Still, please try shadow-cljs https://news.ycombinator.com/item?id=16866085 and join us on Slack.
However, shadow-cljs REPL integration was also pretty hard to get working with my editor (spacemacs), because most of the tutorials assume you're using lein to build your project.
shadow-cljs is pretty dope though. Almost instantaneous rebuild times and basically no setup besides a small, understandable config file.
