Introduction to WebSockets

WebSockets provide a full-duplex communication channel over a single TCP connection, enabling real-time bidirectional communication.

Setting Up Socket.io

const io = require('socket.io')(3000);

Event Handling

Socket.io allows you to emit and listen for custom events between client and server in real-time.

Use Cases

  • Chat applications
  • Live notifications
  • Collaborative tools
  • Real-time dashboards

Best Practices

Handle reconnection logic, implement proper error handling, use namespaces for organization, and consider scalability with Redis adapters for multiple servers.
