  [scalablyTyped](https://github.com/lolgab/mill-scalablytyped)

  Provides the `ScalablyTyped` module, which on initialization scans `package.json` and `node_modules`, 
  converts any libraries found to scala.js facades, and adds them to ivy's local cache and `ivyDeps`.

  Notable Configs: 
    scalablyTypedBasePath = os.pwd
    scalablyTypedIgnoredLibs = [], 
    scalablyTypedFlavour = Flavor.Normal
