Node.js - HTTP Module

What is wrong with this Node.js code snippet that tries to read JSON data from the request body?

const http = require('http');
const server = http.createServer((req, res) => {
  const data = req.body;
  res.end(data);
});
server.listen(3000);

Ares.end cannot send data

Breq.body is undefined without parsing the data

Creq.body is a function, not a property

DMissing require for http module

Step-by-Step Solution

Solution:

Step 1: Understand how request body works in Node.js
In Node.js core, req.body is not automatically populated. You must collect data chunks and parse them manually or use middleware.
Step 2: Identify the error in the code
The code tries to access req.body directly, which will be undefined, causing the response to send undefined.
Final Answer:
req.body is undefined without parsing the data -> Option B
Quick Check:
req.body needs manual parsing [OK]

Quick Trick: req.body is empty unless parsed manually or with middleware [OK]
