我正在使用 NextJS 和 Typescript 开发一个应用程序，并尝试确定正确键入 MySQL 响应的最佳方法。这是 API 端点：

import { hash } from "bcrypt";
import type { NextApiRequest, NextApiResponse } from "next";
import randomstring from "randomstring";

import { executeQuery } from "../../../lib/db";

const Test = async (req: NextApiRequest, res: NextApiResponse) => {
  // Manage password generation
  const password = randomstring.generate(16);
  const hashedPassword = hash(password, 10);

  // Create new auth using email and password
  const auth = await executeQuery(
    "INSERT INTO auth (email, password) VALUES (?, ?)",
    ["test@test.com", (await hashedPassword).toString()]
  );

  res.statusCode = 200;
  res.json(auth.insertId);
};

export default Test;

我想强类型 insertId 通过 ESLint 删除所有警告和错误，但不幸的是，我所做的一切努力都没有成功。我收到的错误是：

Property 'insertId' does not exist on type 'RowDataPacket[] | RowDataPacket[][] | OkPacket | OkPacket[] | ResultSetHeader | { error: unknown; }'.
  Property 'insertId' does not exist on type 'RowDataPacket[]'.ts(2339)

我的executeQuery函数定义为：

import mysql from "mysql2/promise";

export const executeQuery = async (query: string, params: unknown[] = []) => {
  try {
    const db = await mysql.createConnection({
      host: process.env.MYSQL_HOST,
      database: process.env.MYSQL_DATABASE,
      user: process.env.MYSQL_USER,
      password: process.env.MYSQL_PASSWORD,
    });

    const [results] = await db.execute(query, params);
    db.end();

    return results;
  } catch (error) {
    return { error };
  }
};

我的实现尝试之一是这个 SO 响应，但我无法让它工作......

非常感谢任何和所有帮助！
