The refactoring homework for this chapter will involve getting rid of unfiltered and dispatch it in the bookstore-code base and replacing it with Akka HTTP. I have done the work of creating the framework-level code that you will build on top of. I'll break down what needs to be done for both outbound and inbound HTTP changes separately, in the following sections. As always, you will do your work in the -incomplete code base, and you can consult what I did in the -complete code base if you get stuck.
