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.
