我正在开发一个 React-TS 应用程序。它在实时服务器中加载良好。但在本地主机的开发模式下，速度非常慢。经过一些研究后，我没有找到解决方案。这是我的包 json 文件。

我尝试删除 es-lint 和 lint 相关依赖项以及 dev/redux 工具，但问题仍然存在。 API 工作正常并按时得到响应。我认为 UI 和组件渲染存在一些问题。任何帮助和指导将不胜感激。如果您需要查看其他与代码相关的内容以找到根本原因，请告诉我。
请使用react.Memo。你正在使用 eslint。我想是的，也许 eslint 是减慢你的应用程序的一个原因。删除 eslint 然后重试。 正在关注。
我尝试过这个，它对我有用！
如果你使用chrome，只需进入devtools并选择无节流
尝试一一删除 devDependency 并检查是否有帮助？ 否则，请关闭网络应用程序的图像并检查它是否会提高性能。
