React utility to merge refs 🖇

npm install react-merge-refs

Example

import React from "react";
import mergeRefs from "react-merge-refs";

const Example = React.forwardRef(function Example(props, ref) {
  const localRef = React.useRef();
  return <div ref={mergeRefs([localRef, ref])} />;
});

Why?

When developing low level UI components, it is common to have to use a local ref but also support an external one using React.forwardRef. Natively, React does not offer a way to set two refs inside the ref property. This is the goal of this small utility.

Today a ref can be a function or an object, tomorrow it could be another thing, who knows. This utility handles compatibility for you.
