在React中使用less

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

{
  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
