How can I use advanced prop types in Vue 3?

In Vue 3, you can define advanced prop types using the defineProps function. This allows you to specify types, default values, and even custom validators.

Can you give me an example of using a custom validator?

Sure! You can define a prop with a custom validator like this:

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

What happens if the validation fails?

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

Are there any built-in validators I can use?

Yes, Vue provides built-in validators like type, required, and you can also create your own custom validators for more complex logic.
