jsonapi

Ruby gem for parsing/validating JSON API documents.

Installation

Add the following to your application's Gemfile:

gem 'jsonapi'

And then execute:

$ bundle

Or install it manually as:

$ gem install jsonapi

Usage

First, require the gem.

require 'jsonapi'

Then, parse a JSON API document:

document = JSONAPI.parse(hash_or_json_string)

or an include directive:

include_directive = JSONAPI::IncludeDirective.new(include_args)

Examples

  document = JSONAPI.parse(json_document)
  # Should the document be invalid, the parse method would fail with an
  #   InvalidDocument error.
