Inject dateFilter in a service in AngularJs

I would like to know if there is a way to inject the filters in a service in AngularJs.

I've been trying

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

// ..... Some code

// What I want
console.log(dateFilter(new Date(), 'yyyy-MM-01'));

// ..... Some code


So I would like to know if it is possible to inject a filter in a service or maybe it is accessible in another way.

And if you have a link to a documentation about this point, it would be really nice :) Been searching in the doc of Angular and I found nothing really helpful about this.

Thanks :)

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')
