How do I use PropTypes in Vue.js?

How do I use PropTypes in Vue.js?

In Vue.js, you can use the prop option in your component to define the expected types of props. However, Vue does not have built-in PropTypes like React. Instead, you can use the type property to specify the type of each prop.

Can you give me an example of how to define props with types?

Sure! Here's a simple example:

export default {
  props: {
    name: {
      type: String,
      required: true
    },
    age: {
      type: Number,
      default: 18
    }
  }
}

What happens if I pass the wrong type?

If you pass a prop of the wrong type, Vue will issue a warning in the console during development, but it won't prevent your app from running.

Is there a way to validate props more strictly?

Yes, you can create custom validators for props. You can define a validator function within the prop definition to enforce stricter validation.
