Mastering Flask Web Development - Second Edition

By: Daniel Gaspar, Jack Stouffer

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.

Summary

In this chapter, the fundamental differences between NoSQL and traditional SQL systems were laid out. We explored the main types of NoSQL systems and why an application might need, or not need, to be designed with a NoSQL database. We addressed the CAP theorem and its implications regarding modern database systems.

Using our app's models as a base, the power of MongoDB and MongoEngine was shown by demonstrating how simple it was to set up complex relationships and inheritance.

In the next chapter, our blogging application will be extended with a feature designed for other programmers who wish to use our site to build their own service—that is, RESTful endpoints.
