umairrahim914/mern-ecommerce-store ? reverse-engineered prompt

Build me a full stack online store where people can browse products, filter by category, add items to a cart, and sign in securely so their session stays protected.

I want the app to feel clean and modern, with a simple home page, product listing, product details, cart, and basic account login and signup. Use a backend with REST style endpoints, connect it to MongoDB, and make sure the data actually comes from the database instead of being hardcoded. The cart should update smoothly as items are added or removed, and the UI should react nicely without feeling clunky.

Please set it up as a working MERN app with a clear split between client and server, and make sure authentication is handled with JWT. If you need to check current docs for anything, go ahead and look them up online.
