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

@pkgr/core publishes both a CommonJS entry and a native ESM entry (ESM added in 0.1.0). require("@pkgr/core") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^14.18.0 || >=16.0.0. import "@pkgr/core" works alongside it.

What to do

  1. Nothing to change. require("@pkgr/core") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^14.18.0 || >=16.0.0. import * as core from "@pkgr/core" works alongside it; use named imports for what the ESM entry exports.
  2. TypeScript: types are bundled; install nothing extra.
