Django-Async-Stream

Django extension that allow using asynchronous generators in StreamingHttpResponse

Usage

django-async-stream provides AsyncStreamingHttpResponse class, that you can use instead of StreamingHttpResponse

But for this to work, you need to override one method in the ASGIHandler.

asgi.py, one of the possible options

# django default file content
import os

from django.core.asgi import get_asgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'projectname.settings')

application = get_asgi_application()

#  PATCH BELOW
import django_async_stream
django_async_stream.patch_application(application)

views.py

import asyncio

from django_async_stream import AsyncStreamingHttpResponse


async def my_view(request):
    return AsyncStreamingHttpResponse(_my_async_generator())


async def _my_async_generator():
    for i in range(10):
        yield i
        await asyncio.sleep(2)

Installation

pip install django-async-stream
