moment.js template helpers for Ember.js
ember install ember-moment
Compatibility:
Ember Classic : < v9 // the ember-classic branch.
the ember-classic branch is in maintenance mode, and will only receive bugfixes
Ember Octane+ : >= v9 // the default branch
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.
{{moment <date>}}
| Parameters | Values |
|---|---|
<date> | Any value(s) interpretable as a date/time by moment (a date String or a Moment or a Date...) |
Returns a Moment.
Example
{{moment '12-25-1995' 'MM-DD-YYYY'}} {{!-- Mon Dec 25 1995 00:00:00 GMT-0500 --}}
{{utc <date>}}
{{utc}}
| Parameters | Values |
|---|---|
<date> | Any value(s) interpretable as a date/time by moment (a date String or a Moment or a Date...) |
Returns a Moment with utc mode set.
Example
{{utc '2001-10-31T08:24:56'}} {{!-- Wed Oct 31 2001 08:24:56 GMT+0000 --}}
{{utc}} {{!-- current time utc, like Mon Feb 12 2018 20:33:08 GMT+0000 --}}
{{utc (moment '2018-01-01T00:00:00+01:00' 'YYYY-MM-DD HH:mm:ssZ')}} {{!-- Sun Dec 31 2017 23:00:00 GMT+0000 --}}
{{moment-format <date> [outputFormat=moment.defaultFormat [<inputFormat>]]}}
| Parameters | Values |
|---|---|
<date> | Any value(s) interpretable as a date/time by moment (a date String or a Moment or a Date...) |
outputFormat | An optional date/time String output format, defaults to moment.defaultFormat which you must explicitly define |
<inputFormat> | An optional date/time String input format |
Formats a <date> to an optional outputFormat from an optional inputFormat. If the inputFormat is not provided, the date String is parsed on a best effort basis. If the outputFormat is not given the global moment.defaultFormat is used. Typically, outputFormat and inputFormat are given. See momentjs#format.
NOTE: for all other helpers, the input format string is the second argument.
Example
{{moment-format '12-1995-25' 'MM/DD/YYYY' 'MM-YYYY-DD'}} {{!-- 12/25/1995 --}}
{{moment-from <dateA> [<dateB>] [hideAffix=false]}}

| Parameters | Values |
|---|---|
<dateA> | Any value(s) interpretable as a date/time by moment (a date String or a Moment or a Date...) |
<dateB> | An optional value(s) interpretable as a date/time by moment (a date String or a Moment or a Date...), defaults to now |
hideAffix | An optional Boolean to hide the relative prefix/suffix or not. |
Returns the time between <dateA> and <dateB> relative to <dateB>. See momentjs#from.
Note that moment-from-now is just a more verbose moment-from without dateB. You don't need to use it anymore.

{{!-- interval is a common named parameter (see the corresponding section) }}
{{now interval=1000}} {{!-- <current date and updating every 1-second (1000 milliseconds).> --}}
{{unix <timestamp>}}
| Parameters | Values |
|---|---|
<timestamp> | An integer Number or String value representing the number of seconds since the Unix Epoch (January 1 1970 12AM UTC) |
Returns a Moment corresponding to the <timestamp>.

{{!-- Warning: Passing a literal integer value does not work --}}
{{unix 1516586508}} {{!-- Invalid date --}}
All helpers accept the following optional named arguments (even though they are not always applicable):
| Parameters | Values |
|---|---|
locale | An optional String locale, to override the default global moment.locale |
timeZone | An optional String time zone, defaults to moment.timeZone (the default time zone) |
interval | An optional interval Number of milliseconds when the helper should be recomputed |
allow-empty | An optional Boolean to ignore the Invalid date output when knowingly passing null, undefined, or '', defaults to false |
Note that interval does not recompute the value of the helper parameters, unless it is
part of a helper that is a value in which case it is useful for "live" updating as time elapses.
Warning: allow-empty is currently inconsistent and should not always be trusted.
Examples
{{now interval=1000}} {{!-- <current date and updating every 1-second (1000 milliseconds)> --}}
{{is-before (now) '2018-01-26' interval=60000}} {{!-- if this was true initially, it will always be true despite interval --}}
{{moment-format '' allow-empty=true}} {{!-- <nothing> --}}
This addon provides the ability to import moment as an ES6 module.
import moment from 'moment';
You can optionally include the Moment Timezone package in your config/environment.js like so:
// config/environment.js
module.exports = function() {
return {
moment: {
// Options:
// 'all' - all years, all timezones
// 'subset' - 2012-2022, all timezones
// 'none' - no data, just timezone API
includeTimezone: 'all'
}
}
};
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.
// config/environment.js
module.exports = function() {
return {
moment: {
outputFormat: 'L'
}
}
};
If you need to change the default format during runtime, use the service API. Doing so will cause the moment-format helper instances to re-render with the new default format.
// app/controller/index.js
export default Ember.Controller.extend({
moment: Ember.inject.service(),
actions: {
changeDefaultFormat() {
this.set('moment.defaultFormat', 'MM.DD.YYYY');
}
}
})
If null, undefined, or an empty string are passed as a date to any of the moment helpers then you will get 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.
// config/environment.js
module.exports = function() {
return {
moment: {
allowEmpty: true // default: false
}
}
};
// config/environment.js
module.exports = function(environment) {
return {
moment: {
// To cherry-pick specific locale support into your application.
// Full list of locales: https://github.com/moment/moment/tree/2.10.3/locale
includeLocales: ['es', 'fr-ca']
}
};
// config/environment.js
module.exports = function(environment) {
return {
moment: {
includeLocales: true
}
};
NOTE: English is bundled automatically, no need to add en in includeLocales
distAlternatively, you can copy all of moment's locale files into your dist directory.
// config.environment.js
module.exports = function(environment) {
return {
moment: {
// This will output _all_ locale scripts to assets/moment-locales
// this option does not respect includeLocales
localeOutputPath: 'assets/moment-locales'
}
};
This allows you to load them on demand when you need them:
Ember.$.getScript('/assets/moment-locales/fr.js');
// app/routes/applicaton.js
export default Ember.Route.extend({
moment: Ember.inject.service(),
beforeModel() {
this.get('moment').setLocale('es');
}
});
// app/routes/applicaton.js
export default Ember.Route.extend({
moment: Ember.inject.service(),
beforeModel() {
this.get('moment').setTimeZone('America/Los_Angeles');
}
});
Invalid Dateis 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.
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 ''}} {{!-- Invalid date --}}
{{moment-format '' allow-empty=true}} {{!-- <nothing> --}}
