SadeepaAmaranayake/eCommerce-marketplace ? reverse-engineered prompt

Build me a full stack e commerce marketplace demo with a clean modern UI and a working backend.

I want users to be able to register, log in, browse products, search and filter them, view product details, add items to a cart, manage quantities with stock checks, save delivery addresses, place a simple checkout order, and see their order history. Also include editable profile details, reviews, wishlists, categories, coupon support, and image uploads for products.

On the admin side, I want a basic dashboard where an admin can manage products, categories, orders, users, and see simple stats and low stock warnings. It should also support payment setup for demo payments and a cash on delivery flow.

Use React for the frontend and Node with Express and MongoDB for the backend. Make sure authentication uses JWT, protected routes work properly, and the app feels responsive with nice feedback like toasts. If you need current package or API details, look up the latest docs online.
