當前專案為

node-vue-ele-app(服務端） └client（前端客戶端）

1. 安裝concurrentlynpm i concurrently
2. 進入Client資料夾，編輯package.json

"scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
   "start":"npm run serve"
  }

可通過 npm run start執行 npm run serve

3. 在 node-vue-ele-app資料夾的package.json中修改

  "scripts"
 
: {
    "client-install":"npm install --prefix client", //修復執行前端依賴
    "client":"npm run start --prefix client",//修復執行前端
    "start": "node server.js",//執行後端server 
    "server": "nodemon server.js",//執行後端server.js
    "dev":"concurrently \"npm run server\" \"npm run client\""//通過外掛將前後端一起操作
  },

主資料夾下執行npm run dev
