typack

library0.3.0jsnpmunverified

A native TypeScript declaration (.d.ts) bundler built on Oxc, providing fast bundling of TypeScript declaration files. Current stable version is 0.3.0, released periodically on npm. It differentiates from other d.ts bundlers (like @microsoft/api-extractor or dts-bundle-generator) by leveraging Oxc's performance for native-speed parsing and bundling. It supports external module exclusion, sourcemaps, and CJS default export emission. Requires Node.js >= 20.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

bundle

✓ import { bundle } from 'typack'

✗ const { bundle } = require('typack')

typack is ESM-only; use named import. CommonJS require() will not work.

BundleDtsResult

✓ import type { BundleDtsResult } from 'typack'

✗ import { BundleDtsResult } from 'typack'

BundleDtsResult is a type; import it with `import type` or use `import { type BundleDtsResult }`.

BundleOptions

✓ import type { BundleOptions } from 'typack'

✗ import { BundleOptions } from 'typack'

BundleOptions is a type; import it with `import type`.

Bundles a TypeScript declaration file, externalizing 'react', with sourcemap generation.

import { bundle } from 'typack'; const result = bundle({ input: ['src/index.d.ts'], external: ['react'], cwd: process.cwd(), sourcemap: true, cjsDefault: false, }); console.log(result.code); if (result.map) { console.log('Source map generated'); } result.warnings.forEach(w => console.warn(w.message));

Debug

Known issues

breakingNode.js >= 20 is required. Lower versions are not supported.

fix

Upgrade Node.js to version 20 or higher.

affects: <0.0.0

gotchaThe package is ESM-only. CommonJS require() will throw an error.

fix

Use import syntax or set your project to ESM mode.

affects: >=0.0.1

gotchaThe 'input' option accepts an array of strings, but passing a single string (e.g., 'src/index.d.ts') is a common mistake.

fix

Always wrap the entry file in an array: input: ['src/index.d.ts'].

affects: >=0.0.1

deprecatedThe 'cjsDefault' option may be deprecated in future versions as ESM becomes standard.

fix

Avoid relying on CJS-specific output; prefer ESM default exports.

affects: >=0.3.0

Errors

Common errors & fixes

Error [ERR_REQUIRE_ESM]: require() of ES Module /path/to/node_modules/typack/dist/index.js not supported.

Using CommonJS require() to import an ESM-only package.

fix

Change to import { bundle } from 'typack'; or add "type": "module" in package.json.

TypeError: bundle is not a function

Incorrect import (e.g., using default import instead of named import).

fix

Use import { bundle } from 'typack';

Error: Cannot find module 'typack'

Package not installed or Node.js version below 20.

fix

Run npm install typack and ensure Node.js >= 20.
