Compiled EmberJS in Docker

Compiled EmberJS App in Docker

The biggest problem deploying compiled EmberJS apps as a container is the configuration defined during compile time and becomes part of the image. Which is not ideal as you probably want to move the image between QA/UAT and prod without any modification.

The solution I will describe here looks like a hack but it's been working for me.

  1. I put config <meta> tag into index.html:

Quick'n'dirty i18n for Ember application. Allows to switch locales dynamically. Uses `i18n-js` library. Adds handlebars `t` helper and also attribute bindings `placeholderTranslation` to text input views and `promptTranslation` to select view.

Examples:

Literals:

{{t 'user.last_name'}}
{{t 'user.email' count=1}}

Placeholders:

Interesting observation on difference between `array.filterBy` and `Ember.Computed.filterBy`

Apparently array.filterBy creates a new array based on the filtered content, whether Ember.Computed.filterBy reuses the same array.

This difference can be very important when you display a filtered list with {{each}} helper.

For eaxample, if you define the propery like this:

  filteredArray: function(){
    return this.get('content').filterBy('isDone', false);
  }.property('content.@each.isDone')
