  • CRUD Is Not REST - Hypermedia For Y'All!

    by Nick Sutterer

    REST is an architectural style for distributed systems. However, manyimplementations forget about the distributed part of REST and simplymap CRUD operations to HTTP verbs in a monolithic application. We're gonna go further and learn why hypermedia is the crucial part of REST architectures and how machines can browse resources just like humans using self-describing representations.

    Monolithic applications are boring, so let's separate things andcreate a REST system as it is intended to be. Let's build a simplesystem using the Roar gem, Rails and Sinatra and discuss the benefits and drawbacks we get from distributed hypermedia systems.

  • Resources, For Real This Time (with Webmachine)

    by Sean Cribbs

    Over the past 5-6 years we have seen a lot of changes in the way that Ruby apps speak HTTP -- from Rails' "REST" conventions, to the brilliantly simple Sinatra, to the modular Rack abstraction -- but we haven't yet unlocked the entire subtle power of HTTP. We know HTTP is so much more than verbs and URLs that correspond to CRUD, and yet it's still too hard to do conditional requests, content negotiation, and then return the right type of response.

    What if, instead of forcing HTTP into our MVC-shaped applications, we shaped our applications like HTTP? Instead of forcing a resource into seven controller actions or verb/URL-specific methods, what if the resource itself was the abstraction? A whole world of subtle and powerful programming patterns emerge.

    This is the world of Webmachine, a toolkit for building HTTP applications and a port of the Erlang toolkit of the same name. I will introduce Webmachine's unique programming model and demonstrate how to easily expose rich HTTP behavior in a few short lines of code.
