react装less
- npm install less@3.9.0
- npm install less-loader@4.1.0
- 下载完成后执行：npm run eject；暴露config等一些配置文件
-
const sassRegex = /\.(scss|sass)$/; const sassModuleRegex = /\.module\.(scss|sass)$/; 在下面新增两条 const lessRegex = /\.less$/; const lessModuleRegex = /\.module\.less$/; { test: sassRegex, exclude: sassModuleRegex, use: getStyleLoaders( { importLoaders: 2, sourceMap: isEnvProduction && shouldUseSourceMap, }, 'sass-loader' ), sideEffects: true, }, //对应的增加一条 { test: lessRegex, exclude: sassModuleRegex, use: getStyleLoaders( { importLoaders: 2, sourceMap: isEnvProduction && shouldUseSourceMap, }, 'less-loader' ), sideEffects: true, }, { test: sassModuleRegex, use: getStyleLoaders( { importLoaders: 2, sourceMap: isEnvProduction && shouldUseSourceMap, modules: true, getLocalIdent: getCSSModuleLocalIdent, }, 'sass-loader' ), }, //对应的增加一条 { test: lessModuleRegex, use: getStyleLoaders( { importLoaders: 2, sourceMap: isEnvProduction && shouldUseSourceMap, modules: true, getLocalIdent: getCSSModuleLocalIdent, }, 'less-loader' ), },
