UglifyJsPlugin摇树

Question

我正在尝试在我们的项目中配置树状摇动，但不知道如何启用它。据我了解，UglifyJsPlugin允许与webpack一起使用树状摇动，但是我是否需要其他配置？

UglifyJsPlugin conf：

new UglifyJsPlugin({
  "test": /\.js(\?.*)?$/i,
  "extractComments": false,
  "sourceMap": false,
  "cache": true,
  "parallel": true,
  "uglifyOptions": {
    "output": {
      "ascii_only": true,
      "comments": false,
      "webkit": true
    },
    "ecma": 5,
    "warnings": false,
    "ie8": false,
    "mangle": {
      "safari10": true
    },
    "compress": {
      "typeofs": false,
      "inline": 3,
      "pure_getters": true,
      "passes": 3
    }
  }
}),
