Add async view

[fabienheureux]

Async view for django >= 3.1

Description

This is still a work in progress, but based on repl from @jkimbo (https://replit.com/@jkimbo/Graphene-async#main/schema.pyhttps://replit.com/@jkimbo/Graphene-async#main/schema.py) I got an async view working for graphene.

I think this should be part of graphene django.

You can use it like this for now

from django.conf.urls import url
from django.views.decorators.csrf import csrf_exempt
from graphene_django.views import AsyncGraphQLView

#  ... your django urls
urlpatterns += [ url(r"^graphql$", csrf_exempt(AsyncGraphQLView.as_view(schema=schema, graphiql=True)))]

🖖 any kind of help / review, even at this stage is much appreciated as I am not really experienced with graphene internals, and there might be some area for improvement here.
Thanks !

TODO

• Add examples with async resolvers
• Add tests
• Add documentation

Is it possible to mix sync and async resolvers this way?

Is it possible to mix sync and async resolvers this way?

You should be able to using @sync_to_async decorator.
As I said in the description of the PR, I don't have a strong experience with graphene / async django, but I need it in a specific project, so feel free to try it out with the code from this PR or this repo https://github.com/fabienheureux/graphene-async

I meant if one has 100 sync resolvers already and only wants to add a few async ones, how should one proceed? Even if front-end guarantees to not mix sync and async queries.

@Suor mixing Sync and async resolvers is handled directly by Graphql-Core, not by the view. So that will work.

What are the next steps on this one? It would be very helpful to have async views with graphene django 🙏🏼

Hey, sorry I have not been using this project since a few months, I am not sure when I will be able to catch up, I hope before the end of 2022 but I am buried under a lot of client work at the moment 😓
