# DevTools extension
|
|
|
|
To make debugging easier, Electron has basic support for
|
|
[Chrome DevTools Extension][devtools-extension].
|
|
|
|
For most devtools extensions, you can simply download the source code and use
|
|
the `BrowserWindow.addDevToolsExtension` API to load them, the loaded extensions
|
|
will be remembered so you don't need to call the API every time when creating
|
|
a window.
|
|
|
|
For example to use the [React DevTools Extension](https://github.com/facebook/react-devtools), first you need to download its
|
|
source code:
|
|
|
|
```bash
|
|
$ cd /some-directory
|
|
$ git clone --recursive https://github.com/facebook/react-devtools.git
|
|
```
|
|
|
|
Then you can load the extension in Electron by opening devtools in any window,
|
|
and then running the following code in the devtools console:
|
|
|
|
```javascript
|
|
require('remote').require('browser-window').addDevToolsExtension('/some-directory/react-devtools')
|
|
```
|
|
|
|
To unload the extension, you can call `BrowserWindow.removeDevToolsExtension`
|
|
API with its name and it will not load the next time you open the devtools:
|
|
|
|
```javascript
|
|
require('remote').require('browser-window').removeDevToolsExtension('React Developer Tools')
|
|
```
|
|
|
|
## Format of devtools extension
|
|
|
|
Ideally all devtools extension written for Chrome browser can be loaded by
|
|
Electron, but they have to be in a plain directory, for those packaged `crx`
|
|
extensions, there is no way for Electron to load them unless you find a way to
|
|
extract them into a directory.
|
|
|
|
## Background pages
|
|
|
|
Currently Electron doesn't support the background pages feature in chrome extensions,
|
|
so for some devtools extensions that rely on this feature, they may not work in Electron.
|
|
|
|
## `chrome.*` APIs
|
|
|
|
Some chrome extensions use `chrome.*` APIs for some features, there has been some
|
|
effort to implement those APIs in Electron, however not all are implemented.
|
|
|
|
Given that not all `chrome.*` APIs are implemented if the devtools extension is using APIs other than `chrome.devtools.*`, the extension is very likely not to work. You can report failing extensions in the issue tracker so that we can add support for those APIs.
