Next.js 13 introduces several bleeding-edge features, including the app directory, Streaming, Suspense, and hybrid Server and Client Components. These features make building the next generation of web applications more intuitive for developers. Next.js 13's app directory follows a folder-based hierarchy, allowing for nested layouts and improved routing flexibility. The new architecture also enables progressive adoption, allowing developers to upgrade from previous versions of Next.js while maintaining compatibility with existing codebases. Streaming SSR allows for immediate rendering of UI components without waiting for all data to be fetched, reducing TTFB and FCP times. Suspense boundaries can be defined manually for granular control over data-aware UI components. WunderGraph acts as an API gateway and Backend-for-Frontend, providing end-to-end typesafety and a consistent developer experience. Next.js 13 is still in beta, but its features are incredibly useful for building user-friendly and accessible applications.
