React PropTypes: Allow different types of PropTypes for one prop

React PropTypes: Allow Different Types of PropTypes for One Prop 😎🔤💯

So, you have a React component that receives a prop called size. And you're wondering, can you let React.PropTypes know that this prop can be either a string or a number? 🤔

Well, the answer is yes! You can definitely achieve this using React PropTypes with a small tweak to your propTypes validation. Let me show you how! 🚀

The Warning Message 👀🚨

When you don't specify the type in your propTypes validation, you encountered a warning message:

prop type size is invalid; it must be a function, usually from React.PropTypes.

This warning occurs because React.PropTypes expects a function to be set as the prop type, not the React.PropTypes object itself.

Solution: One Func to Rule Them All 🛠🔢✨

To address this issue and allow different types for the size prop, you'll use the function provided by React.PropTypes to define the prop type.

MyComponent.propTypes = {
    size: React.PropTypes.oneOfType([
        React.PropTypes.string,
        React.PropTypes.number
    ])
}

By using React.PropTypes.oneOfType, you can create an array of valid types for the size prop. In this case, the size prop can be either a string or a number. 🌟

Complete Example 🌈🎉

To put it all together, here's a complete example of how your propTypes validation should look like:

import React from 'react';
import PropTypes from 'prop-types';

class MyComponent extends React.Component {
    // Component code here
}

MyComponent.propTypes = {
    size: PropTypes.oneOfType([
        PropTypes.string,
        PropTypes.number
    ])
}

export default MyComponent;

Time to Engage! 📢🙌

Now that you know how to allow different types for a single prop using React PropTypes, it's time to put it into practice! Update your code, test it out, and see the magic happen! ✨🔮
