Does this skill support dual-package exports?

Yes, it provides standard configurations for generating both ESM and CommonJS formats simultaneously to ensure your package works in all Node.js environments.

When should I use tsup versus Vite?

Use tsup for bundling libraries and packages where you need clean exports and dts files. Vite is the recommended choice for building frontend web applications.

Can I use this for CLI applications?

Absolutely. The skill includes specific patterns for configuring tsup with shebangs and banners, as well as optimizing script execution for command-line tools.

How does tsx improve development workflows?

tsx allows you to run TypeScript files directly without a manual compilation step, making it ideal for local scripts, migration tasks, and development servers.
