uuidv4-gen

A very simple library for generating RFC 4122 UUIDs, variant 4, given a source of randomness.

Usage

On the web:

let uuidv4 = require('uuidv4-gen');
 
let uuid = uuidv4(crypto.getRandomValues.bind(crypto));

In node:

let uuidv4 = require('uuidv4-gen');
let crypto = require('crypto');
function getRandomBytes(buffer) {
  buffer.set(crypto.randomBytes(buffer.length));
}
 
let uuid = uuidv4(getRandomBytes);
