## What it is
StanzaJS is a JavaScript/TypeScript library for modern XMPP that exposes all stanzas as JSON instead of XML. It supports WebSocket and BOSH transports, Jingle/WebRTC signaling, PubSub, stream management, and plugin creation.

## Use cases
- build an xmpp chat client in javascript
- send and receive xmpp messages without touching xml
- add webrtc jingle calls to a web app
- connect to xmpp from react native
- implement pubsub messaging over xmpp
- create a browser-based chatbot over xmpp

## When to choose
- you need XMPP in JavaScript/TypeScript with a clean JSON API
- you want browser, Node.js, or React Native XMPP support
- you need Jingle/WebRTC or PubSub over XMPP

## When to avoid
- you need a non-XMPP chat protocol like Matrix or MQTT
- you require direct low-level XML stanza manipulation
- you need a ready-made chat UI rather than a protocol library
