This package brings the power of the Symfony Serializer component to Laravel. While Laravel does not have a built-in serializer and typically relies on array or JSON transformations, this package provides more advanced serialization capabilities. These include object normalization, handling of circular references, property grouping, and format-specific encoders.

If you are building a REST API, working with queues, or have complex serialization needs, this package will be especially useful. It allows you to use objects as payloads instead of simple arrays and supports various formats such as JSON, XML, CSV, and YAML. This documentation will guide you through the installation process and provide examples of how to use the package to serialize and deserialize your objects.

🙏 If you find this repository useful, please consider giving it a ⭐️. Thank you!

Require the package as a dependency:

composer require wayofdev/laravel-symfony-serializer

You can publish the config file with:

$ php artisan vendor:publish \
  --provider="WayOfDev\Serializer\Bridge\Laravel\Providers\SerializerServiceProvider" \
  --tag="config"

The package configuration file allows you to customize various aspects of the serialization process.

Below is the default configuration provided by the package:

<?php

declare(strict_types=1);

use Symfony\Component\Serializer\Mapping\Loader\LoaderInterface;
use WayOfDev\Serializer\Contracts\EncoderRegistrationStrategy;
use WayOfDev\Serializer\Contracts\NormalizerRegistrationStrategy;
use WayOfDev\Serializer\DefaultEncoderRegistrationStrategy;
use WayOfDev\Serializer\DefaultNormalizerRegistrationStrategy;

/**
 * @return array{
 *     default: string,
 *     debug: bool,
 *     normalizerRegistrationStrategy: class-string<NormalizerRegistrationStrategy>,
 *     encoderRegistrationStrategy: class-string<EncoderRegistrationStrategy>,
 *     metadataLoader: class-string<LoaderInterface>|null,
 * }
 */
return [
    'default' => env('SERIALIZER_DEFAULT_FORMAT', 'symfony-json'),

    'debug' => env('SERIALIZER_DEBUG_MODE', env('APP_DEBUG', false)),

    'normalizerRegistrationStrategy' => DefaultNormalizerRegistrationStrategy::class,

    'encoderRegistrationStrategy' => DefaultEncoderRegistrationStrategy::class,

    'metadataLoader' => null,
];

• default: Specifies the default serializer format. This can be overridden by setting the SERIALIZER_DEFAULT_FORMAT environment variable. The default is symfony-json.
• debug: Enables debug mode for ProblemNormalizer. This can be set using the SERIALIZER_DEBUG_MODE environment variable. It defaults to the APP_DEBUG value.
• normalizerRegistrationStrategy: Specifies the strategy class for registering normalizers. The default strategy is WayOfDev\Serializer\DefaultNormalizerRegistrationStrategy.
• encoderRegistrationStrategy: Specifies the strategy class for registering encoders. The default strategy is WayOfDev\Serializer\DefaultEncoderRegistrationStrategy.
• metadataLoader: Allows registration of a custom metadata loader. By default, Symfony\Component\Serializer\Mapping\Loader\AttributeLoader is used.

Due to Laravel's caching limitations, where configs cannot instantiate objects, this package uses strategies to register normalizers and encoders.

You can create custom normalizer or encoder registration strategies by implementing the respective interfaces.

To create a custom normalizer registration strategy:

1. Implement the NormalizerRegistrationStrategy interface:

   <?php
   
   declare(strict_types=1);
   
   namespace Infrastructure\Serializer;
   
   use Symfony\Component\Serializer\Mapping\Loader\LoaderInterface;
   use Symfony\Component\Serializer\Normalizer;
   use Symfony\Component\Serializer\Normalizer\DenormalizerInterface;
   use Symfony\Component\Serializer\Normalizer\NormalizerInterface;
   use WayOfDev\Serializer\Contracts\NormalizerRegistrationStrategy;
   // ...
   
   final readonly class CustomNormalizerRegistrationStrategy implements NormalizerRegistrationStrategy
   {
       public function __construct(
           private LoaderInterface $loader,
           private bool $debugMode = false,
       ) {
       }
   
       /**
        * @return iterable<array{normalizer: NormalizerInterface|DenormalizerInterface, priority: int<0, max>}>
        */
       public function normalizers(): iterable
       {
           // ...
       }
   }

2. Change serializer.php config to use your custom strategy:

   'normalizerRegistrationStrategy' => CustomNormalizerRegistrationStrategy::class,

To create a custom encoder registration strategy:

