Gtalk using Jabber web api needs BOSH server or not?

Question

I need to develop a web application using Jabber protocol for Gtalk and Facebook chat.

Something similar to "Gaim" but gaim is a desktop client application (https://support.google.com/talk/answer/24073?hl=en-GB).

What is the jquery api I can use?

Where ever I get the samples, I was able to see that some url need to be given something like ["http://myboshservice.com/http-bind"].

Does it mean that its mandatory for me to configure a proxy server?

I am new to this XMPP technology. Please help me understand the requirements and concept.

Answer 1

As far as I know, you can't establish a socket connection from Javascript. That means that the XMPP connection needs to be piggy-backed on top of either HTTP or Websocket. BOSH (described in XEP-0124 and XEP-0206) is a way to run XMPP on top of HTTP.

I believe Google Talk and Facebook Chat do not provide BOSH or Websocket endpoints, so you'd either need to run a proxy yourself or use their native APIs.
