Deserialize JSON API formats into vanilla Ruby objects. The simplest JSON API library at all altitudes above Earth centre.

# gem install json-api-vanilla
require "json-api-vanilla"
json = IO.read("articles.json")  # From http://jsonapi.org
doc = JSON::Api::Vanilla.parse(json)
doc.data[0].comments[1].author.last_name  # "Gebhardt"

Compare with jsonapi:

# gem install jsonapi --pre
require "jsonapi"
json = IO.read("articles.json")
doc = JSONAPI.parse(json)
comment_ref = doc.data[0].relationships.comments.data[1]
comment = doc.included.select do |obj|
  obj.type == comment_ref.type && obj.id == comment_ref.id
end[0]
author_ref = comment.relationships.author.data
author = doc.included.select do |obj|
  obj.type == author_ref.type && obj.id == author_ref.id
end[0]
author.attributes['last-name']

JSON::Api::Vanilla.parse(json_string) returns a document with the following fields:

• data is an object corresponding to the JSON API's data object.
• errors is an array containing errors. Each error is a Hash.
• links is a Hash from objects (obtained from data) to their links, as a Hash.
• rel_links is a Hash from objects' relationships (obtained from data) to the links defined in that relationship, as a Hash.
• meta is a Hash from objects to their meta information (a Hash).
• find('type', 'id') returns the object with that type and that id.
• find_all('type') returns an Array of all objects with that type.
• keys is a Hash from objects to a Hash from their original field names (non-snake_case'd) to the corresponding object.
