New developer tools experimental APIs for Chrome extensions
Monday, October 3, 2011
Are you already a happy user of
Chrome Developer Tools
but always wanted that particular feature added to make you even more productive? Then we have some exciting news for you: our developer tools are now extensible!
You can now add new panels and sidebar section panes, retrieve network requests data, evaluate scripts on the page being inspected, and add custom audit rules.
The extension support is still experimental, but we wanted to let you know early, so we can incorporate
your feedback
before releasing the APIs.
Here’s how to get started with writing extensions for Chrome Developer Tools:
Use the
dev channel
of Chrome as the APIs are still under development;
Enable experimental extension APIs using the
chrome://flags
page;
List
experimental
in the permissions list of your extension;
Add a
devtools_page
field to your extension’s manifest, e.g:
{
"name": ...
"minimum_chrome_version": "14.0",
"devtools_page": "devtools.html",
"permissions": [ "experimental" ... ],
...
}
The developer tools extension pages get access to the chrome.experimental.devtools.* APIs which are described further in our
docs
. Be sure to check out the
sample extensions
, which include extensions for jQuery and FirePHP users and a simple audit extension that finds broken links.
For a richer example, you can also check out
Page Speed for Chromium
, which uses the extensions API to provide Page Speed suggestions right in the Chrome Devtools UI.
We’re looking forward to seeing your feedback on the APIs and, of course, cool extensions coming to life!
