Case details
This speech introduces a powerful client-side caching strategy: Stale-While-Revalidate (SWR). Faith Adekunle will demonstrate how SWR enhances the performance and responsiveness of React applications. By leveraging SWR, clients can access a cached version of resources even if they are technically expired, while concurrently revalidating them with the origin server in the background. This proactive approach ensures a smooth and uninterrupted user experience, even in the face of network fluctuations or server delays. Furthermore, Faith will compare SWR to the widely-used useEffect hook for data fetching. While useEffect typically triggers after the component renders, the useSWR hook, provided by the SWR library, initiates data loading during the component rendering process. This speech will provide valuable insights into optimizing data fetching in React applications and empower developers to build high-performance, user-centric web experiences.
