In this listicle, we present severalPython web serversyou can use to deploy your Python applications.
Well start by understanding how web servers work and the need for server gateway interfaces.
Then, well go over the list of Python web servers along with their salient features.
What is a Web Server?
When developing a Python system, youll use the development server totest your app.
However, once the development is complete, youll have to deploy your app on a production-grade server.
This response may include the HTTP status code indicating whether the request was processed successfully or not.
It might consist of HTML web pages and semi-structured data such asJSON, XML, and more.
If you want to learn more about server types and functions, check out thisserver guide.
A conventional server may be unable to understand and process the requests directed to the Python program.
Heres where server gateway interfaces come into play.
The web server receives a request from a client, which it then redirects to the server gateway interface.
The interface (WSGI/ASGI) interacts with the Python system through an exposed callable.
The Web Server Gateway Interface (WSGI) handles requests sequentially.
If there are multiple slow HTTP requests, then theyll impact the throughput.
When the first request is waiting for a response, ASGI can handle a second incoming request.
This is in contrast to WSGI, where the first request must be processed before the second request.
Therefore, using ASGI may result in increased throughput.
ASGI also lets you useasynchronous Pythoncapabilities within your app.
Weve also included certain frameworks that provide out-of-the-box support for production-ready servers.
This is not an exhaustive list, and the web server recommendations below are not in any particular order.
Uvicorn is an ASGI server implementation for Python.
Uvicorn gives a Gunicorn worker class, allowing you to achieve performance and process management advantages simultaneously.
This documentation page contains details ondeploying Gunicorn.
It also has a supportivedeveloper community.
If youve developed applications with Django, youll likely have used theDaphneweb server.
Daphne is one of the first ASGI server implementations used as a reference for ASGI server implementations.
Daphne is available as a PyPI package that you might install using pip.
Heres a detailed tutorial thatll walk you through building a full-stack production-ready Python tool.
This project also has several web and HTTP Python libraries.
you’re able to load the latest release of Trio (June 2022) from PyPI.
This event-driven framework includes a module for web programming calledtwisted.web.
Heres a useful video explaining theasynchronousprogramming capabilities on the client side to speed up requests to APIs significantly.
Currently, Tornado supports Python 3.7 and later.
It uses and builds existing libraries for event handling and HTTP request processing.
Be sure to try them out in your futureprojects.
