How to Export TapUI Designs to React Native: Developer Guide

Before exporting, ensure your TapUI design is complete and ready for development.

Prerequisites:

• React Native CLI or Expo project initialized
• Node.js 16+ installed
• Basic understanding of JSX and React Native components
• TapUI account with export credits

Finalize the Visual Design

TapUI's editor lets you refine AI-generated designs. Adjust these elements before export:

• Colors: Set your brand palette. TapUI support hex codes and named colors.
• Typography: Choose font families and sizes. TapUI uses system fonts by default.
• Spacing: Verify padding, margins, and layout grids.
• Components: Ensure buttons, inputs, and cards match your design system.
• Images: Add actual image assets or placeholders with correct dimensions. The more complete your TapUI design, the less manual cleanup you will need after export.

Organize Screen Structure

TapUI exports one screen per file by default. Group related screens together. Name them clearly:

• HomeScreen
• ProfileScreen
• SettingsScreen
• LoginScreen Clear naming makes integration easier. You will import these components by name in your React Native project.

Preview on Device Sizes

TapUI shows designs at different screen sizes. Check your layouts on iPhone and Android dimensions. Ensure responsive behavior looks correct. Fix any layout issues before exporting broken code.

Once your design is ready, export to React Native format.

Quick Export Command

# Using TapUI CLI (optional)
tapui export --project-id=xyz --format=react-native --typescript

Select Export Format

In TapUI, click the Export button. Choose React Native from the format options. TapUI support three export modes:

• Standard React Native: Plain React Native components with StyleSheet
• Expo Compatible: Includes Expo-specific imports and patterns
• TypeScript: Adds TypeScript types and interfaces Choose based on your project setup. Most modern projects use TypeScript. Expo users should select Expo Compatible mode.

Configure Export Options

TapUI offers configuration options:

• Include Assets: Export images as base64 or reference paths
• Component Naming: Choose PascalCase or camelCase
• Style Format: StyleSheet objects or inline styles
• Navigation Setup: Include React Navigation boilerplate We recommend:
• PascalCase component names
• StyleSheet for performance
• Asset references (not base64) for smaller bundle size
• Navigation boilerplate if using React Navigation

Download the Export

TapUI generates a ZIP file containing:

tapui-export/
├── components/
│   ├── HomeScreen.js
│   ├── ProfileScreen.js
│   └── shared/
│       ├── Button.js
│       ├── Card.js

└── README.md

The README explains the file structure and integration steps specific to your export.

Before integrating, review the generated code. TapUI produces clean output, but you should understand what you are importing.

Code Quality Standards

TapUI-generated React Native code follows industry best practices:

• ✅ Functional components with hooks (no class components)
• ✅ StyleSheet.create() for optimal performance
• ✅ Platform.select() for cross-platform consistency
• ✅ PropTypes or TypeScript interfaces for type safety
• ✅ JSDoc comments for complex components

Component Structure

Each screen exports as a React component:

// HomeScreen.tsx - TypeScript Example
import React from 'react';
import { View, Text, StyleSheet, TouchableOpacity } from 'react-native';

interface HomeScreenProps {
  onGetStarted: () => void;
}

const HomeScreen: React.FC<HomeScreenProps> = ({ onGetStarted }) => {
  return (
    <View style={styles.container}>
      <Text style={styles.title}>Welcome</Text>
      <TouchableOpacity 
        style={styles.button}
        onPress={onGetStarted}
        activeOpacity={0.8}
      >
        <Text style={styles.buttonText}>Get Started</Text>
      </TouchableOpacity>
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    padding: 20,
    backgroundColor: '#ffffff',
  },
  title: {
    fontSize: 24,
    fontWeight: 'bold',
    marginBottom: 16,
    color: '#1a1a1a',
  },
  button: {
    backgroundColor: '#007AFF',
    paddingVertical: 16,
    paddingHorizontal: 32,
    borderRadius: 12,
    minHeight: 56, // Accessibility: 44px minimum touch target
    justifyContent: 'center',
    alignItems: 'center',
  },
  buttonText: {
    color: '#ffffff',
    fontSize: 16,
    fontWeight: '600',
    textAlign: 'center',
  },
});

export default HomeScreen;

This follows standard React Native patterns. Functional components with TypeScript. StyleSheet for optimal performance. Platform-agnostic components from react-native.

