首先看了index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>vue-test</title>
</head>
<body>
<div id="app"></div>
<!-- built files will be auto injected -->
</body>
</html>
注意<div id="app"></div>。接着关注到main.js，定义了#app对index.html中的app进行替换。同时，定义一个app模板和一个app组件，并对进行引入。
// main.js代码
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
/* eslint-disable no-new */
c({
el: '#app',
template: '<App/>',
components: { App }
})
app.vue源码如下，定义了 app模板布局以及样式，同时又引入hello组件。
<template>
<div id="app">
<hello></hello>
</div>
</template>
<script>
import Hello from './components/Hello'
export default {
name: 'app',
components: {
Hello
}
}
</script>
<style>
#app {
font-family: 'Avenir', Helvetica, Arial, sans-serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
text-align: center;
color: #2c3e50;
margin-top: 60px;
}
</style>
hello.vue源码，定义了hello布局、内容以及样式。
<template>
<div class="hello">
<h1>{{ msg }}</h1>

总结，目前对vue的理解是：html是view视图层，.vue负责model的管理，每一个vue将model和view进行绑定结合。
