How do I use emit in Vue 3 with TypeScript?

In Vue 3, you can use the emit function to create custom events. In TypeScript, you can define the event types for better type safety.

Can you show me an example of how to define event types?

Sure! You can define an interface for your event payload and use it with the emit function. For example:

interface MyEvent {
  message: string;
}

this.$emit<MyEvent>('my-event', { message: 'Hello!' });

What if I want to listen to multiple events?

You can listen to multiple events by using the v-on directive in your template. For example:

<my-component @my-event='handleMyEvent' @another-event='handleAnotherEvent' />

Is there a way to type the component's props as well?

Yes! You can define props using the defineProps function in your component. This allows you to specify types for your props.
