## Overview

This is a MERN e-commerce application: shoppers browse and review products, manage a cart or wishlist, check out, and track orders; administrators manage catalog, users, orders, and sales analytics. The client is routed through App and communicates with the Express API; controllers implement domain operations against Mongoose models. The sampled routes and controllers establish the server wiring and order, product, and user persistence. Other major features are retained based on the README and tree, though their exact internal calls were not sampled.

Main entry points: [`frontend/src/App.tsx`](https://github.com/emadelnagar/mern-ts-ecommerce/blob/main/frontend/src/App.tsx) (Application Router), [`frontend/src/API.ts`](https://github.com/emadelnagar/mern-ts-ecommerce/blob/main/frontend/src/API.ts) (HTTP Client), [`backend/src/index.ts`](https://github.com/emadelnagar/mern-ts-ecommerce/blob/main/backend/src/index.ts) (API Server), [`frontend/src/features/ProductFeatures.ts`](https://github.com/emadelnagar/mern-ts-ecommerce/blob/main/frontend/src/features/ProductFeatures.ts) (Product Actions)
