# DevTools extension
|
|
|
|
To make debugging more easy, atom-shell has added basic support for
|
|
[Chrome DevTools Extension][devtools-extension].
|
|
|
|
For most devtools extensions, you can simply download their source codes 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, 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 it in atom-shell by opening the devtools in arbitray window,
|
|
and run this code in the console of devtools:
|
|
|
|
```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 disappear 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
|
|
atom-shell, but they have to be in a plain directory, for those packaged `crx`
|
|
extensions, there is no way in atom-shell to load them unless you find a way to
|
|
extract them into a directory.
|
|
|
|
## Background pages
|
|
|
|
Currently atom-shell doesn't support the background pages of chrome extensions,
|
|
so for some devtools extensions that rely on this feature, they may not work
|
|
well in atom-shell
|
|
|
|
## `chrome.*` APIs
|
|
|
|
Some chrome extensions use `chrome.*` APIs for some features, there is some
|
|
effort to implement those APIs in atom-shell to make them work, but we have
|
|
only implemented few for now.
|
|
|
|
So if the devtools extension is using APIs other than `chrome.devtools.*`, it is
|
|
very likely to fail, but you can report those extensions in the issues tracker
|
|
so we can add support for those APIs.
