Here are some list od modules :
1. http Module : The http module provides functionality to create an HTTP server and make HTTP requests. Below is an example of creating an HTTP server
2. fs Module : The fs module provides file system related operations. Here's an example of reading a file asynchronously
3. path Module : The path module provides utilities for working with file and directory paths. Below is an example of joining paths
4. os Module : The os module provides operating system-related utility methods. Here's an example of getting the CPU architecture
5. events Module : The events module provides an EventEmitter class that allows you to emit and listen for events. Below is an example of using EventEmitter
//Http module
const http = require('http');
const server = http.createServer((req, res) => {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello, World!
');
});
const PORT = 3000;
server.listen(PORT, () => {
console.log(`Server is running on port ${PORT}`);
});
//Fs module
const fs = require('fs');
fs.readFile('example.txt', 'utf8', (err, data) => {
if (err) {
console.error('Error reading the file:', err);
return;
}
console.log('File content:', data);
});
//Path module
const path = require('path');
const fullPath = path.join(__dirname, 'folder', 'file.txt');
console.log('Full path:', fullPath);
//Os module
const os = require('os');
console.log('CPU architecture:', os.arch());
//Event module
const EventEmitter = require('events');
class MyEmitter extends EventEmitter {}
const myEmitter = new MyEmitter();
myEmitter.on('event', (data) => {
console.log('Event data:', data);
});
myEmitter.emit('event', 'Hello, EventEmitter!');
