SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill clarifies how to implement Next.js 15 App Router patterns, helping teams navigate the complexities of the App Router, Server Components vs Client Components, Server Actions, Route Handlers, caching/revalidation, and streaming/Suspense.

Core Features & Use Cases

  • App Router structure: guidance on app/, layout.tsx, page.tsx, route groups, and route handlers.
  • Component architecture: distinctions and best practices for Server Components and Client Components.
  • Data flow patterns: use Server Actions and Route Handlers to mutate data and fetch data efficiently, with revalidation strategies.
  • Performance & UX: streaming and Suspense patterns to optimize perceived performance.
  • Use Case: Porting an existing Next.js app to Next.js 15 App Router with server components and streaming.

Quick Start

Start by scaffolding a minimal Next.js 15 app with an app/ directory including layout.tsx, a page.tsx, and a route.ts for API using Server Actions.

FAQPage Schema
How do I structure a Next.js 15 app using the App Router?

Next.js 15 App Router structure relies on the app/ directory containing layout.tsx, page.tsx, route groups, and route.ts files. Scaffolding these files establishes foundational routing and API endpoints for your application.

What is the difference between Server Components and Client Components in Next.js 15?

Server Components and Client Components in Next.js 15 distinguish where rendering occurs and how data flows. Server Components fetch data on the server, while Client Components handle interactivity on the client side.

How do I use Server Actions and Route Handlers to mutate data in Next.js 15?

Server Actions and Route Handlers in Next.js 15 mutate data by executing server-side code. Server Actions handle form submissions directly, while Route Handlers manage API endpoints with tailored revalidation strategies.

What is the best way to optimize Next.js 15 performance with streaming and Suspense?

Streaming and Suspense patterns optimize Next.js 15 performance by progressively sending UI chunks to the client. This approach improves perceived performance by rendering components as data becomes available.

Do I need TypeScript to migrate an existing app to the Next.js 15 App Router?

Migrating to the Next.js 15 App Router requires familiarity with Next.js, Node.js, and TypeScript. Applying these patterns and best practices ensures successful implementation of server components and streaming during the porting process.

When should I use revalidation strategies in Next.js 15 Route Handlers?

Revalidation strategies in Next.js 15 Route Handlers are used when fetching data efficiently to ensure cache freshness. They trigger data updates without rebuilding the entire application, maintaining performance while keeping content current.
