Hashir-Mehran/ShopMate ? reverse-engineered prompt

Build me a simple full stack shopping app called ShopMate with a customer side, an admin side, and a backend to connect them.

On the customer side, I want people to be able to browse products, view details, add items to a cart, update quantities, and go through a basic checkout flow. It should feel clean and easy to use on desktop and mobile.

On the admin side, I want a separate area where I can add, edit, and remove products, manage images, prices, stock, and see the current inventory at a glance.

Make the server handle the data for products, cart, and orders, and wire everything together so both the client and admin pages work smoothly. Use sensible defaults, nice styling, and make sure the whole thing is easy to run locally. If you need current library docs or examples, look them up online.
