow, session } = require('electron')
const path = require('path')
function createWindow () {
let bluetoothPinCallback = null
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
mainWindow.webContents.session.setBluetoothPairingHandler((details, callback) => {
bluetoothPinCallback = callback
// Send a IPC message to the renderer to prompt the user to confirm the pairing.
// Note that this will require logic in the renderer to handle this message and
// display a prompt to the user.
mainWindow.webContents.send('bluetooth-pairing-request', details)
})
// Listen for an IPC message from the renderer to get the response for the Bluetooth pairing.
mainWindow.webContents.ipc.on('bluetooth-pairing-response', (event, response) => {
bluetoothPinCallback(response)
})
}
app.whenReady().then(() => {
createWindow()
})
```
#### `ses.clearHostResolverCache()`
Returns `Promise<void>` - Resolves when the operation is complete.
Clears the host resolver cache.
#### `ses.allowNTLMCredentialsForDomains(domains)`
* `domains` string - A comma-separated list of servers for which
integrated authentication is enabled.
Dynamically sets whether to always send credentials for HTTP NTLM or Negotiate
authentication.
```javascript
const { session } = require('electron')
// consider any url ending with `example.com`, `foobar.com`, `baz`
// for integrated authentication.
session.defaultSession.allowNTLMCredentialsForDomains('*example.com, *foobar.com, *baz')
// consider all urls for integrated authentication.
session.defaultSession.allowNTLMCredentialsForDomains('*')
```
#### `ses.setUserAgent(userAgent[, acceptLanguages])`
* `userAgent` string
* `acceptLanguages` string (optional)
Overrides the `userAgent` and `acceptLanguages` for this session.
The `acceptLanguages` must a comma separated ordered list of language codes, for
example `"en-US,fr,de,ko,zh-CN,ja"`.
This doesn't affect existing `WebContents`, and each `WebContents` can use
`webContents.setUserAgent` to override the session-wide user agent.
#### `ses.isPersistent()`
Returns `boolean` - Whether or not this session is a persistent one. The default
`webContents` session of a `BrowserWindow` is persistent. When creating a session
from a partition, session prefixed with `persist:` will be persistent, while others
will be temporary.
#### `ses.getUserAgent()`
Returns `string` - The user agent for this session.
#### `ses.setSSLConfig(config)`
* `config` Object
* `minVersion` string (optional) - Can be `tls1`, `tls1.1`, `tls1.2` or `tls1.3`. The
minimum SSL version to allow when connecting to remote servers. Defaults to
`tls1`.
* `maxVersion` string (optional) - Can be `tls1.2` or `tls1.3`. The maximum SSL version
to allow when connecting to remote servers. Defaults to `tls1.3`.
* `disabledCipherSuites` Integer[] (optional) - List of cipher suites which
should be explicitly prevented from being used in addition to those
disabled by the net built-in policy.
Supported literal forms: 0xAABB, where AA is `cipher_suite[0]` and BB is
`cipher_suite[1]`, as defined in RFC 2246, Section 7.4.1.2. Unrecognized but
parsable cipher suites in this form will not return an error.
Ex: To disable TLS_RSA_WITH_RC4_128_MD5, specify 0x0004, while to
disable TLS_ECDH_ECDSA_WITH_RC4_128_SHA, specify 0xC002.
Note that TLSv1.3 ciphers cannot be disabled using this mechanism.
Sets the SSL configuration for the session. All subsequent network requests
will use the new configuration. Existing network connections (such as WebSocket
connections) will not be terminated, but old sockets in the pool will not be
reused for new connections.
#### `ses.getBlobData(identifier)`
* `identifier` string - Valid UUID.
Returns `Promise<Buffer>` - resolves with blob data.
#### `ses.downloadURL(url[, options])`
* `url` string
* `options` Object (optional)
* `headers` Record<string, string> (optional) - HTTP request headers.
Initiates a download of the resource at `url`.
The API will generate a [DownloadItem](download-item.md) that can be accessed
with the [will-download](#event-will-download) event.
**Note:** This does not perform any security checks that relate to a page's origin,
unlike [`webContents.downloadURL`](web-contents.md#contentsdownloadurlurl).
#### `ses.createInterruptedDownload(options)`
* `options` Object
* `path` string - Absolute path of the download.
* `urlChain` string[] - Complete URL chain for the download.
* `mimeType` string (optional)
* `offset` Integer - Start range for the download.
* `length` Integer - Total length of the download.
* `lastModified` string (optional) - Last-Modified header value.
* `eTag` string (optional) - ETag header value.
* `startTime` Double (optional) - Time when download was started in
number of seconds since UNIX epoch.
Allows resuming `cancelled` or `interrupted` downloads from previous `Session`.
The API will generate a [DownloadItem](download-item.md) that can be accessed with the [will-download](#event-will-download)
event. The [DownloadItem](download-item.md) will not have any `WebContents` associated with it and
the initial state will be `interrupted`. The download will start only when the
`resume` API is called on the [DownloadItem](download-item.md).
#### `ses.clearAuthCache()`
Returns `Promise<void>` - resolves when the session’s HTTP authentication cache has been cleared.
#### `ses.setPreloads(preloads)`
* `preloads` string[] - An array of absolute path to preload scripts
Adds scripts that will be executed on ALL web contents that are associated with
this session just before normal `preload` scripts run.
#### `ses.getPreloads()`
Returns `string[]` an array of paths to preload scripts that have been
registered.
#### `ses.setCodeCachePath(path)`
* `path` String - Absolute path to store the v8 generated JS code cache from the renderer.
Sets the directory to store the generated JS [code cache](https://v8.dev/blog/code-caching-for-devs) for this session. The directory is not required to be created by the user before this call, the runtime will create if it does not exist otherwise will use the existing directory. If directory cannot be created, then code cache will not be used and all operations related to code cache will fail silently inside the runtime. By default, the directory will be `Code Cache` under the
respective user data folder.
#### `ses.clearCodeCaches(options)`
* `options` Object
* `urls` String[] (optional) - An array of url corresponding to the resource whose generated code cache needs to be removed. If the list is empty then all entries in the cache directory will be removed.
Returns `Promise<void>` - resolves when the code cache clear operation is complete.
#### `ses.setSpellCheckerEnabled(enable)`
* `enable` boolean
Sets whether to enable the builtin spell checker.
#### `ses.isSpellCheckerEnabled()`
Returns `boolean` - Whether the builtin spell checker is enabled.
#### `ses.setSpellCheckerLanguages(languages)`
* `languages` string[] - An array of language codes to enable the spellchecker for.
The built in spellchecker does not automatically detect what language a user is typing in. In order for the
spell checker to correctly check their words you must call this API with an array of language codes. You can
get the list of supported language codes with the `ses.availableSpellCheckerLanguages` property.
**Note:** On macOS the OS spellchecker is used and will detect your language automatically. This API is a no-op on macOS.
#### `ses.getSpellCheckerLanguages()`
Returns `string[]` - An array of language codes the spellchecker is enabled for. If this list is empty the spellchecker
will fallback to using `en-US`. By default on launch if this setting is an empty list Electron will try to populate this
setting with the current OS locale. This setting is persisted across restarts.
**Note:** On macOS the OS spellchecker is used and has its own list of languages. On macOS, this API will return whichever languages have been configured by the OS.
#### `ses.setSpellCheckerDictionaryDownloadURL(url)`
* `url` string - A base URL for Electron to download hunspell dictionaries from.
By default Electron will download hunspell dictionaries from the Chromium CDN. If you want to override this
behavior you can use this API to point the dictionary downloader at your own hosted version of the hunspell
dictionaries. We publish a `hunspell_dictionaries.zip` file with each release which contains the files you need
to host here.
The file server must be **case insensitive**. If you cannot do this, you must upload each file twice: once with
the case it has in the ZIP file and once with the filename as all lowercase.
If the files present in `hunspell_dictionaries.zip` are available at `https://example.com/dictionaries/language-code.bdic`
then you should call this api with `ses.setSpellCheckerDictionaryDownloadURL('https://example.com/dictionaries/')`. Please
note the trailing slash. The URL to the dictionaries is formed as `${url}${filename}`.
**Note:** On macOS the OS spellchecker is used and therefore we do not download any dictionary files. This API is a no-op on macOS.
#### `ses.listWordsInSpellCheckerDictionary()`
Returns `Promise<string[]>` - An array of all words in app's custom dictionary.
Resolves when the full dictionary is loaded from disk.
#### `ses.addWordToSpellCheckerDictionary(word)`
* `word` string - The word you want to add to the dictionary
Returns `boolean` - Whether the word was successfully written to the custom dictionary. This API
will not work on non-persistent (in-memory) sessions.
**Note:** On macOS and Windows 10 this word will be written to the OS custom dictionary as well
#### `ses.removeWordFromSpellCheckerDictionary(word)`
* `word` string - The word you want to remove from the dictionary
Returns `boolean` - Whether the word was successfully removed from the custom dictionary. This API
will not work on non-persistent (in-memory) sessions.
**Note:** On macOS and Windows 10 this word will be removed from the OS custom dictionary as well
#### `ses.loadExtension(path[, options])`
* `path` string - Path to a directory containing an unpacked Chrome extension
* `options` Object (optional)
* `allowFileAccess` boolean - Whether to allow the extension to read local files over `file://`
protocol and inject content scripts into `file://` pages. This is required e.g. for loading
devtools extensions on `file://` URLs. Defaults to false.
Returns `Promise<Extension>` - resolves when the extension is loaded.
This method will raise an exception if the extension could not be loaded. If
there are warnings when installing the extension (e.g. if the extension
requests an API that Electron does not support) then they will be logged to the
console.
Note that Electron does not support the full range of Chrome extensions APIs.
See [Supported Extensions APIs](extensions.md#supported-extensions-apis) for
more details on what is supported.
Note that in previous versions of Electron, extensions that were loaded would
be remembered for future runs of the application. This is no longer the case:
`loadExtension` must be called on every boot of your app if you want the
extension to be loaded.
```js
const { app, session } = require('electron')
const path = require('path')
app.whenReady().then(async () => {
await session.defaultSession.loadExtension(
path.join(__dirname, 'react-devtools'),
// allowFileAccess is required to load the devtools extension on file:// URLs.
{ allowFileAccess: true }
)
// Note that in order to use the React DevTools extension, you'll need to
// download and unzip a copy of the extension.
})
```
This API does not support loading packed (.crx) extensions.
**Note:** This API cannot be called before the `ready` event of the `app` module
is emitted.
**Note:** Loading extensions into in-memory (non-persistent) sessions is not
supported and will throw an error.
#### `ses.removeExtension(extensionId)`
* `extensionId` string - ID of extension to remove
Unloads an extension.
**Note:** This API cannot be called before the `ready` event of the `app` module
is emitted.
#### `ses.getExtension(extensionId)`
* `extensionId` string - ID of extension to query
Returns `Extension` | `null` - The loaded extension with the given ID.
**Note:** This API cannot be called before the `ready` event of the `app` module
is emitted.
#### `ses.getAllExtensions()`
Returns `Extension[]` - A list of all loaded extensions.
**Note:** This API cannot be called before the `ready` event of the `app` module
is emitted.
#### `ses.getStoragePath()`
Returns `string | null` - The absolute file system path where data for this
session is persisted on disk. For in memory sessions this returns `null`.
### Instance Properties
The following properties are available on instances of `Session`:
#### `ses.availableSpellCheckerLanguages` _Readonly_
A `string[]` array which consists of all the known available spell checker languages. Providing a language
code to the `setSpellCheckerLanguages` API that isn't in this array will result in an error.
#### `ses.spellCheckerEnabled`
A `boolean` indicating whether builtin spell checker is enabled.
#### `ses.storagePath` _Readonly_
A `string | null` indicating the absolute file system path where data for this
session is persisted on disk. For in memory sessions this returns `null`.
#### `ses.cookies` _Readonly_
A [`Cookies`](cookies.md) object for this session.
#### `ses.serviceWorkers` _Readonly_
A [`ServiceWorkers`](service-workers.md) object for this session.

const path = require('path')
app.whenReady().then(() => {
const protocol = session.fromPartition('some-partition').protocol
if (!protocol.registerFileProtocol('atom', (request, callback) => {
const url = request.url.substr(7)
callback({ path: path.normalize(path.join(__dirname, url)) })
})) {
console.error('Failed to register protocol')
}
})
```
#### `ses.netLog` _Readonly_
A [`NetLog`](net-log.md) object for this session.
```javascript
const { app, session } = require('electron')
app.whenReady().then(async () => {
const netLog = session.fromPartition('some-partition').netLog

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

# webContents
> Render and control web pages.
Process: [Main](../glossary.md#main-process)
`webContents` is an [EventEmitter][event-emitter].
It is responsible for rendering and controlling a web page and is a property of
the [`BrowserWindow`](browser-window.md) object. An example of accessing the
`webContents` object:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 1500 })
win.loadURL('http://github.com')
const contents = win.webContents
console.log(contents)
```
## Navigation Events
Several events can be used to monitor navigations as they occur within a `webContents`.
### Document Navigations
When a `webContents` navigates to another page (as opposed to an [in-page navigation](web-contents.md#in-page-navigation)), the following events will be fired.
* [`did-start-navigation`](web-contents.md#event-did-start-navigation)
* [`will-frame-navigate`](web-contents.md#event-will-frame-navigate)
* [`will-navigate`](web-contents.md#event-will-navigate) (only fired when main frame navigates)
* [`will-redirect`](web-contents.md#event-will-redirect) (only fired when a redirect happens during navigation)
* [`did-redirect-navigation`](web-contents.md#event-did-redirect-navigation) (only fired when a redirect happens during navigation)
* [`did-frame-navigate`](web-contents.md#event-did-frame-navigate)
* [`did-navigate`](web-contents.md#event-did-navigate) (only fired when main frame navigates)
Subsequent events will not fire if `event.preventDefault()` is called on any of the cancellable events.
### In-page Navigation
In-page navigations don't cause the page to reload, but instead navigate to a location within the current page. These events are not cancellable. For an in-page navigations, the following events will fire in this order:
* [`did-start-navigation`](web-contents.md#event-did-start-navigation)
* [`did-navigate-in-page`](web-contents.md#event-did-navigate-in-page)
### Frame Navigation
The [`will-navigate`](web-contents.md#event-will-navigate) and [`did-navigate`](web-contents.md#event-did-navigate) events only fire when the [mainFrame](web-contents.md#contentsmainframe-readonly) navigates.
If you want to also observe navigations in `<iframe>`s, use [`will-frame-navigate`](web-contents.md#event-will-frame-navigate) and [`did-frame-navigate`](web-contents.md#event-did-frame-navigate) events.
## Methods
These methods can be accessed from the `webContents` module:
```javascript
const { webContents } = require('electron')
console.log(webContents)
```
### `webContents.getAllWebContents()`
Returns `WebContents[]` - An array of all `WebContents` instances. This will contain web contents
for all windows, webviews, opened devtools, and devtools extension background pages.
### `webContents.getFocusedWebContents()`
Returns `WebContents | null` - The web contents that is focused in this application, otherwise
returns `null`.
### `webContents.fromId(id)`
* `id` Integer
Returns `WebContents | undefined` - A WebContents instance with the given ID, or
`undefined` if there is no WebContents associated with the given ID.
### `webContents.fromFrame(frame)`
* `frame` WebFrameMain
Returns `WebContents | undefined` - A WebContents instance with the given WebFrameMain, or
`undefined` if there is no WebContents associated with the given WebFrameMain.
### `webContents.fromDevToolsTargetId(targetId)`
* `targetId` string - The Chrome DevTools Protocol [TargetID](https://chromedevtools.github.io/devtools-protocol/tot/Target/#type-TargetID) associated with the WebContents instance.
Returns `WebContents | undefined` - A WebContents instance with the given TargetID, or
`undefined` if there is no WebContents associated with the given TargetID.
When communicating with the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/),
it can be useful to lookup a WebContents instance based on its assigned TargetID.
```js
async function lookupTargetId (browserWindow) {
const wc = browserWindow.webContents
await wc.debugger.attach('1.3')
const { targetInfo } = await wc.debugger.sendCommand('Target.getTargetInfo')
const { targetId } = targetInfo
const targetWebContents = await wc.fromDevToolsTargetId(targetId)
}
```
## Class: WebContents
> Render and control the contents of a BrowserWindow instance.
Process: [Main](../glossary.md#main-process)<br />
_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
### Instance Events
#### Event: 'did-finish-load'
Emitted when the navigation is done, i.e. the spinner of the tab has stopped
spinning, and the `onload` event was dispatched.
#### Event: 'did-fail-load'
Returns:
* `event` Event
* `errorCode` Integer
* `errorDescription` string
* `validatedURL` string
* `isMainFrame` boolean
* `frameProcessId` Integer

#### Event: 'did-fail-provisional-load'
Returns:
* `event` Event
* `errorCode` Integer
* `errorDescription` string
* `validatedURL` string
* `isMainFrame` boolean
* `frameProcessId` Integer

* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when a frame has done navigation.
#### Event: 'did-start-loading'
Corresponds to the points in time when the spinner of the tab started spinning.
#### Event: 'did-stop-loading'
Corresponds to the points in time when the spinner of the tab stopped spinning.
#### Event: 'dom-ready'
Emitted when the document in the top-level frame is loaded.
#### Event: 'page-title-updated'
Returns:
* `event` Event
* `title` string
* `explicitSet` boolean
Fired when page title is set during navigation. `explicitSet` is false when
title is synthesized from file url.
#### Event: 'page-favicon-updated'
Returns:
* `event` Event
* `favicons` string[] - Array of URLs.
Emitted when page receives favicon urls.
#### Event: 'content-bounds-updated'
Returns:
* `event` Event
* `bounds` [Rectangle](structures/rectangle.md) - requested new content bounds
Emitted when the page calls `window.moveTo`, `window.resizeTo` or related APIs.
By default, this will move the window. To prevent that behavior, call
`event.preventDefault()`.
#### Event: 'did-create-window'
Returns:
* `window` BrowserWindow
* `details` Object
* `url` string - URL for the created window.
* `frameName` string - Name given to the created window in the
`window.open()` call.
* `options` [BrowserWindowConstructorOptions](structures/browser-window-options.md) - The options used to create the
BrowserWindow. They are merged in increasing precedence: parsed options
from the `features` string from `window.open()`, security-related
webPreferences inherited from the parent, and options given by
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
Unrecognized options are not filtered out.
* `referrer` [Referrer](structures/referrer.md) - The referrer that will be
passed to the new window. May or may not result in the `Referer` header
being sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data
that will be sent to the new window, along with the appropriate headers
that will be set. If no post data is to be sent, the value will be `null`.
Only defined when the window is being created by a form that set
`target=_blank`.
* `disposition` string - Can be `default`, `foreground-tab`,
`background-tab`, `new-window` or `other`.
Emitted _after_ successful creation of a window via `window.open` in the renderer.
Not emitted if the creation of the window is canceled from
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
See [`window.open()`](window-open.md) for more details and how to use this in conjunction with `webContents.setWindowOpenHandler`.
#### Event: 'will-navigate'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - This event does not fire for same document navigations using window.history api and reference fragment navigations.
This property is always set to `false` for this event.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
* `url` string _Deprecated_
* `isInPlace` boolean _Deprecated_
* `isMainFrame` boolean _Deprecated_
* `frameProcessId` Integer _Deprecated_
* `frameRoutingId` Integer _Deprecated_
Emitted when a user or the page wants to start navigation on the main frame. It can happen when
the `window.location` object is changed or a user clicks a link in the page.
This event will not emit when the navigation is started programmatically with
APIs like `webContents.loadURL` and `webContents.back`.
It is also not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` will prevent the navigation.
#### Event: 'will-frame-navigate'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - This event does not fire for same document navigations using window.history api and reference fragment navigations.
This property is always set to `false` for this event.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
Emitted when a user or the page wants to start navigation in any frame. It can happen when
the `window.location` object is changed or a user clicks a link in the page.
Unlike `will-navigate`, `will-frame-navigate` is fired when the main frame or any of its subframes attempts to navigate. When the navigation event comes from the main frame, `isMainFrame` will be `true`.
This event will not emit when the navigation is started programmatically with
APIs like `webContents.loadURL` and `webContents.back`.
It is also not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` will prevent the navigation.
#### Event: 'did-start-navigation'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - Whether the navigation happened without changing
document. Examples of same document navigations are reference fragment
navigations, pushState/replaceState, and same page history navigation.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
* `url` string _Deprecated_
* `isInPlace` boolean _Deprecated_
* `isMainFrame` boolean _Deprecated_
* `frameProcessId` Integer _Deprecated_
* `frameRoutingId` Integer _Deprecated_
Emitted when any frame (including main) starts navigating.
#### Event: 'will-redirect'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - Whether the navigation happened without changing
document. Examples of same document navigations are reference fragment
navigations, pushState/replaceState, and same page history navigation.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
* `url` string _Deprecated_
* `isInPlace` boolean _Deprecated_
* `isMainFrame` boolean _Deprecated_
* `frameProcessId` Integer _Deprecated_
* `frameRoutingId` Integer _Deprecated_
Emitted when a server side redirect occurs during navigation. For example a 302
redirect.
This event will be emitted after `did-start-navigation` and always before the
`did-redirect-navigation` event for the same navigation.
Calling `event.preventDefault()` will prevent the navigation (not just the
redirect).
#### Event: 'did-redirect-navigation'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - Whether the navigation happened without changing
document. Examples of same document navigations are reference fragment
navigations, pushState/replaceState, and same page history navigation.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
* `url` string _Deprecated_
* `isInPlace` boolean _Deprecated_
* `isMainFrame` boolean _Deprecated_
* `frameProcessId` Integer _Deprecated_
* `frameRoutingId` Integer _Deprecated_
Emitted after a server side redirect occurs during navigation. For example a 302
redirect.
This event cannot be prevented, if you want to prevent redirects you should
checkout out the `will-redirect` event above.
#### Event: 'did-navigate'
Returns:
* `event` Event
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations
Emitted when a main frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
#### Event: 'did-frame-navigate'
Returns:
* `event` Event
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations,
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when any frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
#### Event: 'did-navigate-in-page'
Returns:
* `event` Event
* `url` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when an in-page navigation happened in any frame.
When in-page navigation happens, the page URL changes but does not cause
navigation outside of the page. Examples of this occurring are when anchor links
are clicked or when the DOM `hashchange` event is triggered.
#### Event: 'will-prevent-unload'
Returns:
* `event` Event
Emitted when a `beforeunload` event handler is attempting to cancel a page unload.
Calling `event.preventDefault()` will ignore the `beforeunload` event handler
and allow the page to be unloaded.
```javascript
const { BrowserWindow, dialog } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('will-prevent-unload', (event) => {
const choice = dialog.showMessageBoxSync(win, {
type: 'question',
buttons: ['Leave', 'Stay'],
title: 'Do you want to leave this site?',
message: 'Changes you made may not be saved.',
defaultId: 0,
cancelId: 1
})
const leave = (choice === 0)
if (leave) {
event.preventDefault()
}
})
```
**Note:** This will be emitted for `BrowserViews` but will _not_ be respected - this is because we have chosen not to tie the `BrowserView` lifecycle to its owning BrowserWindow should one exist per the [specification](https://developer.mozilla.org/en-US/docs/Web/API/Window/beforeunload_event).
#### Event: 'crashed' _Deprecated_
Returns:
* `event` Event
* `killed` boolean
Emitted when the renderer process crashes or is killed.
**Deprecated:** This event is superceded by the `render-process-gone` event

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
* `details` Object
* `reason` string - The reason the render process is gone. Possible values:
* `clean-exit` - Process exited with an exit code of zero

* `crashed` - Process crashed
* `oom` - Process ran out of memory
* `launch-failed` - Process never successfully launched
* `integrity-failure` - Windows code integrity checks failed
* `exitCode` Integer - The exit code of the process, unless `reason` is
`launch-failed`, in which case `exitCode` will be a platform-specific
launch failure error code.
Emitted when the renderer process unexpectedly disappears. This is normally
because it was crashed or killed.
#### Event: 'unresponsive'

Calling `event.preventDefault` will prevent the page `keydown`/`keyup` events
and the menu shortcuts.
To only prevent the menu shortcuts, use
[`setIgnoreMenuShortcuts`](#contentssetignoremenushortcutsignore):
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('before-input-event', (event, input) => {
// For example, only enable application menu keyboard shortcuts when
// Ctrl/Cmd are down.
win.webContents.setIgnoreMenuShortcuts(!input.control && !input.meta)
})
```
#### Event: 'enter-html-full-screen'
Emitted when the window enters a full-screen state triggered by HTML API.

#### Event: 'blur'
Emitted when the `WebContents` loses focus.
#### Event: 'focus'

of window, so switching focus between windows would not trigger the `focus` and
`blur` events of `WebContents`, as the first responder of each window is not
changed.
The `focus` and `blur` events of `WebContents` should only be used to detect
focus change between different `WebContents` and `BrowserView` in the same
window.

If an event listener is not added for this event, or if `event.preventDefault`
is not called when handling this event, the first available device will be
automatically selected.
Due to the nature of bluetooth, scanning for devices when
`navigator.bluetooth.requestDevice` is called may take time and will cause
`select-bluetooth-device` to fire multiple times until `callback` is called
with either a device id or an empty string to cancel the request.

win.webContents.on('select-bluetooth-device', (event, deviceList, callback) => {
event.preventDefault()
const result = deviceList.find((device) => {
return device.deviceName === 'test'
})
if (!result) {
// The device wasn't found so we need to either wait longer (eg until the

// with an empty string.
callback('')
} else {
callback(result.deviceId)
}
})
})
```

