Ecotone Laravel Setup

This creates config/ecotone.php.

2. Eloquent Aggregate

Ecotone automatically registers EloquentRepository -- Eloquent models extending Model are auto-detected as aggregates.

use Ecotone\Modelling\Attribute\Aggregate;
use Ecotone\Modelling\Attribute\AggregateIdentifierMethod;
use Ecotone\Modelling\Attribute\CommandHandler;
use Ecotone\Modelling\WithEvents;
use Illuminate\Database\Eloquent\Model;

#[Aggregate]
class Order extends Model
{
    use WithEvents;

    public $fillable = ['id', 'user_id', 'total_price', 'is_cancelled'];

    #[CommandHandler]
    public static function place(PlaceOrder $command): self
    {
        $order = self::create([
            'user_id' => $command->userId,
            'total_price' => $command->totalPrice,
            'is_cancelled' => false,
        ]);
        $order->recordThat(new OrderWasPlaced($order->id));
        return $order;
    }

    #[CommandHandler]
    public function cancel(CancelOrder $command): void
    {
        $this->is_cancelled = true;
        $this->save();
    }

    #[AggregateIdentifierMethod('id')]
    public function getId(): int
    {
        return $this->id;
    }
}

Key differences from regular aggregates:

• Extends Illuminate\Database\Eloquent\Model
• Use #[AggregateIdentifierMethod('id')] instead of #[Identifier] on properties
• Call $this->save() in action handlers
• Factory methods use self::create([...])
• Use WithEvents trait for recording domain events

3. Database Connection (DBAL)

#[ServiceContext]
public function databaseConnection(): LaravelConnectionReference
{
    return LaravelConnectionReference::defaultConnection('mysql');
}

The connection name matches the key in config/database.php connections array.

4. Async Messaging with Laravel Queue

#[ServiceContext]
public function asyncChannel(): LaravelQueueMessageChannelBuilder
{
    return LaravelQueueMessageChannelBuilder::create('notifications');
}

5. Running Async Consumers

php artisan ecotone:run <channel_name>
php artisan ecotone:run orders --handledMessageLimit=100
php artisan ecotone:run orders --memoryLimit=256
php artisan ecotone:run orders --executionTimeLimit=60000
php artisan ecotone:list

6. Multi-Tenant Configuration

#[ServiceContext]
public function multiTenant(): MultiTenantConfiguration
{
    return MultiTenantConfiguration::create(
        tenantHeaderName: 'tenant',
        tenantToConnectionMapping: [
            'tenant_a' => LaravelConnectionReference::create('tenant_a_connection'),
            'tenant_b' => LaravelConnectionReference::create('tenant_b_connection'),
        ],
    );
}

Key Rules

• LaravelConnectionReference::defaultConnection() takes the key from config/database.php connections array
• LaravelQueueMessageChannelBuilder::create() channel name must match an Ecotone async routing, optionally takes a queue connection name as second parameter
• Eloquent aggregates use #[AggregateIdentifierMethod] instead of #[Identifier] on properties
• Always use #[ServiceContext] methods in a class registered as a service for configuration
