Can it handle dual-package exports?

Yes, it can configure your package.json with modern 'exports' maps to support both ESM and CommonJS (CJS) formats simultaneously.

Does it automate the NPM publishing process?

Yes, it provides workflows for semantic versioning (semver), changelog generation, git tagging, and secure publishing to the NPM registry with provenance.

How does it help with bundle size optimization?

It implements advanced strategies such as tree-shaking, code splitting, dependency externalization, and minification using Terser or esbuild to minimize your library's footprint.

Is TypeScript supported out of the box?

Absolutely. It handles tsconfig configuration, type declaration (.d.ts) generation, and ensures type safety throughout the build and distribution process.

What build tools does this skill support?

This skill specializes in modern JavaScript build tools including tsup, Vite, Rollup, and esbuild, as well as traditional configurations for Webpack.

Deployment & DevOps

Configures modern build systems, optimizes bundle sizes, and automates NPM publishing workflows for JavaScript and TypeScript libraries.

Library Bundler is an expert-level skill designed to streamline the creation, optimization, and distribution of component libraries and utility packages. It provides deep integration with modern build tools like tsup, Vite, and Rollup to handle complex multi-format exports (ESM, CJS, UMD) while ensuring minimal bundle footprints through advanced tree-shaking and code-splitting techniques. Whether you are managing a monorepo or a single package, this skill automates the tedious aspects of semantic versioning, TypeScript declaration generation, and NPM registry publication, allowing developers to focus on writing code while maintaining high-quality distribution standards.
