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

> node-uuid@1.4.8 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

Rigorous implementation of RFC4122 (v1 and v4) UUIDs.

Last verified Sep 9, 2026 against node-uuid@1.4.8.

node-uuid ships CommonJS only. require("node-uuid") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "node-uuid" 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.

**Deprecated:** Use uuid module instead

## What to do

1. require("node-uuid") 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 nodeUuid from "node-uuid"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/node-uuid
4. This package is deprecated: Use uuid module instead