### Instance Methods
#### `contents.loadURL(url[, options])`
* `url` string
* `options` Object (optional)
* `httpReferrer` (string | [Referrer](structures/referrer.md)) (optional) - An HTTP Referrer url.
* `userAgent` string (optional) - A user agent originating the request.
* `extraHeaders` string (optional) - Extra headers separated by "\n".
* `postData` ([UploadRawData](structures/upload-raw-data.md) | [UploadFile](structures/upload-file.md))[] (optional)
* `baseURLForDataURL` string (optional) - Base url (with trailing path separator) for files to be loaded by the data url. This is needed only if the specified `url` is a data url and needs to load other files.
Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see
[`did-fail-load`](web-contents.md#event-did-fail-load)). A noop rejection handler is already attached, which avoids unhandled rejection errors.
Loads the `url` in the window. The `url` must contain the protocol prefix,
e.g. the `http://` or `file://`. If the load should bypass http cache then
use the `pragma` header to achieve it.
```javascript
const win = new BrowserWindow()
const options = { extraHeaders: 'pragma: no-cache\n' }
win.webContents.loadURL('https://github.com', options)
```
#### `contents.loadFile(filePath[, options])`
* `filePath` string
* `options` Object (optional)
* `query` Record<string, string> (optional) - Passed to `url.format()`.
* `search` string (optional) - Passed to `url.format()`.
* `hash` string (optional) - Passed to `url.format()`.
Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Loads the given file in the window, `filePath` should be a path to
an HTML file relative to the root of your application. For instance
an app structure like this:
```sh
| root
| - package.json
| - src
| - main.js
| - index.html
```
Would require code like this
```js
const win = new BrowserWindow()
win.loadFile('src/index.html')
```
#### `contents.downloadURL(url)`
* `url` string
Initiates a download of the resource at `url` without navigating. The
`will-download` event of `session` will be triggered.
#### `contents.getURL()`
Returns `string` - The URL of the current web page.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.loadURL('http://github.com').then(() => {
const currentURL = win.webContents.getURL()
console.log(currentURL)
})
```
#### `contents.getTitle()`
Returns `string` - The title of the current web page.
#### `contents.isDestroyed()`
Returns `boolean` - Whether the web page is destroyed.
#### `contents.close([opts])`
* `opts` Object (optional)
* `waitForBeforeUnload` boolean - if true, fire the `beforeunload` event
before closing the page. If the page prevents the unload, the WebContents
will not be closed. The [`will-prevent-unload`](#event-will-prevent-unload)
will be fired if the page requests prevention of unload.
Closes the page, as if the web content had called `window.close()`.
If the page is successfully closed (i.e. the unload is not prevented by the
page, or `waitForBeforeUnload` is false or unspecified), the WebContents will
be destroyed and no longer usable. The [`destroyed`](#event-destroyed) event
will be emitted.
#### `contents.focus()`
Focuses the web page.
#### `contents.isFocused()`
Returns `boolean` - Whether the web page is focused.
#### `contents.isLoading()`
Returns `boolean` - Whether web page is still loading resources.
#### `contents.isLoadingMainFrame()`
Returns `boolean` - Whether the main frame (and not just iframes or frames within it) is
still loading.
#### `contents.isWaitingForResponse()`
Returns `boolean` - Whether the web page is waiting for a first-response from the main
resource of the page.

Returns `boolean` - Whether the web page can go to `offset`.
#### `contents.clearHistory()`
Clears the navigation history.
#### `contents.goBack()`
Makes the browser go back a web page.
#### `contents.goForward()`
Makes the browser go forward a web page.
#### `contents.goToIndex(index)`
* `index` Integer

#### `contents.isCrashed()`
Returns `boolean` - Whether the renderer process has crashed.
#### `contents.forcefullyCrashRenderer()`
Forcefully terminates the renderer process that is currently hosting this
`webContents`. This will cause the `render-process-gone` event to be emitted
with the `reason=killed || reason=crashed`. Please note that some webContents share renderer
processes and therefore calling this method may also crash the host process
for other webContents as well.
Calling `reload()` immediately after calling this
method will force the reload to occur in a new process. This should be used
when this process is unstable or unusable, for instance in order to recover
from the `unresponsive` event.
```js
const win = new BrowserWindow()
win.webContents.on('unresponsive', async () => {
const { response } = await dialog.showMessageBox({
message: 'App X has become unresponsive',
title: 'Do you want to try forcefully reloading the app?',
buttons: ['OK', 'Cancel'],
cancelId: 1
})
if (response === 0) {
win.webContents.forcefullyCrashRenderer()
win.webContents.reload()
}
})
```

Returns `Promise<string>` - A promise that resolves with a key for the inserted CSS that can later be used to remove the CSS via `contents.removeInsertedCSS(key)`.
Injects CSS into the current web page and returns a unique key for the inserted
stylesheet.
```js
const win = new BrowserWindow()
win.webContents.on('did-finish-load', () => {
win.webContents.insertCSS('html, body { background-color: #f00; }')
})
```
#### `contents.removeInsertedCSS(key)`
* `key` string
Returns `Promise<void>` - Resolves if the removal was successful.
Removes the inserted CSS from the current web page. The stylesheet is identified
by its key, which is returned from `contents.insertCSS(css)`.
```js
const win = new BrowserWindow()
win.webContents.on('did-finish-load', async () => {
const key = await win.webContents.insertCSS('html, body { background-color: #f00; }')
win.webContents.removeInsertedCSS(key)
})
```
#### `contents.executeJavaScript(code[, userGesture])`
* `code` string
* `userGesture` boolean (optional) - Default is `false`.
Returns `Promise<any>` - A promise that resolves with the result of the executed code
or is rejected if the result of the code is a rejected promise.
Evaluates `code` in page.
In the browser window some HTML APIs like `requestFullScreen` can only be
invoked by a gesture from the user. Setting `userGesture` to `true` will remove
this limitation.
Code execution will be suspended until web page stop loading.
```js
const win = new BrowserWindow()
win.webContents.executeJavaScript('fetch("https://jsonplaceholder.typicode.com/users/1").then(resp => resp.json())', true)
.then((result) => {
console.log(result) // Will be the JSON object from the fetch call
})
```
#### `contents.executeJavaScriptInIsolatedWorld(worldId, scripts[, userGesture])`
* `worldId` Integer - The ID of the world to run the javascript in, `0` is the default world, `999` is the world used by Electron's `contextIsolation` feature. You can provide any integer here.
* `scripts` [WebSource[]](structures/web-source.md)
* `userGesture` boolean (optional) - Default is `false`.
Returns `Promise<any>` - A promise that resolves with the result of the executed code
or is rejected if the result of the code is a rejected promise.
Works like `executeJavaScript` but evaluates `scripts` in an isolated context.
#### `contents.setIgnoreMenuShortcuts(ignore)`
* `ignore` boolean
Ignore application menu shortcuts while this web contents is focused.
#### `contents.setWindowOpenHandler(handler)`
* `handler` Function<{action: 'deny'} | {action: 'allow', outlivesOpener?: boolean, overrideBrowserWindowOptions?: BrowserWindowConstructorOptions}>
* `details` Object
* `url` string - The _resolved_ version of the URL passed to `window.open()`. e.g. opening a window with `window.open('foo')` will yield something like `https://the-origin/the/current/path/foo`.
* `frameName` string - Name of the window provided in `window.open()`
* `features` string - Comma separated list of window features provided to `window.open()`.
* `disposition` string - Can be `default`, `foreground-tab`, `background-tab`,
`new-window` or `other`.
* `referrer` [Referrer](structures/referrer.md) - The referrer that will be
passed to the new window. May or may not result in the `Referer` header being
sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data that
will be sent to the new window, along with the appropriate headers that will
be set. If no post data is to be sent, the value will be `null`. Only defined
when the window is being created by a form that set `target=_blank`.
Returns `{action: 'deny'} | {action: 'allow', outlivesOpener?: boolean, overrideBrowserWindowOptions?: BrowserWindowConstructorOptions}` - `deny` cancels the creation of the new
window. `allow` will allow the new window to be created. Specifying `overrideBrowserWindowOptions` allows customization of the created window.
By default, child windows are closed when their opener is closed. This can be
changed by specifying `outlivesOpener: true`, in which case the opened window
will not be closed when its opener is closed.
Returning an unrecognized value such as a null, undefined, or an object
without a recognized 'action' value will result in a console error and have
the same effect as returning `{action: 'deny'}`.
Called before creating a window a new window is requested by the renderer, e.g.
by `window.open()`, a link with `target="_blank"`, shift+clicking on a link, or
submitting a form with `<form target="_blank">`. See
[`window.open()`](window-open.md) for more details and how to use this in
conjunction with `did-create-window`.
#### `contents.setAudioMuted(muted)`

zoom percent divided by 100, so 300% = 3.0.
The factor must be greater than 0.0.
#### `contents.getZoomFactor()`
Returns `number` - the current zoom factor.
#### `contents.setZoomLevel(level)`
* `level` number - Zoom level.
Changes the zoom level to the specified level. The original size is 0 and each
increment above or below represents zooming 20% larger or smaller to default
limits of 300% and 50% of original size, respectively. The formula for this is
`scale := 1.2 ^ level`.
> **NOTE**: The zoom policy at the Chromium level is same-origin, meaning that the
> zoom level for a specific domain propagates across all instances of windows with
> the same domain. Differentiating the window URLs will make zoom work per-window.
#### `contents.getZoomLevel()`
Returns `number` - the current zoom level.
#### `contents.setVisualZoomLevelLimits(minimumLevel, maximumLevel)`
* `minimumLevel` number
* `maximumLevel` number
Returns `Promise<void>`
Sets the maximum and minimum pinch-to-zoom level.
> **NOTE**: Visual zoom is disabled by default in Electron. To re-enable it, call:

#### `contents.addWorkSpace(path)`
* `path` string
Adds the specified path to DevTools workspace. Must be used after DevTools
creation:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.webContents.on('devtools-opened', () => {
win.webContents.addWorkSpace(__dirname)
})
```
#### `contents.removeWorkSpace(path)`
* `path` string
Removes the specified path from DevTools workspace.
#### `contents.setDevToolsWebContents(devToolsWebContents)`
* `devToolsWebContents` WebContents
Uses the `devToolsWebContents` as the target `WebContents` to show devtools.
The `devToolsWebContents` must not have done any navigation, and it should not
be used for other purposes after the call.
By default Electron manages the devtools by creating an internal `WebContents`
with native view, which developers have very limited control of. With the
`setDevToolsWebContents` method, developers can use any `WebContents` to show
the devtools in it, including `BrowserWindow`, `BrowserView` and `<webview>`
tag.
Note that closing the devtools does not destroy the `devToolsWebContents`, it
is caller's responsibility to destroy `devToolsWebContents`.
An example of showing devtools in a `<webview>` tag:
```html
<html>
<head>
<style type="text/css">
* { margin: 0; }
#browser { height: 70%; }
#devtools { height: 30%; }
</style>
</head>
<body>
<webview id="browser" src="https://github.com"></webview>
<webview id="devtools" src="about:blank"></webview>
<script>
const { ipcRenderer } = require('electron')
const emittedOnce = (element, eventName) => new Promise(resolve => {
element.addEventListener(eventName, event => resolve(event), { once: true })
})
const browserView = document.getElementById('browser')
const devtoolsView = document.getElementById('devtools')
const browserReady = emittedOnce(browserView, 'dom-ready')
const devtoolsReady = emittedOnce(devtoolsView, 'dom-ready')
Promise.all([browserReady, devtoolsReady]).then(() => {
const targetId = browserView.getWebContentsId()
const devtoolsId = devtoolsView.getWebContentsId()
ipcRenderer.send('open-devtools', targetId, devtoolsId)
})
</script>
</body>
</html>
```
```js
// Main process
const { ipcMain, webContents } = require('electron')
ipcMain.on('open-devtools', (event, targetContentsId, devtoolsContentsId) => {
const target = webContents.fromId(targetContentsId)
const devtools = webContents.fromId(devtoolsContentsId)
target.setDevToolsWebContents(devtools)
target.openDevTools()
})
```
An example of showing devtools in a `BrowserWindow`:
```js title='main.js'
const { app, BrowserWindow } = require('electron')
let win = null
let devtools = null
app.whenReady().then(() => {
win = new BrowserWindow()
devtools = new BrowserWindow()
win.loadURL('https://github.com')
win.webContents.setDevToolsWebContents(devtools.webContents)
win.webContents.openDevTools({ mode: 'detach' })
})
```
#### `contents.openDevTools([options])`
* `options` Object (optional)
* `mode` string - Opens the devtools with specified dock state, can be
`left`, `right`, `bottom`, `undocked`, `detach`. Defaults to last used dock state.
In `undocked` mode it's possible to dock back. In `detach` mode it's not.
* `activate` boolean (optional) - Whether to bring the opened devtools window
to the foreground. The default is `true`.
Opens the devtools.
When `contents` is a `<webview>` tag, the `mode` would be `detach` by default,
explicitly passing an empty `mode` can force using last used dock state.
On Windows, if Windows Control Overlay is enabled, Devtools will be opened with `mode: 'detach'`.
#### `contents.closeDevTools()`
Closes the devtools.
#### `contents.isDevToolsOpened()`
Returns `boolean` - Whether the devtools is opened.
#### `contents.isDevToolsFocused()`
Returns `boolean` - Whether the devtools view is focused .
#### `contents.toggleDevTools()`
Toggles the developer tools.
#### `contents.inspectElement(x, y)`
* `x` Integer
* `y` Integer
Starts inspecting element at position (`x`, `y`).
#### `contents.inspectSharedWorker()`
Opens the developer tools for the shared worker context.
#### `contents.inspectSharedWorkerById(workerId)`
* `workerId` string
Inspects the shared worker based on its ID.
#### `contents.getAllSharedWorkers()`
Returns [`SharedWorkerInfo[]`](structures/shared-worker-info.md) - Information about all Shared Workers.
#### `contents.inspectServiceWorker()`
Opens the developer tools for the service worker context.
#### `contents.send(channel, ...args)`
* `channel` string
* `...args` any[]
Send an asynchronous message to the renderer process via `channel`, along with
arguments. Arguments will be serialized with the [Structured Clone
Algorithm][SCA], just like [`postMessage`][], so prototype chains will not be
included. Sending Functions, Promises, Symbols, WeakMaps, or WeakSets will
throw an exception.
:::warning
Sending non-standard JavaScript types such as DOM objects or
special Electron objects will throw an exception.
:::
For additional reading, refer to [Electron's IPC guide](../tutorial/ipc.md).
#### `contents.sendToFrame(frameId, channel, ...args)`
* `frameId` Integer | \[number, number] - the ID of the frame to send to, or a
pair of `[processId, frameId]` if the frame is in a different process to the
main frame.
* `channel` string
* `...args` any[]
Send an asynchronous message to a specific frame in a renderer process via
`channel`, along with arguments. Arguments will be serialized with the
[Structured Clone Algorithm][SCA], just like [`postMessage`][], so prototype
chains will not be included. Sending Functions, Promises, Symbols, WeakMaps, or
WeakSets will throw an exception.
> **NOTE:** Sending non-standard JavaScript types such as DOM objects or
> special Electron objects will throw an exception.
The renderer process can handle the message by listening to `channel` with the
[`ipcRenderer`](ipc-renderer.md) module.
If you want to get the `frameId` of a given renderer context you should use
the `webFrame.routingId` value. E.g.
```js
// In a renderer process
console.log('My frameId is:', require('electron').webFrame.routingId)
```
You can also read `frameId` from all incoming IPC messages in the main process.
```js
// In the main process
ipcMain.on('ping', (event) => {
console.info('Message came from frameId:', event.frameId)
})
```
#### `contents.postMessage(channel, message, [transfer])`
* `channel` string
* `message` any
* `transfer` MessagePortMain[] (optional)
Send a message to the renderer process, optionally transferring ownership of
zero or more [`MessagePortMain`][] objects.
The transferred `MessagePortMain` objects will be available in the renderer
process by accessing the `ports` property of the emitted event. When they
arrive in the renderer, they will be native DOM `MessagePort` objects.
For example:
```js
// Main process
const win = new BrowserWindow()
const { port1, port2 } = new MessageChannelMain()
win.webContents.postMessage('port', { message: 'hello' }, [port1])
// Renderer process
ipcRenderer.on('port', (e, msg) => {
const [port] = e.ports
// ...
})
```
#### `contents.enableDeviceEmulation(parameters)`
* `parameters` Object
* `screenPosition` string - Specify the screen type to emulate
(default: `desktop`):
* `desktop` - Desktop screen type.
* `mobile` - Mobile screen type.
* `screenSize` [Size](structures/size.md) - Set the emulated screen size (screenPosition == mobile).
* `viewPosition` [Point](structures/point.md) - Position the view on the screen
(screenPosition == mobile) (default: `{ x: 0, y: 0 }`).
* `deviceScaleFactor` Integer - Set the device scale factor (if zero defaults to
original device scale factor) (default: `0`).
* `viewSize` [Size](structures/size.md) - Set the emulated view size (empty means no override)
* `scale` Float - Scale of emulated view inside available space (not in fit to
view mode) (default: `1`).
Enable device emulation with the given parameters.
#### `contents.disableDeviceEmulation()`
Disable device emulation enabled by `webContents.enableDeviceEmulation`.
#### `contents.sendInputEvent(inputEvent)`
* `inputEvent` [MouseInputEvent](structures/mouse-input-event.md) | [MouseWheelInputEvent](structures/mouse-wheel-input-event.md) | [KeyboardInputEvent](structures/keyboard-input-event.md)
Sends an input `event` to the page.
**Note:** The [`BrowserWindow`](browser-window.md) containing the contents needs to be focused for
`sendInputEvent()` to work.
#### `contents.beginFrameSubscription([onlyDirty ,]callback)`
* `onlyDirty` boolean (optional) - Defaults to `false`.
* `callback` Function
* `image` [NativeImage](native-image.md)
* `dirtyRect` [Rectangle](structures/rectangle.md)
Begin subscribing for presentation events and captured frames, the `callback`
will be called with `callback(image, dirtyRect)` when there is a presentation
event.
The `image` is an instance of [NativeImage](native-image.md) that stores the
captured frame.
The `dirtyRect` is an object with `x, y, width, height` properties that
describes which part of the page was repainted. If `onlyDirty` is set to
`true`, `image` will only contain the repainted area. `onlyDirty` defaults to
`false`.
#### `contents.endFrameSubscription()`
End subscribing for frame presentation events.
#### `contents.startDrag(item)`
* `item` Object
* `file` string - The path to the file being dragged.
* `files` string[] (optional) - The paths to the files being dragged. (`files` will override `file` field)
* `icon` [NativeImage](native-image.md) | string - The image must be
non-empty on macOS.
Sets the `item` as dragging item for current drag-drop operation, `file` is the
absolute path of the file to be dragged, and `icon` is the image showing under
the cursor when dragging.
#### `contents.savePage(fullPath, saveType)`
* `fullPath` string - The absolute file path.
* `saveType` string - Specify the save type.
* `HTMLOnly` - Save only the HTML of the page.
* `HTMLComplete` - Save complete-html page.
* `MHTML` - Save complete-html page as MHTML.
Returns `Promise<void>` - resolves if the page is saved.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.loadURL('https://github.com')
win.webContents.on('did-finish-load', async () => {
win.webContents.savePage('/tmp/test.html', 'HTMLComplete').then(() => {
console.log('Page was saved successfully.')
}).catch(err => {
console.log(err)
})
})
```
#### `contents.showDefinitionForSelection()` _macOS_
Shows pop-up dictionary that searches the selected word on the page.
#### `contents.isOffscreen()`
Returns `boolean` - Indicates whether _offscreen rendering_ is enabled.
#### `contents.startPainting()`
If _offscreen rendering_ is enabled and not painting, start painting.
#### `contents.stopPainting()`
If _offscreen rendering_ is enabled and painting, stop painting.
#### `contents.isPainting()`
Returns `boolean` - If _offscreen rendering_ is enabled returns whether it is currently painting.
#### `contents.setFrameRate(fps)`
* `fps` Integer
If _offscreen rendering_ is enabled sets the frame rate to the specified number.
Only values between 1 and 240 are accepted.
#### `contents.getFrameRate()`
Returns `Integer` - If _offscreen rendering_ is enabled returns the current frame rate.
#### `contents.invalidate()`
Schedules a full repaint of the window this web contents is in.
If _offscreen rendering_ is enabled invalidates the frame and generates a new
one through the `'paint'` event.
#### `contents.getWebRTCIPHandlingPolicy()`
Returns `string` - Returns the WebRTC IP Handling Policy.
#### `contents.setWebRTCIPHandlingPolicy(policy)`
* `policy` string - Specify the WebRTC IP Handling Policy.
* `default` - Exposes user's public and local IPs. This is the default
behavior. When this policy is used, WebRTC has the right to enumerate all
interfaces and bind them to discover public interfaces.
* `default_public_interface_only` - Exposes user's public IP, but does not
expose user's local IP. When this policy is used, WebRTC should only use the
default route used by http. This doesn't expose any local addresses.
* `default_public_and_private_interfaces` - Exposes user's public and local
IPs. When this policy is used, WebRTC should only use the default route used
by http. This also exposes the associated default private address. Default
route is the route chosen by the OS on a multi-homed endpoint.
* `disable_non_proxied_udp` - Does not expose public or local IPs. When this
policy is used, WebRTC should only use TCP to contact peers or servers unless
the proxy server supports UDP.
Setting the WebRTC IP handling policy allows you to control which IPs are
exposed via WebRTC. See [BrowserLeaks](https://browserleaks.com/webrtc) for
more details.
#### `contents.getMediaSourceId(requestWebContents)`
* `requestWebContents` WebContents - Web contents that the id will be registered to.
Returns `string` - The identifier of a WebContents stream. This identifier can be used
with `navigator.mediaDevices.getUserMedia` using a `chromeMediaSource` of `tab`.
The identifier is restricted to the web contents that it is registered to and is only valid for 10 seconds.
#### `contents.getOSProcessId()`
Returns `Integer` - The operating system `pid` of the associated renderer
process.
#### `contents.getProcessId()`
Returns `Integer` - The Chromium internal `pid` of the associated renderer. Can
be compared to the `frameProcessId` passed by frame specific navigation events
(e.g. `did-frame-navigate`)
#### `contents.takeHeapSnapshot(filePath)`
* `filePath` string - Path to the output file.
Returns `Promise<void>` - Indicates whether the snapshot has been created successfully.
Takes a V8 heap snapshot and saves it to `filePath`.
#### `contents.getBackgroundThrottling()`
Returns `boolean` - whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.setBackgroundThrottling(allowed)`
* `allowed` boolean
Controls whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.getType()`
Returns `string` - the type of the webContent. Can be `backgroundPage`, `window`, `browserView`, `remote`, `webview` or `offscreen`.
#### `contents.setImageAnimationPolicy(policy)`
* `policy` string - Can be `animate`, `animateOnce` or `noAnimation`.
Sets the image animation policy for this webContents. The policy only affects
_new_ images, existing images that are currently being animated are unaffected.
This is a known limitation in Chromium, you can force image animation to be
recalculated with `img.src = img.src` which will result in no network traffic
but will update the animation policy.
This corresponds to the [animationPolicy][] accessibility feature in Chromium.
[animationPolicy]: https://developer.chrome.com/docs/extensions/reference/accessibilityFeatures/#property-animationPolicy
### Instance Properties
#### `contents.ipc` _Readonly_
An [`IpcMain`](ipc-main.md) scoped to just IPC messages sent from this
WebContents.
IPC messages sent with `ipcRenderer.send`, `ipcRenderer.sendSync` or
`ipcRenderer.postMessage` will be delivered in the following order:
1. `contents.on('ipc-message')`
2. `contents.mainFrame.on(channel)`
3. `contents.ipc.on(channel)`
4. `ipcMain.on(channel)`
Handlers registered with `invoke` will be checked in the following order. The
first one that is defined will be called, the rest will be ignored.
1. `contents.mainFrame.handle(channel)`
2. `contents.handle(channel)`
3. `ipcMain.handle(channel)`
A handler or event listener registered on the WebContents will receive IPC
messages sent from any frame, including child frames. In most cases, only the
main frame can send IPC messages. However, if the `nodeIntegrationInSubFrames`
option is enabled, it is possible for child frames to send IPC messages also.
In that case, handlers should check the `senderFrame` property of the IPC event
to ensure that the message is coming from the expected frame. Alternatively,
register handlers on the appropriate frame directly using the
[`WebFrameMain.ipc`](web-frame-main.md#frameipc-readonly) interface.
#### `contents.audioMuted`
A `boolean` property that determines whether this page is muted.
#### `contents.userAgent`
A `string` property that determines the user agent for this web page.
#### `contents.zoomLevel`
A `number` property that determines the zoom level for this web contents.
The original size is 0 and each increment above or below represents zooming 20% larger or smaller to default limits of 300% and 50% of original size, respectively. The formula for this is `scale := 1.2 ^ level`.
#### `contents.zoomFactor`
A `number` property that determines the zoom factor for this web contents.
The zoom factor is the zoom percent divided by 100, so 300% = 3.0.
#### `contents.frameRate`
An `Integer` property that sets the frame rate of the web contents to the specified number.
Only values between 1 and 240 are accepted.
Only applicable if _offscreen rendering_ is enabled.
#### `contents.id` _Readonly_
A `Integer` representing the unique ID of this WebContents. Each ID is unique among all `WebContents` instances of the entire Electron application.
#### `contents.session` _Readonly_
A [`Session`](session.md) used by this webContents.
#### `contents.hostWebContents` _Readonly_
A [`WebContents`](web-contents.md) instance that might own this `WebContents`.
#### `contents.devToolsWebContents` _Readonly_
A `WebContents | null` property that represents the of DevTools `WebContents` associated with a given `WebContents`.
**Note:** Users should never store this object because it may become `null`
when the DevTools has been closed.
#### `contents.debugger` _Readonly_
A [`Debugger`](debugger.md) instance for this webContents.
#### `contents.backgroundThrottling`
A `boolean` property that determines whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.mainFrame` _Readonly_
A [`WebFrameMain`](web-frame-main.md) property that represents the top frame of the page's frame hierarchy.
#### `contents.opener` _Readonly_
A [`WebFrameMain`](web-frame-main.md) property that represents the frame that opened this WebContents, either
with open(), or by navigating a link with a target attribute.

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

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

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

# desktopCapturer
> Access information about media sources that can be used to capture audio and
> video from the desktop using the [`navigator.mediaDevices.getUserMedia`][] API.
Process: [Main](../glossary.md#main-process)
The following example shows how to capture video from a desktop window whose
title is `Electron`:
```javascript
// In the main process.
const { BrowserWindow, desktopCapturer } = require('electron')
const mainWindow = new BrowserWindow()
desktopCapturer.getSources({ types: ['window', 'screen'] }).then(async sources => {
for (const source of sources) {
if (source.name === 'Electron') {
mainWindow.webContents.send('SET_SOURCE', source.id)
return
}
}
})
```
```javascript @ts-nocheck
// In the preload script.
const { ipcRenderer } = require('electron')
ipcRenderer.on('SET_SOURCE', async (event, sourceId) => {
try {
const stream = await navigator.mediaDevices.getUserMedia({
audio: false,
video: {
mandatory: {
chromeMediaSource: 'desktop',
chromeMediaSourceId: sourceId,
minWidth: 1280,
maxWidth: 1280,
minHeight: 720,
maxHeight: 720
}
}
})
handleStream(stream)
} catch (e) {
handleError(e)
}
})
function handleStream (stream) {
const video = document.querySelector('video')
video.srcObject = stream
video.onloadedmetadata = (e) => video.play()
}
function handleError (e) {
console.log(e)
}
```
To capture video from a source provided by `desktopCapturer` the constraints
passed to [`navigator.mediaDevices.getUserMedia`][] must include
`chromeMediaSource: 'desktop'`, and `audio: false`.
To capture both audio and video from the entire desktop the constraints passed
to [`navigator.mediaDevices.getUserMedia`][] must include `chromeMediaSource: 'desktop'`,
for both `audio` and `video`, but should not include a `chromeMediaSourceId` constraint.
```javascript
const constraints = {
audio: {
mandatory: {
chromeMediaSource: 'desktop'
}
},
video: {
mandatory: {
chromeMediaSource: 'desktop'
}
}
}
```
## Methods
The `desktopCapturer` module has the following methods:
### `desktopCapturer.getSources(options)`
* `options` Object
* `types` string[] - An array of strings that lists the types of desktop sources
to be captured, available types are `screen` and `window`.
* `thumbnailSize` [Size](structures/size.md) (optional) - The size that the media source thumbnail
should be scaled to. Default is `150` x `150`. Set width or height to 0 when you do not need
the thumbnails. This will save the processing time required for capturing the content of each
window and screen.
* `fetchWindowIcons` boolean (optional) - Set to true to enable fetching window icons. The default
value is false. When false the appIcon property of the sources return null. Same if a source has
the type screen.
Returns `Promise<DesktopCapturerSource[]>` - Resolves with an array of [`DesktopCapturerSource`](structures/desktop-capturer-source.md) objects, each `DesktopCapturerSource` represents a screen or an individual window that can be captured.
**Note** Capturing the screen contents requires user consent on macOS 10.15 Catalina or higher,
which can detected by [`systemPreferences.getMediaAccessStatus`][].
[`navigator.mediaDevices.getUserMedia`]: https://developer.mozilla.org/en/docs/Web/API/MediaDevices/getUserMedia
[`systemPreferences.getMediaAccessStatus`]: system-preferences.md#systempreferencesgetmediaaccessstatusmediatype-windows-macos
## Caveats
`navigator.mediaDevices.getUserMedia` does not work on macOS for audio capture due to a fundamental limitation whereby apps that want to access the system's audio require a [signed kernel extension](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/KernelExtensions/KernelExtensions.html). Chromium, and by extension Electron, does not provide this.
It is possible to circumvent this limitation by capturing system audio with another macOS app like Soundflower and passing it through a virtual audio input device. This virtual device can then be queried with `navigator.mediaDevices.getUserMedia`.

# nativeImage
> Create tray, dock, and application icons using PNG or JPG files.
Process: [Main](../glossary.md#main-process), [Renderer](../glossary.md#renderer-process)
In Electron, for the APIs that take images, you can pass either file paths or
`NativeImage` instances. An empty image will be used when `null` is passed.
For example, when creating a tray or setting a window's icon, you can pass an
image file path as a `string`:
```javascript
const { BrowserWindow, Tray } = require('electron')
const appIcon = new Tray('/Users/somebody/images/icon.png')
const win = new BrowserWindow({ icon: '/Users/somebody/images/window.png' })
console.log(appIcon, win)
```
Or read the image from the clipboard, which returns a `NativeImage`:
```javascript
const { clipboard, Tray } = require('electron')
const image = clipboard.readImage()
const appIcon = new Tray(image)
console.log(appIcon)
```
## Supported Formats
Currently `PNG` and `JPEG` image formats are supported. `PNG` is recommended
because of its support for transparency and lossless compression.
On Windows, you can also load `ICO` icons from file paths. For best visual
quality, it is recommended to include at least the following sizes in the:
* Small icon
* 16x16 (100% DPI scale)
* 20x20 (125% DPI scale)
* 24x24 (150% DPI scale)
* 32x32 (200% DPI scale)
* Large icon
* 32x32 (100% DPI scale)
* 40x40 (125% DPI scale)
* 48x48 (150% DPI scale)
* 64x64 (200% DPI scale)
* 256x256
Check the _Size requirements_ section in [this article][icons].
[icons]: https://learn.microsoft.com/en-us/windows/win32/uxguide/vis-icons
## High Resolution Image
On platforms that have high-DPI support such as Apple Retina displays, you can
append `@2x` after image's base filename to mark it as a high resolution image.
For example, if `icon.png` is a normal image that has standard resolution, then
`[email protected]` will be treated as a high resolution image that has double DPI
density.
If you want to support displays with different DPI densities at the same time,
you can put images with different sizes in the same folder and use the filename
without DPI suffixes. For example:
```plaintext
images/
├── icon.png
├── [email protected]
└── [email protected]
```
```javascript
const { Tray } = require('electron')
const appIcon = new Tray('/Users/somebody/images/icon.png')
console.log(appIcon)
```
The following suffixes for DPI are also supported:
* `@1x`
* `@1.25x`
* `@1.33x`
* `@1.4x`
* `@1.5x`
* `@1.8x`
* `@2x`
* `@2.5x`
* `@3x`
* `@4x`
* `@5x`
## Template Image
Template images consist of black and an alpha channel.
Template images are not intended to be used as standalone images and are usually
mixed with other content to create the desired final appearance.
The most common case is to use template images for a menu bar icon, so it can
adapt to both light and dark menu bars.
**Note:** Template image is only supported on macOS.
To mark an image as a template image, its filename should end with the word
`Template`. For example:
* `xxxTemplate.png`
* `[email protected]`
## Methods
The `nativeImage` module has the following methods, all of which return
an instance of the `NativeImage` class:
### `nativeImage.createEmpty()`
Returns `NativeImage`
Creates an empty `NativeImage` instance.
### `nativeImage.createThumbnailFromPath(path, size)` _macOS_ _Windows_
* `path` string - path to a file that we intend to construct a thumbnail out of.
* `size` [Size](structures/size.md) - the desired width and height (positive numbers) of the thumbnail.
Returns `Promise<NativeImage>` - fulfilled with the file's thumbnail preview image, which is a [NativeImage](native-image.md).
Note: The Windows implementation will ignore `size.height` and scale the height according to `size.width`.
### `nativeImage.createFromPath(path)`
* `path` string
Returns `NativeImage`
Creates a new `NativeImage` instance from a file located at `path`. This method
returns an empty image if the `path` does not exist, cannot be read, or is not
a valid image.
```javascript
const nativeImage = require('electron').nativeImage
const image = nativeImage.createFromPath('/Users/somebody/images/icon.png')
console.log(image)
```
### `nativeImage.createFromBitmap(buffer, options)`
* `buffer` [Buffer][buffer]
* `options` Object
* `width` Integer
* `height` Integer
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `NativeImage`
Creates a new `NativeImage` instance from `buffer` that contains the raw bitmap
pixel data returned by `toBitmap()`. The specific format is platform-dependent.
### `nativeImage.createFromBuffer(buffer[, options])`
* `buffer` [Buffer][buffer]
* `options` Object (optional)
* `width` Integer (optional) - Required for bitmap buffers.
* `height` Integer (optional) - Required for bitmap buffers.
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `NativeImage`
Creates a new `NativeImage` instance from `buffer`. Tries to decode as PNG or JPEG first.
### `nativeImage.createFromDataURL(dataURL)`
* `dataURL` string
Returns `NativeImage`
Creates a new `NativeImage` instance from `dataURL`.
### `nativeImage.createFromNamedImage(imageName[, hslShift])` _macOS_
* `imageName` string
* `hslShift` number[] (optional)
Returns `NativeImage`
Creates a new `NativeImage` instance from the NSImage that maps to the
given image name. See [`System Icons`](https://developer.apple.com/design/human-interface-guidelines/macos/icons-and-images/system-icons/)
for a list of possible values.
The `hslShift` is applied to the image with the following rules:
* `hsl_shift[0]` (hue): The absolute hue value for the image - 0 and 1 map
to 0 and 360 on the hue color wheel (red).
* `hsl_shift[1]` (saturation): A saturation shift for the image, with the
following key values:
0 = remove all color.
0.5 = leave unchanged.
1 = fully saturate the image.
* `hsl_shift[2]` (lightness): A lightness shift for the image, with the
following key values:
0 = remove all lightness (make all pixels black).
0.5 = leave unchanged.
1 = full lightness (make all pixels white).
This means that `[-1, 0, 1]` will make the image completely white and
`[-1, 1, 0]` will make the image completely black.
In some cases, the `NSImageName` doesn't match its string representation; one example of this is `NSFolderImageName`, whose string representation would actually be `NSFolder`. Therefore, you'll need to determine the correct string representation for your image before passing it in. This can be done with the following:
`echo -e '#import <Cocoa/Cocoa.h>\nint main() { NSLog(@"%@", SYSTEM_IMAGE_NAME); }' | clang -otest -x objective-c -framework Cocoa - && ./test`
where `SYSTEM_IMAGE_NAME` should be replaced with any value from [this list](https://developer.apple.com/documentation/appkit/nsimagename?language=objc).
## Class: NativeImage
> Natively wrap images such as tray, dock, and application icons.
Process: [Main](../glossary.md#main-process), [Renderer](../glossary.md#renderer-process)<br />
_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
### Instance Methods
The following methods are available on instances of the `NativeImage` class:
#### `image.toPNG([options])`
* `options` Object (optional)
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `Buffer` - A [Buffer][buffer] that contains the image's `PNG` encoded data.
#### `image.toJPEG(quality)`
* `quality` Integer - Between 0 - 100.
Returns `Buffer` - A [Buffer][buffer] that contains the image's `JPEG` encoded data.
#### `image.toBitmap([options])`
* `options` Object (optional)
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `Buffer` - A [Buffer][buffer] that contains a copy of the image's raw bitmap pixel
data.
#### `image.toDataURL([options])`
* `options` Object (optional)
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `string` - The data URL of the image.
#### `image.getBitmap([options])`
* `options` Object (optional)
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `Buffer` - A [Buffer][buffer] that contains the image's raw bitmap pixel data.
The difference between `getBitmap()` and `toBitmap()` is that `getBitmap()` does not
copy the bitmap data, so you have to use the returned Buffer immediately in
current event loop tick; otherwise the data might be changed or destroyed.
#### `image.getNativeHandle()` _macOS_
Returns `Buffer` - A [Buffer][buffer] that stores C pointer to underlying native handle of
the image. On macOS, a pointer to `NSImage` instance would be returned.
Notice that the returned pointer is a weak pointer to the underlying native
image instead of a copy, so you _must_ ensure that the associated
`nativeImage` instance is kept around.
#### `image.isEmpty()`
Returns `boolean` - Whether the image is empty.
#### `image.getSize([scaleFactor])`
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns [`Size`](structures/size.md).
If `scaleFactor` is passed, this will return the size corresponding to the image representation most closely matching the passed value.
#### `image.setTemplateImage(option)`
* `option` boolean
Marks the image as a template image.
#### `image.isTemplateImage()`
Returns `boolean` - Whether the image is a template image.
#### `image.crop(rect)`
* `rect` [Rectangle](structures/rectangle.md) - The area of the image to crop.
Returns `NativeImage` - The cropped image.
#### `image.resize(options)`
* `options` Object
* `width` Integer (optional) - Defaults to the image's width.
* `height` Integer (optional) - Defaults to the image's height.
* `quality` string (optional) - The desired quality of the resize image.
Possible values are `good`, `better`, or `best`. The default is `best`.
These values express a desired quality/speed tradeoff. They are translated
into an algorithm-specific method that depends on the capabilities
(CPU, GPU) of the underlying platform. It is possible for all three methods
to be mapped to the same algorithm on a given platform.
Returns `NativeImage` - The resized image.
If only the `height` or the `width` are specified then the current aspect ratio
will be preserved in the resized image.
#### `image.getAspectRatio([scaleFactor])`
* `scaleFactor` Number (optional) - Defaults to 1.0.
Returns `Number` - The image's aspect ratio.
If `scaleFactor` is passed, this will return the aspect ratio corresponding to the image representation most closely matching the passed value.
#### `image.getScaleFactors()`
Returns `Number[]` - An array of all scale factors corresponding to representations for a given nativeImage.
#### `image.addRepresentation(options)`
* `options` Object
* `scaleFactor` Number (optional) - The scale factor to add the image representation for.
* `width` Integer (optional) - Defaults to 0. Required if a bitmap buffer
is specified as `buffer`.
* `height` Integer (optional) - Defaults to 0. Required if a bitmap buffer
is specified as `buffer`.
* `buffer` Buffer (optional) - The buffer containing the raw image data.
* `dataURL` string (optional) - The data URL containing either a base 64
encoded PNG or JPEG image.
Add an image representation for a specific scale factor. This can be used
to explicitly add different scale factor representations to an image. This
can be called on empty images.
[buffer]: https://nodejs.org/api/buffer.html#buffer_class_buffer
### Instance Properties
#### `nativeImage.isMacTemplateImage` _macOS_
A `boolean` property that determines whether the image is considered a [template image](https://developer.apple.com/documentation/appkit/nsimage/1520017-template).
Please note that this property only has an effect on macOS.

[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

# session
> Manage browser sessions, cookies, cache, proxy settings, etc.
Process: [Main](../glossary.md#main-process)
The `session` module can be used to create new `Session` objects.
You can also access the `session` of existing pages by using the `session`
property of [`WebContents`](web-contents.md), or from the `session` module.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.loadURL('http://github.com')
const ses = win.webContents.session
console.log(ses.getUserAgent())
```
## Methods
The `session` module has the following methods:
### `session.fromPartition(partition[, options])`
* `partition` string
* `options` Object (optional)
* `cache` boolean - Whether to enable cache.
Returns `Session` - A session instance from `partition` string. When there is an existing
`Session` with the same `partition`, it will be returned; otherwise a new
`Session` instance will be created with `options`.
If `partition` starts with `persist:`, the page will use a persistent session
available to all pages in the app with the same `partition`. if there is no
`persist:` prefix, the page will use an in-memory session. If the `partition` is
empty then default session of the app will be returned.
To create a `Session` with `options`, you have to ensure the `Session` with the
`partition` has never been used before. There is no way to change the `options`
of an existing `Session` object.
### `session.fromPath(path[, options])`
* `path` string
* `options` Object (optional)
* `cache` boolean - Whether to enable cache.
Returns `Session` - A session instance from the absolute path as specified by the `path`
string. When there is an existing `Session` with the same absolute path, it
will be returned; otherwise a new `Session` instance will be created with `options`. The
call will throw an error if the path is not an absolute path. Additionally, an error will
be thrown if an empty string is provided.
To create a `Session` with `options`, you have to ensure the `Session` with the
`path` has never been used before. There is no way to change the `options`
of an existing `Session` object.
## Properties
The `session` module has the following properties:
### `session.defaultSession`
A `Session` object, the default session object of the app.
## Class: Session
> Get and set properties of a session.
Process: [Main](../glossary.md#main-process)<br />
_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
You can create a `Session` object in the `session` module:
```javascript
const { session } = require('electron')
const ses = session.fromPartition('persist:name')
console.log(ses.getUserAgent())
```
### Instance Events
The following events are available on instances of `Session`:
#### Event: 'will-download'
Returns:
* `event` Event
* `item` [DownloadItem](download-item.md)
* `webContents` [WebContents](web-contents.md)
Emitted when Electron is about to download `item` in `webContents`.
Calling `event.preventDefault()` will cancel the download and `item` will not be
available from next tick of the process.
```javascript @ts-expect-error=[4]
const { session } = require('electron')
session.defaultSession.on('will-download', (event, item, webContents) => {
event.preventDefault()
require('got')(item.getURL()).then((response) => {
require('fs').writeFileSync('/somewhere', response.body)
})
})
```
#### Event: 'extension-loaded'
Returns:
* `event` Event
* `extension` [Extension](structures/extension.md)

