ember install ember-moment
Upgrading
It's advisable to run ember g ember-moment
between upgrades as dependencies may have been added, removed, or upgraded between releases. Please try this, along with clearing node_modules
and bower_components
before reporting issues after upgrading.

Live Updating of Displayed Time
{{moment-from-now (now) date interval=1000}} // interval is in ms
Recomputes the time ago every 1-second (1000 milliseconds). This is useful for "live" updating as time elapses.
ES6 Moment
This addon provides the ability to import moment as an ES6 module.
import moment from 'moment';
Include Moment Timezone
You can optionally include the Moment Timezone package in your config/environment.js
like so:
module.exports = function() {
return {
moment: {
includeTimezone: 'all'
}
}
};
Configuration Options
Global Default Output Format
Your application may require a default format other than the default, ISO 8601. For example, you may want dates to fallback on the localized shorthand format L
by default.
module.exports = function() {
return {
moment: {
outputFormat: 'L'
}
}
};
If you need to change the default format during runtime, use the service API. During so, will trigger the moment-format helper instances to re-render with the new default format.
export default Ember.Controller.extend({
moment: Ember.inject.service(),
actions: {
changeDefaultFormat() {
this.set('moment.defaultFormat', 'MM.DD.YYYY');
}
}
})
Global Allow Empty Dates
If null
, undefined
, or an empty string as a date to any of the moment helpers then you you will Invalid Date
in the output. To avoid this issue globally, you can set the option allowEmpty
which all of the helpers respect and will result in nothing being rendered instead of Invalid Date
.
module.exports = function() {
return {
moment: {
allowEmpty: true
}
}
};
i18n support
Cherry pick locales (optimal)
module.exports = function(environment) {
return {
moment: {
includeLocales: ['es', 'fr-ca']
}
};
Include all locales into build
module.exports = function(environment) {
return {
moment: {
includeLocales: true
}
};
NOTE: English is bundled automatically, not need to add en
in includeLocales
Write all the locales to a folder relative to dist
Alternatively, you can copy all of moment's locale files into your dist
directory.
module.exports = function(environment) {
return {
moment: {
localeOutputPath: 'assets/moment-locales'
}
};
This allows you to load them on demand when you need them:
Ember.$.getScript('/assets/moment-locales/fr.js');
Configure default runtime locale/timeZone
Globally set locale
export default Ember.Route.extend({
moment: Ember.inject.service(),
beforeModel() {
this.get('moment').changeLocale('es');
}
});
Globally set time zone
export default Ember.Route.extend({
moment: Ember.inject.service(),
beforeModel() {
this.get('moment').changeTimeZone('America/Los_Angeles');
}
});
Inline Localization
All helpers accept a locale
and timeZone
argument, which is a string. This allows for overriding of the global locale.
{{moment-format date locale='es' timeZone='America/Los_Angeles'}}
{{moment-duration (now) date locale='es' timeZone='America/Los_Angeles' timeZone='America/Los_Angeles'}}
{{moment-from-now (now) date locale='es' timeZone='America/Los_Angeles'}}
{{moment-to-now date locale='es' timeZone='America/Los_Angeles'}}

Frequently Asked Questions
Invalid Date
is being rendered into the DOM, how do I avoid this?
An invalid date string is being passed into momentjs and/or the input string format was omitted. For example, if you're using the moment-format
you'll pass the input format as the 3rd argument:
{{moment-format date outputFormat inputFormat}}
NOTE: for all other helpers, the input format string is the second argument.
If you are knowingly passing null, undefined, or an empty string and want to ignore the output of Invalid Date
then pass the option allow-empty=true
to the helper (all helpers accept this property)
{{moment-format date allow-empty=true}}
