Schema

# src/MyBundle/Resources/config/graphql/Query.types.yml
# This is the type that will be the root of our query, and the
# entry point into our schema. It gives us the ability to fetch
# objects by their IDs, as well as to fetch the undisputed hero
# of the Star Wars trilogy, R2-D2, directly.
#
# This implements the following type system shorthand:
#   type Query {
#     hero(episode: Episode): Character
#     human(id: String!): Human
#     droid(id: String!): Droid
#   }
#

            bar:
                query: barQuery
                mutation: barMutation

foo schema endpoint can be access:

type	Path
simple request	/graphql/foo
batch request	/graphql/foo/batch
