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to the latest version of Flask and Python, this third edition of the Flask Framework Cookbook moves away from the outdated libraries, updates content to incorporate new coding patterns, and introduces recipes for the latest tools.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.What you will learnExplore advanced templating and data modeling techniquesDiscover effective debugging, logging, and error-handling techniques in FlaskWork with different types of databases, including RDBMS and NoSQLIntegrate Flask with different technologies such as Redis, Sentry, and DatadogDeploy and package Flask applications with Docker and KubernetesIntegrate GPT with your Flask application to build future-ready platformsImplement continuous integration and continuous deployment (CI/CD) to ensure efficient and consistent updates to your Flask web applicationsWho this book is forIf you are a web developer seeking to expand your knowledge of developing scalable and production-ready applications in Flask, this is the book for you.
