## What it is
An official Vercel playground repository demonstrating Next.js App Router features such as nested layouts, streaming, loading states, caching, and component-level data fetching. It serves as a living example codebase used by the Next.js DX team to test features and as a starting point for developers learning the App Router.

## Use cases
- learn next.js app router features
- see examples of nested layouts in next.js
- understand streaming and loading states in react server components
- demo next.js caching strategies
- find starter code for next.js app router projects
- explore parallel routes and route groups

## When to choose
- you are learning or evaluating the Next.js App Router and want runnable examples
- you need reference implementations of layouts, loading UI, error UI, and caching patterns
- you want a minimal scaffold to experiment with new Next.js features

## When to avoid
- you need a production-ready application template with auth, testing, and CI configured
- you are not using Next.js or React
- you want a comprehensive tutorial course rather than example code

## Facets
- artifact type: learning-resource
