Installation

Mapper package is available as Composer repository and can be installed using the following command in a root of your project:

composer require type-lang/mapper

Quick Start

use TypeLang\Mapper\Mapping\MapType;

class ExampleObject
{
    public function __construct(
        #[MapType('list<non-empty-string>')]
        public readonly array $names,
    ) {}
}

$mapper = new \TypeLang\Mapper\Mapper();

$result = $mapper->normalize(
    new ExampleObject(['Example'])
);
// Expected Result:
//
// array:1 [
//   "names" => array:1 [
//     0 => "Example"
//   ]
// ]


$result = $mapper->denormalize([
    'names' => ['first', 'second']
], ExampleObject::class);
// Expected Result:
//
// ExampleObject {#324
//   +names: array:2 [
//     0 => "first"
//     1 => "second"
//   ]
// }


$result = $mapper->denormalize([
    'names' => ['first', 'second', ''],
], ExampleObject::class);
// Expected Result:
//
// InvalidFieldTypeValueException: Passed value of field "names" must be of type
//   list<non-empty-string>, but array(3)["first", "second", ""] given at $.names[2]

Benchmarks

Results here like this.

Sample: An object that contains a collection of objects, which contains another collection of objects.

ExampleObject {
    name: string,
    items: list<ExampleObject>
}

The results are sorted by mode time.

Denormalization

Denormalization: Transformation from raw payload (array) to concrete object.
