The http module in Node.js is a built-in core module that allows you to create an HTTP server — no extra libraries required. It’s perfect for learning how Node.js handles web traffic under the hood.

🧠 Basic Concepts

• It’s lower-level than Express.

• You manually handle requests and responses.

• Great for learning how servers work!

✅ Step-by-Step: Create a Basic HTTP Server

📄 app.js

js
const server = http.createServer((req, res) => {  const server = http.createServer((req, res) => {  const server = http.createServer((req, res) => {  const server = http.createServer((req, res) => {  chunk => {      body += chunk.toString();    });        req.on('end', () => {      console.log('Received:', body);      res.end('Data received');    });  } else {    res.end('Send a POST request');  }});

🔥 Why Use http Module?

• To learn the internals of how web servers work.

• When you need full control over request/response handling.

• Lightweight or custom server needs.

But for real-world apps, people usually switch to Express.js for convenience.