Check for Platform-Specific Code

TapUI handles iOS and Android differences automatically. Look for Platform.select() usage:

const styles = StyleSheet.create({
  shadow: {
    ...Platform.select({
      ios: {
        shadowColor: '#000',
        shadowOffset: { width: 0, height: 2 },
        shadowOpacity: 0.25,
        shadowRadius: 3.84,
      },
      android: {
        elevation: 5,
      },
    }),
  },
});

This ensures consistent appearance across platforms. TapUI generates these automatically for shadows, fonts, and other platform-varying properties.

Verify Component Extraction

TapUI extracts reusable components into separate files. Check the shared/ folder for:

• Button.js - Consistent button component
• Card.js - Card container with styling
• Header.js - Navigation header
• Input.js - Text input with consistent styling Using these shared components ensures consistency. Modify them in one place to update all screens.

Review Asset References

Images export to the assets/images/ folder. The code references them:

import Logo from '../assets/images/logo.png';
<Image source={Logo} style={styles.logo} />

Ensure these paths will resolve correctly in your project structure. You may need to adjust relative paths based on where you place the components.

Now add the exported code to your existing project or new project.

Integration Checklist

• Copy components to src/components/tapui/
• Copy assets to src/assets/images/
• Update import paths for your project structure
• Install required dependencies
• Configure navigation routes
• Add business logic and state management

Option A: New React Native Project

If starting fresh, create a project first:

# With React Native CLI
npx react-native init MyApp
# Or with Expo
npx create-expo-app MyApp

Then copy the exported files into your project.

Option B: Existing Project

For existing projects, you will merge the TapUI code into your codebase.

Copy Component Files

Copy the exported components/ folder into your project. Place it at src/components/tapui/ or similar:

mkdir -p src/components/tapui
cp -r tapui-export/components/* src/components/tapui/

Copy Assets

Copy images to your assets folder:

cp -r tapui-export/assets/images/* src/assets/images/

Copy Shared Styles

If TapUI exported a theme file, copy it:

cp tapui-export/styles/theme.js src/styles/tapui-theme.js

Update Import Paths

The exported code uses relative paths like ../assets/. You may need to update these based on your project structure. For example, if your project uses absolute imports:

// Before (exported code)
import Logo from '../assets/images/logo.png';
// After (your project)
import Logo from '@/assets/images/logo.png';

Use find-and-replace or your IDE's refactor tools to update all imports consistently.

Install Required Dependencies

TapUI uses standard React Native components. No special dependencies required. However, if your design uses icons, you may need vector icon libraries:

# For React Native CLI
npm install react-native-vector-icons
# For Expo
npx expo install @expo/vector-icons

Check the exported README for any specific dependency requirements.

Connect to Navigation

Most apps need navigation between screens. TapUI optionally generates React Navigation boilerplate.

With React Navigation

If you use React Navigation, wire up the screens:

// App.js
import { NavigationContainer } from '@react-navigation/native';
import { createNativeStackNavigator } from '@react-navigation/native-stack';
import HomeScreen from './src/components/tapui/HomeScreen';
import ProfileScreen from './src/components/tapui/ProfileScreen';
const Stack = createNativeStackNavigator();
function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen name="Profile" component={ProfileScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}
export default App;

With Expo Router

For Expo projects using file-based routing:

# Copy screens to app directory
cp src/components/tapui/HomeScreen.js app/index.js
cp src/components/tapui/ProfileScreen.js app/profile.js

Expo Router automatically creates routes based on file structure.

The exported code contains UI only. You need to add state, data fetching, and interactions.

