通过Node.js 获取电脑安装的软件，支持Windows和Mac两个平台。

👨‍💻 安装

npm install get-installed-apps

🔌 用法

ES6 Module

import {getInstalledApps} from 'get-installed-apps'

getInstalledApps().then(apps => {
  console.log(apps)
})

CommonJS

const {getInstalledApps} = require('get-installed-apps')
getInstalledApps().then(apps => {
  console.log(apps)
})

如果你只想在mac平台上使用，可以这么做：

import {getMacInstalledApps} from 'get-installed-apps'

getMacInstalledApps().then(apps => {
  console.log(apps)
})

如果你只想在windows平台上使用，可以这么做：

import {getWinInstalledApps} from 'get-installed-apps'

getWinInstalledApps().then(apps => {
  console.log(apps)
})

✅ 输出

返回一个数组。

下面是一个vscode的软件信息返回值， appName, appIdentifier, appInstallDate, appVersion这四个值是新的属性，主要保证双端统一。

🤔 原理

• macOS 通过获取Applications文件夹下所有的文件，然后通过mdls获取文件的属性，然后解析相应的信息，形成结构的app信息的对象。
• Windows 主要是读取注册表的数据，然后解析相应的信息，形成结构的app信息的对象
