create-react-app doesn't apply eslint rules that are in place like `button-has-type` and `boolean-prop-naming`

Question

I have generated a React app using create-react-app . The generated app comes with eslint and eslint rules like button-has-type and boolean-prop-naming . However, when I run npm start , I don't see any errors that am expecting.

Using above eslint rules I expect the following code to fail

<button>Hello</button>

and

App.propTypes = {
   enabled: PropTypes.bool
};

Thanks

you can install npm i -s prop-types and use prop-types.

import { PropTypes } from 'prop-types';

App.propTypes = {
   enabled: PropTypes.bool
};
