How do I connect to Facebook chat using Username/Password auth option and successfully send a message in either Javascript or Ruby?

Question

I have tried using the node-xmpp package and blather gem. I got the furthest with blather, but succeeded with neither.

From the Facebook API Docs:

Authenticating with Username/Password

The DIGEST-MD5 SASL mechanism is available to support traditional XMPP or multi-protocol IM clients that are not customized for (or even aware of) Facebook. This mechanism requires prompting the user for his or her password; therefore, it should only be used when necessary. In particular, it MUST NOT be used for any client that:

• Proxies the XMPP connection (the connection must be directly from the user's computer to Facebook).
• Reports messages or any other information about user activity to a third party (including the client developer).
• Integrates with Facebook, or has a Facebook Application ID. If your application does any of the above, you must use Facebook Platform authentication instead.

I think your application is doing one of the following, correct me if I'm wrong but based on the links you provided for your blather and node-xmpp issues I think you may be trying to violate the third criteria.

• Integrates with Facebook, or has a Facebook Application ID. If your application does any of the above, you must use Facebook Platform authentication instead.
