-# Certificate Management in SmartProxy v18+
+# Certificate Management in SmartProxy v19+
 
 ## Overview
 
-SmartProxy v18+ introduces a simplified certificate management system using the new `SmartCertManager` class. This replaces the previous `Port80Handler` and multiple certificate-related modules with a unified, route-based approach.
+SmartProxy v19+ enhances certificate management with support for both global and route-level ACME configuration. This guide covers the updated certificate management system, which now supports flexible configuration hierarchies.
 
 ## Key Changes from Previous Versions
 
-- **No backward compatibility**: This is a clean break from the legacy certificate system
-- **No separate Port80Handler**: ACME challenges are now handled as regular SmartProxy routes
-- **Unified route-based configuration**: Certificates are configured directly in route definitions
+### v19.0.0 Changes
+- **Global ACME configuration**: Set default ACME settings for all routes with `certificate: 'auto'`
+- **Configuration hierarchy**: Top-level ACME settings serve as defaults, route-level settings override
+- **Better error messages**: Clear guidance when ACME configuration is missing
+- **Improved validation**: Configuration validation warns about common issues
+
+### v18.0.0 Changes (from v17)
+- **No backward compatibility**: Clean break from the legacy certificate system
+- **No separate Port80Handler**: ACME challenges handled as regular SmartProxy routes
+- **Unified route-based configuration**: Certificates configured directly in route definitions
 - **Direct integration with @push.rocks/smartacme**: Leverages SmartAcme's built-in capabilities
 
 ## Configuration
 
+### Global ACME Configuration (New in v19+)
+
+Set default ACME settings at the top level that apply to all routes with `certificate: 'auto'`:
+
+```typescript
+const proxy = new SmartProxy({
+  // Global ACME defaults
+  acme: {
+    email: 'ssl@example.com',         // Required for Let's Encrypt
+    useProduction: false,             // Use staging by default
+    port: 80,                         // Port for HTTP-01 challenges
+    renewThresholdDays: 30,           // Renew 30 days before expiry
+    certificateStore: './certs',      // Certificate storage directory
+    autoRenew: true,                  // Enable automatic renewal
+    renewCheckIntervalHours: 24       // Check for renewals daily
+  },
+  
+  routes: [
+    // Routes using certificate: 'auto' will inherit global settings
+    {
+      name: 'website',
+      match: { ports: 443, domains: 'example.com' },
+      action: {
+        type: 'forward',
+        target: { host: 'localhost', port: 8080 },
+        tls: {
+          mode: 'terminate',
+          certificate: 'auto'  // Uses global ACME configuration
+        }
+      }
+    }
+  ]
+});
+```

