CloudfrontInclude

This gem hooks into ActionView::Helpers::AssetTagHelper and provides some asset tags that will replace a local resource with something hosted on a CDN, like Amazon's CloudFront. This is an easy way to use a CDN in your code with only minor effort on your part. Your users will see greatly reduced load time and you'll see happier users.

Installation

Add this line to your application's Gemfile:

gem 'cloud_front_helpers'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cloud_front_helpers

Setup

Set up an initializer at

./config/initializers/cloud_front_helpers.rb

This initializer should look something like:

AssetTagHelper.configure do |config|
  config.cloud_front_url = "https://YOUR_CDN_URL.cloudfront.net" if Rails.env.production?
end

If no initializer exists, your code will still work but it'll just run like normal (off your asset pipeline).

Usage

Once you've set up your initializer, including CDN assets has never been simpler. We've included helpers for image, styles, and scripts.

<%= cf_image_tag "/images/foo.png" %>
<%= cf_javascript_include_tag "/javascripts/spaceCats.js" %>
<%= cf_stylesheet_link_tag "/stylesheets/bar.css" %>

In addition to these asset tag helpers, we've included a sass extension for your background and background-image tags. In any stylesheet, put something like this: 

.whatever {
  background: cf_url("/path/to/some/image.jpg");
}

And that's it!
