platform-utils

Helper functions for working with platform names in the Node.js vernacular (darwin, win32, linux). Works in Node.js and browsers.

Plays well with the Node.js core modules os.platform() and process.platform.

Installation

npm install platform-utils --save

Usage

This module exports an object with utility functions.

const {
  getPlatformFromFilename,
  getPlatformFromUserAgent,
  getPlatformLabel
} = require('platform-utils')

API

getPlatformFromFilename(filename)

• filename String - e.g. dist/my-cool-app.dmg

Returns String darwin, win32, linux, or null.
Here's the gist of how the detection works:

if (ext === 'exe') return 'win32'
if (ext === 'zip' && parts.includes('win32')) return 'win32'
if (ext === 'zip' && parts.includes('windows')) return 'win32'
if (ext === 'zip' && parts.includes('win')) return 'win32'
if (ext === 'zip' && parts.includes('ia32')) return 'win32'

if (ext === 'dmg') return 'darwin'
if (ext === 'pkg') return 'darwin'
if (ext === 'zip' && parts.includes('osx')) return 'darwin'
if (ext === 'zip' && parts.includes('mac')) return 'darwin'
if (ext === 'zip' && parts.includes('macos')) return 'darwin'
if (ext === 'zip' && parts.includes('mas')) return 'darwin'
if (ext === 'zip' && parts.includes('darwin')) return 'darwin'

if (ext === 'rpm') return 'linux'
if (ext === 'deb') return 'linux'
if (ext === 'appimage') return 'linux'
if (ext === 'zip' && parts.includes('linux')) return 'linux'

getPlatformFromUserAgent([agent])

• agent String (optional) - Can be omitted when used in the browser, where

navigator.userAgent will be used automatically.
Returns String darwin, win32, linux, or null.

getPlatformLabel(platform)

• platform String - Can be darwin, win32, or linux.

Returns String macOS, Windows, Linux, or null.
