What are the best practices for using PropTypes in Vue CLI?

Using PropTypes in Vue CLI helps ensure that your components receive the correct data types. Best practices include defining PropTypes for all props, using default values, and leveraging custom validators for complex types.

Can you give me an example of how to define PropTypes in a Vue component?

Sure! In a Vue component, you can define PropTypes like this:

export default {
  props: {
    title: {
      type: String,
      required: true,
      default: 'Default Title'
    },
    age: {
      type: Number,
      validator: value => value > 0
    }
  }
};

What happens if a prop doesn't match the defined PropType?

If a prop doesn't match the defined PropType, Vue will issue a warning in the console during development, helping you catch potential issues early.

Are there any tools to help with PropTypes validation?

Yes, tools like Vue PropTypes and Vue.js devtools can assist in validating and debugging PropTypes in your Vue applications.
