Can I wrap an observable returned from mobx?

[burtonator]

I have an observable I'm using in an observer. however, I want to wrap it so that I can override some of the behavior as I'm building an undo/redo store.

Will the observer work with the observable even though it's wrapped now?

Wrapping is a pretty vague term, I'm not sure what you mean by it. But, just try it first in a small experiment?

Let's say I have an observable with an @computed method...

so it's has a getMessage() and a setMessage method

I then create a wrapped version that has an internal instance variable of the original that I delegate methods to.

so somethign like

class FooInstance {
   constructor(private readonly delegate: MainInstance);

  public setMessage(message: string) {
    this.delegate.setMessage(message);
  } 

  public getMessage() {
    return this.delegate.getMessage();
  } 

}

... something like that.

Yeah no problem, MobX will track through that.
