Maybe a contrarian view, but as someone very knowledgeable about .NET API backends + angular on the frontend, I've found that HTMX made things more difficult as it required me to move back to mixing presentation concerns with business-logic and data concerns (basically have the backend produce the UI, which is whole point of HTMX). This is not a criticism but I suspect that the people enjoying HTMX are either people…
That's on you not on your platform
