skill helps you implement DDD code that follows established patterns and rules: + +✅ **Aggregates** - With proper invariant enforcement and Result types +✅ **Entities** - Child entities within aggregates +✅ **Value Objects** - Immutable, self-validating +✅ **Use Cases** - In application layer with proper error handling +✅ **Repositories** - Interfaces in domain, implementations in infrastructure +✅ **Domain Events** - For cross-aggregate communication + +## When to Use This Skill + +**Use `/ddd-implement` when**: +- You have a domain model designed (from `/ddd-model`) +- You need to implement specific aggregates, entities, or value objects +- You want code that follows DDD rules automatically +- You need proper error handling (Result types for Java, errors for Go) +- You

Usage Examples + +### Implement an Aggregate + +```bash +/ddd-implement --lang=java "Implement Order aggregate with addLineItem, removeLineItem, and cancel methods" +``` + +The skill will: +1.

Add domain events (OrderCreated, OrderCancelled, etc.) + +### Implement a Use Case + +```bash +/ddd-implement --lang=go "Implement PlaceOrder use case that creates an order and reserves inventory" +``` + +The skill will: +1.

Add transaction boundaries if needed + +### Implement a Repository + +```bash +/ddd-implement --lang=java "Implement PostgreSQL repository for Order aggregate" +``` + +The skill will: +1. Create implementation in `infrastructure/order/persistence/` +2. Implement the domain interface +3. Add exception boundary (catch SQL exceptions → return domain errors) +4. Map between domain model and database schema + +### Implement from Existing File + +```bash +/ddd-implement internal/domain/account/account.go +``` + +The skill will: +1.

Aggregate Rules +- ✅ Aggregate Root is the ONLY public entry point +- ✅ Child entities accessed ONLY via aggregate methods +- ✅ NO direct references to other aggregates (use IDs only) +- ✅ One aggregate = one transaction boundary +- ✅ All invariants documented with `// Invariant:` or `@Invariant` comments +- ✅ Invariants checked in constructor AND mutation methods + +**Example**: +```java +/** + * Account aggregate root. + * + * Invariant: Balance >= 0 for standard accounts + * Invariant: Must have at least one OWNER holder + */ +public class Account { + // Invariant enforced in constructor + public static Result create(...) { + // Check invariants + } + + // Invariant enforced in withdraw + public Result withdraw(Money amount) { + // Check invariants + } +} +``` + +### 2. Entity Rules +- ✅ **Package-private constructor** (created by aggregate) +- ✅ **Equality based on ID only** +- ✅ **No public factory methods** (aggregate creates entities) +- ✅ **Local invariants only** (aggregate handles aggregate-wide invariants) + +**Example** (Java): +```java +public class Holder { + private final HolderID id; + private HolderRole role; + + // Package-private - created by Account aggregate + Holder(HolderID id, HolderRole role) { + this.id = id; + this.role = role; + } + + // Package-private mutation + Result changeRole(HolderRole newRole) { + // ... + } + + @Override + public boolean equals(Object o) { + // Equality based on ID only! + return Objects.equals(id, ((Holder) o).id); + } +} +``` + +### 3. Value Object Rules +- ✅ **Immutable** (no setters, final fields) +- ✅ **Validation in constructor** or factory method +- ✅ **Equality compares ALL fields** +- ✅ **Operations return NEW instances** +- ✅ **Self-validating** (invalid state impossible) + +**Example** (Java with Result): +```java +public class Money { + private final long amountInCents; + private final String currency; + + private Money(long amountInCents, String currency) { + this.amountInCents = amountInCents; + this.currency = currency; + } + + public static Result create(long amount, String currency) { + if (currency == null || currency.length() != 3) { + return Result.failure(new InvalidCurrencyError(currency)); + } + return Result.success(new Money(amount, currency)); + } + + // Operations return NEW instances + public Result add(Money other) { + if (!this.currency.equals(other.currency)) { + return Result.failure(new CurrencyMismatchError(...)); + } + return Result.success(new Money( + this.amountInCents + other.amountInCents, + this.currency + )); + } + + @Override + public boolean equals(Object o) { + // Compare ALL fields + return amountInCents == other.amountInCents + && currency.equals(other.currency); + } +} +``` + +### 4. Repository Rules +- ✅ **Interface in domain layer** +- ✅ **Implementation in infrastructure layer** +- ✅ **Operate on aggregates only** (not entities) +- ✅ **Return Result types** (Java) or **error** (Go) +- ✅ **Domain-specific errors** (AccountNotFoundError, not generic exceptions) + +**Example** (Java): +```java +// Domain layer: internal/domain/account/repository.java +public interface AccountRepository { + Result save(Account account); + Result findById(AccountID id); +} + +// Infrastructure layer: internal/infrastructure/account/persistence/jdbc_repository.java +public class JdbcAccountRepository implements AccountRepository { + @Override + public Result save(Account account) { + try { + // JDBC implementation + return Result.success(null); + } catch (SQLException e) { + log.error("Failed to save account", e); // Log at ERROR + return Result.failure(new DatabaseError(e.getMessage())); // Return domain error + } + } +} +``` + +### 5.

