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.

Implementing infinite scroll provides a seamless browsing experience for React applications with large datasets by loading content automatically. As the creator of CoreUI with over 11 years of React development experience since 2014, I’ve built infinite scroll features in countless social feeds and product listings. The most effective solution is to use the Intersection Observer API to detect when users reach the bottom and load more data. This approach is performant, doesn’t require scroll event listeners, and provides smooth user experience.

Implementing drag and drop file upload provides an intuitive user experience for React applications handling file uploads. As the creator of CoreUI with over 11 years of React development experience since 2014, I’ve built drag and drop interfaces in countless file management systems. The most effective solution is to use HTML5 drag and drop events with state to manage drag status and uploaded files. This approach works natively in all modern browsers without external libraries.

Implementing filtering functionality allows users to narrow down data based on specific criteria, essential for data-heavy React applications. As the creator of CoreUI with over 11 years of React development experience since 2014, I’ve built advanced filtering systems in countless enterprise dashboards. The most effective solution is to use state to track filter criteria and the array filter method to apply multiple conditions. This approach provides flexible, real-time filtering with support for multiple filter combinations.

Implementing sorting functionality allows users to organize data in React lists by any column, essential for data tables and organized content. As the creator of CoreUI with over 11 years of React development experience since 2014, I’ve built sortable lists and tables in countless enterprise applications. The most effective solution is to track the sort field and direction in state and use the array sort method to reorder data. This approach provides flexible, client-side sorting with clear visual feedback.

Implementing search functionality is essential for React applications that display lists of data, improving user experience by helping users find items quickly. As the creator of CoreUI with over 11 years of React development experience since 2014, I’ve built search features in countless data tables and lists. The most effective solution is to use controlled input for the search query and filter the data array based on the search term. This approach is simple, performant, and provides instant search results as users type.
