Does Django use WSGI or ASGI?

Django currently supports two interfaces: WSGI and ASGI. WSGI is the main Python standard for communicating between web servers and applications, but it only supports synchronous code.

What is WSGI and ASGI in Django?

ASGI stands for Asynchronous Server Gateway Interface. It extends the capabilities of WSGI (Web Server Gateway Interface), which is a standard way of communication between the web server and the web applications in most of the python web frameworks like Django.

What is Django ASGI?

A successor to WSGI, the ASGI specification in Python is a superset of WSGI and can be a drop-in replacement for WSGI. Django allows for an “async outside, sync inside” mode that allows your code to be synchronous internally, while the ASGI server handles requests asynchronously.

Can Daphne run WSGI?

If that’s the case, that’s fine; you can run Daphne and a WSGI server alongside each other, and only have Daphne serve the requests you need it to (usually WebSocket and long-poll HTTP requests, as these do not fit into the WSGI model).

How does ASGI work in Python?

ASGI consists of two different components: A protocol server, which terminates sockets and translates them into connections and per-connection event messages. An application, which lives inside a protocol server, is instanciated once per connection, and handles event messages as they happen.

What is WSGI vs ASGI?

ASGI is a spiritual successor to WSGI, the long-standing Python standard for compatibility between web servers, frameworks, and applications. WSGI succeeded in allowing much more freedom and innovation in the Python web space, and ASGI’s goal is to continue this onward into the land of asynchronous Python.

Does Gunicorn support ASGI?

Running with Gunicorn Gunicorn is a mature, fully featured server and process manager. Uvicorn includes a Gunicorn worker class allowing you to run ASGI applications, with all of Uvicorn’s performance benefits, while also giving you Gunicorn’s fully-featured process management.

What is Asgiref Django?

ASGI is a standard for Python asynchronous web apps and servers to communicate with each other, and positioned as an asynchronous successor to WSGI. This package includes libraries for implementing ASGI servers. Website: https://github.com/django/asgiref/ License: Modified BSD. Package source: python-web.scm.

How does WSGI work in Django?

Django’s primary deployment platform is WSGI, the Python standard for web servers and applications. Django’s startproject management command sets up a minimal default WSGI configuration for you, which you can tweak as needed for your project, and direct any WSGI-compliant application server to use.

Why does Python need WSGI?

WSGI is a standard described on PEP 3333 and basically, provides a standard interface between web applications written in Python and Webservers. That means, WSGI gives portability to your Python Web Application across many different Web Servers, without any additional configurations on your NGINX, Apache, etc.

How does ASGI work?

What ASGI servers can Django talk to?

This allows it to talk to all known ASGI servers such as: Hypercorn – an ASGI server based on the sans-io hyper, h11, h2, and wsproto libraries It is important to reiterate that internally Django is still processing requests synchronously in a threadpool.

Is it possible to use asyncio with WSGI?

Yes, it is as straightforward as taking your existing wsgi.py and running a string replacement s/wsgi/asgi/g. You should take care not to call any sync code in the ASGI Handler in your asgi.py. For example, if you make a call to some web API within your ASGI handler for some reason, then it must be an asyncio callable.

What is the difference between ASGI and WSGI?

The ASGI performance is much more stable even after failures. As the table shows, the number of simultaneous users is around 300 for WSGI and 500 for ASGI on my machine. This is about 66\% increase in the number of users the servers can handle without error. Your mileage might vary.

What is the WSGI server used for?

WSGI server has served an important purpose to make deployment of web applications easy for a web framework like Flask or Django as part of backend infrastructure instead of a full-stack solution due to the raise of frontend web framework like Angular, React and Vue.
