How to Export TapUI Designs to React Native: Developer Guide

Quick Overview: TapUI to React Native Workflow

| Step | Action | Time Required | |------|--------|---------------| | 1 | Design in TapUI | 5-30 minutes | | 2 | Export to React Native | 1 minute | | 3 | Review exported code | 10-20 minutes | | 4 | Integrate into project | 20-60 minutes | | 5 | Test on devices | 15-30 minutes | | **Total** | | **1-2 hours** | Compare this to manual implementation: days of coding UI from design files. TapUI accelerates the frontend development phase significantly.

Step 1: Design Your Screens in TapUI 🎨

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.

Step 2: Export React Native Code ⚡

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

### Quick Export Command ```bash # 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 │ └── Header.js ├── assets/ │ └── images/ │ ├── logo.png │ └── background.jpg ├── styles/ │ └── theme.js └── README.md ``` The README explains the file structure and integration steps specific to your export.

Step 3: Review the Exported Code 🔍

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: ```jsx // 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: ```jsx 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: ```jsx 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.

Step 4: Integrate into Your React Native Project 🔧

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: ```bash # 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: ```bash mkdir -p src/components/tapui cp -r tapui-export/components/* src/components/tapui/ ``` #### Copy Assets Copy images to your assets folder: ```bash cp -r tapui-export/assets/images/* src/assets/images/ ``` #### Copy Shared Styles If TapUI exported a theme file, copy it: ```bash 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: ```jsx // 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: ```bash # 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: ```jsx // 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: ```bash # 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.

Step 5: Add Business Logic

The exported code contains UI only. You need to add state, data fetching, and interactions. ### Add State Management Convert static screens to interactive ones: ```jsx 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: ```jsx 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: ```jsx const [email, setEmail] = useState(''); <TextInput style={styles.input} value={email} onChangeText={setEmail} placeholder="Enter email" keyboardType="email-address" /> ```

Step 6: Test on Real Devices

Always test exported code on physical devices, not just simulators. ### iOS Testing ```bash # 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 ```bash # 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

Common Integration Issues

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: ```bash # 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: ```jsx button: { minHeight: 44, minWidth: 44, // ... other styles } ``` ### Issue: Navigation Not Working **Cause:** Missing navigation props or incorrect setup **Solution:** Pass navigation props to screens: ```jsx <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: ```bash npx react-native link ``` Or for Expo, load fonts in app entry: ```jsx import { useFonts } from 'expo-font'; const [fontsLoaded] = useFonts({ 'CustomFont': require('./assets/fonts/CustomFont.ttf'), }); ```

Best Practices for TapUI Exports

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: ```bash 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: ```jsx // 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: ```tsx 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

Advanced: Customizing the Export

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: ```jsx // 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: ```jsx 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: ```bash # 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/ ```
