将 mern 堆栈部署到 Heroku 时如何访问 React 页面？

如何解决将 mern 堆栈部署到 Heroku 时如何访问 React 页面？

我成功地使用 react + node.js(typescript) 将应用程序部署到 Heroku，这是问题，现在我可以像 my-app.com/api/post 一样在后端访问 api，但我不知道如何访问反应页面。以下是我的构建日志

324The project was built assuming it is hosted at ./facebook/.
325You can control this with the homepage field in your package.json.

这是我的文件夹

所以经过一些研究，我认为关键是管理主页，所以我用 facebook 在客户端的 package.json 中添加主页，我认为它会像 my-app.com/facebook 一样工作，但它不起作用，我是这个部署方面的新手，所以有人知道如何访问 Heroku 上的前端页面吗？
