koa和vue项目前后端联动启动

最近学习前后端的全栈项目，头大的要命，慢慢发现，自己越用功想研究一门技术，越发现不懂的慢慢越多，真是有点打击信心。

好在，今天终于把前后端的基础框架搭起来了，后续文章分享学习经验。

今天分享是前后端联动启动

首先安装concurrently

然后安装vue项目

vue -V 我现在已经装上3.0版本了。

vue create client

按照提示把vue-router vuex eslint sass等安装好，自动安装依赖包，稍等一会，装好前端vue项目后，我们启动一下，8080端口跑起来就ctrl+c退出前端

接下来，修改前端vue的package.json

{
  "name": "client",
  "version": "0.1.0",
  "private": true,
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "start": "npm run serve"
  },
  "dependencies": {
    "vue": "^2.5.17",
    "vue-router": "^3.0.1",
    "vuex": "^3.0.1"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "^3.1.1",
    "@vue/cli-plugin-eslint": "^3.1.1",
    "@vue/cli-service": "^3.1.1",
    "@vue/eslint-config-standard": "^4.0.0",
    "babel-eslint": "^10.0.1",
    "eslint": "^5.8.0",
    "eslint-plugin-vue": "^5.0.0-0",
    "node-sass": "^4.9.0",
    "sass-loader": "^7.0.1",
    "vue-template-compiler": "^2.5.17"
  },
  "eslintConfig": {
    "root": true,
    "env": {
      "node": true
    },
    "extends": [
      "plugin:vue/essential",
      "@vue/standard"
    ],
    "rules": {},
    "parserOptions": {
      "parser": "babel-eslint"
    }
  },
  "postcss": {
    "plugins": {
      "autoprefixer": {}
    }
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not ie <= 8"
  ]
}

注意，主要增加了start命令 npm run serve

接下来，修改后端koa的配置

也是同样打开package.json

{
  "name": "resfulapi",
  "version": "1.0.0",
  "description": "resfulAPI",
  "main": "app.js",
  "scripts": {
    "client-install": "npm install --prefix client",
    "client": "npm start --prefix client",
    "start": "node app.js",
    "server": "nodemon app.js",
    "lint": "eslint --fix --ext .js,.vue",
    "dev": "concurrently \"npm run server\" \"npm run client\""
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "art-template": "^4.13.2",
    "axios": "^0.18.0",
    "babel-eslint": "^10.0.1",
    "bcrypt": "^3.0.2",
    "concurrently": "^4.1.0",
    "eslint": "^4.15.0",
    "eslint-config-airbnb-base": "^13.1.0",
    "eslint-config-standard": "^12.0.0",
    "eslint-plugin-html": "^5.0.0",
    "eslint-plugin-import": "^2.7.0",
    "eslint-plugin-node": "^5.2.0",
    "eslint-plugin-promise": "^4.0.1",
    "eslint-plugin-standard": "^4.0.0",
    "eslint-plugin-vue": "^4.7.1",
    "gravatar": "^1.8.0",
    "jsonwebtoken": "^8.4.0",
    "koa": "^2.6.2",
    "koa-art-template": "^1.1.1",
    "koa-bodyparser": "^4.2.1",
    "koa-json": "^2.0.2",
    "koa-jwt": "^3.5.1",
    "koa-passport": "^4.1.1",
    "koa-router": "^7.4.0",
    "koa-static": "^5.0.0",
    "mongoose": "^5.3.15",
    "passport": "^0.4.0",
    "passport-jwt": "^4.0.0",
    "passport-local": "^1.0.0",
    "vue": "^2.5.2",
    "vue-router": "^3.0.1"
  }
}

注意，也是修改了启动命令，主要是这三条

"client-install": "npm install --prefix client"  联动启动前，先安装client目录下的vue项目的npm包
"client": "npm start --prefix client", 联动启动前先启动client目录下npm start ，看package，json里，我们已经配置了npm start
"dev": "concurrently \"npm run server\" \"npm run client\""
联动启动前后端项目

这样，我们用concurrently来联动启动我们的前后端项目，npm run dev，快乐的启动吧！

最近脑子感觉不够用，一个人默默的啃代码，写下来，防止以后再找资料
