# Is jasmine-node ESM-only? Can you require() it?

> jasmine-node@3.0.0 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

DOM-less simple JavaScript BDD testing framework for Node

Last verified Sep 9, 2026 against jasmine-node@3.0.0.

jasmine-node ships CommonJS only. require("jasmine-node") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "jasmine-node" 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("jasmine-node") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
2. From ES modules use the default import: import jasmineNode from "jasmine-node"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/jasmine-node
