React Hook useEvent

Overview

This repository includes a custom React Hook useEvent which is used for handling and passing events. This hook receives a callback function as an argument and returns a memoized version of that callback.

The useEvent hook takes advantage of useRef and useCallback to maintain callback reference and prevent unnecessary re-renders, resulting in an improvement of performance.

Installation

npm i @khmilevoi/use-event

Then, copy the useEvent function to your project.

Usage

Here's an example of how to use the useEvent hook:

import { useEvent } from "@khmilevoi/use-event";

// Define your callback
const yourCallback = (arg1, arg2) => {
    // Your callback implementation
};

// Use the useEvent hook
const memoizedCallback = useEvent(yourCallback);

In this case, memoizedCallback is a memoized version of yourCallback that will only change if yourCallback does. This is useful when passing callbacks to optimized child components that rely on reference equality to prevent unnecessary renders (e.g., shouldComponentUpdate).

API

useEvent(callback)

Input

• callback: Function: The callback function to be memoized.

Output

• Returns a memoized version of the callback function that only changes if the callback does.

Note

Please note that this custom Hook is not officially a part of the React library. It's a utility function designed to help in certain use cases. Please use it responsibly and with understanding of its implications.
