Technical Highlights
Auto-Expiring Cloud Uploads
// Files automatically deleted after chosen time
const expirationTimestamp = Math.floor(Date.now() / 1000) + (24 * 60 * 60);
formData.append('expiration', expirationTimestamp.toString());
// Cloudinary handles deletion automatically - no cleanup needed!
Dual Sharing Methods
// Quick Share - Instant, no upload
const qrData = generateQRData(studySet);
// Full Share - Includes media files
const cloudUrl = await uploadToCloudinary(studySet, onProgress, '24h');
const qrData = generateCloudinaryQRData(cloudUrl);
Smart File Handling
// Absolute paths for proper file storage
const filePath = `${FileSystem.documentDirectory}${studySet.id}.pdf`;
const file = new File(filePath);
await file.create();
await file.write(base64Data);
