We've made an entirely new version of the devtools, and we want you to try it
|
|
|
|
|
out!
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
## Why entirely new? {#why-entirely-new}
|
|
|
|
|
|
|
|
|
|
Perhaps the biggest reason was to create a defined API for dealing with
|
|
|
|
|
internals, so that other tools could benefit as well and not have to depend on
|
|
|
|
|
implementation details. This gives us more freedom to refactor things
|
|
|
|
|
internally without worrying about breaking tooling.
|
|
|
|
|
|
|
|
|
|
The current version of the devtools is a fork of Blink's "Elements" pane, and
|
|
|
|
|
is imperative, mutation-driven, and tightly integrated with Chrome-specific
|
|
|
|
|
APIs. The new devtools are much less coupled to Chrome, and easier to reason
|
|
|
|
|
about thanks to React.
|
|
|

|
|
|

### Searching {#searching}
|
|
|
|
|
|
|
|
|
|
Select the search bar (or press "/"), and start searching for a component by
|
|
|
|
|
name.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### The Side Pane {#the-side-pane}

|
|

|
|
|
|

|
|

|
|
|
|
## How do I install it? {#how-do-i-install-it}
|
|
|
|
|
|
|
|
|
|
First, disable the Chrome web store version, or it will break things. Then
|
|
|
|
|
[download the .crx](https://github.com/facebook/react-devtools/releases) and
|
|
|
|
|
drag it into your `chrome://extensions` page. If it's not working to drag it
|
|
|
|
|
from the downloads bar, try opening your downloads folder and drag it from
|
|
|
|
|
there.
|
|
|
|
|
|
|
|
|
|
Once we've determined that there aren't any major regressions, we'll update
|
|
|
|
|
the official web store version, and everyone will be automatically upgraded.
|
|
|
|
|
|
|
|
|
|
### Also Firefox! {#also-firefox}
|
|
|
|
|
|
|
|
|
|
We also have an initial version of the devtools for Firefox, which you can
|
|
|
|
|
download from the same [release page](https://github.com/facebook/react-devtools/releases).
|
|
|
