Figwheel Helper Functions
The lein-figwheel template provides several helper functions in
dev/user.clj to start Figwheel and a Clojurescript REPL from a Clojure REPL.
In a development environment a Clojure REPL will start in
user namespace, so the functions in
dev/user.clj are available when you run a Clojure REPl in Spacemacs -
SPC m '
(ns user (:require [figwheel-sidecar.repl-api :as f])) ;; user is a namespace that the Clojure REPL loads if its available ;; Helper functions can also be added for starting and stopping a webserver or other development services (defn fig-start "This starts the figwheel server and watch based auto-compiler."  (f/start-figwheel!)) (defn fig-stop "Stop the figwheel server and watch based auto-compiler."  (f/stop-figwheel!)) ;; com.cemerick/piggieback is added as a :profile :dev :dependency to support an nREPL environment (defn cljs-repl "Launch a ClojureScript REPL that is connected to your build and host environment."  (f/cljs-repl))
You can use these Figwheel helper functions with Emacs & Cider (and Spacemacs) by adding the following function in your
init.el configuration file (or ~/.spacmacs file in the
(setq cider-cljs-lein-repl "(do (user/fig-start) (user/cljs-repl))")
When you run the Emacs command
cider-cljs-lein-repl name is evaluated and the two helper functions are run one after the other.
