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
endThis 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.
TODO
- Nicer
- Documentation
- Tests
- Make more generic for alternate server implementations?
Thanks
The latest WebSocket draft support is adapted from https://github.com/gimite/web-socket-ruby -- thank you!
