Facebook Developers

Back in September we launched FBJS for Facebook Platform. FBJS is a layer on top of Javascript that gives you the full power of Javascript in your applications. FBJS enables developers to create richer and more deeply integrated applications, with features like DOM manipulation and AJAX.

One caveat to FBJS, however, is that most 3rd-party libraries are incompatible, which makes things like animation a little bit tricky. So we decided to create an animation library for FBJS to help developers out. Unsatisfied with the state of 3rd-party animation libraries, we built our own animation library from scratch. We've been using this new animation library internally for several months for animations around Facebook, and everyone here has been very happy with it. Now we're ready to release it to developers on Facebook Platform so you can use it too.

And then we thought: "why stop there?" The library had very little Facebook-specific code, so we took some time to modularize it, and now we're open-sourcing it for everyone. The code is released under a modified BSD license, which means you're free to use it pretty much wherever you want.

So check out the documentation and enjoy! http://wiki.developers.facebook.com/index.php/FBJS/Animation.

For applications using FBML canvas pages and profile boxes, you can start using FBJS Animation immediately. If you want to use FBJS Animation outside of Facebook, grab the Javascript from our open source portal and include it on your site. After that, the syntax is exactly the same as it is on Facebook.
