Creating an HTTP Server

This feature allows you to create an HTTP server that listens on a specified port and hostname. The server responds with 'Hello, World!' to any incoming request.

const http = require('http');
const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello, World!');
});
server.listen(3000, '127.0.0.1', () => {
  console.log('Server running at http://127.0.0.1:3000/');
});

Making an HTTP GET Request

This feature allows you to make an HTTP GET request to a specified URL. The response data is collected and logged to the console.

const http = require('http');
http.get('http://www.example.com', (res) => {
  let data = '';
  res.on('data', (chunk) => {
    data += chunk;
  });
  res.on('end', () => {
    console.log(data);
  });
}).on('error', (e) => {
  console.error(`Got error: ${e.message}`);
});

Handling HTTP POST Requests

This feature allows you to handle HTTP POST requests. The server collects the POST data and responds with it.

const http = require('http');
const server = http.createServer((req, res) => {
  if (req.method === 'POST') {
    let body = '';
    req.on('data', chunk => {
      body += chunk.toString();
    });
    req.on('end', () => {
      res.end('Received POST data: ' + body);
    });
  } else {
    res.statusCode = 405;
    res.end('Method Not Allowed');
  }
});
server.listen(3000, '127.0.0.1', () => {
  console.log('Server running at http://127.0.0.1:3000/');
});
