Examples

Watch the directory tree:

import io.scalajs.JSON
import io.scalajs.nodejs.fs.Stats
import io.scalajs.npm.watch._
import scalajs.js

Watch.watchTree("./node_modules", new WatchOptions(), (files: js.Dictionary[Stats], current: Stats, prev: Stats) => {
  files foreach { case (file, stat) =>
    println("file '%s' (%d bytes)".format(file, stat.size.toLong))
  }
})

// unwatch the the tree
Watch.unwatchTree("./node_modules")

Artifacts and Resolvers

To add the Watch binding to your project, add the following to your build.sbt:

libraryDependencies += "io.scalajs.npm" %%% "watch" % "0.5.0"

Optionally, you may add the Sonatype Repository resolver:

resolvers += Resolver.sonatypeRepo("releases")
