Anti-Corruption Layer Generator

Generate DDD-compliant Anti-Corruption Layer (ACL) components for isolating bounded contexts and integrating with external/legacy systems.

When to Use

Scenario	Example
Legacy system integration	ERP, CRM, mainframe
Third-party API integration	Payment gateway, shipping API
Bounded context communication	Order ↔ Inventory contexts
Database migration	Old schema → new domain model
Microservice integration	External service with different model

Anti-Corruption Layer Characteristics

Isolation: Protects domain model from external/foreign concepts
Translation: Converts between domain and external models
Facade: Provides simplified interface to external systems
Adapter: Implements domain ports using external services
No Domain Leakage: External concepts never enter domain layer
Bidirectional: Can translate both inbound and outbound

Generation Process

Step 1: Generate Domain Port

Path:

src/Domain/{BoundedContext}/Port/

```
{ExternalSystem}PortInterface.php
```
— Domain interface for external system

Step 2: Generate External DTOs

Path:

src/Infrastructure/{BoundedContext}/ACL/{ExternalSystem}/DTO/

```
{ExternalSystem}{Concept}DTO.php
```
— DTOs matching external format

Step 3: Generate Translator

Path:

src/Infrastructure/{BoundedContext}/ACL/{ExternalSystem}/

```
{ExternalSystem}Translator.php
```
— Domain ↔ External conversion

Step 4: Generate Facade

Path:

src/Infrastructure/{BoundedContext}/ACL/{ExternalSystem}/

```
{ExternalSystem}Facade.php
```
— Simplified external system interface

Step 5: Generate Adapter

Path:

src/Infrastructure/{BoundedContext}/ACL/{ExternalSystem}/

```
{ExternalSystem}Adapter.php
```
— Implements domain port

Step 6: Generate Exceptions

Path:

src/Infrastructure/{BoundedContext}/ACL/{ExternalSystem}/Exception/

```
{ExternalSystem}Exception.php
```
— Domain exception
```
{ExternalSystem}ConnectionException.php
```
— Infrastructure exception

Step 7: Generate Tests

```
{ExternalSystem}TranslatorTest.php
```
— Translation tests
```
{ExternalSystem}AdapterTest.php
```
— Adapter integration tests

Naming Conventions

Component	Pattern	Example
Port	`{ExternalSystem}PortInterface`	`PaymentGatewayPortInterface`
DTO	`{ExternalSystem}{Concept}DTO`	`StripeChargeDTO`
Translator	`{ExternalSystem}Translator`	`StripeTranslator`
Facade	`{ExternalSystem}Facade`	`StripeFacade`
Adapter	`{ExternalSystem}Adapter`	`StripeAdapter`
Exception	`{ExternalSystem}Exception`	`StripeException`

Quick Template Reference

Domain Port

interface {ExternalSystem}PortInterface
{
    public function {operation}({DomainParameters}): {DomainReturnType};
}

Translator

final readonly class {ExternalSystem}Translator
{
    public function toDomain({ExternalSystem}DTO $dto): {Entity};
    public function toExternal({Entity} $entity): {ExternalSystem}DTO;
}

Adapter

final readonly class {ExternalSystem}Adapter implements {ExternalSystem}PortInterface
{
    public function __construct(
        private {ExternalSystem}Facade $facade,
        private {ExternalSystem}Translator $translator,
    ) {}

    public function {operation}({DomainParameters}): {DomainReturnType}
    {
        $dto = $this->translator->toExternal($entity);
        $result = $this->facade->{externalOperation}($dto);
        return $this->translator->toDomain($result);
    }
}

Usage Example

// Domain port interface
interface PaymentGatewayPortInterface
{
    public function charge(Payment $payment): PaymentId;
    public function refund(PaymentId $paymentId, Money $amount): void;
}

// Adapter implementation
final readonly class StripeAdapter implements PaymentGatewayPortInterface
{
    public function charge(Payment $payment): PaymentId
    {
        $stripeCharge = $this->translator->toStripeCharge($payment);
        $result = $this->facade->createCharge($stripeCharge);
        return $this->translator->toPaymentId($result);
    }
}

Anti-patterns to Avoid

Anti-pattern	Problem	Solution
Domain using external DTOs	External concepts leak into domain	Always translate at ACL boundary
Translator in domain layer	Infrastructure concern in domain	Keep translator in infrastructure
Exposing external exceptions	Coupling to external system	Wrap in domain exceptions
Direct API calls from domain	No isolation	Use port/adapter pattern
Shared DTOs across ACLs	Coupling between integrations	Each ACL has own DTOs
Business logic in translator	Wrong responsibility	Translator only maps data

DI Configuration

# services.yaml
Domain\Payment\Port\PaymentGatewayPortInterface:
    alias: Infrastructure\Payment\ACL\Stripe\StripeAdapter

Infrastructure\Payment\ACL\Stripe\StripeFacade:
    arguments:
        $client: '@stripe.client'
