Schema Definition

A Schema is created by supplying the root types of each type of operation, query and mutation (optional). A schema definition is then supplied to the validator and executor.

Example:

const MyAppSchema = new GraphQLSchema({
  query: MyAppQueryRootType,
  mutation: MyAppMutationRootType,
})

Note: When the schema is constructed, by default only the types that are reachable by traversing the root types are included, other types must be explicitly referenced.

Example:

const characterInterface = new GraphQLInterfaceType({
  name: 'Character',
  ...
});

const humanType = new GraphQLObjectType({
  name: 'Human',
  interfaces: [characterInterface],
  ...
});

const droidType = new GraphQLObjectType({
  name: 'Droid',
  interfaces: [characterInterface],
  ...
});

const schema = new GraphQLSchema({
  query: new GraphQLObjectType({
    name: 'Query',
    fields: {
      hero: { type: characterInterface, ... },
    }
  }),
  ...
  // Since this schema references only the `Character` interface it's
  // necessary to explicitly list the types that implement it if
  // you want them to be included in the final schema.
  types: [humanType, droidType],
})

Note: If an array of directives are provided to GraphQLSchema, that will be the exact list of directives represented and allowed. If directives is not provided then a default set of the specified directives (e.g. @include and
