## Overview
Refactored the monolithic dashboard page (~1200 lines) into a modular architecture following the project's global layout pattern. The main `Detail/index.js` is now simplified to match other page entry files like `Midjourney/index.js`.
## Changes Made
### 🏗️ Architecture Changes
- **Before**: Single large file `pages/Detail/index.js` containing all dashboard logic
- **After**: Modular structure with dedicated hooks, components, and helpers
### 📁 New Files Created
- `hooks/dashboard/useDashboardData.js` - Core data management and API calls
- `hooks/dashboard/useDashboardStats.js` - Statistics computation and memoization
- `hooks/dashboard/useDashboardCharts.js` - Chart specifications and data processing
- `constants/dashboard.constants.js` - UI config, time options, and chart defaults
- `helpers/dashboard.js` - Utility functions for data processing and UI helpers
- `components/dashboard/index.jsx` - Main dashboard component integrating all modules
- `components/dashboard/modals/SearchModal.jsx` - Search modal component
### 🔧 Updated Files
- `constants/index.js` - Added dashboard constants export
- `helpers/index.js` - Added dashboard helpers export
- `pages/Detail/index.js` - Simplified to minimal wrapper (~20 lines)
### 🐛 Bug Fixes
- Fixed SearchModal DatePicker onChange to properly convert Date objects to timestamp strings
- Added missing localStorage update for `data_export_default_time` persistence
- Corrected data flow between search confirmation and chart updates
- Ensured proper chart data refresh after search parameter changes
### ✨ Key Improvements
- **Separation of Concerns**: Data, stats, and charts logic isolated into dedicated hooks
- **Reusability**: Components and hooks can be easily reused across the application
- **Maintainability**: Smaller, focused files easier to understand and modify
- **Consistency**: Follows established project patterns for global folder organization
- **Performance**: Proper memoization and callback optimization maintained
### 🎯 Functional Verification
- ✅ All dashboard panels (model analysis, resource consumption, performance metrics) update correctly
- ✅ Search functionality works with proper parameter validation
- ✅ Chart data refreshes properly after search/filter operations
- ✅ User interface remains identical to original implementation
- ✅ All existing features preserved without regression
### 🔄 Data Flow
```
User Input → SearchModal → useDashboardData → API Call → useDashboardCharts → UI Update
```
## Breaking Changes
None. All existing functionality preserved.
## Migration Notes
The refactored dashboard maintains 100% API compatibility and identical user experience while providing a cleaner, more maintainable codebase structure.
