Heroku R14 没有明显原因的警告可能是严格模式问题？

Question

我的应用程序收到 R14 警告，所以我确实将我的应用程序缩减为仅主页以跟踪问题，但发生了什么警告仍然存在，不知道是什么原因造成的？我有点担心我的 package.json 是错误的，所以基本上我的应用程序只是主页，没有任何功能，可能是我的启动脚本是错误的，应用程序是在 dev 中启动的？我也有严格模式问题如何在生产中禁用严格模式？我不得不注释掉严格模式，因为应用程序出于某种原因正在以严格模式部署？

您的 start 脚本运行 react-scripts start:

"scripts": {
  "start": "react-scripts start",
  "build": "react-scripts build",
  "test": "react-scripts test",
  "eject": "react-scripts eject"
},

这几乎肯定是错误的。

假设这是一个独立的应用程序，React 实际上不应该是 Heroku 上的运行。相反，您应该在编译时构建一个生产版本，然后 Heroku 只需要将您的文件作为静态文件托管。这使用非常很少的内存。

一种选择是使用 this buildpack, which promises a zero-config way to get apps created via create-react-app up and running on Heroku:

This buildpack deploys a React UI as a static web site. The Nginx web server provides optimum performance and security for the runtime.

Configure your app to use this buildpack:

heroku buildpacks:set mars/create-react-app

然后.
