Slim, Mezzio & any PSR-7 framework

For frameworks built on PSR-7 (Slim, Mezzio/Laminas, Chubbyphp, custom middlewares) the integration is a single line at the edge: PSR-7 gives you arrays, and from() takes arrays.

Setup

// bootstrap
use StdOut\SimpleDataObjects\Support\MetadataRegistry;

MetadataRegistry::setStoragePath(__DIR__.'/../var/cache/data-objects');

Request handling

use Psr\Http\Message\ServerRequestInterface as Request;
use Psr\Http\Message\ResponseInterface as Response;

$app->post('/orders', function (Request $request, Response $response) {
    $order = OrderData::fromValidated((array) $request->getParsedBody());

    $response->getBody()->write($order->toJson());

    return $response->withHeader('Content-Type', 'application/json');
});

Query parameters work the same way:

$filters = SearchFilterData::from($request->getQueryParams());

For a raw JSON body without a body-parsing middleware, pass the string straight in — from() decodes it:

$order = OrderData::from((string) $request->getBody());

Validation

#[Rules] validation runs standalone (see Validation) — fromValidated() throws Illuminate\Validation\ValidationException, which your error middleware can map to a 422 response:

$app->addErrorMiddleware(...)->getDefaultErrorHandler();
// map ValidationException::errors() to your problem-details format
