I have a React Wrapper Component, that accepts some props, but forwards all others to the child component (especially relevent for native props like className, id, etc.).
Typescript complains, however, when I pass native props. See error message:
TS2339: Property 'className' does not exist on type 'IntrinsicAttributes & IntrinsicClassAttributes< Wrapper > & Readonly< { children?: ReactNode; }> & Readonly< WrapperProps>'.
How can I get a component with specific props that also accepts native props (without accepting any props and giving up on type checking)?
My code looks like this:
interface WrapperProps extends JSX.IntrinsicAttributes {
callback?: Function
}
export class Wrapper extends React.Component<WrapperProps>{
render() {
const { callback, children, ...rest } = this.props;
return <div {...rest}>
{children}
</div>;
}
}
export const Test = () => {
return <Wrapper className="test">Hi there</Wrapper>
}
FYI: I found a similar question here, but the answer basically gives up type checking, which I want to avoid: Link to SO-Question
We can have a look at how div
props are defined:
interface IntrinsicElements {
div: React.DetailedHTMLProps<React.HTMLAttributes<HTMLDivElement>, HTMLDivElement>;
}
If we use React.DetailedHTMLProps<React.HTMLAttributes<HTMLDivElement>, HTMLDivElement>
as the base type we will have all properties of div
. Since DetailedHTMLProps
just adds ref
to React.HTMLAttributes<HTMLDivElement>
we can use just this as the base interface to get all div
properties:
interface WrapperProps extends React.HTMLAttributes<HTMLDivElement> {
callback?: Function
}
export class Wrapper extends React.Component<WrapperProps>{
render() {
const { callback, children, ...rest } = this.props;
return <div {...rest}>
{children}
</div>;
}
}
export const Test = () => {
return <Wrapper className="test">Hi there</Wrapper> // works now
}
