New experimental APIs for Chrome extensions
Montag, 4. April 2011
In the latest Chrome beta release, we made available two new
experimental extension APIs
: the Web Navigation and Proxy Extension APIs. They are the first in
a series of low-level APIs
that allow extension and application authors integrate more closely with the user’s browsing experience. We're excited about these APIs and want to get them in front of developers early so we can receive their feedback on any additional needs.
The
Web Navigation Extension API
allows extension developers to observe browser navigation events. These events fire both for top-level navigation and in-page navigation. The API therefore allows an extension to keep track of exactly what page (or section thereof) the tab is showing, and how the user got there. We foresee a number of use cases for this API, including extensions that gather and present statistical or benchmarking data, safe-browsing extensions, and developer tools.
The
Proxy Extension API
closes one of our most popular
feature requests
, allowing users to configure Chrome’s proxy settings via extensions. Proxies can be configured for the entire browser or independently for regular and incognito windows. Configuration options range from setting a single proxy server to installing remote or even local
PAC scripts
. A
sample extension
demonstrates these capabilities.

To try out these new APIs, please go to about:flags and enable “Experimental Extension APIs”. To protect our users' privacy, when these APIs reach the stable channel, extensions that use them will need to request explicit permission from users.
Let us know
if you create something cool with one of these APIs. If we like it, we may feature you in the extensions gallery.
We’re looking forward to seeing what you’ll create!
