-# Microservice Status Dashboard
-
-A complete Flutter Web and Dart HTTP application for monitoring microservice health status in real-time.
-
-## What This Template Does
-
-This is a **production-ready foundation** for building service monitoring dashboards. It demonstrates:
-
-- **Real-time health monitoring** of multiple services/APIs
-- **Visual status indicators** (green=online, red=offline, grey=checking)
-- **Full-stack architecture** with Dart backend and Flutter frontend
-- **Self-monitoring** - the backend monitors its own health
-- **Extensible design** for adding custom services and alerting
-
-## Real-World Use Cases
-
-**DevOps & SRE Teams:**
-- Monitor critical APIs, databases, and external dependencies
-- Create status pages for incident response
-- Verify service health after deployments
-- Track uptime of microservices in distributed systems
-
-**Development Teams:**
-- Monitor development/staging environments
-- Check service dependencies before releases
-- Create internal dashboards for service visibility
-
-**Business Operations:**
-- Public status pages for customers
-- Monitor third-party service dependencies
-- Track critical business service availability

-## Features
-
-### Backend (Dart HTTP Server)
-- Lightweight HTTP server running on port 3000
-- **GET `/api/services`** - Returns list of services to monitor
-- **GET `/api/health`** - Health check endpoint for the backend itself
-- CORS headers configured for cross-origin requests
-- No external dependencies (uses built-in `dart:io`)
-- Monitored services include:
-  - **Dashboard Backend** (self-monitoring via `/api/health`)
-  - **Google DNS** (8.8.8.8)
-  - **Public APIs** (api.publicapis.org)
-  - **GitHub API** (api.github.com)
-  - **JSONPlaceholder** (jsonplaceholder.typicode.com)
-  - **HttpBin** (httpbin.org)
-
-### Frontend (Flutter Web)
-- Material Design 3 dashboard interface
-- **Real-time health monitoring** with automatic status updates
-- **Visual status indicators:** Loading (grey spinner), Online (green), Offline (red)
-- **Summary statistics** showing total/online/offline/checking counts
-- **Manual refresh** functionality and per-service re-check
-- **Responsive design** with cards and interactive list tiles
-- **Progressive Web App** (PWA) capabilities

-   cd backend
-   dart run bin/server_simple.dart
-   ```
-   Server will start on `http://localhost:3000`

 ## API Endpoints
 
-### GET /api/services
-Returns a JSON array of service objects to monitor:
-
-```json
-[
-  {
-    "name": "Dashboard Backend",
-    "url": "/api/health"
-  },
-  {
-    "name": "Google DNS",
-    "url": "https://8.8.8.8"
-  },
-  {
-    "name": "Public API", 
-    "url": "https://api.publicapis.org/entries"
-  }
-]
-```
-
-### GET /api/health
-Backend self-monitoring endpoint:
-
-```json
-{
-  "status": "healthy",
-  "timestamp": "2025-08-20T10:30:00.000Z",
-  "service": "microservice-dashboard-backend"
-}
-```
-
-## Health Check Logic
-
-The frontend performs the following health monitoring:
-1. Fetches service list from backend `/api/services` endpoint
-2. For each service, makes a HEAD request to the service URL
-3. **Status 200-299:** Service is marked as "Online" (green)
-4. **Any error or non-2xx status:** Service is marked as "Offline" (red)
-5. **During check:** Service shows "Checking..." (grey with spinner)
-6. **Self-monitoring:** Backend monitors its own health via `/api/health`
-
-## Extending the Dashboard
-
-### Adding Your Own Services
-
-Replace the demo services in `backend/bin/server_simple.dart`:
-
-```dart
-final services = [
-  {
-    'name': 'Dashboard Backend',
-    'url': '/api/health',  // Self-monitoring
-  },
-  {
-    'name': 'User API',
-    'url': 'https://api.yourapp.com/users/health',
-  },
-  {
-    'name': 'Payment Service',
-    'url': 'https://payments.yourapp.com/health',
-  },
-  {
-    'name': 'Database',
-    'url': 'https://db.yourapp.com/ping',
-  },
-  // Add your services here
-];
-```
-
-### Potential Extensions
-
-- **Alerting:** Send notifications when services go down (Slack, email, webhooks)
-- **Historical data:** Store uptime/downtime history in a database
-- **Response time tracking:** Measure and display service response times
-- **Custom health checks:** Support different HTTP methods, authentication, custom headers
-- **Dashboard themes:** Dark mode, custom branding, multiple dashboard views
-- **User management:** Authentication, role-based access, team dashboards
