Allows ESLint to be used from within sbt. Builds on com.typesafe:js-engine in order to execute eslint.js along with the scripts to verify. js-engine enables high performance linting given parallelism and native JS engine execution.

Usage:

Add dependency to sbt (along with the resolver to BinTray):

resolvers += Resolver.bintrayIvyRepo("sisyfos-digital", "sbt-plugins")
addSbtPlugin("se.sisyfosdigital.sbt" % "sbt-eslint" % "1.0.6")
    
Install eslint, either globally with npm:

```shell
npm install eslint -g

Or locally in your project with a package.json file:

{
  "devDependencies": {
    "eslint": "5.8.0"
  }
}

By default linting occurs at compile time as part of your project's eslint task. Both src/main/assets/**/*.js and src/test/assets/**/*.js sources are linted.

Options can be specified in accordance with the ESLint website and they share the same set of defaults. To set an option you can provide a .eslintrc file within your project's base directory.
