Next.js and Turbopack

Next.js 16+ uses Turbopack by default for local development: an incremental bundler written in Rust that significantly speeds up dev startup and hot updates.

When to Use

Turbopack (default dev): Use for day-to-day development. Faster cold start and HMR, especially in large apps.
Webpack (legacy dev): Use only if you hit a Turbopack bug or rely on a webpack-only plugin in dev. Disable with --webpack (or --no-turbopack depending on your Next.js version; check the docs for your release).
Production: Production build behavior (next build) may use Turbopack or webpack depending on Next.js version; check the official Next.js docs for your version.

Use when: developing or debugging Next.js 16+ apps, diagnosing slow dev startup or HMR, or optimizing production bundles.

How It Works

Turbopack: Incremental bundler for Next.js dev. Uses file-system caching so restarts are much faster (e.g. 5–14x on large projects).
Default in dev: From Next.js 16, next dev runs with Turbopack unless disabled.
File-system caching: Restarts reuse previous work; cache is typically under .next; no extra config needed for basic use.
Bundle Analyzer (Next.js 16.1+): Experimental Bundle Analyzer to inspect output and find heavy dependencies; enable via config or experimental flag (see Next.js docs for your version).

Examples

Commands

next dev
next build
next start

Usage

Run next dev for local development with Turbopack. Use the Bundle Analyzer (see Next.js docs) to optimize code-splitting and trim large dependencies. Prefer App Router and server components where possible.

Best Practices

Stay on a recent Next.js 16.x for stable Turbopack and caching behavior.
If dev is slow, ensure you're on Turbopack (default) and that the cache isn't being cleared unnecessarily.
For production bundle size issues, use the official Next.js bundle analysis tooling for your version.

# Next.js and Turbopack

Next.js 16+ uses Turbopack by default for local development: an incremental bundler written in Rust that significantly speeds up dev startup and hot updates.

## When to Use

- **Turbopack (default dev)**: Use for day-to-day development. Faster cold start and HMR, especially in large apps.
- **Webpack (legacy dev)**: Use only if you hit a Turbopack bug or rely on a webpack-only plugin in dev. Disable with `--webpack` (or `--no-turbopack` depending on your Next.js version; check the docs for your release).
- **Production**: Production build behavior (`next build`) may use Turbopack or webpack depending on Next.js version; check the official Next.js docs for your version.

Use when: developing or debugging Next.js 16+ apps, diagnosing slow dev startup or HMR, or optimizing production bundles.

## How It Works

- **Turbopack**: Incremental bundler for Next.js dev. Uses file-system caching so restarts are much faster (e.g. 5–14x on large projects).
- **Default in dev**: From Next.js 16, `next dev` runs with Turbopack unless disabled.
- **File-system caching**: Restarts reuse previous work; cache is typically under `.next`; no extra config needed for basic use.
- **Bundle Analyzer (Next.js 16.1+)**: Experimental Bundle Analyzer to inspect output and find heavy dependencies; enable via config or experimental flag (see Next.js docs for your version).

## Examples

### Commands

```bash
next dev
next build
next start
```

### Usage

Run `next dev` for local development with Turbopack. Use the Bundle Analyzer (see Next.js docs) to optimize code-splitting and trim large dependencies. Prefer App Router and server components where possible.

## Best Practices

- Stay on a recent Next.js 16.x for stable Turbopack and caching behavior.
- If dev is slow, ensure you're on Turbopack (default) and that the cache isn't being cleared unnecessarily.
- For production bundle size issues, use the official Next.js bundle analysis tooling for your version.

Install targets

Codex install prompt

Install the "nextjs-turbopack" agent skill from https://github.com/loulanyue/awesome-claude-notes/tree/main/.cursor/skills/nextjs-turbopack. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Next.js 16+ and Turbopack — incremental bundling, FS caching, dev speed, and when to use Turbopack vs webpack. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"loulanyue-nextjs-turbopack","task":"Install nextjs-turbopack","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: .cursor/skills/nextjs-turbopack/SKILL.md. Recorded revision: 6c15cfa1999fbc349d51fefe8187ef43cbb21efd. Confirm the source matches these instructions.
