uuid-random

uuid-random

Generate random UUIDv4 with better statistical dispersion than Math.random().

Install

npm install uuid-random

Performance

This is the fastest pure javascript UUIDv4 generator I have found, almost 5x faster than comparable libraries.

npm package	performance
uuid	370k ops/sec
node-uuid	370k ops/sec
uuid-random	1.618M ops/sec

Yep, the golden ratio.

Features

• 0.3k minified + gzipped
• Uses better RNG when possible
• Works in browser or node
• Very fast!

Example Usage

Node

var uuid = require('uuid-random');
uuid(); // '0b99b82f-62cf-4275-88b3-de039020f14e'

Browser

<script src="uuid-random.min.js"></script>
<script>
  uuid(); // 'b96ab5e6-f1e8-4653-ab08-4dd82ea65778'
</script>

Rationale

Math.random() sucks for uuid generation.

After digging through npm and stackoverflow, I settled on using node-uuid to take advantage of better RNG when possible.

I wasn't happy with the solution so I combined code from the best libs and researched a much faster, more compact version that still used the best RNG available to the platform.

This library does one thing very well: generate UUIDv4 (random).
