vinothkumar-cloud/BookStore ? reverse-engineered prompt

Build me a simple book store web app where people can browse books, see details for each one, and manage a small catalog.

I want a clean frontend where users can view a list of books, open a book page, and maybe add, edit, or delete books if they are an admin. The backend should handle saving the book data, getting it back, and talking to the frontend smoothly. Use a modern, simple design that feels easy to use on desktop and phone.

Please set it up as a full MERN app with a separate frontend and backend, and make sure the app works end to end with sensible default data so I can try it right away. If anything about the setup is unclear, use common best practices and look up current docs online if you need to.
