=========================================================================================================
|
|
|
|
`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:

|
|
|
|
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)
|
|
|
