XMPP is an open technology for real-time communication, which powers a wide range of applications including instant messaging, presence, multi-party chat, voice and video calls, collaboration, lightweight middleware, content syndication, and generalized routing of XML data.


xmpp.js is a JavaScript library for XMPP.



It aims to run everywhere JavaScript runs and make use of the best network transport available.


By default, it handles errors and will automatically reconnect. With appropriate configuration it will even loop through a list of endpoints. You don’t have to write a single line of code to handle network failures.

Releases follow the Semantic Versionning specification


Thanks to lerna, xmpp.js is highly modular, each feature is implemented as a plugin and can be included or excluded. (even XMPP core features)

This allows to hand-pick what you need and reduce browser bundle. Additionally plugins can be dynamically imported on demand.

For now the list of plugins is limited but will be completed over time.


Written in ES2015, it provides a modern promise based API and will keep up with meaningful additions to the standard.


xmpp.js is a rename and rewrite of the node-xmpp project and learned a lot from it.

Thanks to all xmpp.js and node-xmpp contributors.
