# Merge-Refs

A function that merges React refs into one. Filters out invalid (eg. falsy) refs as well and returns original ref if only one valid ref was given.

## tl;dr

- Install by executing `npm install merge-refs` or `yarn add merge-refs`.
- Import by adding `import mergeRefs from 'merge-refs'`.
- Use it in `ref` like so: `<div ref={mergeRefs(ref, someOtherRef)} />`

## Accepted refs

- Refs created using `createRef()`
- Refs created using `useRef()`
- Functional refs

## Example

```tsx
function Hello() {
  const ref1 = useRef<HTMLDivElement>(); // I'm going to be updated!
  const ref2 = (element: HTMLDivElement) => {
    // I'm going to be called!
  };

  return <div ref={mergeRefs(ref1, ref2)} />;
}
```
