Subscriptions
|
|||
|
|
=============
|
|||
|
|
|
|||
|
|
The ``graphene-django`` project does not currently support GraphQL subscriptions out of the box. However, there are
|
|||
|
|
several community-driven modules for adding subscription support, and the provided GraphiQL interface supports
|
|||
|
|
running subscription operations over a websocket.
|
|||
|
|
|
|||
|
|
To implement websocket-based support for GraphQL subscriptions, you’ll need to do the following:
|
|||
|
|
|
|||
|
|
1. Install and configure `django-channels <https://channels.readthedocs.io/en/latest/installation.html>`_.
|
|||
|
|
2. Install and configure* a third-party module for adding subscription support over websockets. A few options include:
|
|||
|
|
|
|||
|
|
- `graphql-python/graphql-ws <https://github.com/graphql-python/graphql-ws>`_
|
|||
|
|
- `datavance/django-channels-graphql-ws <https://github.com/datadvance/DjangoChannelsGraphqlWs>`_
|
|||
|
|
- `jaydenwindle/graphene-subscriptions <https://github.com/jaydenwindle/graphene-subscriptions>`_
|
|||
|
|
|
|||
|
|
3. Ensure that your application (or at least your GraphQL endpoint) is being served via an ASGI protocol server like
|
|||
|
|
daphne (built in to ``django-channels``), `uvicorn <https://www.uvicorn.org/>`_, or
|
|||
|
|
`hypercorn <https://pgjones.gitlab.io/hypercorn/>`_.
|
|||
|
|
|
|||
|
|
..
|
|||
|
|
|
|||
|
|
*** Note:** By default, the GraphiQL interface that comes with
|
|||
|
|
``graphene-django`` assumes that you are handling subscriptions at
|
|||
|
|
the same path as any other operation (i.e., you configured both
|
|||
|
|
``urls.py`` and ``routing.py`` to handle GraphQL operations at the
|
|||
|
|
same path, like ``/graphql``).
|
|||
|
|
|
|||
|
|
If these URLs differ, GraphiQL will try to run your subscription over
|
|||
|
|
HTTP, which will produce an error. If you need to use a different URL
|
|||
|
|
for handling websocket connections, you can configure
|
|||
|
|
``SUBSCRIPTION_PATH`` in your ``settings.py``:
|
|||
|
|
|
|||
|
|
.. code:: python
|
|||
|
|
|
|||
|
|
GRAPHENE = {
|
|||
|
|
# ...
|
|||
|
|
"SUBSCRIPTION_PATH": "/ws/graphql" # The path you configured in `routing.py`, including a leading slash.
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
Once your application is properly configured to handle subscriptions, you can use the GraphiQL interface to test
|
|||
|
|
subscriptions like any other operation.
