## Overview

This is an Express restaurant/food API: users register or log in, then authenticated requests manage profiles and restaurant/catalog data; the food routes also define ordering and order-status operations. The visible runtime entry point mounts authentication, user, restaurant, and category routes, but not the food or test routes. Controller and model details are only sampled for some areas; the tree lists no category model or order model file, so their persistence wiring is not represented.

Main entry points: [`index.js`](https://github.com/mayanksingh-7974/restaurant-app/blob/main/index.js) (Express app), [`middlewares/authMiddleware.js`](https://github.com/mayanksingh-7974/restaurant-app/blob/main/middlewares/authMiddleware.js) (Auth middleware), [`routes/foodRoutes.js`](https://github.com/mayanksingh-7974/restaurant-app/blob/main/routes/foodRoutes.js) (Food routes), [`routes/userRoutes.js`](https://github.com/mayanksingh-7974/restaurant-app/blob/main/routes/userRoutes.js) (User routes)
