Yes, the routing part isn’t covered by stock htmx but it can be shimmed server-side or client-side. The more “fundamental” bit as I understand it is that each logical/visible component is served by the server-side in a remix app as a separate, fully-rendered html component, instead of needing to render the entirety of the response to effectively obtain just a part of the view. Htmx provides that bit of the puzzle lending the remix-like aspect to a traditional server-side app.
