About merge-refs
The npm package "merge-refs" serves a crucial role for developers working with React, a popular JavaScript library for building user interfaces. This module specifically addresses the challenge of managing multiple refs efficiently. Refs in React are used to get direct access to a DOM element or a component instance, but handling multiple refs traditionally requires setting up multiple references and manually managing them. "Merge-refs" simplifies this by merging multiple refs into a single ref callback that can be attached to React elements. This is particularly beneficial in complex components where multiple refs are needed, enhancing code maintainability and readability.
Using "npm install merge-refs" allows developers to easily integrate this functionality into their React projects. Once installed, "merge-refs" can drastically reduce the complexity of handling multiple refs, making the code cleaner and more efficient. It ensures that all assigned refs are called correctly, preserving the immutability and functionality of existing refs. This package is not only lightweight but also has minimal dependencies, making it an excellent choice for projects concerned with bundle size and performance. Additionally, its compatibility with the latest React versions ensures it is a future-proof choice for modern web development.
The "merge-refs" package is also backed by a strong community and comprehensive documentation, which facilitates easy implementation and troubleshooting. It has been widely adopted, as indicated by its download numbers, and receives regular updates to stay aligned with new React features and improvements. This reliability and community support make "merge-refs" a trusted tool for developers looking to streamline their React applications' ref management.

import mergeRefs from 'merge-refs'. - Use it in
reflike so:<div ref={mergeRefs(ref, someOtherRef)} />
Accepted refs
- Refs created using
createRef() - Refs created using

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