# Building REST APIs with Node.js Node.js excels at handling asynchronous events, making it a perfect choice for building scalable RESTful APIs. ## Why Node.js? - **JavaScript Everywhere**: Use the same language on client and server. - **Express Middleware**: Simplify routes and API handling. - **Active Ecosystem**: Leverage thousands of npm packages for added functionality.
## Basic API Example ```js const express = require('express'); const app = express(); app.get('/api/users', (req, res) => { res.json({ message: 'Hello World' }); }); app.listen(3000, () => { console.log('Server started on port 3000'); }); ``` With Node.js and Express, it’s straightforward to set up routes, handle requests, and respond with JSON data—ideal for modern web applications.
