webpack.optimize.CommonsChunkPlugin 報錯

webpack中文指南在代碼分離遇到了一個報錯：

webpack4 Error: webpack.optimize.CommonsChunkPlugin has been removed, please use config.optimization.splitChunks ins
因而百度了對應文章進行解決

optimization: {
        splitChunks: {
            cacheGroups: {
                commons: {
                    name: "commons",
                    chunks: "initial",
                    minChunks: 2
                }
            }
        }
    },