Add State Management

Convert static screens to interactive ones:

import React, { useState } from 'react';
const HomeScreen = () => {
  const [count, setCount] = useState(0);
  return (
    <View style={styles.container}>
      <Text style={styles.title}>Count: {count}</Text>
      <TouchableOpacity 
        style={styles.button}
        onPress={() => setCount(count + 1)}
      >
        <Text style={styles.buttonText}>Increment</Text>
      </TouchableOpacity>
    </View>
  );
};

Connect to APIs

Add data fetching with React hooks and error handling:

import React, { useEffect, useState, useCallback } from 'react';
import { View, Text, ActivityIndicator, RefreshControl } from 'react-native';

const ProfileScreen = () => {
  const [user, setUser] = useState(null);
  const [loading, setLoading] = useState(true);
  const [error, setError] = useState(null);
  const [refreshing, setRefreshing] = useState(false);

  const fetchUserData = useCallback(async () => {
    try {
      const response = await fetch('/api/user/profile');
      if (!response.ok) throw new Error('Failed to fetch');
      const data = await response.json();
      setUser(data);
      setError(null);
    } catch (err) {
      setError(err.message);
    } finally {
      setLoading(false);
      setRefreshing(false);
    }
  }, []);

  useEffect(() => {
    fetchUserData();
  }, [fetchUserData]);

  const onRefresh = useCallback(() => {
    setRefreshing(true);
    fetchUserData();
  }, [fetchUserData]);

  if (loading) {
    return (
      <View style={styles.centered}>
        <ActivityIndicator size="large" color="#007AFF" />
      </View>
    );
  }

  if (error) {
    return (
      <View style={styles.centered}>
        <Text style={styles.errorText}>{error}</Text>
        <Button title="Retry" onPress={fetchUserData} />
      </View>
    );
  }

  return (
    <ScrollView
      refreshControl={
        <RefreshControl refreshing={refreshing} onRefresh={onRefresh} />
      }
    >
      <View style={styles.container}>
        <Text style={styles.name}>{user?.name}</Text>
        <Text style={styles.email}>{user?.email}</Text>
      </View>
    </ScrollView>
  );
};

Handle User Input

Add form handling to input components:

const [email, setEmail] = useState('');
<TextInput
  style={styles.input}
  value={email}
  onChangeText={setEmail}
  placeholder="Enter email"
  keyboardType="email-address"
/>

Always test exported code on physical devices, not just simulators.

iOS Testing

# Run on iOS simulator
npx react-native run-ios
# Or open in Xcode for device testing
open ios/MyApp.xcworkspace

Check for:

• Safe area handling (notch, dynamic island)
• Touch target sizes (44px minimum)
• Font rendering
• Shadow performance

Android Testing

# Run on Android emulator
npx react-native run-android
# Or build APK for device testing
cd android && ./gradlew assembleRelease

Check for:

• Elevation shadows
• Back button handling
• Keyboard behavior
• Status bar styling

Cross-Platform Consistency

Compare iOS and Android side-by-side. TapUI generates platform-appropriate code, but verify:

• Colors match your brand exactly
• Spacing feels consistent
• Fonts render clearly on both platforms
• Animations perform smoothly

Here are problems you might encounter and their solutions:

Issue: Images Not Loading

Cause: Path resolution or missing assets Solution: Verify image paths. Ensure assets are included in the bundle:

# For React Native CLI
npx react-native-asset
# For Expo, images auto-bundle if in assets folder

Issue: Styles Look Different

Cause: Global styles conflicting with TapUI styles Solution: Check for global CSS or theme providers overriding TapUI styles. Use StyleSheet specificity or !important sparingly.

