Ember-moment

moment.js template helpers for ember

Requirements

• HTMLBars (see <= 2.0.0 for Handlebar support)
• Ember >= 1.10
  • If you need support for < Ember 1.10 please use ember-moment 1.x-2.x

Usage

• ember-cli < 0.2.3 ember install:addon ember-moment
• ember-cli >= 0.2.3 ember install ember-moment

{{moment-format date}}
{{moment-from-now date}}
{{moment-to-now date}}
{{moment-duration ms}}

Advance

{{moment-format date outputFormat inputFormat}}
{{moment-from-now date}}
{{moment-to-now date}}
{{moment-duration number units}}

Recomputes the time ago every 1-second. This is useful for "live" updating as time elapses.

NOTE: This feature is only supported in Ember >= 1.13.0

{{moment-from-now date interval=1000}}

Upgrading

If your npm dep for ember-moment is not fixed on a version (ie, using ~ or ^) then you may be required to ember g ember-moment between versions as the default blueprint may have changed.

Please try this, along with clearing node_modules and bower_components before reporting issues after upgrades.

ES6 Moment

This addon provides the ability to import moment as an ES6 module.

import moment from 'moment';

Computed Macro

import momentDuration from 'ember-moment/computeds/duration';
import momentFormat from 'ember-moment/computeds/format';
import momentFromNow from 'ember-moment/computeds/from-now';
import momentToNow from 'ember-moment/computeds/to-now';

export default Ember.Controller.extend({
  date: new Date('2013-02-08T09:30:26'),

  // Takes on the behavior of moment().format()
  // http://momentjs.com/docs/#/displaying/format/
  shortDate: momentFormat('date', 'MM/DD/YYYY'),

  // first param: date input
  // second param: date format http://momentjs.com/docs/#/parsing/string-format/ (optional)
  // third param: hide suffix (optional, false by default)
  // http://momentjs.com/docs/#/displaying/fromnow/
  timeSince: momentFromNow("12-25-1995", "MM-DD-YYYY", false), // -> output: "2 years ago"

  // first param: date input
  // second param: date format http://momentjs.com/docs/#/parsing/string-format/ (optional)
  // third param: hide prefix (optional, false by default)
  // http://momentjs.com/docs/#/displaying/tonow
  computedNumHours: momentToNow("12-25-1995", "MM-DD-YYYY", false), // -> output: "in 20 years"

  // duration units: seconds, minutes, hours, days, weeks, months, years
  // http://momentjs.com/docs/#/durations/
  computedNumHours: momentDuration(10, 'hours')
});

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'
    }
  }
};

Global Default Format

Your application may require a different moment format default other than LLLL. Your application may want dates to be treated in the shorthand date form L by default.

// config.environment.js
module.exports = function() {
  return {
    moment: {
      outputFormat: 'L'
    }
  }
};

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
    }
  };

Configure default runtime locale

Globally

// app/routes/applicaton.js
import moment from 'moment';

export default Ember.Route.extend({
  beforeModel() {
    // sets the application locale to Spanish
    moment.locale('es');
  }
});

Locally

All helpers except a locale argument, which is a string. This allows for overriding of the global locale.

{{moment-format date locale='es'}}
{{moment-duration date locale='es'}}
{{moment-from-now date locale='es'}}
{{moment-to-now date locale='es'}}

Feature set of i18n support within moment can be found here: http://momentjs.com/docs/#/i18n/

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}}
