# Changelog
## 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()

# SmartProxy Unified Forwarding System
This document describes the new unified forwarding system in SmartProxy.
## Overview
The forwarding system provides a clean, use-case driven approach to configuring different types of traffic forwarding. It replaces the previous 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.
## Configuration
### 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 { helpers } from '../smartproxy/forwarding/index.js';
// HTTP-only
const httpConfig = helpers.httpOnly('localhost', 3000);
// HTTPS termination to HTTP
const terminateToHttpConfig = helpers.tlsTerminateToHttp('localhost', 3000);
// HTTPS termination to HTTPS
const terminateToHttpsConfig = helpers.tlsTerminateToHttps('localhost', 8443);
// HTTPS passthrough (SNI)
const passthroughConfig = helpers.sniPassthrough('localhost', 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}'
}
}
}
}
```
## DomainManager
The `DomainManager` class manages domains and their forwarding handlers:
```typescript
import { DomainManager, createDomainConfig, helpers } from '../smartproxy/forwarding/index.js';
// Create the domain manager
const domainManager = new DomainManager();
// Add a domain
await domainManager.addDomainConfig(
createDomainConfig('example.com', helpers.httpOnly('localhost', 3000))
);
// Handle a connection
domainManager.handleConnection('example.com', socket);
// Handle an HTTP request
domainManager.handleHttpRequest('example.com', req, res);
```
## Usage Examples
### Basic HTTP Server
```typescript
{
domains: ['example.com'],
forwarding: {
type: 'http-only',
target: {
host: 'localhost',
port: 3000
}
}
}
```
### HTTPS Termination with HTTP Backend
```typescript
{
domains: ['secure.example.com'],
forwarding: {
type: 'https-terminate-to-http',
target: {
host: 'localhost',
port: 3000
},
acme: {
production: true // Use production Let's Encrypt
}
}
}
```
### HTTPS Termination with HTTPS Backend
```typescript
{
domains: ['secure-backend.example.com'],
forwarding: {
type: 'https-terminate-to-https',
target: {
host: 'internal-api',
port: 8443
},
http: {
redirectToHttps: true // Redirect HTTP requests to HTTPS
}
}
}
```
### SNI Passthrough
```typescript
{
domains: ['passthrough.example.com'],
forwarding: {
type: 'https-passthrough',
target: {
host: '10.0.0.5',
port: 443
}
}
}
```
### Load Balancing
```typescript
{
domains: ['api.example.com'],
forwarding: {
type: 'https-terminate-to-https',
target: {
host: ['10.0.0.10', '10.0.0.11', '10.0.0.12'], // Round-robin
port: 8443
}
}
}
```
## Integration with SmartProxy
The unified forwarding system integrates with SmartProxy by replacing the existing domain configuration mechanism. The `DomainManager` handles all domain matching and forwarding, while the individual forwarding handlers handle the connections and requests.
The system is designed to be used in SmartProxy's `ConnectionHandler` and in the `Port80Handler` for HTTP traffic.
## Testing
See the `test.forwarding.ts` file for examples of how to test the forwarding system.
## Migration
When migrating from the older configuration system, map the existing configuration to the appropriate forwarding type:
1. HTTP forwarding → `http-only`
2. SNI forwarding → `https-passthrough`
3. NetworkProxy with HTTP backend → `https-terminate-to-http`
4. NetworkProxy with HTTPS backend → `https-terminate-to-https`
## Extensibility
The forwarding system is designed to be extensible:
1. New forwarding types can be added by:
- Adding a new type to `ForwardingType`
- Creating a new handler class
- Adding the handler to `ForwardingHandlerFactory`
2. Existing types can be extended with new options by updating the interface and handler implementations.
## Implementation Details
The system uses a factory pattern to create the appropriate handler for each forwarding type. Each handler extends a base `ForwardingHandler` class that provides common functionality.
The `DomainManager` manages the domains and their handlers, and delegates connections and requests to the appropriate handler.
