Pretty neat. Figwheel is pretty new to me, so it's something I'll have to look into.<p>I just recently got my head around using ClojureScript with vim-fireplace and Austin. It took a bit of work, but I finally got to a point where I easily have a browser REPL running using an environment stored in a var. This helps avoid security error, but it's not as simple a setup.<p>I suppose one big difference is the HTML I am using is being served via a Ring-based server rather than using a separate serving process. This allows me to add middleware in development mode that will inject the necessary JavaScript to connect to the browser REPL.
