asset-builder

A small utility to help with CLJS/JS/CSS asset building and minification.

Usage

Artifact Coordinates

Inclusion

I recommend adding a new profile containing all the things necessary for building - like ClojureScript dependencies - and activating it together with the :dev profile (for availability in the REPL):

:profiles
{:build {:dependencies [[org.clojure/clojurescript "1.7.107"]
                        [xsc/asset-builder "x.y.z"]]}
 :dev   [:build
         {:dependencies ...}]}

Builder

You can then create a new namespace build (e.g. at src/build.clj) and add the build logic:

(ns build
  (:require [asset-builder.core :as assets]))

(defn run
  []
  (assets/build
    {:cljs   {:source-paths ["src/cljs"]
              :output-to "resources/js/main.js"
              :output-dir "target/out"
              :optimizations :advanced}
     :assets {:source-path "resources/js"
              :target-path "resources/js"
              :minify
              {"external-script.js" "external-script.min.js"}}))

In the REPL, you can now run:

(require 'build)
(build/run)

Aliases

For automatic building (outside the REPL) you can add the following aliases (according to your requirements, of course):

:aliases
{"build"   ["with-profile" "+build" "run" "-m" "build/run"]
 "jar"     ["do" "build," "jar"]
 "uberjar" ["do" "build," "uberjar"]
 "install" ["do" "build," "install"]
 "deploy"  ["do" "build," "deploy"]}

Multiple Build Steps

asset-builder.core/build accepts any number of build specifications, running them in the order they are supplied, so you can do something like:

(assets/build
  {:cljs   {:output-to "resources/js/main.js", ...}}
  {:assets {:minify {"resources/js/main.js" "resources/js/main.min.js"}}})

Also, nil values are ignored, so you can have conditional build steps quite easily:

(assets/build
  (when (build? :cljs)
    {:cljs ...})
  ...)
