type missing when using static propTypes
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I don't know what's happening...
when I use static propTypes in a class component.It turns out that type is missing.
type IProps = {
title: string;
} & ReturnType<typeof mapStateToProps>
class Test extends PureComponent<IProps> {
static propTypes = {
}
render() {
const { title } = this.props;
return (
<div>hello world! {title}</div>
)
}
}
const mapStateToProps = (state: any) => {
return {
state
}
}
export default connect(mapStateToProps)(Test);
Error message:
[ts]
Argument of type 'typeof Test' is not assignable to parameter of type 'ComponentType<never>'.
Type 'typeof Test' is not assignable to type 'ComponentClass<never, any>'.
Types of property 'propTypes' are incompatible.
Type '{}' is not assignable to type 'undefined'. [2345]

Usually there's no need to use propTypes with TS because they serve a similar purpose.

That's right, but how should I define the type correctly? Thank you very much anyway.

The following compiles for me. I haven't tested that the validation does what you intend at runtime.
import * as PropTypes from "prop-types";
// ...
static propTypes = {
title: PropTypes.string.isRequired,
state: PropTypes.any
}
It still does not work as the type is missing.
