Build me a simple JavaScript backend for a web app.

I want it to run cleanly from the main entry file, keep the app code in src, and support basic API endpoints for storing and retrieving data. It should also handle file uploads since there’s an uploads folder already there, and serve those files back when needed.

Please set up the project so it’s easy to start, easy to extend, and has clear structure for routes, controllers, and any needed configuration. If you need to check current best practices or docs for anything, look them up online.

Make it work like a solid starter backend that I can connect to a frontend later.
