EmberCLI Rails - Assets

The ember-cli-rails-assets gem extends ember-cli-rails to enable rendering EmberCLI-generated JavaScript and CSS stylesheets into your Rails application's layout HTML.

This project and the behavior it supports is deprecated.

Rendering EmberCLI applications with render_ember_app is the recommended, actively supported method of serving EmberCLI applications.

However, for the sake of backwards compatibility, ember-cli-rails-assets supports injecting the EmberCLI-generated assets into an existing Rails layout.

Install

Add the following to your Gemfile:

gem "ember-cli-rails-assets"

Then run bundle install:

$ bundle install

Setup

To configure your project to use ember-cli-rails, follow the instructions listed in the ember-cli-rails README.

To configure your project to user ember-cli-rails-assets, ensure each Ember application's ember-cli-build.js includes the following values:

// frontend/ember-cli-build.js

module.exports = function(defaults) {
  var app = new EmberApp(defaults, {
    // http://ember-cli.com/user-guide/#application-configuration
    storeConfigInMeta: false,

    fingerprint: {
      // https://github.com/rickharrison/broccoli-asset-rev#options
      generateAssetMap: true,
    },
  });
};

Mount

Mount the Ember application (in this example, the frontend application) to the desired path:

# config/routes.rb

Rails.application.routes.draw do
  mount_ember_app :frontend, to: "/", controller: "ember#index"
end

Then, in the corresponding view, use the asset helpers:

<!-- app/views/ember/index.html.erb -->

<%= include_ember_script_tags :frontend %>
<%= include_ember_stylesheet_tags :frontend %>

Caveats

Mounting

If you're using the include_ember style helpers with a single-page Ember application that defers routing to the Rails application, insert a call to mount_ember_assets at the bottom of your routes file to serve the EmberCLI-generated assets:

# config/routes.rb
Rails.application.routes.draw do
  mount_ember_assets :frontend, to: "/"
end

Rendering

When injecting the EmberCLI-generated assets with the include_ember_script_tags and include_ember_stylesheet_tags helpers to a path other than "/", a <base> tag must also be injected with a corresponding href value:

<base href="/">
<%= include_ember_script_tags :frontend %>
<%= include_ember_stylesheet_tags :frontend %>

<base href="/admin_panel/">
<%= include_ember_script_tags :admin_panel %>
<%= include_ember_stylesheet_tags :admin_panel %>

Rendering without <base> element

To render the asset elements without using a <base> element, pass the URL or path to prepend:

<-- assuming Ember's assets are mounted to `"/"` -->
<%= include_ember_script_tags :frontend, prepend: "/" %>
<%= include_ember_stylesheet_tags :frontend, prepend: "/" %>

<%= include_ember_script_tags :admin_panel, prepend: "/" %>
<%= include_ember_stylesheet_tags :admin_panel, prepend: "/" %>
