Bring ActionCable support to Opal.

Add this line to your application's Gemfile:

gem 'opal-actioncable'

And then execute:

$ bundle

Or install it yourself as:

$ gem install opal-actioncable

# assets/javascript/application.rb
require 'opal-actioncable'

class TestChannel < ActionCable::Subscription
  def connected
    perform 'send', {data: 23}
  end

  def disconnected
  end

  def received data
  end
end

consumer = ActionCable.createConsumer
consumer.subscriptions.create TestChannel

# or

ChatChannel =  TestChannel
consumer.subscriptions.create ChatChannel, {channel: 'Chat', room: 'default'}

If you send your messages in the format {action: ..., data: ...}

ActionCable.server.broadcast "channel", {action: 'action_name', data: {some: 'data'}}

And if action and data are the only keys in your hash, you can catch it on client side like this:

class TestChannel < ActionCable::Subscription
  def action_name params
    puts params # > {some: 'data'}
  end
end

After checking out the repo, run bin/setup to install dependencies. Then, 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 to create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
