Closure Sprockets

Sprockets preprocessor for Google's Closure tools.

Integrating with Rails 3

If you want to use closure as your Javascript library in Rails 3, add this gem to your Gemfile:

gem 'closure-sprockets'

The gem ships with a Railtie which will automatically register a Closure preprocessor. From here, two more steps:

// in one of your javascript files
goog.require('goog.dom');

newHeader = goog.dom.createDom('h1', {}, 'Hello world!');
goog.dom.appendChild(document.body, newHeader);
}

That's it! Point your browser at your page and you should have a hello world greeting from Google Closure, preprocessed by the Rails 3 Asset Pipeline and without any external Python dependencies or dynamic Javascript loading.

Optional configuration

If you decided to put your closure-library directory somewhere other than vendor/assets, then you'll have to update your environment config with the right path:

config.closure.lib = 'vendor/assets/path/to/closure-library'

Using Closure Compressor for Minification

Closure also provides its own Javascript compressor. If you wish to use it, pull in the closure-compiler gem:

# in your Gemfile
gem 'closure-compiler'
# in your environment configuration
config.assets.js_compressor = Closure::Compiler.new
