nextjs-15

Next.js 15 App Router routing uses specific file conventions like layout.tsx and page.tsx to structure your application. You create nested layouts, pages, and route groups to establish consistent navigation and data fetching patterns across projects.

Data fetching in Next.js 15 server components supports parallel and streaming approaches. You can implement these strategies directly within your components for practical use cases across dashboards, admin panels, and content applications.

Server actions in Next.js 15 allow you to handle data mutations directly on the server. By following established patterns, you can securely process form submissions and execute backend logic without creating separate API endpoints.

Next.js 15 API routes are managed through route handlers within the App Router. You define these handlers in specific route files to process requests and structure your backend logic alongside your layouts and pages.

A Next.js 15 project skeleton uses loading.tsx and error.tsx files to manage UI states during data fetching. This structure ensures your application handles streaming and errors gracefully within the App Router architecture.
