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

About

This gem is ruby wrapper for optimize-js. It allows you to invoke optimize-js from ruby. For Rails users this gem automatically integrates optimize-js into sprockets.

Installing gem

If you are using bundler.
Add to your Gemfile:

gem 'optimize-js', '~> 1.0'

If you are not using bundler.
Run in your terminal:

gem install optimize-js

Require gem in your ruby sources:

require 'optimize-js'

Using gem

API is quite simple.

# OptimizeJS.perform(javascript_source, optimize_js_options)

OptimizeJS.perform('!function() {}()') # => !(function() {})()

Using in Rails

There is no need to do anything.
Gem will automatically register OptimizeJS::SprocketsProcessor using register_bundle_processor so all your JavaScript assets will be optimized.
