Prefer to forbid certain propTypes JS-0398
Prop type "object" is forbidden
30
31MyApp.propTypes = {
32 Component: PropTypes.func,
33 pageProps: PropTypes.object,34};
35
36export default MyApp;
Description
This issue prevents the use of vague prop types with more specific alternatives available (any, array, object).
The defaults are chosen because they have obvious replacements. any should be replaced with, well, anything. array and object can be replaced with arrayOf and shape, respectively.
Bad Practice
const Component = createReactClass({
propTypes: {
a: PropTypes.any,
r: PropTypes.array,
o: PropTypes.object
},
// ...
});
class Component extends React.Component { /* ... */ }
Component.propTypes = {
a: PropTypes.any,
r: PropTypes.array,
o: PropTypes.object
};
class Component extends React.Component {
static propTypes = {
a: PropTypes.any,
r: PropTypes.array,
o: PropTypes.object
}
render() {
return <div />;
}
}
Recommended
function Component(props) {
// ...
}
Component.propTypes = {
a: PropTypes.arrayOf(PropTypes.number)
}
