node.js - 如何在 Javascript 文件中导入 Typescript 文件并在使用前解释其内容？

问题描述

我正在用 Typescript 编写一个 Node 应用程序，但我的 Cucumber 测试是用 Javascript 编写的。我的问题：如果我有一个 Typescript 文件：

import { Request, Response } from "express";
import checkCredentials from "./components/member/check-member-credentials";
import findMemberByEmail from "./components/member/find-member-by-email";

export default async (req: Request, res: Response) => {
  const memberByEmail = await findMemberByEmail(req.body.password);
  if (memberByEmail.error) {
    return res.status(401).json({ message: "not found" });
  }

  const isMatch = await checkCredentials(
    memberByEmail.member.password,
    req.body.password,
  );
  if (isMatch) {
    return res.status(200).json({ message: "logged in" });
  }
  return res.status(401).json({ message: "not auth" });
};

我正在尝试将其导入 Cucumber 测试的上下文文件中：

require('../../../../src/controllers/login.ts');

我得到典型的 js 错误：

import { Request, Response } from "express";
       ^
SyntaxError: Unexpected token {

我尝试使用一个库typescript-require并在导入之前需要它（如其文档中所示）：

require('typescript-require');
const login = require("../../../../src/controllers/login.ts");

但我仍然收到错误：

还有其他解决方案吗？
