Conventions for setting up a GraphQL Server on Rails - Schema & QueryType

schema_and_query_type.rb

# app/graphql/my_rails_app_schema.rb
class MyRailsAppSchema < GraphQL::Schema
  mutation(Types::MutationType)
  query(Types::QueryType)
end

# app/graphql/types/query_type.rb
module Types
  class QueryType < Types::BaseObject
    # Add root-level fields here. They will be entry points for queries on your schema.
    field :test_field, String, null: false, description: "An example field added by the generator"
    
    # A method with the same name as the field will be called when that field is asked for in a query.
    def test_field
      "Hello World!"
    end
  end
end
