Building a Real-Time Chat Application with WebSockets in Node.js

In this tutorial, we will create a real-time chat application using Node.js and WebSockets. Real-time communication is a crucial aspect of modern web applications, allowing users to interact with each other instantaneously. By leveraging WebSockets, we can establish a persistent connection between the client and server, enabling seamless data exchange.

WebSockets provide a full-duplex communication channel over a single TCP connection, allowing both the client and server to send messages at any time. Unlike HTTP, WebSockets maintain a persistent connection, making them ideal for applications requiring real-time updates, such as chat apps, online gaming, and live notifications.

// Import required modules
const express = require('express');
const app = express();
const basicAuth = require('express-basic-auth');

// Define a user for basic authentication
const users = { 'username': 'password' };

// Use express-basic-auth middleware for authentication
app.use(basicAuth({ users }));

// Define a route accessible only to authenticated users
app.get('/secure', (req, res) => {
  res.send('Authenticated route');
});
