Quit pretending

CRUD through HTTP is a good step forward to using resources and becoming RESTful, another step further into it is to make use of hypermedia and semantic meaningful media types: this gem allows you to do it really fast.

You can read the article on using the web for real which gives an introduction to hypermedia/resources/services.

Why would I use restfulie?

1. Easy —> writing hypermedia and semantic meaningful media type aware clients
2. Small → it’s not a bloated solution with a huge list of APIs
3. HATEOAS —> clients you are unaware of will not bother if you change
4. HATEOAS —> consumed resources will not affect your software whenever they change their flow
5. Adaptability —> clients are able to adapt to your changes

Simple server example

In the server side, all you need to do is notify inherited_resources which media types you are able to represent your resource:

	class OrdersController < ApplicationController
	  include Restfulie::Server::ActionController::Base

	  respond_to :atom, :html, :xml, :commerce, :opensearch

	  def index
	    respond_with @orders = Order.all
	  end

	  def show
	    respond_with @order = Order.find(params[:id])
	  end

	end

That’s it. Restfulie will take care of rendering a valid representation according to content negotiation. You can configure the rendering process through a custom tokamak view:

	collection(@orders) do |collection|
	  collection.values do |value|
		value.id = orders_url
	  end
	  
	  collection.link("create", orders_url)
	  collection.members
	end

You can go through an entire application by watching this video or "downloading an example application contained within the restfulie ":http://github.com/caelum/restfulie/tree/master/full-examples/rest_from_scratch/

Simple client example

The following example is a partial REST client implementation that navigates through some relations:

order = Restfulie.at('http://localhost:3000/orders/1').get!
order.items.each { |item| puts items }
receipt = order.payment.post! { :amount => 500 }
puts receipt.id

In order to create a full REST client, watch this video.

Full examples

You can view an entire application running Restfulie under spec/integration/order/server and spec/integration/order/client in this git repository.

You can also download a full example of a REST based agent and server using Restfulie, according to the Rest Architecture Maturity Model.

Installing

Execute:

gem install restfulie

For use in Rails 2.3, make sure to require the responders_backport gem in addition to the restfulie gem, either in environment.rb or in the Gemfile.

Building the project

If you want to build the project and run its tests, remember to install all (client and server) required gem.
Bundler is required to easily manage dependencies

bundle install
rake test:spec test:integration
