A JavaScript implementation of many web standards

Last verified Sep 9, 2026 against jsdom@30.0.1.

jsdom ships CommonJS only. require("jsdom") works on Node.js 22, 24 and 26 but fails on Node.js 18 and 20 (ERR_REQUIRE_ESM). The package declares Node.js ^22.22.2 || ^24.15.0 || >=26.0.0. import "jsdom" 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.

## What to do

1. require("jsdom") works on Node.js 22, 24 and 26 but fails on Node.js 18 and 20 (ERR_REQUIRE_ESM). The package declares Node.js ^22.22.2 || ^24.15.0 || >=26.0.0.
2. From ES modules use the default import: import jsdom from "jsdom"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/jsdom
