It's kinda rare to find a smooth scrolling button that takes you to the top of the page on modern blogging websites, especially the ones that are a long 15 minute read!

However, whenever I come across one, I always tend to use it and appreciate the elegance of this simple button that has such a specific job.

After perusing Stack Overflow and GitHub for solution, I came across an elegant React component that uses Hooks and wanted to share it with this community!

Our button should function like this: Alt Text

These are following test-cases for our component:

  • Button should always be at the right bottom of the page
  • Button should be hidden and should only appear when we scroll for a certain height
  • On clicking it, we should be smoothly taken to the top of the page

The Hook component achieves the following functionality.

import React, { useEffect, useState } from "react";

export default function ScrollToTop() {
  const [isVisible, setIsVisible] = useState(false);

  // Top: 0 takes us all the way back to the top of the page
  // Behavior: smooth keeps it smooth!
  const scrollToTop = () => {
      top: 0,
      behavior: "smooth"

  useEffect(() => {
    // Button is displayed after scrolling for 500 pixels
    const toggleVisibility = () => {
      if (window.pageYOffset > 500) {
      } else {

    window.addEventListener("scroll", toggleVisibility);

    return () => window.removeEventListener("scroll", toggleVisibility);
  }, []);

//scroll-to-top classes: fixed, bottom:0, right:0
  return (
    <div className="scroll-to-top">
      {isVisible && (
        <div onClick={scrollToTop}>
          <h3>Go up!</h3>

We're almost done! Just import this component in your react file and stick it at the very end.

And voila, it should work!

Here is a basic, quick, and ugly demo of how it should function!
