Render output based on content-type

Render an array (or HAL object) to a JSON/XML/HTML PSR-7 Response based on a PSR-7 Request's Accept header.

Installation

composer require akrabat/rka-content-type-renderer

Usage

// given:
// $request instanceof Psr\Http\Message\RequestInterface
// $response instanceof Psr\Http\Message\ResponseInterface

$data = [
    'items' => [
        [
            'name' => 'Alex',
            'is_admin' => true,
        ],
        [
            'name' => 'Robin',
            'is_admin' => false,
        ],
    ],
];
$renderer = new RKA\ContentTypeRenderer\Renderer();
$response  = $renderer->render($request, $response, $data);
return $response->withStatus(200);

The constructor takes a parameter, $pretty that defaults to true. Set to false to disable pretty printing.

HalRenderer

This component also supports nocarrier/hal objects with the HalRenderer:

$hal = new Nocarrier\Hal(
    '/foo',
    [
        'items' => [
            [
                'name' => 'Alex',
                'is_admin' => true,
            ],
            [
                'name' => 'Robin',
                'is_admin' => false,
            ],
        ],
    ]
);
$renderer = new RKA\ContentTypeRenderer\HalRenderer();
$response  = $renderer->render($request, $response, $hal);
return $response->withStatus(200);

ApiRenderer

This component also supports crell/ApiProblem objects with the ApiProblemRenderer:

$problem = new Crell\ApiProblem("Something unexpected happened");
$renderer = new RKA\ContentTypeRenderer\ApiProblemRenderer();
$response  = $renderer->render($request, $response, $problem);
return $response->withStatus(500);

Arrays of objects

If you have an array of objects, then the renderer will still work as long as the objects implement PHP's JsonSerializable interface.
