/** How do we use webpack to handle static files?
 *
 * - dependencies (js, scss, and css) are installed via npm
 * - dependencies (js, scss, and css ) are moved to `vendor.(js|css)`
 *   by specifing them in the vendor entry point
 * - everything else (our js, scss) is compiled into app.(js|css)
 * - our images, fonts, icons, js, css and scss is either in each apps
 *   static folder (/euth/<appname>/static) or in the projects asset folder
 *   (/euth_wagtail/assets)
 * - after running webpack all static ressources will be in the
 *   project static folder (/euth_wagtail/static) and can then be served
 *   by django
 * - webpack compiles jsx+es2015 to js and scss to css for us
