Clojurescript†

Config setting†

Delete cljs option comment in _config.clj, and add cljs compiler.

{
 ;; clojurescript compile options
 ;; src-dir base is `:template-dir`
 ;; output-dir base is `:public-dir`
 :cljs {:src-dir       "cljs"
        :output-to     "js/main.js"
        :optimizations :whitespace
        :pretty-print  true}

 ;; add cljs compiler
 :compiler ["default" "cljs"]
 }

Following is default cljs options, so you can specify only difference.

{
 :src-dir       "cljs"
 :output-to     "js/main.js"
 :optimizations :whitespace
 :pretty-print  true
 }
