NliKeycloakAuth

This library was generated with Angular CLI version 8.0.3. The library is published to the private NLI npm-repository.

Running unit tests

Run ng test nli-keycloak-auth to execute the unit tests via Karma.

Usage

You need to import the KeycloakAuthModule preferable in your app.module.ts. Then you have to execute the forRoot(baseAuthConfig: BaseAuthConfig, keycloakConfigServiceProvider?: Provider) Method. To execute the method you have to provide the BaseAuthConfig. Furthermore you can provide a provider for the KeyCloakConfigService. If not the default provider is used which will call the /config Rest-Endpoint.

Config Rest-Endpoint

The default keycloak configuration provider is a Rest-Endpoint called by this angular-framework. The Endpoint is called at /config and its structure is described at KeycloakConfig. These are:

    oauthServerUrl: string;
    keycloakRealm: string;
    disableAuth?: boolean;
    disableHttps?: boolean;

Here is an example implementation of this endpoint with spring boot, where the configuration is extracted into application.yml:

The Controller:

@RestController
@RequiredArgsConstructor
public class ConfigController {
	private final Config config;

	@RequestMapping(value = "/config", method = RequestMethod.GET, produces = "application/json")
	public Config getConfig() {
		return config;
	}
}

The provided configuration Pojo:

@Component
@Data
public class Config {
	@Value("${keycloak.auth-server-url:}")
	private String oauthServerUrl;
	@Value("${keycloak.realm:}")
	private String keycloakRealm;
	@Value("#{environment.acceptsProfiles('secure') ? false : true }")
	private boolean disableAuth;
	@Value("${disable-https-for-keycloak: false}")
	private boolean disableHttps;
}

The application.yml:

spring:
  profiles:
    active:
      - secure
keycloak:
  auth-server-url: http://localhost:8777/auth
  realm: NLI
disable-https-for-keycloak: true

Since the spring-boot backend needs the same keycloak configuration, we can avoid duplication of the configuration. (The backend uses the module af50-authorization which uses keycloak-spring-boot-2-adapter which can be configured by the same yml.)

KeycloakConfigService

If you want to set another provider you have to do the following steps: Create the service an implement the KeycloakConfigService interface. Then you hve to set the provider in the forRoot method like this MyModule.forRoot(baseAuthConfig, {provide: KeycloakConfigServiceInj, useClass: YourImplementationOfKeycloakConfigService})

BaseAuthConfig

export interface BaseAuthConfig {
    clientId: string;
    disableAuth?: boolean;
    loginTarget: string;
    logoutTarget: string;
    loginRedirectAppendix?: string;
    logoutRedirectAppendix?: string;
    manualLogin?: boolean;
}
