Since I cant use redis I used the other channel layer that is InMemoryChannelLayer
WSGI_APPLICATION = 'django_analytics.wsgi.application'
ASGI_APPLICATION = "django_analytics.routings.application"
CHANNEL_LAYERS = {
"default": {
"BACKEND": "channels.layers.InMemoryChannelLayer",
"CONFIG": {
},
},
}
I deployed it, on heroku but I am getting error
(index):9 WebSocket connection to 'wss://mkmnim.herokuapp.com/ws/chat/page/' failed: Error during WebSocket handshake: Unexpected response code: 404
I got it working at my local server but I am not able to do the same in hosting it online,Also will I have to do something related to daphne ? Initially I used redis and ran redis server locally but while hosting redis setup was paid so I choose InMemoryChannelLayer (channels without channel layer or any other free hosting)
so what should I do ?
django_analytics.routings.py
from channels.auth import AuthMiddlewareStack
from channels.routing import ProtocolTypeRouter, URLRouter
from view_analytics import routing
application = ProtocolTypeRouter({
# Empty for now (http->django views is added by default)
'websocket': AuthMiddlewareStack(
URLRouter(
routing.websocket_urlpatterns
)
),
})
view_analytics.routings.py
from django.conf.urls import url
from . import consumers
websocket_urlpatterns = [
url(r'^ws/chat/room/$', consumers.ChatConsumer),
url(r'^ws/chat/page/$', consumers.PageConsumer),
]

let chatSocket = new WebSocket(
'wss://' + window.location.host +
'/ws/chat/' + 'page' + '/');
chatSocket.onmessage = function(e) {
const data = JSON.parse(e.data);
const message = data['message'];
console.log("message is"+ message)
};
chatSocket.onclose = function(e) {
console.error('Chat socket closed unexpectedly');
};
</script>
