Vue EventBus to couple components loosely

Component.Vue

import EventBus from 'Events.js'

export default {
  ...
  mounted() {
    EventBus.$emit('eventName', payload);
  }
  ...
}

Events.js

import Vue from 'vue';

const EventBus = new Vue();

export default EventBus;

SomeOtherComponent.Vue

export default {
  ...
  mounted() {
    EventBus.$on('eventName', payload => {
      // do your thing
    }
  }
  ...
}
