TIL #4 - You can use this.$root as a Vue eventbus

I don't know how I'm only just realizing this but since this.$root is a Vue instance you can use it as an eventbus to communicate between components. Before today, I'd been manually creating every single eventbus I've ever used, when I did not have to, thanks to an eventbus tutorial I read years ago.

What I was doing:

// eventbus.js
export default new Vue({});

// main.js
import eventbus from "../utils/eventbus";
Vue.prototype.$eventbus = eventbus;

// Banks.vue
this.$eventbus.$on("token-set", this.getBanks);
this.$eventbus.$emit("token-set");

What I'm doing and what you should be doing:

// Banks.vue
this.$root.$on("token-set", this.getBanks);
this.$root.$emit("token-set");

Hopefully this prevents you from losing several minutes of your precious time on earth to unnecessarily manually implementing an eventbus. 😂
