Use PHP enums for GraphQL enums

[socivdias]

To create an enum for a GraphQL type we need to create a class and extend EnumType. Would it be possible to use PHP enums instead?

Yes, make a regular Rebing\GraphQL\Support\EnumType and in its toType() method return a

return new GraphQL\Type\Definition\PhpEnumType(<your enum clas>::class, '<name of enum>');

This should do it.

See https://webonyx.github.io/graphql-php/type-definitions/enums/#construction-from-php-enum what you can do on your enum to support GraphQL (description and stuff), this works too.

Reminds that such an example should be added to the readme...

So, basically, I'd need something like the following under types in my graphql.php file, right?

'myEnumName' => new class extends \Rebing\GraphQL\Support\EnumType {
    public function toType(): \GraphQL\Type\Definition\Type
    {
	    return new \GraphQL\Type\Definition\PhpEnumType(<my enum clas>::class, 'myEnumName');
    }
},
