Desktop application framework

Building cross-platform desktop apps
- 🌐 Web technologies for UI (HTML, CSS, JavaScript, React, Vue, ...)
- 🦀 Rust for backend & system access
Faster than Electron & Lower RAM usage
- No bundled Chromium
- No Node runtime
- Rust compiled to native binary
- Uses system WebView
- Zero HTTP overhead

Core Architecture

Frontend wraps web UI in a desktop window
- Uses the OS’s native webview
Frontend cannot directly access OS
- Frontend calls Rust commands
Rust:
- Read/write files
- Call OS APIs
- Handle security-sensitive logic

**// App Startup:**
OS launches binary
   ↓
Rust main()
   ↓
Tauri runtime initializes
   ↓
Window created
   ↓
WebView created
   ↓
Frontend loaded
   ↓
IPC bridge ready

**// Running:**
Frontend (WebView)
   ↓ invoke()
IPC Message (JSON)
   ↓
Rust Command Handler
   ↓
Rust Logic (FS / DB / OS) -> OS APIs (File, DB, Window, System)
   ↓
Serialized Response
   ↓
JS Promise resolved

Storage

Option	Use Case
Files (JSON / MD)	Notes, config
SQLite (`rusqlite`)	Structured data
Key-Value Store	Settings
OS secure storage	Tokens, secrets
