Clojurians Log v2

For this project https://github.com/oakes/odoyle-rum-todo It renders the html on the server then hydrates it on the client. I think thats the reason the setup is different. regardless they are calling figwheel/-main directly ... in order to get a editor repl integration with the fighweel server (e.g be able to re-eval cljs expressions like (inc 1)) should we be using figwheel sidecar instead? does that have to be used from lien?
