Overview of this book

Flask is a popular Python framework known for its lightweight and modular design. Mastering Flask Web Development will take you on a complete tour of the Flask environment and teach you how to build a production-ready application. You'll begin by learning about the installation of Flask and basic concepts such as MVC and accessing a database using an ORM. You will learn how to structure your application so that it can scale to any size with the help of Flask Blueprints. You'll then learn how to use Jinja2 templates with a high level of expertise. You will also learn how to develop with SQL or NoSQL databases, and how to develop REST APIs and JWT authentication. Next, you'll move on to build role-based access security and authentication using LDAP, OAuth, OpenID, and database. Also learn how to create asynchronous tasks that can scale to any load using Celery and RabbitMQ or Redis. You will also be introduced to a wide range of Flask extensions to leverage technologies such as cache, localization, and debugging. You will learn how to build your own Flask extensions, how to write tests, and how to get test coverage reports. Finally, you will learn how to deploy your application on Heroku and AWS using various technologies, such as Docker, CloudFormation, and Elastic Beanstalk, and will also learn how to develop Jenkins pipelines to build, test, and deploy applications.

Useful Flask Extensions

As we have seen throughout this book, Flask is designed to be as small as possible, while still giving you the flexibility and tools needed to create web applications. However, there are a lot of features that are common to many web applications, which means that many applications will require code that does the same task for each web application. To solve this problem, and avoid reinventing the wheel, people have created extensions for Flask, and we have seen many Flask extensions already throughout the book. This chapter will focus on some of the more useful Flask extensions that don't have enough content to separate them out into their own chapter, but will save you a lot of time and frustration.

In this chapter, you will learn how to do the following:

  • Developing a debug toolbar, with great backend performance metrics
  • Page cache using Redis or...
