Awesome

Skinny

Simple, upgradable Thin WebSockets.

I wanted to be able to upgrade a plain old Rack request to a proper WebSocket. The easiest way seemed to use the oh-so-nice-and-clean Thin with a new pair of skinnies.

More details coming soon.

Examples

More comprehensive examples will be coming soon. Here's a really simple, not-yet-optimised example I'm using at the moment:

class Sinatra::Request
  include Skinny::Helpers
end

module MailCatcher
  class Web < Sinatra::Base
    get '/messages' do
      if request.websocket?
        request.websocket! :protocol => "MailCatcher 0.2 Message Push",
          :on_start => proc do |websocket|
            subscription = MailCatcher::Events::MessageAdded.subscribe { |message| websocket.send_message message.to_json }
            websocket.on_close do |websocket|
              MailCatcher::Events::MessageAdded.unsubscribe subscription
            end
          end
      else
        MailCatcher::Mail.messages.to_json
      end
    end
  end
end

This syntax will probably get cleaned up. I would like to build a nice Sinatra handler with DSL with unbound handlers so Sinatra requests can be recycled.

Make more generic for alternate server implementations?
