I used htmx with Clojure and it was easy to mimic components as functions that return hiccup. I have a default middleware that converts it to html before sending it to the client unless I explicitly say it's a json route.

    (defn some-component [{:keys [class]} & children]
      [:div {:class (str "some-component-wrapper" class)}
       [:h1 "Hello World"]
       children])
