rails--rails/actioncable/CHANGELOG.md

• Add :action_cable_connection and :action_cable_channel load hooks.

  You can use them to extend ActionCable::Connection::Base and ActionCable::Channel::Base functionality:

  ActiveSupport.on_load(:action_cable_channel) do
    # do something in the context of ActionCable::Channel::Base
  end

• Add Channel::Base#broadcast_to.

  You can now call broadcast_to within a channel action, which equals to the self.class.broadcast_to.

  Vladimir Dementyev

• Make Channel::Base.broadcasting_for a public API.

  You can use .broadcasting_for to generate a unique stream identifier within a channel for the specified target (e.g. Active Record model):

  ChatChannel.broadcasting_for(model) # => "chat:<model.to_gid_param>"

Rails 6.0.0.beta1 (January 18, 2019)

• Rename npm package from actioncable to @rails/actioncable.

  Javan Makhmali

• Merge action-cable-testing to Rails.

• The JavaScript WebSocket client will no longer try to reconnect when you call reject_unauthorized_connection on the connection.

  Mick Staugaard

• ActionCable.Connection#getState now references the configurable ActionCable.adapters.WebSocket property rather than the WebSocket global variable, matching the behavior of ActionCable.Connection#open.

  Richard Macklin

• The ActionCable javascript package has been converted from CoffeeScript to ES2015, and we now publish the source code in the npm distribution.

  This allows ActionCable users to depend on the javascript source code rather than the compiled code, which can produce smaller javascript bundles.

  This change includes some breaking changes to optional parts of the ActionCable javascript API:

  • Configuration of the WebSocket adapter and logger adapter have been moved from properties of ActionCable to properties of ActionCable.adapters. If you are currently configuring these adapters you will need to make these changes when upgrading:

    -    ActionCable.WebSocket = MyWebSocket
    +    ActionCable.adapters.WebSocket = MyWebSocket
    

    -    ActionCable.logger = myLogger
    +    ActionCable.adapters.logger = myLogger
    

  • The ActionCable.startDebugging() and ActionCable.stopDebugging() methods have been removed and replaced with the property ActionCable.logger.enabled. If you are currently using these methods you will need to make these changes when upgrading:

    -    ActionCable.startDebugging()
    +    ActionCable.logger.enabled = true
    

    -    ActionCable.stopDebugging()
    +    ActionCable.logger.enabled = false

• Add id option to redis adapter so now you can distinguish ActionCable's redis connections among others. Also, you can set custom id in options.

  Before:

  $ redis-cli client list
  id=669 addr=127.0.0.1:46442 fd=8 name= age=18 ...
  

  After:

  $ redis-cli client list
  id=673 addr=127.0.0.1:46516 fd=8 name=ActionCable-PID-19413 age=2 ...
