# Is math-intrinsics ESM-only? Can you require() it?

> math-intrinsics@1.1.0 is a CommonJS package, reachable only through subpaths. CommonJS, subpaths only — require("math-intrinsics/…") works, require("math-intrinsics") does not.

ES Math-related intrinsics and helpers, robustly cached.

Last verified Sep 9, 2026 against math-intrinsics@1.1.0.

math-intrinsics exposes only subpaths in its exports map, for example "math-intrinsics/abs"; there is no root entry, so require("math-intrinsics") and import "math-intrinsics" both throw ERR_PACKAGE_PATH_NOT_EXPORTED. The subpaths are CommonJS: require("math-intrinsics/abs") works everywhere, and import "math-intrinsics/abs" works through Node's CommonJS interop.

## What to do

1. Load subpaths, never the bare name: const mathIntrinsics = require("math-intrinsics/abs"). require("math-intrinsics") throws ERR_PACKAGE_PATH_NOT_EXPORTED.
2. From ES modules use the default import: import mathIntrinsics from "math-intrinsics/abs"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for math-intrinsics; declare the module yourself if you need them.

## Frequently asked

**Is math-intrinsics ESM-only?**

math-intrinsics@1.1.0 is a CommonJS package, reachable only through subpaths. math-intrinsics exposes only subpaths in its exports map, for example "math-intrinsics/abs"; there is no root entry, so require("math-intrinsics") and import "math-intrinsics" both throw ERR_PACKAGE_PATH_NOT_EXPORTED. The subpaths are CommonJS: require("math-intrinsics/abs") works everywhere, and import "math-intrinsics/abs" works through Node's CommonJS interop.

**Can I require math-intrinsics?**

Only by subpath. require("math-intrinsics") throws ERR_PACKAGE_PATH_NOT_EXPORTED because the exports map has no root entry; require("math-intrinsics/abs") works.

**Can I import math-intrinsics with ES module syntax?**

Yes. import mathIntrinsics from "math-intrinsics/abs" works in Node.js and Bun because they support importing CommonJS modules. Named imports work only when Node.js can statically detect the exports.

**Does math-intrinsics work in Bun?**

Importing math-intrinsics failed in Bun 1.4.0 on Sep 9, 2026: error: Cannot find package 'math-intrinsics' from '/Users/boat/Projects/top-seo/data/probe-work/math-intrinsics/imp.mjs'

**Does math-intrinsics ship TypeScript types?**

No. math-intrinsics ships no type declarations and there is no @types package for it.
