Building Web Applications with Flask

Packt Publishing Ltd
Free sample

Flask is a powerful web framework that helps you build great projects using your favorite tools. Flask takes the flexible Python programming language and provides a simple template for web development. Once imported into Python, Flask can be used to save time building web applications. It goes against the flow with the microframework concept, leaving most of the architecture choices to the developer. Through its great API, extensions, and powerful patterns, Flask helps you create simple projects in minutes and complex ones as soon as possible.

From the beginning, Building Web Applications with Flask shows you how to utilize Flask's concepts, extensions, and components to create engaging, full-featured web projects. You'll learn how to properly handle forms using WTForms, devise convenient templates with Jinja2 tags and macros, use NoSQL and SQL databases to store user data, test your projects with features and unit tests, create powerful authentication and user authorization, as well as administrative interfaces with ease, and more.

As Flask does not enforce an architectural recipe, neither do we! This book makes no coding assumptions on how you should code, leaving you free to experiment.

Unleash the full potential of the Flask web framework by creating simple yet powerful web applicationsAbout This BookThe most up-to-date book on Flask on the marketCreate your own world-class applications and master the art of Flask by unravelling its enigma through this journeyThis step-by-step tutorial is packed with examples on blending different technologies with Flask to get you up and runningWho This Book Is For

Have you looked at PHP and hated the clunky bloated syntax? Or looked at .Net and wished it was more open and flexible? Maybe you've tried your hand at GUI libraries in Python and found them hard to use? If your answer to any one of these questions is a yes, then this is just the book for you.

It is also intended for people who know the basics of Python and want to learn how to use it to build powerful solutions with a web front-end.

What You Will LearnBuild three web applications from the ground up using the powerful Python micro framework, Flask.Dynamically display data to your viewers, based on their requestsStore user and static data in SQL and NoSQL databases and use this data to power your web applicationsCreate a good user experience by combining HTML, CSS, and JavaScriptHarness the convenience of freely available APIs, including OpenWeatherMap, Open Exchange Rates, and bitlyExtend your applications to build advanced functionality, such as a user account control system using Flask-LoginLearn about web application security and defend against common attacks, such as SQL injection and XSSIn Detail

This book will take you on a journey from learning about web development using Flask to building fully functional web applications. In the first major project, we develop a dynamic Headlines application that displays the latest news headlines along with up-to-date currency and weather information. In project two, we build a Crime Map application that is backed by a MySQL database, allowing users to submit information on and the location of crimes in order to plot danger zones and other crime trends within an area. In the final project, we combine Flask with more modern technologies, such as Twitter's Bootstrap and the NoSQL database MongoDB, to create a Waiter Caller application that allows restaurant patrons to easily call a waiter to their table. This pragmatic tutorial will keep you engaged as you learn the crux of Flask by working on challenging real-world applications.

Style and approach

This book will provide you with rich, practical experience of Flask. Every technology, that is employed along with Flask is comprehensively introduced, while the book focusses on developing web applications. Pointers to educational material are always given if you want to gain in-depth knowledge of the various technologies used.