## Performance Considerations
- The system uses a map for fast domain lookups
- Wildcard domains are supported through pattern matching
- Handlers are reused for multiple domains with the same configuration

## Quick Start
### 1. HTTP(S) Reverse Proxy (NetworkProxy)
```typescript
import { NetworkProxy } from '@push.rocks/smartproxy';
const proxy = new NetworkProxy({ port: 443 });
await proxy.start();
await proxy.updateProxyConfigs([
{
hostName: 'example.com',
destinationIps: ['127.0.0.1'],
destinationPorts: [3000],
publicKey: fs.readFileSync('cert.pem', 'utf8'),
privateKey: fs.readFileSync('key.pem', 'utf8'),
}
]);
// Add default headers to all responses
await proxy.addDefaultHeaders({
'Strict-Transport-Security': 'max-age=31536000; includeSubDomains'
});
// ...
await proxy.stop();
```
### 2. HTTP→HTTPS Redirect (Redirect / SslRedirect)
```typescript
import { Redirect, SslRedirect } from '@push.rocks/smartproxy';
import * as fs from 'fs';
// Custom redirect rules
const redirect = new Redirect({
httpPort: 80,
httpsPort: 443,
sslOptions: {
key: fs.readFileSync('key.pem'),
cert: fs.readFileSync('cert.pem'),
},
rules: [
{
fromProtocol: 'http',
fromHost: '*',
toProtocol: 'https',
toHost: '$1',
statusCode: 301
}
]
});
await redirect.start();
// Quick HTTP→HTTPS helper on port 80
const quick = new SslRedirect(80);
await quick.start();
```
### 3. Automatic Certificates (ACME Port80Handler)
```typescript
import { Port80Handler } from '@push.rocks/smartproxy';
// Configure ACME on port 80 with contact email
const acme = new Port80Handler({
port: 80,
contactEmail: 'admin@example.com',
useProduction: true,
renewThresholdDays: 30
});
acme.on('certificate-issued', evt => {
console.log(`Certificate ready for ${evt.domain}, expires ${evt.expiryDate}`);
});
await acme.start();
acme.addDomain({
domainName: 'example.com',
sslRedirect: true,
acmeMaintenance: true
});
```
### 4. Low-Level Port Forwarding (NfTablesProxy)
```typescript
import { NfTablesProxy } from '@push.rocks/smartproxy';
// Forward port 80→8080 with source IP preservation
const nft = new NfTablesProxy({
fromPort: 80,
toPort: 8080,
toHost: 'localhost',
preserveSourceIP: true,
deleteOnExit: true
});
await nft.start();
// ...
await nft.stop();
```
### 5. TCP/SNI Proxy (SmartProxy)
```typescript
import { SmartProxy } from '@push.rocks/smartproxy';

{
domains: ['example.com', '*.example.com'],
allowedIPs: ['*'],
targetIPs: ['127.0.0.1'],
}
],
sniEnabled: true
});
smart.on('certificate', evt => console.log(evt));
await smart.start();
// Update domains later
await smart.updateDomainConfigs([/* new configs */]);
```
### 6. SNI Utilities (SniHandler)
```js
import { SniHandler } from '@push.rocks/smartproxy';
// Extract SNI from a TLS ClientHello buffer
const sni = SniHandler.extractSNI(buffer);

## Features
- **HTTPS Reverse Proxy** - Route traffic to backend services based on hostname with TLS termination
- **WebSocket Support** - Full WebSocket proxying with heartbeat monitoring
- **TCP Connection Handling** - Advanced connection handling with SNI inspection and domain-based routing
- **Enhanced TLS Handling** - Robust TLS handshake processing with improved certificate error handling
- **HTTP to HTTPS Redirection** - Automatically redirect HTTP requests to HTTPS
- **Let's Encrypt Integration** - Automatic certificate management using ACME protocol
- **IP Filtering** - Control access with IP allow/block lists using glob patterns
- **NfTables Integration** - Direct manipulation of nftables for advanced low-level port forwarding
- HTTP/HTTPS Reverse Proxy (NetworkProxy)
• TLS termination, virtual-host routing, HTTP/2 & WebSocket support, pooling & metrics
## Certificate Provider Hook & Events
- Automatic ACME Certificates (Port80Handler)
• HTTP-01 challenge handling, certificate issuance/renewal, pluggable storage
You can customize how certificates are provisioned per domain by using the `certProvider` callback and listen for certificate events emitted by `SmartProxy`.
