使用webpack打包vue工程

记得去年十月份的时候，自己在研究webpack，当时只是知道大致的用法，写了一个简单的demo，现在，经过了7个月对公司产品架构的使用，以及对vue-cli的使用，在了解了实际应用中各种需求之后，我自己写了一套适合开发的vue-cli

为了满足业务需要我这里配置了四套环境，打包的时候可以自己根据不同的业务场景进行打包

首先看整体目录结构：

package.json里是各种依赖，build是四套webpack要读取的config，static是要复制到dist下的配置文件，四套环境的api都保存在这里。

index.html是一个单页程序的模版，也会打包到dist里，并且会把打包后的js，css，动态加载到index.html里

代码如下

package.json

  "name": "vue-demo",
  "version": "1.0.0",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",

dist文件夹

index.html模版

<!DOCTYPE html>

  <body>
    <div id="app">

index.html打包后
