1.安裝 nodejs
2.安裝 git
建議
本項目的定位是后臺集成方案引有，不太適合當(dāng)基礎(chǔ)模板來進(jìn)行二次開發(fā)。因為本項目集成了很多你可能用不到的功能，會造成不少的代碼冗余怠蹂。如果你的項目不關(guān)注這方面的問題抗愁，也可以直接基于它進(jìn)行二次開發(fā)蛮放。

安裝ES6語法插件

配置axios代理：

main.js中加入http
importhttpfrom'./utils/http'Vue.use(http)
調(diào)用接口：
index.vue ↓
<template><divclass="dashboard-container">歡迎</div></template><script>import { mapGetters } from 'vuex' export default { name: 'Dashboard', computed: { ...mapGetters([ 'name' ]) }, mounted(){ this.$http.get('/api/users/add').then(res => { console.log('this.panels', res) }) } }</script><stylelang="scss"scoped>.dashboard { &-container { margin: 30px; } &-text { font-size: 30px; line-height: 46px; } }</style>
6.全局安裝koa-generator,執(zhí)行下面命令
npm install -g koa-generator
7.構(gòu)建koa2項目代碼如下
koa2 projectName
構(gòu)建成功信息：
D:\project>koa2 projectName create:projectName create:projectName/package.json create:projectName/app.js create:projectName/publiccreate:projectName/public/images create:projectName/routes create:projectName/routes/index.js create:projectName/routes/users.js create:projectName/views create:projectName/views/index.pug create:projectName/views/layout.pug create:projectName/views/error.pug create:projectName/public/stylesheets create:projectName/public/stylesheets/style.css create:projectName/bin create:projectName/bin/www install dependencies:>cd projectName&&npm install run the app:>SETDEBUG=koa*&npm start projectName create:projectName/public/javascriptsD:\project>
初始化后臺項目插件弄诲，命令屬下:
cd projectName
初始化項目愚战，如果沒有安裝git會報錯.
npm install
項目試運(yùn)行
npm run dev
這里koa2模板提示信息做的并不好，沒有輸出測試地址齐遵，成功后出現(xiàn)如下界面代表成功了寂玲。
D:\project\projectName>npm run dev>projectName@0.1.0dev D:\project\projectName>nodemon bin/www[nodemon]1.19.4[nodemon]to restart at any time,enter `rs`[nodemon]watchingdir(s):*.*[nodemon]watching extensions:js,mjs,json[nodemon]starting `node bin/www`
在瀏覽器打開地址：
出現(xiàn)koa2的歡迎界面就代表成功了。
8.安裝本地mongodb或者在mongodb官網(wǎng)新建免費(fèi)的云端服務(wù)器梗摇。
安裝mongoose
npm install mongoose --save
在第7步建好的nodejs項目中根目錄創(chuàng)建db目錄
作者用的webstorm,可以根據(jù)自己需要下載編輯器
下面代碼中連接密碼需要修改成自己的
config.js ↓
module.exports={// dbs: 'mongodb://139.159.253.110:27017/test1'dbs:'mongodb+srv://xxwozixin:<需要修改>@cluster0-7d5kk.mongodb.net/test?retryWrites=true&w=majority'}
user.js ↓
constmongoose=require('mongoose')constfeld={name:String,age:Number,//人物標(biāo)簽labels:Number}//自動添加更新時間創(chuàng)建時間:letpersonSchema=newmongoose.Schema(feld,{timestamps:{createdAt:'created',updatedAt:'updated'}})module.exports=mongoose.model('User',personSchema)
修改根目錄app.js
app.js ↓
constKoa=require('koa')constapp=newKoa()constviews=require('koa-views')constjson=require('koa-json')constonerror=require('koa-onerror')constbodyparser=require('koa-bodyparser')constlogger=require('koa-logger')constindex=require('./routes/index')constusers=require('./routes/users')constmongoose=require('mongoose')constdbconfig=require('./db/config')mongoose.connect(dbconfig.dbs,{useNewUrlParser:true,useUnifiedTopology:true})constdb=mongoose.connectiondb.on('error',console.error.bind(console,'connection error:'));db.once('open',function(){console.log('mongoose 連接成功')});// error handleronerror(app)// middlewaresapp.use(bodyparser({enableTypes:['json','form','text']}))app.use(json())app.use(logger())app.use(require('koa-static')(__dirname+'/public'))app.use(views(__dirname+'/views',{extension:'pug'}))// loggerapp.use(async(ctx,next)=>{conststart=newDate()awaitnext()constms=newDate()-startconsole.log(`${ctx.method} ${ctx.url} - ${ms}ms`)})// routesapp.use(index.routes(),index.allowedMethods())app.use(users.routes(),users.allowedMethods())// error-handlingapp.on('error',(err,ctx)=>{console.error('server error',err,ctx)});module.exports=app// error handleronerror(app)// middlewaresapp.use(bodyparser({enableTypes:['json','form','text']}))app.use(json())app.use(logger())app.use(require('koa-static')(__dirname+'/public'))app.use(views(__dirname+'/views',{extension:'pug'}))// loggerapp.use(async(ctx,next)=>{conststart=newDate()awaitnext()constms=newDate()-startconsole.log(`${ctx.method} ${ctx.url} - ${ms}ms`)})// routesapp.use(index.routes(),index.allowedMethods())app.use(users.routes(),users.allowedMethods())// error-handlingapp.on('error',(err,ctx)=>{console.error('server error',err,ctx)});module.exports=app
user.js ↓
constrouter=require('koa-router')()constUser=require('../db/models/user')router.prefix('/users')router.get('/add',function(ctx,next){ctx.body='this is a users/bar response'})router.get('/',function(ctx,next){ctx.body='this is a users response!'})router.get('/bar',function(ctx,next){ctx.body='this is a users/bar response'})module.exports=router
重啟項目
關(guān)掉前面我們啟動的服務(wù)在運(yùn)行
npm run dev
如下結(jié)果代表成功連接數(shù)據(jù)庫
到這里前后端就連接通了拓哟，可以開始操作數(shù)據(jù)庫。
