What are some examples of async middleware in Django?

Django async middleware allows you to handle requests asynchronously. Examples include logging, authentication, and CORS handling.

Can you provide a code example for an async middleware?

Sure! Here's a simple example:

from django.utils.deprecation import MiddlewareMixin

class AsyncMiddleware(MiddlewareMixin):
    async def __call__(self, request):
        # Do something before the view
        response = await super().__call__(request)
        # Do something after the view
        return response

How does this middleware improve performance?

Async middleware can handle multiple requests concurrently, reducing wait times and improving overall performance.

Are there any limitations to using async middleware?

Yes, not all Django features are async-compatible, and using async middleware may require careful management of database connections.
