Repository Generator

Generate DDD-compliant Repository interfaces and implementation stubs.

Repository Characteristics

Interface in Domain: Contract defined in Domain layer
Implementation in Infrastructure: Doctrine/Eloquent/etc. implementation
Works with Aggregates: Not entities directly
Collection-like: Find, save, remove operations
No business logic: Only persistence operations

Generation Process

Step 1: Generate Interface

Path:

src/Domain/{BoundedContext}/Repository/

```
{AggregateRoot}RepositoryInterface.php
```
— Domain contract

Step 2: Generate Implementation

Path:

src/Infrastructure/Persistence/Doctrine/

```
Doctrine{AggregateRoot}Repository.php
```
— Doctrine implementation

Step 3: Generate In-Memory Repository (Optional)

Path:

tests/Infrastructure/Persistence/

```
InMemory{AggregateRoot}Repository.php
```
— For unit testing

Step 4: Generate Integration Tests

Path:

tests/Integration/Infrastructure/Persistence/

File Placement

Component	Path
Interface	`src/Domain/{BoundedContext}/Repository/`
Doctrine Impl	`src/Infrastructure/Persistence/Doctrine/`
In-Memory	`tests/Infrastructure/Persistence/`
Integration Tests	`tests/Integration/Infrastructure/Persistence/`

Naming Conventions

Component	Pattern	Example
Interface	`{AggregateRoot}RepositoryInterface`	`OrderRepositoryInterface`
Doctrine Impl	`Doctrine{AggregateRoot}Repository`	`DoctrineOrderRepository`
In-Memory	`InMemory{AggregateRoot}Repository`	`InMemoryOrderRepository`

Quick Template Reference

Interface

interface {AggregateRoot}RepositoryInterface
{
    public function findById({AggregateRoot}Id $id): ?{AggregateRoot};

    public function save({AggregateRoot} $aggregate): void;

    public function remove({AggregateRoot} $aggregate): void;

    public function nextIdentity(): {AggregateRoot}Id;
}

Doctrine Implementation

final readonly class Doctrine{AggregateRoot}Repository implements {AggregateRoot}RepositoryInterface
{
    public function __construct(
        private EntityManagerInterface $em
    ) {}

    public function findById({AggregateRoot}Id $id): ?{AggregateRoot}
    {
        return $this->em->find({AggregateRoot}::class, $id->value);
    }

    public function save({AggregateRoot} $aggregate): void
    {
        $this->em->persist($aggregate);
        $this->em->flush();
    }

    public function remove({AggregateRoot} $aggregate): void
    {
        $this->em->remove($aggregate);
        $this->em->flush();
    }

    public function nextIdentity(): {AggregateRoot}Id
    {
        return {AggregateRoot}Id::generate();
    }
}

In-Memory Implementation

final class InMemory{AggregateRoot}Repository implements {AggregateRoot}RepositoryInterface
{
    private array $items = [];

    public function findById({AggregateRoot}Id $id): ?{AggregateRoot}
    {
        return $this->items[$id->value] ?? null;
    }

    public function save({AggregateRoot} $aggregate): void
    {
        $this->items[$aggregate->id()->value] = $aggregate;
    }

    public function clear(): void
    {
        $this->items = [];
    }
}

Design Rules

Rule	Good	Bad
Layer Placement	Interface in Domain	Interface in Infrastructure
Aggregate Scope	Repository per aggregate root	Repository per entity
Query Methods	Simple filters	Business logic in queries
Identity	`nextIdentity()` method	External ID generation

Anti-patterns to Avoid

Anti-pattern	Problem	Solution
Entity Repository	Bypasses aggregate	Only aggregate roots
Business Queries	Logic in repository	Use Specification pattern
Infrastructure Leak	Domain depends on ORM	Interface in Domain
Generic Repository	Too abstract	Specific per aggregate
Missing nextIdentity	Can't generate IDs	Add to interface
