🔄 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.

dts auto-enabled from tsconfig

If your tsconfig.json has compilerOptions.declaration: true but you do not want tsdown to emit .d.ts files, opt out explicitly:

// tsdown.config.ts
export default defineConfig({
  dts: false,
})

exports.bin auto-detection

Any entry chunk containing a shebang (e.g. #!/usr/bin/env node) now causes tsdown to write a bin field in package.json automatically. The semantics differ slightly from explicit bin: true:

Value	Single shebang	Multiple shebangs	No shebangs
(unset)	Auto-set bin	Warn, skip	Silent
true	Auto-set bin	Throw	Warn
false	No bin	No bin	No bin

To opt out entirely:

export default defineConfig({
  exports: { bin: false },
})

1 issue found across 2 files

Confidence score: 3/5

• package.json introduces a concrete compatibility risk: tsdown 0.22.0 needs a higher Node version than the repo currently declares, which can break build/publish in currently permitted Node 22.x/23 environments.
• This is a medium-severity, high-confidence issue with direct CI/release impact, so there is some merge risk until the Node engine floor and tooling requirements are aligned.
• Pay close attention to package.json - Node engine and dependency version mismatch may cause build/publish failures.
