使用Vite React React-dom-router

# npm 6.x npm init @vitejs/app vite-react-ts-antd-starter --template react-ts # npm 7+, 注意--： npm init @vitejs/app vite-react-ts-antd-starter -- --template react-ts 页面

新建pages文件夹，在文件夹下新建三个Home.tsx、About.tsx、NotFound.tsx文件：

Home.tsx:

const Home = () => { return <div> home pages </div> } export default Home

About.tsx:

const Home = () => { return <div> about pages </div> } export default Home

NotFound.tsx:

const Home = () => { return <div> 404 pages </div> } export default Home 安装路由V6

npm i react-router-dom

由于改版本改动较大，所有使用详见文档 reactrouter v6

新建router文件夹，在router文件夹下新建routes.ts:

import Home from "./../pages/Home" import About from "./../pages/About" import NotFound from "./../pages/NotFound" const Routes: any = [ { path: "/", element: Home, }, { path: "about", element: About, }, { path: "404", element: NotFound, }, ] export default Routes; 自定义History

新建history.ts:

import { createBrowserHistory } from "history"; import React from "react"; import { Router } from "react-router-dom"; export const history = createBrowserHistory(); interface IHistoryRouteProps { history: typeof history; } export const IHistoryRouter: React.FC<IHistoryRouteProps> = ({ history, children }) => { const [state, setState] = React.useState( { action: history.action, location: history.location } ); React.useLayoutEffect(() => { history.listen(setState); }, [history]); return React.createElement(Router, Object.assign({ children, navigator: history }, state)); } 使用路由

修改main.tsx:

import React from 'react' import ReactDOM from 'react-dom' import { history, IHistoryRouter } from './router/history' import './index.css' import App from './App' ReactDOM.render( <React.StrictMode> <IHistoryRouter history={history}> <App /> </IHistoryRouter> </React.StrictMode>, document.getElementById('root') )

修改App.tsx:

import React from "react"; import { useRoutes } from 'react-router-dom'; import Routes from "./router/routes" const App: React.FC = (): JSX.Element => { let routes: any = []; Routes.forEach((route: any, index: number) => { const Ele = route.element; const router = { path: route.path, element: <Ele />, }; routes.push(router); }); const router = useRoutes([...routes]); return <>{router}</>; }; export default App; Less

npm i less -D Ant Design UI

安装antd:

npm i antd-mobile

安装antd icon:

npm install -S antd-mobile-icons

按需引入：

npm i vite-plugin-imp -D 配置antd插件和CSS Modules

详细配置信息，见vite配置文档

修改vite.config.ts:

import { defineConfig } from 'vite' import react from '@vitejs/plugin-react' import vitePluginImp from "vite-plugin-imp" // https://vitejs.dev/config/ export default defineConfig({ plugins: [ react(), vitePluginImp( { optimize: true, libList: [ {//antd libName: "antd-mobile", libDirectory: "es", style: (name) => `antd/es/${name}/style`, } ], }, ), ], css: { modules: {//css modules localsConvention: "camelCaseOnly", }, preprocessorOptions: { less: { javascriptEnabled: true, } } } }) proxy代理

配置完css Modules后，在下面直接配置代理：

//... server: { proxy: { "/api/": { target: "/", changeOrigin: true, } } } //... alias别名

安装typescript版本的node：

npm i @types/node -D

接着直接根据vite文档配置：

// ... import path from 'path' //... export default defineConfig({ resolve: { alias: { "@": path.resolve(__dirname, "./src"), } }, //...

然后配置tsconfig中的compilerOptions:

//... "paths": { "@/*": ["./src/*"] } //...

然后在Home.tsx中测试以上配置：

import { history } from "../router/history"; import { Button } from "antd-mobile"; import { CheckOutline } from "antd-mobile-icons" import styles from "./Home.module.less" console.log("%c环境变量:", "color: blue; font-size: 20px;"); console.log(import.meta.env); const Home = () => { const handleClick = () => { history.push("/about"); } return <div className={styles.home}> <CheckOutline /> <Button color="primary" onClick={handleClick}>跳转</Button> <div className={styles.div}> Hello Indeex</div> </div> } export default Home

Home.module.less:

.Home{ background-color: blueviolet; .div{ background-color: lightcoral; } } 移动端适配

npm i -D postcss-pxtorem

修改vite.config:

plugins: [ react(), vitePluginImp( { optimize: true, libList: [ {//antd-mobile libName: 'antd-mobile', style: (name) => `antd-mobile/es/${name}/style/css.js` } ], }, ), ],

根目录新建postcss.config.js:

module.exports = { "plugins": { "postcss-pxtorem": { rootValue: 37.5,//对应375稿 propList: ["*"], selectorBlackList: [".norem"] } } }

