我在一个非常古老的项目中使用 angular 1.5 和 express。现在我需要对其进行改造（而不是重建）。

我正在添加一些 webpack 优化并将其传输到客户端渲染 Angular 应用程序并将服务器代码与客户端代码分离。

我的最终目标是 - 使用 webpack 2 和 angular 1.5，使用具有最新代码标准的 ES6,6 功能来制作完整的工作流程。

我想使用 webpack 2 的特性，比如代码拆分和 tree shaking，这样我就可以按需加载所有模块。

为此，我创建了一个 webpack 配置。如果我{modules: false}从中删除它可以正常工作，.babelrc但是添加它对于摇树是必不可少的。

我的问题是，这几乎是我实现摇树所需要做的一切。但即使在这一切之后，我的 app.hash.js 构建后的文件也包含所有angular代码lodash。相反，它应该是仅适用module于Angular且仅适用于 lodash 的代码map

这是我的应用索引

import { module } from 'angular';
import { map } from 'lodash';

import '../style/app.css';

let app = () => {
  return {
    template: require('./app.html'),
    controller: 'AppCtrl',
    controllerAs: 'app'
  }
};

class AppCtrl {
  constructor() {
    this.appName = 'Fishry';

    const obj = {
      a: 'abc',
      d: 'efg'
    }
    _.map(obj, (value, key) => {
      console.log(value, key)
    })
  }
}

const MODULE_NAME = 'app';

module(MODULE_NAME, []).directive('app', app).controller('AppCtrl', AppCtrl);

export default MODULE_NAME;

这是我的 webpack conf

'use strict';

这是按.babelrc文件

{
  "presets": [

    "stage-0"
  ],
  "plugins": [
    "angularjs-annotate",
    "transform-runtime"
  ]
