一、搭建cli
1.事先安装好cnpm(淘宝镜像)
npm install -g cnpm --registry=https://registry.npm.taobao.org
1
2.cnpm install -g vue-cli
全局安装vue脚手架工具。（下载一次就好）
3.vue init webpack your_project_name
创建一个脚手架项目（每次创建需要）
eg:这时在命令行中有需要你填的信息{
你的项目名；
你的项目描述；
还有你想是否下载的插件（y/n）；
}
4.使用 npm run dev来运行项目
就这样，一个简单的vue开发项目模板就这样下载完成了。
eg：
i 是install 的简写。
全局安装依赖：
cnpm i 依赖名
1
局部安装依赖：
cnpm i -D 依赖名
1
二、vue-router
一般事先安装模板时，已经安装上了。
可以查看package.json中。
如果没有安装
cnpm i -D vue-router
1
安装好之后，在src目录中会生成一个router目录，里面放着index.js，
一般有两种配置
第一种：
import Vue from 'vue';
import Router from 'vue-router';
Vue.use(Router);
export default new Router({
routes: [
// 一进入就显示页面
{
path: '/',
redirect: '/index'
},
{
path: '/',
component: pather => require(['../components/common/bodys.vue'], pather),
meta: { title: '主体' },
children:[
{
path: '/index',
component: pather => require(['../components/page/index.vue'], pather),
meta: { title: '系统首页' }
},
{
path: '/biaoge',
component: pather => require(['../components/page/biaoge.vue'], pather),
meta: { title: '基础表格' }
},
{
path: '/Tab',
component: pather => require(['../components/page/Tab.vue'], pather),
meta: { title: 'tab选项卡' }
},
{
path: '/jibenbiaodan',
component: pather => require(['../components/page/jibenbiaodan.vue'], pather),
meta: { title: '基本表单' }
},
{
path: '/fuwenben',
component: pather => require(['../components/page/fuwenben.vue'], pather),
meta: { title: '富文本编辑器' }
},
{
path: '/bianjiqi',
component: pather => require(['../components/page/bianjiqi.vue'], pather),
meta: { title: 'markdown编辑器' }
},
{
path: '/shangchuan',
component: pather => require(['../components/page/shangchuan.vue'], pather),
meta: { title: '文件上传' }
},
{
path: '/scharts',
component: pather => require(['../components/page/scharts.vue'], pather),
meta: { title: 'schart图表' }
},
{
path: '/tuozhuai',
component: pather => require(['../components/page/tuozhuai.vue'], pather),
meta: { title: '拖拽列表' }
},
{
path: '/quanxianceshi',
component: pather => require(['../components/page/quanxianceshi.vue'], pather),
meta: { title: '权限测试', permission: true }
}
]
},
{
path: '/login',
component: pather => require(['../components/page/login.vue'], pather)
},
{
path: '/cuowu404',
component: pather => require(['../components/page/cuowu404.vue'], pather)
},
{
path: '/cuowu403',
component: pather => require(['../components/page/cuowu403.vue'], pather)
},
{
path: '*',
redirect: '/404'
}
],
// 去掉#号
mode:"history"
})
第二种：
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
Vue.use(Router)
export default new Router({
routes: [
{
path: '/',
name: 'HelloWorld',
component: HelloWorld
}
]
})
三、axios
先安装
cnpm i -D axios
1
然后在main.js写入
import axios from 'axios'
Vue.prototype.$axios = axios
1
2
3
这样就可以在组件中使用axios 获取数据了
loadData(){
this.$axios.get(['https://free-api.heweather.com/v5/weather?city=qingdao&key=1b47b16e4aa545eaa55a66f859ac0089'])
.then((response) => {
// success
console.log(response.data);
})
.catch((error) => {
//error
console.log(error);
})
},
四、vuex
1、安装
cnpm i -D vuex
1
2、然后需要手动创建一个文件夹store在src目录当中，
接着在store文件夹中创建store.js
例：
import Vue from 'vue'
import Vuex from 'vuex'
Vue.use(Vuex)
export default new Vuex.Store({
state: {
count: 0
},
mutations: {
increment: state => state.count++,
decrement: state => state.count--,
}
})

3、然后在main.js引入注册
