I experience the same problem. I tried the following code. The block that invokes send_message is executed, but the message is not being sent. What am I probably doing wrong?

require 'eventmachine-tail'
require 'json'

class TailAction < Cramp::Action
  include SocketIo::Websocket

  on_start :subscribe
  on_finish :unsubscribe

  @@channel = EventMachine::Channel.new
  @@filetail = EventMachine::file_tail('/tmp/ponytail') do |filetail, line|
    @@channel.push line
  end

  def subscribe
    @sid = @@channel.subscribe do |m|
      send_message(data: { message: m }.to_json)
    end
  end

  def unsubscribe
    @@channel.unsubscribe(@sid) if @sid
  end
end

  <script type="text/javascript" src="javascripts/socket.io.min.js"></script>
  <script>
    var socket = io.connect('/socket.io');
    socket.on('message', function(message) {
      alert(message);
    });
  </script>

I've abandoned this project for two reasons: 1.) I'm not longer working on the problem this tool attempted to solve, and 2.) Cramp has been superseded by Celluloid/Lattice https://github.com/celluloid/lattice

If I find myself needing a Ruby socket-io implementation, I'd focus on a lattice-based service.

I'll accept pull requests, but I have no plans of maintaining this.

I actually happen to be working on an app right now where this library would be perfect (Socket.IO without dealing with JS!).

I noticed you mentioned Lattice, but as far as I can tell, that is completely unfinished - there is no real code in the lib folder, besides a script that sets a VERSION constant. Am I missing something?

Besides that, do you have any other recommendations on libraries that may be useful for building a WebSocket application?

Thanks in advance!

I decided not to use WebSockets, after all. SSE (with long polling fallback for IE) seemed to me the way to go. Cramp supports both out of box.
