Overview of this book

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.

Shortening URLs using the bitly API


Our users will not want to type in the long URLs that we currently provide for calling a waiter to their table. We'll now look at using the bitly API to create shorter equivalents of the URLs that we've already created. The shorter URLs, which can be typed into address bars (especially on mobile devices) more easily, will then be shown as being associated with the corresponding tables instead of the longer ones we have now.

Introducing Bitly

The premise behind Bitly—and many similar services—is simple. Given a URL of arbitrary length, the service returns a shorter URL of the form bit.ly/XySDj72. Bitly and similar services normally have very short root domains (bit.ly is five letters), and they simply maintain a database that links the short URLs they create to the longer ones input by the users. Because they use a combination of lower- and uppercase characters as well as digits to create the shortened URLs, there is no shortage of combinations to use, even...
