# Connection Components and Diagnostics Updates

## GitHub Connection Component Changes

  - Changed from `<Button>` component to native `<button>` element
  - Added red background (`bg-red-500`) with hover effect (`hover:bg-red-600`)
  - Updated icon from `i-ph:sign-out` to `i-ph:plug`
  - Simplified text to just "Disconnect"
  - Added connection status indicator with check-circle icon and "Connected to GitHub" text

## ConnectionDiagnostics Tab Updates
### Added New Connection Diagnostics
- Implemented diagnostics for Vercel and Supabase connections
- Added new helper function `safeJsonParse` for safer JSON parsing operations

### Diagnostic Checks Added
- **Vercel Diagnostics:**
  - LocalStorage token verification

  - Connection status validation
  - Reset functionality for Vercel connection

- **Supabase Diagnostics:**
  - LocalStorage credentials verification
  - API endpoint connectivity test
  - Connection status validation
  - Reset functionality for Supabase connection

### UI Enhancements

- Enhanced error handling and user feedback

### Function Updates
- Extended `runDiagnostics` function to include Vercel and Supabase checks
- Added new reset helper functions for each connection type
- Improved error handling and status reporting
- Enhanced toast notifications for better user feedback

### Visual Consistency
- Matched styling of new diagnostic cards with existing GitHub and Netlify cards

- Maintained consistent spacing and layout patterns

### Code Structure
- Organized diagnostic checks into clear, separate sections
- Improved error handling and type safety

These changes ensure a consistent user experience across all connection types while providing robust diagnostic capabilities for troubleshooting connection issues.

# DataTab.tsx Changes

## Code Cleanup
- Removed unused variables from useDataOperations hook:
  - Removed `handleExportAPIKeys`
  - Removed `handleUndo`
  - Removed `lastOperation`

This change improves code quality by removing unused variables and resolves ESLint warnings without affecting any functionality.
