Last video we learned REST API concepts. Today, we build it for real.

Welcome to Video 19 of AI Mobile Engineer 2026 by The Techzeen.

In this fully practical session, we connect a React Native Expo + Expo Router app with a REST API using Axios and implement complete CRUD operations.

What we implement:
* Set up a REST API using JSON Server
* GET single & all records
* POST new data
* PUT & PATCH updates
* DELETE records
* Axios API integration
* Loading states
* Pagination
* Retry failed requests
* Offline handling
* Modern UI with NativeWind
* Fix the Local IP / Network Error when testing on a physical device
* Complete end-to-end testing on a real phone

We use Gemini for professional prompt engineering and Cursor AI to implement the solution while reviewing, debugging and testing the generated code.
