🔄 Migration Guide

Node.js version

Upgrade to Node.js 22.18.0 or later. Bun and Deno remain supported (experimental).

unrun is no longer bundled

If your environment relies on the unrun config loader (i.e. you're on a Node version without native TypeScript support and use the default auto loader), install it manually:

npm i -D unrun
# or, alternatively, the new tsx loader:
npm i -D tsx

If you use Node.js 22.18.0+ with native TypeScript support, no change is needed — the auto loader will pick native.

Summary by cubic

Upgrade dev build tool tsdown from 0.21.10 to 0.22.1, adopting rolldown 1.x and improved DTS handling for more reliable builds.

• Migration
  • Requires Node.js 22.18.0+.
  • If you relied on the unrun TypeScript config loader on older Node, install tsx or unrun as a dev dependency. On Node 22.18.0+, the auto loader uses the native TS loader and no action is needed.
