If you use server rendering, keep in mind that neither useLayoutEffect nor useEffect can run until the JavaScript is downloaded.

You might see a warning if you try to useLayoutEffect on the server. Here's two common ways to fix it.

Option 1: Convert to useEffect

If this effect isn't important for first render (i.e. if the UI still looks valid before it runs), then useEffect instead.

function MyComponent() {

import { useLayoutEffect, useCallback, useState } from 'react'

export const useRect = (ref) => {
  const [rect, setRect] = useState(getRect(ref ? ref.current : null))

  const handleResize = useCallback(() => {
    if (!ref.current) {
      return
    }

Shadow DOM

Heads Up! It's all about the V1 Spec.

In a nutshell, Shadow DOM enables local scoping for HTML & CSS.
