bunchee is a zero-configuration bundler for JavaScript/TypeScript npm packages, powered by Rollup and SWC. It uses the package.json `exports` field as the single source of truth to build ESM, CJS, or dual-format output with auto-generated TypeScript declarations.

Use cases

• bundle an npm package with zero config
• build a TypeScript library with ESM and CJS output
• generate TypeScript declaration files automatically
• build a React component library
• package a monorepo shared library
• build a Node.js CLI tool package
• handle use client and use server directives in React Server Components

When to choose

• you want package.json exports to drive the build with no bundler config
• you need dual ESM/CJS output or wildcard subpath exports
• you're building npm packages, component libraries, or monorepo workspaces
• you need RSC directive handling and native .node addon support

When to avoid

• you need highly customized bundler pipelines or exotic plugins
• you're bundling a full web application rather than a library package
• you need output targets older than ES2022 without extra configuration
