Additional ESLint's rules for Node.js

Last verified Sep 9, 2026 against eslint-plugin-n@18.3.0.

eslint-plugin-n dropped its CommonJS build in 18.0.0 (May 2026). The last version with a plain require()-able CommonJS entry is 17.24.0, published Feb 15, 2026; it declares support for Node.js ^18.18.0 || ^20.9.0 || >=21.1.0.

On Node.js 20.19+, 22.12+ and newer, require("eslint-plugin-n") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. Node.js 18 has no require(esm), and eslint-plugin-n@18.3.0 declares Node.js ^20.19.0 || ^22.13.0 || >=24, so 18 is outside its supported range anyway.

eslint-plugin-n@18.3.0 declares engines "^20.19.0 || ^22.13.0 || >=24", so Node.js 18 is outside its supported range regardless of module format.

## What to do

1. On Node.js 20.19+, 22.12+ and newer, require("eslint-plugin-n") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26.
2. From a CommonJS file, use a dynamic import inside an async function: const eslintPluginN = await import("eslint-plugin-n"). That works on every Node.js version the package supports (^20.19.0 || ^22.13.0 || >=24).
3. If you need a synchronous require() or run Node.js 18: npm install eslint-plugin-n@17.24.0, the last CommonJS release (published Feb 15, 2026); it declares Node.js ^18.18.0 || ^20.9.0 || >=21.1.0.
4. eslint-plugin-n@18.3.0 declares engines "^20.19.0 || ^22.13.0 || >=24", so Node.js 18 is unsupported regardless: upgrade Node.js or pin an older release.
5. TypeScript: types are bundled; install nothing extra.
