# Is eslint-plugin-babel ESM-only? Can you require() it?

> eslint-plugin-babel@5.3.1 declares a CommonJS entry, but require() fails at runtime. CommonJS on paper — require() failed in our runtime test.

Last verified Sep 9, 2026 against eslint-plugin-babel@5.3.1.

eslint-plugin-babel declares a CommonJS entry only, but require("eslint-plugin-babel") failed on every Node.js version in our probe: TypeError: (intermediate value).getRules is not a function. import "eslint-plugin-babel" resolves to the same file, so it fails the same way. That usually means a missing peer dependency, a browser-only global, or a package that is not meant to be loaded directly; see the runtime table below.

## What to do

1. require("eslint-plugin-babel") failed in our probe on every Node.js version (TypeError: (intermediate value).getRules is not a function); check the package README for peer dependencies or setup before relying on it.
2. From ES modules use the default import: import eslintPluginBabel from "eslint-plugin-babel"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for eslint-plugin-babel; declare the module yourself if you need them.