- Low-Level Port Forwarding (NfTablesProxy)
• nftables NAT rules for ports/ranges, IPv4/IPv6, IP filtering, QoS & ipset support
```typescript
import { SmartProxy } from '@push.rocks/smartproxy';
import * as fs from 'fs';
- Custom Redirects (Redirect / SslRedirect)
• URL redirects with wildcard host/path, template variables & status codes
// Example certProvider: static for a specific domain, HTTP-01 otherwise
const certProvider = async (domain: string) => {
if (domain === 'static.example.com') {
// Load from disk or vault
return {
id: 'static-cert',
domainName: domain,
created: Date.now(),
validUntil: Date.now() + 90 * 24 * 60 * 60 * 1000,
privateKey: fs.readFileSync('/etc/ssl/private/static.key', 'utf8'),
publicKey: fs.readFileSync('/etc/ssl/certs/static.crt', 'utf8'),
csr: ''
};
}
// Fallback to ACME HTTP-01 challenge
return 'http01';
};
- TCP/SNI Proxy (SmartProxy)
• SNI-based routing, IP allow/block lists, port ranges, timeouts & graceful shutdown
const proxy = new SmartProxy({
fromPort: 80,
toPort: 8080,
domainConfigs: [{
domains: ['static.example.com', 'dynamic.example.com'],
allowedIPs: ['*']
}],
certProvider
});
- SNI Utilities (SniHandler)
• Robust ClientHello parsing, fragmentation & session resumption support
// Listen for certificate issuance or renewal
proxy.on('certificate', (evt) => {
console.log(`Certificate for ${evt.domain} ready, expires on ${evt.expiryDate}`);
});
## Certificate Hooks & Events
await proxy.start();
```
Listen for certificate events via EventEmitter:
- **Port80Handler**:
- `certificate-issued`, `certificate-renewed`, `certificate-failed`
- `manager-started`, `manager-stopped`, `request-forwarded`
- **SmartProxy**:
- `certificate` (domain, publicKey, privateKey, expiryDate, source, isRenewal)
Provide a `certProvisionFunction(domain)` in SmartProxy settings to supply static certs or return `'http01'`.
## Configuration Options
### backendProtocol
### NetworkProxy (INetworkProxyOptions)
- `port` (number, required)
- `backendProtocol` ('http1'|'http2', default 'http1')
- `maxConnections` (number, default 10000)
- `keepAliveTimeout` (ms, default 120000)
- `headersTimeout` (ms, default 60000)
- `cors` (object)
- `connectionPoolSize` (number, default 50)
- `logLevel` ('error'|'warn'|'info'|'debug')
- `acme` (IAcmeOptions)
- `useExternalPort80Handler` (boolean)
- `portProxyIntegration` (boolean)
Type: 'http1' | 'http2' (default: 'http1')
### Port80Handler (IAcmeOptions)
- `enabled` (boolean, default true)
- `port` (number, default 80)
- `contactEmail` (string)
- `useProduction` (boolean, default false)
- `renewThresholdDays` (number, default 30)
- `autoRenew` (boolean, default true)
- `certificateStore` (string)
- `skipConfiguredCerts` (boolean)
- `domainForwards` (IDomainForwardConfig[])
Controls the protocol used when proxying requests to backend services. By default, the proxy uses HTTP/1.x (`http.request`). Setting `backendProtocol: 'http2'` establishes HTTP/2 client sessions (`http2.connect`) to your backends for full end-to-end HTTP/2 support (assuming your backend servers support HTTP/2).
