Stop receiving events from destroyed child component

Question

I have a parent where I can dynamically add child components into.

When child component is added in mount I register a listener for an event

EventBus.$on         


        

Answer 1

another solution without creating component method

mounted(){
  const listener = () => {
    // heavy logic
  };

  EventBus.$on('content-type-saving', listener);

  this.$once("hook:beforeDestroy", () => {
     EventBus.$off('content-type-saving', listener);
  });
}
