arch-tsdown

arch-tsdown is a TypeScript library starter (based on antfu/starter-ts) that uses tsdown for building. It provides a minimal, opinionated setup: ESM-only output, automatic .d.ts generation, pnpm, Vitest, ESLint, and optional npm Trusted Publisher for CI-based releases.

The skill is based on starter-ts (arch-tsdown source), generated at 2026-01-30.

Recommended practices:

• Build pure ESM; enable dts and exports in tsdown config

• Use npm Trusted Publisher for releases

• Run publint (via tsdown’s publint: true) before publishing
