我今天刚刚用这个命令创建了代码框架。

npx create-react-app my-app
cd my-app
npm start

在开发模式下,我的代码和页面性能还可以。平均50帧每秒。只有几个requestAnimationFrame警告
但是在构建后,页面性能下降,只有大约15帧每秒,错误[Violation] 'requestAnimationFrame' handler 用时 <N> 毫秒没有停止。
正常,开发环境:

我也在经历这个问题。我发现将生产环境的browserlist设置为与开发环境相同,这对我来说已经解决了问题。

"browserslist": {
    "production": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"

  },

我试过了,但对我不起作用!@jaminmelville
