React服务端渲染警告：useLayoutEffect does nothing on the server
在React项目使用服务端渲染，如果使用了 useLayoutEffect 时，会有警告：⚠️ Warning: useLayoutEffect does nothing on the server, because its effect cannot be encoded into the server renderer's output format. This will lead to a mismatch between the initial, non-hydrated UI and the intended UI. To avoid this, useLayoutEffect should only be used in components that render exclusively on the client. See https://fb.me/react-uselayouteffect-ssr for common fixes.
