A Chrome Extension for YouTube Activity Feeds

Slave Jovanovski, an engineer at YouTube, has put together a Google Chrome extension that should be of interest to the YouTube API community. It’s called
YouTube Feed, and after installing and authenticating with your YouTube account,
it automatically will fetch your YouTube social activity stream (both
subscriptions and friends’ actions) while you use Google Chrome. When a new
event, like a YouTube friend uploading or commenting on a video, takes place,
the extension will notify you and provide details on the activity, as well as
links to view the actual video. You have control over which types of activities
you’d like to be notified about, as well as how frequently you’d like the
extension to check for updates.

While you’ll hopefully find the extension useful on its own merits,
the fact that the source code has been released as part of an open source project means that the extension’s code can serve as inspiration (or a
jumping off point) for writing your own JavaScript code that interacts with the
YouTube API. Curious as to how to use OAuth to authenticate YouTube accounts
from a Chrome Extension? Or request JSON data with a JavaScript callback? The
answers await you in the source code!
