Deploying asgi and wsgi on Heroku

Question

I'm trying to deploy Django Channels on Heroku using asgi alongside my existing wsgi implementation. Can I deploy both asgi and wsgi to heroku with the following setup?

My procfile:

web: gunicorn chatbot.wsgi --preload --log-file -
daphne: daphne chat.asgi:channel_layer --port $PORT --bind 0.0.0.0 -v2
chatworker: python manage.py runworker --settings=chat.settings -v2

My asgi.py file:

import os
from channels.asgi import get_channel_layer

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "chat.settings")

channel_layer = get_channel_layer()

My wsgi.py file:

import os

from django.core.wsgi import get_wsgi_application
from whitenoise.django import DjangoWhiteNoise

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "chat.settings")

application = get_wsgi_application()
application = DjangoWhiteNoise(application)

And my channel layers in settings.py:

CHANNEL_LAYERS = {
    'default': {
        "BACKEND": "asgi_redis.RedisChannelLayer",
        "CONFIG": {
            "hosts": [os.environ.get('REDIS_URL', 'redis://localhost:6379')]
        },
        'ROUTING': 'chat.routing.channel_routing',
    }
}

Figured this out, in case this might be relevant to anyone else. Using just asgi was the best solution. My procfile ended being:

web: daphne chat.asgi:channel_layer --port $PORT --bind 0.0.0.0 -v2
chatworker: python manage.py runworker --settings=chat.settings -v2

As a solution for serving static files, I updated my routing.py file to include a StaticFileConsumer.
