Real Time Updates

1. Use WebSockets: Establish a persistent connection for real-time communication.

Example Client:

const socket = new WebSocket('ws://server.com');
socket.onmessage = (message) => console.log(message.data);

2. Server Setup: Use libraries like socket.io for WebSocket management.

Example Server:

const io = require('socket.io')(server);
io.on('connection', (socket) => {
  socket.on('chat message', (msg) => io.emit('chat message', msg));
});

3. Fallback for Compatibility: Implement long polling or server-sent events (SSE) if WebSockets aren't feasible.
4. Database Integration: Use event-driven solutions like Redis pub/sub for scalability in multi-server setups.
5. Security: Ensure secure WebSocket connections (wss://) and authenticate users.
