## Core Purpose
- **Primary Function**: Provide a comprehensive set of web components for building status monitoring dashboards
- **Target Audience**: Developers building status pages for services using UptimeLink monitoring
- **Key Features**: Real-time status display, incident management, historical data visualization

## Architecture
- **Package Name**: @uptime.link/statuspage (v1.0.74) 
- **Project Type**: Web Component Catalog (wcc)
- **Module Type**: ESM (ECMAScript Modules)
- **Distribution**: Private npm package on verdaccio.lossless.one registry
- **License**: UNLICENSED (proprietary to Lossless GmbH)

## Technology Stack
- **Framework**: @design.estate/dees-element - A web components framework with:
  - TypeScript decorators for component registration
  - Built-in CSS-in-JS with theme support
  - Shadow DOM encapsulation
  - Property binding system
- **DOM Utilities**: @design.estate/dees-domtools for DOM manipulation
- **Interfaces**: @uptime.link/interfaces for shared data structures
- **Build Tools**:
  - tsbuild: TypeScript compilation with --allowimplicitany flag
  - tsbundle: Creates production bundles for web components
  - tswatch: Development file watching
  - TypeScript target: ES2022 with NodeNext module resolution

## Component Library
The catalog provides 7 main components + 1 internal component:

### Main Components:
1. **upl-statuspage-header**: 
   - Page header with customizable title
   - Action buttons for "Report Incident" and "Subscribe to Updates"
   - Emits custom events: 'reportNewIncident' and 'statusSubscribe'

2. **upl-statuspage-statusbar**:
   - Main status indicator showing overall system health
   - Visual status representation (likely green/yellow/red indicators)

3. **upl-statuspage-assetsselector**:
   - Component for selecting/filtering which assets to view
   - Useful for multi-service status pages

4. **upl-statuspage-statusdetails**:
   - Detailed status information display
   - Shows granular status data for selected services

5. **upl-statuspage-statusmonth**:
   - Monthly calendar view of status history
   - Visual representation of uptime/downtime over time

6. **upl-statuspage-incidents**:
   - Incident management display
   - Properties: currentIncidences and pastIncidences (arrays of IIncident)
   - Supports whitelabel mode
   - Shows active and historical incidents

7. **upl-statuspage-footer**:
   - Page footer with legal information link
   - Customizable legal URL

### Internal Components:
- **uplinternal-miniheading**: Internal component for consistent heading styling

## Data Flow & Integration
- Components receive data through properties (using @property decorator)
- Incident data follows the IIncident interface from @uptime.link/interfaces
- Components are designed to work standalone or together
- Event-driven communication between components

## Styling & Theming
- CSS-in-JS approach using cssManager
- Built-in light/dark theme support via bdTheme() helper
- Font: Inter (loaded via assetbroker)
- Responsive design with max-width constraints (900px)
- Background colors: Light (#eeeeeb) / Dark (#222222)
- Text colors: Light (#333333) / Dark (#ffffff)

## Build Output Structure
- Source: ts_web/ directory
- Compiled output: dist_ts_web/ (ES modules with TypeScript definitions)
- Bundle output: dist_bundle/ (production-ready bundle with source maps)
- Development server: dist_watch/ with index.html for testing

## Usage Pattern
1. Import components from the package
2. Create elements using document.createElement()
3. Set properties programmatically
4. Append to DOM
5. Handle custom events for user interactions

## Recent Updates (from changelog)
- v1.0.74: Improved font loading strategy using single assetbroker link
- v1.0.73: Enhanced documentation and aligned project descriptions
- v1.0.72: Fixed import paths and updated package configurations

## Development Workflow
- `pnpm build`: Compile TypeScript and create production bundle
- `pnpm watch`: Start development server with hot reload
- `pnpm test`: Currently just runs build (no actual tests implemented)
- Demo page available at html/index.html using page1 template

## Key Observations
1. The project follows a consistent pattern for all components
2. Each component is self-contained with its own styling
3. Theme support is built-in for all components
4. The project is part of a larger UptimeLink ecosystem
5. Components are designed for composition into complete status pages
6. No test files are currently implemented despite test infrastructure being set up

## Production Readiness Analysis (v1.0.74)

### Current State
The components are essentially **UI shells** - they have styling and structure but lack actual functionality. They display static/hardcoded content with no real data integration.

### Major Missing Functionality

#### 1. Data Integration
- **No API client or data fetching logic** - components can't retrieve real status data
- **No authentication/authorization** - no secure API communication
- **No real-time updates** - no WebSocket/SSE implementation
- **Static content only** - statusbar always shows "Everything is working normally!"
- **Empty data properties** - currentIncidences/pastIncidences arrays are never populated

#### 2. Component Implementation Gaps
- **upl-statuspage-assetsselector**: Only shows "Hello!" - missing entire asset selection UI
- **upl-statuspage-statusbar**: Hardcoded green status - no dynamic status calculation
- **upl-statuspage-statusdetails**: Shows 48 static green bars - no actual hourly data
- **upl-statuspage-statusmonth**: Shows 150 static green days - no real uptime data
- **upl-statuspage-incidents**: Only shows "No incidents" - missing incident card rendering
- **upl-statuspage-footer**: Placeholder "Hi there" - missing actual footer content

#### 3. Error Handling & States
- No loading indicators during data fetch
- No error states for failed requests
- No offline detection or handling
- No retry mechanisms
- No skeleton screens

#### 4. Accessibility Issues
- No ARIA labels on interactive elements
- No keyboard navigation support
- No focus management
- No screen reader announcements
- Missing semantic HTML (divs instead of buttons/nav)
- No skip navigation links

#### 5. Responsive Design Issues
- Fixed 900px max-width with no proper mobile breakpoints
- Grid layouts won't adapt to small screens
- No touch-friendly tap targets
- Font sizes not responsive

#### 6. Internationalization
- All text hardcoded in English
- No i18n framework or translation system
- No locale-aware date/time formatting
- No RTL language support

#### 7. Missing Infrastructure
- No configuration system for API endpoints
- No analytics integration
- No performance monitoring
- No PWA capabilities
- No export functionality
- No proper TypeScript interfaces for data models
- **No tests whatsoever** despite test infrastructure

### Demo Architecture
- All demos have been updated to use dees-demowrapper with runAfterRender callbacks
- Properties are set dynamically on elements within runAfterRender
- Multiple demo sections show different use cases and states
- Event logging demonstrates interactivity
- Demos can be instrumented with multiple wrappers for different scenarios

### Interfaces Implemented
Created comprehensive TypeScript interfaces in ts_web/interfaces/index.ts:
- IServiceStatus - Service monitoring data
- IOverallStatus - Overall system status
- IIncidentUpdate - Incident update entries
- IIncidentDetails - Full incident information
- IMonthlyUptime - Monthly uptime calendar data
- IStatusHistoryPoint - Hourly status data points
- IStatusPageConfig - Configuration options

### Remaining Tasks
- Integration with actual UptimeLink API
- WebSocket/SSE for real-time updates
- Authentication/authorization implementation
- Accessibility improvements (ARIA labels, keyboard navigation)
- More comprehensive responsive design
- Internationalization system
- Unit and integration tests

### Important Fix Applied
The `dees-demowrapper` component was not functioning because it wasn't being imported. Fixed by adding:
```typescript
import '@design.estate/dees-wcctools/demotools';
```
to `html/index.ts`. This registers the `dees-demowrapper` custom element which properly executes the `runAfterRender` callbacks in demos.
