SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Slow dev server startup and hot module replacement in large Next.js applications waste developer time, and choosing between Turbopack and webpack for dev and production builds is confusing across Next.js versions. ## Core Features & Use Cases - Turbopack Dev Guidance: Explains that Next.js 16+ runs next dev with Turbopack by default, using incremental bundling and file-system caching for faster restarts. - Bundler Selection: Clarifies when to fall back to webpack (Turbopack bugs or webpack-only plugins) and how production build behavior varies by Next.js version. - Bundle Analysis: Covers the experimental Bundle Analyzer in Next.js 16.1+ for inspecting output and trimming heavy dependencies. - Use Case: A developer notices slow HMR in a large Next.js app; this Skill helps confirm Turbopack is active, the .next cache is intact, and the Bundle Analyzer is used to find oversized dependencies. ## Quick Start Ask the AI to diagnose why your Next.js dev server starts slowly and whether Turbopack caching is configured correctly.

Frequently Asked Questions about nextjs-turbopack

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I enable Turbopack in Next.js development?▼

Turbopack is enabled by default in Next.js 16+ when running next dev, with no extra configuration needed. File-system caching under .next makes restarts significantly faster on large projects.

Turbopack vs webpack for Next.js dev server?▼

Turbopack is the default dev bundler in Next.js 16+ and offers faster cold starts and HMR. Use webpack only if you hit a Turbopack bug or depend on a webpack-only plugin, disabling Turbopack with the appropriate flag for your version.

Does Next.js production build use Turbopack?▼

Production build behavior with next build may use Turbopack or webpack depending on your Next.js version. Check the official Next.js documentation for your specific release to confirm which bundler is used.

Why is my Next.js dev server still slow with Turbopack?▼

Slow dev performance usually means the file-system cache is being cleared unnecessarily or you are on an older Next.js version. Stay on a recent Next.js 16.x release and avoid deleting the .next directory between restarts.

How do I analyze Next.js bundle size?▼

Next.js 16.1+ includes an experimental Bundle Analyzer to inspect output and find heavy dependencies. Enable it via config or experimental flag as documented for your version, then trim large dependencies and improve code-splitting.
