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.

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.

• Nicer
• Documentation
• Tests
• Make more generic for alternate server implementations?

The latest WebSocket draft support is adapted from https://github.com/gimite/web-socket-ruby -- thank you!
