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](references/config.md) | | Format, target, dts, exports, validation | [output.md](references/output.md) | | Shims, unbundle, watch, frameworks, WASM | [features.md](references/features.md) | | Plugins, hooks, lint, programmatic, migration | [advanced.md](references/advanced.md) |

Loading Files

**Consider loading these reference files based on your task:**

  • [ ] [references/config.md](references/config.md) - if setting up tsdown.config.ts, CLI, or entry points
  • [ ] [references/output.md](references/output.md) - if configuring output format, target, .d.ts, exports, or validation
  • [ ] [references/features.md](references/features.md) - if using shims, unbundle, watch mode, framework integrations, or WebAssembly
  • [ ] [references/advanced.md](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.
