Overview of this book

Discover what makes Flask, the lightweight Python web framework, popular, as you delve into its modular design that enables the development of scalable web apps. With this practical guide, you'll explore modern solutions, recommended design patterns, and best practices for Flask web development. Updated to the latest version of Flask and Python, this third edition of the Flask Framework Cookbook moves away from the outdated libraries, updates content to incorporate new coding patterns, and introduces recipes for the latest tools. You'll explore different ways to integrate with GPT to build AI-ready Flask applications. The book starts with an exploration of Flask application configurations and then guides you through working with templates and understanding the ORM and view layers. You’ll also be able to write an admin interface and get to grips with testing using the factory pattern, debugging, and logging errors. Then you’ll discover different ways of using Flask to create, deploy, and manage microservices using AWS, GCP, and Kubernetes. Finally, you’ll gain insights into various deployment and post-deployment techniques for platforms such as Apache, Tornado, and Datadog. By the end of this book, you'll have acquired the knowledge necessary to write Flask applications that cater to a wide range of use cases in the best possible way and scale them using standard industry practices.

Deploying with uWSGI and Nginx

For those who are already aware of the usefulness of uWSGI and Nginx, not much needs to be explained. uWSGI is a protocol as well as an application server and provides a complete stack so that you can build hosting services. Nginx is a reverse proxy and HTTP server that is very lightweight and capable of handling virtually unlimited requests. Nginx works seamlessly with uWSGI and provides many under-the-hood optimizations for better performance. In this recipe, we will use uWSGI and Nginx together to facilitate the deployment of our application.

Getting ready

We will use our application from the previous recipe, Deploying with Apache, and use the same wsgi.py file.

Now, install Nginx and uWSGI. On Debian-based distributions such as Ubuntu, they can be easily installed using the following commands:

$ sudo apt-get install nginx
$ pip install pyuwsgi

These installation instructions are OS-specific, so please refer to the respective documentation...
