# Changelog

|
||||
## 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)

## 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: {
|
||||

|
||||

|
||||

|
||||
},
|
||||

|
||||

|
||||
redirectToHttps: true
|
||||
},
|
||||
https: {
|
||||

|
||||
}
|
||||

# 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
|
||||
- [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
|
||||
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
