WebSockets in Production: Real-Time Features for Mumbai Apps

Implementing WebSocket-based real-time features for Mumbai client applications — chat, live updates, and collaborative editing.

WebSockets in Production: Real-Time Features for Mumbai Apps

Real-time features — live chat, order tracking, collaborative editing — require persistent connections that HTTP alone can't provide. WebSockets enable bidirectional communication between client and server with minimal overhead.

When to Use WebSockets

  • Live chat: Customer support, in-app messaging, consultation booking
  • Order tracking: Real-time status updates from "pending" through "delivered"
  • Collaborative tools: Document editing, whiteboarding, code collaboration
  • Live dashboards: Monitoring systems, stock tickers, analytics panels

Architecture

Client (Browser) ←→ WebSocket Connection ←→ Server (Node.js/ws) ↕ Redis Pub/Sub ↕ ↕ Server 2 Server 3

Production Considerations

Connection Management

  • Handle reconnection gracefully — browsers drop WebSocket connections on network changes
  • Implement exponential backoff: 1s, 2s, 4s, 8s... up to 30s max
  • Send periodic ping/pong frames to detect stale connections

Scaling

  • WebSocket connections are stateful — sticky sessions or a shared Redis pub/sub layer is essential for multi-server deployments
  • Consider Socket.IO (Node.js) or ActionCable (Rails) for production — they handle reconnection, rooms, and broadcasting out of the box

Mumbai Case Study

A Bandra-based logistics startup used WebSockets to provide real-time shipment tracking. Their Node.js server handles 5,000 concurrent connections on a single t3.medium instance. Customers see GPS-accurate delivery ETAs that update every 5 seconds.
