react less环境配置

书池 2022-06-02 我要评论

1.安装less

npm install less-loader less --save-dev

2.找到node_modules文件夹里react-scripts/config/webpack.config.js

在这个下面添加less相关配置

const lessRegex = /\.less$/;
const lessModuleRegex = /\.module\.less$/;

3.然后往下翻代码到下图

在这段代码下面加

{
              test: lessRegex,
              exclude: sassModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 2,
                  sourceMap: isEnvProduction && shouldUseSourceMap,
                },
                'less-loader'
              ),
              sideEffects: true,
            },
            {
              test: lessModuleRegex,
              use: getStyleLoaders(
                {
                  importLoaders: 2,
                  sourceMap: isEnvProduction && shouldUseSourceMap,
                  modules: true,
                  getLocalIdent: getCSSModuleLocalIdent,
                },
                'less-loader'
              ),
            },
