Getting Started with Node.js for Beginners

What is Node.js? Node.js is an open-source runtime environment that executes JavaScript code outside of a browser, enabling server-side development using JavaScript.

Setting Up Node.js To get started:

• Download and install Node.js from the official website.
• Verify installation using the command node -v.

Creating Your First Server Use the following code snippet to create a simple HTTP server:

const http = require('http');

const server = http.createServer((req, res) => {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    res.end('Hello World\n');
});

server.listen(3000, () => {
    console.log('Server running at http://localhost:3000/');
});

Exploring npm (Node Package Manager) npm allows you to install libraries and packages easily. Use npm install <package-name> to add dependencies to your project.

Conclusion Node.js opens up new possibilities for web development by allowing JavaScript on the server side. Start building powerful applications today by exploring its capabilities!
