Consuming Rails 5 ActionCable

Question

I\'m playing around with the new ActionCable feature. Is there a way of communicating with the ActionCable server using say socket.io or from an application using React or R

Answer 1

You can interact with ActionCable as you would normally with any WebSocket libraries.

To do so, you would stream from a Channel in Rails:

class ExampleChannel < ApplicationCable::Channel
  def subscribe
    stream_from 'example'
  end
end

Then, you may connect to the Rails WebSocket through your stand-alone client and subscribe to the message using the ActionCable protocol:

function Socket(url) {
  const ws = new WebSocket(url);

  ws.onopen(() => {
    ws.send('{"command":"subscribe","identifier":"{\"channel\":\"ExampleChannel\"}"');
  });
}
