$args as an object

[Afrowson]

I was working on making a previously required ID optional for a specific mutation. When i adjusted everything, i wrote a test with NULL as ID but it obviously failed when the frontend omited the ID while sending it. Lighthouse andled everything well, but in my code it did break because i cant array access a key that does not exist...

If the $args passed to the resolver would be an object like a Request or Collection, this could be handled gracefully by simply returning null for a missing key... If the Interrest for such a solution exists, i would be willing to invest some time in to it.

I use PHPStan array shapes to type $args, this allows static analysis to ensure accesses are safe.

/** @param array{id?: ?string} */
public function __invoke(null $_, array $args): ...

Note the two ?, optional arguments in GraphQL can be null or omitted.

Also, have you considered $args['id'] ?? null?
