What this service covers

A Progressive Web App uses web technologies and can be installed from supported browsers without becoming identical to a native app. I define target browsers, install flow, cacheable screens, network-only actions, update behavior, push requirements, and data-conflict rules first.

The implementation can include the web app manifest, icons, service worker, cache strategies, offline fallback, background synchronization where supported, push notifications, authentication, and API integration. Offline behavior is tested only for the screens and data named in scope.

Browser and operating-system support differs, especially for notifications, background work, storage limits, and installation prompts. Payments, initial login, live data, and server validation usually need a connection. App-store packaging and approval are separate.

What's included

  • Installable manifest for supported browsers
  • Defined service-worker and offline routes
  • Scoped notification infrastructure
  • Browser and device support matrix

Frequently asked questions

How is a PWA different from a native mobile app?

A PWA is distributed through the web and shares a web codebase. Native apps can access more device APIs. PWA capabilities vary by browser and operating system.

Can a PWA be published in an app store?

It can sometimes be packaged for store distribution, but publisher accounts, policy compliance, platform tooling, and review are separate. Approval is controlled by each store.

Will the PWA work without internet?

Only the screens and data explicitly cached for offline use. Live data, payments, initial login, and server validation need connectivity, while sync conflicts require defined rules.
