What is the Vue.js event bus and how do I use it?

The Vue.js event bus is a simple way to allow communication between components. It acts as a central hub for events.

Can you show me how to set it up in my Vue.js application?

Sure! First, create a new Vue instance that will serve as the event bus. You can do this in a separate file.

What does the code look like for that?

Here's a basic example: const EventBus = new Vue(); Then, you can use EventBus.$emit('eventName', data) to emit events and EventBus.$on('eventName', callback) to listen for them.

Are there any drawbacks to using the event bus?

Yes, while it's great for small applications, it can lead to difficulties in tracking events in larger apps. Consider Vuex for more complex state management.
