Push notifications have to register the device and route to the right deep link. Offline storage has to keep the user productive when the network is gone. Error handling has to surface failures without bouncing the user to a crash screen. None of these are visible in a Hello World scaffold; all of them are required for a real product. The team that ships without them rebuilds the foundation halfway through development, which is the most expensive moment to redo it."

Navigation structure, API client with auth and refresh, push notification registration, offline storage, error boundaries, CI pipeline. The output is calibrated to the team's chosen framework (React Native, Flutter, native iOS, native Android) and integrates with the existing backend. The discipline is to ship the right foundation rather than the smallest one."

It does not handle token refresh, does not register for push, has no offline strategy, no error boundary, and no CI. The team builds these on top of the boilerplate over weeks, often discovering missing layers when a customer reports a specific failure. The boilerplate is the right starting point for a tutorial; it is the wrong starting point for a product."

Push notifications: device registration, deep link routing, background handling. Offline storage: cached queries, optimistic mutations, sync on reconnect. Error handling: error boundaries, crash reporting (Sentry, Crashlytics), graceful degradation. CI: build for both platforms, test runs, beta distribution (TestFlight, Internal Testing). Each layer is small individually and considerable together."

React Native gets React Navigation, TanStack Query with offline persistence, Firebase Cloud Messaging or Expo notifications, Sentry.

The CI pipeline integrates with Fastlane for the release work and the project's existing CI tool for builds."