### NfTablesProxy (INfTableProxySettings)
- `fromPort` / `toPort` (number|range|array)
- `toHost` (string, default 'localhost')
- `preserveSourceIP`, `deleteOnExit`, `protocol`, `enableLogging`, `ipv6Support` (booleans)
- `allowedSourceIPs`, `bannedSourceIPs` (string[])
- `useIPSets` (boolean, default true)
- `qos`, `netProxyIntegration` (objects)
Example:
```js
import { NetworkProxy } from '@push.rocks/smartproxy';
### Redirect / SslRedirect
- Constructor options: `httpPort`, `httpsPort`, `sslOptions`, `rules` (RedirectRule[])
const proxy = new NetworkProxy({
port: 8443,
backendProtocol: 'http2',
// other options...
});
proxy.start();
```
- **Basic Authentication** - Support for basic auth on proxied routes
- **Connection Management** - Intelligent connection tracking and cleanup with configurable timeouts
- **Browser Compatibility** - Optimized for modern browsers with fixes for common TLS handshake issues
## Installation
```bash
npm install @push.rocks/smartproxy
```
## Usage
### Basic Reverse Proxy Setup

});
// Define reverse proxy configurations
const proxyConfigs = [
{
hostName: 'example.com',
destinationIps: ['127.0.0.1'],
destinationPorts: [3000],
publicKey: 'your-cert-content',
privateKey: 'your-key-content',
rewriteHostHeader: true
},
{
hostName: 'api.example.com',
destinationIps: ['127.0.0.1'],
destinationPorts: [4000],
publicKey: 'your-cert-content',
privateKey: 'your-key-content',
// Optional basic auth
authentication: {
type: 'Basic',
user: 'admin',
pass: 'secret'
}

useProduction: true, // Use Let's Encrypt production servers (default is staging)
renewThresholdDays: 30, // Renew certificates 30 days before expiry
httpsRedirectPort: 443 // Redirect HTTP to HTTPS on this port
});
// Add domains to manage certificates for
acmeHandler.addDomain({
domainName: 'example.com',
sslRedirect: true,
acmeMaintenance: true
});
acmeHandler.addDomain({
domainName: 'api.example.com',
sslRedirect: true,
acmeMaintenance: true
});
// Support for glob pattern domains for routing (certificates not issued for glob patterns)
acmeHandler.addDomain({
domainName: '*.example.com',
sslRedirect: true,
acmeMaintenance: false, // Can't issue certificates for wildcard domains via HTTP-01
forward: { ip: '192.168.1.10', port: 8080 } // Forward requests to this target
});

## Advanced Features
### TLS Handshake Optimization
The enhanced `SmartProxy` implementation includes significant improvements for TLS handshake handling:
- Robust SNI extraction with improved error handling
- Increased buffer size for complex TLS handshakes (10MB)
- Longer initial handshake timeout (60 seconds)
- Detection and tracking of TLS connection states
- Optional detailed TLS debug logging for troubleshooting
- Browser compatibility fixes for Chrome certificate errors
```typescript
// Example configuration to solve Chrome certificate errors
const portProxy = new SmartProxy({
// ... other settings
initialDataTimeout: 60000, // Give browser more time for handshake
maxPendingDataSize: 10 * 1024 * 1024, // Larger buffer for complex handshakes
enableTlsDebugLogging: true, // Enable when troubleshooting
});
```
### Connection Management and Monitoring
The `SmartProxy` class includes built-in connection tracking and monitoring:
- Automatic cleanup of idle connections with configurable timeouts
- Timeouts for connections that exceed maximum lifetime
- Detailed logging of connection states
- Termination statistics
- Randomized timeouts to prevent "thundering herd" problems
- Per-domain timeout configuration
### WebSocket Support
The `NetworkProxy` class provides WebSocket support with:
- WebSocket connection proxying
- Automatic heartbeat monitoring
- Connection cleanup for inactive WebSockets
### SNI-based Routing
The `SmartProxy` class can inspect the SNI (Server Name Indication) field in TLS handshakes to route connections based on the requested domain:
- Multiple backend targets per domain
- Round-robin load balancing
- Domain-specific allowed IP ranges
- Protection against SNI renegotiation attacks
### Enhanced NfTables Management
The `NfTablesProxy` class offers advanced capabilities:
- Support for multiple port ranges and individual ports
- More efficient IP filtering using nftables sets
