ZPusher Client

ZPusher Client (v1.0.9) is a WebSocket client library for connecting to ZPusher servers. It provides an event-driven API with automatic reconnection, channel subscription, and promise-based connection management. The library ships as a single JavaScript file supporting both Node.js and browser environments via script tag or npm. Key features include configurable auto-connect, reconnect timeout, and support for custom event listeners (open, close, error, reconnect). The package has no additional dependencies but requires a valid token and WebSocket endpoint. Compared to alternatives like Socket.IO, ZPusher is minimal and focused specifically on ZPusher server protocol.
