alsotang/node-lessons ? reverse-engineered prompt

Build me a simple Node.js learning site for beginners, based on a set of numbered lessons. I want a clean home page that lists lessons 0 through 18, and each lesson should open a page with the lesson title, a short explanation, and any small practice code or examples for that topic. The lessons should cover things like setting up Node, Express, modules, crawling pages, testing, regex, deployment, MongoDB, cookies and sessions, promises, and middleware.

Make it feel like an easy to follow course, not a fancy product. Keep the layout simple and readable, with clear navigation between lessons. If it helps, use current Node.js best practices and look up current docs online for anything outdated, but still keep the spirit of the original course. I’d also like the project to be easy to run locally and organized so I can add more lessons later.
