IsAmitprajapati/BlinkIt-Clone-Full-Stack-Ecommerce — reverse-engineered prompt

Build me a full stack grocery shopping website similar to Blinkit. I want customers to be able to browse products by category and subcategory, search or explore items, add things to a cart, and go through a normal ecommerce flow.

Please include user signup and login with secure authentication, access and refresh tokens, email OTP verification, and password recovery. I also need an admin area where an admin can upload products, manage products, manage categories and subcategories, and generally control what appears in the store.

Use a MERN style setup with a React frontend, Node and Express backend, and MongoDB database. Make it look clean and close to a modern quick commerce app, with responsive pages for mobile and desktop. Include sensible forms, loading states, error messages, protected routes, and basic seed or sample data so I can test it quickly.

If you need exact implementation details, look up current docs online and wire everything so it can run locally from client and server folders.
