Hello; was interested in such approach; was the previous version outdated ? Or should things be done another way ?

Hi, in 1.8+, types can be defined using classes:

class Book < GraphQL::Schema::Object 
  # ... 
end 

So, if you want to dynamically define types, you can use plain old Ruby:

book_type = Class.new(GraphQL::Schema::Object) do 
  graphql_name "Book" 
  # ... 
end