- IPv6 support with full feature parity
- Quality of Service (QoS) features including bandwidth limiting and traffic prioritization
- Advanced connection tracking for stateful NAT
- Robust error handling with retry mechanisms
- Structured logging with JSON support
- NetworkProxy integration for SSL termination
- Comprehensive cleanup on shutdown
### Port80Handler with Glob Pattern Support
The `Port80Handler` class includes support for glob pattern domain matching:
- Supports wildcard domains like `*.example.com` for HTTP request routing
- Detects glob patterns and skips certificate issuance for them
- Smart routing that first attempts exact matches, then tries pattern matching
- Supports forwarding HTTP requests to backend services
- Separate forwarding configuration for ACME challenges
### SmartProxy (IPortProxySettings)
- `fromPort`, `toPort` (number)
- `domainConfigs` (IDomainConfig[])
- `sniEnabled`, `defaultAllowedIPs`, `preserveSourceIP` (booleans)
- Timeouts: `initialDataTimeout`, `socketTimeout`, `inactivityTimeout`, etc.
- Socket opts: `noDelay`, `keepAlive`, `enableKeepAliveProbes`
- `acme` (IAcmeOptions), `certProvisionFunction` (callback)
- `useNetworkProxy` (number[]), `networkProxyPort` (number)
## Troubleshooting
### Browser Certificate Errors
### NetworkProxy
- Verify ports, certificates and `rejectUnauthorized` for TLS errors
- Configure CORS or use `addDefaultHeaders` for preflight issues
- Increase `maxConnections` or `connectionPoolSize` under load
If you experience certificate errors in browsers, especially in Chrome, try these solutions:
### Port80Handler
- Run as root or grant CAP_NET_BIND_SERVICE for port 80
- Inspect `certificate-failed` events and switch staging/production
1. **Increase Initial Data Timeout**: Set `initialDataTimeout` to 60 seconds or higher
2. **Increase Buffer Size**: Set `maxPendingDataSize` to 10MB or higher
3. **Enable TLS Debug Logging**: Set `enableTlsDebugLogging: true` to troubleshoot handshake issues
4. **Enable Keep-Alive Probes**: Set `enableKeepAliveProbes: true` for better connection stability
5. **Check Certificate Chain**: Ensure your certificate chain is complete and in the correct order
### NfTablesProxy
- Ensure `nft` is installed and run with sufficient privileges
- Use `forceCleanSlate:true` to clear conflicting rules
```typescript
// Configuration to fix Chrome certificate errors
const smartProxy = new SmartProxy({
// ... other settings
initialDataTimeout: 60000,
maxPendingDataSize: 10 * 1024 * 1024,
enableTlsDebugLogging: true,
enableKeepAliveProbes: true
});
```
### Redirect / SslRedirect
- Check `fromHost`/`fromPath` patterns and Host headers
- Validate `sslOptions` key/cert correctness
### Connection Stability
For improved connection stability in high-traffic environments:
1. **Set Appropriate Timeouts**: Use longer timeouts for long-lived connections
2. **Use Domain-Specific Timeouts**: Configure per-domain timeouts for different types of services
3. **Enable TCP Keep-Alive**: Ensure `keepAlive` is set to `true`
4. **Monitor Connection Statistics**: Enable detailed logging to track termination reasons
5. **Fine-tune Inactivity Checks**: Adjust `inactivityCheckInterval` based on your traffic patterns
### NfTables Troubleshooting
If you're experiencing issues with NfTablesProxy:
1. **Enable Detailed Logging**: Set `enableLogging: true` to see all rule operations
2. **Force Clean Slate**: Use `forceCleanSlate: true` to remove any lingering rules
3. **Use IP Sets**: Enable `useIPSets: true` for cleaner rule management
4. **Check Permissions**: Ensure your process has sufficient permissions to modify nftables
5. **Verify IPv6 Support**: If using `ipv6Support: true`, ensure ip6tables is available
### SmartProxy & SniHandler
- Increase `initialDataTimeout`/`maxPendingDataSize` for large ClientHello
- Enable `enableTlsDebugLogging` to trace handshake
- Ensure `allowSessionTicket` and fragmentation support for resumption

# Project Simplification Plan
# SmartProxy Unified Forwarding Configuration Plan
This document outlines a roadmap to simplify and refactor the SmartProxy & NetworkProxy codebase for better maintainability, reduced duplication, and clearer configuration.
