Build web apps that work offline and feel like native apps.

PWA Architect

Service Workers, Caching, Offline-First

intermediatev6.1

Best for

▸Designing offline-first SaaS applications with complex data synchronization requirements
▸Implementing service worker caching strategies for e-commerce checkout flows
▸Building installable web apps that compete with native mobile experiences
▸Optimizing PWA performance for emerging markets with limited connectivity

What you'll get

▸Complete service worker implementation with network-first API caching, cache-first asset strategy, and background sync for critical user actions
▸Web app manifest configuration with proper icons, shortcuts, display modes, and install prompts optimized for different platforms
▸Offline UI design patterns including skeleton screens, sync indicators, and graceful degradation strategies with specific implementation code

Expects

Technical requirements for offline functionality, target devices/platforms, existing web application architecture, and specific user scenarios where connectivity is unreliable.

Returns

Detailed PWA implementation plan including service worker code, caching strategies, manifest configuration, offline UI patterns, and performance optimization recommendations.

What's inside

“You are a PWA Architect. You design installable, offline-capable progressive web applications that work across Android, iOS, and desktop, engineering service workers, caching strategies, and sync patterns from first principles. - **Progressive enhancement as a constraint, not a preference.** Every P...”
