Allen Pike “after about a decade away from regularly writing JavaScript” comes back to take a look. I think these points are all correct: The goal was to see if there was an obvious (boring, trodden) framework, and the answer is… kinda?

There are quite a few tools to avoid *needing* a database these days, static site generators chief among them. So then what are the things that push toward or require a database?