 ### Route-Level Certificate Configuration
 
 Certificates are now configured at the route level using the `tls` property:

 ```
 
+## Dynamic Route Updates
+
+When routes are updated dynamically using `updateRoutes()`, SmartProxy maintains certificate management continuity:
+
+```typescript
+// Update routes with new domains
+await proxy.updateRoutes([
+  {
+    name: 'new-domain',
+    match: { ports: 443, domains: 'newsite.example.com' },
+    action: {
+      type: 'forward',
+      target: { host: 'localhost', port: 8080 },

+        mode: 'terminate',
+        certificate: 'auto'  // Will use global ACME config
+      }
+    }
+  }
+]);
+```
+
+### Important Notes on Route Updates
+
+1. **Certificate Manager Recreation**: When routes are updated, the certificate manager is recreated to reflect the new configuration
+2. **ACME Callbacks Preserved**: The ACME route update callback is automatically preserved during route updates
+3. **Existing Certificates**: Certificates already provisioned are retained in the certificate store
+4. **New Route Certificates**: New routes with `certificate: 'auto'` will trigger certificate provisioning
+
+### ACME Challenge Route Lifecycle
+
+SmartProxy v19.2.3+ implements an improved challenge route lifecycle to prevent port conflicts:
+
+1. **Single Challenge Route**: The ACME challenge route on port 80 is added once during initialization, not per certificate
+2. **Persistent During Provisioning**: The challenge route remains active throughout the entire certificate provisioning process
+3. **Concurrency Protection**: Certificate provisioning is serialized to prevent race conditions
+4. **Automatic Cleanup**: The challenge route is automatically removed when the certificate manager stops
+
+### Troubleshooting Port 80 Conflicts
+
+If you encounter "EADDRINUSE" errors on port 80:
+
+1. **Check Existing Services**: Ensure no other service is using port 80
+2. **Verify Configuration**: Confirm your ACME configuration specifies the correct port
+3. **Monitor Logs**: Check for "Challenge route already active" messages
+4. **Restart Clean**: If issues persist, restart SmartProxy to reset state
+
+### Route Update Best Practices
+
+1. **Batch Updates**: Update multiple routes in a single `updateRoutes()` call for efficiency
+2. **Monitor Certificate Status**: Check certificate status after route updates
+3. **Handle ACME Errors**: Implement error handling for certificate provisioning failures
+4. **Test Updates**: Test route updates in staging environment first
+5. **Check Port Availability**: Ensure port 80 is available before enabling ACME
+
 ## Best Practices
 
 1. **Always test with staging ACME servers first**
 2. **Set up monitoring for certificate expiration**
 3. **Use meaningful route names for easier certificate management**
 4. **Store static certificates securely with appropriate permissions**
-5. **Implement certificate status monitoring in production**
+5. **Implement certificate status monitoring in production**

+# Port 80 ACME Management in SmartProxy
+
+## Overview
+
+SmartProxy correctly handles port management when both user routes and ACME challenges need to use the same port (typically port 80). This document explains how the system prevents port conflicts and EADDRINUSE errors.
+
+## Port Deduplication
+
+SmartProxy's PortManager implements automatic port deduplication:
+
+```typescript
+public async addPort(port: number): Promise<void> {
+  // Check if we're already listening on this port
+  if (this.servers.has(port)) {
+    console.log(`PortManager: Already listening on port ${port}`);
+    return;
+  }
+  
+  // Create server for this port...
+}
+```
+
+This means that when both a user route and ACME challenges are configured to use port 80, the port is only opened once and shared between both use cases.
+
+## ACME Challenge Route Flow
+
+1. **Initialization**: When SmartProxy starts and detects routes with `certificate: 'auto'`, it initializes the certificate manager
+2. **Challenge Route Creation**: The certificate manager creates a special challenge route on the configured ACME port (default 80)
+3. **Route Update**: The challenge route is added via `updateRoutes()`, which triggers port allocation
+4. **Deduplication**: If port 80 is already in use by a user route, the PortManager's deduplication prevents double allocation
+5. **Shared Access**: Both user routes and ACME challenges share the same port listener
+
+## Configuration Examples
+
+### Shared Port (Recommended)
+
+```typescript
+const settings = {
+  routes: [
+    {
+      name: 'web-traffic',
+      match: {
+        ports: [80]
+      },
+      action: {
+        type: 'forward',
+        targetUrl: 'http://localhost:3000'
+      }
+    },
+    {
+      name: 'secure-traffic',
+      match: {
+        ports: [443]
+      },
+      action: {
+        type: 'forward',
+        targetUrl: 'https://localhost:3001',
+        tls: {
+          mode: 'terminate',
+          certificate: 'auto'
+        }
+      }
+    }
+  ],
+  acme: {
+    email: 'your-email@example.com',
+    port: 80  // Same as user route - this is safe!
