在JS文件中导入TS文件nodejs找不到模块

Question

我正在将 NodeJS 项目迁移到 Typescript。我已经创建了配置，它运行s 只有 JS。我在开发环境中使用 @babel/node 到运行它，但是当我尝试将 TS 文件导入 JS 时它不起作用。

它抛出以下错误：

Error: Cannot find module './findById'
Require stack:
- src/CDBR/dynamicJob/infrastructure/repository/DynamicJobPGRepository.js
- src/CDBR/dynamicJob/infrastructure/DynamicJobModule.js
- src/Main.js
- src/index.js

这是我声明函数的 TS 文件：

const findById = async (dynamicId: string, database: Postgresql) => {
    ...
};

export default findById;

这是我尝试导入它的 JS 文件：

import findById from './findById';

已解决：我必须将“@babel/plugin-transform-runtime”添加到 .babelrc 插件属性并将入口点更改为我的应用程序。这是现在的样子：

require('core-js/stable');
require('regenerator-runtime/runtime');

require('@babel/register')({
  extensions: ['.js', '.ts'],
});

const Main = require('./Main').default;

const start = async () => {
  try {
    const app = new Main();

    await app.initConfig();
    app.initContainer();
    app.initServer();
  } catch (error) {
    console.error(error);
    process.exit(1);
  }
};

start();
