CommonJS CommonJS — require() works on every Node.js version we test

@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.

How to import @eslint/js

ES modules (import)

import js from "@eslint/js";

Named imports from a CommonJS package only work when Node.js can statically detect them. If a named import fails, use the default import and destructure.

CommonJS (require)

const js = require("@eslint/js");

Module format by version

Derived from the type, main and exports fields of every stable release on npm, corrected where a runtime test of that version contradicted them (78 versions; the newest 60 shown).
