With Bun’s native speed, builds and rebuilds are extremely quick, even in monorepos. Faster feedback loops, higher productivity, calmer flow.\n\n## 🚀 Quick Start\n\nCreate a TypeScript file:\n\n```ts\n// src/index.ts\nexport function greet(name: string): string {\n\treturn `Hello, ${name}!`;\n}\n```\n\nBuild it instantly:\n\n```bash\nbunx bunup\n```\n\nOutputs to `dist/` with ESM and `.d.ts` types.\n\nNeed CommonJS too?\n\n```bash\nbunx bunup --format esm,cjs\n```\n\nWant to generate and sync package exports automatically?\n\n```bash\nbunx bunup --exports\n```\n\n## Scaffold\n\nSpin up a modern, ready-to-publish TypeScript or React component library (or a basic starter) in ~10 seconds:\n\n```bash\nbunx @bunup/cli@latest create\n```\n\nSee more in [Scaffold with Bunup](https://bunup.dev/docs/scaffold-with-bunup).\n\n## Features\n\n- ⚡ **Instant builds** — lightning-fast by default\n- 🎨 **CSS support out of the box** — import CSS directly, with built-in CSS Modules support.\n- 📝 **TypeScript declarations** — clean, accurate `.d.ts` files\n- 🪓 **[Declaration splitting](https://bunup.dev/docs/guide/typescript-declarations#declaration-splitting)** — smaller, cleaner type bundles\n- 🔋 **Batteries included** — auto-exports, unused dependency detection, and more\n- 🏗️ **[Workspace-ready](https://bunup.dev/docs/guide/workspaces)** — build multiple packages from one config and one command\n\nFor more, see the full documentation: https://bunup.dev\n\n## 📚 Examples\n\nCheck out the [examples directory](./examples) for example usage:\n\n- [Simple TypeScript library](./examples/basic)\n- [Workspace with multiple packages](./examples/basic-monorepo)\n- [React component library styled with plain CSS](./examples/react-with-pure-css)\n- [React component library styled with CSS Modules](./examples/react-with-css-modules)\n- [React component library styled with Tailwind CSS](./examples/react-with-tailwindcss)\n\n## ❤️ Contributing\n\nWe welcome contributions!
