Router Organization
Organize routes into modular routers for scalable API structure
javascript
// routes/users.js
const express = require('express');
const router = express.Router();
router.get('/', getAllUsers);
router.get('/:id', getUserById);
router.post('/', createUser);
router.put('/:id', updateUser);
router.delete('/:id', deleteUser);
module.exports = router;
// app.js
app.use('/api/users', require('./routes/users'));
app.use('/api/products', require('./routes/products'));💡 Separate routes by resource or feature for maintainability
📌 Use router.route() to chain methods for same path
⚡ Mount routers with prefixes: app.use('/api/users', userRouter)
🟢 Essential for large applications - keeps code organized
