moment.js template helpers and computed property macros for Ember

Requirements

• Ember >= 1.13.0
• Ember CLI

Installing

• ember-cli >= 0.2.3 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.

Usage

Computed Property Macros

Ships with the following computed property macros: duration, humanize, locale, tz, format, calendar, moment, toNow, fromNow. They can be used individually or composed together.

Live Updating of Displayed Time

{{moment-from-now (now 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:

// config/environment.js
module.exports = function() {
  return {
    moment: {
      // Options:
      // 'all' - all years, all timezones
      // '2010-2020' - 2010-2020, all timezones
      // 'none' - no data, just timezone API
      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.

// 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');
    }
  }
})

Global Allow Empty Dates

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
    }
  }
};

i18n support

Cherry pick locales (optimal)

// 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']
    }
  };

Include all locales into build

// config/environment.js
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.

// 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');

Configure default runtime locale/timeZone

Globally set locale

// app/routes/applicaton.js
export default Ember.Route.extend({
  moment: Ember.inject.service(),
  beforeModel() {
    this.get('moment').setLocale('es');
  }
});

Globally set time zone

// app/routes/applicaton.js
export default Ember.Route.extend({
  moment: Ember.inject.service(),
  beforeModel() {
    this.get('moment').setTimeZone('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'}}
{{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}}
