• Visual status indicator with appropriate colors and icons
• Tooltips explaining each status
• Configurable size (small/default)
• Status-specific styling:
  • Building: Processing color with spinning loading icon
  • Deploying: Processing color with rocket icon
  • Running: Success color with check circle icon
  • Failed: Error color with exclamation icon
  • Stopped: Default color with stop icon

3. PreviewControl (/src/components/PreviewControl.tsx)

UI Integration

App Show Page

• Two-column layout with app details on left, preview control on right
• Seamlessly integrated into existing app detail view
• Preview control only shows when app data is available

App List Page

• Added "Preview Status" column showing current status for each app
• Uses PreviewStatusBadge for consistent visual representation
• Helps users quickly identify which apps have active previews

API Integration

Endpoints Used

• GET ${API_URL}/apps/{id}/preview - Get preview status
• POST ${API_URL}/apps/{id}/preview - Start preview
• POST ${API_URL}/apps/{id}/preview/stop - Stop preview
  
• GET ${API_URL}/apps/{id}/preview/logs - Get preview logs

Configuration

• Uses centralized API_URL from /src/config.ts
• Properly handles environment variables via VITE_API_URL
• Consistent with other API calls in the application

Features

• Automatic status polling during build/deploy phases (every 3 seconds)
• Error handling with user-friendly messages

• Success/error notifications
• Proper authentication and headers handling

User Experience

Visual Feedback

Functionality

• One-click preview start/stop
• Direct access to running previews

URL Generation

• Primary: Uses API-provided URL when available
• Fallback: Generates URL using pattern http://{app-name}-preview-{app-id}.byop.local
• Automatic sanitization of app names for URL compatibility

Error Handling

• Graceful 404 handling for apps without previews
• User-friendly error messages
• Retry capabilities
• Non-blocking error states

Next Steps

• Backend API testing and integration
• Real-time WebSocket integration for log streaming
• Preview expiration warnings
