Build me a simple Node app that serves a public website and uses a local data folder to keep whatever content it needs.

I want a clean, easy to use site that loads from the public folder, with a small backend in server.js that handles the basic app logic and reads or writes data from the data folder. Make it feel like a finished project, not a demo, so the page should load properly, handle missing data gracefully, and show a useful empty state if there is nothing saved yet.

Keep the setup straightforward so I can run it locally without much fuss. If you need to check current best practices or look up anything, go ahead and do that. After building it, make sure the app starts without errors and the frontend actually works end to end.
