uuidv4()

Function returns a random uuid v4 in a string form.

Parameters

Parameter	Type	Description
secure (optional)	boolean	By default, `uuidv4()` uses a standard random number generator. If the `secure` option is set to `true`, `uuidv4` uses a cryptographically secure random number generator instead. While this adds security, the `secure` option also makes the function an order of magnitude slower.

Returns

Type	Description
string	Random UUID v4 string

import { uuidv4 } from 'https://jslib.k6.io/k6-utils/1.4.0/index.js';

export default function () {
  const randomUUID = uuidv4();
  console.log(randomUUID); // 35acae14-f7cb-468a-9866-1fc45713149a
