Basic Socket.IO Implementation

Here’s how to create a basic Socket.IO server and client:

Server (server/index.js):

const express = require('express');
const http = require('http');
const { Server } = require('socket.io');

const app = express();
const server = http.createServer(app);
const io = new Server(server, {
  cors: {
    origin: "http://localhost:3000",
    methods: ["GET", "POST"]
  }
});

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

server.listen(4000, () => {
  console.log('Server listening on port 4000');
});

Client (src/App.js):

import React, { useEffect } from 'react';
import { io } from 'socket.io-client';

function App() {
  useEffect(() => {
    const socket = io('http://localhost:4000');

    socket.on('connect', () => {
      console.log('Connected to server');
    });

    socket.on('disconnect', () => {
      console.log('Disconnected from server');
    });

    return () => {
      socket.disconnect();
    };
  }, []);

  return (
    
      <h1>Real-Time Dashboard</h1>
    
  );
}

export default App;
