cookingk配置项中的chunk:true含义

Posted 2020-08-12

学习cooking，查看中文文档，发现有个配置chunk: true, 不明白具体含义，于是根据注释，找到了相关代码，

即chunk: true等同于以下代码：

var webpackConfig = merge(baseWebpackConfig, {
  //...
  plugins: [
    // split vendor js into its own file
    new webpack.optimize.CommonsChunkPlugin({
      name: ‘vendor‘,
      minChunks: function (module, count) {
        // any required modules inside node_modules are extracted to vendor
        return (
          module.resource &&
          /\.js$/.test(module.resource) &&
          module.resource.indexOf(
            path.join(__dirname, ‘../node_modules‘)
          ) === 0
        )
      }
    }),
    // extract webpack runtime and module manifest to its own file in order to
    // prevent vendor hash from being updated whenever app bundle is updated
    new webpack.optimize.CommonsChunkPlugin({
      name: ‘manifest‘,
      chunks: [‘vendor‘]
    })
  ]
})

也就是两个webpack插件：CommonsChunkPlugin，CommonsChunkPlugin及默认配置
