I use figwheel through cider-jack-in-clojurescript daily. There are some useful steps here: https://github.com/bhauman/lein-figwheel/wiki/Using-the-Figwheel-REPL-within-NRepl#integration-with-emacscider

Also, I have a .dir-local.el and set (cider-cljs-lein-repl . "(start-figwheel)”) where start-figwheel is what starts my cljs connection. The function lives in the user namespace, which is also the init ns for my repl.
