React引入antd-mobile+postcss搭建移动端 React引入antd-mobile+postcss搭建移

安装antd-mobile
全局引入

npm install antd-mobile --save

在App.js引入css

import 'antd-mobile/dist/antd-mobile.css';

在jsx使用antd组件

import React from 'react'; import { Button } from 'antd-mobile'; const index = () => {return (); }export default index;

按需引入

npm install babel-plugin-import -s

安装插件，覆盖webpack配置
customize-cra配置api文档

npm install react-app-rewired customize-cra -s

package.json进行更改命令方式

"scripts": {"start": "react-app-rewired start","build": "react-app-rewired build","test": "react-app-rewired test","eject": "react-app-rewired eject"},

在根目录新建config-overrides.js

const { override, fixBabelImports } = require('customize-cra'); module.exports = override(fixBabelImports('import', {libraryName: 'antd-mobile',style: 'css',}),);

在App.js删除之前引入的css
校验是否按需引入

引入postcss px转rem

npm install lib-flexible postcss-px2rem-exclude --save

index.js导入

import 'lib-flexible'

修改config-overrides.js文件

const { override, fixBabelImports, addPostcssPlugins, addWebpackAlias} = require('customize-cra'); const path = require("path"); module.exports = override(fixBabelImports('import', {libraryName: 'antd-mobile',style: 'css',}),addPostcssPlugins([require("postcss-px2rem-exclude")({remUnit: 75, //设计图大小remPrecision: 2, //只转换到两位小数exclude: /node_modules/i //插件不需要转rem})]),addWebpackAlias({"@": path.resolve(__dirname, "src")}));

如果你需要使用less
/
自定义主题

npm install less less-loader -s

如果项目启动报错,是因为less-loader版本过高，需要卸载，安装低版本

npm install less-loader@5.0.0 -s

坑！需要注意顺序

const { override, fixBabelImports, addPostcssPlugins, addWebpackAlias, addLessLoader } = require('customize-cra'); const path = require("path"); module.exports = override(fixBabelImports('import', {libraryName: 'antd-mobile',style: true, //默认为'css'}),addLessLoader({javascriptEnabled: true,modifyVars: { "@brand-primary": "#1DA57A" }, //自定义主题}),addPostcssPlugins([require("postcss-px2rem-exclude")({remUnit: 75, //设计图大小remPrecision: 2, //只转换到两位小数exclude: /node_modules/i //插件不需要转rem})]),addWebpackAlias({"@": path.resolve(__dirname, "src")}));

补充：解决react项目引入antd-mobile导致postcss配置px转rem失效问题
今天使用了一下antd-mobile发现我之前配置的postcss失效了，防止下次踩坑记录一下解决方案
解决方案：在config-overrides.js文件里重写postcss，加入如下代码
npm下载以下模块

npm i react-app-rewire-postcss postcss-px2rem-exclude -S

const {override,fixBabelImports,addWebpackAlias,addDecoratorsLegacy,} = require("customize-cra"); const path = require("path"); const rewirePostcss = require("react-app-rewire-postcss"); module.exports = override(// 配置按需加载fixBabelImports("import", {libraryName: "antd-mobile",style: "css",}),// 配置文件别名addWebpackAlias({"@": path.resolve(__dirname, "src"),"@scss": path.resolve(__dirname, "src/assets/scss"),"@images": path.resolve(__dirname, "src/assets/images"),"@views": path.resolve(__dirname, "src/views"),"@network": path.resolve(__dirname, "src/network"),"@store": path.resolve(__dirname, "src/store"),"@components": path.resolve(__dirname, "src/components"),}),addDecoratorsLegacy(),(config, env) => {// 重写postcssrewirePostcss(config, {plugins: () => [require("postcss-flexbugs-fixes"),require("postcss-preset-env")({autoprefixer: {flexbox: "no-2009",},stage: 3,}),require("postcss-px2rem-exclude")({// 设计稿宽度/10remUnit: 1080 / 10,exclude: /node-modules/i,}),],}); return config; });
