PropTypes in functional stateless component

Question

Without using class, how do I use PropTypes in functional stateless component of react?

export const Header = (props) => (
   
hi
)
         


        

Answer 1

It isn't different with the stateful, You can add it like:

import PropTypes from 'prop-types';
Header.propTypes = {
  title: PropTypes.string
}

Here is a link to prop-types npm
