Graphene Logo Graphene Build Status PyPI version Coverage Status

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)

Also, Graphene is fully compatible with the GraphQL spec, working seamlessly with all GraphQL clients, such as Relay, Apollo and gql.

Installation

For instaling graphene, just run this command in your shell

pip install "graphene>=2.0"

2.0 Upgrade Guide

Please read UPGRADE-v2.0.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, info):
        return 'World'

schema = graphene.Schema(query=Query)

Then Querying graphene.Schema is as simple as:

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