Architecture

Wallpaper Sync follows a modular architecture:

Components

Electron App

• Handles UI and local storage
• Manages slideshow and wallpaper changes

Next.js API (Vercel)

• Handles uploads
• Generates hash for duplicate detection

Supabase

• Database: stores metadata + hash
• Storage: stores actual images

---

Data Flow

Upload → API → Hash → DB Check → Storage

---

Duplicate Prevention

• SHA256 hash generated for each image
• Stored in database with UNIQUE constraint
• Duplicate uploads are rejected automatically
