Custom Scroll Position Hook

Snippet Overview

This snippet provides a custom React hook, useScrollPosition, to monitor the scroll position of the window. It's useful for creating dynamic UI adjustments based on the user's scroll behavior.

Snippet Explanation

The useScrollPosition hook utilizes React's useState and useEffect to update the scroll position on window scroll events. This allows for responsive and interactive UI elements that adapt to the user's scrolling actions.

Code

import { useEffect, useState } from 'react';

export const useScrollPosition = () => {
  const [scrollPosition, setScrollPosition] = useState(0);

  useEffect(() => {
    const updatePosition = () => {
      setScrollPosition(window.pageYOffset);
    };

    window.addEventListener('scroll', updatePosition);
    updatePosition();

    return () => window.removeEventListener('scroll', updatePosition);
  }, []);

  return scrollPosition;
};

Usage

• Import and use the useScrollPosition hook within your React components.
• Access the scrollPosition value returned by the hook to make dynamic UI changes based on scroll behavior.
• Features

Reusability: Easily reuse the hook across multiple components or projects.

• Efficiency: Proper cleanup of event listeners ensures optimal performance.
• Flexibility: Extend the hook's logic to handle more complex scroll-related tasks as needed.

Conclusion

The useScrollPosition hook provides a straightforward solution for responding to scroll events in React applications. It empowers developers to create engaging user experiences by adapting UI elements dynamically as users interact with the content.
