ESM-only ESM-only since 18.0.0 — last CommonJS version is 17.24.0

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.

How to import eslint-plugin-n

ES modules (import)

import * as eslintPluginN from "eslint-plugin-n";

// Node.js 20.19+, 22.12+ and newer (verified):
const eslintPluginN = require("eslint-plugin-n");

// Any Node.js version the package supports (^20.19.0 || ^22.13.0 || >=24), from an async function:
async function main() {
  const eslintPluginN = await import("eslint-plugin-n");
}

// Or pin the last CommonJS release (declares Node.js ^18.18.0 || ^20.9.0 || >=21.1.0):
// npm install eslint-plugin-n@17.24.0
