Inject dateFilter in a service in AngularJs

Question

First you have to inject the filter like this:

app.factory('myService', ['$rootScope', '$filter', function($rootScope, $filter)

(The array is only needed when you use minification in your build process)

To call specific filter programmatically:

$filter('date')(new Date(), 'yyyy-MM-01');

$filter(name)returns the specific filter function, which you can than call with your arguments:

var dateFilter = $filter('date');
var filteredDate = dateFilter(new Date(), 'yyyy-MM-01')
