Building Real-Time Apps with WebSockets 🚀

Short summary

WebSockets enable persistent bidirectional connections for real-time applications, replacing polling-based HTTP. Production systems require robust session handling, reconnection logic, graceful degradation, and horizontal scaling via load balancing and distributed messaging (Redis Pub/Sub).

• •WebSockets establish persistent connections for instant bidirectional data flow
• •Key challenges: session management, disconnection recovery, reliability, and graceful failure handling
• •Scale with load balancing, Redis Pub/Sub, and stateless server architecture
