bunchee

Bunchee is a zero-config bundler designed to simplify the npm package bundling process for JavaScript and TypeScript developers. It automatically handles multiple output formats including CommonJS and ES modules, with native support for JSX and React Server Components. By eliminating complex configuration requirements, Bunchee reduces setup time and integrates seamlessly into existing development workflows. The tool is particularly beneficial for library authors and maintainers who need to publish packages with multiple module formats without extensive tooling overhead. Bunchee connects directly to npm, streamlining the entire build-to-publish pipeline.

["Install Bunchee globally or as a dev dependency: `npm install -D bunchee` or `pnpm add -D bunchee`.","Run the bundler in your project root: `bunchee` for default settings or `bunchee --out-dir ./dist --format cjs,esm` to customize output.","For TypeScript/JSX projects, ensure your `tsconfig.json` or `jsconfig.json` is properly configured (e.g., `\"jsx\": \"react-jsx\"`).","Verify the output in the specified directory and check the bundle size using tools like `bundlephobia` or `webpack-bundle-analyzer`.","Integrate into CI/CD by adding a build step (e.g., `bunchee && npm publish`) to automate package publishing."]
