How can I validate props in Vue 3 using PropTypes?

In Vue 3, you can validate props using the defineProps function along with TypeScript or by using PropTypes. Would you like an example?

Yes, please provide an example of using PropTypes for prop validation.

Sure! First, install PropTypes with npm. Then, you can define your component like this:

import PropTypes from 'prop-types';

export default {
  props: {
    myProp: {
      type: String,
      required: true,
    },
  },
};

This will ensure myProp is a required string.

What if I want to validate multiple props?

You can define multiple props in the same way. Just add them to the props object:

props: {
  myString: { type: String, required: true },
  myNumber: { type: Number, default: 0 },
  myArray: { type: Array, default: () => [] },
},

This validates a string, a number with a default value, and an array.