Issue: Touch Targets Too Small

Cause: Custom styling reduced button sizes Solution: Ensure buttons meet 44px minimum touch target. Update styles:

button: {
  minHeight: 44,
  minWidth: 44,
  // ... other styles
}

Issue: Navigation Not Working

Cause: Missing navigation props or incorrect setup Solution: Pass navigation props to screens:

<Stack.Screen name="Home">
  {props => <HomeScreen {...props} />}
</Stack.Screen>

Issue: Fonts Not Applied

Cause: Custom fonts not linked Solution: Link custom fonts in React Native:

npx react-native link

Or for Expo, load fonts in app entry:

import { useFonts } from 'expo-font';
const [fontsLoaded] = useFonts({
  'CustomFont': require('./assets/fonts/CustomFont.ttf'),
});

Follow these guidelines for smooth integration:

Keep TapUI Code Separate

Maintain TapUI exports in a dedicated folder (src/components/tapui/). This isolates generated code from hand-written code. You can regenerate without affecting custom logic.

Version Control Exports

Commit exported code to git. Tag exports with the TapUI design version:

git add src/components/tapui/
git commit -m "Add TapUI exports v1.2 - login flow redesign"

This lets you roll back if a new export breaks something.

Document Customizations

When you modify exported code, add comments:

// MODIFIED: Added onPress handler for navigation
// Original TapUI exports did not include navigation
<TouchableOpacity onPress={() => navigation.navigate('Profile')}>

This helps when regenerating from TapUI. You will know what customizations to reapply.

Use TypeScript

If your project uses TypeScript, export TypeScript from TapUI. You get type safety and better IDE support:

interface HomeScreenProps {
  navigation: NativeStackNavigationProp<RootStackParamList>;
}
const HomeScreen: React.FC<HomeScreenProps> = ({ navigation }) => {
  // Component implementation
};

Optimize Performance

TapUI generates clean code, but optimize for production:

• Use React.memo() for pure components
• Lazy load screens with React.lazy()
• Optimize images before adding to assets
• Profile with React DevTools

For teams with specific needs, customize the export process:

Custom Component Library

If you have a design system, replace TapUI's shared components with your own:

// Instead of TapUI Button
// import Button from './shared/Button';
// Use your design system
import { Button } from '@yourcompany/design-system';

Theme Integration

Merge TapUI styles with your existing theme:

import { ThemeProvider } from './theme';
import TapUITheme from './tapui-theme';
const mergedTheme = {
  ...TapUITheme,
  colors: {
    ...TapUITheme.colors,
    primary: '#your-brand-color',
  },
};

Automated Export Pipeline

For continuous integration, automate TapUI exports:

# Script to export and integrate
curl -X POST https://api.tapui.dev/export \
  -H "Authorization: Bearer $TAPUI_API_KEY" \
  -d '{"project_id": "proj_123", "format": "react-native"}' \
  -o tapui-export.zip
unzip tapui-export.zip -d src/components/tapui/

Is the exported code production-ready?

Yes, with review. TapUI generates clean, standard React Native code. You should test thoroughly and add business logic. The UI foundation is solid for production use.

Can I edit exported code?

Yes. Exported code is standard React Native. Modify it like any other component. Just track changes so you can reapply them if you regenerate from TapUI.

Does TapUI support Expo?

Yes. Choose Expo Compatible export mode. The code uses Expo SDK patterns and works with Expo Go and custom dev clients.

Can I export to TypeScript?

Yes. Select TypeScript export option. You get .tsx files with proper type definitions.

What React Native version does TapUI target?

TapUI generates code compatible with React Native 0.70+. It uses modern React patterns (hooks, functional components) that work in current versions.

Do I need to install special dependencies?

No. TapUI uses only standard React Native components. If your design uses icons, you may need vector icon libraries. The export README lists any requirements.

Can I use TapUI with existing React Native projects?

Yes. Exported code integrates into existing projects. You may need to adjust import paths and merge with your existing navigation setup.

How do I handle design updates?

Regenerate from TapUI and compare with your modified version. Use git diff to see what changed. Reapply your customizations to the new export.

Does TapUI exports navigation code?

Optionally. You can include React Navigation boilerplate in the export. Or just export screens and wire them into your existing navigation.

Can I customize the export format?

Yes. TapUI offers configuration options for naming conventions, style format, and asset handling. Choose options that match your project standards.

TapUI transforms how teams build React Native apps. Designers create visually. Developers receive clean code. The handoff friction disappears.
