Requirements

PHP 8.2 or higher
Laravel 11.0 or higher

Installation

You can install the package via Composer:

composer require holiq/action-data

The package will automatically register its service provider.

Optionally, you can publish the configuration file:

php artisan vendor:publish --provider="Holiq\ActionData\ActionDataServiceProvider" --tag="config"

After publishing, you can customize the paths in config/action-data.php:

return [
    'action_path' => 'app/Actions',
    'data_path' => 'app/DataTransferObjects',
];

Quick Start

Generate an Action with DTO:

php artisan make:action CreateUserAction --with-dto=CreateUserData

Define your DTO with validation:

readonly class CreateUserData extends DataTransferObject
{
    public function __construct(
        #[Required, Length(min: 2, max: 50)]
        public string $name,

        #[Required, Email]
        public string $email,
    ) {}
}

Implement your Action:

readonly class CreateUserAction extends Action
{
    public function execute(CreateUserData $data): User
    {
        return User::create($data->toArray());
    }
}

Use in your controller:

$userData = CreateUserData::resolve($request->validated())
    ->validateAttributes();

$user = CreateUserAction::resolve()->execute($userData);

Configuration

After publishing the configuration file, you can customize the paths where Actions and DTOs are generated:

// config/action-data.php
return [
    'action_path' => 'app/Actions',
    'data_path' => 'app/DataTransferObjects',
];

Usage

Generating Actions

Generate Actions using the Artisan command with various options:

# Basic action
php artisan make:action StoreUserAction

# Action in subdirectory
php artisan make:action User/StoreUserAction

# Action with auto-generated DTO
php artisan make:action StoreUserAction --with-dto=StoreUserData

# Force overwrite existing files
php artisan make:action StoreUserAction --force

Basic Action structure:

<?php

namespace App\Actions;

use Holiq\ActionData\Foundation\Action;

readonly class StoreUserAction extends Action
{
    public function execute(): mixed
    {
        // Your business logic here
    }
}

Action with DTO parameter:

<?php

namespace App\Actions;

use App\DataTransferObjects\StoreUserData;
use Holiq\ActionData\Foundation\Action;

readonly class StoreUserAction extends Action
{
    public function execute(StoreUserData $data): User
    {
        // Type-safe business logic with validated DTO
        return User::create($data->toArray());
    }
}

Generating DTOs

Generate DTOs using the Artisan command:

# Basic DTO
php artisan make:dto CreateUserData

# DTO in subdirectory
php artisan make:dto User/CreateUserData

# Force overwrite existing files
php artisan make:dto CreateUserData --force

Generated DTO structure:

<?php

namespace App\DataTransferObjects;

use Holiq\ActionData\Foundation\DataTransferObject;

readonly class CreateUserData extends DataTransferObject
{
    final public function __construct(
        // Define your properties with validation attributes
        // #[Required, Length(min: 1, max: 255)] public string $name,
        // #[Required, Email] public string $email,
    ) {}
}

Working with DTOs

Creating and Resolving DTOs

DTOs can be created from various data sources:

// From array
$userData = CreateUserData::resolve([
    'first_name' => 'John',
    'last_name' => 'Doe',
    'email' => '[email protected]'
]);

// From Form Request
$userData = CreateUserData::resolveFrom($request);

// From Eloquent Model
$userData = CreateUserData::resolveFrom($user);

Array Conversion

Convert DTOs to arrays with different formatting options:

readonly class CreateUserData extends DataTransferObject
{
    public function __construct(
        public string $firstName,
        public string $lastName,
        public string $email,
    ) {}
}

$data = new CreateUserData('John', 'Doe', '[email protected]');

// Convert to snake_case (default)
$array = $data->toArray();
// Result: ['first_name' => 'John', 'last_name' => 'Doe', 'email' => '[email protected]']

// Convert to camelCase
$camelCase = $data->toCamelCase();
// Result: ['firstName' => 'John', 'lastName' => 'Doe', 'email' => '[email protected]']

// Convert to JSON
$json = $data->toJson();

// Convert with context-specific exclusions
$createArray = $data->toArrayForCreate();
$updateArray = $data->toArrayForUpdate();

Property Exclusion

Control which properties are included in specific contexts:

readonly class CreateUserData extends DataTransferObject
{
    public function __construct(
        public string $firstName,
        public string $lastName,
        public string $email,
        public ?string $password = null,
    ) {}

    protected function toExcludedPropertiesOnCreate(): array
    {
        return []; // Include all properties for create
    }

    protected function toExcludedPropertiesOnUpdate(): array
    {
        return ['password']; // Exclude password from updates
    }
}

Validation

Laravel Action Data provides powerful validation through PHP attributes and custom callbacks.

