Exposing an API

APIs are becoming an essential feature of modern web applications. Rails does a good job of helping your application provide an API using the same MVC structure you're accustomed to.

In the Controller

Let's work with the following example controller:

class ArticlesController < ApplicationController

#
# A basic, synthetic benchmark of the impact HTTP client has
# on the speed of talking to ElasticSearch in the Tire gem.
#
# In general, Curb seems to be more then two times faster the RestClient, in some cases it's three
# to five times faster. I wonder if keep-alive has anything to do with it, but it probably does.
#
# Run me with:
#     $ git clone git://github.com/karmi/tire.git
#     $ cd tire

data = ["1", "11", "111", "2", "22", "222", "3", "4", "5"]
y = (1..9).inject({}) { |memo, data| memo[data.to_s] = 0; memo }
data.each { |z| y[z.chr] = y.fetch(z.chr, 0) + 1 }
puts y

y = {};(1..9).map { |x| y[x.to_s] = 0 }
data.each { |z| y[z.chr] = y.fetch(z.chr, 0) + 1 }
puts y
