Build Status

Strophe.js is a JavaScript library for speaking XMPP via BOSH (XEP 124 and XEP 206) and WebSockets (RFC 7395).

Its primary purpose is to enable web-based, real-time XMPP applications that run in any browser.

The book Professional XMPP Programming with JavaScript and jQuery covers Strophe in detail in the context of web applications.
