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
