sbt-web plugin with Google Closure Compiler integration

Scala versions: 2.10
sbt plugins: 0.13


Build Status

sbt-web plugin which integrates with Google’s Closure Compiler.


Add the plugin to your project/plugins.sbt:

addSbtPlugin("net.ground5hark.sbt" % "sbt-closure" % "0.1.4")

Add the Sonatype releases resolver:

resolvers += Resolver.sonatypeRepo("releases")

Enable the sbt-web plugin for your project:

lazy val root = (project in file(".")).enablePlugins(SbtWeb)

Add the closure task to your asset pipeline in your build.sbt:

pipelineStages := Seq(closure)

Configuration options

Option Description
suffix Suffix to append to each file compiled by closure. Defaults to ".min.js"
flags List of command line flags to provide to the closure compiler. Must be in the format of --option-name=value or --option-flag
parentDir Parent directory name where closure compiled JS will go. Defaults to "closure-compiler"

An example of providing options is below:

Closure.suffix := ".min.js"

Closure.flags := Seq("--formatting=PRETTY_PRINT", "--accept_const_keyword")

This will produce assets with the specified Closure.suffix suffix value under the Closure.parentDir directory within the target folder. This will be target/web/public/main or target/web/stage. For a full list of closure compiler options, see the official documentation page. You can also specify includeFilter in closure or excludeFilter in closure to select files on a custom criteria.
