결국 필요없게 되었지만 블로그 포스트 TOC 만들면서 forwardedRef의 current값을 사용하고 싶어서 찾아본 내용.

// useForwardRef hook
import { ForwardedRef, useEffect, useRef } from "react";
export const useForwardRef = <T>(
ref: ForwardedRef<T>,
initialValue: any = null
) => {
const targetRef = useRef<T>(initialValue);
useEffect(() => {
if (!ref) return;
if (typeof ref === "function") {
ref(targetRef.current);
} else {
ref.current = targetRef.current;
}
}, [ref]);
return targetRef;
};
// TOC
export const TOC = forwardRef<HTMLDivElement, TOCProps>({ content }, ref) => {
const forwardedRef = useForwardRef<HTMLDivElement>(ref)
// forwardRef로 전달받은 ref의 current값 접근 및 사용 가능
console.log(forwardedRef.current);
...
}
