Camera and Image Handling in React Native: A Technical Deep-Dive

Building camera features in React Native requires careful package selection. The ecosystem has evolved significantly, with some libraries deprecated and others offering modern alternatives. Let's compare these five packages across real-world scenarios.

📷 Core Purpose: What Each Package Actually Does

react-native-camera was the original camera library for React Native. It provided direct camera access with custom UI controls. However, it's now deprecated and archived — the repository is read-only and no longer maintained.

// react-native-camera (DEPRECATED - DO NOT USE IN NEW PROJECTS)
import { RNCamera } from 'react-native-camera';

function CameraScreen() {
  return (
    <RNCamera
      style={{ flex: 1 }}
      type={RNCamera.Constants.Type.back}
      onBarCodeRead={(result) => console.log(result.data)}
    >
      <TouchableOpacity onPress={takePicture}>
        <Text>Capture</Text>
      </TouchableOpacity>
    </RNCamera>
  );
}

react-native-vision-camera is the official successor. It's built on CameraX (Android) and AVFoundation (iOS), offering better performance and frame processing capabilities.

// react-native-vision-camera (RECOMMENDED)
import { Camera, useCameraDevice } from 'react-native-vision-camera';

function CameraScreen() {
  const device = useCameraDevice('back');
  
  return (
    <Camera
      style={{ flex: 1 }}
      device={device}
      isActive={true}
      photo={true}
      onFrameProcessor={(frame) => processFrame(frame)}
    />
  );
}

react-native-camera-kit provides camera access with built-in UI components and a simpler API. It handles more of the UI work for you.

// react-native-camera-kit
import { CameraScreen } from 'react-native-camera-kit';

function CameraScreen() {
  return (
    <CameraScreen
      scanBarcode={true}
      onReadCode={(event) => console.log(event.nativeEvent.codeStringValue)}
      showFrame={true}
    />
  );
}

react-native-image-picker doesn't provide a custom camera UI. Instead, it opens native system dialogs for image selection or quick photo capture.

// react-native-image-picker
import { launchCamera, launchImageLibrary } from 'react-native-image-picker';

async function pickImage() {
  // Open camera
  const cameraResult = await launchCamera({ mediaType: 'photo' });
  
  // Or open gallery
  const galleryResult = await launchImageLibrary({ mediaType: 'photo' });
  
  if (cameraResult.assets) {
    console.log(cameraResult.assets[0].uri);
  }
}

react-native-qrcode-scanner focuses specifically on QR code scanning but depends on the deprecated react-native-camera.

// react-native-qrcode-scanner (DEPENDS ON DEPRECATED PACKAGE)
import QRCodeScanner from 'react-native-qrcode-scanner';

function ScannerScreen() {
  return (
    <QRCodeScanner
      onRead={(e) => console.log(e.data)}
      flashMode={QRCodeScanner.Constants.FlashMode.auto}
    />
  );
}

🛠️ Feature Comparison: What Can Each Package Do?

Custom Camera UI

Package	Custom UI Support	Notes
react-native-camera	✅ Yes	Deprecated
react-native-vision-camera	✅ Yes	Full control, modern API
react-native-camera-kit	✅ Yes	Built-in UI components
react-native-image-picker	❌ No	System dialogs only
react-native-qrcode-scanner	⚠️ Limited	Basic scanner UI only

react-native-vision-camera gives you complete control over the camera preview and overlays:

// Full custom UI with vision-camera
function CustomCamera() {
  const camera = useRef(null);
  
  return (
    <View style={{ flex: 1 }}>
      <Camera
        ref={camera}
        device={device}
        isActive={true}
        style={{ flex: 1 }}
      />
      <View style={{ position: 'absolute', bottom: 50 }}>
        <Button title="Capture" onPress={takePhoto} />
        <Button title="Switch Camera" onPress={toggleCamera} />
      </View>
    </View>
  );
}

react-native-image-picker has no custom UI — you get system dialogs:

// No custom UI possible with image-picker
async function capturePhoto() {
  const result = await launchCamera({
    mediaType: 'photo',
    cameraType: 'back',
    saveToPhotos: true
  });
  // That's it — no custom overlays or controls
}

