So I have a Django application with React front-end through an API (django-restframework) and I would like to implement some websocket action (real time events) with Django Channels, is it better to create another server, just to websocket connections or integrate all in one application? I know it would change to ASGI, but don't know what it can causes or malfunction with HTTP connections after that. Thanks.

Top level of ASGI application stack is ProtocolTypeRouter, defined like this:
### this is in routing.py, silbling to your root urls.py
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
import <yourApp>.routing
from django.conf.urls import url
application = ProtocolTypeRouter({
# (http->django views is added by default)
'websocket': AuthMiddlewareStack(
URLRouter(
<yourApp>.routing.websocket_urlpatterns
),
),
})
Further, in your yourApp.routing.py you have to define websocket_urlpatterns like this:
### this is in your <websocketAppDir>/routing.py
websocket_urlpatterns = [re_path(r'ws/<yourApp>/(?P<whatEver>[\w\-.]+)/$', consumers.MsgSignalConsumer),]
So far the Channel part. Now HTTP protocol: Http protocol request will be passed from this ProtocolTypeRouter through to the django's standard routing, so all django hhtp requests stay 'untouched' and full in service.
Bottom line: you switch to asgi.py, in there you are defining
application = get_default_application() ### channels asgi
set up channels (ProtocolTypeRouter) - that's it.
