crypto.randomBytes()
to generate a UUID, compliant with RFC4122 version 4.Number.prototype.toString()
to convert it to a proper UUID (hexadecimal string).crypto.randomUUID()
provides similar functionality.const crypto = require('crypto');
const UUIDGeneratorNode = () =>
([1e7] + -1e3 + -4e3 + -8e3 + -1e11).replace(/[018]/g, c =>
(c ^ (crypto.randomBytes(1)[0] & (15 >> (c / 4)))).toString(16)
);
UUIDGeneratorNode(); // '79c7c136-60ee-40a2-beb2-856f1feabefc'
