Help! @Watch can not watch '$router' in Typecript

  @Watch('id')
  public getLinksFromRoute (val: any, old: any) {
     console.log(1); // worked
  }

  @Watch('$route')
  public getLinksFromRoute (val: Route, old: Route) {
     console.log(1); // not worked
  }

@Watch(‘$route’, { immediate: true, deep: true } ) onRouteChange (to: any, from: any) { console.log(to) this.photoId = to.params.id }

@CloseGillter47 It works if ‘deep’ is set to true. @Watch('$route', {deep: true})

@foxbunny What is recommended way to react to route changes?
