Next.js Rendering & App Router Architecture
Static generation, server rendering, client rendering and streaming server components each solve a different problem, and mixing them up is the single most common cause of slow, unrankable Next.js applications. We choose the rendering mode per route and document why, so the decision survives the person who made it moving on.
- App Router work: server components, streaming, and a deliberate static/server/client split per route
- Incremental static regeneration for content that changes but doesn't need a full rebuild
- Migration of stalled Pages Router applications onto the App Router, one route at a time
- Core Web Vitals tracked from real users, not a single lab score
