Book Description

Flask, the lightweight Python web framework, is popular due to its powerful modular design that lets you build scalable web apps. With this recipe-based 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 3, this third edition of Flask Framework Cookbook moves away from some of the old and obsolete libraries, updates almost all content to use the new coding patterns and introduces some recipes on the latest tools in the market. You’ll discover different ways of using Flask to create, deploy, and manage microservices using AWS, GCP and Kubernetes. This Flask Python book starts by covering the different configurations that a Flask application can make use of, and then helps you work with templates and learn about the ORM and view layers. You’ll also be able to write an admin interface and get to grips with testing using factory pattern, debugging and logging errors. Finally, you’ll grasp a variety of deployment and post-deployment techniques for platforms such as Apache, Tornado, and Heroku.

By the end of this book, you’ll have gained all the knowledge you need to write Flask applications to suit most use cases in the best possible way and scale them using standard industry practices.
