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… We believe that by providing a complete API you could plug Graphene anywhere your data lives and make your data available through GraphQL.

1.0 Upgrade Guide

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

Examples

Here is one example for get you 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)
