Webpack does not know how to load CSS files from node_modules when using `noView`.

Simply using import 'nprogress/nprogress.css'; in the same file works fine. Loading CSS with require elements in a view works as well.

Expected/desired behavior:

import nprogress from 'nprogress';
import { bindable, noView } from 'aurelia-framework';
import {PLATFORM} from 'aurelia-pal';

nprogress.configure({ showSpinner: false });

@noView([PLATFORM.moduleName('nprogress/nprogress.css')])
export class LoadingIndicator {
  @bindable loading = false;

  loadingChanged(newValue) {
    if (newValue) {
      nprogress.start();
    } else {
      nprogress.done();
    }
  }
}

The above should work when nprogress has been installed as a dependency.

• What is the motivation / use case for changing the behavior? I would expect loading CSS files via the noView decorator to work.

Interestingly, it seems to work fine if I don't wrap it in PLATFORM.moduleName. Is that the expected behavior?

@AshleyGrant have you checked it with wp4? recently?

[obedm503]

@AshleyGrant why not just import it directly and let webpack take care of it?

import 'nprogress/nprogress.css';
