include bower component in Ember Controller

I am trying to use js-beautify in my ember application. The module is imported in app.import('bower_components/js-beautify/js/lib/beautify.js'); in ember-cli-build.js but i dont know how to use the beautify.js. how can i import the package in my controller? I tried something like this: import Ember from 'ember'; but with my bower_components/js-beautify/js/lib/beautify.js route but it refused to work.
