Running Django-Channels and Websockets in Production | Setup Daphne and Supervisor
Deploy Django application on Nginx and gunicorn : • Django 2.0 Deployment with Gunicorn, ...
To get your websockets running live (guaranteed) in 5 simple steps.
We setup NGINX, supervisor, daphne, asgi.py and redis to make sure it works.
If your WebSockets are running fine in local but you are having trouble with going live in production, this video is for you.
Building REST APIs over HTTP has been discussed time and again. But could we do the same with WebSockets?
