1-124: Summary: Changes align with PR objectives, but comprehensive testing is crucial.The modifications to the App component, including the removal of Redux-related logic and the token refresh mechanism, align well with the PR objectives of fixing the race condition in the Axios interceptor for refresh token. These changes should help prevent unauthorized requests due to expired tokens.
However, to ensure the overall functionality and security of the application, please consider the following:
- Thoroughly test the new token refresh implementation to verify its effectiveness and reliability.
- Conduct end-to-end testing of the authentication flow to ensure seamless user experience.
- Verify that all parts of the application that relied on the previous Redux-based token refresh mechanism have been updated accordingly.
- Review and update any relevant documentation to reflect these architectural changes.
Consider documenting the new token refresh mechanism and updating any relevant architecture diagrams to reflect these changes. This will help maintain clear communication about the application's authentication flow for future development and maintenance.

10-10: LGTM: Import changes align with PR objectives.The removal of the
useDispatchimport is consistent with the PR's goal of removing the Redux-based token refresh logic from the App component.

86-92: Verify 401 error handling in queryClient setup.The error handling logic in the queryClient setup has been retained, which is good for maintaining the application's robustness. However, given the changes to the token refresh mechanism, it's important to verify if the current 401 error handling is still appropriate.
Please review the 401 error handling logic to ensure it aligns with the new token refresh implementation.
To assist in verifying the 401 error handling, please run the following script:
#!/bin/bash # Description: Search for 401 error handling implementations echo "Searching for 401 error handling logic:" rg --type typescript --type javascript '(401|unauthorized)' -g '!{test,spec,__tests__}/**' echo "\nSearching for refresh token logic:" rg --type typescript --type javascript '(refresh.*token|token.*refresh)' -g '!{test,spec,__tests__}/**'This script will help identify where 401 error handling and refresh token logic are implemented throughout the application. Please review the results to ensure that 401 errors are handled appropriately in conjunction with the new token refresh mechanism.

52-124: Approve removal of Redux logic, but verify new token refresh implementation.The removal of Redux-related logic and the useEffect hook for token refresh from the App component aligns with the PR objectives. This change addresses the potential race condition where Axios calls could be made before the interceptor was fully configured.
However, it's crucial to ensure that the token refresh functionality has been implemented elsewhere in the application to maintain proper authentication flow.
To verify the new token refresh implementation, please run the following script:
This script will help identify where the new token refresh logic might have been implemented. Please review the results to ensure that the token refresh functionality is properly handled in the application.
Verification successful
Verified removal of Redux logic and confirmed token refresh implementation exists elsewhere.

52-52: Logic for enabling the query is appropriate.The
enabledconditionBoolean(axiosInterceptorAdded && authStore.accessToken)ensures the query runs only when the interceptor is set up and an access token is available, preventing unauthorized requests.

12-12: LGTM! Consider adding a comment for clarity.The addition of
isPendingto the destructured object fromuseGetUserQueryis a good improvement. It provides a more granular representation of the query status, which can help address the race condition mentioned in the PR objectives.Consider adding a brief comment explaining the difference between
isPendingandisLoadingfor future maintainers:// isPending: true when the query is initialized but hasn't started loading // isLoading: true when the query is actively fetching data const { data: user, isSuccess, isLoading, isPending } = useGetUserQuery();

1-24: Overall, great job addressing the race condition!The changes made to this file effectively tackle the race condition issue described in the PR objectives. The addition of
isPendingand its incorporation into the loading state logic should prevent premature API calls and ensure that the Axios interceptor is properly set up before any requests are made.As a minor suggestion for future improvements, consider adding error handling to the
useGetUserQueryhook:const { data: user, isSuccess, isLoading, isPending, error } = useGetUserQuery(); // ... existing code ... return ( <AuthContext.Provider value={{ isLoggedIn: isSuccess, isLoading: isPending || isLoading, error: error ? error.message : null }}> {/* ... existing code ... */} </AuthContext.Provider> );This addition would allow consumers of the
AuthContextto handle potential errors in the user query, improving the overall robustness of the authentication system.

What this PR does / why we need it:
This PR addresses a race condition in the implementation of the Axios interceptor for refreshing access tokens. Recently, a refresh token mechanism was introduced, which can issue new access tokens via the Axios interceptor. However, the interceptor logic resides within a
useEffecthook, leading to scenarios where Axios calls may be triggered before the interceptor is fully set up. This can result in unauthorized requests being sent with expired tokens.To resolve this issue, the Axios interceptor will be configured before any calls are made, ensuring that all requests utilize a fresh access token.