Emitted after an extension is unloaded. This occurs when
`Session.removeExtension` is called.
#### Event: 'extension-ready'
Returns:
* `event` Event
* `extension` [Extension](structures/extension.md)
Emitted after an extension is loaded and all necessary browser state is
initialized to support the start of the extension's background page.
#### Event: 'preconnect'
Returns:
* `event` Event
* `preconnectUrl` string - The URL being requested for preconnection by the
renderer.

Emitted when a hunspell dictionary file has been successfully downloaded
#### Event: 'spellcheck-dictionary-download-failure'
Returns:
* `event` Event
* `languageCode` string - The language code of the dictionary file
Emitted when a hunspell dictionary file download fails. For details
on the failure you should collect a netlog and inspect the download

`navigator.hid.requestDevice` is made. `callback` should be called with
`deviceId` to be selected; passing no arguments to `callback` will
cancel the request. Additionally, permissioning on `navigator.hid` can
be further managed by using [`ses.setPermissionCheckHandler(handler)`](#sessetpermissioncheckhandlerhandler)
and [`ses.setDevicePermissionHandler(handler)`](#sessetdevicepermissionhandlerhandler).
```javascript @ts-type={fetchGrantedDevices:()=>(Array<Electron.DevicePermissionHandlerHandlerDetails['device']>)}
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow()
win.webContents.session.setPermissionCheckHandler((webContents, permission, requestingOrigin, details) => {
if (permission === 'hid') {
// Add logic here to determine if permission should be given to allow HID selection
return true
}
return false
})
// Optionally, retrieve previously persisted devices from a persistent store
const grantedDevices = fetchGrantedDevices()

Emitted when a serial port needs to be selected when a call to
`navigator.serial.requestPort` is made. `callback` should be called with
`portId` to be selected, passing an empty string to `callback` will
cancel the request. Additionally, permissioning on `navigator.serial` can
be managed by using [ses.setPermissionCheckHandler(handler)](#sessetpermissioncheckhandlerhandler)
with the `serial` permission.
```javascript @ts-type={fetchGrantedDevices:()=>(Array<Electron.DevicePermissionHandlerHandlerDetails['device']>)}
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow({

