How to call a component function if a data changes in store

Question

I want to trigger a method(serviceSelected) when state of a variable changes. I am trying to use computed but it is not working. My variable is in vuex store which is having a getter as getServiceSelected

computed: {
...mapGetters(["getServiceSelected"]),
serviceChanged() {

  this.serviceSelected(this.getServiceSelected);
  return this.getServiceSelected
}

}

Answer 1

Use watcher instead

computed: {
    ...mapGetters(["getServiceSelected"])
},
watch: {
    getServiceSelected(newValue, oldValue) {
        // do something
        this.serviceSelected(newValue);
    }
}
