|
|
|
|
`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
|
|
- **Django:** Automatic *Django model* mapping to Graphene Types. Check
|
|
a fully working
|
|
`Django <http://github.com/graphql-python/swapi-graphene>`__
|
|
implementation
|
|
|
|
Graphene also supports *SQLAlchemy*!
|
|
|
|
*What is supported in this Python version?* **Everything**: Interfaces,
|
|
ObjectTypes, Scalars, Unions and Relay (Nodes, Connections), in addition
|
|
to queries, mutations and subscriptions.
|
|
|
|
**NEW**!: `Try graphene
|
|
online <http://graphene-python.org/playground/>`__
|
|
|
|
Installation
|
|
------------
|
|
|
|
For instaling graphene, just run this command in your shell
|
|
|
|
.. code:: bash
|
|
|
|
pip install graphene
|
|
# In case of need Django model support
|
|
pip install graphene[django]
|
|
# Or in case of need SQLAlchemy support
|
|
pip install graphene[sqlalchemy]
|
|
|
|
Examples
|
|
--------
|
|
|
|
Here is one example for get you started:
|
|
|
|
.. code:: python
|
|
|
|
class Query(graphene.ObjectType):
|
|
hello = graphene.String(description='A typical hello world')
|
|
ping = graphene.String(description='Ping someone',
|
|
to=graphene.String())
|
|
|
|
def resolve_hello(self, args, info):
|
|
return 'World'
|
|
|
|
def resolve_ping(self, args, info):
|
|
return 'Pinging {}'.format(args.get('to'))
|
|
|
|
schema = graphene.Schema(query=Query)
|
|
|
|
Then Querying ``graphene.Schema`` is as simple as:
|
|
|
|
.. code:: python
|
|
|
|
query = '''
|
|
query SayHello {
|
|
hello
|
|
ping(to:"peter")
|
|
}
|
|
'''
|
|
result = schema.execute(query)
|
|
|
