What are the best practices for implementing WebSockets?

When implementing WebSockets, consider the following best practices: 1. Use a secure connection (wss://). 2. Implement proper error handling. 3. Keep the connection alive with ping/pong messages. 4. Use a message queue for handling messages efficiently. 5. Ensure scalability by using load balancers.

How do I handle reconnections?

To handle reconnections, implement an exponential backoff strategy. This means waiting longer between each reconnection attempt after a failure. Also, maintain the state of the application to resume operations smoothly after reconnection.

What security measures should I take?

For security, always use WSS (WebSocket Secure) to encrypt data. Implement authentication and authorization checks, and validate all incoming messages to prevent injection attacks.

Can you explain the ping/pong mechanism?

The ping/pong mechanism is used to keep the WebSocket connection alive. The server sends a ping message, and the client responds with a pong message. This helps detect broken connections and ensures that both ends are still active.
