# Is eslint-module-utils ESM-only? Can you require() it?

> eslint-module-utils@2.14.0 is a CommonJS package, reachable only through subpaths. CommonJS, subpaths only — require("eslint-module-utils/…") works, require("eslint-module-utils") does not.

Core utilities to support eslint-plugin-import and other module-related plugins.

Last verified Sep 9, 2026 against eslint-module-utils@2.14.0.

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

## What to do

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

## Frequently asked

**Is eslint-module-utils ESM-only?**

eslint-module-utils@2.14.0 is a CommonJS package, reachable only through subpaths. eslint-module-utils exposes only subpaths in its exports map, for example "eslint-module-utils/hash"; there is no root entry, so require("eslint-module-utils") and import "eslint-module-utils" both throw ERR_PACKAGE_PATH_NOT_EXPORTED. The subpaths are CommonJS: require("eslint-module-utils/hash") works everywhere, and import "eslint-module-utils/hash" works through Node's CommonJS interop.

**Can I require eslint-module-utils?**

Only by subpath. require("eslint-module-utils") throws ERR_PACKAGE_PATH_NOT_EXPORTED because the exports map has no root entry; require("eslint-module-utils/hash") works.

**Can I import eslint-module-utils with ES module syntax?**

Yes. import eslintModuleUtils from "eslint-module-utils/hash" 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 eslint-module-utils work in Bun?**

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