SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Streamlines migrating TypeScript library projects from tsup to tsdown by providing complete option mappings, transformation rules, and default-difference guidance so developers can convert configurations confidently.

Core Features & Use Cases

  • Option Mappings: Translate tsup options to their tsdown equivalents to preserve behavior.
  • Config Transformations: Rename inputs, adjust imports, and apply value changes across config files.
  • Default Differences: Highlight tsup-to-tsdown default changes and how to preserve prior behavior.
  • Package.json Migration: Update dependencies, scripts, and root config fields to tsdown equivalents.
  • Migration Guidance: Help teams plan, validate, and test migrations, with post-migration configuration recommendations.

Quick Start

Initiate a migration by applying the tsup→tsdown mappings to your config and updating package.json accordingly.
