问题：
（目前发现所有用到ajax函数的页面都含有resource.js代码和vue-resource.js）
1、怎样抽离vue-resource.js?[外部共用插件]
2、怎样抽离resource.js？[项目内部封装的工具函数]
3、怎样抽离公共样式文件？[共用的样式组件库和页面样式代码]
4、vue.js抽离在哪个文件了？

Answer 1

使用 CommonsChunkPlugin，具体用法见 CommonsChunkPlugin 的文档

options.minChunks (number|Infinity|function(module, count) -> boolean): The minimum number of chunks which need to contain a module before it's moved into the commons chunk. The number must be greater than or equal 2 and lower than or equal to the number of chunks. Passing Infinity just creates the commons chunk, but moves no modules into it. By providing a function you can add custom logic. (Defaults to the number of chunks)

看得懂吗？看不懂就算了，我没有义务牺牲自己的时间来替你省学英语的时间！
