      new CompressionPlugin({
        filename: "[path].gz[query]",
        algorithm: "gzip",
        test: productionGzipExtensions,
        // 只处理大于xx字节 的文件，默认：0
        threshold: 10240,
        // 示例：一个1024b大小的文件，压缩后大小为768b，minRatio : 0.75
        minRatio: 0.8, // 默认: 0.8
        // 是否删除源文件，默认: false
        deleteOriginalAssets: false
