My login application (react) and actual (react) application are in the same domain. My login application sets localStorage when user logs in successfully. In my actual application i have to check that value . if it is not there i have to redirect to login application in onload . What is the best practice to do that

                    In that case you cannot use Router, you need to use window.location – Shubham Khatri May 08 '18 at 07:50

        You can check it in the componentDidMount life cycle method as below.
class LoggedInComponent extends Component {
  componentDidMount() {
    if (!localStorage.get('loggedIn')) {
      window.location = "/login";
      // You mentioned login app and actual app is deferent.
      // So you should use window.location
      // Otherwise you can use react-router's router.push('/login') function.
    }
  }
}
Use componentDidMount only. Because react v17 is going to deprecate the componentWillMount function.

                    No you cannot do it with the router if both applications are different. – Akhil P May 08 '18 at 07:40
