Access AngularJS constant in a view
Is not possible. You need to inject Urls in the controller $scope (or parent using $parent) because {{ var }} is interpolated to $scope.var
Does not have any performance problem if you inject Urls in your controller and write $scope.Urls = Urls
Example:
angular.module('myapp').controller('myController', ($scope, Urls) { $scope.Urls = Urls;}
