Progressive Web Apps

PWA configuration that enables install-to-home-screen on Android Chrome and iOS Safari — with a proper app manifest, icons, splash screens and install prompt. Users get the app on their home screen and can launch it full-screen without a browser chrome.

• Web App Manifest: name, icons, theme colour, display mode
• Install prompt implementation (beforeinstallprompt on Android)
• iOS Safari install instruction flow (manual add-to-homescreen)
• Splash screen and launch image for iOS and Android
• Full-screen standalone display mode
• App shortcut definition for Android long-press actions
• Icon set generation: all required sizes for iOS and Android
• Installation analytics: track install prompt shown vs. accepted

Service worker implementation that caches the application shell and key content for offline use — so the app loads even without a network connection, shows cached data when offline and synchronises changes when connectivity returns.

• Service worker registration and lifecycle management
• App shell caching: HTML, CSS, JS and core assets
• Content caching strategies: cache-first, network-first, stale-while-revalidate
• Background sync for actions taken while offline
• Cache invalidation on new app version deployment
• Offline fallback page for uncached content
• Workbox integration for service worker management
• Cache storage quota management and cleanup

Web push notification implementation for PWAs — sending notifications to users even when the browser is closed, using the Web Push API with proper permission flows, notification management and deep link routing on notification tap.

• Web Push API implementation with VAPID keys
• Permission request with clear value proposition explanation
• Notification categories and preference management
• Notification payload: title, body, icon, badge, actions
• Deep link routing on notification click
• Notification click analytics
• Subscription management: store, refresh, unsubscribe
• Server-side push using web-push library or push service

Mobile-first UX design and implementation that makes the PWA feel like a native app — with touch-friendly tap targets, smooth transitions, bottom navigation for thumb reach, proper keyboard handling and iOS safe area support for notch and home indicator.

• Touch-friendly minimum 44px tap targets throughout
• Bottom tab navigation for one-handed use
• Swipe gestures for navigation and actions
• Pull-to-refresh for list content
• iOS safe area inset handling: notch and home indicator
• Keyboard-aware layout: inputs stay visible when keyboard opens
• Native-feeling page transitions and animations
• Loading skeleton screens instead of spinner-only states

PWA performance optimisation targeting high Core Web Vitals scores — Largest Contentful Paint, First Input Delay and Cumulative Layout Shift — ensuring the app loads quickly on mobile connections and passes Google's page experience signals.

• LCP optimisation: preload critical images and fonts
• FID/INP optimisation: break long tasks, defer non-critical JS
• CLS prevention: reserve space for dynamic content
• JavaScript code splitting and lazy loading
• Image optimisation: WebP, AVIF with fallback, responsive images
• Critical CSS inlining and non-critical CSS deferral
• HTTP/2 server push for critical resources
• Core Web Vitals monitoring in production with alerting

Analytics implementation for PWAs that tracks both web and installed-app usage — understanding how users find, install and use the application, measuring the difference in engagement between installed and browser-only users.

• GA4 or Plausible integration for PWA usage tracking
• Install rate tracking: visits to install ratio
• Display mode detection: is user in standalone or browser mode
• Offline usage events: sessions and actions taken offline
• Push notification opt-in rate and notification engagement
• User journey analysis from web to install
• Retention comparison: installed vs. browser-only user cohorts
• Session quality metrics: depth, duration, return rate
