Add this line to your application's Gemfile:

gem 'json-compare'

And then execute:

$ bundle

Or install it yourself as:

$ gem install json-compare


require 'yajl'
require 'json-compare'

json1 ='spec/fixtures/twitter-search.json', 'r')
json2 ='spec/fixtures/twitter-search2.json', 'r')
old, new = Yajl::Parser.parse(json1), Yajl::Parser.parse(json2)
result = JsonCompare.get_diff(old, new)

If you want to exclude some keys from comparison use exclusion param:

exclusion = ["from_user", "to_user_id"]
result = JsonCompare.get_diff(old, new, exclusion)