## Project Goal
Create a clean, use-case driven forwarding configuration interface for SmartProxy that elegantly handles all forwarding scenarios: SNI-based forwarding, termination-based forwarding (NetworkProxy), HTTP forwarding, and ACME challenge forwarding.
## 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 State
Currently, SmartProxy has several different forwarding mechanisms configured separately:
1. **HTTPS/SNI forwarding** via `IDomainConfig` properties
2. **NetworkProxy forwarding** via `useNetworkProxy` in domain configs
3. **HTTP forwarding** via Port80Handler's `forward` configuration
4. **ACME challenge forwarding** via `acmeForward` configuration
## 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
- [ ] Unify configuration options:
- [x] Merge `INetworkProxyOptions.acme`, `IPort80HandlerOptions`, and `port80HandlerConfig` into one schema
- [ ] Deprecate old option names and provide clear upgrade path
- [ ] Centralize plugin imports in `ts/plugins.ts` and update all modules to use it
- [ ] 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
This separation creates configuration complexity and reduced cohesion between related settings.
Once these steps are complete, the project will be cleaner, easier to understand, and simpler to extend.
## Proposed Solution: Clean Use-Case Driven Forwarding Interface
### Phase 1: Design Streamlined Forwarding Interface
- [ ] Create a use-case driven `IForwardConfig` interface that simplifies configuration:
```typescript
export interface IForwardConfig {
// Define the primary forwarding type - use-case driven approach
type: 'http-only' | 'https-passthrough' | 'https-terminate-to-http' | 'https-terminate-to-https';
// Target configuration
target: {
host: string | string[]; // Support single host or round-robin
port: number;
};
// HTTP-specific options
http?: {
enabled?: boolean; // Defaults to true for http-only, optional for others
redirectToHttps?: boolean; // Redirect HTTP to HTTPS
headers?: Record<string, string>; // Custom headers for HTTP responses
};
// HTTPS-specific options
https?: {
customCert?: { // Use custom cert instead of auto-provisioned
key: string;
cert: string;
};
forwardSni?: boolean; // Forward SNI info in passthrough mode
};
// ACME certificate handling
acme?: {
enabled?: boolean; // Enable ACME certificate provisioning
maintenance?: boolean; // Auto-renew certificates
production?: boolean; // Use production ACME servers
forwardChallenges?: { // Forward ACME challenges
host: string;
port: number;
useTls?: boolean;
};
};
// Security options
security?: {
allowedIps?: string[]; // IPs allowed to connect
blockedIps?: string[]; // IPs blocked from connecting
maxConnections?: number; // Max simultaneous connections
};
// Advanced options
advanced?: {
portRanges?: Array<{ from: number; to: number }>; // Allowed port ranges
networkProxyPort?: number; // Custom NetworkProxy port if using terminate mode
keepAlive?: boolean; // Enable TCP keepalive
timeout?: number; // Connection timeout in ms
headers?: Record<string, string>; // Custom headers with support for variables like {sni}
};
}
```
### Phase 2: Create New Domain Configuration Interface
- [ ] Replace existing `IDomainConfig` interface with a new one using the forwarding pattern:
```typescript
export interface IDomainConfig {
// Core properties
domains: string[]; // Domain patterns to match
// Unified forwarding configuration
forwarding: IForwardConfig;
}
```
### Phase 3: Implement Forwarding Handler System
- [ ] Create an implementation strategy focused on the new forwarding types:
```typescript
/**
* Base class for all forwarding handlers
