create-react-app+antd+less开发环境基础配置方法

Step1:使用create-react-app建立项目

1. yarn create react-app my-test-app

 

Step2:暴露webpack配置

1. 在my-test-app目录下执行:yarn eject  (无法启动的话,删除node_modules目录与yarn.lock后重新执行yarn)

2. 执行完毕后可以看到项目中多了一些文件夹,进入config目录可以找到webpack.config.js,即我们之后需要修改配置的文件。

 

Step3:配置less

1. 安装:yarn add less less-loader --save-dev

2. 打开webpack.config.js, 找到:

// style files regexes
.....
// 添加less解析规则
const lessRegex = /\.less$/;
const lessModuleRegex = /\.module\.less$/;
3. 在module -> rules中增加:
// Less 解析配置
{
test: lessRegex,
exclude: lessModuleRegex,
use: getStyleLoaders(
{
importLoaders: 1,
sourceMap: isEnvProduction && shouldUseSourceMap,
},
'less-loader'
),
sideEffects: true,
},
{
test: lessModuleRegex,
use: getStyleLoaders(
{
importLoaders: 1,
sourceMap: isEnvProduction && shouldUseSourceMap,
modules: true,
getLocalIdent: getCSSModuleLocalIdent,
},
'less-loader'
)
},

2. 打开webpack.config.dev.js文件(prod文件与之类似):

(找到如下代码段,并修改高亮处的代码)

(1)第一处(注意要按照style-loader,css-loader,postcss-loader,less-loader的顺序

{
    test: /\.(css|less)$/,
    use: [
        require.resolve('style-loader'),
        {...},
        {
            loader: require.resolve('less-loader'),
        },
    ],
},
(2)第二处
{
    // Exclude `js` files to keep "css" loader working as it injects
    // its runtime that would otherwise processed through "file" loader.
    // Also exclude `html` and `json` extensions so they get processed
    // by webpacks internal loaders.
    exclude: [
        /\.(js|jsx|mjs)$/,
        /\.html$/,
        /\.json$/,
        /\.(css|less)$/,
    ],
    loader: require.resolve('file-loader'),
    options: {
         name: 'static/media/[name].[hash:8].[ext]',
    },
},
 
// ****************************************8
 

Step4:配置antd

1. 安装:

(1)yarn add  antd

(2)yarn add babel-plugin-import --dev

2. 增加.babelrc文件:

{
  "presets": [
    "react-app"
  ],
  "plugins": [
    [
      "import",
      {
        "libraryName": "antd",
        "style": "css"
      }
    ]
  ]
}

// 旧版*************************************88

2. 打开webpack.config.dev.js文件(prod文件与之类似):

(找到如下代码段,并新增高亮处的代码)

// Process JS with Babel.
{
    test: /\.(js|jsx|mjs)$/,
    include: paths.appSrc,
    loader: require.resolve('babel-loader'),
    options: {
        plugins: [
            ['import', [{ libraryName: "antd", style: 'css' }]],
        ],
        // 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,
    },
},
 
// ****************************8
 
Step5:配置相对根路径
1、打开webpack.config.dev.js文件(prod文件与之类似):

(找到如下代码段,并新增高亮处的代码)

alias: {
 
  // Support React Native Web
  // https://www.smashingmagazine.com/2016/08/a-glimpse-into-the-future-with-react-native-for-web/
  'react-native': 'react-native-web',
  '@': path.resolve(__dirname, '../src'),
},
