Node WebSocket Patterns

A guide to building real-time features using WebSockets in Node.js with connection management and scaling strategies.

Usage

Ask about WebSocket implementation, Socket.io, real-time features, or scaling WebSocket connections.

Examples

  • "Set up a WebSocket server with authentication"
  • "How do I implement rooms and broadcasting with Socket.io?"
  • "Scale WebSocket connections across multiple servers"

Guidelines

  • Implement heartbeat/ping-pong for connection health monitoring
  • Use rooms or channels for targeted message broadcasting
  • Authenticate connections during the handshake
  • Handle reconnection logic on the client side
  • Use Redis adapter for multi-server WebSocket scaling
