🔄 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 },
})

v0.21.0 - Notable Changes

Breaking Changes

Dependency options renamed to deps namespace

The dependency-related options have been moved under a new deps namespace with clearer names:

• external -> deps.neverBundle
• noExternal -> deps.alwaysBundle
• inlineOnly -> deps.onlyAllowBundle
• skipNodeModulesBundle -> deps.skipNodeModulesBundle

Before:

export default defineConfig({
  external: ['vue'],
  noExternal: ['lodash'],
})

After:

export default defineConfig({
  deps: {
    neverBundle: ['vue'],
    alwaysBundle: ['lodash'],
  },
})

The old options still work but are deprecated and will emit warnings.

failOnWarn default changed from 'ci-only' to false

If you relied on the previous behavior where warnings would fail the build in CI environments, you now need to explicitly set failOnWarn: true or failOnWarn: 'ci-only' in your config.

Node.js < 22.18.0 deprecated

tsdown now emits a deprecation warning when running on Node.js versions below 22.18.0. Plan to upgrade your Node.js version accordingly.

New Features

Experimental Node.js SEA executable bundling (exe)

tsdown can now bundle your TypeScript project into a standalone executable using Node.js Single Executable Applications (SEA). A new @tsdown/exe package provides cross-platform executable building support. See the exe documentation for details.

export default defineConfig({
  exe: true, // or { useCodeCache: true, useSnapshot: true }
})

Full CSS pipeline with @tsdown/css

CSS handling has been reimplemented as a native Rolldown plugin and extracted into the @tsdown/css package, providing a complete CSS pipeline with Lightning CSS and PostCSS support via the css.transformer option. See the CSS documentation for details.

inlinedDependencies field in package.json

When using the exports feature, tsdown now auto-generates an inlinedDependencies field in your package.json, listing dependencies that are bundled into the output.

Object option for customExports

customExports now supports an object format for more fine-grained control over the generated exports field.

Migration Guide

1. Update dependency options: Rename external -> deps.neverBundle, noExternal -> deps.alwaysBundle, etc.
2. Check failOnWarn: If you need warnings to fail the build in CI, explicitly set failOnWarn: 'ci-only' or failOnWarn: true.
3. Upgrade Node.js: Ensure you're running Node.js >= 22.18.0 to avoid deprecation warnings.
