Add Extensions

For our reactive crud application we want to use the following quarkus extensions:

• RESTEasy Reactive Jackson
• Hibernate Reactive with Panache
• Reactive PostgreSQL client

The execution of

$ quarkus ext add quarkus-resteasy-reactive-jackson quarkus-hibernate-reactive-panache quarkus-reactive-pg-client

should give an output like

[SUCCESS] ✅  Extension io.quarkus:quarkus-resteasy-reactive-jackson has been installed
[SUCCESS] ✅  Extension io.quarkus:quarkus-hibernate-reactive-panache has been installed
[SUCCESS] ✅  Extension io.quarkus:quarkus-reactive-pg-client has been installed

To avoid conflicts we have to remove the non-reactive RESTEasy extension which was added automatically while bootstrapping our application.

The command $ quarkus ext rm quarkus-resteasy should do it for us with following output:

[SUCCESS] ✅  Extension io.quarkus:quarkus-resteasy has been uninstalled
