How to use Socket.IO in Node.js
Monday, January 12, 2026
Real-time bidirectional communication requires WebSockets, but handling browser compatibility and reconnection logic manually is complex. As the creator of CoreUI, I’ve built numerous real-time features with Socket.IO. Socket.IO is a library that provides WebSocket functionality with automatic fallbacks, reconnection, and room-based broadcasting. This approach simplifies real-time communication compared to native WebSockets while adding powerful features like namespaces and middleware.
