# terminal 1
$ npm run dev

# 等价于 ✅
$ concurrently  "npm run dev:build" "npm run dev:auto"

# 等价于 ❌
$ npm run dev:build && npm run dev:auto

等价于 terminal 1 + terminal 2

# terminal 1
$ npm run dev:build

Linux terminal bash shell 中 && 与 & 区别

并行
串行

shell 中 && 和 & 的区别

1. & 是使用并行模式执行多个命令，同时并行执行左右边命令;

$ npm run dev:build & npm run dev:auto

{
  //...
  "scripts": {
    "dev": "npm run dev:build & npm run dev:auto",
    "dev:build": "tsc -w",
    "dev:auto": "nodemon node ./dist/app.js",
   },
   // ...
}

2. && 是使用串行模式执行多个命令，先执行左边命令，再执行右边命令 (先左后右，依次执行);

$ npm run dev:build && npm run dev:auto

{
  //...
  "scripts": {
    "dev": "npm run dev:build && npm run dev:auto",
    "dev:build": "tsc -w",
    "dev:auto": "nodemon node ./dist/app.js",
   },
   // ...
}