在src目录下新建utils文件夹，在utiles文件夹下新建rem.js:

此步骤可直接使用 npm i -S lib-flexible

; (function(win, lib) { var doc = win.document; var docEl = doc.documentElement; var metaEl = doc.querySelector('meta[name="viewport"]'); var flexibleEl = doc.querySelector('meta[name="flexible"]'); var dpr = 0; var scale = 0; var tid; var flexible = lib.flexible || (lib.flexible = {}); if (metaEl) { console.warn('将根据已有的meta标签来设置缩放比例'); var match = metaEl.getAttribute('content').match(/initial\-scale=([\d\.]+)/); if (match) { scale = parseFloat(match[1]); dpr = parseInt(1 / scale); } } else if (flexibleEl) { var content = flexibleEl.getAttribute('content'); if (content) { var initialDpr = content.match(/initial\-dpr=([\d\.]+)/); var maximumDpr = content.match(/maximum\-dpr=([\d\.]+)/); if (initialDpr) { dpr = parseFloat(initialDpr[1]); scale = parseFloat((1 / dpr).toFixed(2)); } if (maximumDpr) { dpr = parseFloat(maximumDpr[1]); scale = parseFloat((1 / dpr).toFixed(2)); } } } if (!dpr && !scale) { var isAndroid = win.navigator.appVersion.match(/android/gi); var isIPhone = win.navigator.appVersion.match(/iphone/gi); var devicePixelRatio = win.devicePixelRatio; if (isIPhone) { // iOS下，对于2和3的屏，用2倍的方案，其余的用1倍方案 if (devicePixelRatio >= 3 && (!dpr || dpr >= 3)) { dpr = 3; } else if (devicePixelRatio >= 2 && (!dpr || dpr >= 2)) { dpr = 2; } else { dpr = 1; } } else { // 其他设备下，仍旧使用1倍的方案 dpr = 1; } scale = 1 / dpr; } docEl.setAttribute('data-dpr', dpr); if (!metaEl) { metaEl = doc.createElement('meta'); metaEl.setAttribute('name', 'viewport'); metaEl.setAttribute('content', 'initial-scale=' + scale + ', maximum-scale=' + scale + ', minimum-scale=' + scale + ', user-scalable=no'); if (docEl.firstElementChild) { docEl.firstElementChild.appendChild(metaEl); } else { var wrap = doc.createElement('div'); wrap.appendChild(metaEl); doc.write(wrap.innerHTML); } } function refreshRem() { var width = docEl.getBoundingClientRect().width; //此处以适配范围为1920---5760为例 if (width / dpr < 1920) { width = 1920 * dpr; } else if (width / dpr > 5760) { width = 5760 * dpr; } var rem = width / 19.2; //使用时1rem=100px docEl.style.fontSize = rem + 'px'; flexible.rem = win.rem = rem; } win.addEventListener('resize', function() { clearTimeout(tid); tid = setTimeout(refreshRem, 300); }, false); win.addEventListener('pageshow', function(e) { if (e.persisted) { clearTimeout(tid); tid = setTimeout(refreshRem, 300); } }, false); if (doc.readyState === 'complete') { doc.body.style.fontSize = 12 * dpr + 'px'; } else { doc.addEventListener('DOMContentLoaded', function(e) { doc.body.style.fontSize = 12 * dpr + 'px'; }, false); } refreshRem(); flexible.dpr = win.dpr = dpr; flexible.refreshRem = refreshRem; flexible.rem2px = function(d) { var val = parseFloat(d) * this.rem; if (typeof d === 'string' && d.match(/rem$/)) { val += 'px'; } return val; } flexible.px2rem = function(d) { var val = parseFloat(d) / this.rem; if (typeof d === 'string' && d.match(/px$/)) { val += 'rem'; } return val; } })(window, window['lib'] || (window['lib'] = {}));

然后在main.ts中引入:

//... import "@/utils/rem"; //...

修改Home.module.less文件检测效果：

.Home{ width: 100%; background-color: blueviolet; .div{ width: 375px; background-color: lightcoral; } } axios请求

npm i -S axios

可直接在需要的地方引入，也可以自行封装

根目录新增.env文件：

NODE_ENV=development VITE_APP_NAME=dev-indeex

和和.env.prod文件：

NODE_ENV=production VITE_APP_NAME=prod-indeex

以修改环境变量名，修改后在src下新增env.d.ts:

interface ImportMetaEnv { readonly VITE_APP_NAME: string; } interface ImportMeta { readonly env: ImportMetaEnv; }

然后重启npm或yarn，通过：

console.log(import.meta.env.VITE_APP_NAME);

获取自定义的环境名，也可以不修改环境变量名，使用默认的。

以上就可以使用在移动端，如果需要PC端，需要更换antd-mobile UI库并去掉移动端CSS配置。
