Setup:

1. Create a new directory: mkdir my-api && cd my-api
2. Initialize the project: npm init -y
3. Install Express: npm install express

Create server.js:

javascript

Copy code

const express = require('express');
const app = express();
const PORT = 3000;

app.use(express.json());
app.get('/api/items', (req, res) => res.json([{ id: 1, name: 'Item 1' }]));
app.listen(PORT, () => console.log(`Server running on http://localhost:${PORT}`));

Test with Postman using GET /api/items. Happy coding!
