Get all getters results as class variables without specific invoking

Is there a way I can get all the getters results on the instance without specific invoking?
I want to get all class getters as simple members on the class by looping on the class member.

I have a class like this:

export class Test {
  constructor() {}

  get foo() {
    return 1
  }

  get bar() {
    return 2
  }
}

The use is create a new instance: const test = new Test()

Is there a way I can get all the getters as simple class variable members and not as functions? so I can pass the object from server to client.

Thanks!
