Sprockets::Traceur

Introductory blog post

This gem integrates traceur-rb with Sprockets (and through Sprockets, with Rails Asset Pipeline).

Installation

Add this line to your application's Gemfile:

gem 'sprockets-traceur'

And then execute:

$ bundle

Or install it yourself as:

$ gem install sprockets-traceur

Usage with Rails

1. Add sprockets-traceur to your Gemfile.

2. Add the following line in app/assets/javascripts/application.js:

   //= require traceur-runtime
   

3. Add .js.es6 or .js.next extension to the files you wish to have transpiled.

4. Profit!

Usage with Sinatra/Rack

1. Add sprockets-traceur to your Gemfile.

2. Configure Rack to use Sprockets (in config.ru):

   require "my_rack_application"
   
   map "/assets" do
     root = File.dirname(__FILE__)
     environment = Sprockets::Environment.new
     environment.append_path root + '/assets/javascripts'
     environment.append_path root + '/assets/stylesheets'
     run environment
   end
   
   map "/" do
     run MyRackApplication
   end
   

3. Add .js.es6 or .js.next extension to the files you wish to have transipled.

4. Add the following line in assets/javascripts/application.js:

   //= require traceur-runtime
   

5. Reference the JS files in your views

   <!-- /assets/application.js 
        maps to /assets/javascripts/application.js[.next|.es6] -->
   <script type="text/javascript" src="/assets/application.js"></script>
   

6. Profit!
