Development Workflow

1. Build With Mobile Agent

Describe your app idea and features.

The agent will:

• Create an Expo project
• Build React Native UI components
• Set up the FastAPI backend
• Configure MongoDB
• Implement requested features

2. Test in Preview

During development you can test the app using preview tools.

Best practice:

After implementing a feature, ask the agent:

Test areas include:

• Navigation
• UI behavior
• Data loading
• Error handling
• Forms and validation

3. Download Your Code

When the application is ready:

Download your full project from Rofy.

Your project will include:

• Expo mobile app
• FastAPI backend
• Configuration files
• Assets and resources

Deploying Your Mobile App

Deployment uses Expo Application Services (EAS).

EAS handles:

• Building native app binaries
• Submitting to app stores
• Over-the-air updates

All builds run in the cloud.

You do not need Xcode or Android Studio.

Prerequisites

Before deployment you need:

Expo Account

Create an account at expo.dev

Free tier includes:

• 30 builds per month

Developer Accounts

You only need the stores you plan to publish to.

Setting Up EAS

After downloading your project:

cd your-mobile-app
npm install -g eas-cli
eas login
eas build:configure