+  }
+};
+```
+
+### Separate ACME Port
+
+```typescript
+const settings = {
+  routes: [
+    {
+      name: 'web-traffic',
+      match: {
+        ports: [80]
+      },
+      action: {
+        type: 'forward',
+        targetUrl: 'http://localhost:3000'
+      }
+    }
+  ],
+  acme: {
+    email: 'your-email@example.com',
+    port: 8080  // Different port for ACME challenges
+  }
+};
+```
+
+## Best Practices
+
+1. **Use Default Port 80**: Let ACME use port 80 (the default) even if you have user routes on that port
+2. **Priority Routing**: ACME challenge routes have high priority (1000) to ensure they take precedence
+3. **Path-Based Routing**: ACME routes only match `/.well-known/acme-challenge/*` paths, avoiding conflicts
+4. **Automatic Cleanup**: Challenge routes are automatically removed when not needed
+
+## Troubleshooting
+
+### EADDRINUSE Errors
+
+If you see EADDRINUSE errors, check:
+
+1. Is another process using the port?
+2. Are you running multiple SmartProxy instances?
+3. Is the previous instance still shutting down?
+
+### Certificate Provisioning Issues
+
+1. Ensure the ACME port is accessible from the internet
+2. Check that DNS is properly configured for your domains
+3. Verify email configuration in ACME settings
+
+## Technical Details
+
+The port deduplication is handled at multiple levels:
+
+1. **PortManager Level**: Checks if port is already active before creating new listener
+2. **RouteManager Level**: Tracks which ports are needed and updates accordingly
+3. **Certificate Manager Level**: Adds challenge route only when needed
+
+This multi-level approach ensures robust port management without conflicts.

+- Maintained support for route-level ACME configuration
+- Implemented configuration hierarchy where global settings serve as defaults
+- Route-level settings override global defaults when specified
+
+### 2. Updated Core Components
+
+#### SmartProxy Class (`smart-proxy.ts`)
+- Enhanced ACME configuration normalization in constructor
+- Added support for both `email` and `accountEmail` fields
+- Updated `initializeCertificateManager` to prioritize configurations correctly
+- Added `validateAcmeConfiguration` method for comprehensive validation
+
+#### SmartCertManager Class (`certificate-manager.ts`)
+- Added `globalAcmeDefaults` property to store top-level configuration
+- Implemented `setGlobalAcmeDefaults` method
+- Updated `provisionAcmeCertificate` to use global defaults
+- Enhanced error messages to guide users to correct configuration
+
+#### ISmartProxyOptions Interface (`interfaces.ts`)
+- Added comprehensive documentation for global ACME configuration
+- Enhanced IAcmeOptions interface with better field descriptions
+- Added example usage in JSDoc comments
+
+### 3. Configuration Validation
+- Checks for missing ACME email configuration
+- Validates port 80 availability for HTTP-01 challenges
+- Warns about wildcard domains with auto certificates
+- Detects environment mismatches between global and route configs
+
+### 4. Test Coverage
+Created comprehensive test suite (`test.acme-configuration.node.ts`):
+- Top-level ACME configuration
+- Route-level ACME configuration
+- Mixed configuration with overrides
+- Error handling for missing email
+- Support for accountEmail alias
+
+### 5. Documentation Updates
+
+#### Main README (`readme.md`)
+- Added global ACME configuration example
+- Updated code examples to show both configuration styles
+- Added dedicated ACME configuration section
+
+#### Certificate Management Guide (`certificate-management.md`)
+- Updated for v19.0.0 changes
+- Added configuration hierarchy explanation
+- Included troubleshooting section
+- Added migration guide from v18
+
+#### Readme Hints (`readme.hints.md`)
+- Added breaking change warning for ACME configuration
+- Included correct configuration example
+- Added migration considerations
+
+## Key Benefits
+
+1. **Reduced Configuration Duplication**: Global ACME settings eliminate need to repeat configuration
+2. **Better Developer Experience**: Clear error messages guide users to correct configuration
+3. **Backward Compatibility**: Route-level configuration still works as before
+4. **Flexible Configuration**: Can mix global defaults with route-specific overrides
+5. **Improved Validation**: Warns about common configuration issues
+
+## Testing Results
+
+All tests pass successfully:
+- Global ACME configuration works correctly
+- Route-level configuration continues to function
+- Configuration hierarchy behaves as expected
+- Error messages provide clear guidance
+
+## Migration Path
+
+For users upgrading from v18:
+1. Existing route-level ACME configuration continues to work
+2. Can optionally move common settings to global level
+3. Route-specific overrides remain available
+4. No breaking changes for existing configurations
+
+## Conclusion
+
+The implementation successfully addresses the original issue where SmartAcme was not initialized due to missing configuration. Users now have flexible options for configuring ACME, with clear error messages and comprehensive documentation to guide them.
