- 来自vue官方示例：https://github.com/vuejs/vue-loader-example
- 使用了vuejs和webpack，以及一系列webpack加载器，如vue-loader
- 依葫芦画瓢，试了试，有些具体分析还需要再学习学习，先简单记录下具体的做法，屡屡思绪。
- 添加github练习源码：https://github.com/dingyiming/learn-Js-vuejs/tree/master/demos/demo-vue-loader-example/demo1
目录结构
- demo/
+ package.json //npm配置文件
+ webpack.config.js //webpack配置
+ index.html //页面
- node_modules //npm加载的模块
- src //开发资源目录
- assets //一些资源
+ logo.png //图片资源
- components //vue组件
+ a.vue
+ b.vue
+ counter.vue
+ app.vue //布局文件
+ main.js //入口文件
初始化npm
1.生成npm配置文件 package.json
npm init
2.可以粘贴如下配置内容替换到package.json中，或者根据变动进行修改

"webpack": "^1.12.9",
"webpack-dev-server": "^1.14.0"
},
"dependencies": {
"vue": "^1.0.10"
}
}
3.下载node模块
npm install
- 其实我是一条条用
npm i xxx --save-dev敲的，没有在package.json里面的"devDependencies":{}手动添加内容，可以一个个装（也可以一起敲）如npm i webpack --save-dev,npm i vue --save--save-dev把依赖名和版本要求放在了"devDependencies":{}，--save放在了"dependencies":{}- 每敲一个下载完后可以看到
"devDependencies":{}依赖内容的添加
新建index.html用于展示最终页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Vue Webpack Example</title>
</head>
<body>
<app></app>
<script src="dist/build.js"></script>
</body>
</html>
新建webpack.config.js用于配置webpack
var webpack = require('webpack')
module.exports = {
entry: './src/main.js',
output: {
path: './dist',
publicPath: 'dist/',
filename: 'build.js'
},
module: {
loaders: [
{
test: /.vue$/,
loader: 'vue'
},
{
// edit this for additional asset file types
test: /.(png|jpg|gif)$/,
loader: 'file?name=[name].[ext]?[hash]'
}
]
},
// example: if you wish to apply custom babel options
// instead of using vue-loader's default:
babel: {
presets: ['es2015', 'stage-0'],
plugins: ['transform-runtime']
}
}
if (process.env.NODE_ENV === 'production') {
module.exports.plugins = [
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: '"production"'
}
}),
new webpack.optimize.UglifyJsPlugin({
compress: {
warnings: false
}
}),
new webpack.optimize.OccurenceOrderPlugin()
]
} else {
module.exports.devtool = '#source-map'
}
新建src目录用于存放开发文件
新建入口文件main.js
var Vue = require('vue')
var App = require('./app.vue')
new Vue({
el: 'body',
components: {
app: App
}
})
新建组件布局文件app.vue
组件布局将在这里设置，
.vue文件将由vue-loader进行加载，.vue内同时包含html、css、js源码，使组件的独立，组件之间可以尽可能地解耦，便于开发维护
<template lang="jade">
div
img(class="logo", src="./assets/logo.png")
h1 {{msg}}
comp-a
comp-b
counter
</template>
<script>
import CompA from './components/a.vue'
import CompB from './components/b.vue'
import Counter from './components/counter.vue'
export default {
data () {
return {
msg: 'Hello from vue-loader!'
}
},
components: {
CompA,
CompB,
Counter
}
}
</script>
<style lang="stylus">
font-stack = Helvetica, sans-serif
primary-color = #999
body
font 100% font-stack
color primary-color
.logo
width 40px
height 40px
</style>
新建components文件夹
用于开发具体的子组件，均以
.vue的后缀呈现
- a.vue
<style scoped>
.container {
border: 1px solid #00f;
}
.red {
color: #f00;
}
</style>
<template>
<div class="container">
<h2 class="red">{{msg}}</h2>
</div>
</template>
<script>
export default {
data () {
return {
msg: 'Hello from Component A!'
}
}
}
</script>
- b.vue
<style scoped>
.container {
border: 1px solid #f00;
}
h2 {
color: #393;
}
</style>
<template>
<div class="container">
<h2>Hello from Component B!</h2>
</div>
</template>
- counter.vue
<template>
<div>
<h1>I am a Counter Component. Edit me in dev mode.</h1>
<p>Current count: {{count}}</p>
</div>
</template>
<script>
export default {
data () {
return { count: 0 }
},
ready () {
this.handle = setInterval(() => {
this.count++
}, 1000)
},
destroyed () {
clearInterval(this.handle)
}
}
</script>
新建assets文件夹用于放一些资源
- 此项目下有一张图
打包运行查看
- 打包：
npm run build
- 运行
npm run dev
- 查看
浏览器中访问 localhost:8080
小结
经过通读官方文档和这个源码示例多少对vue有了更好的认识，不过还是得接下来多练习练习，加强熟悉度。
