import { AppController } from './app.controller';
import { AppService } from './app.service';

@Module({
  controllers: [AppController],
  providers: [

import type { IDebugService } from 'niro-health';

@Injectable()
export class AppService {
  constructor(
    @Inject('IDebugService')
    private readonly debugService: IDebugService,
  ) {}

  public log(text: string) {
    return this.debugService.log(text);
  }
}
```
