Is @babel/runtime-corejs3 ESM-only? Can you require() it?

babel's modular runtime helpers with core-js@3 polyfilling

Dual (CommonJS + ESM) Dual package, subpaths only — require("@babel/runtime-corejs3/…") works, require("@babel/runtime-corejs3") does not

@babel/runtime-corejs3 exposes only subpaths in its exports map, for example "@babel/runtime-corejs3/helpers/get"; there is no root entry, so require("@babel/runtime-corejs3") and import "@babel/runtime-corejs3" both throw ERR_PACKAGE_PATH_NOT_EXPORTED. Each subpath ships a CommonJS and a native ESM build, so require("@babel/runtime-corejs3/helpers/get") and import "@babel/runtime-corejs3/helpers/get" both work.

What to do

  1. Load subpaths, never the bare name: const runtimeCorejs3 = require("@babel/runtime-corejs3/helpers/get") or import from "@babel/runtime-corejs3/helpers/get". require("@babel/runtime-corejs3") throws ERR_PACKAGE_PATH_NOT_EXPORTED.
  2. TypeScript: no types are available for @babel/runtime-corejs3; declare the module yourself if you need them.

A failing require() on a CommonJS package usually means the package needs a browser/DOM global, a peer dependency, or a native binary that is not available in a bare Node.js process.

Frequently asked

Is @babel/runtime-corejs3 ESM-only?

@babel/runtime-corejs3@8.0.0 ships CommonJS and ESM builds, reachable only through subpaths. @babel/runtime-corejs3 exposes only subpaths in its exports map, for example "@babel/runtime-corejs3/helpers/get"; there is no root entry, so require("@babel/runtime-corejs3") and import "@babel/runtime-corejs3" both throw ERR_PACKAGE_PATH_NOT_EXPORTED. Each subpath ships a CommonJS and a native ESM build, so require("@babel/runtime-corejs3/helpers/get") and import "@babel/runtime-corejs3/helpers/get" both work.

Can I require @babel/runtime-corejs3?

Only by subpath. require("@babel/runtime-corejs3") throws ERR_PACKAGE_PATH_NOT_EXPORTED because the exports map has no root entry; require("@babel/runtime-corejs3/helpers/get") works, and so does import from the same subpath.

Does @babel/runtime-corejs3 work in Bun?

Importing @babel/runtime-corejs3 failed in Bun 1.4.0 on Sep 9, 2026: error: Cannot find module '@babel/runtime-corejs3' from '/Users/boat/Projects/top-seo/data/probe-work/@babel__runtime-corejs3/imp.mjs'

Does @babel/runtime-corejs3 ship TypeScript types?

No. @babel/runtime-corejs3 ships no type declarations and there is no @types package for it.
