How to Create a Scroll To Top Button in React

Last updated on June 29, 2021 A Goodman Loading... Post a comment

For long web pages with a lot of content, a back-to-top button will be very useful. This button will make it easy and convenient for the user to return to the top of the page once they have scrolled down some distance.

In this article, we are going to create a back-to-top button from scratch without using any third party libraries. What used in the example below are useState hook, useEffect hook, and the window object that is supported by all browsers that support Javascript.

The Example


It doesn’t make lots of sense if the back-to-top button appears even when the user was at the top of the page. It should only show up when the user has scrolled down to a little bit.

A short screen capture is worth more than a thousand words:

The Code

1. Create a new React app and replace all of the default code in src/App.js by the following:

// App.js
import { useEffect, useState } from "react";
import "./App.css";

const App = () => {
  // The back-to-top button is hidden at the beginning
  const [showButton, setShowButton] = useState(false);

  useEffect(() => {
    window.addEventListener("scroll", () => {
      if (window.pageYOffset > 300) {
      } else {
  }, []);

  // This function will scroll the window to the top 
  const scrollToTop = () => {
    window.scrollTo(0, 0);

  return (
      <div className="container">
        <div className="box box--1"></div>
        <div className="box box--2"></div>
        <div className="box box--3"></div>
        <div className="box box--4"></div>
        <div className="box box--5"></div>

      {showButton && (
        <button onClick={scrollToTop} className="back-to-top">
      {/* &#8679; is used to create the upward arrow */}

export default App;

2. Remove all of the unwanted code in App.css then add this:

.container {
  width: 500px;
  margin: auto;
  text-align: center;

.back-to-top {
  position: fixed;
  bottom: 20px;
  right: 20px;
  font-size: 100px;
  background: orange;
  color: white;
  cursor: pointer;
  border-radius: 100px;
  border: none;
  box-shadow: 0 5px 10px #ccc;

.back-to-top:hover {
  background: red;

/* Just some color boxes to make the page longer */
.box {
  width: 100%;
  height: 80vh;
  margin: 30px 0;

.box--1 {
  background: yellow;

.box--2 {
  background: green;

.box--3 {
  background: pink;

.box--4 {
  background: grey;

.box--5 {
  background: purple;

3. Run your project and check the result.


We’ve made a back-to-top button without using any third-party packages. From here, you can easily implement this useful button in other projects as needed. If you’d like to learn more new and interest things about modern React, take a look at the following articles:
