Ruby objects and JSON serialization (without Rails)

Question

I\'m trying to understand the JSON serialization landscape in Ruby. I\'m new to Ruby.

Is there any good JSON serialization options if you are not working with Rails?

Answer 1

Since I searched a lot myself to serialize a Ruby Object to json:

require 'json'

class User
  attr_accessor :name, :age

  def initialize(name, age)
    @name = name
    @age = age
  end

  def as_json(options={})
    {
      name: @name,
      age: @age
    }
  end

  def to_json(*options)
    as_json(*options).to_json(*options)
  end
end

user = User.new("Foo Bar", 42)
puts user.to_json #=> {"name":"Foo Bar","age":42}
