— From boring old arrays to shiny typed objects —

Valinor takes care of the construction and validation of raw inputs (JSON, plain arrays, etc.) into objects, ensuring a perfectly valid state. It allows the objects to be used without having to worry about their integrity during the whole application lifecycle.

The validation system will detect any incorrect value and help the developers by providing precise and human-readable error messages.

The mapper can handle native PHP types as well as other advanced types supported by PHPStan and Psalm like shaped arrays, generics, integer ranges and more.

The library also provides a normalization mechanism that can help transform any input into a data format (JSON, CSV, …), while preserving the original structure.

Installation

Example

final class Country
{
    public function __construct(
        /** @var non-empty-string */
        public readonly string $name,
        
        /** @var list<City> */
        public readonly array $cities,
    ) {}
}

final class City
{
    public function __construct(
        /** @var non-empty-string */
        public readonly string $name,
        
        public readonly DateTimeZone $timeZone,
    ) {}
}

$json = <<<JSON
    {
        "name": "France",
        "cities": [
            {"name": "Paris", "timeZone": "Europe/Paris"},
            {"name": "Lyon", "timeZone": "Europe/Paris"}
        ]
    }
JSON;

try {
    $country = (new \CuyZ\Valinor\MapperBuilder())
        ->mapper()
        ->map(Country::class, \CuyZ\Valinor\Mapper\Source\Source::json($json));

    echo $country->name; // France 
    echo $country->cities[0]->name; // Paris
} catch (\CuyZ\Valinor\Mapper\MappingError $error) {
    // Handle the error…
}
