Conventions for setting up a GraphQL Server on Rails - List users

query_type.rb

# app/graphql/types/query_type.rb
module Types
  class QueryType < Types::BaseObject
    field :users, [Types::UserType], null: false

    def users
      resolver = UsersResolver.new(context)
      resolver.users
    end
  end
end

# app/graphql/types/user_type.rb
module Types
  class UserType < Types::BaseObject
    field :id, ID, null: false
    field :name, String, null: false
    field :avatar_path, String, null: false
    
    def avatar_path
      # This won't cause an N+1 - see resolver below.
      Rails.application.routes.url_helpers.rails_blob_path(user.avatar, only_path: true)
    end
  end
end
