Install WebSocket Library:
First, you'll need a WebSocket library. is a popular choice. Install it using npm:

npm install

Create a WebSocket Connection:
In your Next.js component or page, create a WebSocket connection. For example, in a React component:

import { useEffect } from 'react';
import io from '';

const MyComponent = () => {
  useEffect(() => {
    // Replace 'your-backend-url' with the actual URL of your WebSocket server
    const socket = io('your-backend-url');

    // Handle events from the server
    socket.on('notification', (data) => {
      console.log('Received notification:', data);
      // Update your component state or trigger a notification UI

    // Clean up the socket connection when the component unmounts
    return () => {
  }, []);

  return (
      {/* Your component content */}
export default MyComponent;

Ensure that you replace 'your-backend-url' with the actual URL of your WebSocket server.

Backend Integration:
Ensure that your backend is set up to handle WebSocket connections. If you're using Node.js, you might have a setup similar to the following:

const httpServer = require('http').createServer();
const io = require('')(httpServer);

io.on('connection', (socket) => {
  console.log('A user connected');

  // Example: Send a notification to all connected clients
  setInterval(() => {
    socket.emit('notification', { message: 'Hello, this is a notification!' });
  }, 5000); // Send a notification every 5 seconds

  socket.on('disconnect', () => {
    console.log('User disconnected');

const PORT = process.env.PORT || 3001;

httpServer.listen(PORT, () => {
  console.log(`Server listening on port ${PORT}`);
