# Is @jest/globals ESM-only? Can you require() it?

> @jest/globals@30.5.1 declares a CommonJS entry, but require() fails at runtime. CommonJS on paper — require() failed in our runtime test.

Last verified Sep 9, 2026 against @jest/globals@30.5.1.

@jest/globals declares a CommonJS entry only, but require("@jest/globals") failed on every Node.js version in our probe: Do not import `@jest/globals` outside of the Jest test environment. import "@jest/globals" resolves to the same file, so it fails the same way. That usually means a missing peer dependency, a browser-only global, or a package that is not meant to be loaded directly; see the runtime table below.

## What to do

1. require("@jest/globals") failed in our probe on every Node.js version (Do not import `@jest/globals` outside of the Jest test environment); check the package README for peer dependencies or setup before relying on it.
2. From ES modules use the default import: import globals from "@jest/globals"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.

## Frequently asked

**Is @jest/globals ESM-only?**

@jest/globals@30.5.1 declares a CommonJS entry, but require() fails at runtime. @jest/globals declares a CommonJS entry only, but require("@jest/globals") failed on every Node.js version in our probe: Do not import `@jest/globals` outside of the Jest test environment. import "@jest/globals" resolves to the same file, so it fails the same way. That usually means a missing peer dependency, a browser-only global, or a package that is not meant to be loaded directly; see the runtime table below.

**Can I require @jest/globals?**

Not in practice. @jest/globals declares a CommonJS entry, but require("@jest/globals") failed on every Node.js version in our probe: Do not import `@jest/globals` outside of the Jest test environment. Check the package README for peer dependencies or setup before relying on it.

**Can I import @jest/globals with ES module syntax?**

Yes. import globals from "@jest/globals" works in Node.js and Bun because they support importing CommonJS modules. Named imports work only when Node.js can statically detect the exports.

**Does @jest/globals work in Bun?**

Importing @jest/globals failed in Bun 1.4.0 on Sep 9, 2026: error: Do not import `@jest/globals` outside of the Jest test environment

**Does @jest/globals ship TypeScript types?**

Yes. @jest/globals bundles its own type declarations; no @types package is needed.
