angular-relative-date

AngularJS filter for creating relative, human-readable dates.

A vanilla JavaScript (i.e. not Angular) version of this module is available: wildlyinaccurate/tiny-relative-date

Usage

For regular usage, just download and include dist/angular-relative-date.js in your application.

<script src="angular-relative-date.js"></script>

You can also use the ES6 module directly using a packaging tool like browserify or webpack.

import relativeDate from 'angular-relative-date'

Add the relativeDate module to your application's dependencies.

angular.module('myApp', ['relativeDate']);

Use the filter by passing it date strings or Date objects.

<script>
angular.module('myApp', ['relativeDate']).controller('MainCtrl', function($scope) {
    $scope.dateString = '2015-05-08';
    $scope.dateObject = new Date();
});
</script> 
 
<p>Date strings work: <strong>{{ dateString | relativeDate }}</strong></p>
<p>And so do <code>Date</code> objects: <strong>{{ dateObject | relativeDate }}</strong></p>

The above example will look something like this:

Date strings work: a week ago

And so do Date objects: just now

i18n

Simple internationalisation support is available via the relativeDateTranslations value. See below for all available translation keys.

<script>
angular.module('myApp', ['relativeDate'])
       .value('relativeDateTranslations', {
            just_now: '今'
       })
       .controller('MainCtrl', function($scope) {
            $scope.lastUpdated = new Date();
        });
</script> 
 
<p>Last updated: <strong>{{ lastUpdated | relativeDate }}</strong></p>

The above will output:

Last updated: 今

As well as the built-in translation, angular-translate is also supported. Simply add the translation keys to your $translateProvider.

myApp.config(function ($translateProvider) {
    $translateProvider.translations('en', {
        just_now: 'just now',
        seconds_ago: '{{time}} seconds ago',
    });
 
    $translateProvider.translations('de', {
        just_now: 'soeben',
        seconds_ago: 'vor {{time}} stunden',
    });
 
    $translateProvider.preferredLanguage('en');
});
