EasyCdn

This is a gem for easy cdn support of any library whatsoever for Ruby on Rails It generates link or script tags for the specified files.

Installation

Add this line to your application's Gemfile:

gem 'easy_cdn', :git => 'git://github.com/insignificantMe/easy_cdn.git'

And then execute:

$ bundle

Or install it yourself as:

$ gem install easy_cdn

Usage

First specify which files you want to be 'cdn'-ed like this:

Rails.application.config.assets.easy_cdn_config = [
  {
    lib: 'jquery',
    local_dir: 'the/subdirectory/of/the/local/library', #this field is optional
    ext: 'js',
    cdn: "//ajax.googleapis.com/ajax/libs/jquery/#{JQUERY_VERSION}/", # optional
  },
]

Where JQUERY_VERSION should be a variable holding your version of the library This configuration usually sits in config/initializers/easy_cdn.rb but the name of the file is not important

The :cdn property is optional to allow the resources to be loaded in the correct order, no matter whether they are on a cdn or on the application server.

Then just add

 <%= easy_cdn 'filetype', options_hash %>

Wherever you want the link or script tags included

The filetype argument could be:

  1. 'all' - this is by default
  2. 'js'
  3. 'css'

The options_hash argument would be used for creating tag attributes for the generated tags e.g

<%= easy_cdn 'css', 'data-turbolinks-track' => true %>

would generate

<link href="the-link-configured-for-a-css-file" data-turbolinks-track="true">

Trivia

This gem was created because while developing http://yetanotherprettifier.com/ I found only tailored cdn gems and not a single generic one. I hope it would be useful.
