Customize webpack.js build file to compile files to work with my Cordova app

Hi, I build an App with https://framework7.io. There is a webpack file to build it all. That works. See attachment. But when running "npm run build" it doesn't compiles it all correctly to the Cordova for some reason, because it's not showing the latest version; just a outdated one. Don't reply when no experience with Webpack or Cordova. VueJS experience is a pro.
