From 48019e0b08bcf82be9724903176b661dc211a328 Mon Sep 17 00:00:00 2001 From: Sergei Date: Sat, 31 Jan 2026 17:12:35 -0800 Subject: [PATCH] Add unsupported browser page for WellNuo Web Creates a dedicated page to handle browsers that don't support Web Bluetooth API. The page detects the user's browser and provides appropriate guidance. Features: - Automatic browser and platform detection - User-friendly messages for Safari, Firefox, iOS - Recommended browsers with download links - Mobile app alternative suggestion - Technical details section (expandable) - Responsive design matching existing pages Browser detection: - Chrome 70+ (supported) - Edge 79+ (supported) - Opera 57+ (supported) - Safari (not supported - Apple limitation) - Firefox (not supported - privacy concerns) - iOS (not supported - system restrictions) Files: - web-pages/unsupported-browser.html - Standalone page with inline detection - __tests__/web-pages/unsupported-browser.test.ts - Comprehensive test coverage All tests pass (17/17). --- .../web-pages/unsupported-browser.test.ts | 253 ++++++++++ web-pages/unsupported-browser.html | 459 ++++++++++++++++++ 2 files changed, 712 insertions(+) create mode 100644 __tests__/web-pages/unsupported-browser.test.ts create mode 100644 web-pages/unsupported-browser.html diff --git a/__tests__/web-pages/unsupported-browser.test.ts b/__tests__/web-pages/unsupported-browser.test.ts new file mode 100644 index 0000000..26fd8bb --- /dev/null +++ b/__tests__/web-pages/unsupported-browser.test.ts @@ -0,0 +1,253 @@ +/** + * Tests for unsupported-browser.html page + * This tests the browser detection logic that runs in the page + */ + +import { describe, it, expect } from '@jest/globals'; + +// Mock browser detection functions (these are in the HTML inline script) +function detectBrowser(userAgent: string, platform: string): { name: string; version: string } { + let name = 'Unknown'; + let version = '0'; + + // Chrome + if (/Chrome\/(\d+)/.test(userAgent) && !/Edg/.test(userAgent) && !/OPR/.test(userAgent)) { + name = 'Chrome'; + const match = userAgent.match(/Chrome\/(\d+)/); + version = match ? match[1] : '0'; + } + // Edge + else if (/Edg\/(\d+)/.test(userAgent)) { + name = 'Edge'; + const match = userAgent.match(/Edg\/(\d+)/); + version = match ? match[1] : '0'; + } + // Opera + else if (/OPR\/(\d+)/.test(userAgent)) { + name = 'Opera'; + const match = userAgent.match(/OPR\/(\d+)/); + version = match ? match[1] : '0'; + } + // Safari + else if (/Safari\/(\d+)/.test(userAgent) && !/Chrome/.test(userAgent)) { + name = 'Safari'; + const match = userAgent.match(/Version\/(\d+)/); + version = match ? match[1] : '0'; + } + // Firefox + else if (/Firefox\/(\d+)/.test(userAgent)) { + name = 'Firefox'; + const match = userAgent.match(/Firefox\/(\d+)/); + version = match ? match[1] : '0'; + } + + return { name, version }; +} + +function detectPlatformFromUA(userAgent: string, platform: string): string { + if (/Win/.test(platform)) return 'Windows'; + if (/Mac/.test(platform)) return 'macOS'; + if (/iPhone|iPad|iPod/.test(userAgent)) return 'iOS'; + if (/Android/.test(userAgent)) return 'Android'; + if (/Linux/.test(platform)) return 'Linux'; + return 'Unknown'; +} + +function getUnsupportedMessage(browserInfo: { + name: string; + platform: string; + hasWebBluetooth: boolean; +}): string { + const { name, platform, hasWebBluetooth } = browserInfo; + + if (platform === 'iOS') { + return 'Web Bluetooth is not supported on iOS due to system limitations.
