I have a class decorated with attributes.

I would like to read the attributes in the constructor ( or other method ).

I have tried using Reflect and all possible methods on that class but I only get undefined

The class looks like this

@inject(Element)

@bindable('color')

export class Messagebarhost {



public element: HTMLElement;



  constructor(element) {

  console.log(Reflect.getMetadata("design:paramtypes", this));

  // prints undefined

  // somehow I want to read the value 'color'

  }

}

If I set a breakpoint in the bundled js file where the decorators are created. Below line will print the correct value if I enter it in the debugger

r.__metadata__.undefined["aurelia:resource"].properties[0]

I think you shouldn't put the decorator on the class but rather on a field as shown below:

@inject(Element)

export class Messagebarhost {



  public element: HTMLElement;

  @bindable color;





  constructor(element) {

     // this.color is not bound here yet.

  }



  attached () {

    // You need to wait till the attached or the bind function is

    // called to get the correct value in this.color.

  }

}
