Include node_module into Ember component

I am trying to add wavesurfer to my application. I did exactly according to the instructions. at: http://ift.tt/2y82gKw

After I did bower install I had wavesurfer.js folder inside my node_modules

import WaveSurfer from 'wavesurfer.js';

Theoretically WaveSurfer class should be available on my component. But after I include above code I have this error

Uncaught Error: Could not find module wavesurfer.js
at requireModule (loader.js:58)

at Registry.resolve [as resolver] (ember.debug.js:4437)
at resolve (ember.debug.js:2109)

I killed almost a week on this.

How can I make that class available for my component

Thanks
