Why doesn't RequestBodyParserMiddleware support application/json?

[CodeWithKyrian]

I've been working with the HTTP server recently and noticed something that made me curious. While implementing API endpoints, I had to write custom middleware to parse JSON request bodies.

Looking through the codebase, I found the RequestBodyParserMiddleware already handles:

• application/x-www-form-urlencoded
• multipart/form-data

But it doesn't have support for application/json, which is pretty much the standard for modern APIs.

I'm wondering if this was an intentional design decision? Is there a specific reason JSON parsing was left out, or is it expected that developers implement this themselves?

Something as simple as:

if ($type === 'application/json') {
    $data = json_decode((string)$request->getBody(), true);
    return $next($request->withParsedBody($data));
}

Would be really helpful for API-focused applications.

Just curious about the thought process here.

I'm just gonna close this cos I found this: reactphp/http#306 and it seems it was actually intentional.
