# Is @testing-library/dom ESM-only? Can you require() it?

> @testing-library/dom@10.4.1 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

Simple and complete DOM testing utilities that encourage good testing practices.

Last verified Sep 9, 2026 against @testing-library/dom@10.4.1.

@testing-library/dom ships CommonJS only. require("@testing-library/dom") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=18. import "@testing-library/dom" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

It also declares a "module" field, so bundlers such as webpack, Vite and esbuild pick up an ESM build for tree-shaking.

## What to do

1. require("@testing-library/dom") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=18.
2. From ES modules use the default import: import dom from "@testing-library/dom"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
