Exposing the task manager to the frontend

We have implemented the required services for the task manager. Now, we can use the techniques we learned in the previous section, Writing a non-blocking asynchronous endpoint, to expose them to the frontend. Following the same pattern we used for the service implementation, we are going to create three resource controller classes, one for each entity: UserResource, ProjectResource, and TaskResource.

UserResource

This resource will expose the public operations of the UserService class, allowing the HTTP API consumers to perform actions dealing with the users of the task manager. We’ll start by creating a new UserResource class in the com.example.fullstack.user package. The following code snippet contains the relevant part to declare the newly created class and its constructor (you can find the complete code in the GitHub repository at https://github.com/PacktPublishing/Full-Stack-Quarkus-and-React/blob/main/chapter-03/src/main...
