Why Progressive Web Apps?
Progressive Web Apps combine the best of web and mobile apps. They're fast, reliable, and engaging — delivering app-like experiences without requiring users to visit an app store. In 2026, PWAs are no longer experimental; they're the standard.
Core PWA Technologies
Every PWA is built on three foundational technologies:
- Service Workers — Enable offline functionality, background sync, and push notifications
- Web App Manifest — Defines how your app appears when installed on a device
- HTTPS — Required for service workers and ensures secure data transmission
Performance First
PWAs must be fast. Target these benchmarks:
- First Contentful Paint under 1.5 seconds
- Time to Interactive under 3 seconds
- Lighthouse PWA score above 90
Offline-First Architecture
The best PWAs work seamlessly offline. Use cache-first strategies for static assets and network-first strategies for dynamic content. IndexedDB provides robust client-side storage for complex data.
Getting Started
Start with your existing web app. Add a service worker for caching, create a manifest file, and ensure HTTPS. Frameworks like Next.js and Nuxt make this process straightforward with built-in PWA plugins.
