The Power of Vue EventBus and Understanding the Lifecycle

How can I trigger an event in one component using an event from another? I have two child components at the same level, and when the updated() method is called in component1.vue, I want the setValues() method in component2.vue to be triggered.

In component2.vue, this is what I currently have within the created hook:

created() {
      EventBus.$on('updatedComponent', () => {
          this.setValues();
      });
}

And in the updated() method of component1.vue:

EventBus.$emit('updatedComponent');

I have already imported the event bus in both components, and it seems to work (I tested with a console log inside the $on) but the events are still not triggering. Do I need to place my EventBus.$on in a different lifecycle hook?

Answer №1

It appears that the issue you are facing is with initializing the updated() function. Ensure to update the view in order to activate the updated() function.
