Build me a simple full stack app that lets a user manage a basic list of records from a clean web page.

I want the frontend to let someone add new items, see them in a list, edit them, and delete them easily. The backend should save the data properly and expose the needed API endpoints so the app works smoothly end to end. Use a straightforward modern JavaScript setup, keep the UI simple and easy to understand, and make sure the app runs without a lot of extra setup.

If you need to check current docs or best practices while wiring it up, feel free to look them up online. Also include clear startup steps so I can run the frontend and backend locally and test everything right away.
