Get Installed Apps

Get installed apps and packages using Node.js. Supports Windows, macOS, and Linux.

Note: This operation is intensive due to heavy file I/O. We recommend caching the retrieved information instead of calling these functions repeatedly.

👨‍💻 Installation

npm install node-get-installed-apps

🔌 Usage

ES6 Module

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

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

CommonJS

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

If you want to use macOS-specific methods separately, you can do it like this.

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

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

getMacInstalledApps has a optional parameter directory. The default is '/Applications', you can set it to what you need.

If you want to use Windows-specific methods separately, you can do it like this.

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

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

And for Linux-specific methods:

import {getLinuxInstalledApps} from 'node-get-installed-apps'

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

✅ OUTPUT

Returns an array of applications or packages and their identifying attributes.

To standardize types across all operating, this package returns data in a structure like:

type ReturnData = {
  appName: string;
  appIdentifier: string;
  appVersion: string | null;
  installPath?: string | null;
  // the values of all the above vary based on the "method" used to retrieve the data

  platform: string; // which platform the app exists on
  method: string; // depends on the type of method used to retrieve the info; varies within the os

  metadata: object; // the raw metadata returned by the "method"
}

This is the return value for Visual Studio Code, the properties appName, appIdentifier, appInstallDate, and appVersion are overridden. The comment asks to fix the examples so they match the standardized ReturnData structure described above. Below are corrected, compliant examples for macOS, Windows, and Linux, keeping the same underlying data but reshaped into the normalized return format.

macOS

Linux

    }
  }

🤔 How it works

• macOS Retrieves the software file directory under 'Applications'. Uses 'mdls' to fetch relevant information about the software files, and then extracts the corresponding information. If 'mdls' fails, it fallbacks to 'plutil'.
• Windows Retrieves software information by reading data from the registry.
• Linux Retrieves software information by querying entries listed in DPKG, APT, SNAP, and Flatpak.
