    if (!isAuth) {
      replace({
        pathname: '/login',
        state: {
          nextPathname: nextState.location.pathname,
        },
      })
    }
  }

  return (
    <Route path="/" component={App}>
      <Route path="/login" component={LoginWidgetContainer} />
      <Route path="/register" component={RegisterWidgetContainer} />
      <Route path="/public" component={Public} />
      <Route onEnter={reqAuth}>
        <Route path="/private" component={Private} />
      </Route>
    </Route>
  );
}

I'll edit this later to have transition/redirect backs
Another plan I had was to optionally raise a login modal too.

When I grok all this better, I'll post a boilerplate, with a client-only branch and a universal branch
