Invalidate login when API authentication expires?

I'm trying to log a user out, and send them to the login page, if our API responds to say the session is invalid. As an example, a login session is invalidated if someone logs in with the same account on a different browser/device. Our API will start responding with a 401. I can get the 401 via an axios interceptor. How can I kick the "check" login functionality at this point, to then handle the redirect to login?

Hey @johnwards! I'm the kapa.ai support bot. I've searched through the docs to try to answer your question. :wave:

---------------------- You can use the useLogout (https://refine.dev/docs/api-reference/core/hooks/auth/useLogout/) hook to call the logout method of the authProvider (https://refine.dev/docs/api-reference/core/providers/auth-provider/). This will log out the user and redirect them to the /login page by default. You can also provide a custom URL to the mutate function of the useLogout hook, which will override the one on the authProvider.

import { useLogout } from "@pankod/refine-core";  
  
const { mutate: logout } = useLogout<{ redirectPath: string }>();  
  
logout({ redirectPath: "/custom-url" });

import { useLogout } from "@pankod/refine-core";  
  
const { mutate: logout } = useLogout<{ redirectPath: string }>();  
  
logout({ redirectPath: "/custom-url" });

Then, you can handle this URL in your logout method of the authProvider.

  
const authProvider: AuthProvider = {  
 ...  
 logout: ({ redirectPath }) => {  
 ...  
 return Promise.resolve(redirectPath);  
 }  
}

  
const authProvider: AuthProvider = {  
 ...  
 logout: ({ redirectPath }) => {  
 ...  
 return Promise.resolve(redirectPath);  
 }  
}

You can also use an axios interceptor (https://github.com/axios/axios#interceptors) to detect a 401 response from the API and call the logout method.

import axios from "axios";  
  
const axiosInstance = axios.create();  
  
axiosInstance.interceptors.response.use(  
 (response) => response,  
 (error) => {  
 if (error.response.status === 401) {  
 logout({ redirectPath: "/custom-url" });  
 }  
 return Promise.reject(error);  
 }  
);

import axios from "axios";  
  
const axiosInstance = axios.create();  
  
axiosInstance.interceptors.response.use(  
 (response) => response,  
 (error) => {  
 if (error.response.status === 401) {  
 logout({ redirectPath: "/custom-url" });  
 }  
 return Promise.reject(error);  
 }  
);

useLogout data hook from refine is a modified version of react-query's useMutation for unauthentication.

@kapa.ai I don't think you can use useLogout in an axios interceptor. That looks to be breaking rules of hooks. Ah! Simply intercepting the error, deleting the local storage and then doing a window.location.reload(); will do nicely It's hacky, I'd rather redraw so I can pass a message. But it will do for now. Any bright ideas about how to do this without reloading very welcome

I think it is a good solution 👏🏻