### Instance Methods
The following methods are available on instances of `Session`:
#### `ses.getCacheSize()`
Returns `Promise<Integer>` - the session's current cache size, in bytes.
#### `ses.clearCache()`
Returns `Promise<void>` - resolves when the cache clear operation is complete.
Clears the session’s HTTP cache.
#### `ses.clearStorageData([options])`
* `options` Object (optional)
* `origin` string (optional) - Should follow `window.location.origin`’s representation
`scheme://host:port`.
* `storages` string[] (optional) - The types of storages to clear, can contain:
`cookies`, `filesystem`, `indexdb`, `localstorage`,
`shadercache`, `websql`, `serviceworkers`, `cachestorage`. If not
specified, clear all storage types.
* `quotas` string[] (optional) - The types of quotas to clear, can contain:
`temporary`, `syncable`. If not specified, clear all quotas.
Returns `Promise<void>` - resolves when the storage data has been cleared.
#### `ses.flushStorageData()`
Writes any unwritten DOMStorage data to disk.
#### `ses.setProxy(config)`
* `config` Object
* `mode` string (optional) - The proxy mode. Should be one of `direct`,
`auto_detect`, `pac_script`, `fixed_servers` or `system`. If it's
unspecified, it will be automatically determined based on other specified
options.
* `direct`
In direct mode all connections are created directly, without any proxy involved.
* `auto_detect`
In auto_detect mode the proxy configuration is determined by a PAC script that can
be downloaded at http://wpad/wpad.dat.
* `pac_script`
In pac_script mode the proxy configuration is determined by a PAC script that is
retrieved from the URL specified in the `pacScript`. This is the default mode
if `pacScript` is specified.
* `fixed_servers`
In fixed_servers mode the proxy configuration is specified in `proxyRules`.
This is the default mode if `proxyRules` is specified.
* `system`
In system mode the proxy configuration is taken from the operating system.
Note that the system mode is different from setting no proxy configuration.
In the latter case, Electron falls back to the system settings
only if no command-line options influence the proxy configuration.
* `pacScript` string (optional) - The URL associated with the PAC file.
* `proxyRules` string (optional) - Rules indicating which proxies to use.
* `proxyBypassRules` string (optional) - Rules indicating which URLs should
bypass the proxy settings.
Returns `Promise<void>` - Resolves when the proxy setting process is complete.
Sets the proxy settings.
When `mode` is unspecified, `pacScript` and `proxyRules` are provided together, the `proxyRules`
option is ignored and `pacScript` configuration is applied.
You may need `ses.closeAllConnections` to close currently in flight connections to prevent
pooled sockets using previous proxy from being reused by future requests.
The `proxyRules` has to follow the rules below:
```sh
proxyRules = schemeProxies[";"<schemeProxies>]
schemeProxies = [<urlScheme>"="]<proxyURIList>
urlScheme = "http" | "https" | "ftp" | "socks"
proxyURIList = <proxyURL>[","<proxyURIList>]
proxyURL = [<proxyScheme>"://"]<proxyHost>[":"<proxyPort>]
```
For example:
* `http=foopy:80;ftp=foopy2` - Use HTTP proxy `foopy:80` for `http://` URLs, and
HTTP proxy `foopy2:80` for `ftp://` URLs.
* `foopy:80` - Use HTTP proxy `foopy:80` for all URLs.
* `foopy:80,bar,direct://` - Use HTTP proxy `foopy:80` for all URLs, failing
over to `bar` if `foopy:80` is unavailable, and after that using no proxy.
* `socks4://foopy` - Use SOCKS v4 proxy `foopy:1080` for all URLs.
* `http=foopy,socks5://bar.com` - Use HTTP proxy `foopy` for http URLs, and fail
over to the SOCKS5 proxy `bar.com` if `foopy` is unavailable.
* `http=foopy,direct://` - Use HTTP proxy `foopy` for http URLs, and use no
proxy if `foopy` is unavailable.
* `http=foopy;socks=foopy2` - Use HTTP proxy `foopy` for http URLs, and use
`socks4://foopy2` for all other URLs.
The `proxyBypassRules` is a comma separated list of rules described below:
* `[ URL_SCHEME "://" ] HOSTNAME_PATTERN [ ":" <port> ]`
Match all hostnames that match the pattern HOSTNAME_PATTERN.
Examples:
"foobar.com", "\*foobar.com", "\*.foobar.com", "\*foobar.com:99",
"https://x.\*.y.com:99"
* `"." HOSTNAME_SUFFIX_PATTERN [ ":" PORT ]`
Match a particular domain suffix.
Examples:
".google.com", ".com", "http://.google.com"
* `[ SCHEME "://" ] IP_LITERAL [ ":" PORT ]`
Match URLs which are IP address literals.
Examples:
"127.0.1", "\[0:0::1]", "\[::1]", "http://\[::1]:99"
* `IP_LITERAL "/" PREFIX_LENGTH_IN_BITS`
Match any URL that is to an IP literal that falls between the
given range. IP range is specified using CIDR notation.
Examples:
"192.168.1.1/16", "fefe:13::abc/33".
* `<local>`
Match local addresses. The meaning of `<local>` is whether the
host matches one of: "127.0.0.1", "::1", "localhost".
#### `ses.resolveHost(host, [options])`
* `host` string - Hostname to resolve.
* `options` Object (optional)
* `queryType` string (optional) - Requested DNS query type. If unspecified,
resolver will pick A or AAAA (or both) based on IPv4/IPv6 settings:
* `A` - Fetch only A records
* `AAAA` - Fetch only AAAA records.
* `source` string (optional) - The source to use for resolved addresses.
Default allows the resolver to pick an appropriate source. Only affects use
of big external sources (e.g. calling the system for resolution or using
DNS). Even if a source is specified, results can still come from cache,
resolving "localhost" or IP literals, etc. One of the following values:
* `any` (default) - Resolver will pick an appropriate source. Results could
come from DNS, MulticastDNS, HOSTS file, etc
* `system` - Results will only be retrieved from the system or OS, e.g. via
the `getaddrinfo()` system call
* `dns` - Results will only come from DNS queries
* `mdns` - Results will only come from Multicast DNS queries
* `localOnly` - No external sources will be used. Results will only come
from fast local sources that are available no matter the source setting,
e.g. cache, hosts file, IP literal resolution, etc.
* `cacheUsage` string (optional) - Indicates what DNS cache entries, if any,
can be used to provide a response. One of the following values:
* `allowed` (default) - Results may come from the host cache if non-stale
* `staleAllowed` - Results may come from the host cache even if stale (by
expiration or network changes)
* `disallowed` - Results will not come from the host cache.
* `secureDnsPolicy` string (optional) - Controls the resolver's Secure DNS
behavior for this request. One of the following values:
* `allow` (default)
* `disable`
Returns [`Promise<ResolvedHost>`](structures/resolved-host.md) - Resolves with the resolved IP addresses for the `host`.
#### `ses.resolveProxy(url)`
* `url` URL
Returns `Promise<string>` - Resolves with the proxy information for `url`.
#### `ses.forceReloadProxyConfig()`
Returns `Promise<void>` - Resolves when the all internal states of proxy service is reset and the latest proxy configuration is reapplied if it's already available. The pac script will be fetched from `pacScript` again if the proxy mode is `pac_script`.
#### `ses.setDownloadPath(path)`
* `path` string - The download location.
Sets download saving directory. By default, the download directory will be the
`Downloads` under the respective app folder.
#### `ses.enableNetworkEmulation(options)`
* `options` Object
* `offline` boolean (optional) - Whether to emulate network outage. Defaults
to false.
* `latency` Double (optional) - RTT in ms. Defaults to 0 which will disable
latency throttling.
* `downloadThroughput` Double (optional) - Download rate in Bps. Defaults to 0
which will disable download throttling.
* `uploadThroughput` Double (optional) - Upload rate in Bps. Defaults to 0
which will disable upload throttling.
Emulates network with the given configuration for the `session`.
```javascript
const win = new BrowserWindow()
// To emulate a GPRS connection with 50kbps throughput and 500 ms latency.
win.webContents.session.enableNetworkEmulation({
latency: 500,
downloadThroughput: 6400,
uploadThroughput: 6400
})
// To emulate a network outage.
win.webContents.session.enableNetworkEmulation({ offline: true })
```
#### `ses.preconnect(options)`
* `options` Object
* `url` string - URL for preconnect. Only the origin is relevant for opening the socket.
* `numSockets` number (optional) - number of sockets to preconnect. Must be between 1 and 6. Defaults to 1.
Preconnects the given number of sockets to an origin.
#### `ses.closeAllConnections()`
Returns `Promise<void>` - Resolves when all connections are closed.
**Note:** It will terminate / fail all requests currently in flight.
#### `ses.fetch(input[, init])`
* `input` string | [GlobalRequest](https://nodejs.org/api/globals.html#request)
* `init` [RequestInit](https://developer.mozilla.org/en-US/docs/Web/API/fetch#options) (optional)
Returns `Promise<GlobalResponse>` - see [Response](https://developer.mozilla.org/en-US/docs/Web/API/Response).
Sends a request, similarly to how `fetch()` works in the renderer, using
Chrome's network stack. This differs from Node's `fetch()`, which uses
Node.js's HTTP stack.
Example:
```js
async function example () {
const response = await net.fetch('https://my.app')
if (response.ok) {
const body = await response.json()
// ... use the result.
}
}
```
See also [`net.fetch()`](net.md#netfetchinput-init), a convenience method which
issues requests from the [default session](#sessiondefaultsession).
See the MDN documentation for
[`fetch()`](https://developer.mozilla.org/en-US/docs/Web/API/fetch) for more
details.
Limitations:
* `net.fetch()` does not support the `data:` or `blob:` schemes.
* The value of the `integrity` option is ignored.
* The `.type` and `.url` values of the returned `Response` object are
incorrect.
By default, requests made with `net.fetch` can be made to [custom
protocols](protocol.md) as well as `file:`, and will trigger
[webRequest](web-request.md) handlers if present. When the non-standard
`bypassCustomProtocolHandlers` option is set in RequestInit, custom protocol
handlers will not be called for this request. This allows forwarding an
intercepted request to the built-in handler. [webRequest](web-request.md)
handlers will still be triggered when bypassing custom protocols.
```js
protocol.handle('https', (req) => {
if (req.url === 'https://my-app.com') {
return new Response('<body>my app</body>')
} else {
return net.fetch(req, { bypassCustomProtocolHandlers: true })
}
})
```
#### `ses.disableNetworkEmulation()`
Disables any network emulation already active for the `session`. Resets to
the original network configuration.
#### `ses.setCertificateVerifyProc(proc)`
* `proc` Function | null
* `request` Object
* `hostname` string
* `certificate` [Certificate](structures/certificate.md)
* `validatedCertificate` [Certificate](structures/certificate.md)
* `isIssuedByKnownRoot` boolean - `true` if Chromium recognises the root CA as a standard root. If it isn't then it's probably the case that this certificate was generated by a MITM proxy whose root has been installed locally (for example, by a corporate proxy). This should not be trusted if the `verificationResult` is not `OK`.
* `verificationResult` string - `OK` if the certificate is trusted, otherwise an error like `CERT_REVOKED`.
* `errorCode` Integer - Error code.
* `callback` Function
* `verificationResult` Integer - Value can be one of certificate error codes
from [here](https://source.chromium.org/chromium/chromium/src/+/main:net/base/net_error_list.h).
Apart from the certificate error codes, the following special codes can be used.
* `0` - Indicates success and disables Certificate Transparency verification.
* `-2` - Indicates failure.
* `-3` - Uses the verification result from chromium.
Sets the certificate verify proc for `session`, the `proc` will be called with
`proc(request, callback)` whenever a server certificate
verification is requested. Calling `callback(0)` accepts the certificate,
calling `callback(-2)` rejects it.
Calling `setCertificateVerifyProc(null)` will revert back to default certificate
verify proc.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.webContents.session.setCertificateVerifyProc((request, callback) => {
const { hostname } = request
if (hostname === 'github.com') {
callback(0)
} else {
callback(-2)
}
})
```
> **NOTE:** The result of this procedure is cached by the network service.

Sets the handler which can be used to respond to permission requests for the `session`.
Calling `callback(true)` will allow the permission and `callback(false)` will reject it.
To clear the handler, call `setPermissionRequestHandler(null)`. Please note that
you must also implement `setPermissionCheckHandler` to get complete permission handling.
Most web APIs do a permission check and then make a permission request if the check is denied.
```javascript
const { session } = require('electron')
session.fromPartition('some-partition').setPermissionRequestHandler((webContents, permission, callback) => {
if (webContents.getURL() === 'some-host' && permission === 'notifications') {
return callback(false) // denied.
}
callback(true)
})
```
#### `ses.setPermissionCheckHandler(handler)`
* `handler` Function\<boolean> | null
* `webContents` ([WebContents](web-contents.md) | null) - WebContents checking the permission. Please note that if the request comes from a subframe you should use `requestingUrl` to check the request origin. All cross origin sub frames making permission checks will pass a `null` webContents to this handler, while certain other permission checks such as `notifications` checks will always pass `null`. You should use `embeddingOrigin` and `requestingOrigin` to determine what origin the owning frame and the requesting frame are on respectively.
* `permission` string - Type of permission check.

* `serial` - Read from and write to serial devices with the [Web Serial API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Serial_API).
* `usb` - Expose non-standard Universal Serial Bus (USB) compatible devices services to the web with the [WebUSB API](https://developer.mozilla.org/en-US/docs/Web/API/WebUSB_API).
* `requestingOrigin` string - The origin URL of the permission check
* `details` Object - Some properties are only available on certain permission types.
* `embeddingOrigin` string (optional) - The origin of the frame embedding the frame that made the permission check. Only set for cross-origin sub frames making permission checks.
* `securityOrigin` string (optional) - The security origin of the `media` check.
* `mediaType` string (optional) - The type of media access being requested, can be `video`,
`audio` or `unknown`
* `requestingUrl` string (optional) - The last URL the requesting frame loaded. This is not provided for cross-origin sub frames making permission checks.
* `isMainFrame` boolean - Whether the frame making the request is the main frame
Sets the handler which can be used to respond to permission checks for the `session`.
Returning `true` will allow the permission and `false` will reject it. Please note that
you must also implement `setPermissionRequestHandler` to get complete permission handling.
Most web APIs do a permission check and then make a permission request if the check is denied.
To clear the handler, call `setPermissionCheckHandler(null)`.
```javascript
const { session } = require('electron')
const url = require('url')
session.fromPartition('some-partition').setPermissionCheckHandler((webContents, permission, requestingOrigin) => {
if (new URL(requestingOrigin).hostname === 'some-host' && permission === 'notifications') {
return true // granted
}
return false // denied
})
```
#### `ses.setDisplayMediaRequestHandler(handler)`
* `handler` Function | null
* `request` Object
* `frame` [WebFrameMain](web-frame-main.md) - Frame that is requesting access to media.
* `securityOrigin` String - Origin of the page making the request.
* `videoRequested` Boolean - true if the web content requested a video stream.
* `audioRequested` Boolean - true if the web content requested an audio stream.
* `userGesture` Boolean - Whether a user gesture was active when this request was triggered.
* `callback` Function
* `streams` Object
* `video` Object | [WebFrameMain](web-frame-main.md) (optional)
* `id` String - The id of the stream being granted. This will usually
come from a [DesktopCapturerSource](structures/desktop-capturer-source.md)
object.
* `name` String - The name of the stream being granted. This will
usually come from a [DesktopCapturerSource](structures/desktop-capturer-source.md)
object.
* `audio` String | [WebFrameMain](web-frame-main.md) (optional) - If
a string is specified, can be `loopback` or `loopbackWithMute`.
Specifying a loopback device will capture system audio, and is
currently only supported on Windows. If a WebFrameMain is specified,
will capture audio from that frame.
* `enableLocalEcho` Boolean (optional) - If `audio` is a [WebFrameMain](web-frame-main.md)
and this is set to `true`, then local playback of audio will not be muted (e.g. using `MediaRecorder`
to record `WebFrameMain` with this flag set to `true` will allow audio to pass through to the speakers
while recording). Default is `false`.
This handler will be called when web content requests access to display media
via the `navigator.mediaDevices.getDisplayMedia` API. Use the
[desktopCapturer](desktop-capturer.md) API to choose which stream(s) to grant
access to.
```javascript
const { session, desktopCapturer } = require('electron')
session.defaultSession.setDisplayMediaRequestHandler((request, callback) => {
desktopCapturer.getSources({ types: ['screen'] }).then((sources) => {
// Grant access to the first screen found.
callback({ video: sources[0] })
})
})
```
Passing a [WebFrameMain](web-frame-main.md) object as a video or audio stream
will capture the video or audio stream from that frame.
```javascript
const { session } = require('electron')
session.defaultSession.setDisplayMediaRequestHandler((request, callback) => {
// Allow the tab to capture itself.
callback({ video: request.frame })
})
```
Passing `null` instead of a function resets the handler to its default state.
#### `ses.setDevicePermissionHandler(handler)`
* `handler` Function\<boolean> | null
* `details` Object
* `deviceType` string - The type of device that permission is being requested on, can be `hid`, `serial`, or `usb`.
* `origin` string - The origin URL of the device permission check.
* `device` [HIDDevice](structures/hid-device.md) | [SerialPort](structures/serial-port.md) | [USBDevice](structures/usb-device.md) - the device that permission is being requested for.
Sets the handler which can be used to respond to device permission checks for the `session`.
Returning `true` will allow the device to be permitted and `false` will reject it.
To clear the handler, call `setDevicePermissionHandler(null)`.
This handler can be used to provide default permissioning to devices without first calling for permission
to devices (eg via `navigator.hid.requestDevice`). If this handler is not defined, the default device
permissions as granted through device selection (eg via `navigator.hid.requestDevice`) will be used.
Additionally, the default behavior of Electron is to store granted device permision in memory.
If longer term storage is needed, a developer can store granted device
permissions (eg when handling the `select-hid-device` event) and then read from that storage with `setDevicePermissionHandler`.
```javascript @ts-type={fetchGrantedDevices:()=>(Array<Electron.DevicePermissionHandlerHandlerDetails['device']>)}
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow()
win.webContents.session.setPermissionCheckHandler((webContents, permission, requestingOrigin, details) => {
if (permission === 'hid') {
// Add logic here to determine if permission should be given to allow HID selection
return true
} else if (permission === 'serial') {
// Add logic here to determine if permission should be given to allow serial port selection
} else if (permission === 'usb') {
// Add logic here to determine if permission should be given to allow USB device selection
}
return false
})
// Optionally, retrieve previously persisted devices from a persistent store
const grantedDevices = fetchGrantedDevices()
win.webContents.session.setDevicePermissionHandler((details) => {
if (new URL(details.origin).hostname === 'some-host' && details.deviceType === 'hid') {
if (details.device.vendorId === 123 && details.device.productId === 345) {
// Always allow this type of device (this allows skipping the call to `navigator.hid.requestDevice` first)
return true
}
// Search through the list of devices that have previously been granted permission
return grantedDevices.some((grantedDevice) => {
return grantedDevice.vendorId === details.device.vendorId &&
grantedDevice.productId === details.device.productId &&
grantedDevice.serialNumber && grantedDevice.serialNumber === details.device.serialNumber
})
} else if (details.deviceType === 'serial') {
if (details.device.vendorId === 123 && details.device.productId === 345) {
// Always allow this type of device (this allows skipping the call to `navigator.hid.requestDevice` first)
return true
}
}
return false
})
win.webContents.session.on('select-hid-device', (event, details, callback) => {
event.preventDefault()
const selectedDevice = details.deviceList.find((device) => {
return device.vendorId === 9025 && device.productId === 67
})
callback(selectedDevice?.deviceId)
})
})
```
#### `ses.setUSBProtectedClassesHandler(handler)`
* `handler` Function\<string[]> | null
* `details` Object
* `protectedClasses` string[] - The current list of protected USB classes. Possible class values are:
* `audio`
* `audio-video`
* `hid`
* `mass-storage`
* `smart-card`
* `video`
* `wireless`
Sets the handler which can be used to override which [USB classes are protected](https://wicg.github.io/webusb/#usbinterface-interface).
The return value for the handler is a string array of USB classes which should be considered protected (eg not available in the renderer). Valid values for the array are:
* `audio`
* `audio-video`
* `hid`
* `mass-storage`
* `smart-card`
* `video`
* `wireless`
Returning an empty string array from the handler will allow all USB classes; returning the passed in array will maintain the default list of protected USB classes (this is also the default behavior if a handler is not defined).
To clear the handler, call `setUSBProtectedClassesHandler(null)`.
```javascript
const { app, BrowserWindow } = require('electron')
let win = null
app.whenReady().then(() => {
win = new BrowserWindow()
win.webContents.session.setUSBProtectedClassesHandler((details) => {
// Allow all classes:
// return []
// Keep the current set of protected classes:
// return details.protectedClasses
// Selectively remove classes:
return details.protectedClasses.filter((usbClass) => {
// Exclude classes except for audio classes
return usbClass.indexOf('audio') === -1
})
})
})
```
#### `ses.setBluetoothPairingHandler(handler)` _Windows_ _Linux_
* `handler` Function | null
* `details` Object
* `deviceId` string
* `pairingKind` string - The type of pairing prompt being requested.
One of the following values:
* `confirm`
This prompt is requesting confirmation that the Bluetooth device should
be paired.
* `confirmPin`
This prompt is requesting confirmation that the provided PIN matches the
pin displayed on the device.
* `providePin`
This prompt is requesting that a pin be provided for the device.
* `frame` [WebFrameMain](web-frame-main.md)
* `pin` string (optional) - The pin value to verify if `pairingKind` is `confirmPin`.
* `callback` Function
* `response` Object
* `confirmed` boolean - `false` should be passed in if the dialog is canceled.
If the `pairingKind` is `confirm` or `confirmPin`, this value should indicate
if the pairing is confirmed. If the `pairingKind` is `providePin` the value
should be `true` when a value is provided.
* `pin` string | null (optional) - When the `pairingKind` is `providePin`
this value should be the required pin for the Bluetooth device.
Sets a handler to respond to Bluetooth pairing requests. This handler
allows developers to handle devices that require additional validation
before pairing. When a handler is not defined, any pairing on Linux or Windows
that requires additional validation will be automatically cancelled.
macOS does not require a handler because macOS handles the pairing
automatically. To clear the handler, call `setBluetoothPairingHandler(null)`.
```javascript
const { app, BrowserWindow, session } = require('electron')
const path = require('path')
function createWindow () {
let bluetoothPinCallback = null
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, 'preload.js')
}
})
mainWindow.webContents.session.setBluetoothPairingHandler((details, callback) => {
bluetoothPinCallback = callback
// Send a IPC message to the renderer to prompt the user to confirm the pairing.
// Note that this will require logic in the renderer to handle this message and
// display a prompt to the user.
mainWindow.webContents.send('bluetooth-pairing-request', details)
})
// Listen for an IPC message from the renderer to get the response for the Bluetooth pairing.
mainWindow.webContents.ipc.on('bluetooth-pairing-response', (event, response) => {
bluetoothPinCallback(response)
})
}
app.whenReady().then(() => {
createWindow()
})
```
#### `ses.clearHostResolverCache()`
Returns `Promise<void>` - Resolves when the operation is complete.
Clears the host resolver cache.
#### `ses.allowNTLMCredentialsForDomains(domains)`
* `domains` string - A comma-separated list of servers for which
integrated authentication is enabled.
Dynamically sets whether to always send credentials for HTTP NTLM or Negotiate
authentication.
```javascript
const { session } = require('electron')
// consider any url ending with `example.com`, `foobar.com`, `baz`
// for integrated authentication.
session.defaultSession.allowNTLMCredentialsForDomains('*example.com, *foobar.com, *baz')
// consider all urls for integrated authentication.
session.defaultSession.allowNTLMCredentialsForDomains('*')
```
#### `ses.setUserAgent(userAgent[, acceptLanguages])`
* `userAgent` string
* `acceptLanguages` string (optional)
Overrides the `userAgent` and `acceptLanguages` for this session.
The `acceptLanguages` must a comma separated ordered list of language codes, for
example `"en-US,fr,de,ko,zh-CN,ja"`.
This doesn't affect existing `WebContents`, and each `WebContents` can use
`webContents.setUserAgent` to override the session-wide user agent.
#### `ses.isPersistent()`
Returns `boolean` - Whether or not this session is a persistent one. The default
`webContents` session of a `BrowserWindow` is persistent. When creating a session
from a partition, session prefixed with `persist:` will be persistent, while others
will be temporary.
#### `ses.getUserAgent()`
Returns `string` - The user agent for this session.
#### `ses.setSSLConfig(config)`
* `config` Object
* `minVersion` string (optional) - Can be `tls1`, `tls1.1`, `tls1.2` or `tls1.3`. The
minimum SSL version to allow when connecting to remote servers. Defaults to
`tls1`.
* `maxVersion` string (optional) - Can be `tls1.2` or `tls1.3`. The maximum SSL version
to allow when connecting to remote servers. Defaults to `tls1.3`.
* `disabledCipherSuites` Integer[] (optional) - List of cipher suites which
should be explicitly prevented from being used in addition to those
disabled by the net built-in policy.
Supported literal forms: 0xAABB, where AA is `cipher_suite[0]` and BB is
`cipher_suite[1]`, as defined in RFC 2246, Section 7.4.1.2. Unrecognized but
parsable cipher suites in this form will not return an error.
Ex: To disable TLS_RSA_WITH_RC4_128_MD5, specify 0x0004, while to
disable TLS_ECDH_ECDSA_WITH_RC4_128_SHA, specify 0xC002.
Note that TLSv1.3 ciphers cannot be disabled using this mechanism.
Sets the SSL configuration for the session. All subsequent network requests
will use the new configuration. Existing network connections (such as WebSocket
connections) will not be terminated, but old sockets in the pool will not be
reused for new connections.
#### `ses.getBlobData(identifier)`
* `identifier` string - Valid UUID.
Returns `Promise<Buffer>` - resolves with blob data.
#### `ses.downloadURL(url[, options])`
* `url` string
* `options` Object (optional)
* `headers` Record<string, string> (optional) - HTTP request headers.
Initiates a download of the resource at `url`.
The API will generate a [DownloadItem](download-item.md) that can be accessed
with the [will-download](#event-will-download) event.
**Note:** This does not perform any security checks that relate to a page's origin,
unlike [`webContents.downloadURL`](web-contents.md#contentsdownloadurlurl).
#### `ses.createInterruptedDownload(options)`
* `options` Object
* `path` string - Absolute path of the download.
* `urlChain` string[] - Complete URL chain for the download.
* `mimeType` string (optional)
* `offset` Integer - Start range for the download.
* `length` Integer - Total length of the download.
* `lastModified` string (optional) - Last-Modified header value.
* `eTag` string (optional) - ETag header value.
* `startTime` Double (optional) - Time when download was started in
number of seconds since UNIX epoch.
Allows resuming `cancelled` or `interrupted` downloads from previous `Session`.
The API will generate a [DownloadItem](download-item.md) that can be accessed with the [will-download](#event-will-download)
event. The [DownloadItem](download-item.md) will not have any `WebContents` associated with it and
the initial state will be `interrupted`. The download will start only when the
`resume` API is called on the [DownloadItem](download-item.md).
#### `ses.clearAuthCache()`
Returns `Promise<void>` - resolves when the session’s HTTP authentication cache has been cleared.
#### `ses.setPreloads(preloads)`
* `preloads` string[] - An array of absolute path to preload scripts
Adds scripts that will be executed on ALL web contents that are associated with
this session just before normal `preload` scripts run.
#### `ses.getPreloads()`
Returns `string[]` an array of paths to preload scripts that have been
registered.
#### `ses.setCodeCachePath(path)`
* `path` String - Absolute path to store the v8 generated JS code cache from the renderer.
Sets the directory to store the generated JS [code cache](https://v8.dev/blog/code-caching-for-devs) for this session. The directory is not required to be created by the user before this call, the runtime will create if it does not exist otherwise will use the existing directory. If directory cannot be created, then code cache will not be used and all operations related to code cache will fail silently inside the runtime. By default, the directory will be `Code Cache` under the
respective user data folder.
#### `ses.clearCodeCaches(options)`
* `options` Object
* `urls` String[] (optional) - An array of url corresponding to the resource whose generated code cache needs to be removed. If the list is empty then all entries in the cache directory will be removed.
Returns `Promise<void>` - resolves when the code cache clear operation is complete.
#### `ses.setSpellCheckerEnabled(enable)`
* `enable` boolean
Sets whether to enable the builtin spell checker.
#### `ses.isSpellCheckerEnabled()`
Returns `boolean` - Whether the builtin spell checker is enabled.
#### `ses.setSpellCheckerLanguages(languages)`
* `languages` string[] - An array of language codes to enable the spellchecker for.
The built in spellchecker does not automatically detect what language a user is typing in. In order for the
spell checker to correctly check their words you must call this API with an array of language codes. You can
get the list of supported language codes with the `ses.availableSpellCheckerLanguages` property.
**Note:** On macOS the OS spellchecker is used and will detect your language automatically. This API is a no-op on macOS.
#### `ses.getSpellCheckerLanguages()`
Returns `string[]` - An array of language codes the spellchecker is enabled for. If this list is empty the spellchecker
will fallback to using `en-US`. By default on launch if this setting is an empty list Electron will try to populate this
setting with the current OS locale. This setting is persisted across restarts.
**Note:** On macOS the OS spellchecker is used and has its own list of languages. On macOS, this API will return whichever languages have been configured by the OS.
#### `ses.setSpellCheckerDictionaryDownloadURL(url)`
* `url` string - A base URL for Electron to download hunspell dictionaries from.
By default Electron will download hunspell dictionaries from the Chromium CDN. If you want to override this
behavior you can use this API to point the dictionary downloader at your own hosted version of the hunspell
dictionaries. We publish a `hunspell_dictionaries.zip` file with each release which contains the files you need
to host here.
The file server must be **case insensitive**. If you cannot do this, you must upload each file twice: once with
the case it has in the ZIP file and once with the filename as all lowercase.
If the files present in `hunspell_dictionaries.zip` are available at `https://example.com/dictionaries/language-code.bdic`
then you should call this api with `ses.setSpellCheckerDictionaryDownloadURL('https://example.com/dictionaries/')`. Please
note the trailing slash. The URL to the dictionaries is formed as `${url}${filename}`.
**Note:** On macOS the OS spellchecker is used and therefore we do not download any dictionary files. This API is a no-op on macOS.
#### `ses.listWordsInSpellCheckerDictionary()`
Returns `Promise<string[]>` - An array of all words in app's custom dictionary.
Resolves when the full dictionary is loaded from disk.
#### `ses.addWordToSpellCheckerDictionary(word)`
* `word` string - The word you want to add to the dictionary
Returns `boolean` - Whether the word was successfully written to the custom dictionary. This API
will not work on non-persistent (in-memory) sessions.
**Note:** On macOS and Windows 10 this word will be written to the OS custom dictionary as well
#### `ses.removeWordFromSpellCheckerDictionary(word)`
* `word` string - The word you want to remove from the dictionary
Returns `boolean` - Whether the word was successfully removed from the custom dictionary. This API
will not work on non-persistent (in-memory) sessions.
**Note:** On macOS and Windows 10 this word will be removed from the OS custom dictionary as well
#### `ses.loadExtension(path[, options])`
* `path` string - Path to a directory containing an unpacked Chrome extension
* `options` Object (optional)
* `allowFileAccess` boolean - Whether to allow the extension to read local files over `file://`
protocol and inject content scripts into `file://` pages. This is required e.g. for loading
devtools extensions on `file://` URLs. Defaults to false.
Returns `Promise<Extension>` - resolves when the extension is loaded.
This method will raise an exception if the extension could not be loaded. If
there are warnings when installing the extension (e.g. if the extension
requests an API that Electron does not support) then they will be logged to the
console.
Note that Electron does not support the full range of Chrome extensions APIs.
See [Supported Extensions APIs](extensions.md#supported-extensions-apis) for
more details on what is supported.
Note that in previous versions of Electron, extensions that were loaded would
be remembered for future runs of the application. This is no longer the case:
`loadExtension` must be called on every boot of your app if you want the
extension to be loaded.
```js
const { app, session } = require('electron')
const path = require('path')
app.whenReady().then(async () => {
await session.defaultSession.loadExtension(
path.join(__dirname, 'react-devtools'),
// allowFileAccess is required to load the devtools extension on file:// URLs.
{ allowFileAccess: true }
)
// Note that in order to use the React DevTools extension, you'll need to
// download and unzip a copy of the extension.
})
```
This API does not support loading packed (.crx) extensions.
**Note:** This API cannot be called before the `ready` event of the `app` module
is emitted.
**Note:** Loading extensions into in-memory (non-persistent) sessions is not
supported and will throw an error.
#### `ses.removeExtension(extensionId)`
* `extensionId` string - ID of extension to remove
Unloads an extension.
**Note:** This API cannot be called before the `ready` event of the `app` module
is emitted.
#### `ses.getExtension(extensionId)`
* `extensionId` string - ID of extension to query
Returns `Extension` | `null` - The loaded extension with the given ID.
**Note:** This API cannot be called before the `ready` event of the `app` module
is emitted.
#### `ses.getAllExtensions()`
Returns `Extension[]` - A list of all loaded extensions.
**Note:** This API cannot be called before the `ready` event of the `app` module
is emitted.
#### `ses.getStoragePath()`
Returns `string | null` - The absolute file system path where data for this
session is persisted on disk. For in memory sessions this returns `null`.
### Instance Properties
The following properties are available on instances of `Session`:
#### `ses.availableSpellCheckerLanguages` _Readonly_
A `string[]` array which consists of all the known available spell checker languages. Providing a language
code to the `setSpellCheckerLanguages` API that isn't in this array will result in an error.
#### `ses.spellCheckerEnabled`
A `boolean` indicating whether builtin spell checker is enabled.
#### `ses.storagePath` _Readonly_
A `string | null` indicating the absolute file system path where data for this
session is persisted on disk. For in memory sessions this returns `null`.
#### `ses.cookies` _Readonly_
A [`Cookies`](cookies.md) object for this session.
#### `ses.serviceWorkers` _Readonly_
A [`ServiceWorkers`](service-workers.md) object for this session.
#### `ses.webRequest` _Readonly_

