How To Create A Ref Using Typescript And Styled-components

- 1 answer

I'm trying to add a ref to React component like this:

const Dashboard: React.FC = () => {
  const [headerHeight, setHeaderHeight] = useState(0);

  const headerRef = React.createRef<HTMLInputElement>();
  useEffect(() => {
    // @ts-ignore: Object is possibly 'null'
    setHeaderHeight(ref.current.clientHeight)
  });

  return (
    <Root>
      <Header ref={headerRef} />

      <div>other contents</div>             
    </Root>
  );
};

<Header /> is a simple React.FC. TS gives an error saying:

Type '{ ref: RefObject; }' is not assignable to type 'IntrinsicAttributes & { children?: ReactNode; }'. Property 'ref' does not exist on type 'IntrinsicAttributes & { children?: ReactNode; }'

How can I overcome this issue?

Looks like you're trying to give a ref typed for an input element to another React component. If you are trying to forward the ref to an element inside the Header component, you can use React's forwardRef function.
