WebSockets provide a full-duplex communication channel over a single TCP connection. You can create a WebSocket server using the ws
library:
const WebSocket = require('ws');
const wss = new WebSocket.Server({ port: 8080 });
wss.on('connection', (ws) => {
ws.on('message', (message) => {
console.log(`Received: ${message}`);
});
ws.send('Welcome to the WebSocket server!');
});
