Components: Forwarding Refs
Forwarding Refs
const FancyButton = React.forwardRef((props, ref) => (
<button ref={ref} className="FancyButton">
{props.children}
</button>
));
// You can now get a ref directly to the DOM button:
const ref = React.createRef();
<FancyButton ref={ref}>Click me!</FancyButton>;
Is an opt-in feature that lets some components take a ref they receive, and pass it further down (in other words, “forward” it) to a child.
