Please read `UPGRADE-v2.0.md </UPGRADE-v2.0.md>`__ to learn how to
upgrade to Graphene ``2.0``.

=========================================================================================================
`Graphene <http://graphene-python.org>`__ 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 <https://github.com/graphql-python/graphene-django/>`__ |
+---------------------+----------------------------------------------------------------------------------------------+
| SQLAlchemy | `graphene-sqlalchemy <https://github.com/graphql-python/graphene-sqlalchemy/>`__ |
+---------------------+----------------------------------------------------------------------------------------------+
| Google App Engine | `graphene-gae <https://github.com/graphql-python/graphene-gae/>`__ |
+---------------------+----------------------------------------------------------------------------------------------+
| Peewee | *In progress* (`Tracking Issue <https://github.com/graphql-python/graphene/issues/289>`__) |
+---------------------+----------------------------------------------------------------------------------------------+
Also, Graphene is fully compatible with the GraphQL spec, working
seamlessly with all GraphQL clients, such as
`Relay <https://github.com/facebook/relay>`__,
`Apollo <https://github.com/apollographql/apollo-client>`__ and
`gql <https://github.com/graphql-python/gql>`__.
Installation
------------
For instaling graphene, just run this command in your shell
.. code:: bash
pip install "graphene>=2.0"
2.0 Upgrade Guide
-----------------
Please read `UPGRADE-v2.0.md </UPGRADE-v2.0.md>`__ to learn how to
upgrade.
Examples
--------
Here is one example for you to get started:
.. code:: python
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:
.. code:: python
query = '''
query SayHello {
hello
}
'''
result = schema.execute(query)
If you want to learn even more, you can also check the following

- **Relay Schema**: `Starwars Relay
