Property change subscription with Aurelia

Question

I have a property on my viewmodel which I want to listen to and trigger events based on its value, like this:

class viewModel {
  constructor() {
    this.va         


        

Answer 1

listen to and trigger events based on its value

A snippet from code using TypeScript, hopefully that will get you an idea:

import {bindingMode} from "aurelia-binding";

export class Example{

    @bindable
    public description: string;

    private descriptionChanged(newValue: string, oldValue: string): void {
        console.log(newValue, oldValue);
    }
}

Method name should follow convention `${propertyName}Changed`