Barcode and QR Code Scanning

Package	Built-in Scanning	Performance	Notes
react-native-camera	✅ Yes	Good	Deprecated
react-native-vision-camera	✅ Yes	Excellent	Via code scanner frame
react-native-camera-kit	✅ Yes	Good	Built-in prop
react-native-image-picker	❌ No	N/A	Not supported
react-native-qrcode-scanner	✅ Yes	Good	QR only, deprecated dependency

react-native-vision-camera uses frame processors for scanning:

// vision-camera with code scanner
import { useCodeScanner } from 'react-native-vision-camera';

function Scanner() {
  const codeScanner = useCodeScanner({
    codeTypes: ['qr', 'ean-13'],
    onCodeScanned: (codes) => {
      console.log(`Scanned ${codes.length} codes!`);
    }
  });
  
  return (
    <Camera
      device={device}
      isActive={true}
      codeScanner={codeScanner}
      style={{ flex: 1 }}
    />
  );
}

react-native-qrcode-scanner is QR-specific:

// qrcode-scanner (QR only)
function QRScanner() {
  return (
    <QRCodeScanner
      onRead={(e) => Linking.openURL(e.data)}
      topContent={<Text>Scan QR Code</Text>}
      bottomContent={<Text>Point at QR code</Text>}
    />
  );
}

Video Recording

Package	Video Support	Quality Control	Notes
react-native-camera	✅ Yes	Basic	Deprecated
react-native-vision-camera	✅ Yes	Advanced	4K, FPS control
react-native-camera-kit	✅ Yes	Basic	Simple API
react-native-image-picker	✅ Yes	Limited	Via system dialog
react-native-qrcode-scanner	❌ No	N/A	Not supported

react-native-vision-camera offers advanced video controls:

// Advanced video recording with vision-camera
async function recordVideo() {
  if (camera.current) {
    const video = await camera.current.startRecording({
      onRecordingFinished: (video) => console.log(video.path),
      onRecordingError: (error) => console.error(error),
      videoCodec: 'h264',
      videoBitrate: 10000000
    });
  }
}

react-native-image-picker video is limited to system capabilities:

// Basic video via system dialog
async function recordVideo() {
  const result = await launchCamera({
    mediaType: 'video',
    videoQuality: 'high',
    durationLimit: 30
  });
  // Limited to what the system dialog offers
}

Frame Processing and Real-Time Analysis

Package	Frame Access	Performance	Use Cases
react-native-camera	⚠️ Limited	Poor	Legacy only
react-native-vision-camera	✅ Yes	Excellent	ML, filters, analysis
react-native-camera-kit	❌ No	N/A	Not supported
react-native-image-picker	❌ No	N/A	Not supported
react-native-qrcode-scanner	❌ No	N/A	Not supported

react-native-vision-camera is the only modern option for frame processing:

// Real-time frame processing
function FrameProcessorCamera() {
  const frameProcessor = useFrameProcessor((frame) => {
    'worklet';
    // Access frame data for ML or filters
    const imageData = frame.toRGBArray();
    // Process with vision-js or custom logic
  }, []);
  
  return (
    <Camera
      device={device}
      isActive={true}
      frameProcessor={frameProcessor}
      pixelFormat="rgb"
      style={{ flex: 1 }}
    />
  );
}

⚠️ Maintenance and Future-Proofing

This is critical for architectural decisions:

Package	Status	Recommendation
react-native-camera	❌ Deprecated/Archived	DO NOT USE
react-native-vision-camera	✅ Active	RECOMMENDED
react-native-camera-kit	✅ Active	Consider for simple needs
react-native-image-picker	✅ Active	RECOMMENDED for image picking
react-native-qrcode-scanner	⚠️ Deprecated Dependency	AVOID (use vision-camera instead)

react-native-camera repository message:

"This repository has been archived. Please migrate to react-native-vision-camera."

react-native-qrcode-scanner inherits this problem since it depends on react-native-camera internally. For QR scanning in new projects, use vision-camera's useCodeScanner hook instead.

