nextjs-16-architecture

Feature-based architecture organizes Next.js 16 projects into features/{feature}/ folders with dedicated layers for data fetching, server actions, and UI components. This separation enables scalable applications with clear boundaries between server and client logic, consistent file naming (one file per concept), and explicit cache invalidation workflows using 'use cache' and cacheTag directives.

Cache-first patterns in Next.js 16 use 'use cache' declarations, cacheTag, and cacheLife to control revalidation boundaries. Implement get-{entity}.ts files in a data layer, connect them to server actions with explicit cache invalidation, and pair with Suspense components and skeletons to render cached data while background updates occur.

Server components handle data fetching, cache management, and sensitive operations; client components manage interactivity and state. Next.js 16 architecture guidance clarifies this boundary: use server actions to bridge them, apply 'use cache' at the server boundary, and structure layouts and app routes to enforce this separation systematically across feature folders.

Yes. Next.js 16 server actions integrate directly with cache invalidation via cacheTag and explicit revalidation workflows. Define cache tags in your get-{entity}.ts data layer, then call invalidation from server actions to trigger revalidation. This ensures mutations update cached data consistently across your feature-based architecture.

Absolute imports are recommended as a convention within Next.js 16 feature-based architecture to simplify navigation across features/{feature}/ layers and maintain clarity as projects scale. Combined with one-file-per-concept naming and Suspense-driven rendering, they support consistent file discovery and reduce import path fragmentation.

Next.js 16 app routes, layouts, and i18n follow standardized patterns within feature-based organization. Use app/ routing with Suspense boundaries at layout levels, implement skeletons for streamed content, and pair with server-side caching via 'use cache' to deliver performance-optimized, internationalized routes without blocking initial page render.
