I believe my previous statement up there settles this issue. The author is asking us to ditch other options and focus on HTMX but he hasn’t articulated the areas where HTMX falls short.
We had a good AMA early this year on HTMX with Mark Volkman and he mentioned areas where HTMX falls short.
You should check it out. HTMX may be a great tool but it won’t solve everything and failing to point that out while asking people to ditch other tools is not a very good idea.
