Autogenerate IDs to facilitate WAI-ARIA and server rendering.

A string can be supplied as an argument to be useId in lieu of the auto-generated ID. This is handy for accepting user-provided prop IDs that need to be deterministic.

import { useId } from "@reach/auto-id";

function FormField(props) {
	const id = useId(props.id);
	return (
		<React.Fragment>
			<label htmlFor={id}>{props.label}</label>
			<input type={props.type} name={props.name} id={id} />
		</React.Fragment>
	);
}
