I too wrote something similar in Python a couple of years ago. BUT that's not the point. Your contribution is well documented and effectively shared with whomever might want to use it. That is of value to our community.
A few years ago, worked on something similar with Node, Redis and Cassandra... depending on the type of data a given site/resource was, it would either deliver the static content, or run a given node module/version to process and deliver the request... worked very well at scale.
That's exactly what it does do! Everything is served from the sqlar table inside the database. Is there a bit of the documentation that doesn't make that clear?
Maybe I'm missing something. I built a website and hand-rolled cms ten years ago leveraging PhP and SQLite that stores and serves the site and certainly allows full CRUD operations.
