Learing NextJs useSession from NextAuth.js is a React hook that helps manage user authentication in a Next.js app. It provides session information, including whether a user is authenticated, their details, and the loading state. This makes it easy to control access to protected pages, redirect unauthenticated users, or display user-specific content dynamically. useSWR (Stale-While-Revalidate) is a data-fetching library that improves performance by caching API responses and automatically revalidating data in the background. It reduces unnecessary API calls, ensures users see the latest data without refreshing, and provides built-in error handling. By using mutate(), SWR allows instant UI updates when data changes, making it perfect for real-time applications.
