This article shows how to connect a React Native app to REST APIs using Axios (with optional Fetch), focusing on practical, TypeScript-friendly examples. You’ll learn how to perform GET and POST requests, add robust error handling, write simple tests, and deploy OTA updates with Expo EAS. Examples target React Native 0.75.4 and Expo SDK 51 but are applicable to most modern projects — by the end you’ll have a small posts app that fetches, creates, and handles API-driven data reliably.
