Ruby wrapper and Rails asset pipeline integration for optimize-js.

gem 'optimize-js', '~> 1.0'If you are not using bundler.
Run in your terminal:

Require gem in your ruby sources:

API is quite simple.
# OptimizeJS.perform(javascript_source, optimize_js_options)
OptimizeJS.perform('!function() {}()') # => !(function() {})()Using in Rails
