Progressive Web Apps: Building an App-Like Experience Without an App Store

Progressive Web Apps combine web flexibility with selected app-like features. Start with HTTPS, add a Web App Manifest for identity and display settings, and use a Service Worker for caching and request control.

Choose caching strategies carefully: cache-first for static assets and network-first for changing content. Never cache sensitive data. Test installation, bundle size, loading time, offline behavior, and notification consent. A successful PWA is measured by speed, clarity, and resilience on unreliable networks.
