WebSocket Best Practices

Connection

• Implement automatic reconnection with backoff
• Use heartbeat/ping-pong for connection health
• Handle connection state (connecting, open, closing, closed)
• Use secure WebSocket (wss://) in production

Patterns

• Use rooms/channels for topic-based messaging
• Implement pub/sub for broadcast
• Use acknowledgments for critical messages
• Use binary frames for large data
• Implement message queuing during disconnects

Scale

• Use Redis pub/sub for multi-server support
• Use sticky sessions or separate WS servers
• Implement horizontal scaling with message brokers
• Monitor connection counts and memory
