ws is a simple and efficient WebSocket implementation for Node.js and the browser. It provides a straightforward API for creating WebSocket servers and clients, enabling real-time communication between the server and clients over a persistent connection. ws supports the latest WebSocket protocol versions and offers features like automatic reconnection, permessage-deflate compression, and custom extensions.

Compared to alternative WebSocket libraries like socket.io, ws is lightweight and focused specifically on WebSocket functionality, making it a preferred choice for projects requiring low latency and high performance WebSocket communication.
