## What it is
xmpp.js is a modular JavaScript library implementing the XMPP (Extensible Messaging and Presence Protocol) for building chat clients and components. It runs universally across browsers, Node.js, React Native, Bun, Deno, and other JavaScript environments with automatic reconnection and a small footprint.

## Use cases
- build a chat application in the browser
- connect to an XMPP server from Node.js
- add real-time messaging to a React Native app
- write an XMPP bot or chatbot
- implement a server component that talks to an XMPP server
- send and receive presence and instant messages over XMPP

## When to choose
- you need XMPP support in JavaScript across multiple runtimes (browser, Node, React Native)
- you want a small, modular client library with automatic reconnection
- you're building chat, presence, or real-time messaging features on open standards

## When to avoid
- you need a ready-made chat UI rather than a protocol library
- your messaging needs are better served by WebSockets or a proprietary SDK like Firebase
- you require a non-JavaScript language runtime
