Build me a simple MERN CRUD app with a clean frontend and a backend that talks to a database. I want to be able to add new records, see them in a list, edit existing ones, and delete them. Keep the UI simple and easy to use, with a form for creating and updating items and clear buttons for saving and removing.

Please set up both the frontend and backend so they work together out of the box. Make sure the app shows helpful success and error messages, and handles loading states nicely. If you need to check current docs online for any setup details, go ahead. I also want the code organized in a way that is easy to understand and extend later, with sensible defaults and no unnecessary complexity.
