## What it is
Strophe.js is a dependency-free JavaScript/TypeScript library for building real-time XMPP applications, supporting XMPP over WebSockets (RFC 7395) and BOSH/HTTP (XEP-0124/0206). It provides stanza builders, multiple SASL mechanisms, stream management with session resumption, and runs in browsers, Node.js, and React Native.

## Use cases
- build a browser-based XMPP chat client
- connect to an XMPP server over WebSockets from JavaScript
- add real-time messaging to a web app
- resume XMPP sessions after dropped connections with stream management
- share a single XMPP connection across browser tabs
- authenticate to XMPP with SCRAM or other SASL mechanisms
- build a React Native chat app over XMPP

## When to choose
- you need XMPP support in JavaScript across browser, Node.js, or React Native
- you want a small, dependency-free client library with WebSocket and BOSH transports
- you need robust reconnection via XEP-0198 stream management
- you want modern TypeScript typings with ESM/CJS/UMD builds

## When to avoid
- your app does not use the XMPP protocol
- you need a full chat UI rather than a protocol library
- you require non-JavaScript environments or native mobile SDKs
