网站布局和建站的区别医院网站建设需求分析

1 错误信息

react 项目在创建 router 路由时，使用 lazy 懒加载时，导致以下报错：

• The above error occurred in the <Route.Provider> component:
• Uncaught Error: A component suspended while responding to synchronous input. This will cause the UI to be replaced with a loading indicator. To fix, updates that suspend should be wrapped with startTransition.

2 解决方案

懒加载模式的组件写法，外面需要套一层 Loading 的提示加载组件。

import React, { lazy } from 'react'
import { Navigate } from 'react-router-dom'// 按需引入
const Home = lazy(() => import('@/views/Home'))
const About = lazy(() => import('@/views/About'))
const User = lazy(() => import('@/views/User'))// 按需引入导致报错：懒加载模式的组件写法，外面需要套一层 Loading 的提示加载组件
const withLoadingComponent = (comp: JSX.Element) => (<React.Suspense fallback={<>Loading</>}>{comp}</React.Suspense>
)const routes = [{path: '/',element: <Navigate to='/home' />},{path: '/home',element: withLoadingComponent(<Home />)},{path: '/about',element: withLoadingComponent(<About />)},{path: '/user',element: withLoadingComponent(<User />)}
]export default routes
