Opal::Optimizer

A utility to optimize the JavaScript output from Opal with a help of RKelly-Turbo JavaScript parser.

As of now it contains two steps:

• Tree shaking for Opal methods - if a named method is not called anywhere in the code, it's removed
• Collapsing stubs

Add this line to your application's Gemfile:

gem 'opal-optimizer'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install opal-optimizer

For Sprockets environments, all you need is to require "opal/optimizer/sprockets" in your pipeline.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
