## Overview

FoodieHub is a full-stack food-ordering and restaurant-management application. Customers browse and search restaurants, manage favorites and a cart, check out with delivery details and coupons, then view orders; admins manage restaurants and order status. The React app routes users to these experiences and calls an Express API backed by MongoDB. The graph preserves the documented authentication, reviews, coupons and dashboard capabilities. Some feature pages and backend modules were not excerpted, so their internal call relationships are omitted where the evidence does not establish them.

Main entry points: [`frontend/src/App.jsx`](https://github.com/greeshmita-23/foodiehub-v2/blob/main/frontend/src/App.jsx) (App routes), [`backend/server.js`](https://github.com/greeshmita-23/foodiehub-v2/blob/main/backend/server.js) (API server), [`frontend/src/api/api.js`](https://github.com/greeshmita-23/foodiehub-v2/blob/main/frontend/src/api/api.js) (API client), [`frontend/src/pages/Checkout.jsx`](https://github.com/greeshmita-23/foodiehub-v2/blob/main/frontend/src/pages/Checkout.jsx) (Cart and checkout)
