unplugin-dts

An unplugin that generates declaration files (*.d.ts) from .ts(x) or .vue source files when using library mode.

Installation

pnpm i -D unplugin-dts

Quick Start

import dts from 'unplugin-dts/vite'

export default defineConfig({
  plugins: [dts()],
})

Supports Vite, Rollup, Rolldown, Webpack, Rspack and Esbuild.

When moduleFormat is omitted, the plugin preserves TypeScript's declaration extensions: .ts → .d.ts, .mts → .d.mts, and .cts → .d.cts, including declaration maps.

Declaration maps preserve absolute file:// source URLs, including Windows cross-drive paths, across all output directories.

For dual ESM/CommonJS declarations, explicitly configure two outDirs entries with moduleFormat: 'esm' and moduleFormat: 'cjs'. With bundleTypes, each entry is bundled once and the self-contained result is reused for both declaration formats. Configure conditional exports.types entries separately in package.json.
