# SmartProxy Complete Route-Based Implementation Plan
# Enhanced NetworkProxy with Native Route-Based Configuration
## Project Goal
Complete the refactoring of SmartProxy to a pure route-based configuration approach by:
1. Removing all remaining domain-based configuration code with no backward compatibility
2. Updating internal components to work directly and exclusively with route configurations
3. Eliminating all conversion functions and domain-based interfaces
4. Cleaning up deprecated methods and interfaces completely
5. Focusing entirely on route-based helper functions for the best developer experience
Transform NetworkProxy to natively use route-based configurations (`IRouteConfig`) as its primary configuration format, completely eliminating translation layers while maintaining backward compatibility through adapter methods for existing code.
## Current Status
The major refactoring to route-based configuration has been successfully completed:
- SmartProxy now works exclusively with route-based configurations in its public API
- All test files have been updated to use route-based configurations
- Documentation has been updated to explain the route-based approach
- Helper functions have been implemented for creating route configurations
- All features are working correctly with the new approach
### Completed Phases:
1. ✅ **Phase 1:** CertProvisioner has been fully refactored to work natively with routes
2. ✅ **Phase 2:** NetworkProxyBridge now works directly with route configurations
3. ✅ **Phase 3:** Legacy domain configuration code has been removed
4. ✅ **Phase 4:** Route helpers and configuration experience have been enhanced
5. ✅ **Phase 5:** Tests and validation have been completed
The current implementation uses:
- SmartProxy has a rich `IRouteConfig` format with match/action pattern
- NetworkProxy uses a simpler `IReverseProxyConfig` focused on hostname and destination
- `NetworkProxyBridge` translates between these formats, losing information
- Dynamic function-based hosts and ports aren't supported in NetworkProxy
- Duplicate configuration logic exists across components

- [x] 7.4 Remove all legacy NetworkProxyBridge conversion code
- [x] 7.5 Make the NetworkProxyBridge a pure proxy pass-through component
- [x] 7.6 Standardize event naming and handling across components
To keep our codebase as clean as possible, we are taking a clean break approach with NO migration or compatibility support for domain-based configuration. We will:
### Phase 8: Certificate Management Consolidation
- [x] 8.1 Create a unified CertificateManager component
- [x] 8.2 Centralize certificate storage and renewal logic
- [x] 8.3 Simplify ACME challenge handling across proxies
- [x] 8.4 Implement shared certificate events for all components
- [x] 8.5 Remove redundant certificate synchronization logic
- [x] 8.6 Standardize SNI handling between different proxies
1. Completely remove all domain-based code
2. Not provide any migration utilities in the codebase
3. Focus solely on the route-based approach
4. Document the route-based API as the only supported method
### Phase 9: Context and Configuration Standardization
- [x] 9.1 Implement a single shared IRouteContext class
- [x] 9.2 Remove all duplicate context creation logic
- [x] 9.3 Standardize option interfaces across components
- [x] 9.4 Create shared default configurations
- [x] 9.5 Implement a unified configuration validation system
- [x] 9.6 Add runtime type checking for configurations
This approach prioritizes codebase clarity over backward compatibility, which is appropriate since we've already made a clean break in the public API with v14.0.0.
### Phase 10: Component Consolidation
- [x] 10.1 Merge SmartProxy and NetworkProxy functionality where appropriate
- [x] 10.2 Create a unified connection pool management system
- [x] 10.3 Standardize timeout handling across components
- [x] 10.4 Implement shared logging and monitoring
- [x] 10.5 Remove all deprecated methods and legacy compatibility
- [x] 10.6 Reduce API surface area to essentials
## File Changes
### Phase 11: Performance Optimization & Advanced Features
- [ ] 11.1 Conduct comprehensive performance benchmarking
- [ ] 11.2 Optimize memory usage in high-connection scenarios
- [ ] 11.3 Implement connection pooling for backend targets
- [ ] 11.4 Add support for HTTP/3 and QUIC protocols
- [ ] 11.5 Enhance WebSocket support with compression and multiplexing
- [ ] 11.6 Add advanced observability through metrics and tracing integration
### Files to Delete (Remove Completely)
- [x] `/ts/forwarding/config/domain-config.ts` - Deleted with no replacement
- [x] `/ts/forwarding/config/domain-manager.ts` - Deleted with no replacement
- [x] `/ts/forwarding/config/forwarding-types.ts` - Updated with pure route-based types

## Benefits of Simplified Architecture
### Files to Modify (Remove All Domain References)
- [x] `/ts/certificate/providers/cert-provisioner.ts` - Complete rewrite to use routes only ✅
- [x] `/ts/proxies/smart-proxy/network-proxy-bridge.ts` - Direct route processing implementation ✅
- [x] `/ts/certificate/models/certificate-types.ts` - Updated with route-based interfaces ✅
- [x] `/ts/certificate/index.ts` - Cleaned up domain-related types and exports
- [x] `/ts/http/port80/port80-handler.ts` - Updated to work exclusively with routes
- [x] `/ts/proxies/smart-proxy/smart-proxy.ts` - Removed domain references
- [x] `test/test.forwarding.ts` - Updated to use route-based approach
- [x] `test/test.forwarding.unit.ts` - Updated to use route-based approach
1. **Reduced Duplication**:
- Shared route processing logic
- Single certificate management system
- Unified context objects
### New Files to Create (Route-Focused)
- [x] `/ts/proxies/smart-proxy/utils/route-helpers.ts` - Created with helper functions for common route configurations
- [x] `/ts/proxies/smart-proxy/utils/route-migration-utils.ts` - Added migration utilities from domains to routes
- [x] `/ts/proxies/smart-proxy/utils/route-validators.ts` - Validation utilities for route configurations
- [x] `/ts/proxies/smart-proxy/utils/route-utils.ts` - Additional route utility functions
- [x] `/ts/proxies/smart-proxy/utils/route-patterns.ts` - Common route patterns for easy configuration
- [x] `/ts/proxies/smart-proxy/utils/index.ts` - Central export point for all route utilities
2. **Simplified Codebase**:
- Fewer managers with cleaner responsibilities
- Consistent APIs across components
- Reduced complexity in bridge components
## Benefits of Complete Refactoring
3. **Improved Maintainability**:
- Easier to understand component relationships
- Consolidated logic for critical operations
- Clearer separation of concerns
1. **Codebase Simplicity**:
- No dual implementation or conversion logic
- Simplified mental model for developers
- Easier to maintain and extend
4. **Enhanced Performance**:
- Less overhead in communication between components
- Reduced memory usage through shared objects
- More efficient request processing
2. **Performance Improvements**:
- Remove conversion overhead
- More efficient route matching
- Reduced memory footprint
5. **Better Developer Experience**:
- Consistent conceptual model across system
- More intuitive configuration interface
- Simplified debugging and troubleshooting
3. **Better Developer Experience**:
- Consistent API throughout
- Cleaner documentation
- More intuitive configuration patterns
## Implementation Approach
4. **Future-Proof Design**:
- Clear foundation for new features
- Easier to implement advanced routing capabilities
- Better integration with modern web patterns
The implementation of phases 7-10 will focus on gradually consolidating duplicate functionality:
1. First, implement shared managers and utilities to be used by both proxies
2. Then consolidate certificate management to simplify ACME handling
3. Create standardized context objects and configurations
4. Finally, merge overlapping functionality between proxy components
This approach will maintain compatibility with existing code while progressively simplifying the architecture to reduce complexity and improve performance.
