selvavignesh978/ECommerce-Platform-Frontend-and-Backend-Integration ? reverse-engineered prompt

Build me a full stack e commerce app called Market & Co. with a React frontend and a Node, Express, MongoDB backend. I want users to be able to register, log in, browse products, search and filter them, open product details, add items to a cart, and place a simple cash on delivery order. Keep the cart and login state saved properly, show loading and error states, and handle expired logins cleanly.

Also add an admin area where an admin can manage products and update order status. Make the app feel polished and responsive, and include a contact form with validation. On the backend, use secure JWT login, password hashing, and role based access control. Add endpoints for products, orders, user profiles, and recommendations, with a fallback recommendation system if the external service is not available.

Use environment variables for the API URL and database settings, and make it ready to run locally with clear setup steps. If you need current docs for any library details, look them up online first.
