Is there something like JSON scalar type ?

[scion4581]

Hello!
In some cases, a response could have an unknown count of fields and even nested ones.
Is there something like JSON scalar type?
Thanks

Hi. It's quite easy to make your own.
Here is an example with attributes:

<?php

declare(strict_types=1);

namespace App\GraphQL\Scalar;

use GraphQL\Language\AST\BooleanValueNode;
use GraphQL\Language\AST\FloatValueNode;
use GraphQL\Language\AST\IntValueNode;
use GraphQL\Language\AST\ListValueNode;
use GraphQL\Language\AST\ObjectValueNode;
use GraphQL\Language\AST\StringValueNode;
use Overblog\GraphQLBundle\Annotation as GQL;

#[GQL\Scalar]
#[GQL\Description('Json scalar type')]
class Json
{
    public static function serialize($value)
    {
        return $value;
    }

    public static function parseValue($value)
    {
        return $value;
    }

    public static function parseLiteral($valueNode)
    {
        switch ($valueNode) {
            case $valueNode instanceof StringValueNode:
            case $valueNode instanceof BooleanValueNode:
                return $valueNode->value;
            case $valueNode instanceof IntValueNode:
            case $valueNode instanceof FloatValueNode:
                return \floatval($valueNode->value);
            case $valueNode instanceof ObjectValueNode:
                    $value = [];
                    foreach ($valueNode->fields as $field) {
                        $value[$field->name->value] = self::parseLiteral($field->value);
                    }

                    return $value;

            case $valueNode instanceof ListValueNode:
                return \array_map([self, 'parseLiteral'], $valueNode->values);
            default:
                return null;
        }
    }
}
