How do you optimize a Next.js App Router setup to combine dynamic Server-Side Rendering (SSR) with high edge caching performance?
To combine live data freshness with fast edge speeds, avoid marking entire routes as fully dynamic unless absolutely necessary. Use Next.js segment configuration options like revalidate = 3600 to cache page structures at the edge for fixed windows of time. For parts of the UI that require real-time updates (such as live post counts or user upvotes), wrap those specific items in standard React Suspense boundaries and fetch the data on the client side using libraries like SWR or React Query. This structure allows your main page HTML to load instantly from a global CDN while live data hydrates smoothly right after rendering.
