This flexibility allows you to tailor event handling to your specific needs, enhancing the reusability of your code.

By encapsulating the repetitive useEffect pattern, useEffectOnce allows you to focus on the logic within the effect function itself. This elegant solution saves you from writing boilerplate code repeatedly and helps keep your component files clean and concise.

One of the key advantages of useDeepCompareEffect is its ability to prevent unnecessary re-renders. By performing a deep comparison between the current and previous dependencies, the hook intelligently determines if the effect should be triggered, leading to optimized performance in scenarios where shallow comparisons fall short.

One of the main advantages of useDebugInformation is its simplicity. By integrating just a few lines of code into your component, you gain access to a wealth of debugging data. The hook tracks the number of renders, changed props, time since the last render, and the timestamp of the last render. This comprehensive information empowers you to analyz…

One of the main advantages of useDebounce is its simplicity and flexibility. By wrapping your callback function, delay duration, and any dependencies in this custom hook, you can effortlessly implement debouncing functionality without cluttering your component code. The hook takes care of managing the timeout and clears it when necessary, ensuring…

Copying text to the clipboard in a React application can be a tedious task. To simplify this process, I've created a powerful custom hook called useCopyToClipboard. With just a few lines of code, this hook streamlines the copy-to-clipboard functionality, providing developers with a hassle-free solution.

One of the key advantages of this custom hook is the ability to update the cookie value. The updateCookie function, returned by useCookie, enables you to modify the value of the cookie. By invoking this function with a new value and optional options, such as expiration or path, you can instantly update the cookie. Additionally, the hook convenientl…

One of the main advantages of useClickOutside is its ease of use. Simply import the hook into your component and pass the desired component's reference and a callback function. The hook takes care of the event listener setup and cleanup, saving you time and effort. Plus, it works seamlessly with functional components using the useState and useRef h…

The useAsync hook takes in a callback function that performs the asynchronous operation and an optional array of dependencies. It returns an object with three properties: loading, error, and value. The loading property indicates whether the operation is currently in progress, while the error property holds any error messages encountered during the…
