How can I implement custom validation for Vue prop types?

How can I implement custom validation for Vue prop types?

You can create custom validators by defining a function that checks the prop value and returns true or an error message.

Can you show me an example of a custom validator?

Sure! Here's a simple example:

props: {
  age: {
    type: Number,
    validator: function(value) {
      return value >= 18;
    }
  }
}

This validator checks if the age is 18 or older.

What happens if the validation fails?

If the validation fails, Vue will log a warning in the console, and the component will not receive the invalid prop.

Can I use multiple validators for a single prop?

Yes, you can use an array of validators for a single prop. Each validator will be called in order until one fails.
