📱 Read-and-Write-with-SQLite-App

A simple and educational React Native application built with Expo that demonstrates how to read from and write to a local SQLite database on a mobile device. This app is intended for learners and developers who want a practical example of integrating SQLite with React Native using the Expo ecosystem.

✨ Designed for clarity and ease-of-use, this app is perfect for those new to mobile development with Expo and local data storage.

🧭 Introduction

This project was created to help developers understand how to implement local persistent storage using SQLite within an Expo-based React Native app. It provides a minimal yet functional example of creating and managing a user database — ideal for use cases like contact lists, offline storage, and user data management.

✨ Features

📦 Add new user records to a local SQLite database.
📄 Display a real-time list of all users stored in the database.
💾 Uses device-local SQLite storage (offline functionality).
🚀 Built using Expo for fast development and easy deployment.
🎨 Clean UI with user-friendly icons.

⚙️ Installation

Clone the repository:

git clone https://github.com/your-username/Read-and-Write-with-SQLite-App.git
cd Read-and-Write-with-SQLite-App

Install dependencies:
```
npm install
```
Start the Expo development server:
```
npm start
```

▶️ Usage

Open the Expo Go app on your Android/iOS device.
Scan the QR code generated in the terminal or browser.
Use the interface to:
- Add a new user by entering their name.
- View a list of all saved users.

💡 The app runs entirely on the local device — no network required!

📦 Dependencies

React Native (via Expo)
Expo SQLite – for database access
Expo CLI – for development and testing

All dependencies are installed via npm install.

🔧 Configuration

No additional configuration is required. SQLite creates a local .db file on the device, and the database setup is handled automatically when the app starts.

If you wish to modify the schema:

Edit database.js to change the table creation logic.
Reinstall the app to reset the database.

🛠️ Troubleshooting

If the app fails to start, try clearing Expo’s cache:
```
npm start -- --clear
```
Ensure you have the Expo Go app installed on your device.
For Android emulators, ensure they are set up with Google Play services for Expo.
