Congratulations! I had a fun time making a little project with Htmx, though ultimately went with something else as I ended up heavily using a openlayers, and map libs are notoriously heavy with clientside javascript and Svelte ended up being a better tool for the job.
I plan on using it again for a future Golang project and look forward to following it's development. If you're in need of a simple/medium complex front end for your app, and _especially_ if you're already using template fragments[0], I really recommend giving HTMX a shot. It's pretty fun to work with coming from Javascriptland.
Also, the guy who runs their Twitter account[1] is hilarious.
