tudstk/mern-bookstore ? reverse-engineered prompt

Build me a simple MERN bookstore app with a clean frontend and a working backend.

I want a place where someone can browse a list of books, see basic details for each one, and manage the catalog from the app. Make it feel like a real bookstore site, with a simple home page, book list, book detail view, and forms for adding and editing books. If it makes sense, include search or filtering so people can find books easily.

Use the existing frontend and backend folders, wire everything together end to end, and make sure the app runs smoothly from local setup. Keep the design simple and modern, and if you need to check current docs for anything, feel free to look them up online.
