# Is enzyme-adapter-react-16 ESM-only? Can you require() it?

JavaScript Testing utilities for React

Last verified Sep 9, 2026 against enzyme-adapter-react-16@1.15.8.

enzyme-adapter-react-16 declares a CommonJS entry only, but require("enzyme-adapter-react-16") failed on every Node.js version in our probe: ERR_PACKAGE_PATH_NOT_EXPORTED. import "enzyme-adapter-react-16" 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("enzyme-adapter-react-16") failed in our probe on every Node.js version (ERR_PACKAGE_PATH_NOT_EXPORTED); check the package README for peer dependencies or setup before relying on it.
2. From ES modules use the default import: import enzymeAdapterReact16 from "enzyme-adapter-react-16"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/enzyme-adapter-react-16
