Query invalidation in React Query forces refetching of stale data after mutations, ensuring the UI stays synchronized with server state without manual cache updates. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented query invalidation patterns in admin dashboards throughout my 11 years of React development. The most reliable approach is using queryClient.invalidateQueries in mutation callbacks to automatically refetch affected data. This method maintains data consistency across components without complex state synchronization logic.

Using Vue with GraphQL provides powerful data fetching capabilities through declarative queries, efficient caching, and real-time subscriptions for modern application development. As the creator of CoreUI with extensive Vue experience since 2014, I’ve implemented GraphQL integrations in numerous enterprise applications for optimized data management and user experiences. The most effective approach involves using GraphQL clients with Vue 3 Composition API to handle queries, mutations, and subscriptions with reactive data management. This method provides type-safe API interactions while maintaining excellent performance through intelligent caching and optimistic updates.

Vuex mutations are the only way to change store state in Vue applications, providing predictable state updates with proper debugging and time-travel capabilities. As the creator of CoreUI with over 25 years of development experience, I use mutations extensively for reliable state management across enterprise applications. The most effective approach is defining mutations as synchronous functions that receive state and payload parameters for direct state modification. This ensures traceable, debuggable state changes that work seamlessly with Vue DevTools and maintain application predictability.
