syed69/practical12-mern ? reverse-engineered prompt

Build me a simple full stack MERN app with a frontend and a backend that work together.

I want the app to let a user create, view, update, and delete items from a list, with the data saved in a database so it is still there after refresh. Make the frontend clean and easy to use, with a form for adding new items and a table or cards for showing the existing ones. Include basic editing and deleting too.

Set up the backend so it exposes the needed API endpoints and connects properly to the frontend. If you need to check current docs online for anything, go ahead. Keep the code organized and make sure it runs from the root project easily. I also want sensible error handling, loading states, and a README style note on how to start both parts locally.
