nextjs-dynamic-routes-params
by wsimmonds
Guide for Next.js App Router dynamic routes and pathname parameters. Use when building pages that depend on URL segments (IDs, slugs, nested paths), accessing the params prop, or fetching resources by identifier. Helps avoid over-nesting by defaulting to the simplest route structure (e.g., app/[id] instead of app/products/[id] unless the URL calls for it).
nextjs-server-navigation
by wsimmonds
Guide for implementing navigation in Next.js Server Components using Link component and redirect() function. Covers the difference between server and client navigation methods. Use when adding links, redirects, or navigation logic in server components without converting them to client components unnecessarily.
nextjs-pathname-id-fetch
by wsimmonds
Focused pattern for fetching data using URL parameters in Next.js. Covers creating dynamic routes ([id], [slug]) and accessing route parameters in server components to fetch data from APIs. Use when building pages that display individual items (product pages, blog posts, user profiles) based on a URL parameter. Complements nextjs-dynamic-routes-params with a simplified, common-case pattern.

by wsimmonds
Guide for advanced Next.js App Router patterns including Route Handlers, Parallel Routes, Intercepting Routes, Server Actions, error boundaries, draft mode, and streaming with Suspense. CRITICAL for server actions (action.ts, actions.ts files, 'use server' directive), setting cookies from client components, and form handling. Use when requirements involve server actions, form submissions, cookies, mutations, API routes, route.ts, parallel routes, intercepting routes, or streaming. Essential for separating server actions from client components.
nextjs-anti-patterns
by wsimmonds
Identify and fix common Next.js App Router anti-patterns and mistakes. Use when reviewing code for Next.js best practices, debugging performance issues, migrating from Pages Router patterns, or preventing common pitfalls. Activates for code review, performance optimization, or detecting inappropriate useEffect/useState usage. CRITICAL: For browser detection, keep the logic in the user-facing component (or a composed helper that it renders) rather than isolating it in unused files.
nextjs-app-router-fundamentals
by wsimmonds
Guide for working with Next.js App Router (Next.js 13+). Use when migrating from Pages Router to App Router, creating layouts, implementing routing, handling metadata, or building Next.js 13+ applications. Activates for App Router migration, layout creation, routing patterns, or Next.js 13+ development tasks.
nextjs-use-search-params-suspense
by wsimmonds
Pattern for using useSearchParams hook with Suspense boundary in Next.js.

Use when building search interfaces, filters, pagination, or any feature that needs to read/manipulate URL query parameters client-side.
nextjs-server-client-components
by wsimmonds
Guide for choosing between Server Components and Client Components in Next.js App Router. CRITICAL for useSearchParams (requires Suspense + 'use client'), navigation (Link, redirect, useRouter), cookies/headers access, and 'use client' directive.
