Summary

Hopefully, at this point, you have a good understanding of what the example is. This includes knowing how the code is structured and works as well as how to interact with it using its endpoints. You also know the big shortcomings with the app and how we plan to go about fixing them. Armed with that knowledge, you are officially ready to start our progressive refactor to building a better reactive application.

Over the next set of chapters, we will take a tour through Akka's different feature offerings above and beyond just actors. We will incorporate these features into the example app one by one in an effort to resolve the shortcomings called out in this chapter. At the end of our journey, the hope is that you will have a much deeper understanding of these newer features and be well on your way to mastering Akka.
