我在我的應用程式上收到 R14 警告，所以我確實將我的應用程式減少到僅主頁以跟蹤問題但發生的情況是警告仍然有任何想法可能導致此問題？我有點擔心我的 package.json 是錯誤的，所以基本上我的應用程式只是主頁沒有功能，這可能是我的啟動腳本錯誤并且應用程式在 dev 中啟動？我也有嚴格模式的問題，如何在生產中禁用嚴格模式？我不得不注釋掉嚴格模式，因為應用程式出于某種原因被部署在嚴格模式下？

}uj5u.com熱心網友回復：
您的start腳本運行react-scripts start：
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject"
},
這幾乎肯定是錯誤的。
假設這是一個獨立的應用程式，React 實際上不應該在 Heroku上運行。相反，您應該在編譯時構建一個生產版本，然后 Heroku 只需要將您的檔案托管為靜態檔案。它使用非常少的記憶體。
一種選擇是使用這個 buildpack，它承諾以零配置的方式通過create-react-app在 Heroku上啟動和運行創建應用程式：
此 buildpack 將 React UI 部署為靜態網站。在Nginx的網路服務器提供了運行時的最佳性能和安全性。
配置您的應用程式以使用此 buildpack：
heroku buildpacks:set mars/create-react-app
然后重新部署。
