Harnessing the full power of Flask will allow you to create complex web applications with ease.What You Will LearnSet up a best practices Python environmentUse SQLAlchemy to programmatically query a databaseDevelop templates in JinjaSet up an MVC environment for FlaskDiscover NoSQL, when to use it, when not to, and how to use itDevelop a custom Flask extensionUse Celery to create asynchronous tasksIn DetailFlask is a library that allows programmers to create web applications in Python. Flask is a micro-framework that boasts a low learning curve, a large community, and the power to create complex web apps. However, Flask 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 of the lessons learned. After building a simple Flask app, 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. The book closes with a discussion of the different platforms that are available to deploy a Flask app on, the pros and cons of each one, and how to deploy on each one.Style and approachWith plenty of useful examples, this guide introduces new concepts and then shows you how those concepts can be used in a real-world environment. Most sections are based around a single example app that is developed throughout the book.
