Finessed variant of ScrollToTop from react-router docs https://github.com/ReactTraining/react-router/blob/master/packages/react-router-dom/docs/guides/scroll-restoration.md#scroll-to-top

ScrollToTopHandler.jsx

import React, { Component } from 'react'
import { withRouter } from 'react-router'

const topCoordinates = [0, 0]

const { scrollTo } = window

class ScrollToTopHandler extends Component {
  // Arrow method, requires stage 2 Babel preset
  render = () => null

  componentDidUpdate (prevProps) {
    if (this.props.location === prevProps.location) {
      return
    }

    scrollTo(...topCoordinates)
  }
}

export default withRouter(ScrollToTopHandler)
