sakariyekaamil/mern_stack ? reverse-engineered prompt

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

I want a basic full stack starter that has a home page, a way to add and view data, and a simple API on the server side. Please wire up the frontend to talk to the backend, handle loading and error states, and make sure it runs easily from the root with clear setup steps. Use environment variables for anything sensitive and include a sample env file so I know what to fill in.

Keep the design clean and minimal, and make the code easy to understand and extend later. If you need to check current docs online for anything, go ahead.
