What build tools are recommended by this skill?

The skill focuses on modern, high-performance tools like tsdown for standard builds and unbuild for more complex, multi-entrypoint library requirements.

Can I use this for Nuxt module development?

While this skill covers general TypeScript library patterns, it is recommended to use the dedicated 'nuxt-modules' skill for Nuxt-specific integrations.

Does it handle dual-format publishing?

Yes, it includes detailed guidance on configuring package.json exports to ensure your library works seamlessly for both CommonJS and ES Modules consumers.

Does this skill support monorepo setups?

Yes, it provides patterns and configurations suitable for both single-package and monorepo TypeScript projects, focusing on modern package resolution.

How does it help with API design?

It provides templates for common library patterns such as builder, factory, and plugin architectures, ensuring high levels of type safety and developer experience.

Developer Tools

Streamlines the creation of high-quality, dual-format TypeScript libraries using industry-standard patterns and modern build tooling.

About

The ts-library skill empowers developers to author production-grade TypeScript libraries by providing expert guidance on project architecture, package exports (CJS/ESM), and modern build tools like tsdown and unbuild. It leverages patterns extracted from top-tier ecosystem libraries such as Vitest and Zod to ensure type-safe API designs, efficient tree-shaking, and robust release workflows, making it an essential companion for building scalable and maintainable open-source or internal packages.

Key Features

Comprehensive Vitest setup for unit and integration testing
Advanced type inference and type-safe API design patterns
249 GitHub stars
Dual-format (CJS/ESM) package export configuration and troubleshooting
Standardized release workflows and CI/CD pipeline integration
Optimized build configurations using tsdown and unbuild

Use Cases

Migrating legacy libraries to ESM-first dual-build systems
Bootstrapping a new open-source TypeScript package with modern defaults
Implementing complex type patterns and builder APIs for developer-friendly tools
