sbt-web plugin that uses postcss-cli to run Autoprefixer to post-process CSS and add vendor prefixes to rules by Can I Use.
To use the latest version from Github, add the following to the project/plugins.sbt of your project:
lazy val sbtAutoprefixer = uri("git://github.com/gpgekko/sbt-autoprefixer")
lazy val root = project.in(file(".")).dependsOn(sbtAutoprefixer)Your project's build file also needs to enable sbt-web plugins. For example with build.sbt:
lazy val root = (project in file(".")).enablePlugins(SbtWeb)Declare the execution order of the pipeline:
pipelineStages := Seq(autoprefixer)Note: if dependency resolving breaks on org.webjars.npm.semver, add the following line to the project/plugins.sbt:
dependencyOverrides += "org.webjars.npm" % "semver" % "5.6.0"The following options are supported:
| Option | Description |
|---|---|
| browsers | Which browsers Autoprefixer will support. Default: > 1% in NL, last 2 versions, Firefox ESR |
| config | Contents of the config file. Use this if you want to fine tune the Autoprefixer configuration. Default: the browsers provided above |
The following sbt code illustrates how to set the browsers
browsers in autoprefixer := JS.Array("> 5%", "last 4 versions")To include just one CSS file for post processing
includeFilter in autoprefixer := GlobFilter("mystyle.css")
