Mobile development

Connecting an Expo app to a web backend

Shared contracts help web and mobile clients agree on data, while platform-specific UI keeps each experience natural.

Start with a clear boundary

Share stable API types and validation without forcing every screen to look identical. Phone and desktop use call for different layouts.

Centralize authentication, request configuration, and error mapping in a small client layer. Keep authorization checks on the server.

Test slow connections, app suspension, and stale data. A good shared architecture reduces duplicate logic while preserving usability.
