ExpressJs — Modular Routes

Separate routes into different files for cleaner, more maintainable code by using express.Router().

// routes/user.js
const express = require('express');
const router = express.Router();

router.get('/', (req, res) => res.send('User List'));
module.exports = router;

// index.js
const userRoutes = require('./routes/user');
app.use('/users', userRoutes);