import Vuex from 'vuex'
import store from './store/store'
Vue.use(Vuex)
new Vue({
el: '#app',
router,
store,
components: { App },
template: '<App/>'
})
比如在headers.vue使用vuex
<template>
<div class="headers">
<p>{{count}}</p>
<button @click="increment">+</button>
<button @click="decrement">-</button>
</div>
</template>
<script>
import { mapState } from 'vuex'
export default {
name: 'headers',
data () {
return {
msg: 'Welcome to Your Vue.js App'
}
},
methods: {
increment(){
this.$store.commit('increment')
},
decrement(){
this.$store.commit('decrement')
}
},
computed:{
count(){
return this.$store.state.count
},
}
}
</script>
<style scoped lang="scss" >
</style>
五、sass
1、需要安装sass
(1)安装node-sass
(2)安装sass-loader
(3)安装style-loader 有些人安装的是 vue-style-loader 其实是一样的！
cnpm install node-sass --save-dev
cnpm install sass-loader --save-dev
cnpm install style-loader --save-dev

2、接着需要更改build文件夹下面的webpack.base.config.js
'use strict'
const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
function resolve (dir) {
return path.join(dirname, '..', dir)
}
module.exports = {
context: path.resolve(dirname, '../'),
entry: {
app: './src/main.js'
},
output: {
path: config.build.assetsRoot,
filename: '[name].js',
publicPath: process.env.NODE_ENV === 'production'
? config.build.assetsPublicPath
: config.dev.assetsPublicPath
},
resolve: {
extensions: ['.js', '.vue', '.json'],
alias: {
'vue$': 'vue/dist/vue.esm.js',
'@': resolve('src'),
}
},
module: {
rules: [
{
test: /.vue$/,
loader: 'vue-loader',
options: vueLoaderConfig
},
{
test: /.js$/,
loader: 'babel-loader',
include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
},
{
test: /.(png|jpe?g|gif|svg)(\?.)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('img/[name].[hash:7].[ext]')
}
},
{
test: /.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('media/[name].[hash:7].[ext]')
}
},
{
test: /.(woff2?|eot|ttf|otf)(\?.*)?$/,
loader: 'url-loader',
options: {
limit: 10000,
name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
}
},
{ //从这一段上面是默认的！不用改！下面是没有的需要你手动添加，相当于是编译识别sass!
test: /.scss$/,
loaders: ["style", "css", "sass"]
}
]
},
node: {
// prevent webpack from injecting useless setImmediate polyfill because Vue
// source contains it (although only uses it if it's native).
setImmediate: false,
// prevent webpack from injecting mocks to Node native modules
// that does not make sense for the client
dgram: 'empty',
fs: 'empty',
net: 'empty',
tls: 'empty',
child_process: 'empty'
}
}
3、在你需要使用sass的地方写入即可
<style lang="scss" scoped="" type="text/css">
$primary-color: #333;
body {
color: $primary-color;
}
</style>
六、vue UI库
这里已著名的Element组件库为例
https://element.eleme.cn/#/zh-CN/component/carousel
1、安装
npm i element-ui -S
1
2、使用
在main.js写入
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
Vue.use(ElementUI)
1
2
3
4
3、然后在组件使用就可以了
例：轮播图
<template>
<el-carousel indicator-position="outside">
<el-carousel-item v-for="item in 4" :key="item">
<h3>{{ item }}</h3>
</el-carousel-item>
</el-carousel>
</template>
<style>
.el-carouselitem h3 {
color: #475669;
font-size: 18px;
opacity: 0.75;
line-height: 300px;
margin: 0;
}
.el-carouselitem:nth-child(2n) {
background-color: #99a9bf;
}
.el-carousel__item:nth-child(2n+1) {
background-color: #d3dce6;
}
</style>
