Dual (CommonJS + ESM) Dual package — require() works on every Node.js version we test; import works too

eslint-scope publishes both a CommonJS entry and a native ESM entry (ESM added in 6.0.0). require("eslint-scope") 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-scope" works alongside it.

What to do

  1. Nothing to change. require("eslint-scope") 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 * as eslintScope from "eslint-scope" works alongside it; use named imports for what the ESM entry exports.
  2. TypeScript: types are bundled; install nothing extra.

How to import eslint-scope

import * as eslintScope from "eslint-scope";

CommonJS (require)

const eslintScope = require("eslint-scope");

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 (28 versions; the newest 28 shown).
