Facebook JavaScript SDK

This repository contains the open source JavaScript SDK that allows you to utilize Facebook on your website. Except as otherwise noted, the Facebook Connect JavaScript SDK is licensed under the Apache Licence, Version 2.0 (


This is an beta release. In order to guide the development of the library and allow you to freely inspect and use the source, we have open sourced the client JavaScript SDK.


We have made API documentation available for the public APIs here. In addition, the code itself contains full documentation for the private APIs if you want to study the internals.

We have a list of FAQs that detail some of the changes and provide information about the new SDK.

We are maintaining a changelog as we update the SDK. Since this is an Beta SDK, we might need to break compatibility between releases if the need arises.

The repository also contains simple examples showing the use of the SDK with popular JavaScript libraries such as Dojo, jQuery, MooTools, Prototype and YUI.


We are working hard to ensure your experience using the SDK is stable. In order to keep us nimble and allow us to bring you new functionality, without compromising on stability, we have ensured full test coverage of the new SDK. We are including this in the open source repository to assure you of our commitment to quality, but also with the hopes that you will contribute back to help keep it stable. The easiest way to do so is to file bugs and include a test case.


We are relying on the GitHub issues tracker linked from above for feedback. File bugs or other issues here.
