# Changelog
## 2025-05-09 - 12.2.0 - feat(acme)
Add ACME interfaces for Port80Handler and refactor ChallengeResponder to use new acme-interfaces, enhancing event subscription and certificate workflows.
- Introduce new file ts/http/port80/acme-interfaces.ts defining SmartAcme interfaces, ICertManager, Http01MemoryHandler, and related types.
- Refactor ts/http/port80/challenge-responder.ts to import types from acme-interfaces and improve event forwarding for certificate events.
- Update readme.plan.md to reflect migration of Port80Handler and addition of ACME interfaces.
## 2025-05-09 - 12.1.0 - feat(smartproxy)
Migrate internal module paths and update HTTP/ACME components for SmartProxy
- Mark migration tasks as complete in readme.plan.md (checkboxes updated to ✅)
- Moved Port80Handler from ts/port80handler to ts/http/port80 (and extracted challenge responder)
- Migrated redirect handlers and router components to ts/http/redirects and ts/http/router respectively
- Updated re-exports in ts/index.ts and ts/plugins.ts to expose new module paths and additional exports
- Refactored CertificateEvents to include deprecation notes on Port80HandlerEvents
- Adjusted internal module organization for TLS, ACME, and forwarding (SNI extraction, client-hello parsing, etc.)
- Added minor logging and formatting improvements in several modules
## 2025-05-09 - 12.0.0 - BREAKING CHANGE(forwarding)
Rename 'sniPassthrough' export to 'httpsPassthrough' for consistent naming and remove outdated forwarding example
- Updated test files (test.forwarding.ts and test.forwarding.unit.ts) to reference 'httpsPassthrough' instead of the old alias 'sniPassthrough'
- Modified ts/smartproxy/forwarding/index.ts to export 'httpsPassthrough' without the legacy alias
- Removed ts/examples/forwarding-example.ts to clean up redundant example code
## 2025-05-09 - 11.0.0 - BREAKING CHANGE(forwarding)
Refactor unified forwarding API and remove redundant documentation. Removed docs/forwarding-system.md (its content is migrated into readme.md) and updated helper functions (e.g. replacing sniPassthrough with httpsPassthrough) to accept configuration objects. Legacy fields in domain configurations (allowedIPs, blockedIPs, useNetworkProxy, networkProxyPort, connectionTimeout) have been removed in favor of forwarding.security and advanced options. Tests and examples have been updated accordingly.
- Removed docs/forwarding-system.md; forwarding system docs now reside in readme.md.
- Updated helper functions (httpOnly, tlsTerminateToHttp, tlsTerminateToHttps, httpsPassthrough) to accept object parameters rather than individual arguments.
- Removed legacy domain configuration properties, shifting IP filtering to the forwarding.security field.
- Adjusted return types and API contracts for certificate provisioning and SNI handling in the unified forwarding system.
- Updated tests and examples to align with the new configuration interface.
## 2025-05-09 - 10.3.0 - feat(forwarding)
Add unified forwarding system docs and tests; update build script and .gitignore
- Added docs/forwarding-system.md documenting the new unified forwarding system architecture, configuration, and usage examples
- Updated .gitignore to exclude .claude/ directory
- Modified package.json build script from 'tsbuild --web --allowimplicitany' to 'tsbuild tsfolders --allowimplicitany'
- Extended ts/index.ts export to include the forwarding module
- Introduced new tests and unit tests for forwarding, network proxy, and certificate provisioning
## 2025-05-05 - 10.2.0 - feat(CertificateManager)
Implement on-demand certificate retrieval for missing SNI certificates. When no certificate is found for a TLS ClientHello, the system now automatically registers the domain with the Port80Handler to trigger ACME issuance and immediately falls back to using the default certificate to complete the handshake. Additionally, HTTP requests on port 80 for unrecognized domains now return a 503 indicating that certificate issuance is in progress.
- In CertificateManager.handleSNI, if no certificate is cached, call port80Handler.addDomain to trigger on-demand provisioning.
- Update Port80Handler.handleRequest to register unknown domains and return a 503 for ACME HTTP-01 challenge requests.
