Graphene

Graphene is a Python library for building GraphQL schemas/types fast and easily.

Easy to use: Graphene helps you use GraphQL in Python without effort.
Relay: Graphene has builtin support for Relay
Data agnostic: Graphene supports any kind of data source: SQL (Django, SQLAlchemy), NoSQL, custom Python objects, etc. We believe that by providing a complete API you could plug Graphene anywhere your data lives and make your data available through GraphQL.

Integrations

Graphene has multiple integrations with different frameworks:

integration	Package
Django	graphene-django
SQLAlchemy	graphene-sqlalchemy
Google App Engine	graphene-gae
Peewee	In progress (Tracking Issue)

Installation

For instaling graphene, just run this command in your shell

pip install "graphene>=1.0"

1.0 Upgrade Guide

Please read UPGRADE-v1.0.md to learn how to upgrade.

Examples

Here is one example for you to get started:

class Query(graphene.ObjectType):
    hello = graphene.String(description='A typical hello world')

    def resolve_hello(self, args, context, info):
        return 'World'

schema = graphene.Schema(query=Query)

Then Querying graphene.Schema is as simple as:

query = '''
    query SayHello {
      hello
    }
'''
result = schema.execute(query)
