disable back button in react-router 2

Your best bet, is when the user is login he/ she is redirected to dashbaord. if for some reason the user click on back button you should:

if the user is logged in stay on the page dashboard

if(logged) {
  history.pushState(null, null, location.href);
  window.onpopstate = function(event) {
    history.go(1);
  };
}

it will be not possible to go back.

Applying all these hacks the URL changes to login for a moment and then to wherever-we-push. Instead, what we can do is: In login, where api endpoint returns success, do:

history.replace('/Whatever_screen')

This will remove login screen from window.history stack, and the screen will not flicker.
