Please do a write up of the best practices you've found. I tried htmx a few years ago for a side project and while I appreciated the simplicity of a lot of it, I had trouble understanding how/when to use it and in what ways. I think I was trying to contort it too much into my understanding of api/spa. That or my interactivity needs were too complex for it, I can't tell.

These days, I admit, though, the ship has sailed for me and htmx. My main app frontend is React and since the LLMs all know much more than I do about how to build out UIs and are 100x faster than me, I'll probably be sticking with React.
