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

@eslint-community/regexpp publishes both a CommonJS entry and a native ESM entry (ESM added in 3.2.0). require("@eslint-community/regexpp") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^12.0.0 || ^14.0.0 || >=16.0.0. import "@eslint-community/regexpp" works alongside it.

What to do

  1. Nothing to change. require("@eslint-community/regexpp") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^12.0.0 || ^14.0.0 || >=16.0.0. import * as regexpp from "@eslint-community/regexpp" works alongside it; use named imports for what the ESM entry exports.
  2. TypeScript: types are bundled; install nothing extra.
