Earlier, we worked with a REST API. Today, we connect our React Native Expo app to a real Supabase PostgreSQL database and implement complete CRUD operations. We’ll also run database migrations and test the app on a physical device.

Welcome to Video #24 of AI Mobile Engineer 2026 by The Techzeen. In this practical lesson, we integrate Supabase PostgreSQL with React Native and Expo Router, then build the app’s data workflow from creating records to updating and deleting them.

What we build in this video

Supabase PostgreSQL Integration

Connect the React Native Expo app to Supabase
Configure the project to work with the PostgreSQL database

Database Migrations

Set up the database schema through migrations
Run the migrations and prepare the database for the app

Complete CRUD Operations

Create: Insert new records
Read: Fetch and display saved records
Update: Edit existing records
Delete: Remove records from the database

Physical Device Testing

Run the app on a real phone
Test the CRUD workflow and verify that data is saved in Supabase PostgreSQL
AI-native development workflow

Think → Prompt → Review → Debug → Test → Ship
