Feature: eventBus

Hi! In Vue3, vue instance no longer implement the event emitter interface.

So eventBus will no longer be available.

import Vue from 'vue';
const bus = new Vue();

bus.$on('xxx', '...');
bus.$emit('xxx', '...');

there’s a way to implement this event emitter/pubsub feature by composition-api?

Thank you, I’ll just do it on my own project.

I still recommend using mitt, as I can’t do any better than it. If you do ask for this feature anyway, the best solution I can have is to make a plugin @vueuse/mitt (which is basically the code I showed above). And it would still require you to install mitt.
