Using rails draper gem with angularjs and json

Question

so, I have seen people dancing around this topic, but I can't find the answer. I just installed the 'draper' gem with rails. It's great, but I want to be able to use it with angularjs. Is there a way to do that? Or do I need to just make a costum decorator in angularjs.... which would mean my 'draper' gem is useless:

class PageDecorator < Draper::Decorator
  delegate_all


 def emphatic
   object.text.upcase
 end

end

and my html is:

<li class="gregli" ng-repeat="page in pages">
  {{ page.text }}
</li>

and my rails controller is:

def index
    @pages = Page.all.decorate
    render json: @pages
end
