AngularJS use constant in directive -

i have defined constant this:

app.constant('ngsettings', {     apibaseurl: 'https://url/' }); 

how can reference constant in directive?

where directive this:

angular.module('my.directive', []).directive(................... 

you can inject constant anywhere injectable including directive definition itself, controller of directive, link function, et. al.

angular.module('my.directive', []).directive('name', ['ngsettings', function (ngsettings) {     // things ngsettings     return {}; }]); 

by way wouldn't name define ng -- should preserved things in ng module or angular created.
