HeyPuter/node.js-express.js ? reverse-engineered prompt

Build me a simple starter project that uses Node.js and Express with TypeScript, set up as a clean template for Puter.js.

I want it to run as a basic web app or API starter that I can open in the browser and extend easily. Please make sure the project is organized, easy to understand, and includes the usual setup so I can start coding right away without having to figure out the basics myself.

If it helps, add a simple example route and a small piece of Puter.js related integration or placeholder so I can see where that logic should go. Keep the code tidy, use sensible defaults, and make it feel like a real template I could clone and reuse.

If you need current details from the Puter.js docs to make the starter accurate, look them up online first.
