Core idea
PWA support should make the product feel more credible without introducing unsafe offline behavior for authentication, billing, admin, or subscription state.

Mobile app-like UX
Offline-ready fallback
Production-safe boundaries
Why this mattersLink to section
Most SaaS starters stop at responsive layout.
Starter Pro goes further by adding the foundations that make the product feel like a serious application:
- a clean manifest
- professional PWA icons
- maskable icons
- install screenshots
- standalone mode
- splash screen colors
- service worker registration
- offline fallback routing
- mobile-safe viewport behavior
Product perception
Installability and standalone mode are not only technical details. They help the product feel more mature, more complete, and more trustworthy.
PWA architectureLink to section
| File | Responsibility |
|---|---|
app/manifest.ts | PWA manifest, icons, screenshots, install metadata |
app/layout.tsx | metadata, viewport, icons, service worker registration |
app/offline/page.tsx | offline fallback surface |
components/pwa/pwa-register.tsx | client-side service worker registration |
lib/pwa/pwa-config.ts | shared PWA configuration |
public/sw.js | lightweight service worker |
public/pwa/* | icons and screenshots |
Architecture rule
Keep the PWA layer explicit and easy to audit. A starter product should teach the buyer how the system works, not hide it behind unnecessary magic.
System modelLink to section
Manifest layer
The manifest describes how the application appears when installed. It includes app name, display mode, theme colors, icons, screenshots, and app metadata.
Recommended strategyLink to section
Product-quality PWA features
- installable manifest
- standalone display mode
- professional icons
- dashboard screenshots
- offline fallback page
- mobile-safe viewport
Unsafe offline-first shortcuts
- offline billing state
- cached auth truth
- stale admin permissions
- offline destructive actions
- unverified subscription access
Online-first boundariesLink to section
| Area | Recommended approach |
|---|---|
| Authentication | Online-first |
| Billing | Online-first |
| Admin actions | Server-validated |
| Account settings | Server-validated |
| Subscription state | Backend source of truth |
| Offline support | Fallback-only baseline |
Production rule
Redirects, cached UI, and offline pages are UX. Server state remains the source of truth for authentication, billing, permissions, and subscriptions.

Prefer / avoidLink to section
Prefer
- use
app/manifest.tsas the manifest source - keep
public/sw.jslightweight and auditable - use real dashboard screenshots for install surfaces
- keep auth, billing, and admin routes online-first
- treat PWA as progressive enhancement
Avoid
- caching Stripe or billing state as truth
- making authentication work offline
- using oversized screenshots in the manifest
- hiding service worker behavior behind unclear abstractions
- claiming full offline support without synchronization logic