*/
abstract class ForwardingHandler {
constructor(protected config: IForwardConfig) {}
abstract handleConnection(socket: Socket): void;
abstract handleHttpRequest(req: IncomingMessage, res: ServerResponse): void;
}
/**
* Factory for creating the appropriate handler based on forwarding type
*/
class ForwardingHandlerFactory {
public static createHandler(config: IForwardConfig): ForwardingHandler {
switch (config.type) {
case 'http-only':
return new HttpForwardingHandler(config);
case 'https-passthrough':
return new HttpsPassthroughHandler(config);
case 'https-terminate-to-http':
return new HttpsTerminateToHttpHandler(config);
case 'https-terminate-to-https':
return new HttpsTerminateToHttpsHandler(config);
default:
throw new Error(`Unknown forwarding type: ${config.type}`);
}
}
}
```
## Usage Examples for Common Scenarios
### 1. Basic HTTP Server
```typescript
{
domains: ['example.com'],
forwarding: {
type: 'http-only',
target: {
host: 'localhost',
port: 3000
}
}
}
```
### 2. HTTPS Termination with HTTP Backend
```typescript
{
domains: ['secure.example.com'],
forwarding: {
type: 'https-terminate-to-http',
target: {
host: 'localhost',
port: 3000
},
acme: {
production: true // Use production Let's Encrypt
}
}
}
```
### 3. HTTPS Termination with HTTPS Backend
```typescript
{
domains: ['secure-backend.example.com'],
forwarding: {
type: 'https-terminate-to-https',
target: {
host: 'internal-api',
port: 8443
},
http: {
redirectToHttps: true // Redirect HTTP requests to HTTPS
}
}
}
```
### 4. SNI Passthrough
```typescript
{
domains: ['passthrough.example.com'],
forwarding: {
type: 'https-passthrough',
target: {
host: '10.0.0.5',
port: 443
}
}
}
```
### 5. Mixed HTTP/HTTPS with Custom ACME Forwarding
```typescript
{
domains: ['mixed.example.com'],
forwarding: {
type: 'https-terminate-to-http',
target: {
host: 'localhost',
port: 3000
},
http: {
redirectToHttps: false // Allow both HTTP and HTTPS access
},
acme: {
enabled: true,
maintenance: true,
forwardChallenges: {
host: '192.168.1.100',
port: 8080
}
}
}
}
```
### 6. Load-Balanced Backend
```typescript
{
domains: ['api.example.com'],
forwarding: {
type: 'https-terminate-to-https',
target: {
host: ['10.0.0.10', '10.0.0.11', '10.0.0.12'], // Round-robin
port: 8443
},
security: {
allowedIps: ['10.0.0.*', '192.168.1.*'] // Restrict access
}
}
}
```
### 7. Advanced Proxy Chain with Custom Headers
```typescript
{
domains: ['secure-chain.example.com'],
forwarding: {
type: 'https-terminate-to-https',
target: {
host: 'backend-gateway.internal',
port: 443
},
advanced: {
// Pass original client info to backend
headers: {
'X-Original-SNI': '{sni}',
'X-Client-IP': '{clientIp}'
}
}
}
}
```

## Detailed Type Documentation
### Core Forwarding Types
```typescript
/**
* The primary forwarding types supported by SmartProxy
*/
export type ForwardingType =
| 'http-only' // HTTP forwarding only (no HTTPS)
| 'https-passthrough' // Pass-through TLS traffic (SNI forwarding)
| 'https-terminate-to-http' // Terminate TLS and forward to HTTP backend
| 'https-terminate-to-https'; // Terminate TLS and forward to HTTPS backend
```
### Type-Specific Behavior
Each forwarding type has specific default behavior:
#### HTTP-Only
- Handles only HTTP traffic
- No TLS/HTTPS support
- No certificate management
#### HTTPS Passthrough
- Forwards raw TLS traffic to backend (no termination)
- Passes SNI information through
- No HTTP support (TLS only)
- No certificate management
#### HTTPS Terminate to HTTP
- Terminates TLS at SmartProxy
- Connects to backend using HTTP (non-TLS)
- Manages certificates automatically (ACME)
- Supports HTTP requests with option to redirect to HTTPS
