How to emulate window.location with react-router and ES6 classes

After wasting time with react router, I finally switch to basic javascript.

1. Create a component for your redirect:

   Route path=”*” component={NotFound}

2. In the component use window.location to redirect:

    componentDidMount() {
         if (typeof window !== 'undefined') {
              window.location.href = "http://foo.com/error.php";
         }
    }
