# create django project in my case
my project name is "project" and app name is "app"


pip install channels

# setting.py
INSTALLED_APPS = [
    'channels',
    'app'
]

ASGI_APPLICATION = "project.asgi.application"



# app/consumers.py

from channels.generic.websocket import AsyncWebsocketConsumer
import json

class ChatConsumer(AsyncWebsocketConsumer):
    async def connect(self):
        # Accepts the WebSocket connection
        await self.accept()

    async def disconnect(self, close_code):
        # Handles WebSocket disconnection
        pass

    async def receive(self, text_data):
        # Handles data received from WebSocket
        text_data_json = json.loads(text_data)
        message = text_data_json['message']

        # Echoes the received message back to the client
        await self.send(text_data=json.dumps({
            'message': message
        }))

# app/routing.py

from . import consumers
from django.urls import path
websocket_urlpatterns = [
    path("ws/chat/", consumers.ChatConsumer.as_asgi()),
]

# project/asgi.py

import os
import django
from channels.routing import ProtocolTypeRouter, URLRouter
from channels.auth import AuthMiddlewareStack
from app.routing import websocket_urlpatterns
from django.core.asgi import get_asgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')
django.setup()

application = ProtocolTypeRouter({
    "http": get_asgi_application(),
    "websocket": AuthMiddlewareStack(
        URLRouter(
            websocket_urlpatterns
        )
    ),
})

# run 
# Using Daphne
daphne -p 8000 project.asgi:application

# Or using Uvicorn
uvicorn project.asgi:application --port 8000
