# Is enzyme-to-json ESM-only? Can you require() it?

> enzyme-to-json@3.6.2 declares a CommonJS entry, but require() fails at runtime. CommonJS on paper — require() failed in our runtime test.

convert enzyme wrapper to a format compatible with Jest snapshot

Last verified Sep 9, 2026 against enzyme-to-json@3.6.2.

enzyme-to-json declares a CommonJS entry only, but require("enzyme-to-json") failed on every Node.js version in our probe: ERR_PACKAGE_PATH_NOT_EXPORTED. import "enzyme-to-json" 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-to-json") 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 enzymeToJson from "enzyme-to-json"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/enzyme-to-json

## Frequently asked

**Is enzyme-to-json ESM-only?**

enzyme-to-json@3.6.2 declares a CommonJS entry, but require() fails at runtime. enzyme-to-json declares a CommonJS entry only, but require("enzyme-to-json") failed on every Node.js version in our probe: ERR_PACKAGE_PATH_NOT_EXPORTED. import "enzyme-to-json" 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 enzyme-to-json?**

Not in practice. enzyme-to-json declares a CommonJS entry, but require("enzyme-to-json") failed on every Node.js version in our probe: ERR_PACKAGE_PATH_NOT_EXPORTED. Check the package README for peer dependencies or setup before relying on it.

**Can I import enzyme-to-json with ES module syntax?**

Yes. import enzymeToJson from "enzyme-to-json" 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 enzyme-to-json work in Bun?**

Importing enzyme-to-json failed in Bun 1.4.0 on Sep 9, 2026: error: Cannot find module 'cheerio/lib/utils' from '/Users/boat/Projects/top-seo/data/probe-work/enzyme-to-json/node_modules/enzyme/build/Utils.js'

**Does enzyme-to-json ship TypeScript types?**

Not bundled. Install the community types with "npm install -D @types/enzyme-to-json".
