vineshpabbisetti/MERN ? reverse-engineered prompt

Build me a simple MERN learning project that shows how the front end, back end, and database work together.

I want a small full stack app with a clean interface where I can add, edit, delete, and view items. The app should save data in a database, load it on refresh, and show clear success or error messages when something goes wrong. Please set it up so the client and server are easy to run locally, with a straightforward folder structure and basic configuration I can follow.

Keep the code beginner friendly and leave a few comments where it helps explain what is happening. If you need to check current docs for anything, go ahead and look it up online. Also include simple setup steps so I can start it quickly and understand how the pieces connect.
