For React Router V4. React component to keep the scroll of the page and to restore it if the user clicks on the previous button of its browser
npm install react-router-scroll-memory
You have solution in this page https://reacttraining.com/react-router/web/guides/scroll-restoration for just scrolling to top on navigation on every transition. But if you click on the previous button, the page is also at the top even if you had scrolled on the page.
I did this package because I was frustrated that the new react router (4) does not restore the scroll when I click on the back button of my browser. By default, the component execute window.scrollTo(0,0), if the url not exist in memory.
only work with react and react router v4 and v5
