1. WEBMACHINE THE HTTP TOOLKIT IN RUBY @pawelpacana

2. I’m not a native speaker DISCLAIMER

3. HTTP 1.1 SPEC RFC2616

4. TOOLKIT • „A toolkit for easily creating well- behaved HTTP

   applications” • not a framework • Sinatra vs. Rails • extracted from Riak

5. RACK INTERFACE app = proc { |env| [ 200, #

   Status {'Content-Type' => 'text/plain'}, # Headers ["Hello World!"] # Body ] }

6. RACK MIDDLEWARE • Head, ContentLength, ContentType, Deflater, …

7. HTTP IS HARD

8. WEBMACHINE • FSM modelling HTTP • negotiate hard decisions transparently

9. HTTP IS RESOURCES • data or service • identified by

   URI • representations

10. WEBMACHINE • resources as a core building block • declare

    resources, don’t perform actions • resource callbacks

11. EXAMPLES show me the code

12. ADAPTERS • WEBrick • Mongrel • Rack* • Reel •

    Hatetepe

13. ECOSYSTEM • webmachine-test • webmachine-linking • webmachine-actionview • webmachine-sprockets •

    irwebmachine

14. MY OBSERVATIONS • good as HTTP content delivery mechanism in

    Ports and Adapters architecture • good for Hypermedia APIs • small enough to read and trust it
