In pixijs project, i want to create class component that extends Spine, but it gives me an error “Uncaught Error: The spineData param is required.”

Here is an example:

export class TargetView extends Spine {
  constructor() {
    super();
    this.spineData = RESOURCES.getSpineData("shooting");
  }
}

I tried to pass spineData when creating class

target = new TargetView("spinedata);
