Summary

In this chapter, we had the opportunity to dive into more Quarkus features, especially RESTEasy Reactive. We started by reviewing what imperative and reactive mean in the context of client-server communication.

Then, we learned that Quarkus provides RESTEasy Reactive as its JAX-RS implementation, enabling us to implement Reactive endpoints on input adapters. After that, we exposed the hexagonal system’s API using OpenAPI and Swagger UI. To ensure we implemented the Reactive endpoints correctly, we wrote the endpoint tests using the rest-assured library.

In the next chapter, we’ll continue exploring the Reactive capabilities offered by Quarkus and emphasize the data persistence aspects with Hibernate Reactive.
