sbt-web plugin for brotli-compressing web assets using jbrotli bindings.
Rewritten from sbt-gzip sources, thanks to Typesafe/Lightbend. Some parts of code, docs, tests are copy-pasted with no changes.
Add the plugin to project/plugins.sbt (it must all be there and not build.sbt for plugin to initialize):
val brotliNativeArtefact = {
val osName = System.getProperty("os.name").toLowerCase
val osArch = System.getProperty("os.arch").toLowerCase
val family = if (osName.startsWith("linux")) {
"linux"
} else if (osName.startsWith("mac os x") || osName.startsWith("darwin")) {
"darwin"
} else {
"win32"
}
val arch = if (family == "darwin") {
"x86-amd64"
} else if (osArch == "i386" || osArch == "i486" || osArch == "i586" || osArch == "i686") {
"x86"
} else if (osArch == "amd64" || osArch == "x86-64" || osArch == "x64") {
"x86-amd64"
} else if (family == "linux" && osArch.startsWith("arm")) {
"arm32-vfp-hflt"
}
s"jbrotli-native-$family-$arch"
}
libraryDependencies ++= Seq(
"org.meteogroup.jbrotli" % brotliNativeArtefact % "0.5.0"
)
addSbtPlugin("com.github.enalmada" % "sbt-web-brotli" % "0.5.5")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)
As with all sbt-web asset pipeline plugins you must declare their order of execution e.g.:
pipelineStages := Seq(brotli)Include and exclude filters can be provided. For example, to only create
brotli files for .js files:
includeFilter in brotli := "*.js"Or to exclude all .js files but include any other files:
excludeFilter in brotli := "*.js"The '''default''' filters configured like this:
includeFilter in brotli := "*.html" || "*.css" || "*.js"
excludeFilter in brotli := HiddenFileFilter || "*.woff" || "*.woff2" || "*.gz"If you also using sbt-gzip, you may want configure it to ignore brotli-compressed files:
excludeFilter in gzip := "*.woff" || "*.woff2" || "*.br"This code is licensed under the Apache 2.0 License.
