Is the Vue.js global event bus OK?

Question

Vue.js

Is it normal practice to use the event bus globally in large projects?
app.js:

import Vue from 'vue'

Vue.prototype.$bus = new Vue()

new Vue({
  el: '#app',
})

Answer 1

Instead of an event bus, it's better to use Vuex

Answer 2

No, this is a miserable anti-pattern that you need to run away from.

Answer 3

This thing has been deprecated for several years now .

Answer 4

If you ignore the witch hunt, then you should use the event bus when events are needed . If you need a state and its change - the event bus is really an antipattern, but in this case.
However, option c, bus = new Vue()although simple, is fraught with memory leaks. It is better to make the bus through a global mixin, which, on destroy, will automatically clear all listeners of a particular component.
