使用antd按需加载
使用react-app-rewired对 create-react-app 的默认配置进行自定义
1、yarn add react-app-rewired --dev
/* package.json */"scripts": {- "start": "react-scripts start",+ "start": "react-app-rewired start",- "build": "react-scripts build",+ "build": "react-app-rewired build",- "test": "react-scripts test --env=jsdom",+ "test": "react-app-rewired test --env=jsdom",} 2.然后在项目根目录创建一个 config-overrides.js 用于修改默认配置。
module.exports = function override(config, env) { // do stuff with the webpack config... return config;}; 使用 babel-plugin-import
babel-plugin-import 是一个用于按需加载组件代码和样式babel 插件（原理），现在我们尝试安装它并修改config-overrides.js 文件
1.yarn add babel-plugin-import --dev
+ const { injectBabelPlugin } = require('react-app-rewired'); module.exports = function override(config, env) {+ config = injectBabelPlugin(['import', { libraryName: 'antd', libraryDirectory: 'es', style: 'css' }], config); return config; }; 或者也可修改
{ test: //.(js|jsx|mjs)$/, include: paths.appSrc, loader: require.resolve('babel-loader'), options: { plugins: [ ['import', { libraryName: 'antd', style: true }], ], // This is a feature of `babel-loader` for webpack (not Babel itself). // It enables caching results in ./node_modules/.cache/babel-loader/ // directory for faster rebuilds. cacheDirectory: true, }, }, 自定义主题
yarn add react-app-rewire-less --dev
const { injectBabelPlugin } = require('react-app-rewired');+ const rewireLess = require('react-app-rewire-less'); module.exports = function override(config, env) {- config = injectBabelPlugin(['import', { libraryName: 'antd', style: 'css' }], config);+ config = injectBabelPlugin(['import', { libraryName: 'antd', style: true }], config);+ config = rewireLess.withLoaderOptions({+ modifyVars: { "@primary-color": "#1DA57A" },+ })(config, env); return config; }; 参考链接：https://ant.design/docs/react/use-with-create-react-app-cn
使用less
如果已经配置react-app-rewire-less，则无需再进行此操作
1.npm install less-loader less --save-dev
2.修改node_modules/react_script/config下的webpack.config.dev.js 和 webpack.config-prod.js 配置文件
- test: /.css$/ 改为 /.(css|less)$/
- test: /.css$/ 的 use 数组配置增加 less-loader
{ test: //.(css|less)$/, use: [ require.resolve('style-loader'), { loader: require.resolve('css-loader'), options: { importLoaders: 1, }, }, { loader: require.resolve('postcss-loader'), options: { // Necessary for external CSS imports to work // https://github.com/facebookincubator/create-react-app/issues/2677 ident: 'postcss', plugins: () => [ require('postcss-flexbugs-fixes'), autoprefixer({ browsers: [ '>1%', 'last 4 versions', 'Firefox ESR', 'not ie < 9', // React doesn't support IE8 anyway ], flexbox: 'no-2009', }), ], }, }, { loader: require.resolve('less-loader') // compiles Less to CSS } ],}, 使用css Module
antd 和 css modules 不能混用,针对antd的css 单独写一条loader的规则,不开启 css modules。
使用 exclude 和 include 配置,修改webpack.config.dev.js 和 webpack.config-prod.js 配置文件 (尽量不要使用less-loader 来处理css文件，在与antd一起使用时可能出现错误，单独写一条规则)
{ test: //.css$/, exclude: /node_modules|antd/.css/, use: [ require.resolve('style-loader'), { loader: require.resolve('css-loader'), options: { importLoaders: 1, modules: true, // 新增对css modules的支持 localIdentName: '[name]__[local]__[hash:base64:5]', }, }, { loader: require.resolve('postcss-loader'), options: { // Necessary for external CSS imports to work // https://github.com/facebookincubator/create-react-app/issues/2677 ident: 'postcss', plugins: () => [ require('postcss-flexbugs-fixes'), autoprefixer({ browsers: [ '>1%', 'last 4 versions', 'Firefox ESR', 'not ie < 9', // React doesn't support IE8 anyway ], flexbox: 'no-2009', }), ], }, }, ], }, { test: //.less$/, exclude: /node_modules|antd/.less/, use: [ require.resolve('style-loader'), { loader: require.resolve('css-loader'), options: { importLoaders: 1, modules: true, // 新增对css modules的支持 localIdentName: '[name]__[local]__[hash:base64:5]', }, }, { loader: require.resolve('postcss-loader'), options: { // Necessary for external CSS imports to work // https://github.com/facebookincubator/create-react-app/issues/2677 ident: 'postcss', plugins: () => [ require('postcss-flexbugs-fixes'), autoprefixer({ browsers: [ '>1%', 'last 4 versions', 'Firefox ESR', 'not ie < 9', // React doesn't support IE8 anyway ], flexbox: 'no-2009', }), ], }, }, { loader: require.resolve('less-loader') // compiles Less to CSS }, ], }, { test: //.(css)$/, include: /node_modules|antd/.css/, use: [ require.resolve('style-loader'), { loader: require.resolve('css-loader'), options: { importLoaders: 1, }, }, { loader: require.resolve('postcss-loader'), options: { // Necessary for external CSS imports to work // https://github.com/facebookincubator/create-react-app/issues/2677 ident: 'postcss', plugins: () => [ require('postcss-flexbugs-fixes'), autoprefixer({ browsers: [ '>1%', 'last 4 versions', 'Firefox ESR', 'not ie < 9', // React doesn't support IE8 anyway ], flexbox: 'no-2009', }), ], }, }, ], }, { test: //.(less)$/, include: /node_modules|antd/.less/, use: [ require.resolve('style-loader'), { loader: require.resolve('css-loader'), options: { importLoaders: 1, }, }, { loader: require.resolve('postcss-loader'), options: { // Necessary for external CSS imports to work // https://github.com/facebookincubator/create-react-app/issues/2677 ident: 'postcss', plugins: () => [ require('postcss-flexbugs-fixes'), autoprefixer({ browsers: [ '>1%', 'last 4 versions', 'Firefox ESR', 'not ie < 9', // React doesn't support IE8 anyway ], flexbox: 'no-2009', }), ], }, }, { loader: require.resolve('less-loader') // compiles Less to CSS }, ], }, 以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持VeVb武林网。