#### HTTPS Terminate to HTTPS
- Terminates client TLS at SmartProxy
- Creates new TLS connection to backend
- Manages certificates automatically (ACME)
- Supports HTTP requests with option to redirect to HTTPS
## Handler Implementation Strategy
```typescript
/**
* Handler for HTTP-only forwarding
*/
class HttpForwardingHandler extends ForwardingHandler {
public handleConnection(socket: Socket): void {
// Process HTTP connection
// For HTTP-only, we'll mostly defer to handleHttpRequest
}
public handleHttpRequest(req: IncomingMessage, res: ServerResponse): void {
// Forward HTTP request to target
const target = this.getTargetFromConfig();
this.proxyRequest(req, res, target);
}
}
/**
* Handler for HTTPS passthrough (SNI forwarding)
*/
class HttpsPassthroughHandler extends ForwardingHandler {
public handleConnection(socket: Socket): void {
// Extract SNI from TLS ClientHello if needed
// Forward raw TLS traffic to target without termination
const target = this.getTargetFromConfig();
this.forwardTlsConnection(socket, target);
}
public handleHttpRequest(req: IncomingMessage, res: ServerResponse): void {
// HTTP not supported in SNI passthrough mode
res.statusCode = 404;
res.end('HTTP not supported for this domain');
}
}
/**
* Handler for HTTPS termination with HTTP backend
*/
class HttpsTerminateToHttpHandler extends ForwardingHandler {
private tlsContext: SecureContext;
public async initialize(): Promise<void> {
// Set up TLS termination context
this.tlsContext = await this.createTlsContext();
}
public handleConnection(socket: Socket): void {
// Terminate TLS
const tlsSocket = this.createTlsSocket(socket, this.tlsContext);
// Forward to HTTP backend after TLS termination
tlsSocket.on('data', (data) => {
this.forwardToHttpBackend(data);
});
}
public handleHttpRequest(req: IncomingMessage, res: ServerResponse): void {
if (this.config.http?.redirectToHttps) {
// Redirect to HTTPS if configured
this.redirectToHttps(req, res);
} else {
// Handle HTTP request
const target = this.getTargetFromConfig();
this.proxyRequest(req, res, target);
}
}
}
/**
* Handler for HTTPS termination with HTTPS backend
*/
class HttpsTerminateToHttpsHandler extends ForwardingHandler {
private tlsContext: SecureContext;
public async initialize(): Promise<void> {
// Set up TLS termination context
this.tlsContext = await this.createTlsContext();
}
public handleConnection(socket: Socket): void {
// Terminate client TLS
const tlsSocket = this.createTlsSocket(socket, this.tlsContext);
// Create new TLS connection to backend
tlsSocket.on('data', (data) => {
this.forwardToHttpsBackend(data);
});
}
public handleHttpRequest(req: IncomingMessage, res: ServerResponse): void {
if (this.config.http?.redirectToHttps) {
// Redirect to HTTPS if configured
this.redirectToHttps(req, res);
} else {
// Handle HTTP request via HTTPS to backend
const target = this.getTargetFromConfig();
this.proxyRequestOverHttps(req, res, target);
}
}
}
```
## Benefits of This Approach
1. **Clean, Type-Driven Design**
- Forwarding types clearly express intent
- No backward compatibility compromises
- Code structure follows the domain model
2. **Explicit Configuration**
- Configuration directly maps to behavior
- Reduced chance of unexpected behavior
3. **Modular Implementation**
- Each forwarding type handled by dedicated class
- Clear separation of concerns
- Easier to test and extend
4. **Simplified Mental Model**
- Users think in terms of use cases, not low-level settings
- Configuration matches mental model
5. **Future-Proof**
- Easy to add new forwarding types
- Clean extension points for new features
