While I love both Go and Alex, my experience with HTMX has always ended up being disappointing.
I think the best way to put it, when I'm working with HTMX it feels like the complexity of the codebase is growing at a 2:1 rate compared to the app itself. I always end up with some weird edge case that I can not come out of without some weird hack.
I get why people dislike Node packages, HTMX feels like it's an overcompensating response to that. But the time you save by not having to wrestle with JSON is tripled when you try to make the app actually look or feel good. It takes me 2 minutes to slap together a Mantine template [1] and tap into some of the best UI components, then I can embed the built static assets and end up with the same single Go binary.
What's an example of a UI that you built with Mantine that you couldn't with htmx?
