react 支持less 和antd和更换antd主题

less

1. npm install less --save
2. npm install less-loader --save
   完成之后在packge.json里的dependencies中有
   
3. 暴露webpack配置 npm run eject 多出几个文件
   
4. 配置less
   const lessRegex = /\.less$/;
const lessModuleRegex = /\.module\.less$/;
   将上两句话添加到 config->webpack.config.js
   

    {
              test: lessRegex,
              exclude: lessModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 2,
                  sourceMap: isEnvProduction && shouldUseSourceMap,
                },
                'less-loader'
              ),
              // Don't consider CSS imports dead code even if the
              // containing package claims to have no side effects.
              // Remove this when webpack adds a warning or an error for this.
              // See https://github.com/webpack/webpack/issues/6571
              sideEffects: true,
            },
            // Adds support for CSS Modules, but using SASS
            // using the extension .module.scss or .module.sass
            {
              test: lessModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 2,
                  sourceMap: isEnvProduction && shouldUseSourceMap,
                  modules: true,
                  getLocalIdent: getCSSModuleLocalIdent,
                },
                'less-loader'
              ),
            },

测试：将App.css重命名为App.less 不报错

####antd

1. npm install babel-plugin-import --save 同样会在依赖中找到

                  {
                     "libraryName": "antd", 
                     "libraryDirectory": "es", 
                     "style": "css" 
                   }
                 ] ,

将上述代码贴到如图位置

重启react 项目

此时可以不引入antd.css同样可以运行项目

antd更换主题

1.上诉同样位置引更改配置是时需要将"style":"css更换为"style:"true如下图

2.将如下代码贴到下图位置

 {
              test: /\.less$/,
              //include: paths.appSrc,
              use: [{
                  loader: "style-loader" // creates style nodes from JS strings
              }, {
                  loader: "css-loader" // translates CSS into CommonJS
              }, {
                  loader: "less-loader",// compiles Less to CSS
                  options: {
                      sourceMap: true,
                      modifyVars: {
                          'primary-color': '#f9c700',
                          'link-color': '#1DA57A',
                          'border-radius-base': '2px',
                      },
                      javascriptEnabled: true,
                  }
              }]
          },
