## 🔌 **API Endpoints**
### **Search API**: `GET /api/search`
```
query: string - Search query
limit: int - Maximum results (default: 20)
file_type: string - Filter by extension (.entity, .plsql, etc.)
module: string - Filter by IFS module
min_complexity: float - Minimum complexity score
max_complexity: float - Maximum complexity score
```
### **Suggestions API**: `GET /api/suggestions`
```
query: string - Partial query for suggestions
limit: int - Maximum suggestions (default: 8)
```
### **File Content API**: `GET /api/file-content`
```
path: string - Full file path to retrieve content
```
## 🚀 **Performance Optimizations**
1. **Debounced Searches**: Prevents excessive API calls while typing
2. **Suggestion Caching**: Server-side caching of frequent suggestions
3. **Lazy Loading**: File content loaded only when viewing files
4. **Optimized Rendering**: Proper React patterns to minimize re-renders
5. **Efficient Filtering**: Client-side filter state management with persistence
## 🎯 **User Experience Improvements**
1. **Instant Feedback**: Real-time search with visual loading states
2. **Context-Aware Suggestions**: Type-specific suggestions with icons and context
3. **Rich Results**: Comprehensive result cards with metadata and previews
4. **Keyboard Navigation**: Full keyboard support for power users
5. **Accessibility**: Focus states, ARIA labels, and keyboard navigation
6. **Progressive Enhancement**: Graceful degradation if JavaScript fails
## 📱 **Mobile Responsiveness**
- Responsive search input that scales to screen size
- Touch-optimized buttons and interactive elements
- Adaptive layout for smaller screens
- Mobile-friendly modal overlays
- Optimized typography for mobile reading
## 🎨 **Visual Design System**
### **Color Palette**
- Primary: Blue (#3b82f6) for interactive elements
- Dark scale: Custom dark-50 to dark-950 for backgrounds
- Semantic colors: Red for errors, Green for success, etc.
- File type colors: Blue (entity), Green (plsql), Purple (client), etc.
### **Typography**
- Clean, modern font stack
- Proper hierarchy with font weights and sizes
- Code fonts for technical content
- Optimized line heights and spacing
### **Component Design**
- Consistent spacing using Tailwind's spacing scale
