React Router Scroll To Top On Every Transition

One common struggle that developers encounter when building web applications with React Router is managing the scroll position during navigation transitions. Have you ever noticed how, when navigating through a website, the scroll position does not reset automatically and ends up in strange places like halfway down a page or even at the bottom?

The good news is that React Router provides a straightforward solution to this problem by allowing you to automatically scroll to the top of the page on every route transition. In this article, we will guide you through the process of implementing this feature in your React application.

First, let's install the necessary packages. If you haven't already installed React Router in your project, you can do so by running the following command:

Bash

npm install react-router-dom

Next, we need to create a custom scroll-to-top component that will handle the scrolling behavior for us. Below is an example of how you can define this component:

Jsx

import { useEffect } from 'react';
import { withRouter } from 'react-router-dom';

const ScrollToTop = ({ history }) =&gt; {
  useEffect(() =&gt; {
    const scrollToTop = () =&gt; {
      window.scrollTo(0, 0);
    };

    const unlisten = history.listen(scrollToTop);
    return () =&gt; {
      unlisten();
    };
  }, [history]);

  return null;
};

export default withRouter(ScrollToTop);

In the code snippet above, we are using the `useEffect` hook to set up a listener that scrolls the window to the top whenever a route change occurs. We are also using the `withRouter` higher-order component from `react-router-dom` to ensure that our `ScrollToTop` component has access to the `history` object.

Now that we have our `ScrollToTop` component ready, we need to include it in our application to enable the scroll-to-top behavior. You can achieve this by simply rendering the `ScrollToTop` component at the top level of your application like this:

Jsx

import React from 'react';
import { BrowserRouter as Router } from 'react-router-dom';
import ScrollToTop from './ScrollToTop';

const App = () =&gt; (
  
    
    {/* Your other routes and components */}
  
);

export default App;

By placing the `ScrollToTop` component inside the `Router`, we ensure that it will be mounted for every route change and will handle the scrolling behavior accordingly.

In conclusion, with a few simple steps, you can implement a scroll-to-top feature in your React application using React Router. This functionality enhances user experience by ensuring that the page scrolls to the top on each route transition, providing a seamless browsing experience. Incorporating small details like this can make a significant difference in the overall usability and polish of your web application. So, give it a try and see the positive impact it can have on your users' journey through your site.