- Emit observability events (e.g. certificateRequested) so dynamic certificate requests can be tracked.
- Fallback to default SSL context to allow TLS handshake while certificate issuance is performed.
- Update and extend unit and integration tests to verify the new on-demand certificate flow.
## 2025-05-05 - 10.1.0 - feat(smartproxy)
Implement fallback to NetworkProxy on missing SNI and rename certProvider to certProvisionFunction in CertProvisioner
- When a TLS ClientHello is received without an SNI extension and allowSessionTicket is false, the code now attempts to forward the connection to NetworkProxy instead of immediately closing the connection with a TLS alert.
- An error callback has been added to handle proxy forwarding failures; if forwarding fails or no NetworkProxy is available, the TLS unrecognized_name alert is sent and the connection is terminated.
- Renamed all instances of 'certProvider' to 'certProvisionFunction' in the CertProvisioner implementation, updating the associated types and call sites.
- Updated unit tests to simulate a ClientHello without SNI and to verify that with NetworkProxy enabled the connection is correctly forwarded.
## 2025-05-05 - 10.0.12 - fix(port80handler)
refactor ACME challenge handling to use dedicated Http01MemoryHandler, remove obsolete readme.plan.md, and update version to 10.0.12
- Removed readme.plan.md planning document
- Eliminated internal acmeHttp01Storage from Port80Handler
- Instantiated and integrated Http01MemoryHandler as a class property for managing HTTP-01 challenges
- Delegated ACME HTTP-01 challenge responses to smartAcmeHttp01Handler
- Updated ts/00_commitinfo_data.ts version from 10.0.11 to 10.0.12
- Adjusted certificate provisioning logic to properly handle wildcard domains and on-demand requests
## 2025-05-05 - 10.0.12 - fix(port80handler)
Remove obsolete readme.plan.md and refactor Port80Handler's ACME challenge handling to use a dedicated Http01MemoryHandler
- Deleted readme.plan.md planning document which was no longer needed
- Removed internal acmeHttp01Storage map from Port80Handler
- Instantiated Http01MemoryHandler as a class property and provided it to SmartAcme for challenge handling
- Delegated ACME HTTP-01 challenge responses to the new smartAcmeHttp01Handler instead of in-memory storage
## 2025-05-05 - 10.0.11 - fix(dependencies)
Bump @push.rocks/smartacme to ^7.2.5 and @tsclass/tsclass to ^9.2.0; update MemoryCertManager import to use plugins.smartacme.certmanagers.MemoryCertManager()
- Updated @push.rocks/smartacme from ^7.2.4 to ^7.2.5
- Updated @tsclass/tsclass from ^9.1.0 to ^9.2.0
- Refactored MemoryCertManager instantiation to use the new import path
## 2025-05-05 - 10.0.10 - fix(docs)
Update README: rename certProviderFunction to certProvisionFunction in configuration options for consistency.
- Replaced 'certProviderFunction' with 'certProvisionFunction' in the docs to reflect the updated API.
- Ensured all references in the readme are consistent with the new naming convention.
## 2025-05-05 - 10.0.9 - fix(documentation)
Update documentation to use 'certProviderFunction' instead of 'certProvider' in SmartProxy settings.
- Renamed 'certProvider' to 'certProviderFunction' in README examples and configuration options.
- Ensured consistency in the configuration section of the documentation.
## 2025-05-05 - 10.0.8 - fix(smartproxy)

- In ts/smartproxy/classes.pp.interfaces.ts, renamed the optional property 'certProvider' to 'certProvisionFunction'.
- In ts/smartproxy/classes.smartproxy.ts, updated references from this.settings.certProvider to this.settings.certProvisionFunction.
## 2025-05-04 - 10.0.7 - fix(core)

- Replaced IPortProxySettings with ISmartProxyOptions in connection handler, connection manager, domain config manager, security manager, timeout manager, TLS manager, and network proxy bridge.
- Updated type imports and constructors accordingly while preserving backward compatibility via export alias.
## 2025-05-04 - 10.0.6 - fix(smartproxy)

Provide a `certProvisionFunction(domain)` in SmartProxy settings to supply static certs or return `'http01'`.
