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 and best practices for Flask web development.

Updated to the latest version of Flask and Python 3, this second edition of Flask Framework Cookbook moves away from some of the old and obsolete libraries and introduces recipes on bleeding edge technologies. You'll discover different ways of using Flask to create, deploy, and manage microservices. 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 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 in the best possible way and scale them using standard industry practices.

• Explore web application development in Flask, right from installation to post-deployment stages
• Make use of advanced templating and data modeling techniques
• Discover effective debugging, logging, and error handling techniques in Flask
• Integrate Flask with different technologies such as Redis, Sentry, and MongoDB
• Deploy and package Flask applications with Docker and Kubernetes

About the author

Shalabh Aggarwal has more than 10 years' experience in developing and managing enterprise systems, as well as web and mobile applications for small-to large-scale industries. He started his career working on Python, and although he now works on multiple technologies, he remains a Python developer at heart. He is passionate about open source technologies and writes highly readable and quality code.

He is also active in voluntary training for engineering students on non-conventional and open source topics. When not working with full-time assignments, he consults for start-ups on leveraging different technologies. When not writing code, he writes technical and non-technical literature, which is published across multiple blogs.

I would like to dedicate this book to my late father, who will always be there in my thoughts for the love and encouragement he gave me to explore new things in life. I would like to thank my family, my wife, and my mother for putting up with me during my long writing and research sessions. I would also like to thank my friends and colleagues who encouraged me and kept the momentum going.
