Divide css into those that need to be packaged and those that do not need to be packaged. Generally, the css source files that need to be packaged are preprocessed files, such as files ending with .less, .scss, .styl, etc. You can package these parts The file is configured with webpack, and files with the .css suffix are not processed by css module.

Example:

      {
        test: /\.pcss$/,
        use: [
          'style-loader',
          {
            loader: 'css-loader',
            options: {
              camelCase: true,
              importLoaders: 1,
              localIdentName: '[path][name]---[local]---[hash:base64:5]',
              modules: true,
            },
          },
          {
            loader: 'postcss-loader',
            options: {
              plugins: () => [
                require('postcss-import')({
                  path: path.join(baseDir, './src/style'),
                }),
                require('postcss-cssnext'),
                require('postcss-nested'),
                require('postcss-functions')({
                  functions: {
                    // any funcs you wanna
                  },
                }),
              ],
            },
          },
        ],
      },
      {
        test: /\.css$/,
        use: ExtractTextPlugin.extract({
          fallback: 'style-loader',
          use: [
            'css-loader',
          ],
        }),
      },
