Are you looking to enhance the user experience in your React application by implementing smooth auto-scrolling functionality? Look no further! In this blog post, we'll guide you through how to create a custom React hook that automatically scrolls to the bottom of a container when new content is added. Let's dive in!

Implementing Auto-Scroll Hook
We'll start by creating a custom React hook named useAutoScroll.tsx that handles the auto-scrolling functionality. This hook will utilize the useEffect hook to trigger the scroll action whenever new content is added to the container.

import { useEffect } from "react";

function useScrollToBottom(element: HTMLDivElement | null, data: any) {
  const scrollToBottom = () => {
    if (element) {
      element.scrollIntoView({ behavior: "smooth" });
    }
  };

  useEffect(() => {
    scrollToBottom();
    // eslint-disable-next-line react-hooks/exhaustive-deps
  }, [data]);
}

export default useAutoScroll;

Using the Auto-Scroll Hook
Next, let's see how you can use the useAutoScroll hook in your component.

In your component file (demoFile.tsx), you can use the useAutoScroll hook by passing a reference to the target element and the dependency that triggers the scroll.

const scrollRef = useRef<HTMLDivElement | null>(null);
useAutoScroll(scrollRef.current, dependency);

// Ensure that this <div> is added after the scrolling content
return (
  <div ref={scrollRef} />
);

By following these steps and incorporating the useAutoScroll hook into your React components, you can achieve a seamless auto-scrolling experience for your users as new content is dynamically loaded.

Enhance your React application with this auto-scrolling functionality to keep your users engaged and provide a smooth browsing experience. Happy coding! 🚀
