multi-platform-checker

A utility to detect running platform (browser, Node.js, mini programs) and operating systems (Android, iOS, HarmonyOS) with version detection.

Installation

npm install multi-platform-checker

Usage

const platformChecker = require('multi-platform-checker');

// Get all environment info const envInfo = platformChecker.detect(); console.log('Environment info:', envInfo);

// Check specific environment if (platformChecker.isBrowser()) { console.log('Running in browser'); }

// Check operating systems if (platformChecker.isAndroid()) { console.log('Running on Android'); console.log('Android version:', platformChecker.getOSVersion()); }

if (platformChecker.isIOS()) { console.log('Running on iOS'); console.log('iOS version:', platformChecker.getOSVersion()); }

if (platformChecker.isHarmonyOS()) { console.log('Running on HarmonyOS'); console.log('HarmonyOS version:', platformChecker.getOSVersion()); }

// Check specific versions if (platformChecker.isIOSVersion('14.0')) { console.log('iOS version is 14.0 or higher'); }

if (platformChecker.isAndroidVersion('10.0')) { console.log('Android version is 10.0 or higher'); }

// Compare versions manually const versionComparison = platformChecker.compareVersions( platformChecker.getOSVersion(), '9.0' ); switch (versionComparison) { case 1: console.log('Current OS version is higher than 9.0'); break; case 0: console.log('Current OS version is exactly 9.0'); break; case -1: console.log('Current OS version is lower than 9.0'); break; }

API

Environment Detection

• detect() - Returns full environment information object
• isBrowser() - Returns true if running in a browser
• isNode() - Returns true if running in Node.js
• isWechatMiniProgram() - Returns true if running in WeChat Mini Program
• isAlipayMiniProgram() - Returns true if running in Alipay Mini Program

OS Detection

• isAndroid() - Returns true if running on Android
• isIOS() - Returns true if running on iOS
• isHarmonyOS() - Returns true if running on HarmonyOS
• getOSVersion() - Returns the OS version as a string (e.g. "14.5.1")
• getParsedOSVersion() - Returns the OS version as an array of numbers (e.g. [14, 5, 1])
• getUserAgent() - Returns the user agent string

Version Comparison

• compareVersions(version1, version2) - Compares two versions, returns 1 if version1 > version2, 0 if equal, -1 if version1 < version2
• isAndroidVersion(version) - Returns true if running on Android with version >= specified version
• isIOSVersion(version) - Returns true if running on iOS with version >= specified version
• isHarmonyOSVersion(version) - Returns true if running on HarmonyOS with version >= specified version
