JHipster Angular with Keycloak: Missing keycloak-angular and keycloak-js in Frontend Generation

[YassineOularbi]

Why doesn't the JHipster generator generate Angular with keycloak-angular and keycloak-js when Keycloak is the identity provider, and is there any tutorial or documentation on how to integrate them?

We made a design decision years ago to do all OAuth authentication on the backend with Spring Boot. This is more secure, doesn't require us to use different OIDC libraries for front-end frameworks, and works with most OAuth providers. We don't want to force our users to use Keycloak, especially in production.

When you select oauth2 during generation it will create a keycloak config and docker file.

Without using those libraries, some issues arise. For example, when signing out from the JHipster interface in the Gateway, the backend session is destroyed, but the session in Keycloak remains active. Similarly, in JHipster Registry, logging out triggers the event listener in the Keycloak interface, resulting in a "Logout ERROR."

If we can't track login and logout events from Keycloak, we can still save user sessions and track their activities using alternative approaches.
