如何在我的 React linter 中修复“声明的道具类型中的错字：标题”？

Question

I'm currently using ESLint, Airbnb lint, and Prettier to control code styling. I'm getting an error in the header.propTypes title below. I've looked at the documentation but I'm not understanding the solution. This is a React project.

The error is:

Typo in declared prop type: title

What am I doing wrong here?

export default function Header(props) {
  const { title } = props;
  return (
    <Helmet>
      <title>{title}</title>
    </Helmet>
  );
}

Header.propTypes = {
  title: PropTypes.title.isRequired
};

Answer 1

The RHS is invalid, PropTypes.title.isRequired . You probably mean to have PropTypes.string.isRequired .
