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 is known for its high performance, low latency, and minimal overhead, making it a popular choice for building WebSocket-based applications.

Compared to alternative WebSocket libraries like socket.io, ws is more lightweight and focused specifically on WebSocket functionality without additional features like fallback mechanisms or broadcasting. ws is actively maintained with regular updates and bug fixes, ensuring compatibility with the latest Node.js versions.
