@jannotabamo the thing is that you are using Angular 6 while using the official versions of nativescript-angular and nativescript-dev-webpack. The support for Angular 6 is coming with NativeScript 4.1. Meanwhile either use Angular 5.x.x with the official version of nativescript-angular and nativescript-dev-webpack(as done https://github.com/NickIliev/nativescript-ng-cosmos/blob/master/package.json) or use Angular 6 with nativescript-angular@next and nativescript-dev-webpack@next (for testing purposes and with all related dependencies updated as done here)
