Doctrine ORM bridge for DDD Foundation. This package provides repository and paginator implementations using Doctrine, plus custom DBAL types for Value Objects.

Pure PHP - No framework dependency. Use with any PHP framework.

Installation

composer require alexandrebulete/ddd-doctrine-bridge

For Symfony integration, also install:

Repository Traits

Granular traits to compose your repositories with only the capabilities you need.

Capability Traits (High-level)

Operation Traits (Atomic)

Usage Examples

Full CRUD Repository

use AlexandreBulete\DddDoctrineBridge\DoctrineRepository;
use AlexandreBulete\DddDoctrineBridge\Capability\AsCrudable;
use AlexandreBulete\DddFoundation\Application\Event\EventDispatcherInterface;

class DoctrinePostRepository extends DoctrineRepository implements PostRepositoryInterface
{
    use AsCrudable;

    public function __construct(
        EntityManagerInterface $em,
        private readonly EventDispatcherInterface $eventDispatcher,
    ) {
        parent::__construct($em, Post::class, 'post');
    }

    public function save(Post $post): void
    {
        $this->persistAndFlush(
            entity: $post,
            dispatchEvents: true,
            whenDispatchEvents: WhenDispatchDomainEventsEnum::AFTER,
        );
    }

    public function delete(Post $post): void
    {
        $this->removeAndFlush($post);
    }

    public function findById(IdentifierVO $id): ?Post
    {
        return $this->findEntityById(Post::class, $id->toRfc4122());
    }

    public function findAll(): array
    {
        return $this->findAllEntities();
    }
}

Read-Only Repository

use AlexandreBulete\DddDoctrineBridge\DoctrineRepository;
use AlexandreBulete\DddDoctrineBridge\Capability\AsReadable;

class DoctrineCountryRepository extends DoctrineRepository
{
    use AsReadable;

    public function __construct(EntityManagerInterface $em)
    {
        parent::__construct($em, Country::class, 'country');
    }

    public function findById(IdentifierVO $id): ?Country
    {
        return $this->findEntityById(Country::class, $id->value());
    }

    public function findAll(): array
    {
        return $this->findAllEntities();
    }
}

Custom Mix (Persist without Delete)

use AlexandreBulete\DddDoctrineBridge\DoctrineRepository;
use AlexandreBulete\DddDoctrineBridge\Capability\AsReadable;
use AlexandreBulete\DddDoctrineBridge\Operation\CanPersist;
use AlexandreBulete\DddDoctrineBridge\DispatchesDomainEvents;

class DoctrineAuditLogRepository extends DoctrineRepository
{
    use AsReadable;
    use CanPersist;
    use DispatchesDomainEvents;

    // Can read and create, but NOT delete
}

Domain Events

Dispatch domain events from your aggregates after persistence.

When to Dispatch

use AlexandreBulete\DddDoctrineBridge\Enum\WhenDispatchDomainEventsEnum;

// Dispatch AFTER flush (recommended - ensures transaction committed)
$this->persistAndFlush($entity, dispatchEvents: true, whenDispatchEvents: WhenDispatchDomainEventsEnum::AFTER);

// Dispatch BEFORE flush (rare - event dispatched even if flush fails)
$this->persistAndFlush($entity, dispatchEvents: true, whenDispatchEvents: WhenDispatchDomainEventsEnum::BEFORE);

Requirements

Your entity must use the RecordsEvents trait from ddd-foundation:

use AlexandreBulete\DddFoundation\Domain\Model\RecordsEvents;

class Post
{
    use RecordsEvents;

    public function publish(): void
    {
        $this->status = 'published';
        $this->recordEvent(new PostPublished($this->id));
    }
}

Custom Doctrine Types

Create custom Doctrine types for your Value Objects:

use AlexandreBulete\DddDoctrineBridge\Type\GuidType;
use App\Post\Domain\ValueObject\PostId;

class PostIdType extends GuidType
{
    protected string $name = 'post_id';
    protected string $voClass = PostId::class;
}

Available Base Types

• GuidType: For UUID/ULID identifier value objects
• VarcharType: For string value objects (VARCHAR)
• TextType: For string value objects (TEXT/CLOB)
