} from 'angular-object-logger';

@NgModule({
  declarations: [

    ],
    consoleTarget: {
      filters: [
        { source: 'AppComponent', minlevel: 'info', maxlevel: 'fatal' },
        { source: 'HomeComponent', level: 'info' },
        { source: 'SearchComponent', levels: [ 'trace', 'debug' ] },
      ]
    },
    webTarget: {
      endpoint: 'http://localhost:4000/'
    }
  }
};

@Component({
  selector: 'app-playground',
  template: `<div></div>`
})
class AppComponent {
  constructor(
    private loggerFactory: LoggerFactoryService
  ) {
    const logger = loggerFactory.createLogger(this);

    logger.trace('string log');
    logger.debug('String format log {0}: {1}', { name: 'Andre' }, { x: 10, y: 20 });
    logger.info({ list: ['object', 'log'] });
    logger.warn('string message with exception', new Error());
    logger.error({ message: 'object with exception' }, new Error());
    logger.fatal('string log message with exception', new Error());
  }
}