```javascript
const { app, session } = require('electron')
const path = require('path')
app.whenReady().then(() => {
const protocol = session.fromPartition('some-partition').protocol
if (!protocol.registerFileProtocol('atom', (request, callback) => {
const url = request.url.substr(7)
callback({ path: path.normalize(path.join(__dirname, url)) })
})) {
console.error('Failed to register protocol')
}
})
```
#### `ses.netLog` _Readonly_
A [`NetLog`](net-log.md) object for this session.
```javascript
const { app, session } = require('electron')
app.whenReady().then(async () => {
const netLog = session.fromPartition('some-partition').netLog

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

# webContents
> Render and control web pages.
Process: [Main](../glossary.md#main-process)
`webContents` is an [EventEmitter][event-emitter].
It is responsible for rendering and controlling a web page and is a property of
the [`BrowserWindow`](browser-window.md) object. An example of accessing the
`webContents` object:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 1500 })
win.loadURL('http://github.com')
const contents = win.webContents
console.log(contents)
```
## Navigation Events
Several events can be used to monitor navigations as they occur within a `webContents`.
### Document Navigations
When a `webContents` navigates to another page (as opposed to an [in-page navigation](web-contents.md#in-page-navigation)), the following events will be fired.
* [`did-start-navigation`](web-contents.md#event-did-start-navigation)
* [`will-frame-navigate`](web-contents.md#event-will-frame-navigate)
* [`will-navigate`](web-contents.md#event-will-navigate) (only fired when main frame navigates)
* [`will-redirect`](web-contents.md#event-will-redirect) (only fired when a redirect happens during navigation)
* [`did-redirect-navigation`](web-contents.md#event-did-redirect-navigation) (only fired when a redirect happens during navigation)
* [`did-frame-navigate`](web-contents.md#event-did-frame-navigate)
* [`did-navigate`](web-contents.md#event-did-navigate) (only fired when main frame navigates)
Subsequent events will not fire if `event.preventDefault()` is called on any of the cancellable events.
### In-page Navigation
In-page navigations don't cause the page to reload, but instead navigate to a location within the current page. These events are not cancellable. For an in-page navigations, the following events will fire in this order:
* [`did-start-navigation`](web-contents.md#event-did-start-navigation)
* [`did-navigate-in-page`](web-contents.md#event-did-navigate-in-page)
### Frame Navigation
The [`will-navigate`](web-contents.md#event-will-navigate) and [`did-navigate`](web-contents.md#event-did-navigate) events only fire when the [mainFrame](web-contents.md#contentsmainframe-readonly) navigates.
If you want to also observe navigations in `<iframe>`s, use [`will-frame-navigate`](web-contents.md#event-will-frame-navigate) and [`did-frame-navigate`](web-contents.md#event-did-frame-navigate) events.
## Methods
These methods can be accessed from the `webContents` module:
```javascript
const { webContents } = require('electron')
console.log(webContents)
```
### `webContents.getAllWebContents()`
Returns `WebContents[]` - An array of all `WebContents` instances. This will contain web contents
for all windows, webviews, opened devtools, and devtools extension background pages.
### `webContents.getFocusedWebContents()`
Returns `WebContents | null` - The web contents that is focused in this application, otherwise
returns `null`.
### `webContents.fromId(id)`
* `id` Integer
Returns `WebContents | undefined` - A WebContents instance with the given ID, or
`undefined` if there is no WebContents associated with the given ID.
### `webContents.fromFrame(frame)`
* `frame` WebFrameMain
Returns `WebContents | undefined` - A WebContents instance with the given WebFrameMain, or
`undefined` if there is no WebContents associated with the given WebFrameMain.
### `webContents.fromDevToolsTargetId(targetId)`
* `targetId` string - The Chrome DevTools Protocol [TargetID](https://chromedevtools.github.io/devtools-protocol/tot/Target/#type-TargetID) associated with the WebContents instance.
Returns `WebContents | undefined` - A WebContents instance with the given TargetID, or
`undefined` if there is no WebContents associated with the given TargetID.
When communicating with the [Chrome DevTools Protocol](https://chromedevtools.github.io/devtools-protocol/),
it can be useful to lookup a WebContents instance based on its assigned TargetID.
```js
async function lookupTargetId (browserWindow) {
const wc = browserWindow.webContents
await wc.debugger.attach('1.3')
const { targetInfo } = await wc.debugger.sendCommand('Target.getTargetInfo')
const { targetId } = targetInfo
const targetWebContents = await wc.fromDevToolsTargetId(targetId)
}
```
## Class: WebContents
> Render and control the contents of a BrowserWindow instance.
Process: [Main](../glossary.md#main-process)<br />
_This class is not exported from the `'electron'` module. It is only available as a return value of other methods in the Electron API._
### Instance Events
#### Event: 'did-finish-load'
Emitted when the navigation is done, i.e. the spinner of the tab has stopped
spinning, and the `onload` event was dispatched.
#### Event: 'did-fail-load'
Returns:
* `event` Event
* `errorCode` Integer
* `errorDescription` string
* `validatedURL` string

Emitted when page receives favicon urls.
#### Event: 'content-bounds-updated'
Returns:
* `event` Event
* `bounds` [Rectangle](structures/rectangle.md) - requested new content bounds

By default, this will move the window. To prevent that behavior, call
`event.preventDefault()`.
#### Event: 'did-create-window'
Returns:
* `window` BrowserWindow
* `details` Object
* `url` string - URL for the created window.
* `frameName` string - Name given to the created window in the
`window.open()` call.
* `options` [BrowserWindowConstructorOptions](structures/browser-window-options.md) - The options used to create the
BrowserWindow. They are merged in increasing precedence: parsed options
from the `features` string from `window.open()`, security-related
webPreferences inherited from the parent, and options given by
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
Unrecognized options are not filtered out.
* `referrer` [Referrer](structures/referrer.md) - The referrer that will be
passed to the new window. May or may not result in the `Referer` header
being sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data
that will be sent to the new window, along with the appropriate headers
that will be set. If no post data is to be sent, the value will be `null`.
Only defined when the window is being created by a form that set
`target=_blank`.
* `disposition` string - Can be `default`, `foreground-tab`,
`background-tab`, `new-window` or `other`.
Emitted _after_ successful creation of a window via `window.open` in the renderer.
Not emitted if the creation of the window is canceled from
[`webContents.setWindowOpenHandler`](web-contents.md#contentssetwindowopenhandlerhandler).
See [`window.open()`](window-open.md) for more details and how to use this in conjunction with `webContents.setWindowOpenHandler`.
#### Event: 'will-navigate'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - This event does not fire for same document navigations using window.history api and reference fragment navigations.
This property is always set to `false` for this event.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
* `url` string _Deprecated_
* `isInPlace` boolean _Deprecated_
* `isMainFrame` boolean _Deprecated_
* `frameProcessId` Integer _Deprecated_
* `frameRoutingId` Integer _Deprecated_
Emitted when a user or the page wants to start navigation on the main frame. It can happen when
the `window.location` object is changed or a user clicks a link in the page.
This event will not emit when the navigation is started programmatically with
APIs like `webContents.loadURL` and `webContents.back`.
It is also not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` will prevent the navigation.
#### Event: 'will-frame-navigate'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - This event does not fire for same document navigations using window.history api and reference fragment navigations.
This property is always set to `false` for this event.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
Emitted when a user or the page wants to start navigation in any frame. It can happen when
the `window.location` object is changed or a user clicks a link in the page.
Unlike `will-navigate`, `will-frame-navigate` is fired when the main frame or any of its subframes attempts to navigate. When the navigation event comes from the main frame, `isMainFrame` will be `true`.
This event will not emit when the navigation is started programmatically with
APIs like `webContents.loadURL` and `webContents.back`.
It is also not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` will prevent the navigation.
#### Event: 'did-start-navigation'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - Whether the navigation happened without changing
document. Examples of same document navigations are reference fragment
navigations, pushState/replaceState, and same page history navigation.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a

emitted.
* `url` string _Deprecated_
* `isInPlace` boolean _Deprecated_
* `isMainFrame` boolean _Deprecated_
* `frameProcessId` Integer _Deprecated_
* `frameRoutingId` Integer _Deprecated_

#### Event: 'will-redirect'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - Whether the navigation happened without changing
document. Examples of same document navigations are reference fragment
navigations, pushState/replaceState, and same page history navigation.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
* `url` string _Deprecated_
* `isInPlace` boolean _Deprecated_
* `isMainFrame` boolean _Deprecated_
* `frameProcessId` Integer _Deprecated_
* `frameRoutingId` Integer _Deprecated_
Emitted when a server side redirect occurs during navigation. For example a 302
redirect.
This event will be emitted after `did-start-navigation` and always before the
`did-redirect-navigation` event for the same navigation.
Calling `event.preventDefault()` will prevent the navigation (not just the
redirect).
#### Event: 'did-redirect-navigation'
Returns:
* `details` Event<>
* `url` string - The URL the frame is navigating to.
* `isSameDocument` boolean - Whether the navigation happened without changing
document. Examples of same document navigations are reference fragment
navigations, pushState/replaceState, and same page history navigation.
* `isMainFrame` boolean - True if the navigation is taking place in a main frame.
* `frame` WebFrameMain - The frame to be navigated.
* `initiator` WebFrameMain (optional) - The frame which initiated the
navigation, which can be a parent frame (e.g. via `window.open` with a
frame's name), or null if the navigation was not initiated by a frame. This
can also be null if the initiating frame was deleted before the event was
emitted.
* `url` string _Deprecated_
* `isInPlace` boolean _Deprecated_
* `isMainFrame` boolean _Deprecated_
* `frameProcessId` Integer _Deprecated_
* `frameRoutingId` Integer _Deprecated_
Emitted after a server side redirect occurs during navigation. For example a 302
redirect.
This event cannot be prevented, if you want to prevent redirects you should
checkout out the `will-redirect` event above.
#### Event: 'did-navigate'
Returns:
* `event` Event
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations
Emitted when a main frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
#### Event: 'did-frame-navigate'
Returns:
* `event` Event
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations,
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when any frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
#### Event: 'did-navigate-in-page'
Returns:
* `event` Event
* `url` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when an in-page navigation happened in any frame.
When in-page navigation happens, the page URL changes but does not cause
navigation outside of the page. Examples of this occurring are when anchor links
are clicked or when the DOM `hashchange` event is triggered.
#### Event: 'will-prevent-unload'
Returns:
* `event` Event
Emitted when a `beforeunload` event handler is attempting to cancel a page unload.
Calling `event.preventDefault()` will ignore the `beforeunload` event handler
and allow the page to be unloaded.
```javascript
const { BrowserWindow, dialog } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('will-prevent-unload', (event) => {
const choice = dialog.showMessageBoxSync(win, {
type: 'question',
buttons: ['Leave', 'Stay'],
title: 'Do you want to leave this site?',
message: 'Changes you made may not be saved.',
defaultId: 0,
cancelId: 1
})
const leave = (choice === 0)
if (leave) {
event.preventDefault()
}
})
```
**Note:** This will be emitted for `BrowserViews` but will _not_ be respected - this is because we have chosen not to tie the `BrowserView` lifecycle to its owning BrowserWindow should one exist per the [specification](https://developer.mozilla.org/en-US/docs/Web/API/Window/beforeunload_event).
#### Event: 'crashed' _Deprecated_
Returns:
* `event` Event
* `killed` boolean
Emitted when the renderer process 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
* `details` Object
* `reason` string - The reason the render process is gone. Possible values:
* `clean-exit` - Process exited with an exit code of zero
* `abnormal-exit` - Process exited with a non-zero exit code
* `killed` - Process was sent a SIGTERM or otherwise killed externally
* `crashed` - Process crashed
* `oom` - Process ran out of memory
* `launch-failed` - Process never successfully launched
* `integrity-failure` - Windows code integrity checks failed
* `exitCode` Integer - The exit code of the process, unless `reason` is
`launch-failed`, in which case `exitCode` will be a platform-specific
launch failure error code.
Emitted when the renderer process unexpectedly disappears. This is normally
because it was crashed or killed.
#### Event: 'unresponsive'
Emitted when the web page becomes unresponsive.
#### Event: 'responsive'
Emitted when the unresponsive web page becomes responsive again.
#### Event: 'plugin-crashed'
Returns:
* `event` Event
* `name` string
* `version` string
Emitted when a plugin process has crashed.
#### Event: 'destroyed'
Emitted when `webContents` is destroyed.
#### Event: 'input-event'
Returns:
* `event` Event
* `inputEvent` [InputEvent](structures/input-event.md)
Emitted when an input event is sent to the WebContents. See
[InputEvent](structures/input-event.md) for details.
#### Event: 'before-input-event'
Returns:
* `event` Event
* `input` Object - Input properties.
* `type` string - Either `keyUp` or `keyDown`.
* `key` string - Equivalent to [KeyboardEvent.key][keyboardevent].
* `code` string - Equivalent to [KeyboardEvent.code][keyboardevent].

Emitted before dispatching the `keydown` and `keyup` events in the page.
Calling `event.preventDefault` will prevent the page `keydown`/`keyup` events
and the menu shortcuts.
To only prevent the menu shortcuts, use
[`setIgnoreMenuShortcuts`](#contentssetignoremenushortcutsignore):
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('before-input-event', (event, input) => {
// For example, only enable application menu keyboard shortcuts when
// Ctrl/Cmd are down.
win.webContents.setIgnoreMenuShortcuts(!input.control && !input.meta)
})
```
#### Event: 'enter-html-full-screen'
Emitted when the window enters a full-screen state triggered by HTML API.

