## Overview

This MERN storefront supports browsing a product list, viewing product details, and adding an in-stock quantity to a cart. The frontend routes screens and uses Redux actions/reducers for product and cart state; the backend exposes product-list and product-detail reads backed by MongoDB. The README provides no capability details, and several source files were not sampled, so uncertain cart persistence and other backend operations are not shown as connected flows.

Main entry points: [`frontend/src/App.js`](https://github.com/faixanpervaix/react-ecommerce/blob/main/frontend/src/App.js) (App Router), [`frontend/src/actions/productActions.js`](https://github.com/faixanpervaix/react-ecommerce/blob/main/frontend/src/actions/productActions.js) (Product Actions), [`backend/server.js`](https://github.com/faixanpervaix/react-ecommerce/blob/main/backend/server.js) (Express Server), [`frontend/src/store.js`](https://github.com/faixanpervaix/react-ecommerce/blob/main/frontend/src/store.js) (Redux Store)
