Next.js: web's default framework in 2026

Next.js with React Server Components clarified the 'frontend vs. backend' split inside React. Components render either on the server (DB access, sensitive API keys) or on the client (interaction). The split fundamentally solves performance and security.

App Router (file-based routing + layouts + parallel routes) is cleaner than the old Pages Router. We start every new project on App Router.

Server Actions make writing directly from forms to the database simple. No backend API endpoint required — define a server function as the form action. A serious code reduction in small/mid projects.

Large projects still get a separate API layer; Server Actions still speed up form-heavy CRUD screens significantly.

Incremental Static Regeneration serves dynamic-but-rarely-changing content (marketing pages, blog) like static. Foundation of the Lighthouse Performance >= 95 target.

Cache strategy is route-based: ISR for marketing, SSR + cache: 'no-store' for user-specific data, static for static content. The combination delivers both speed and accuracy.

Vercel is Next.js's 'native' platform — fastest, easiest deploy. We use Vercel in most projects. For enterprise self-host needs, Docker (output: standalone) is ready.

We use Edge Runtime in special cases: globally low-latency APIs, A/B test middleware. Node runtime is enough for most cases.
