A lot of sources explain that for this you need to
- create a "File Watcher"-Job in the WebStorm-Settings (Tools)
 - define a "Scope" in WebStorm for the files you want to process
 - define a .babelrc file for configuration. Babel will use this automatically so you save some params in the call
 
{
  "presets": ["es2015", "react"],
  "plugins": ["transform-es2015-arrow-functions"]
}
npm install --save-devthe corresponding packages together with the babel-cli package.
BUT... how can I run the babel-Command on Windows when babel-cli module just delivers a "babel.js" file in its bin-folder? However Windows can only execute .exe, .bat or .cmd-files.
I tried to wrap the call in a cmd-script containing babel %* as I found a solution in one web article, but this did not work for me.
