Node.js

For Node.js 16 & 18, you need to polyfill the Web Crypto API. This is not required in Node.js 20.

import { webcrypto } from "node:crypto";

globalThis.crypto = webcrypto;

Alternatively, add the --experimental-global-webcrypto flag when running Node.

node --experimental-global-webcrypto index.js
