# Is @eslint/js ESM-only? Can you require() it?

> @eslint/js@10.0.1 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

ESLint JavaScript language implementation

Last verified Sep 9, 2026 against @eslint/js@10.0.1.

@eslint/js ships CommonJS only. require("@eslint/js") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^20.19.0 || ^22.13.0 || >=24. import "@eslint/js" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("@eslint/js") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^20.19.0 || ^22.13.0 || >=24.
2. From ES modules use the default import: import js from "@eslint/js"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