## Unified Forwarding System
The SmartProxy Unified Forwarding System provides a clean, use-case driven approach to configuring different types of traffic forwarding. It replaces disparate configuration mechanisms with a unified interface.
### Forwarding Types
The system supports four primary forwarding types:
1. **HTTP-only (`http-only`)**: Forwards HTTP traffic to a backend server.
2. **HTTPS Passthrough (`https-passthrough`)**: Passes through raw TLS traffic without termination (SNI forwarding).
3. **HTTPS Termination to HTTP (`https-terminate-to-http`)**: Terminates TLS and forwards the decrypted traffic to an HTTP backend.
4. **HTTPS Termination to HTTPS (`https-terminate-to-https`)**: Terminates TLS and creates a new TLS connection to an HTTPS backend.
### Basic Configuration
Each domain is configured with a forwarding type and target:
```typescript
{
domains: ['example.com'],
forwarding: {
type: 'http-only',
target: {
host: 'localhost',
port: 3000
}
}
}
```
### Helper Functions
Helper functions are provided for common configurations:
```typescript
import { createDomainConfig, httpOnly, tlsTerminateToHttp,
tlsTerminateToHttps, httpsPassthrough } from '@push.rocks/smartproxy';
// HTTP-only
await domainManager.addDomainConfig(
createDomainConfig('example.com', httpOnly({
target: { host: 'localhost', port: 3000 }
}))
);
// HTTPS termination to HTTP
await domainManager.addDomainConfig(
createDomainConfig('secure.example.com', tlsTerminateToHttp({
target: { host: 'localhost', port: 3000 },
acme: { production: true }
}))
);
// HTTPS termination to HTTPS
await domainManager.addDomainConfig(
createDomainConfig('api.example.com', tlsTerminateToHttps({
target: { host: 'internal-api', port: 8443 },
http: { redirectToHttps: true }
}))
);
// HTTPS passthrough (SNI)
await domainManager.addDomainConfig(
createDomainConfig('passthrough.example.com', httpsPassthrough({
target: { host: '10.0.0.5', port: 443 }
}))
);
```
### Advanced Configuration
For more complex scenarios, additional options can be specified:
```typescript
{
domains: ['api.example.com'],
forwarding: {
type: 'https-terminate-to-https',
target: {
host: ['10.0.0.10', '10.0.0.11'], // Round-robin load balancing
port: 8443
},
http: {
enabled: true,
redirectToHttps: true
},
https: {
// Custom certificate instead of ACME-provisioned
customCert: {
key: '-----BEGIN PRIVATE KEY-----\n...',
cert: '-----BEGIN CERTIFICATE-----\n...'
}
},
security: {
allowedIps: ['10.0.0.*', '192.168.1.*'],
blockedIps: ['1.2.3.4'],
maxConnections: 100
},
advanced: {
timeout: 30000,
headers: {
'X-Forwarded-For': '{clientIp}',
'X-Original-Host': '{sni}'
}
}
}
}
```
### Extended Configuration Options
#### IForwardConfig
- `type`: 'http-only' | 'https-passthrough' | 'https-terminate-to-http' | 'https-terminate-to-https'
- `target`: { host: string | string[], port: number }
- `http?`: { enabled?: boolean, redirectToHttps?: boolean, headers?: Record<string, string> }

# Project Simplification Plan
# SmartProxy Project Restructuring Plan
This document outlines a roadmap to simplify and refactor the SmartProxy & NetworkProxy codebase for better maintainability, reduced duplication, and clearer configuration.
