How do props and events work in Vue 3?

How do props and events work in Vue 3?

In Vue 3, props are used to pass data from a parent component to a child component, while events are used to communicate from the child back to the parent.

Can you give me an example of using props?

Sure! You can define a prop in a child component like this: props: { message: String }, and then pass it from the parent like this: <ChildComponent :message='"Hello!"' />.

What about events? How do I emit an event from a child?

You can emit an event in a child component using this.$emit('eventName', data). The parent can listen for this event using @eventName='handler'.

Are there any best practices for using props and events?

Yes! Keep props as simple as possible, avoid mutating them in child components, and use events to communicate changes back to the parent.
