introspectionFromSchema
Build an IntrospectionQuery from a GraphQLSchema
IntrospectionQuery is useful for utilities that care about type and field relationships, but do not need to traverse through those relationships.
This is the inverse of buildClientSchema. The primary use case is outside of the server context, for instance when doing schema comparisons.
function introspectionFromSchema(schema: GraphQLSchema, options?: IntrospectionOptions): IntrospectionQuery;