🎯 Real-World Decision Scenarios

Scenario 1: Profile Picture Upload

You need users to upload a profile photo — either from gallery or quick camera capture.

✅ Best choice: react-native-image-picker

// Simple and effective for this use case
import { launchImageLibrary } from 'react-native-image-picker';

async function uploadProfilePicture() {
  const result = await launchImageLibrary({
    mediaType: 'photo',
    selectionLimit: 1,
    maxWidth: 512,
    maxHeight: 512
  });
  
  if (result.assets) {
    await uploadToServer(result.assets[0].uri);
  }
}

Why? No need for custom camera UI. System dialogs are familiar to users and require minimal code.

Scenario 2: Document Scanning App

You're building an app that scans documents with edge detection and perspective correction.

✅ Best choice: react-native-vision-camera

// Full control for document scanning
function DocumentScanner() {
  const frameProcessor = useFrameProcessor((frame) => {
    'worklet';
    // Run edge detection algorithm
    const edges = detectDocumentEdges(frame);
    // Apply perspective correction
  }, []);
  
  return (
    <Camera
      device={device}
      isActive={true}
      frameProcessor={frameProcessor}
      photo={true}
    />
  );
}

Why? You need frame access for image processing. Only vision-camera provides this with good performance.

Scenario 3: QR Code Payment Scanner

Your app needs to scan QR codes for payments with high reliability.

✅ Best choice: react-native-vision-camera (NOT qrcode-scanner)

// Modern QR scanning
function PaymentScanner() {
  const codeScanner = useCodeScanner({
    codeTypes: ['qr'],
    onCodeScanned: async (codes) => {
      const paymentData = parsePaymentQR(codes[0].value);
      await processPayment(paymentData);
    }
  });
  
  return (
    <Camera
      device={device}
      isActive={true}
      codeScanner={codeScanner}
      style={{ flex: 1 }}
    />
  );
}

Why? react-native-qrcode-scanner depends on deprecated code. Vision-camera offers better performance and active maintenance.

Scenario 4: Social Media Camera with Filters

You're building a camera with real-time filters, stickers, and effects.

✅ Best choice: react-native-vision-camera

// Real-time filters with frame processing
function FilterCamera() {
  const frameProcessor = useFrameProcessor((frame) => {
    'worklet';
    // Apply filter using vision-js
    applySepiaFilter(frame);
    // Add overlay stickers
    renderStickers(frame);
  }, []);
  
  return (
    <Camera
      device={device}
      isActive={true}
      frameProcessor={frameProcessor}
      pixelFormat="rgb"
    />
  );
}

Why? Frame processing is essential. Vision-camera is the only actively maintained option with this capability.

Scenario 5: Simple Camera with Built-in UI

You need a camera screen quickly with minimal customization.

✅ Best choice: react-native-camera-kit

// Quick setup with built-in UI
function QuickCamera() {
  return (
    <CameraScreen
      scanBarcode={true}
      onReadCode={(event) => handleScan(event)}
      flashMode="auto"
      cameraType="back"
    />
  );
}

Why? Less code, built-in UI components work out of the box. Good for MVPs or simple use cases.

Migration path:

If you're using react-native-camera or react-native-qrcode-scanner, plan to migrate to react-native-vision-camera. The API is different but offers better performance and long-term support.

// Migration example: react-native-camera → vision-camera
// OLD (react-native-camera)
<RNCamera onBarCodeRead={handleScan} />

// NEW (react-native-vision-camera)
const codeScanner = useCodeScanner({ onCodeScanned: handleScan });
<Camera codeScanner={codeScanner} />

🔑 Key Takeaways

• react-native-vision-camera is the modern standard for custom camera implementations
• react-native-image-picker remains the best choice for simple image selection
• Deprecated packages should not be used in new projects — plan migrations for existing ones
• Frame processing is only viable with vision-camera in the modern ecosystem
• QR scanning should use vision-camera's useCodeScanner, not qrcode-scanner

Choose based on your specific needs, but always prioritize actively maintained packages for production applications.