1. Implement the EncoderRegistrationStrategy interface:

   <?php
   
   declare(strict_types=1);
   
   namespace Infrastructure\Serializer;
   
   use Symfony\Component\Serializer\Encoder;
   use Symfony\Component\Serializer\Encoder\DecoderInterface;
   use Symfony\Component\Serializer\Encoder\EncoderInterface;
   use Symfony\Component\Yaml\Dumper;
   
   use function class_exists;
   
   final class CustomEncoderRegistrationStrategy implements Contracts\EncoderRegistrationStrategy
   {
       /**
        * @return iterable<array{encoder: EncoderInterface|DecoderInterface}>
        */
       public function encoders(): iterable
       {
           // Register your encoders here...
         
           yield ['encoder' => new Encoder\JsonEncoder()];
           yield ['encoder' => new Encoder\CsvEncoder()];
           yield ['encoder' => new Encoder\XmlEncoder()];
   
           if (class_exists(Dumper::class)) {
               yield ['encoder' => new Encoder\YamlEncoder()];
           }
       }
   }

2. Change serializer.php config to use your custom strategy:

   'encoderRegistrationStrategy' => CustomEncoderRegistrationStrategy::class,

The package provides a list of serializers that can be used to serialize and deserialize objects.

The default serializers available in this package are: symfony-json, symfony-csv, symfony-xml, symfony-yaml.

The SerializerManager handles the different serializers available in this package. It can be used to serialize and deserialize objects.

The ResponseFactory is used to create responses in Laravel controllers, making it easy to include serialized data in HTTP responses.

This package includes two Laravel Facades:

• Manager — To access the underlying SerializerManager
• Serializer — To access the bound and configured original Symfony Serializer instance.

We will use this example DTO for serialization purposes:

<?php

namespace Application\User;

use Symfony\Component\Serializer\Annotation\Groups;
use Symfony\Component\Serializer\Annotation\SerializedName;

class UserDTO
{
    #[Groups(['public'])]
    #[SerializedName('id')]
    private int $id;

    #[Groups(['public'])]
    #[SerializedName('name')]
    private string $name;

    #[Groups(['private', 'public'])]
    #[SerializedName('emailAddress')]
    private string $email;

    public function __construct(int $id, string $name, string $email)
    {
        $this->id = $id;
        $this->name = $name;
        $this->email = $email;
    }

    public function id(): int
    {
        return $this->id;
    }

    public function name(): string
    {
        return $this->name;
    }

    public function email(): string
    {
        return $this->email;
    }
}

<?php

namespace Application\Services;

use WayOfDev\Serializer\Manager\SerializerManager;
use Application\User\UserDTO;

class ProductService
{
    public function __construct(
        private readonly SerializerManager $serializer,
    ) {
    }

    public function someMethod(): void
    {
        $serializer = $this->serializer->serializer('symfony-json');
        $dto = new UserDTO(1, 'John Doe', '[email protected]');

        $serialized = $serializer->serialize(
            payload: $dto,
            context: ['groups' => ['private']]
        );
    }
}

Here's an example of how you can use the ResponseFactory in a Laravel Controller:

Example Controller:

<?php

namespace Bridge\Laravel\Public\Product\Controllers;

use Application\User\UserDTO;
use Illuminate\Http\Request;
use WayOfDev\Serializer\Bridge\Laravel\Http\HttpCode;
use WayOfDev\Serializer\Bridge\Laravel\Http\ResponseFactory;

class UserController extends Controller
{
    public function __construct(private ResponseFactory $response)
    {
    }

    public function index()
    {
        $dto = new UserDTO(1, 'John Doe', '[email protected]');

        $this->response->withContext(['groups' => ['private']]);
        $this->response->withStatusCode(HttpCode::HTTP_OK);
      
        return $this->response->create($dto);
    }
}

To switch from Laravel's default serialization to this implementation in queues, you can override the __serialize and __unserialize methods in your queue jobs. Here’s an example:

<?php

declare(strict_types=1);

namespace Bridge\Laravel\Public\Product\Jobs;

use Domain\Product\Models\Product;
use Domain\Product\ProductProcessor;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use WayOfDev\Serializer\Bridge\Laravel\Facades\Manager;

/**
 * This Job class shows how Symfony Serializer can be used with Laravel Queues.
 */
class ProcessProductJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    public Product $product;

    public function __construct(Product $product)
    {
        $this->product = $product;
    }

    public function handle(ProductProcessor $processor): void
    {
        $processor->process($this->product);
    }

    public function __serialize(): array
    {
        return [
            'product' => Manager::serialize($this->product),
        ];
    }

    public function __unserialize(array $values): void
    {
        $this->product = Manager::deserialize($values['product'], Product::class);
    }
}
