A basic & minimal example, of handling notification using websocket.
Tools
Installation
On your terminal/shell
pip3 install ibalert
sudo docker run -p 6379:6379 -d redis:5
Quiz setup
In your project's settings.py file. Add ibalert and channels to intallled apps and configure redis.
# settings.py
INSTALLED_APPS = [
...,
"ibalert",
"channels"
]
ASGI_APPLICATION = "ibalert.asgi.application"
CHANNEL_LAYERS = {
"default": {
"BACKEND": "channels_redis.core.RedisChannelLayer",
"CONFIG": {"hosts": [("localhost", 6379)]},
}
}
In your project's urls.py
...
from django.views.generic import TemplateView
urlpatterns = [
path("", TemplateView.as_view(template_name="home.html")),
...
]
In your templates directory add home.html file. (Just to make sure the app is working. Later you can implement it the way you want.)

<body>
<div class="container">
<h4 class="text-center">

<span class="badge bg-danger" id="counter">0</span>

<ul id="notifylist"></ul>
</div>
</body>
<script>
const webSocket = new WebSocket("ws://localhost:8000/notifications/")
webSocket.onclose = function (e) {
console.error("Chat socket closed unexpectedly")
}
webSocket.onopen = function (e) {
webSocket.send(JSON.stringify({ userID: 1 }))
}
webSocket.onmessage = function (action) {
const data = JSON.parse(action.data)
console.log(data.event == "Notification", data)
const nl = document.querySelector("#notifylist")
if (data.event == "Notification") {
var counter = document.getElementById("counter")
counter.innerText = data.unread_count
var el = document.createElement("li")
el.innerHTML = `<b>New Notification </b>: ${data.text}!`
nl.appendChild(el)
}
}
</script>
