从一开始，我就使用Nodejs / Typescript制作服务器。
我正在尝试部署到heroku，并且看到heroku使用了npm run build命令，因此当我从github推入heroku分支时，应该构建我的打字稿。
"scripts": {
"start": "node ./build/index.js",
"build": "npx tsc",
"local": "./node_modules/.bin/env-cmd -f ./config/dev.env tsnd --respawn app/main.ts --experimental-modules"
},
当我部署时，没有任何错误，它已构建，然后服务器启动。但是当我用邮递员执行一些请求时，服务器崩溃了

Heroku在app / build内部进行搜索，但是该构建位于根目录上，因此应该就像我在npm start ./build/index.js中传递的内容而不是./app/build/index.js
如何传递绝对路径（我尝试了--prefix）？

当我使用TypeScript部署React项目时遇到了一些问题。因此，我找到了一种解决问题的方法是使用Webpack。 Webpack将从您的Typescript文件中创建一个main.js文件，因此Heroku可以知道您部署了什么。
