vuid

very unique identifiers

This module exports a tiny (144B) function that generates UUIDv4 compliant identifiers in the browser. It takes advantages of and relies on the browsers built in crypto API; namely the getRandomValues function. This offers a better level of randomness than Math.random but means will not work in a node environment.

For all practical purposes the generated identifiers can be considered universally unique. The chance of two ever colliding is less than 1 in 5316911983139663491615228241121378304. Which is a pretty cool guarantee.

import vuid from 'vuid'
import vuid from 'https://unpkg.com/vuid'

Usage

Call the imported function.
