Build me a full ecommerce app with an admin dashboard using React on the front end and Node, Express, MongoDB on the back end.

I want regular users to be able to sign up, log in, browse products, add items to a cart, place orders, and see their order history. I also want admins to have their own dashboard where they can add, edit, and delete products, manage inventory, and view basic store activity.

Please make authentication secure with JWT and protect the admin pages so normal users cannot access them. Use a clean responsive UI that works well on mobile and desktop, and keep the styling simple with Bootstrap. Set up the API, database models, routes, and middleware so the whole thing actually works end to end. If you need current library docs or best practices, feel free to look them up online.
