❓ FAQ
What's the difference between WebSockets and polling?
WebSockets maintain persistent connections with bidirectional data flow; polling requires repeated client requests. WebSockets are more efficient for high-frequency updates and lower latency.
Why does WebSocket scaling require special consideration?
WebSockets hold persistent connections consuming server memory and resources. Load balancing requires sticky sessions or distributed message brokers (Redis pub/sub) to sync state across instances.
When should I use Socket.io vs raw WebSocket?
Socket.io adds rooms, namespaces, and fallback protocols (polling); use it for rapid development. Raw WebSocket offers more control and lower overhead; use for ultra-high-performance applications.
How do I handle connection drops and reconnection?
Implement exponential backoff reconnection logic, queue pending messages, and validate state on reconnect. Socket.io handles this automatically; raw WebSocket requires manual implementation.
What's the role of message queues in real-time architectures?
Message queues (RabbitMQ, Kafka) decouple services, enable event broadcast across multiple servers, and provide durability when receivers are temporarily offline.
Can WebSockets scale to millions of connections?
Yes, but requires careful design: use load balancing, distributed brokers, and optimize per-connection memory. Enterprise solutions like Pusher/Ably handle scaling automatically.
What about security with persistent WebSocket connections?
Implement authentication before handshake, validate all incoming messages, use TLS/SSL (wss://), enforce rate limiting, and sanitize data to prevent injection attacks.
