How can I create custom prop types in Vue 3?

How can I create custom prop types in Vue 3?

In Vue 3, you can create custom prop types by defining a validator function in the props option of your component.

Can you show me an example of a custom prop type?

Sure! Here's a simple example:

props: {
  myProp: {
    type: String,
    validator: function(value) {
      return value.length > 0; // Must be a non-empty string
    }
  }
}

What happens if the prop validation fails?

If the prop validation fails, Vue will issue a warning in the console during development, but it won't stop the component from rendering.

Can I use multiple validators for a single prop?

Yes, you can combine multiple validators by returning true only if all conditions are met within the validator function.
