1     new webpack.optimize.CommonsChunkPlugin({ 3       async: 'async-common', 4       minChunks: function (module, count) { 5         // any required modules inside node_modules are extracted to vendor 6         return ( 7           count >= 2 8         ) 9       }10     })

上述代码是将异步组件的公共组件打包到async-common中,但是build后通过 Webpack Bundle Analyzer 查看,发现并无效果.

正确配置如下:

new webpack.optimize.CommonsChunkPlugin({      names: Object.keys(utils.getEntries()),      async: 'async-common',      minChunks: function (module, count) {        // any required modules inside node_modules are extracted to vendor        return (          count >= 2        )      }    })

　　如上边代码,需要添加name或者names,此选项为entry的名字,因为我是多页面且多个入口,所以使用names, 通过Object.keys(utils.getEntries()) 获取我全部的入口名
