Lazy loaded 3rd party library

1

Hey. I am trying to import external js file in one of my application routes.

    @(task(function* () {
    yield import('jquery/dist/jquery').then(module => module.default);
    yield import('jquery-ui/ui/widget.js').then(module => module.default);
    yield import('jquery-ui/ui/widgets/mouse.js').then(module => module.default);
    yield import('jquery-ui/ui/data.js').then(module => module.default);
    yield import('jquery-ui/ui/ie.js').then(module => module.default);
    yield import('jquery-ui/ui/scroll-parent.js').then(module => module.default);
    yield import('jquery-ui/ui/version.js').then(module => module.default);
    yield import('jquery-ui/ui/widgets/sortable.js').then(module => module.default);
    yield import('jquery-ui/ui/position.js').then(module => module.default);
  })) pivotTableRunner;

  afterModel(){
    this.get('pivotTableRunner').perform();
  }

Currently I’ve been importing that library in my pivotTableRunner, but it turned out, that I have had to make some modifications of that library imported from node_modules. I copied it’s content to another file, and saved it in vendor folder. Is there any way to import it lazily after pivotTableRunner task?
