与React中的useEffect挂钩连接。我的目标是结合客户端渲染,同时确保防止React水合错误。
据我所知,客户端渲染需要在客户端的浏览器上而不是服务器上渲染组件,从而提高了性能和交互性。然而,在过渡到客户端侧渲染期间,由于初始服务器侧渲染的HTML和后续客户端侧渲染的组件之间的不一致性,可能出现问题,导致React水合错误。
考虑到这一点,我非常感谢您的指导,有效地利用useEffect钩子来实现正确的客户端渲染,而不会遇到任何react-hydration-error。我正在寻求一种专业的方法来应对这一挑战,并将感谢您能够分享的任何最佳实践、策略或代码示例。
提前感谢您的宝贵帮助。
这是我的示例代码:

"use client"
import Image from 'next/image';
import Link from 'next/link';
import React, { useState, useEffect } from 'react';
import { AiOutlineClose, AiOutlineMenu } from 'react-icons/ai';
import { motion, useScroll } from 'framer-motion';
import logo from '../public/logo_navbar_adobe_express.svg';
import { variants } from '../utils/motion';
import { BsArrowRightCircle } from 'react-icons/bs'
import styles from '../styles';
function useWindowSize(nav, setNav) {
const [windowSize, setWindowSize] = useState([0, 0]);
useEffect(() => {
function updateWindowSize() {
setWindowSize([window.innerWidth, window.innerHeight]);
if (window.innerWidth >= 768 && nav) {
setNav(false);
}
}
window.addEventListener('resize', updateWindowSize);
updateWindowSize();
return () => window.removeEventListener('resize', updateWindowSize);
}, [nav, setNav]);
return windowSize;
}
const Navbar = () => {
const [nav, setNav] = useState(false);
const windowSize = useWindowSize(nav, setNav);
const isMobile = windowSize[0] < 768;
const handleNav = () => {
setNav(!nav);
};
/** this hook gets the scroll y-axis **/
const { scrollY } = useScroll();
/** this hook manages state **/
const [hidden, setHidden] = React.useState(false);
/** this onUpdate function will be called in the `scrollY.onChange` callback **/
function update() {
if (scrollY?.current < scrollY?.prev) {
setHidden(false);
} else if (scrollY?.current > 100 && scrollY?.current > scrollY?.prev) {
setHidden(true);
}
}
/** update the onChange callback to call for `update()` **/
useEffect(() => {
return scrollY.onChange(() => update());
}, [scrollY]); // Add scrollY as a dependency
return (
<motion.nav
variants={variants}
initial="hidden"
animate={hidden ? 'hidden' : 'visible'}
/** I'm also going to add a custom easing curve and duration for the animation **/
transition={{ ease: [0.1, 0.25, 0.3, 1], duration: 0.6 }}

useWindowSize函数似乎正在触发react-hydration-error
