node-bosh-xmpp-client

node-bosh-xmpp

Motivation

Are you using node-xmpp for XMPP? But get blocked by coorperate firewalls? Then node-bosh-xmpp is API compatible with node-xmpp and gives you the ability to use XMPP over a standard HTTP port.

Credits go to Anoopc

I was looking for a BOSH XMPP client for node and came accross Anoop's node-xmpp-via-bosh implementation. His code was not completely working for me so I forked his code and fixed the issue I was having. I wanted to be able to specify the URL of the BOSH server and I also had some issues with the authorization proces.

Installation instructions

npm install node-bosh-xmpp-client

Code instructions

Following you will find the documentation from Anoop which I updated to reflect my changes:

It is inspired by node-xmpp (https://github.com/astro/node-xmpp) and xmppjs(http://github.com/mwild1/xmppjs) and it is API compatible with node-xmpp (except for the constructor).

It is an xmpp library which lets you establish a persistent session to xmpp server via a bosh-server and communicate willingly.
