How to handle 401 unauthorized error in a Redux React application

In response to a client request, the server may return a 401 Unauthorized error. You must correctly catch it, for example, clear the state and redirect to the authorization page. To solve this problem, we wrote a custom Middleware which, in our opinion, is the best solution.


import * as actions from 'actions';



const authInterceptor = ({ dispatch }) => (next) => (action) => {

  if (action.status === 401) {

    dispatch(actions.removeJwt());

  } else {

    next(action);

  }

};
