//package.json
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "app": "./server/app.js"
  },
  直接这样是不行的，因为没有yarn app.js这种执行语句，需要改为：
  "scripts": {
    "serve": "vue-cli-service serve",
    "build": "vue-cli-service build",
    "lint": "vue-cli-service lint",
    "app": "node ./server/app.js" 
  },

In the statement before execution plus the normal node can perform
the equivalent of

node app.js
