这是一套Typescript React Antd的通用后台管理系统的视频，我会在这个视频里面带着大家徒手搭了一套基于react的后台管理系统基础设施，之所以叫通用，是因为不管以后做什么类型的管理系统，都可以直接拿这一套代码快速上手项目。

一：UI组件库：Antd的初步使用

使用 npm 或 yarn 或 pnpm 安装

我们推荐使用 npm 或 yarn 或 pnpm 的方式进行开发，不仅可在开发环境轻松调试，也可放心地在生产环境打包部署使用，享受整个生态圈和工具链带来的诸多好处。

安装Antd Design

代码语言：javascript复制
npm install antd --save

安装图标需要的模块

代码语言：javascript复制
npm install --save @ant-design/icons

打开package.json

打开文档 复制一个组件按钮的代码

代码语言：javascript复制
import { Button } from 'antd';
<Button type="primary">Primary Button</Button>

二：React路由配置

配置方案1，旧项目中的写法，按照组件思路来写

新建文件夹router/index.tsx

代码语言：javascript复制
import App from "../App"

import Home from "../views/Home"
import About from "../views/About"
import {BrowserRouter,Routes,Route} from "react-router-dom"


const baseRuter=()=>(
    <BrowserRouter>
    <Routes>
        <Route path="/"  element={<App/>}>
            <Route path="/home"  element={<Home/>}></Route>
            <Route path="/about"  element={<About/>}></Route>
        </Route>
    </Routes>
    </BrowserRouter>
)

export  default baseRuter

新建文件views/About.tsx/Home.tsx

Home.tsx

代码语言：javascript复制
function View() {
    return (
        <div className='home'>
            <p>这是home组件</p>
        </div>
    )
}
export default View

About.tsx

代码语言：javascript复制
function View() {
    return (
        <div className='home'>
            <p>这是about组件</p>
        </div>
    )
}

export default View

组件main.tsx挂载

代码语言：javascript复制
import React from 'react'
import ReactDOM from 'react-dom/client'
//正确的样式引入顺序
//1：样式初始化一般放在最前
import "reset-css"
//2:ui框架的样式
//全局样式
//import "./assets/styles/global.scss"
import "@/assets/styles/global.scss"

import Router from "./router"

//3：组件的样式
// import App from './App.tsx'

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <Router />
  </React.StrictMode>,
)

顶级组件App.tsx

代码语言：javascript复制
import { useState } from 'react'

import { Outlet, Link } from 'react-router-dom';
function App() {
  const [count, setCount] = useState(0)
  return (
    <div className='App'>
      <Link to="/home">Home</Link>
      <Link  to="/about"> About</Link>

      <Outlet></Outlet>

    </div>
  )
}

export default App

访问：

路径重定向问题，打开就跳转到home index.tsx

代码语言：javascript复制
import App from "../App"

import Home from "../views/Home"
import About from "../views/About"
import {BrowserRouter,Routes,Route,Navigate} from "react-router-dom"


const baseRuter=()=>(
    <BrowserRouter>
    <Routes>
        <Route path="/"  element={<App/>}>
            {/* 配置用户访问/的时候，重定向到/home路径 */}
            <Route   path="/"  element={<Navigate to="/home"/>}></Route>
            <Route path="/home"  element={<Home/>}></Route>
            <Route path="/about"  element={<About/>}></Route>
        </Route>
    </Routes>
    </BrowserRouter>
)

export  default baseRuter

配置方案2，对象的写法 新建一个user组件

代码语言：javascript复制
function View() {
    return (
        <div className='home'>
            <p>这是user组件</p>
        </div>
    )
}

export default View

App.tsx

代码语言：javascript复制
import { useState } from 'react'

import { useRoutes, Link } from 'react-router-dom';

import router from './router';

function App() {
  const [count, setCount] = useState(0)
 const ourlet =useRoutes(router)

  return (
    <div className='App'>
      <Link to="/home">Home</Link>
      <Link  to="/about"> About</Link>
      <Link  to="/user"> User</Link>
      {/* <Outlet></Outlet> */}

      {ourlet}

    </div>

  )
}

export default App

main.tsx

代码语言：javascript复制
import React from 'react'
import ReactDOM from 'react-dom/client'
//正确的样式引入顺序
//1：样式初始化一般放在最前
import "reset-css"
//2:ui框架的样式
//全局样式
//import "./assets/styles/global.scss"
import "@/assets/styles/global.scss"

import App from "./App"
import { BrowserRouter} from "react-router-dom"
//import Router from "./router"

//3：组件的样式
// import App from './App.tsx'

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <BrowserRouter>
    <App />
    </BrowserRouter>
  
  </React.StrictMode>,
)

index.tsx

代码语言：javascript复制
import Home from "../views/Home"
import About from "../views/About"

import User from "../views/User"

import { Navigate } from "react-router-dom"
const routes = [
    {
        path: "/",
        element: <Navigate to="/home" />
    },
    {
        path: "/home",
        element: <Home />
    },
    {
        path: "/about",
        element: <About />
    },
    {
        path: "/user",
        element: <User />
    },
]

export default routes

路由懒加载

代码语言：javascript复制
import React, { lazy } from "react"
import Home from "../views/Home"
// import About from "../views/About"

// import User from "../views/User"

const About = lazy(() => import("../views/About"))
const User = lazy(() => import("../views/User"))

import { Navigate } from "react-router-dom"

//懒加载的模式需要添加loading 组件

const routes = [
    {
        path: "/",
        element: <Navigate to="/home" />
    },
    {
        path: "/home",
        element: <Home />
    },
    {
        path: "/about",
        element: <React.Suspense fallback={<div>Loading...</div>}>
            <About />
        </React.Suspense>
    },
    {
        path: "/user",
        element:<React.Suspense fallback={<div>Loading...</div>}>
        <User />
    </React.Suspense>
    },
]

export default routes

简化

代码语言：javascript复制
import React, { lazy } from "react"
import Home from "../views/Home"
// import About from "../views/About"

// import User from "../views/User"

const About = lazy(() => import("../views/About"))
const User = lazy(() => import("../views/User"))

import { Navigate } from "react-router-dom"

//懒加载的模式需要添加loading 组件

const wifthLoadingComponent = (comp: JSX.Element) => (
    <React.Suspense fallback={<div>Loading...</div>}>
        {comp}
    </React.Suspense>
)

const routes = [
    {
        path: "/",
        element: <Navigate to="/home" />
    },
    {
        path: "/home",
        element: <Home />
    },
    {
        path: "/about",
        element: wifthLoadingComponent(<About />)
    },
    {
        path: "/user",
        element: wifthLoadingComponent(<User />)

    },
]

export default routes
react typescript import 后台 配置
