Summary

In this chapter, we have learned how to use Reactive support (Flux and Mono) and how to integrate our APIs with Reactive components. We have learned basic CRUD operations on Reactive-based REST APIs with the help of the Reactor server. Also, we have covered how to add routing options for our CRUD operations and talked a little bit about Flux and Mono implementations in our CRUD operations.

In the coming chapters, we will be focusing on Spring 5 REST (without Reactor support), as Spring Reactive libraries/APIs are still in unstable mode and haven't been used much in mainstream applications. Though the Spring team officially released support for Reactive, most business requirements are not clearly implemented and documented. Considering this situation, in upcoming chapters we will talk about Spring 5 without Reactive-related topics.
