How can I implement an event bus in Vue 3 with TypeScript?

To implement an event bus in Vue 3 with TypeScript, you can create a simple event bus using an instance of Vue.

Can you show me a code example?

Sure! Here's a basic example:

import { createApp } from 'vue';

const EventBus = createApp({});

// Emitting an event
EventBus.config.globalProperties.$emit('my-event', data);

// Listening for an event
EventBus.config.globalProperties.$on('my-event', (data) => {
  console.log(data);
});

This sets up a global event bus.

What are the advantages of using an event bus?

Using an event bus allows for decoupled communication between components, making your application more modular and easier to maintain.
