tsdown

Rolldown + Oxc powered TypeScript bundler. Drop-in tsup replacement.

When to Use

Building TypeScript libraries
Generating .d.ts declarations
Publishing npm packages
Dual ESM/CJS output
Vue/React component libraries

Quick Start

npm i -D tsdown typescript

// tsdown.config.ts
import { defineConfig } from 'tsdown'

export default defineConfig({
  entry: 'src/index.ts',
  format: 'esm',
  dts: true,
  exports: true,
})

tsdown           # Build
tsdown --watch   # Watch mode

Reference Files

Task	File
Config file, CLI, entry points	config.md
Format, target, dts, exports, validation	output.md
Shims, unbundle, watch, frameworks, WASM	features.md
Plugins, hooks, lint, programmatic, migration	advanced.md

Loading Files

Consider loading these reference files based on your task:

references/config.md - if setting up tsdown.config.ts, CLI, or entry points
references/output.md - if configuring output format, target, .d.ts, exports, or validation
references/features.md - if using shims, unbundle, watch mode, framework integrations, or WebAssembly
references/advanced.md - if writing plugins, using linting/validation, programmatic API, or migrating from tsup

DO NOT load all files at once. Load only what's relevant to your current task.
