nextjs turbo build

# Next.js + Turbopack App Directory Playground [Turbopack](https://turbo.build/pack) is a new incremental bundler optimized for JavaScript and TypeScript, written in Rust by the creators of Webpack and Next.js at [Vercel](https://vercel.com). On large applications Turbopack updates 10x faster than Vite and 700x faster than Webpack ([benchmark](https://turbo.build/pack/pack/docs/benchmarks)). For the biggest applications the difference grows even more stark with updates up to 20x faster than Vite. This playground is a mirror of the [Next.js v13 App Directory Playground](https://github.com/vercel/app-playground), but uses Turbopack as the Next.js development server (`next dev --turbo`). **As a reminder, Turbopack is currently in alpha and not yet ready for production. We appreciate your ongoing support as we work to make it ready for everyone.** ## Running Locally 1. Install dependencies: `yarn` 1. Start the dev server: `yarn dev` **Note:** The playground uses [Tailwind CSS](https://tailwindcss.com). However, Turbopack does not yet support fully [PostCSS](https://turbo.build/pack/docs/features/css#postcss), but it does support CSS and CSS Modules. [As a workaround](https://turbo.build/pack/docs/features/css#tailwind-css), we run Tailwind through it's CLI upon `postinstall`. For live reload of CSS, you can run Tailwind in another process with the `--watch` flag or install `concurrently` and modify your `dev` script: ```bash yarn install concurrently --dev ``` Then modify your `dev` script in `package.json`: ```json { "scripts": { "dev": "concurrently \"next dev --turbo\" \"npm run tailwind --watch\"" } } ``` For more information, see: https://turbo.build/pack/docs/features/css#tailwind-css ## Documentation https://nextjs.link/with-turbopack ## Providing Feedback https://nextjs.link/turbopack-feedback
