shivapriyabagari/sample_mern_app1 ? reverse-engineered prompt

Build me a simple MERN sample app that shows a basic end to end flow, with a React frontend, a Node and Express backend, and a MongoDB data model. I want it to feel like a small real app, not just a blank starter, so please include a clean homepage, a simple form, and a list view that can create, read, update, and delete one kind of record. Keep the UI straightforward and easy to use.

On the server side, set up the routes and models cleanly, connect to MongoDB, and make sure the frontend talks to the API properly. If anything in the current setup looks outdated, use the latest docs online and make reasonable choices. Please wire everything together so I can run it and see the full app working without extra manual setup.
