data-fetching

React Query integration with fetch handles API data fetching, caching, and invalidation. You create a reusable network layer using fetch for basic requests, enabling robust error checks and automatic cache management across your app.

API retry strategies with exponential backoff are implemented within your fetch network layer to handle transient failures. This approach systematically delays retried requests, reducing server load and improving data fetching reliability during network instability.

Token management uses expo-secure-store to safely persist authentication tokens. The data fetching layer implements secure storage patterns and refresh flows, automatically attaching tokens to API calls and handling refresh workflows when authentication expires.

Offline support manages API calls when network connectivity is lost, queuing or caching data locally. Online synchronization strategies then resolve pending requests and update the cache automatically once the connection is restored, ensuring data consistency.

Yes, you can use fetch instead of axios for React Query integration. The Skill specifies preferring the native fetch API for network operations, ensuring basic GET and POST requests include robust error handling without adding external HTTP client dependencies.

Environment variables configure different API endpoints and settings for development and production environments. Configuring them ensures your fetch network layer targets the correct backend services, preventing data fetching errors and misdirected authentication flows.
