Node.js + Express + MongoDB Example

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

// Create Express app
const app = express();
app.use(express.json());

// Connect to MongoDB
mongoose.connect('mongodb://localhost:27017/api-db', {
    useNewUrlParser: true,
    useUnifiedTopology: true
});

// Define a simple route
app.get('/', (req, res) => {
    res.json({ 
        message: 'Backend with Database Running!',
        timestamp: new Date()
    });
});

// Start server
const PORT = process.env.PORT || 3000;
app.listen(PORT, () => {
    console.log(`Server running on port ${PORT}`);
});
