realtime

Real-time patterns: SSE with Redis Pub/Sub and heartbeat, Socket.IO with Redis adapter for multi-server, Supabase Realtime CDC, WebSocket reconnection with exponential backoff, choosing SSE vs WebSockets vs polling. Use when building live updates, notifications, collaborative features, real-time dashboards.

realtime

Core principles

SSE for server-to-client — simpler than WebSockets, auto-reconnects, HTTP/2 multiplexed

WebSockets for bidirectional — when client sends frequent messages (chat, multiplayer)

Redis Pub/Sub for multi-instance — events published on one server must reach all clients

Always heartbeat — detect stale connections; proxies and load balancers kill idle connections

Exponential backoff on reconnect — avoid stampede when server restarts
