Next.js Playground is a GitHub repository maintained by the Next.js DX team for exploring, testing, and demoing new Next.js features before they are documented.
What is Next.js Playground?
Next.js Playground is a minimal, runnable Next.js app designed specifically for the DX team to experiment with framework capabilities. It takes no user input and produces a local development server that showcases several modern App Router concepts: nested layouts, instant loading states, streaming, and component-level data fetching. The project is built with Next.js and React, and its GitHub topics include Vercel, reflecting its place in the Vercel ecosystem.
Key Features
- Nested layouts — Demonstrates how to compose layouts within layouts using the Next.js App Router, enabling shared UI across multiple routes.
- Instant loading states — Shows how to give users immediate feedback during navigation using loading.tsx conventions or Suspense boundaries.
- Streaming — Illustrates server-side streaming of HTML and React components, so page content renders progressively without blocking.
- Component-level data fetching — Displays patterns for fetching data directly inside a component rather than only at the page level, using async components or data hooks.
- pnpm-based setup — Uses pnpm as the package manager; you can start exploring with just two commands:
pnpm install and pnpm dev.
Who is it for?
- Next.js DX team members — use the playground to experiment with unreleased or upcoming framework features in a controlled environment.
- Documentation writers — use the running examples as a starting point for writing accurate, hands-on documentation.
- Next.js developers — explore concrete implementations of nested layouts, loading states, streaming, and data fetching to learn App Router patterns.
- Framework feedback contributors — identify bugs and provide feedback to the Next.js team based on real usage.
What can you do with Next.js Playground?
- Explore new features: test how nested layouts and streaming behave before adopting them in production applications.
- Write documentation: reference the code to create step-by-step guides that match actual framework behavior.
- Report bugs: run edge cases in the playground and file issues with reproducible examples.
- Demo to others: present new Next.js capabilities to teams or at meetups using a ready-to-run app.
How does Next.js Playground work?
- Clone or download the repository.
- Run
pnpm install to install dependencies.
- Run
pnpm dev to start the development server.
Then open the printed local URL to see the examples in the browser.
FAQ
Is Next.js Playground a production-ready template?
No — it is explicitly a playground for exploration and testing, not a starter for building real applications.
What Next.js features does it demonstrate?
It covers nested layouts, instant loading states, streaming, and component-level data fetching, all key App Router concepts.
How do I run it locally?
