Celluloid::WebSocket

Lets you make a websocket rack application using Celluloid.

With thanks to Tony Arcieri for his awesome Celluloid libraries.

Installation

Add this line to your application's Gemfile:

gem 'celluloid-websocket'

And then execute:

$ bundle

Or install it yourself as:

$ gem install celluloid-websocket

Usage

Simply inherit your Rack app from Celluloid::WebSocket::Rack, and implement the on_open method and using the read and write functions to implement a protocol.

require 'celluloid/websocket/rack'

class WebSocketEcho < Celluloid::WebSocket
    def on_open
        @counter = 0
        while(true)
            message = read

            @counter += 1
            write("#{@counter}: #{message}")
        end
    end

    def on_error(*args)
        puts args.inspect
    end
end

run WebSocketEcho.rack

You can try it out by cloning this repository running bundle and then:

passenger start -R examples/message_counter.ru
