## Phase 2: API Layer Development
**Status:** ✅ Completed
### Implementation Details
- Created FastAPI-based REST API for heatmap data
- Implemented three main endpoints:
1. `/api/facilities` - List all facilities with coordinates
2. `/api/facility/{id}/current-detainees` - Detailed facility data
3. `/api/heatmap-data` - Aggregated data with detainee counts
- Added database integration with PostgreSQL
- Implemented proper error handling with HTTP status codes
- Added unit tests and integration tests
### Key Components
- **API Implementation:** `src/ice_locator_mcp/api/heatmap_api.py`
- **Server Script:** `run_heatmap_server.py`

### Features
- CORS support for web/mobile app integration
- Database connection pooling for performance
- Comprehensive error handling and logging
- Type hints for better code maintainability
## Phase 3: Web App Implementation
**Status:** ✅ Completed
### Implementation Details
- Created React + TypeScript web app with Vite build tool
- Implemented interactive heatmap using Leaflet.js and react-leaflet
- Added responsive design with Tailwind CSS
- Created facility list with detainee counts
- Implemented loading states and error handling
### Key Components
- **Main App:** `web-app/src/App.tsx`
- **Heatmap Component:** `web-app/src/components/Heatmap.tsx`
- **Facility List:** `web-app/src/components/FacilityList.tsx`
- **API Client:** `web-app/src/api/heatmapClient.ts`
### Features
- Interactive map with zoom and pan capabilities
- Color-coded markers based on detainee density

- Implemented map visualization using react-native-maps
- Added facility list with detainee counts
### Key Components
- **Heatmap API Client:** `mobile-app/src/heatmap/HeatmapAPI.ts`
- **Heatmap View:** `mobile-app/src/heatmap/HeatmapView.tsx`
- **App Integration:** `mobile-app/App.tsx`
### Features
- Interactive map with facility markers
- Color-coded visualization based on detainee counts
- Facility list with current detainee information
- Tab navigation between search and heatmap views
- Caching for improved performance
- Loading and error states
## Phase 5: Deployment
**Status:** 🚧 In Progress
### Implementation Details
- Created deployment scripts for all components
- Configured production environments

### Data Flow
1. Database stores detainee, facility, and location history data
2. Heatmap API retrieves and aggregates data from database
3. Web and mobile apps fetch data from Heatmap API
4. Users interact with visualizations in web/mobile interfaces
