Flask is a microframework that boasts a low learning curve, a large community,

and the power to create complex web apps. It is easy to learn but difficult to

master.

Starting from a simple Flask app, this book will walk through advanced topics

while providing practical examples. A proper app structure is demonstrated by

transforming the app to use a Model-View-Controller (MVC) architecture. With a

scalable structure in hand, the next chapters use Flask extensions to provide

extra functionality to the app, including user login and registration, NoSQL

querying, a REST API, an admin interface, and more. Next, you'll discover how

to use unit testing to take the guesswork away from making sure the code is

performing as it should be. The book closes with a discussion of the different

platforms that are available to deploy a Flask app on, with the pros and cons

of each one taken into account.
