NextJS 16+ Complete Documentation

**Quick judgment** High-quality reference skill for anything involving Next.js 16. It embeds the full documentation (including App Router, legacy Pages Router, APIs, architecture, and migration guides) in a well-structured markdown hierarchy. For any agent that needs to reason precisely about Next.js behavior or APIs, this is a strong, low-risk choice. **Strengths** - Very broad coverage of real-world concerns: routing, data fetching, server components/actions, caching, deployment, testing, environment variables, PWAs, and migrations. - Includes both conceptual guides and detailed API reference, enabling explanations, examples, and code-level guidance. - Explicit navigation hints (e.g., where to look for caching, testing, or migration topics) make it straightforward for an agent to locate relevant files. **Key risks / limitations** - The docs are tied to a specific prerelease version (`v16.2.0-canary.30`); behavior and APIs could differ slightly from stable or future Next.js versions. The agent should avoid over-generalizing to older or newer Next.js major versions. - Any experimental or canary features documented here may not match what users see in production projects; responses should be cautious when discussing experimental flags or unstable APIs. - It is read-only documentation; it does not provide automated code transformations, linting, or runtime diagnostics—only information and examples. **Recommended scenarios** - Building or reviewing applications that explicitly target Next.js 16, especially using the App Router and React Server Components. - Answering in-depth questions about configuration, routing, data fetching patterns, caching, or deployment strategies in Next.js. - Guiding users through migrations (Vite/CRA → Next.js, Pages Router → App Router) or upgrades to v16 using official patterns. - Explaining framework internals like the compiler, fast refresh, and supported browsers, to justify architectural decisions or debugging steps.
