Question

使用CommonsChunkPlugin我目前将代码拆分为：

vendors.js
common.js
page-1.js
page-2-authenticated.js
page-3-authenticated.js

所以在page-1.html上我加载了以下脚本：

<script src="vendors.js" />
<script src="common.js" />
<script src="page-1.js" />

一切正常，page-1.js，page-2-authenticated.js和page-3-authenticated.js中的所有共享代码都捆绑在common.js中。

如您所见，我的应用程序要求用户登录page-2-authenticated.html和page-3-authenticated.html。但是，page-2-authenticated.js和page-3-authenticated.js中的共享代码也会捆绑到common.js中。 但我不想打扰未登录的用户，其代码仅在您登录时使用。

因此，对于page-2-authenticated.html ，我希望：

<script src="vendors.js" />
<script src="common.js" />
<script src="common-authenticated.js" /> // Shared code for authenticated users
<script src="page-2-authenticated.js" />

但是，当我在common-authenticated.js中导出测试变量并将其导入page-2-authenticated.js和page-3-authenticated.js时，此共享代码仍会捆绑到common.js中。 common-authenticated.js为空（只有一些webpackJsonp([12],[],[85]);）。

我有以下webpack 2配置：

entry: {
  vendors: ['react'],
  common: 'index.js',
  'common-authenticated': 'common-authenticated.js',
  'page-1': 'page-1.js',
  'page-2-authenticated': 'page-2-authenticated.js',
  'page-3-authenticated': 'page-3-authenticated.js'
},
plugins: [
  new webpack.optimize.CommonsChunkPlugin({
    // The order of this array matters
    names: ['common', 'vendors'],
    minChunks: 2
  })
]

问题：如何将特定代码捆绑到common-authenticated.js？有什么想法吗？

Answer 1

我能够通过以下配置解决它：

entry: {
  // Same as in topic start
},

plugins: [
  /*
   * Check the files used for pages on which you need to be logged in
   * and bundle the shared code of these files in a chunk named
   * 'common-authenticated' (its output will be in 'common-authenticated.js')
   */
  new webpack.optimize.CommonsChunkPlugin({
    name: 'common-authenticated',
    chunks: [
      'page-2-authenticated',
      'page-3-authenticated'
    ],
    minChunks: 2
  }),

  /*
   * Now check for shared code in the bundle defined above plus the files for
   * pages on which you do not need to be logged in. Bundle this shared code into
   * 'common.js'
   */
  new webpack.optimize.CommonsChunkPlugin({
    name: 'common',
    chunks: [
      'common-authenticated', // Name of the chunk defined above
      'page-1'
    ],
    minChunks: 2
  }),

  /*
   * I don't really now how this works. But it works :).
   * It generates the 'vendors.js'
   */
  new webpack.optimize.CommonsChunkPlugin({
    name: 'vendors',
    chunks: ['common', 'vendors'],
    minChunks: 2
  })
]

它给了我我想要的东西。 page-1.html中的脚本加载保持不变（我不需要common-authenticated.js）。 page-2-authenticated.html现在有：

<script src="vendors.js" />
<script src="common.js" />
<script src="common-authenticated.js" /> // Shared code for authenticated users
<script src="page-2-authenticated.js" />
