selvavignesh978/M5---End-to-End-MERN-Stack-ECommerce-Platform-Frontend-and-Backend-Integration ? reverse-engineered prompt

Build me a full e commerce app called Market & Co. with a React frontend and a Node, Express, MongoDB backend that all work together smoothly. I want shoppers to be able to sign up, log in, browse products, search and filter items, open product pages, see recommended products, add things to a cart, and place an order with cash on delivery. Please include secure JWT based login, password hashing, and a simple admin area where an admin can manage products and update order status.

Use a clean responsive UI, keep cart and login state saved properly, and make sure the frontend talks to the backend through real API calls with loading and error states. Also add a contact form with validation. If you need to check the latest setup details or best practices, look them up online. Make it easy to run locally with separate frontend and backend folders, and keep it ready for deployment.
