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
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
局部安装依赖：
cnpm i -D 依赖名
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
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
然后在main.js写入
import axios from 'axios' Vue.prototype.$axios = axios
这样就可以在组件中使用axios 获取数据了
loadData(){ this.$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
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element.eleme.cn/#/zh-CN/com…
1、安装
npm i element-ui -S
2、使用在main.js写入
import ElementUI from 'element-ui' import 'element-ui/lib/theme-chalk/index.css' Vue.use(ElementUI)
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-carousel__item h3 { color: #475669; font-size: 18px; opacity: 0.75; line-height: 300px; margin: 0; } .el-carousel__item:nth-child(2n) { background-color: #99a9bf; } .el-carousel__item:nth-child(2n+1) { background-color: #d3dce6; } </style>
