Throughout Part II we progressively built an application core and a simple example that leveraged the core. While this was instrumental in learning the concepts, we don’t recommend using this core in a production application. The core was written solely for this book as a learning device. There are better production-ready libraries for handling common functionality like managing session history, such as
history and other modules were intentionally not utilized in order to focus on learning the underlying concepts and native APIs as opposed to learning a library API. However, leveraging highly adopted and well-supported open source solutions is a good idea because these libraries will likely cover edge cases that we might not have accounted for in our code.
In Part II we emphasized creating a common request/response ...
