So I had to result to installing uvicorn and run my project as so: Fortunately Daphne, the ASGI server which was developed to power Django Channels, has an async runserver which we can use:
:::bash To set this up we'll have to install the `daphne` package, add `daphne` to the top of our installed apps, and set
$ uvicorn --log-level debug --reload --timeout-graceful-shutdown 0 project.asgi:application` the `ASGI_APPLICATION` setting to point to our ASGI application.
The `--reload` part is particulary important when doing development, but it :::python
does not work well when working with open connections since the server will INSTALLED_APPS = [
wait for the connection to close before reloading. This is why "daphne",
`--timeout-graceful-shutdown 0` is needed. ...
"chat", # Our app
]
ASGI_APPLICATION = "project.asgi.application"
Now we can just run `./manage.py runserver` as before and we are async ready!
