@UseFilters(new ExceptionsFilter())
export class PhotoController {
  // ...
}

Method Decorator

// ...
import { ExceptionsFilter } from '@concepta/nestjs-exception';

@Post()
@UseFilters(new ExceptionsFilter())
async create(@Body() createPhotoDto: CreatePhotoDto) {
  throw new ForbiddenException();
}

Global Filter

// ...
import { ExceptionsFilter } from '@concepta/nestjs-exception';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.useGlobalFilters(new ExceptionsFilter());
  await app.listen(3000);
}
bootstrap();
