Building RESTful APIs with Node.js

Introduction to REST APIs

REST (Representational State Transfer) is an architectural style for building web services. Let's build one with Node.js!

Setting Up Express

First, install the required packages:

npm install express

Creating Your First Endpoint

const express = require('express');
const app = express();

app.get('/api/users', (req, res) => {
  res.json({ users: [] });
});

app.listen(3000);

Best Practices

• Use proper HTTP status codes
• Implement error handling
• Validate input data
• Use middleware for authentication

Conclusion

Building REST APIs with Node.js is straightforward with Express. Follow these patterns for success!