Note that on macOS, having focus means the `WebContents` is the first responder
of window, so switching focus between windows would not trigger the `focus` and
`blur` events of `WebContents`, as the first responder of each window is not

the `deviceId` of the device to be selected. Passing an empty string to
`callback` will cancel the request.
If an event listener is not added for this event, or if `event.preventDefault`
is not called when handling this event, the first available device will be
automatically selected.
Due to the nature of bluetooth, scanning for devices when
`navigator.bluetooth.requestDevice` is called may take time and will cause
`select-bluetooth-device` to fire multiple times until `callback` is called
with either a device id or an empty string to cancel the request.

let win = null
app.whenReady().then(() => {
win = new BrowserWindow({ width: 800, height: 600 })
win.webContents.on('select-bluetooth-device', (event, deviceList, callback) => {
event.preventDefault()
const result = deviceList.find((device) => {
return device.deviceName === 'test'
})
if (!result) {
// The device wasn't found so we need to either wait longer (eg until the
// device is turned on) or cancel the request by calling the callback
// with an empty string.
callback('')
} else {
callback(result.deviceId)
}
})
})
```

* `postData` ([UploadRawData](structures/upload-raw-data.md) | [UploadFile](structures/upload-file.md))[] (optional)
* `baseURLForDataURL` string (optional) - Base url (with trailing path separator) for files to be loaded by the data url. This is needed only if the specified `url` is a data url and needs to load other files.
Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see
[`did-fail-load`](web-contents.md#event-did-fail-load)). A noop rejection handler is already attached, which avoids unhandled rejection errors.
Loads the `url` in the window. The `url` must contain the protocol prefix,
e.g. the `http://` or `file://`. If the load should bypass http cache then
use the `pragma` header to achieve it.
```javascript
const win = new BrowserWindow()
const options = { extraHeaders: 'pragma: no-cache\n' }
win.webContents.loadURL('https://github.com', options)
```
#### `contents.loadFile(filePath[, options])`

Returns `Promise<void>` - the promise will resolve when the page has finished loading
(see [`did-finish-load`](web-contents.md#event-did-finish-load)), and rejects
if the page fails to load (see [`did-fail-load`](web-contents.md#event-did-fail-load)).
Loads the given file in the window, `filePath` should be a path to
an HTML file relative to the root of your application. For instance
an app structure like this:
```sh
| root
| - package.json
| - src
| - main.js
| - index.html
```
Would require code like this
```js
const win = new BrowserWindow()
win.loadFile('src/index.html')
```
#### `contents.downloadURL(url)`
* `url` string
Initiates a download of the resource at `url` without navigating. The
`will-download` event of `session` will be triggered.
#### `contents.getURL()`
Returns `string` - The URL of the current web page.
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow({ width: 800, height: 600 })
win.loadURL('http://github.com').then(() => {
const currentURL = win.webContents.getURL()
console.log(currentURL)
})
```
#### `contents.getTitle()`
Returns `string` - The title of the current web page.
#### `contents.isDestroyed()`
Returns `boolean` - Whether the web page is destroyed.
#### `contents.close([opts])`
* `opts` Object (optional)
* `waitForBeforeUnload` boolean - if true, fire the `beforeunload` event
before closing the page. If the page prevents the unload, the WebContents
will not be closed. The [`will-prevent-unload`](#event-will-prevent-unload)
will be fired if the page requests prevention of unload.
Closes the page, as if the web content had called `window.close()`.
If the page is successfully closed (i.e. the unload is not prevented by the
page, or `waitForBeforeUnload` is false or unspecified), the WebContents will
be destroyed and no longer usable. The [`destroyed`](#event-destroyed) event
will be emitted.
#### `contents.focus()`
Focuses the web page.
#### `contents.isFocused()`
Returns `boolean` - Whether the web page is focused.
#### `contents.isLoading()`
Returns `boolean` - Whether web page is still loading resources.

#### `contents.isCrashed()`
Returns `boolean` - Whether the renderer process has crashed.
#### `contents.forcefullyCrashRenderer()`
Forcefully terminates the renderer process that is currently hosting this
`webContents`. This will cause the `render-process-gone` event to be emitted
with the `reason=killed || reason=crashed`. Please note that some webContents share renderer
processes and therefore calling this method may also crash the host process
for other webContents as well.
Calling `reload()` immediately after calling this
method will force the reload to occur in a new process. This should be used
when this process is unstable or unusable, for instance in order to recover
from the `unresponsive` event.
```js
const win = new BrowserWindow()
win.webContents.on('unresponsive', async () => {
const { response } = await dialog.showMessageBox({
message: 'App X has become unresponsive',
title: 'Do you want to try forcefully reloading the app?',
buttons: ['OK', 'Cancel'],
cancelId: 1
})
if (response === 0) {
win.webContents.forcefullyCrashRenderer()
win.webContents.reload()
}
})
```

Returns `Promise<string>` - A promise that resolves with a key for the inserted CSS that can later be used to remove the CSS via `contents.removeInsertedCSS(key)`.
Injects CSS into the current web page and returns a unique key for the inserted
stylesheet.
```js
const win = new BrowserWindow()
win.webContents.on('did-finish-load', () => {
win.webContents.insertCSS('html, body { background-color: #f00; }')
})
```
#### `contents.removeInsertedCSS(key)`
* `key` string
Returns `Promise<void>` - Resolves if the removal was successful.
Removes the inserted CSS from the current web page. The stylesheet is identified
by its key, which is returned from `contents.insertCSS(css)`.
```js
const win = new BrowserWindow()
win.webContents.on('did-finish-load', async () => {
const key = await win.webContents.insertCSS('html, body { background-color: #f00; }')
win.webContents.removeInsertedCSS(key)
})
```
#### `contents.executeJavaScript(code[, userGesture])`
* `code` string
* `userGesture` boolean (optional) - Default is `false`.
Returns `Promise<any>` - A promise that resolves with the result of the executed code
or is rejected if the result of the code is a rejected promise.
Evaluates `code` in page.
In the browser window some HTML APIs like `requestFullScreen` can only be
invoked by a gesture from the user. Setting `userGesture` to `true` will remove
this limitation.
Code execution will be suspended until web page stop loading.
```js
const win = new BrowserWindow()
win.webContents.executeJavaScript('fetch("https://jsonplaceholder.typicode.com/users/1").then(resp => resp.json())', true)
.then((result) => {
console.log(result) // Will be the JSON object from the fetch call
})
```
#### `contents.executeJavaScriptInIsolatedWorld(worldId, scripts[, userGesture])`
* `worldId` Integer - The ID of the world to run the javascript in, `0` is the default world, `999` is the world used by Electron's `contextIsolation` feature. You can provide any integer here.
* `scripts` [WebSource[]](structures/web-source.md)
* `userGesture` boolean (optional) - Default is `false`.
Returns `Promise<any>` - A promise that resolves with the result of the executed code
or is rejected if the result of the code is a rejected promise.
Works like `executeJavaScript` but evaluates `scripts` in an isolated context.
#### `contents.setIgnoreMenuShortcuts(ignore)`
* `ignore` boolean
Ignore application menu shortcuts while this web contents is focused.
#### `contents.setWindowOpenHandler(handler)`
* `handler` Function<{action: 'deny'} | {action: 'allow', outlivesOpener?: boolean, overrideBrowserWindowOptions?: BrowserWindowConstructorOptions}>
* `details` Object
* `url` string - The _resolved_ version of the URL passed to `window.open()`. e.g. opening a window with `window.open('foo')` will yield something like `https://the-origin/the/current/path/foo`.
* `frameName` string - Name of the window provided in `window.open()`
* `features` string - Comma separated list of window features provided to `window.open()`.
* `disposition` string - Can be `default`, `foreground-tab`, `background-tab`,
`new-window` or `other`.
* `referrer` [Referrer](structures/referrer.md) - The referrer that will be
passed to the new window. May or may not result in the `Referer` header being
sent, depending on the referrer policy.
* `postBody` [PostBody](structures/post-body.md) (optional) - The post data that
will be sent to the new window, along with the appropriate headers that will
be set. If no post data is to be sent, the value will be `null`. Only defined
when the window is being created by a form that set `target=_blank`.
Returns `{action: 'deny'} | {action: 'allow', outlivesOpener?: boolean, overrideBrowserWindowOptions?: BrowserWindowConstructorOptions}` - `deny` cancels the creation of the new
window. `allow` will allow the new window to be created. Specifying `overrideBrowserWindowOptions` allows customization of the created window.
By default, child windows are closed when their opener is closed. This can be
changed by specifying `outlivesOpener: true`, in which case the opened window
will not be closed when its opener is closed.
Returning an unrecognized value such as a null, undefined, or an object
without a recognized 'action' value will result in a console error and have
the same effect as returning `{action: 'deny'}`.
Called before creating a window a new window is requested by the renderer, e.g.
by `window.open()`, a link with `target="_blank"`, shift+clicking on a link, or
submitting a form with `<form target="_blank">`. See
[`window.open()`](window-open.md) for more details and how to use this in
conjunction with `did-create-window`.
#### `contents.setAudioMuted(muted)`
* `muted` boolean
Mute the audio on the current web page.
#### `contents.isAudioMuted()`

#### `contents.isCurrentlyAudible()`
Returns `boolean` - Whether audio is currently playing.
#### `contents.setZoomFactor(factor)`
* `factor` Double - Zoom factor; default is 1.0.
Changes the zoom factor to the specified factor. Zoom factor is
zoom percent divided by 100, so 300% = 3.0.
The factor must be greater than 0.0.
#### `contents.getZoomFactor()`
Returns `number` - the current zoom factor.
#### `contents.setZoomLevel(level)`
* `level` number - Zoom level.
Changes the zoom level to the specified level. The original size is 0 and each
increment above or below represents zooming 20% larger or smaller to default
limits of 300% and 50% of original size, respectively. The formula for this is
`scale := 1.2 ^ level`.
> **NOTE**: The zoom policy at the Chromium level is same-origin, meaning that the
> zoom level for a specific domain propagates across all instances of windows with

#### `contents.addWorkSpace(path)`
* `path` string
Adds the specified path to DevTools workspace. Must be used after DevTools
creation:
```javascript
const { BrowserWindow } = require('electron')
const win = new BrowserWindow()
win.webContents.on('devtools-opened', () => {
win.webContents.addWorkSpace(__dirname)
})
```
#### `contents.removeWorkSpace(path)`
* `path` string
Removes the specified path from DevTools workspace.
#### `contents.setDevToolsWebContents(devToolsWebContents)`
* `devToolsWebContents` WebContents
Uses the `devToolsWebContents` as the target `WebContents` to show devtools.
The `devToolsWebContents` must not have done any navigation, and it should not
be used for other purposes after the call.
By default Electron manages the devtools by creating an internal `WebContents`
with native view, which developers have very limited control of. With the
`setDevToolsWebContents` method, developers can use any `WebContents` to show
the devtools in it, including `BrowserWindow`, `BrowserView` and `<webview>`
tag.
Note that closing the devtools does not destroy the `devToolsWebContents`, it
is caller's responsibility to destroy `devToolsWebContents`.
An example of showing devtools in a `<webview>` tag:
```html
<html>
<head>
<style type="text/css">
* { margin: 0; }
#browser { height: 70%; }
#devtools { height: 30%; }
</style>
</head>
<body>
<webview id="browser" src="https://github.com"></webview>
<webview id="devtools" src="about:blank"></webview>
<script>
const { ipcRenderer } = require('electron')
const emittedOnce = (element, eventName) => new Promise(resolve => {
element.addEventListener(eventName, event => resolve(event), { once: true })
})
const browserView = document.getElementById('browser')
const devtoolsView = document.getElementById('devtools')
const browserReady = emittedOnce(browserView, 'dom-ready')
const devtoolsReady = emittedOnce(devtoolsView, 'dom-ready')
Promise.all([browserReady, devtoolsReady]).then(() => {
const targetId = browserView.getWebContentsId()
const devtoolsId = devtoolsView.getWebContentsId()
ipcRenderer.send('open-devtools', targetId, devtoolsId)
})
</script>
</body>
</html>
```
```js
// Main process
const { ipcMain, webContents } = require('electron')
ipcMain.on('open-devtools', (event, targetContentsId, devtoolsContentsId) => {
const target = webContents.fromId(targetContentsId)
const devtools = webContents.fromId(devtoolsContentsId)
target.setDevToolsWebContents(devtools)
target.openDevTools()
})
```
An example of showing devtools in a `BrowserWindow`:
```js title='main.js'
const { app, BrowserWindow } = require('electron')
let win = null
let devtools = null
app.whenReady().then(() => {
win = new BrowserWindow()
devtools = new BrowserWindow()
win.loadURL('https://github.com')
win.webContents.setDevToolsWebContents(devtools.webContents)
win.webContents.openDevTools({ mode: 'detach' })
})
```
#### `contents.openDevTools([options])`
* `options` Object (optional)
* `mode` string - Opens the devtools with specified dock state, can be
`left`, `right`, `bottom`, `undocked`, `detach`. Defaults to last used dock state.
In `undocked` mode it's possible to dock back. In `detach` mode it's not.
* `activate` boolean (optional) - Whether to bring the opened devtools window
to the foreground. The default is `true`.
Opens the devtools.
When `contents` is a `<webview>` tag, the `mode` would be `detach` by default,
explicitly passing an empty `mode` can force using last used dock state.
On Windows, if Windows Control Overlay is enabled, Devtools will be opened with `mode: 'detach'`.
#### `contents.closeDevTools()`
Closes the devtools.
#### `contents.isDevToolsOpened()`
Returns `boolean` - Whether the devtools is opened.
#### `contents.isDevToolsFocused()`
Returns `boolean` - Whether the devtools view is focused .
#### `contents.toggleDevTools()`
Toggles the developer tools.
#### `contents.inspectElement(x, y)`
* `x` Integer
* `y` Integer
Starts inspecting element at position (`x`, `y`).
#### `contents.inspectSharedWorker()`
Opens the developer tools for the shared worker context.
#### `contents.inspectSharedWorkerById(workerId)`
* `workerId` string
Inspects the shared worker based on its ID.
#### `contents.getAllSharedWorkers()`
Returns [`SharedWorkerInfo[]`](structures/shared-worker-info.md) - Information about all Shared Workers.
#### `contents.inspectServiceWorker()`
Opens the developer tools for the service worker context.
#### `contents.send(channel, ...args)`
* `channel` string
* `...args` any[]
Send an asynchronous message to the renderer process via `channel`, along with
arguments. Arguments will be serialized with the [Structured Clone
Algorithm][SCA], just like [`postMessage`][], so prototype chains will not be
included. Sending Functions, Promises, Symbols, WeakMaps, or WeakSets will
throw an exception.
:::warning
Sending non-standard JavaScript types such as DOM objects or
special Electron objects will throw an exception.
:::
For additional reading, refer to [Electron's IPC guide](../tutorial/ipc.md).
#### `contents.sendToFrame(frameId, channel, ...args)`
* `frameId` Integer | \[number, number] - the ID of the frame to send to, or a
pair of `[processId, frameId]` if the frame is in a different process to the
main frame.
* `channel` string
* `...args` any[]
Send an asynchronous message to a specific frame in a renderer process via
`channel`, along with arguments. Arguments will be serialized with the
[Structured Clone Algorithm][SCA], just like [`postMessage`][], so prototype
chains will not be included. Sending Functions, Promises, Symbols, WeakMaps, or
WeakSets will throw an exception.
> **NOTE:** Sending non-standard JavaScript types such as DOM objects or
> special Electron objects will throw an exception.
The renderer process can handle the message by listening to `channel` with the
[`ipcRenderer`](ipc-renderer.md) module.
If you want to get the `frameId` of a given renderer context you should use
the `webFrame.routingId` value. E.g.
```js
// In a renderer process
console.log('My frameId is:', require('electron').webFrame.routingId)
```
You can also read `frameId` from all incoming IPC messages in the main process.
```js
// In the main process
ipcMain.on('ping', (event) => {
console.info('Message came from frameId:', event.frameId)
})
```
#### `contents.postMessage(channel, message, [transfer])`
* `channel` string
* `message` any
* `transfer` MessagePortMain[] (optional)
Send a message to the renderer process, optionally transferring ownership of
zero or more [`MessagePortMain`][] objects.
The transferred `MessagePortMain` objects will be available in the renderer
process by accessing the `ports` property of the emitted event. When they
arrive in the renderer, they will be native DOM `MessagePort` objects.
For example:
```js
// Main process
const win = new BrowserWindow()
const { port1, port2 } = new MessageChannelMain()
win.webContents.postMessage('port', { message: 'hello' }, [port1])
// Renderer process
ipcRenderer.on('port', (e, msg) => {
const [port] = e.ports
// ...
})
```

