UUIDGeneratorNode

Generates a UUID in Node.JS.

• Use crypto.randomBytes() to generate a UUID, compliant with RFC4122 version 4.
• Use Number.prototype.toString(16) to convert it to a proper UUID.

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'