## Project Goal
Reorganize the SmartProxy codebase to improve maintainability, readability, and developer experience through:
1. Standardized naming conventions
2. Consistent directory structure
3. Modern TypeScript patterns
4. Clear separation of concerns
## Goals
- Eliminate duplicate code and shared types
- Unify certificate management flow across components
- Simplify configuration schemas and option handling
- Centralize plugin imports and module interfaces
- Strengthen type safety and linting
- Improve test coverage and CI integration
## Current Architecture Analysis
## Plan
- [x] Extract all shared interfaces and types (e.g., certificate, proxy, domain configs) into a common `ts/common` module
- [x] Consolidate ACME/Port80Handler logic:
- [x] Merge standalone Port80Handler into a single certificate service
- [x] Remove duplicate ACME setup in SmartProxy and NetworkProxy
- [x] Unify configuration options:
- [x] Merge `INetworkProxyOptions.acme`, `IPort80HandlerOptions`, and `port80HandlerConfig` into one schema
- [x] Deprecate old option names and provide clear upgrade path
- [x] Centralize plugin imports in `ts/plugins.ts` and update all modules to use it
- [x] Remove legacy or unused code paths (e.g., old HTTP/2 fallback logic if obsolete)
- [ ] Enhance and expand test coverage:
- Add unit tests for certificate issuance, renewal, and error handling
- Add integration tests for HTTP challenge routing and request forwarding
- [ ] Update main README.md with architecture overview and configuration guide
- [ ] Review and prune external dependencies no longer needed
Based on code analysis, SmartProxy has several well-defined but inconsistently named modules:
Once these steps are complete, the project will be cleaner, easier to understand, and simpler to extend.
1. **SmartProxy** - Primary TCP/SNI-based proxy with configurable routing
2. **NetworkProxy** - HTTP/HTTPS reverse proxy with TLS termination
3. **Port80Handler** - HTTP port 80 handling for ACME and redirects
4. **NfTablesProxy** - Low-level port forwarding via nftables
5. **Forwarding System** - New unified configuration for all forwarding types
The codebase employs several strong design patterns:
- **Factory Pattern** for creating forwarding handlers
- **Strategy Pattern** for implementing different forwarding methods
- **Manager Pattern** for encapsulating domain, connection, and security logic
- **Event-Driven Architecture** for loose coupling between components

## Import Strategy
Since path aliases will not be used, we'll maintain standard relative imports throughout the codebase:
1. **Import Strategy for Deeply Nested Files**
```typescript
// Example: Importing from another component in a nested directory
// From ts/forwarding/handlers/http-handler.ts to ts/core/utils/validation-utils.ts
import { validateConfig } from '../../../core/utils/validation-utils.js';
```
2. **Barrel Files for Convenience**
```typescript
// ts/forwarding/index.ts
export * from './config/forwarding-types.js';
export * from './handlers/base-handler.js';
// ... other exports
// Then in consuming code:
import { ForwardingHandler, httpOnly } from '../../forwarding/index.js';
```
3. **Flattened Imports Where Sensible**
```typescript
// Avoid excessive nesting with targeted exports
// ts/index.ts will export key components for external use
import { SmartProxy, NetworkProxy } from '../index.js';
```
## Expected Outcomes
### Improved Code Organization
- Related code will be grouped together in domain-specific directories
- Consistent naming conventions will make code navigation intuitive
- Clear module boundaries will prevent unintended dependencies
### Enhanced Developer Experience
- Standardized interface naming will improve type clarity
- Better documentation will help new contributors get started
- Clear and predictable file locations
### Maintainability Benefits
- Smaller, focused files with clear responsibilities
- Unified patterns for common operations
- Improved separation of concerns between components
- Better test organization matching source structure
### Performance and Compatibility
- No performance regression from structural changes
- Backward compatibility through type aliases and consistent exports
- Clear migration path for dependent projects
## Migration Strategy
To ensure a smooth transition, we'll follow this approach for each component:
1. Create the new file structure first
2. Migrate code while updating relative imports
3. Test each component as it's migrated
4. Only remove old files once all dependencies are updated
5. Use a phased approach to allow parallel work
This approach ensures the codebase remains functional throughout the restructuring process while progressively adopting the new organization.
## Measuring Success
We'll measure the success of this restructuring by:
1. Reduced complexity in the directory structure
2. Improved code coverage through better test organization
3. Faster onboarding time for new developers
4. Less time spent navigating the codebase
5. Cleaner git blame output showing cohesive component changes
## Special Considerations
- We'll maintain backward compatibility for all public APIs
- We'll provide detailed upgrade guides for any breaking changes
- We'll ensure the build process produces compatible output
- We'll preserve commit history using git move operations where possible
