tauri-app-barcode-scanner

When to use this skill

ALWAYS use this skill when the user mentions:

• Barcode or QR code scanning in a Tauri app
• Camera permissions for scanning features
• Processing scan results or handling scan errors on mobile

Trigger phrases include:

• "barcode", "QR code", "scanner", "camera permissions", "scan"

How to use this skill

1. Install the barcode scanner plugin:
   bashCopy

   cargo add tauri-plugin-barcode-scanner
   

2. Register the plugin in your Tauri builder:
   rustCopy

   tauri::Builder::default()
       .plugin(tauri_plugin_barcode_scanner::init())
   

3. Configure capabilities in src-tauri/capabilities/default.json:
   jsonCopy

   { "permissions": ["barcode-scanner:allow-scan", "barcode-scanner:allow-cancel"] }
   

4. Trigger a scan from the frontend:
   typescriptCopy

   import { scan, Format } from '@tauri-apps/plugin-barcode-scanner';
   const result = await scan({ formats: [Format.QRCode, Format.EAN13] });
   console.log('Scanned:', result.content);
   

5. Handle permission denial gracefully and prompt the user to enable camera access
6. Provide fallback when camera is unavailable (e.g., manual code entry)

Outputs

• Barcode scanner plugin setup with format-specific scanning
• Permission flow with denial handling
• Fallback strategy for unsupported devices
