What a PWA can provide
- Installability from supported browsers.
- Responsive layouts for desktop and mobile.
- Service-worker controlled caching where it improves resilience.
- Offline or degraded-mode behavior for explicitly supported workflows.
- Web Push or other browser capabilities when the product actually needs them.
Offline is a product decision
Caching everything is not a sound offline strategy. Data freshness, permissions, conflict handling and synchronization must be defined per workflow. Some screens should remain online-only when stale data would be misleading.
Consent-first browser state
If a product requires consent before browser storage or client-side personalization, the bootstrap sequence must respect that constraint. Service workers, localStorage, IndexedDB and third-party scripts should not be initialized before the allowed stage.
When PWA is a good fit
PWA is useful when one web codebase should serve desktop and mobile users, especially for dashboards, field workflows, portals and frequently used operational tools.
