Depending on what you have in your addon
folder, you can access the app’s config.
For example if you have a Mixin that is used by some object in the consuming that is looked up via the container/resolver (like route, controller, component, view, etc) then you can lookup the app’s config like the following:
modulePrefix: Ember.computed(function() {
var applicationConfig = this.container.lookup('config:environment');
return applicationConfig.modulePrefix;
})
