Next.js 14 represents a major leap forward in React development. With the stable App Router, React Server Components, and enhanced performance features, Next.js has become the framework of choice for building production-grade React applications — from marketing sites to complex SaaS platforms.
What’s New in Next.js 14
Next.js 14 introduces the stable App Router with nested layouts, React Server Components by default, server actions for form handling, partial prerendering for optimal performance, and improved Turbopack for faster local development.
App Router: A New Mental Model
The App Router uses a file-system based routing paradigm. Each folder in the app directory represents a route segment. Special files like page.js, layout.js, loading.js, and error.js define the UI for each route. Nested layouts persist across navigations while only the page content re-renders — delivering exceptional performance.
