Typescript: How to extend two classes?

Question

I want to save my time and to reuse common code across classes which extends PIXI classes (a 2d webGl renderer library).

Object Interfaces:

Answer 1

TypeScript supports decorators, and using that feature plus a little library called typescript-mix you can use mixins to have multiple inheritance with just a couple of lines

// The following line is only for intellisense to work
interface Shopperholic extends Buyer, Transportable {}

class Shopperholic {
  // The following line is where we "extend" from other 2 classes
  @use( Buyer, Transportable ) this 
  price = 2000;
}
