Lets you make a websocket rack application using Celluloid.

With thanks to Tony Arcieri for his awesome Celluloid libraries.

Add this line to your application's Gemfile:

gem 'celluloid-websocket'

And then execute:

$ bundle

Or install it yourself as:

$ gem install celluloid-websocket

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

1. Fork it

3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
