[ANN] rest-core 0.2.0 released


by Cardinal Blue http://cardinalblue.com



A modular Ruby REST client collection/infrastructure.

In this era of web services and mashups, we have seen a blooming of REST APIs. One might wonder, how do we use these APIs easily and elegantly? Since REST is very simple compared to SOAP, it is not hard to build a dedicated client ourselves.

We have developed rest-core with composable middlewares to build a REST client, based on the effort from rest-graph. In the cases of common APIs such as Facebook, Github, and Twitter, developers can simply use the built-in dedicated clients provided by rest-core, or do it yourself for any other REST APIs.


  • Tested with MRI (official ruby) 1.9.2, 1.8.7, and trunk
  • Tested with Rubinius (rbx) 1.2
  • Tested with JRuby 1.6


gem install rest-core

Or if you want development version, put this in Gemfile:

gem 'rest-core', :git => 'git://github.com/cardinalblue/rest-core.git',
                 :submodules => true

Built-in Clients Example:

require 'rest-core'

RestCore::Twitter.new.statuses('godfat') # get user tweets
RestCore::Github.new.get('users/godfat') # get user info

linkedin = RestCore::Linkedin.new(:consumer_key    => '...',
                                  :consumer_secret => '...')
linkedin.authorize_url!   # copy and paste the URL in browser to authorize
linkedin.authorize!('..') # paste your code from browser
linkedin.me               # get current user info

# below is exactly the same as [rest-graph][]
require 'rest-core/client/rest-graph'
RestGraph.new.get('4')                   # get user info

See example for more complex examples.

Build Your Own Clients Example:

require 'rest-core'

YourClient = RestCore::Builder.client do
  use DefaultSite , 'https://api.github.com/users/'
  use JsonDecode  , true
  use CommonLogger, method(:puts)
  use Cache       , {}, 3600
  run RestClient

client = YourClient.new
client.get('godfat') # cache miss
client.get('godfat') # cache hit

client.site = 'http://github.com/api/v2/json/user/show/'
client.get('godfat') # cache miss
client.get('godfat') # cache hit

See built-in clients for more complex examples.
