我看过(不记得在哪里)一个package.json文件,其自定义键以下划线开头:

{
    "name": "application-name"
  , "version": "0.0.1"
  , "private": true
  , "dependencies": {
      "express": "2.4.7"
    , "jade": ">= 0.0.1"
  }
  , "_random": true
}

你被允许这样做吗？它仍然有效吗？如果允许,是否有关于规则的文档？

谢谢!

我在package.json中发现这些属性以下划线为前缀。它们是用来干什么的？为什么在属性上加下划线？

  "_from": "react-scripts@0.9.3",
  "_id": "react-scripts@0.9.3",
  "_inCache": true,
  "_location": "/react-scripts",
  "_nodeVersion": "6.0.0",
  "_npmOperationalInternal": {
    "host": "packages-18-east.internal.npmjs.com",
    "tmp": "tmp/react-scripts-0.9.3.tgz_1488303928068_0.6415497597772628"
  },
  "_npmUser": {
    "name": "gaearon",
    "email": "dan.abramov@gmail.com"
  },
