sbt-web plugin that uses 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 root = project.in(file(".")).dependsOn(sbtAutoprefixer)
lazy val sbtAutoprefixer = uri("git://github.com/mkurz/sbt-autoprefixer")
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 asset pipeline:
pipelineStages in Assets := Seq(autoprefixer)
The following option are supported:
Option | Description |
---|---|
browsers | Specify browsers versions. Default: empty |
cascade | Creates nice visual cascade of prefixes. Default: true. |
sourceMap | Enables source maps. Default: true. |
inlineSourceMap | Enables inline source maps by data:uri to annotation comment. Default: false. |
The following sbt code illustrates how to include inline source maps
AutoprefixerKeys.inlineSourceMap in Assets := true
To include all CSS files for post processing
includeFilter in autoprefixer := GlobFilter("*.css"),
You also have to use npm in order to install required dependencies. Modify your package.json (in root):
{
"dependencies": {
"autoprefixer": "^6.3.0",
"postcss-cli": "^2.5.0"
}
}
or invoke:
npm install postcss-cli@">=2.5.0" autoprefixer@">=6.3.0" --save
If you receive duplicate map errors when using incombination with LESS, turn sourceMapping off.