Attribute-Based Validation

Use PHP attributes for declarative validation rules:

use Holiq\ActionData\Attributes\Validation\{Required, Email, Length, Range, Pattern};
use Holiq\ActionData\Foundation\DataTransferObject;

readonly class CreateUserData extends DataTransferObject
{
    public function __construct(
        #[Required, Length(min: 2, max: 50)]
        public string $name,

        #[Required, Email]
        public string $email,

        #[Required, Range(min: 18, max: 120)]
        public int $age,

        #[Pattern(regex: '/^\+?[1-9]\d{1,14}$/')]
        public ?string $phone = null,
    ) {}
}

// Validate using attributes
try {
    $user = CreateUserData::resolve($data);
    $user->validateAttributes();
    // DTO is valid
} catch (\InvalidArgumentException $e) {
    // Handle validation errors
    echo $e->getMessage();
}

Available validation attributes:

#[Required] - Field cannot be null, empty string, or empty array
#[Email] - Validates email format
#[Length(min: int, max: int)] - Validates string length
#[Range(min: int|float, max: int|float)] - Validates numeric ranges
#[Pattern(regex: string)] - Validates against regular expression

Custom Validation Callbacks

Use custom validation logic with chainable callbacks:

$user = new CreateUserData('John Doe', '[email protected]', 25);

// Single validation
$user->validate(
    fn (CreateUserData $data) => str_contains($data->email, '@'),
    'Email must contain @ symbol'
);

// Chain multiple validations
$user
    ->validate(fn ($data) => !empty($data->name), 'Name is required')
    ->validate(fn ($data) => $data->age >= 18, 'Must be adult')
    ->validateAttributes(); // Combine with attribute validation

Nested DTOs

Laravel Action Data automatically resolves nested DTOs and arrays of DTOs:

Simple Nested DTOs

readonly class AddressData extends DataTransferObject
{
    public function __construct(
        public string $street,
        public string $city,
        public string $country,
    ) {}
}

readonly class UserData extends DataTransferObject
{
    public function __construct(
        public string $name,
        public string $email,
        public AddressData $address, // Nested DTO
    ) {}
}

// Automatically resolves nested structure
$user = UserData::resolve([
    'name' => 'John Doe',
    'email' => '[email protected]',
    'address' => [
        'street' => '123 Main St',
        'city' => 'Anytown',
        'country' => 'USA',
    ],
]);

// Access nested data
echo $user->address->street; // "123 Main St"

Arrays of DTOs

readonly class UserData extends DataTransferObject
{
    public function __construct(
        public string $name,
        public AddressData $currentAddress,
        /** @var AddressData[] */
        public array $previousAddresses = [], // Array of DTOs
    ) {}
}

$user = UserData::resolve([
    'name' => 'Jane Smith',
    'currentAddress' => [
        'street' => '456 Oak Ave',
        'city' => 'Springfield',
        'country' => 'USA',
    ],
    'previousAddresses' => [
        [
            'street' => '789 Pine St',
            'city' => 'Oldtown',
            'country' => 'USA',
        ],
        [
            'street' => '321 Elm Dr',
            'city' => 'Hometown',
            'country' => 'USA',
        ],
    ],
]);

// Access array of DTOs
foreach ($user->previousAddresses as $address) {
    echo $address->street; // Each item is an AddressData instance
}

Data Transformations

Apply automatic data transformations during DTO resolution to clean and format your data:

readonly class UserProfileData extends DataTransferObject
{
    public function __construct(
        public string $name,
        public string $email,
        public ?string $bio = null,
        public int $age = 0,
    ) {}

    /**
     * Define transformations applied during resolve()
     */
    protected static function transforms(): array
    {
        return [
            'name' => fn ($value) => trim(strtoupper($value)),
            'email' => fn ($value) => trim(strtolower($value)),
            'bio' => fn ($value) => $value ? trim($value) : null,
            'age' => fn ($value) => max(0, (int) $value), // Ensure non-negative
        ];
    }
}

$profile = UserProfileData::resolve([
    'name' => '  john doe  ',           // Becomes "JOHN DOE"
    'email' => '  [email protected]  ',  // Becomes "[email protected]"
    'bio' => '  Software developer  ',   // Becomes "Software developer"
    'age' => '-5',                       // Becomes 0
]);

Complex transformations example:

readonly class ProductData extends DataTransferObject
{
    public function __construct(
        public string $name,
        public float $price,
        /** @var string[] */
        public array $tags,
    ) {}

    protected static function transforms(): array
    {
        return [
            'name' => fn ($value) => ucwords(trim($value)),
            'price' => fn ($value) => round((float) $value, 2),
            'tags' => fn ($value) => is_array($value)
                ? array_values(array_map('strtolower', array_filter($value)))
                : [],
        ];
    }
}

$product = ProductData::resolve([
    'name' => '  awesome widget  ',    // Becomes "Awesome Widget"
    'price' => '19.999',               // Becomes 20.0
    'tags' => ['Electronics', '', 'GADGET', null, 'Popular'], // Becomes ["electronics", "gadget", "popular"]
]);
