require 'faraday_middleware'

## in Faraday 0.8 or above:
connection = Faraday.new 'http://example.com/api' do |conn|
  conn.request :oauth2, 'TOKEN'
  conn.request :json

  conn.response :xml,  :content_type => /\bxml$/
  conn.response :json, :content_type => /\bjson$/

  conn.use :instrumentation
  conn.adapter Faraday.default_adapter

## with Faraday 0.7:
connection = Faraday.new 'http://example.com/api' do |builder|
  builder.use FaradayMiddleware::OAuth2, 'TOKEN'
  builder.use FaradayMiddleware::EncodeJson

  builder.use FaradayMiddleware::ParseXml,  :content_type => /\bxml$/
  builder.use FaradayMiddleware::ParseJson, :content_type => /\bjson$/

  builder.use FaradayMiddleware::Instrumentation
  builder.adapter Faraday.default_adapter
