这几天尝试看React 官方中文文档看多了容易头疼翻看别人的都很碎片化且不是最新以至于走了很多弯路

所以我从这里开始记录从零开始如何创建一个React项目及以简单的页面跳转和传参

意在让初学者能够一步跨进React门槛 2023/5/4

这里是页面跳转传参的记录

1. Vite creates a React project

Requires node version 16 and above

Execute in sequence according to the figure. The following is a text description (CV is enough)

① Select the target folder to start the cmd command

② npm create vite

③ react-tips

④ Move the keyboard ↓ key to select React and press Enter to confirm

⑤ Select JavaScript and press Enter to confirm (of course, you can also choose TS, here we take JS as an example)

⑥ cd react-tips

⑦ asl and

⑧ npm run dev

⑨ Open the corresponding address in the browser to view the effect

The effect is as follows:

If you have created a vue project with vite, then this is familiar to you

The things on the page are self-created since they are your own projects. Naturally, these things should be cleared

The next thing we do is turn it into a pure React project and write our own content

Clear the two css files App.css and index.css

Write the contents of App.jsx

export default function App(){
return(
<>

</>
)
}

The router is used below to complete the jump between pages

Of course, the page jump naturally needs the existing page

Look at the added files and corresponding content

src/pages/home.jsx

src/pages/notFound.jsx

Use routing below

① Download the plug-in npm i react-router-dom (version 6.11.1 at this time)

npm i react-router-dom

② Create a file

src/router/index.jsx

import React,{ Suspense } from 'react'
import { BrowserRouter,Routes,Route,Navigate } from 'react-router-dom'

// 路由懒加载
const Home = React.lazy(()=>import('../pages/home'))
const NotFound = React.lazy(()=>import('../pages/notFound'))

export default function Router(){
return(
<BrowserRouter>
    <Routes>
        <Route path='/' element={<Suspense><Home/></Suspense>}></Route>
        <Route path='/home' element={<Suspense><Home/></Suspense>}></Route>
        {/* 定义404路由*/}
        <Route path='/404' element={<Suspense><NotFound/></Suspense>}></Route>
        {/* 未匹配的路由使用Navigate重定向到此页面 这里即notFound.jsx */}
        <Route path='/*' element={<Navigate to='/404' />}></Route> 
    </Routes>
</BrowserRouter>
)
}

Import and use routing

App.jsx


import Router from './router'

export default function App(){
return(
<>
<Router></Router>
</>
)
}

Effect:

Verify route jump and route redirection

home.jsx

import { useNavigate } from 'react-router-dom'

export default function Home(){
    const navigate = useNavigate()
    // 箭头函数
    const toList = ()=>{
        navigate('/list')
    }
    // 非箭头函数
    function redirectToNotFound(){
        // 随意一个没有定义的路由 验证是否重定向
        navigate('/sdf')
    }
return(
<>
<h1>this is home page</h1>
{/* 点击事件为 onClick */}
<button onClick={toList}>正常跳转至list页面</button>
<button onClick={redirectToNotFound}>重定向跳转至404页面</button>
</>
)
}

dynamic effect:
