Usage

Define your resource

  property id : Int32?
  property name : String
  property description : String?
  property other_resource : OtherResource?
  property dependencies : Array(Dependency) = [] of Dependency
  property brother_id : Int32?

  def initialize(@name)
  end
end

Define your serializer

class MyResourceSerializer < JSONApiSerializer::ResourceSerializer(MyResource)
  identifier id
  type "my-resource"
  attribute name
  attribute description
  relationship(other_resource) { @other_resource_serializer }
  relationship(dependencies) { DependencyResourceSerializer.new }
  relationship_id brother_id, "brother", "brothers"

  def initialize(@other_resource_serializer : OtherResourceSerializer)
    super(nil)
  end
end

Start serializing and deserializing

require "jsonapi-serializer-cr"

# instantialize serializer (MyResourceSerializer) and entity (MyResource)
# ...

# serialize
json = serializer.serialize(entity)

# or deserialize
entity = serializer.deserialize(json)

# You can set options to the serializer
serializer.options = JSONApiSerializer::SerializeOptions.new(change_case: "camelcase")

# You can deserialize a object replacing the attributes based on an already constructed object (updating an existing object)
entity = serializer.deserialize! json, my_resource

# The difference between "deserialize!" and "deserialize" is that "deserialize!" throws JSONApiSerializer::DeserializeException, "deserialize" only return nil
