In this section, we will walk through our RESTful API server's source code and discuss the core parts to help you to understand how the server is coded and operates. Please keep in mind that we're about to cover many code-level artifacts that are specific to the Flask and Flask-RESTful frameworks, so don't get worried if, at first, some concepts do not make immediate sense.
Once you have an understanding of the foundations and an overall idea of how our sever works, you'll be in an excellent position to deepen your understanding of Flask and Flask-RESTful by consulting their respective websites (you will find links in the Further reading section). Furthermore, you will have a solid reference RESTful API server that you can rework and use as a starting point for your own future projects.
Please note that as we discuss the code, we will skip over any code and concepts that we covered in earlier chapters, such as GPIOZero.
We will start...
