accchinhtraaccbo-cpu/severapp ? reverse-engineered prompt

Build me a simple Node.js server app that can run on Render.

I want a clean backend starting point with one main server file, a package setup that starts the app normally, and basic handling for a health check plus a simple API route or two so I can confirm it’s working. Make it easy to run locally and deploy without extra fuss. If there’s anything needed for production, set it up sensibly so it listens on the right port and doesn’t crash when deployed.

Keep the project lightweight and readable, and if you need to check current best practices for deploying a Node server on Render, look them up online. After you build it, make sure it starts successfully and give me a brief note on how to run it locally and deploy it.
