This is our final chapter, and we created a small proof-of-concept application. The purpose was to go through some of the most interesting parts and methods used in the book and see how we can combine exciting ideas to create something small but powerful.

Also, we used our existing e-commerce API to retrieve information about product items and manage our users. There was no reason to go through this process again as we can rely on third-party APIs for faster prototyping.

Through most of the chapters, we only touched the most important parts. All the necessary code can be found on the Packt Publishing website (https://www.packtpub.com/) for each chapter.