view mode) (default: `1`).
Enable device emulation with the given parameters.
#### `contents.disableDeviceEmulation()`
Disable device emulation enabled by `webContents.enableDeviceEmulation`.
#### `contents.sendInputEvent(inputEvent)`
* `inputEvent` [MouseInputEvent](structures/mouse-input-event.md) | [MouseWheelInputEvent](structures/mouse-wheel-input-event.md) | [KeyboardInputEvent](structures/keyboard-input-event.md)
Sends an input `event` to the page.
**Note:** The [`BrowserWindow`](browser-window.md) containing the contents needs to be focused for
`sendInputEvent()` to work.
#### `contents.beginFrameSubscription([onlyDirty ,]callback)`
* `onlyDirty` boolean (optional) - Defaults to `false`.
* `callback` Function
* `image` [NativeImage](native-image.md)
* `dirtyRect` [Rectangle](structures/rectangle.md)
Begin subscribing for presentation events and captured frames, the `callback`
will be called with `callback(image, dirtyRect)` when there is a presentation
event.
The `image` is an instance of [NativeImage](native-image.md) that stores the
captured frame.
The `dirtyRect` is an object with `x, y, width, height` properties that
describes which part of the page was repainted. If `onlyDirty` is set to
`true`, `image` will only contain the repainted area. `onlyDirty` defaults to
`false`.

behavior. When this policy is used, WebRTC has the right to enumerate all
interfaces and bind them to discover public interfaces.
* `default_public_interface_only` - Exposes user's public IP, but does not
expose user's local IP. When this policy is used, WebRTC should only use the
default route used by http. This doesn't expose any local addresses.
* `default_public_and_private_interfaces` - Exposes user's public and local
IPs. When this policy is used, WebRTC should only use the default route used
by http. This also exposes the associated default private address. Default
route is the route chosen by the OS on a multi-homed endpoint.
* `disable_non_proxied_udp` - Does not expose public or local IPs. When this
policy is used, WebRTC should only use TCP to contact peers or servers unless
the proxy server supports UDP.
Setting the WebRTC IP handling policy allows you to control which IPs are
exposed via WebRTC. See [BrowserLeaks](https://browserleaks.com/webrtc) for
more details.
#### `contents.getMediaSourceId(requestWebContents)`
* `requestWebContents` WebContents - Web contents that the id will be registered to.

Returns `Integer` - The operating system `pid` of the associated renderer
process.
#### `contents.getProcessId()`
Returns `Integer` - The Chromium internal `pid` of the associated renderer. Can
be compared to the `frameProcessId` passed by frame specific navigation events
(e.g. `did-frame-navigate`)
#### `contents.takeHeapSnapshot(filePath)`
* `filePath` string - Path to the output file.
Returns `Promise<void>` - Indicates whether the snapshot has been created successfully.
Takes a V8 heap snapshot and saves it to `filePath`.
#### `contents.getBackgroundThrottling()`
Returns `boolean` - whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.setBackgroundThrottling(allowed)`
* `allowed` boolean
Controls whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.getType()`
Returns `string` - the type of the webContent. Can be `backgroundPage`, `window`, `browserView`, `remote`, `webview` or `offscreen`.
#### `contents.setImageAnimationPolicy(policy)`
* `policy` string - Can be `animate`, `animateOnce` or `noAnimation`.
Sets the image animation policy for this webContents. The policy only affects
_new_ images, existing images that are currently being animated are unaffected.
This is a known limitation in Chromium, you can force image animation to be
recalculated with `img.src = img.src` which will result in no network traffic
but will update the animation policy.
This corresponds to the [animationPolicy][] accessibility feature in Chromium.
[animationPolicy]: https://developer.chrome.com/docs/extensions/reference/accessibilityFeatures/#property-animationPolicy
### Instance Properties
#### `contents.ipc` _Readonly_
An [`IpcMain`](ipc-main.md) scoped to just IPC messages sent from this
WebContents.
IPC messages sent with `ipcRenderer.send`, `ipcRenderer.sendSync` or
`ipcRenderer.postMessage` will be delivered in the following order:
1. `contents.on('ipc-message')`
2. `contents.mainFrame.on(channel)`
3. `contents.ipc.on(channel)`
4. `ipcMain.on(channel)`
Handlers registered with `invoke` will be checked in the following order. The
first one that is defined will be called, the rest will be ignored.
1. `contents.mainFrame.handle(channel)`
2. `contents.handle(channel)`
3. `ipcMain.handle(channel)`
A handler or event listener registered on the WebContents will receive IPC
messages sent from any frame, including child frames. In most cases, only the
main frame can send IPC messages. However, if the `nodeIntegrationInSubFrames`
option is enabled, it is possible for child frames to send IPC messages also.
In that case, handlers should check the `senderFrame` property of the IPC event
to ensure that the message is coming from the expected frame. Alternatively,
register handlers on the appropriate frame directly using the
[`WebFrameMain.ipc`](web-frame-main.md#frameipc-readonly) interface.
#### `contents.audioMuted`
A `boolean` property that determines whether this page is muted.
#### `contents.userAgent`
A `string` property that determines the user agent for this web page.
#### `contents.zoomLevel`
A `number` property that determines the zoom level for this web contents.
The original size is 0 and each increment above or below represents zooming 20% larger or smaller to default limits of 300% and 50% of original size, respectively. The formula for this is `scale := 1.2 ^ level`.
#### `contents.zoomFactor`
A `number` property that determines the zoom factor for this web contents.
The zoom factor is the zoom percent divided by 100, so 300% = 3.0.
#### `contents.frameRate`
An `Integer` property that sets the frame rate of the web contents to the specified number.
Only values between 1 and 240 are accepted.
Only applicable if _offscreen rendering_ is enabled.
#### `contents.id` _Readonly_
A `Integer` representing the unique ID of this WebContents. Each ID is unique among all `WebContents` instances of the entire Electron application.
#### `contents.session` _Readonly_
A [`Session`](session.md) used by this webContents.
#### `contents.hostWebContents` _Readonly_
A [`WebContents`](web-contents.md) instance that might own this `WebContents`.
#### `contents.devToolsWebContents` _Readonly_
A `WebContents | null` property that represents the of DevTools `WebContents` associated with a given `WebContents`.
**Note:** Users should never store this object because it may become `null`
when the DevTools has been closed.
#### `contents.debugger` _Readonly_
A [`Debugger`](debugger.md) instance for this webContents.
#### `contents.backgroundThrottling`
A `boolean` property that determines whether or not this WebContents will throttle animations and timers
when the page becomes backgrounded. This also affects the Page Visibility API.
#### `contents.mainFrame` _Readonly_
A [`WebFrameMain`](web-frame-main.md) property that represents the top frame of the page's frame hierarchy.
#### `contents.opener` _Readonly_
A [`WebFrameMain`](web-frame-main.md) property that represents the frame that opened this WebContents, either
with open(), or by navigating a link with a target attribute.

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

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

Changes the zoom level to the specified level. The original size is 0 and each
increment above or below represents zooming 20% larger or smaller to default
limits of 300% and 50% of original size, respectively. The formula for this is
`scale := 1.2 ^ level`.
> **NOTE**: The zoom policy at the Chromium level is same-origin, meaning that the
> zoom level for a specific domain propagates across all instances of windows with
> the same domain. Differentiating the window URLs will make zoom work per-window.
### `<webview>.getZoomFactor()`
Returns `number` - the current zoom factor.
### `<webview>.getZoomLevel()`
Returns `number` - the current zoom level.
### `<webview>.setVisualZoomLevelLimits(minimumLevel, maximumLevel)`
* `minimumLevel` number
* `maximumLevel` number
Returns `Promise<void>`
Sets the maximum and minimum pinch-to-zoom level.
### `<webview>.showDefinitionForSelection()` _macOS_
Shows pop-up dictionary that searches the selected word on the page.
### `<webview>.getWebContentsId()`
Returns `number` - The WebContents ID of this `webview`.
## DOM Events
The following DOM events are available to the `webview` tag:
### Event: 'load-commit'
Returns:
* `url` string
* `isMainFrame` boolean
Fired when a load has committed. This includes navigation within the current
document as well as subframe document-level loads, but does not include
asynchronous resource loads.
### Event: 'did-finish-load'
Fired when the navigation is done, i.e. the spinner of the tab will stop
spinning, and the `onload` event is dispatched.
### Event: 'did-fail-load'
Returns:
* `errorCode` Integer
* `errorDescription` string
* `validatedURL` string
* `isMainFrame` boolean
This event is like `did-finish-load`, but fired when the load failed or was
cancelled, e.g. `window.stop()` is invoked.
### Event: 'did-frame-finish-load'
Returns:
* `isMainFrame` boolean
Fired when a frame has done navigation.
### Event: 'did-start-loading'
Corresponds to the points in time when the spinner of the tab starts spinning.
### Event: 'did-stop-loading'
Corresponds to the points in time when the spinner of the tab stops spinning.
### Event: 'did-attach'
Fired when attached to the embedder web contents.
### Event: 'dom-ready'
Fired when document in the given frame is loaded.
### Event: 'page-title-updated'
Returns:
* `title` string
* `explicitSet` boolean
Fired when page title is set during navigation. `explicitSet` is false when
title is synthesized from file url.
### Event: 'page-favicon-updated'
Returns:

* `message` string - The actual console message
* `line` Integer - The line number of the source that triggered this console message
* `sourceId` string
Fired when the guest window logs a console message.
The following example code forwards all log messages to the embedder's console
without regard for log level or other properties.
```javascript @ts-expect-error=[3]
const webview = document.querySelector('webview')
webview.addEventListener('console-message', (e) => {
console.log('Guest page logged a message:', e.message)
})
```
### Event: 'found-in-page'
Returns:
* `result` Object
* `requestId` Integer
* `activeMatchOrdinal` Integer - Position of the active match.
* `matches` Integer - Number of Matches.
* `selectionArea` Rectangle - Coordinates of first match region.
* `finalUpdate` boolean
Fired when a result is available for
[`webview.findInPage`](#webviewfindinpagetext-options) request.
```javascript @ts-expect-error=[3,6]
const webview = document.querySelector('webview')
webview.addEventListener('found-in-page', (e) => {
webview.stopFindInPage('keepSelection')
})
const requestId = webview.findInPage('test')
console.log(requestId)
```
### Event: 'will-navigate'
Returns:
* `url` string
Emitted when a user or the page wants to start navigation. It can happen when
the `window.location` object is changed or a user clicks a link in the page.
This event will not emit when the navigation is started programmatically with
APIs like `<webview>.loadURL` and `<webview>.back`.
It is also not emitted during in-page navigation, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` does **NOT** have any effect.
### Event: 'will-frame-navigate'
Returns:
* `url` string
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when a user or the page wants to start navigation anywhere in the `<webview>`
or any frames embedded within. It can happen when the `window.location` object is
changed or a user clicks a link in the page.
This event will not emit when the navigation is started programmatically with
APIs like `<webview>.loadURL` and `<webview>.back`.
It is also not emitted during in-page navigation, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
Calling `event.preventDefault()` does **NOT** have any effect.
### Event: 'did-start-navigation'
Returns:
* `url` string
* `isInPlace` boolean
* `isMainFrame` boolean

Returns:
* `url` string
* `isInPlace` boolean
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted after a server side redirect occurs during navigation. For example a 302
redirect.
### Event: 'did-navigate'
Returns:
* `url` string
Emitted when a navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
### Event: 'did-frame-navigate'
Returns:
* `url` string
* `httpResponseCode` Integer - -1 for non HTTP navigations
* `httpStatusText` string - empty for non HTTP navigations,
* `isMainFrame` boolean
* `frameProcessId` Integer
* `frameRoutingId` Integer
Emitted when any frame navigation is done.
This event is not emitted for in-page navigations, such as clicking anchor links
or updating the `window.location.hash`. Use `did-navigate-in-page` event for
this purpose.
### Event: 'did-navigate-in-page'
Returns:
* `isMainFrame` boolean
* `url` string
Emitted when an in-page navigation happened.
When in-page navigation happens, the page URL changes but does not cause
navigation outside of the page. Examples of this occurring are when anchor links
are clicked or when the DOM `hashchange` event is triggered.
### Event: 'close'
Fired when the guest page attempts to close itself.
The following example code navigates the `webview` to `about:blank` when the
guest attempts to close itself.
```javascript @ts-expect-error=[3]
const webview = document.querySelector('webview')
webview.addEventListener('close', () => {
webview.src = 'about:blank'
})
```
### Event: 'ipc-message'
Returns:
* `frameId` \[number, number] - pair of `[processId, frameId]`.
* `channel` string
* `args` any[]
Fired when the guest page has sent an asynchronous message to embedder page.
With `sendToHost` method and `ipc-message` event you can communicate
between guest page and embedder page:
```javascript @ts-expect-error=[4,7]
// In embedder page.
const webview = document.querySelector('webview')
webview.addEventListener('ipc-message', (event) => {
console.log(event.channel)
// Prints "pong"
})
webview.send('ping')
```
```javascript
// In guest page.
const { ipcRenderer } = require('electron')

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

Improve Type Union Typings in the Docs
|
[The phrasings that `electron/docs-parser` recognizes for string union types](https://github.com/electron/docs-parser/blob/c56164b4cebcf010306e0458729bf179bf69e650/src/markdown-helpers.ts#L459) is fairly narrow, and it looks like there's a handful of places in the docs where the phrasing is not being picked up as string union types.
Fix these and add smoke tests with `// @ts-expect-error` to ensure type unions are being used. See #38336 for an example.
Alternatively, extend the phrasings that `electron/docs-parser` recognizes, and add the smoke tests.
A (possibly non-exhaustive) list of ones which aren't being picked up. There's [an upstream issue](https://github.com/electron/docs-parser/issues/88) preventing certain values from being picked up.

[Bug]: Chrome Extension V3 service_worker - Supported APIs do not function
|
### 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
13.6.9, 18.2.0, 20.0.0-nightly.20220505
### What operating system are you using?
macOS
### Operating System Version
macOS Monterey 12.3.1
### What arch are you using?
x64
### Last Known Working Electron version
N/A
### Expected Behavior
For successful messages to be sent to and from the Service Worker in the extension.
The test case provided uses Electron's supported Chrome APIs as defined here: https://www.electronjs.org/docs/latest/api/extensions#loading-extensions
- A content page is supplied by this extension which simply calls "chrome.runtime.sendMessage" to send a message.
- A service worker is supplied by this extension which calls
- "chrome.runtime.onInstalled" to print a logging statement
- "chrome.runtime.onMessage.addListener" to listen for messages, and to send a response.
Expected to see the log message show up on any web page:
`I'm a content script, and I'm going to try to send a message to anyone that is listening.`
`Hello sender, I received your message.`
With the ELECTRON_ENABLE_LOGGING=1 env set, expected to see:
`[xxx:INFO:CONSOLE(1)] "Hello, I'm a service worker", source: chrome-extension:///<some_chrome_extension_id>/background.js`
`[xxx:INFO:CONSOLE(1)] "Hello, I was just installed.", source: chrome-extension:///<some_chrome_extension_id>/background.js`
`[xxx:INFO:CONSOLE(1)] "Hello, I'm a service worker and I just received a message.", source: chrome-extension:///<some_chrome_extension_id>/background.js`
### Actual Behavior
Actual logs seen on any web page:
`I'm a content script, and I'm going to try to send a message to anyone that is listening.`
Actual logs seen in terminal:
With the ELECTRON_ENABLE_LOGGING=1 env set, expected to see:
`[xxx:INFO:CONSOLE(1)] "Hello, I'm a service worker", source: chrome-extension:///<some_chrome_extension_id>/background.js`
### Testcase Gist URL
https://gist.github.com/schetle/8ea7451215b89c4cc28506f96e9f384a
### Additional Information
By January of this upcoming year, Manifest V2 extensions will cease to function (please see: https://developer.chrome.com/docs/extensions/mv3/mv2-sunset/)
Part of the migration process to get from a V2 -> V3 extension requires that background pages are replaced with service workers (please see: https://developer.chrome.com/docs/extensions/mv3/intro/mv3-migration/#background-service-workers)
