EmberCli::Deploy::Redis

EmberCLI Rails is a tool to unify your EmberCLI and Rails Workflows.

ember-cli-deploy is a simple, flexible deployment for your Ember CLI app.

ember-cli-deploy-redis is an ember-cli-deploy plugin to upload index.html to a Redis store.

ember-cli-rails-deploy-redis is a gem that integrates all three.

This project streamlines the process of pushing and serving EmberCLI-built assets from Rails.

Install

Add this line to your application's Gemfile:

gem "ember-cli-rails-deploy-redis"

And then execute:

$ bundle install

Setup

First, configure your application to integrate with ember-cli-rails.

Then, to integrate with ember-cli-deploy's "Lightning Fast Deploys" (using the Redis adapter) in production, configure EmberCLI-Rails to deploy with the EmberCli::Deploy::Redis strategy:

# config/initializers/ember.rb

EmberCli.configure do |config|
  config.app :frontend, deploy: { production: EmberCli::Deploy::Redis }
end

Finally, set ENV["REDIS_URL"] to the URL ember-cli-deploy-redis references.

If you're deploying from Redis in development or test, disable EmberCLI-Rails' build step by setting ENV["SKIP_EMBER"] = true.

Deploy

Deploy your application through ember-cli-deploy-redis.

ember-cli-rails will render the index.html retrieved from Redis in the same way it renders the index.html generated by ember build.

Without ember-cli-rails

Although this gem was designed to integrate with ember-cli-rails, there isn't a direct dependency on it.

Similar behavior can be achieved by using a gem like html_page:

require "html_page"

class EmberHelper
  def render_html(html)
    capturer = HtmlPage::Capture.new(self, &block)

    head, body = capturer.capture

    renderer = HtmlPage::Renderer.new(
      content: html,
      head: head,
      body: body,
    )

    render inline: renderer.render
  end
end

class EmberController
  def index
    redis = EmberCli::Deploy::Redis.new(ember_app)

    @html_from_redis = redis.index_html

    render layout: false
  end

  private

  def ember_app
    OpenStruct.new(name: "my-ember-app")
  end
end
<!-- app/views/ember/index.html.erb -->
<%= render_html @html_from_redis do |head, body| %>
  <% head.append do %>
    <title>Appended to the `head` element</title>
  <% end %>

  <% body.append do %>
    <p>Appended to the `body` element</p>
  <% end %>
<% end %>

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake rspec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