Bean validation (`@Valid`, `@NotBlank`, etc.) +- **SpringDoc OpenAPI**: Swagger/OpenAPI documentation +- **SLF4J**: Logging + +## Best Practices + +1. **Controller Responsibilities** + - Handle HTTP concerns (requests, responses, status codes) + - Convert between DTOs and commands + - Delegate business logic to use cases + - Extract ActorId from SecurityContext + - Check authorization for sensitive operations + +2. **DTO Design** + - Immutable records + - Bean validation annotations + - OpenAPI/Swagger annotations + - Separate request/response DTOs + +3. **Error Handling** + - Centralized via `GlobalExceptionHandler` + - Consistent error response format + - Appropriate HTTP status codes + - Don't expose internal details in production + +4. **Security** + - Always extract ActorId for audit logging + - Check authorization for ADMIN operations + - Validate all user input + - Use HTTPS in production + +5. **API Design** + - RESTful URLs + - Proper HTTP methods (GET, POST, PUT, DELETE) + - Idempotent operations where appropriate + - Versioned API (future: `/api/v1/users`) + +## Testing + +### Manual Testing with curl + +**Login:** +```bash +curl -X POST http://localhost:8080/api/auth/login \ + -H "Content-Type: application/json" \ + -d '{"username":"admin","password":"admin123"}' +``` + +**List Users (with JWT):** +```bash +curl -X GET http://localhost:8080/api/users \ + -H "Authorization: Bearer " +``` + +**Create User (ADMIN):** +```bash +curl -X POST http://localhost:8080/api/users \ + -H "Authorization: Bearer " \ + -H "Content-Type: application/json" \ + -d '{ + "username": "john.doe", + "email": "john.doe@example.com", + "password": "SecurePass123", + "roleNames": ["USER"], + "branchId": "BRANCH-001" + }' +``` + +### Integration Testing +- See `src/test/java/de/effigenix/infrastructure/web/usermanagement/` for integration tests +- Uses `@SpringBootTest` and `MockMvc` +- Tests authentication, authorization, error handling + +## Future Enhancements + +1. **API Versioning**: `/api/v1/users` +2. **Rate Limiting**: Prevent API abuse +3. **CORS Configuration**: Configure allowed origins +4. **Request Logging**: Log all API requests +5. **Response Caching**: Cache GET requests +6. **Pagination**: For list endpoints +7. **Filtering/Sorting**: Query parameters for list endpoints +8. **HATEOAS**: Add hypermedia links to responses +9. **GraphQL**: Alternative to REST for complex queries +10. **WebSocket**: For real-time updates + +## Production Considerations + +1. **Security** + - Enable HTTPS (TLS/SSL) + - Restrict Swagger UI access + - Configure CORS properly + - Enable CSRF protection (if using cookies) + - Use secure JWT signing key (store in environment variables) + +2. **Performance** + - Enable response compression (GZIP) + - Add caching headers + - Use connection pooling + - Monitor response times + +3. **Monitoring** + - Add Spring Actuator endpoints + - Configure metrics (Prometheus/Grafana) + - Add distributed tracing (Zipkin/Jaeger) + - Log all errors with correlation IDs + +4. **Error Handling** + - Don't expose stack traces in responses + - Generic error messages for security + - Log detailed errors server-side + - Add error tracking (Sentry/Rollbar) + +## References + +- [Spring Web Documentation](https://spring.io/guides/gs/rest-service/) +- [Spring Security
