Command line tool

• I want to use sbt with scalajs-bundler (recommended)
• I want to use sbt without scalajs-bundler

The command line is the same functionality as the sbt plugin just without sbt. You provide a directory where you have installed javascript packages so it has a package.json and a node_modules, optionally change some conversion options, and then start the conversion.

The output is a set of locally published jar files which you can paste into sbt or your build tool of choice.

Running

The easiest way to run is with coursier's excellent runner.

1. Install the cs command with these instructions https://get-coursier.io/docs/cli-overview
2. Install the ScalablyTyped Converter (stc) cs install stc
3. Run stc (in a directory with package.json and node_modules)

Configuration

Usage: stc [options] [libs]  -h, --help -v, --version -d, --directory <value> Specify another directory instead of the current directory where your package.json and node_modules is --includeDev <value> Include dev dependencies --includeProject <value> Include project in current directory --useScalaJsDomTypes <value> When true (which is the default) uses scala-js-dom types when possible instead of types we translate from typescript in std -f, --flavour <value> One of normal, japgolly, slinky, slinky-native. See https://scalablytyped.org/docs/flavour --scalajs <value> Scala.js version --scala <value> Scala version --outputPackage <value> Output package --enableScalaJSDefined <value> Libraries you want to enable @ScalaJSDefined traits for. -s, --stdlib <value> Which parts of typescript stdlib you want to enable --organization <value> Organization used (locally) publish artifacts --ignoredLibs <value> Libraries you want to ignore libs Libraries you want to convert from node_modules 

Publishing

The command line tool used to support publishing to bintray, but that service shut down. As such, the flags -publish-to-bintray-repo and --publish-git-repo-link are now gone. If you want this to return, make some noise (or a PR) at https://github.com/ScalablyTyped/Converter/issues/262

Convert your Typescript project

If you happen to have a Typescript project, and you want to reuse parts of it for a Scala.js app without going through npm we've got you covered.

This can enable all sorts of cool use cases where you can gradually migrate to or test Scala.js.

1. Build your Typescript project with --declaration so that it generates .d.ts files
2. Run the cli tool from the project directory with --includeProject=true

Note, we use the name of the current directory as the library name. You might have to tell webpack where to actually find it.

Now what?
