Typed REST resources, validation, and OpenAPI generation for Laravel.

Resting is an alternative to Laravel's built-in API Resources, built around typed field objects. Each resource property is a strongly-typed Field that knows how to parse, validate, and format itself — so request payloads, validation rules, response shapes, and OpenAPI schemas all derive from a single source of truth.

class UserResource extends \Seier\Resting\Resource
{
    public StringField $name;
    public IntField $age;

    public function __construct()
    {
        $this->name = new StringField();
        $this->age = new IntField();
    }
}

Why Resting?

• One definition, many uses. A resource serves as the request schema, the validator, the response shape, and the OpenAPI component. No duplicated FormRequest + Resource + Swagger annotations.
• Strongly typed fields. Every field knows its own type, parser, and validators — no string-keyed validation rules to keep in sync with response transformers.
• Composable validation. Per-field validators, predicate-based conditional validation (whenProvided, whenEquals, …), and resource-level cross-field comparisons (lessThan, equal, …).
• Polymorphic resources. UnionResource for discriminator-tagged unions, DynamicResource for runtime field shapes.
• OpenAPI 3 out of the box. Generate a spec from your route collection with no extra annotations.

Requirements

• PHP 8.2+
• Laravel 11 or 12

Installation

composer require ebsp/resting

The service provider is auto-registered. Optionally publish the config:

php artisan vendor:publish --tag=config --provider="Seier\Resting\Support\Laravel\RestingServiceProvider"

Quickstart

Define a resource

use Seier\Resting\Resource;
use Seier\Resting\Fields\IntField;
use Seier\Resting\Fields\StringField;

class UserResource extends Resource
{
    public StringField $name;
    public IntField $age;

    public function __construct()
    {
        $this->name = (new StringField())->trim();
        $this->age = (new IntField())->required();
    }
}

Validate and parse a request

Route::post('/users', function (Request $request) {
    $user = (new UserResource())->set($request->all());

    // Persist…
    return $user;
});

Resource implements Laravel's Jsonable, so returning the resource is enough — Laravel encodes it as JSON automatically. Invalid input throws Illuminate\Validation\ValidationException with nested error paths.

Build a response

return (new UserResource())->set($model->toArray());

Or map a collection:

return (new UserResource())->mapMany(
    $users,
    fn (UserResource $r, User $u) => $r->set($u->toArray()),
);

Field types

All fields support required(), nullable(), forbidden(), and omittedDefault().

Conditional validation

Predicate factories let you express rules like "shippingAddress is required when requiresShipping is true":

use function Seier\Resting\Validation\Predicates\whenEquals;

public function __construct()
{
    $this->requiresShipping = new BoolField();
    $this->shippingAddress = (new StringField())
        ->required(whenEquals($this->requiresShipping, true));
}

Polymorphic resources

UnionResource discriminates between resource shapes by a tag field:

class AnimalResource extends UnionResource
{
    public function __construct()
    {
        parent::__construct('type', fn () => [
            'cat' => new CatResource(),
            'dog' => new DogResource(),
        ]);
    }
}

DynamicResource lets you build resources at runtime:

$resource = (new DynamicResource())
    ->withField('name', new StringField())
    ->withField('count', new IntField());

OpenAPI generation

Resting can produce an OpenAPI 3 document from your registered routes:

use Seier\Resting\Support\OpenAPI;

$spec = (new OpenAPI(Route::getRoutes()))->toArray();

Annotate routes with helper macros:

Route::post('/users', UserController::class)
    ->docs('Create a new user.')
    ->lists(UserResource::class);

Resources, query parameters, and route metadata are turned into components.schemas, components.parameters, and paths automatically.

Documentation

Full documentation, including all field types, validation predicates, the marshaller, and OpenAPI generation, is available at ebsp.github.io/resting (coming soon).
