What problem does it solve?
Next.js 15 App Router patterns can be verbose and difficult to implement consistently across routes, server actions, and data fetching. This guide provides a structured approach to applying these patterns in real projects.
Core Features & Use Cases
- App Router file conventions (layout.tsx, page.tsx, loading.tsx, error.tsx, not-found.tsx, route groups, api/ route.ts, and private folders) to ensure consistent project structure.
- Server Components and Server Actions: async components and "use server" patterns to separate server and client logic.
- Data fetching patterns: parallel data fetching and streaming with Suspense to optimize UX.
- Middleware, route handlers, and metadata generation to support routing, access control, and SEO.
- Server-only practices and best-practices for robust production apps.
Quick Start
Create a Next.js 15 project following the App Router conventions described here, then implement server components, actions, route handlers, and metadata as you build your app.
