Migrating from Next.js Pages Router to App Router requires restructuring your project around nested layouts and Server Components. This Skill provides structured guidance and best practices to transition existing routes, implement Server Actions, and adapt data fetching for the new architecture.

Server Components handle data fetching directly on the server by executing async functions within the component. This Skill outlines patterns for optimizing data fetching and caching strategies to build scalable web apps with improved SEO.

Parallel routes allow you to simultaneously render multiple pages within a single layout using named slots. This Skill demonstrates code examples for parallel routes to help you build modular layouts and stream data efficiently.

Next.js App Router supports streaming to progressively send UI chunks to the client. This Skill provides code examples showing how to combine streaming with Server Components to optimize performance and render data as it becomes available.

You should use Server Actions to handle form submissions and mutations securely on the server without creating dedicated API routes. This Skill offers best-practice recommendations for implementing Server Actions within your App Router architecture.

Using App Router introduces constraints like adapting to new caching behaviors and learning parallel routes for complex layouts. This Skill helps navigate these architecture decisions and edge cases when building full-stack apps with SSR and SSG.
