Reel is a fast Celluloid::IO-powered web server which supports both
non-blocking and blocking modes of operation:

This release brings three major new features:

WebSockets: Reel now supports WebSockets in addition to standard HTTP
connections. An example of using WebSockets is available here:

celluloid/reel/blob/master/examples/websockets.rb

require 'rubygems'
require 'bundler/setup'
require 'reel'
require 'celluloid/autostart'

class TimeServer
  include Celluloid
  include Celluloid::Notifications

  def initialize
    async.run
  end

  def run
    now = Time.now.to_f
    sleep now.ceil - now + 0.001

    every(1) { publish 'time_change', Time.now }
  end
end

This example shows how to do a message fanout from a single actor to
several websockets connections. This shows how simple it is to use Reel
and
Celluloid to implement WebSockets publish/subscribe systems.

Rack support: Reel now provides a Rack adapter, although the Rack API
severely limits the kinds of end-to-end streaming Reel is capable of
Octarine support: Reel now lets you write simple Sinatra-like
applications using the Octarine gem:

class MyApp
include Reel::App

get ‘/foobar’ { [200, {}, “hello world” }
end

MyApp.new(‘127.0.0.1’, 1234)
