FAQPage Schema
How do I set up a TypeScript library with ESM-first and dual-format support?▼

To set up a TypeScript library with ESM-first and dual-format support, follow modern project structuring patterns that configure package exports for both module systems. This approach ensures broad consumer compatibility while leveraging native ESM features.

What is the best way to configure build tools like tsdown and unbuild for a TypeScript package?▼

Configuring build tools like tsdown and unbuild for a TypeScript package involves defining compilation targets and entry points to generate optimized, dual-format bundles. This streamlines the build process and ensures correct export resolution.

How does type inference improve API design in TypeScript libraries?▼

Type inference improves API design in TypeScript libraries by automatically deducing complex return types, reducing the need for explicit manual annotations. This creates type-safe, flexible, and user-friendly developer experiences without excessive boilerplate.

Can I use this Skill for monorepo project setup and automated release workflows?▼

Yes, you can use this Skill for monorepo project setup and automated release workflows. It provides specific guidance on structuring monorepos and implementing release strategies to streamline the development lifecycle from setup to publication.

What testing strategies should I use when authoring a high-quality TypeScript library?▼

Effective testing strategies for a high-quality TypeScript library focus on validating type safety, API behavior, and build outputs. Integrating these tests into automated workflows ensures robust and maintainable package releases.
