Custom Logger

By default the library logs to the console. To use your own logger, implement the AbstractLoggerService class-interface with the logError, logWarning and logDebug methods:

import { Injectable } from '@angular/core';
import { AbstractLoggerService } from 'angular-auth-oidc-client';

@Injectable()
export class MyLoggerService implements AbstractLoggerService {
  logError(message: string | object, ...args: any[]): void {
    // ...
  }

  logWarning(message: string | object, ...args: any[]): void {
    // ...
  }

  logDebug(message: string | object, ...args: any[]): void {
    // ...
  }
}

The library filters the messages by the configured logLevel (LogLevel.None, LogLevel.Debug, LogLevel.Warn, LogLevel.Error) before it calls your logger. Errors are always passed on unless the logLevel is LogLevel.None. Warnings and debug messages are only passed on when a logLevel is set that includes them. Each message is prefixed with [ERROR], [WARN] or [DEBUG] and the configId, if there is one.

Usage

Standalone

Include the logger class within the ApplicationConfig:

export const appConfig: ApplicationConfig = {
  providers: [
    provideAuth({
      config: {
        // ...
      },
    }),
    { provide: AbstractLoggerService, useClass: MyLoggerService },
  ],
};

NgModule

Provide the logger class in the module:

@NgModule({
  imports: [
    AuthModule.forRoot({
      config: {
        // ...
      },
    }),
  ],
  providers: [{ provide: AbstractLoggerService, useClass: MyLoggerService }],
  exports: [AuthModule],
})
export class AuthConfigModule {}
