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
