Writing HTTP REST endpoints in Quarkus

Quarkus provides several ways to implement HTTP and REST endpoints. In Chapter 1, Bootstrapping the Project, we learned about the imperative and reactive paradigms and how Quarkus can be used for both approaches. In this book, we are following the reactive approach to take advantage of its improved performance.

In the Bootstrapping a Quarkus application section of Chapter 1, Bootstrapping the Project, we initialized the project and added RESTEasy Reactive to the list of dependencies. This dependency is what will allow us to implement the reactive HTTP endpoints. As we learned, RESTEasy provides an implementation of JAX-RS based on Vert.x. One of the major advantages of RESTEasy Reactive compared to the regular RESTEasy alternatives is that it allows us to implement both blocking and non-blocking endpoints.

Although we already have the RESTEasy dependency, we’ll need additional dependencies to be able to serialize our database entities...
