RTK Query provides utilities to reset or clear cached data programmatically. This is helpful when users log out, switch accounts, or when you need to force-refresh application state.
1.
api.util.resetApiState(): Clears all cached query data, mutations, and subscriptions for the entire API slice.2.
api.util.invalidateTags(): Invalidates specific cached data associated with provided tags, prompting them to refetch.3. Store Reset: You can also manually reset the Redux store if you want to clear all app state, including RTK Query cache.
In this example, when a user logs out, resetApiState() clears all cached queries and mutations, ensuring that sensitive or user-specific data is removed.
If your endpoints use tag-based caching, invalidating tags will automatically trigger refetches for related queries without clearing the entire cache.
- On User Logout: To clear all user-specific cached data.
- On Environment Change: When switching between tenants or servers.
- For Debugging or State Reset: To force a clean app state for troubleshooting.
Using resetApiState() or invalidateTags() gives you fine control over cache management, keeping your app’s data consistent and secure.
