Clear the react query cache

Hello, I want to clear the react query cache after signing out from the application. I tried to create query client instance and configured it in the options in <Refine/> after wrapping it with <QueryClientProvider /> and used the useQueryClient to clear the cache on signout but it didn't work at all. So how do we clear the react query cache in refine??

Hi @rawad_94037. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- In Refine, you can use the useLogout hook to handle the logout flow and clear the React Query cache. Here's how you can do it: First, import the useLogout and useQueryClient hooks from Refine:

import { useLogout } from "@refinedev/core";
import { useQueryClient } from "react-query";

import { useLogout } from "@refinedev/core";
import { useQueryClient } from "react-query";

Then, in your custom logout component, you can call the logout function from useLogout and the clear function from useQueryClient:

export const LogoutButton = () => {
  const { mutate: logout } = useLogout();
  const queryClient = useQueryClient();

  const handleLogout = () => {
    logout();
    queryClient.clear();
  };

  return <button onClick={handleLogout}>Logout</button>;
};

export const LogoutButton = () => {
  const { mutate: logout } = useLogout();
  const queryClient = useQueryClient();

  const handleLogout = () => {
    logout();
    queryClient.clear();
  };

  return <button onClick={handleLogout}>Logout</button>;
};

In this example, when the Logout button is clicked, the handleLogout function is called. This function first calls the logout function to log the user out, then calls queryClient.clear() to clear the React Query cache. For more information, you can refer to the useLogout documentation (https://refine.dev/docs/authentication/hooks/use-logout#usage) and the React Query documentation (https://react-query.tanstack.com/reference/QueryClient#queryclient). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

it's already implemented like so, I'm checking to see what is the right way to do it with refine

Hey @rawad_94037 make sure you are clearing the cache before redirection.

I tried it inside the application to avoid redirection but nothing is happening, cache is not cleared at all
