{
                test: /\.scss$/,
                use: isProd
                    ? ExtractTextPlugin.extract({
                        fallback: 'vue-style-loader',
                        use: [
                            {
                                loader: 'css-loader',
                                options: { minimize: true }
                            },
                            'sass-loader'
                        ],
                    })
                    : ['vue-style-loader', 'css-loader', 'sass-loader']
            }
