How to correctly structure and validate complex data structure

[TimmyBravo]

Hello,

I recently found this package and started implementing it as a way to combine resources, requests, validation rules and more into a single class. I have a pretty large and complex data structure with a lot of conditional logic.

I have many cases where the available enum options differs depending on another value in the same data class or possibly even in the parent.

enum CustomEnum: string {
    case case1 = 'case_1';
    case case2 = 'case_2';
}

enum CustomEnum2: string {
    case case3 = 'case_3';
    case case4 = 'case_4';
}

class Parent extends Data {
    public function __construct(
        public string $uid,
        public string $type,
        public CustomEnum|CustomEnum2 $prop,
        public Child $childValues,
    ) {
    }
}

class Child extends Data {
    public function __construct(
        public int $val1,
        public int $val2.
        public int $val3
    ) {
    }
}

Based on the simplified example above I need the following logic:

1. $parent->prop can be anything in CustomEnum if $parent->type is 'X' but must be anything in CustomEnum2 if $parent->type is 'Y'
2. $childValues->val3 is required if $parent->type is 'X' but shouldn't exist if $parent->type is 'Y'

Another more advanced example is that the available enum options can differ based on multiple other input values.

I would also like to set this up in a way that allows the TypeScript generator to understand the conditional logic that is applied if possible

Is it possible to achieve this logic without too much custom code? How would I go about achieving this?
