Overview

Next.js App Router is the modern routing paradigm introduced in Next.js 13+ that brings React Server Components, nested layouts, and streaming to production applications. AI coding agents can scaffold routes, generate page and layout components, configure middleware, and set up data fetching patterns using the latest conventions.

With the App Router, your agent understands the file-system-based routing under the `app/` directory, including dynamic segments, route groups, parallel routes, and intercepting routes. It can generate loading states, error boundaries, and not-found pages that follow Next.js conventions automatically, saving you significant boilerplate work.

This skill is essential for any modern React project. AI agents can help you migrate from the Pages Router, implement complex data fetching with `fetch` and caching strategies, set up ISR (Incremental Static Regeneration), and optimize your application for Core Web Vitals out of the box.

Who Is This For?
