Hello

I try to write modules by supporting PSR7, just a question from JSON output in handler, which one is correct?

Simple output by JsonResponse

```auto
        $result = [
            'result' => true,
            'data' => $account,
            'error' => '',
        ];

        return new JsonResponse($result);

```

Or use PSR responseFactory

```auto
        $result = [
            'result' => true,
            'data' => $account,
            'error' => '',
        ];

        $result = json_encode($result);
        $response = $this->responseFactory->createResponse(200)->withHeader('Content-Type', 'application/json');
        $response->getBody()->write($result);
        return $response;

```

Or `JsonResponse` is a child of PSR `responseFactory`?

Thanks

The [custom response](https://docs.laminas.dev/laminas-diactoros/v2/custom-responses/) class for JSON implements `Psr\Http\Message\ResponseInterface` and is a class of laminas-diactoros.

The factory implements `Psr\Http\Message\ResponseFactoryInterface` but is also a class of laminas-diactoros.

No:

Therefore, choose the option that is easier for you. And if you want to change the PSR-7 and PSR-17 library later, that works quite easily for both variants.

Thank you very much. I choose `JsonResponse` for our modules
