Request Lifecycle (One-Line per File)

1. client → server.js
   node server.js → Starts server, loads .env, runs app.

2. server.js → app.js
   const app = express(); → Initializes Express & middleware.

3. app.js → routes/
   app.use('/api', userRoutes) → Mounts API endpoints.

4. routes/ → controllers/
   router.get('/users', getUsers) → Maps routes to controllers.

5. controllers/ → models/
   User.find() → Runs business logic and queries DB.

6. models/ → database
   mongoose.model('User', schema) → Defines schema & queries DB.

7. app.js & controllers/ → middleware/
   app.use(authMiddleware) → Auth, error handling, logging.

8. models/ → config/
   mongoose.connect(DB_URI) → Connects to DB using env config.
