Scroll restore to top on navigation change

I am having a problem with scrolling, when navigating using react-router.

When I am navigating to a different component it is keeping the scroll position from the last navigation. However I want it to restore and start from the top whenever the navigation is changed.

 class App extends Component{
  render() {
   return(
    <BrowserRouter onUpdate={() => window.scrollTo(0, 0)} history={createBrowserHistory()}>
      <div style={{display: 'flex'}}>
        <div className='navBar'>
          <ul style={{listStyleType: 'none'}}>
            <li><Link to='/'>Home</Link></li>
            <li><Link to='/towns'>Towns</Link></li>
            <li><Link to='/pubs'>Pubs</Link></li>
            <li><Link to='/venues'>Venues</Link></li>
            <li><Link to='/cinemas'>Cinemas</Link></li>

          </ul>
        </div>

        <div style={{flex:1, padding:'0px'}}>
          {routes.map((route) => (
            <Route
              key={route.path}
              path={route.path}
              exact={route.exact}
              component={route.main}
              />
            ))}
          </div>
        </div>
      </BrowserRouter>
     )
   }
 }

However it doesn't work. I have a feeling the issue is with my style of navigation rather then the window.scrollTo() snippet.

To my knowledge, since react-router v4, BrowserRouter doesn't have an onUpdate function.

Several ways to accomplish it. This will be the easiest...

components/ScrollIntoView.js

import { PureComponent } from "react";
import { withRouter } from "react-router-dom";

class ScrollIntoView extends PureComponent {
  componentDidMount = () => window.scrollTo(0, 0);

  componentDidUpdate = prevProps => {
    if (this.props.location.pathname !== prevProps.location.pathname) window.scrollTo(0, 0);
  };

  render = () => this.props.children;
}

export default withRouter(ScrollIntoView);

routes/index.js

import React from "react";
import { BrowserRouter, Route, Switch } from "react-router-dom";
import Links from "../components/Links";
import Home from "../components/Home";
import About from "../components/About";
import Contact from "../components/Contact";
import ScrollIntoView from "../components/ScrollIntoView";

export default () => (
  <BrowserRouter>
    <div>
      <ScrollIntoView>
        <Links />
        <Switch>
          <Route exact path="/" component={Home} />
          <Route path="/about" component={About} />
          <Route path="/contact" component={Contact} />
        </Switch>
        <Links />
      </ScrollIntoView>
    </div>
  </BrowserRouter>
);

Or you can find another approach here: Scroll to the top of the page after render in react.js

My solution using React hooks

import { useEffect, useRef } from 'react';
import { withRouter } from 'react-router-dom';
import PropTypes from 'prop-types';

const ScrollIntoView = ({ children, location }) => {
  const prevLocation = useRef();

  useEffect(() => {
    if (prevLocation.current !== location.pathname) {
      window.scrollTo(0, 0);
      prevLocation.current = location.pathname;
    }
  }, [location]);

  return children;
};

ScrollIntoView.propTypes = {
  children: PropTypes.node,
  location: PropTypes.object
};

export default withRouter(ScrollIntoView);
