Ariadne is a Python library for implementing GraphQL servers.

Ariadne

Ariadne is a Python library for implementing GraphQL servers, inspired by Apollo Server and built with GraphQL-core.

Warning: The work on library is currently in experimental phase. We invite you to give Ariadne a try, but if you are looking to build production-ready GraphQL API, please use more stable solutions such as Graphene.

Quickstart

from ariadne import make_executable_schema
from graphql import graphql

type_defs = """
    type Query {
        people: [Person!]!
    }

    type Person {
        firstName: String
        lastName: String
        age: Int
        fullName: String
    }
"""


def resolve_people(*_):
    return [
        {"firstName": "John", "lastName": "Doe", "age": 21},
        {"firstName": "Bob", "lastName": "Boberson", "age": 24},
    ]


def resolve_person_fullname(person, *_):
    return "%s %s" % (person["firstName"], person["lastName"])


resolvers = {
    "Query": {"people": resolve_people},
    "Person": {"fullName": resolve_person_fullname},

            firstName

result = graphql(schema, query)

assert result.data == {
