I want to implement an endpoint that inserts a record into a history table. If there is no user_id associated with the history (i.e., it is the first time a history is inserted), it should return status code 201. Otherwise, it should return status code 200.

This is the only method I can think of to achieve this.

service

async putHistory(/* ... */): Promise<{ isNew: boolean; result: PutHistory }> {
  // ...
  return {
    isNew, // identifier for determining the status code
    result: {
      // ...
    },
  };
}

controller

@Put()
@HttpCode(200)
@HttpCode(201)
putHistory(@Res() res: Response): Response<any, Record<string, any>> {
  const { isNew, result } = this.historyService.putHistory(/* ... */);
  return res.status(isNew ? HttpStatus.CREATED : HttpStatus.OK).send(result);
}

However, with this method, Express Response type becomes the return type of controller, making the code look unsettling. Is there a more elegant way to write this?
