Hey @kezabelle — no urgency, but wondering if you'd be interested by 79abfaeb2047cc7972017fe8165411d8e49a6f9d... 🤔 — it's a question of what's the minimum to bootstrap the app registry here?, preferably without going all the way to pytest-django etc. That seems to me your kind of ballpark. 😜

(Hope you're doing well!)

Hey @massover — I've moved the runserver command from Channels here.

With a...

INSTALLED_APPS = [
    "daphne",
    ...
]

... it all seems to be working.

I don't know if you've got a cycle to glance over for any gains? (No problem if not 🎁)

I looked over your standalone implementation but didn't want to add the run_wsgi like options here (at this stage). The final version, living in Django, eventually, one day, maybe 😜, will need to handle both protocols.

OK, I'm going to merge this as is, so that I can continue working. We can follow up with adjustments later if needed.

Nice one!! @carltongibson Tested, seems to work just fine with the psycopg3 PR as well! https://github.com/django/django/pull/15687

For those following along:

1. python3 -m pip install git+https://github.com/django/daphne.git@7453ad9
2. In settings.py

   INSTALLED_APPS = [
   "daphne",
   #...
   ]
   #WSGI_APPLICATION = 'crdbtest.wsgi.application'
   ASGI_APPLICATION = 'crdbtest.asgi.application'

3. python3 ./manage.py runserver

@gnat Thanks for testing! (More helpful than you think 🙂)
