Legion::Json is the JSON wrapper that is used by the LegionIO framework. It gives all other gems and extensions a single json library to use for consistency. It wraps multi_json and also json_pure

Additional C extension style json gems can be installed like oj and it they should be used automatically.

Legion::Json should work identically on:

• JRuby 9.2+
• Ruby 2.4+

You can verify your installation using this piece of code:

gem install legion-json

require 'legion-json'
json_string = '{"foo":"bar","nested":{"hello":"world"}}'
Legion::Json.load(json_string)
Legion::Json.load(json_string, symbolize_keys: false) # symbolize_keys defaults to true

hash = {foo: 'bar', nested: {hello: 'world'}}
Legion::Json.dump(hash)
Legion::Json.dump(hash, )
