npm与package.json

更新npm到最新版本

• npm install -g npm

四个npm自带的简写指令

• npm start => npm run start
• npm stop => npm run stop
• npm test => npm run test
• npm restart => npm run stop & npm run restart & npm run start

package.json执行多条指令

通过&&,使package.json执行完前一条指令且不报错时,执行下一条指令

{
  "name": "V3",
  "version": "0.0.0",
  "private": true,
  "scripts": {
    "start": "cd angular && npm start",
    "product": "cd angular && npm run product"
  }
}
