To get the most out of this book
This book is written with the expectation that you can execute the demonstration application to understand and view the code changes that have been made in each chapter as the application is refactored. To get the most out of the book, it is recommended you read the chapters in order, as the chapters will reference code that has been modified in the previous chapter.

Most of the development for this book was done in Windows 10, but the code was tested to run in Windows Subsystem for Linux 2 (WSL 2) in Ubuntu 20.04 and tested to run on a Mac. You are expected to run the application and its dependencies within a Docker compose environment. Instructions to use Docker are given wherever possible to minimize installing new software on your machine.
If you are using the digital version of this book, we advise you to type the code yourself or access the code from the book’s GitHub repository (a link is available in the next section). Doing so will help you avoid any potential errors related to the copying and pasting of code.
