## Overview

This is a React storefront: users browse and filter products, open a product detail, add items to a shared cart, and navigate to checkout. React Router selects the page components; product data is fetched from Fake Store API, while Redux holds cart state. The tree also includes home, about, contact, and login pages. Source excerpts establish the catalog and cart wiring; details of unsampled pages and checkout behavior are limited to their presence and routes.

Main entry points: [`src/App.js`](https://github.com/hamza0718/shopping_cart/blob/main/src/App.js) (App Router), [`src/components/Product.js`](https://github.com/hamza0718/shopping_cart/blob/main/src/components/Product.js) (Product Detail), [`src/redux/store.js`](https://github.com/hamza0718/shopping_cart/blob/main/src/redux/store.js) (Redux Store), [`src/components/Cart.js`](https://github.com/hamza0718/shopping_cart/blob/main/src/components/Cart.js) (Cart Page)
