@Module({

    FirebaseMessagingModule.forRootAsync({
      imports: [ConfigModule],
      useFactory: async (configService: ConfigService) => {
        return {
          projectId: configService.getProjectId(),
          privateKey: configService.getPrivateKey(),

export class NotificationModule implements OnModuleInit {
  constructor(
    @Inject(FirebaseMessagingModule.PUSH_NOTIFICATION_SERVICE)
    private readonly pushNotificationService: IPushNotificationService,
  ) {}

  public async onModuleInit() {
    const notification = new NotificationBuilder()
      .setTitle('title')
      .setBody('body')
      .build();
