Daphne is a HTTP, HTTP2 and WebSocket protocol server for ASGI, and developed to power Django Channels.
It supports automatic negotiation of protocols; there's no need for URL prefixing to determine WebSocket endpoints versus HTTP endpoints.
Simply point Daphne to your ASGI channel layer instance, and optionally set a bind address and port (defaults to localhost, port 8000):
daphne -b 0.0.0.0 -p 8001 django_project.asgi:channel_layer
