Prefetching queries in React Query loads data in advance before users navigate to a page or trigger an action, creating a seamless experience with instant data display. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented prefetching strategies in data-heavy admin dashboards throughout my 11 years of React development. The most effective approach is using queryClient.prefetchQuery in event handlers or navigation logic to load data proactively. This method populates the cache before components mount, eliminating loading states for better user experience.

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.

React Query simplifies server state management by handling caching, synchronization, and background updates automatically, eliminating the need for manual data fetching logic. As the creator of CoreUI, a widely used open-source UI library, I’ve integrated React Query in complex data-driven applications throughout my 11 years of React development. The most effective approach is wrapping your app with QueryClientProvider and using the useQuery hook for data fetching. This method provides automatic caching, background refetching, and loading states out of the box.

SWR (Stale-While-Revalidate) is a powerful data fetching library that provides automatic caching, revalidation, and error handling out of the box. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented SWR in production React applications throughout my 11 years of development experience. The most straightforward approach is using the useSWR hook with a fetcher function for automatic data management. This method handles caching, background updates, and loading states automatically without manual state management.

Caching API data prevents redundant network requests, improves application performance, and provides better user experience during navigation. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented data caching strategies in React applications throughout my 11 years of framework development. The most effective approach is creating a custom hook that stores responses in memory using a Map or localStorage for persistent caching. This method provides automatic cache management with minimal code changes in your components.

Skeleton loaders provide better user experience than spinners by showing content placeholders that match the layout of actual data. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented skeleton screens in enterprise applications throughout my 11 years of React development. The most straightforward approach is creating reusable skeleton components with CSS animations that mimic your content structure. This method improves perceived performance and reduces layout shift when data loads.

Fetching paginated data from APIs is essential for handling large datasets efficiently without overwhelming the client or server. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented pagination in countless data-driven applications over my 11 years of React development. The most effective approach is using state to track the current page and useEffect to fetch data whenever the page changes. This method provides smooth pagination with proper loading states and error handling.

Rendering large lists with thousands of items can severely impact performance and cause lag in React applications. As the creator of CoreUI, a widely used open-source UI library, I’ve optimized list rendering for enterprise applications throughout my 11 years of React development. The most effective solution is using virtualization libraries like react-window, which render only the visible items in the viewport. This approach dramatically improves performance by minimizing DOM nodes and reducing memory consumption.

Downloading files programmatically is a common requirement in modern web applications, from exporting reports to downloading generated content. As the creator of CoreUI, a widely used open-source UI library with extensive React support, I’ve implemented file download functionality countless times over my 11 years of React development. The most reliable approach is creating a temporary object URL from a Blob and triggering a download via a programmatic anchor click. This method works consistently across all modern browsers and gives you full control over the download process.

Displaying loading spinners provides visual feedback during async operations, improving perceived performance in React applications. As the creator of CoreUI with over 11 years of React development experience since 2014, I’ve implemented loading states in countless data-fetching scenarios. The most effective solution is to use state to track loading status and conditionally render spinner components. This approach provides clear feedback and improves user experience during data loading.
