samagallaramya/ecommerce-web-application ? reverse-engineered prompt

Build me a full ecommerce web app where people can sign up, log in, browse products, and place orders.

I want a simple but polished shopping experience with a product list, product details, cart, checkout flow, and pages for user account and order history. Admin should be able to add, edit, and remove products, and manage orders. Please make the app work end to end with a React frontend and a Node and Express backend connected to MongoDB, with REST APIs for authentication, products, and orders.

Keep the UI clean and easy to use, and make sure the app handles loading states, form validation, and basic error messages. If you need to check current docs or best practices for anything, go ahead and look them up online.

Set it up so I can run the frontend and backend locally and it feels like a real starter ecommerce project I could build on later.
