On Day 2, we’ll focus on setting up the basic structure for your deepfake face swap app using React Native. This includes creating a home screen, adding navigation, and preparing placeholders for features like image uploads and camera capture.
1. Setting Up the Project Structure
Step 1: Create a New Project
If you haven’t already initialized the project, do so now:
expo init deepfake-face-swap
cd deepfake-face-swap
Choose the blank template when prompted.
Step 2: Install Required Libraries
Install the following dependencies for our app:
- React Navigation: For navigating between screens.
- Expo Image Picker: To upload images from the gallery or capture photos with the camera.
Run these commands:
npm install @react-navigation/native react-native-screens react-native-safe-area-context react-native-gesture-handler react-native-reanimated react-native-stack
expo install expo-image-picker
2. Setting Up Navigation
Step 1: Add a Navigation Container
Create a basic navigation system for switching between screens (e.g., Home, Camera, Face Swap). Update App.js:
import React from 'react';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import HomeScreen from './src/screens/HomeScreen';
import CameraScreen from './src/screens/CameraScreen';
import FaceSwapScreen from './src/screens/FaceSwapScreen';
const Stack = createStackNavigator();
export default function App() {
return (
<NavigationContainer>
<Stack.Navigator initialRouteName="Home">
<Stack.Screen name="Home" component={HomeScreen} />
<Stack.Screen name="Camera" component={CameraScreen} />
<Stack.Screen name="FaceSwap" component={FaceSwapScreen} />
</Stack.Navigator>
</NavigationContainer>
);
}
3. Creating the Home Screen
Step 1: Create HomeScreen.js
Create the HomeScreen.js file in the src/screens/ folder:
import React from 'react';
import { View, Text, Button, StyleSheet } from 'react-native';
export default function HomeScreen({ navigation }) {
return (
<View style={styles.container}>
<Text style={styles.title}>Deepfake Face Swap App</Text>
<Button
title="Capture Image"
onPress={() => navigation.navigate('Camera')}
/>
<Button
title="Upload Image"
onPress={() => navigation.navigate('FaceSwap')}
/>
</View>
);
}
const styles = StyleSheet.create({
container: { flex: 1, justifyContent: 'center', alignItems: 'center' },
title: { fontSize: 24, fontWeight: 'bold', marginBottom: 20 },
});
4. Adding Camera and Face Swap Placeholders
Step 1: Create CameraScreen.js
Add the placeholder for capturing an image:
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
export default function CameraScreen() {
return (
<View style={styles.container}>
<Text style={styles.text}>Camera Screen Placeholder</Text>
</View>
);
}
const styles = StyleSheet.create({
container: { flex: 1, justifyContent: 'center', alignItems: 'center' },
text: { fontSize: 20 },
});
Step 2: Create FaceSwapScreen.js
Add the placeholder for face-swapping functionality:
import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
export default function FaceSwapScreen() {
return (
<View style={styles.container}>
<Text style={styles.text}>Face Swap Screen Placeholder</Text>
</View>
);
}
const styles = StyleSheet.create({
container: { flex: 1, justifyContent: 'center', alignItems: 'center' },
text: { fontSize: 20 },
});
5. Testing the App
Step 1: Start the Development Server
Run the app:
expo start
Step 2: Test Navigation
- Ensure the home screen is displayed by default.
- Test the Capture Image button to navigate to the Camera Screen.
- Test the Upload Image button to navigate to the Face Swap Screen.
6. Next Steps
On Day 3, we’ll:
- Implement functionality for face detection using pre-trained models.
- Integrate an image picker to upload or capture images for face swapping.
