41-70: Consider refining error handling and state managementWhile the changes effectively address the loading issue, here are some suggestions to further improve the code:
The use of both React Query and Redux for state management could potentially lead to synchronization issues. Consider consolidating state management to one system if possible.
The error handling in the
useEffecthook that watches the query state is quite broad. It might be beneficial to handle different types of errors differently. For example:useEffect(() => { if (query.isSuccess) { dispatch(setUserData(query.data as User)); } else if (query.isError) { if (axios.isAxiosError(query.error) && query.error.response?.status === 401) { // Handle unauthorized error dispatch(logout()); dispatch(setUserData(null)); axios.defaults.headers.common["Authorization"] = ""; } else { // Handle other types of errors console.error("An error occurred while fetching user data:", query.error); } } }, [dispatch, query.data, query.isError, query.isSuccess, query.error]);
- There's no explicit handling of a scenario where the access token is present but invalid (apart from the 401 handling in the axios interceptor). Consider adding a mechanism to validate the token's expiration on the client-side to potentially reduce unnecessary API calls.
Could you provide more information on the error handling strategy, particularly for scenarios not covered by the current implementation?

19-19: SimplifiedAuthContext.Providervalue addresses loading issueThe
AuthContext.Providernow directly usesisLoadinginstead of the previously combinedisAuthLoading. This change simplifies the context value and should resolve the issue of the page hanging indefinitely when the Access Token is missing.To ensure this change fully addresses the loading issue mentioned in the PR objectives, let's verify the usage of
isLoadingin components that consume theAuthContext:#!/bin/bash # Description: Check usage of `isLoading` from AuthContext in other components rg --type typescript --type tsx 'const.*\{.*isLoading.*\}.*=.*useContext\(AuthContext\)'This will help us confirm that the loading state is being correctly utilized in child components.
12-12: Removal ofisPendingsimplifies loading state managementThe removal of
isPendingfrom the destructured return value ofuseGetUserQueryaligns with the PR objective of fixing the loading behavior. This change simplifies the state management by relying solely onisLoading.To ensure this change doesn't introduce any issues, let's verify the usage of
isPendingin other parts of the codebase:If the script returns no results, it confirms that
isPendingis not used elsewhere, supporting this change.✅ Verification successful

12-19: Verify overall impact on loading behavior across the applicationThe changes made to simplify the loading state management appear to address the issue of the page crashing when the Access Token is absent. However, to ensure the robustness of this solution, consider the following:
- Test the application thoroughly with various scenarios of Access Token presence/absence.
- Verify that all components consuming the
AuthContexthandle the loading state correctly.- Ensure that there are no race conditions between the loading state and the user data fetching.
To help with this verification, you can run the following script to identify all components that might be affected by this change:

70-70: Excellent fix for the loading behavior!This change effectively addresses the issue of incorrect loading state when the Access Token is absent. By including
!axiosInterceptorAddedin theisLoadingcondition, you ensure that the app remains in a loading state until the axios interceptor is properly set up. This prevents premature rendering that could lead to crashes or incorrect behavior.The spread operator
...querymaintains all existing properties of the query object, while the customisLoadingproperty provides a more accurate representation of the loading state. This approach elegantly solves the problem described in the PR objectives without introducing breaking changes.
What this PR does / why we need it:
This PR addresses an issue where the page would crash when there is no Access Token. Specifically, it modifies the loading conditions in the Auth Provider to ensure that the loading state behaves correctly when an Access Token is not present.
Previously, when the Access Token was missing, the loading state would remain true indefinitely, causing the application to hang without properly redirecting the user.
