crypto.randomUUID()

[MarZab]

Is there a plan to replace uuid with crypto.randomUUID() ?

Even the library itself recommends it in cases you only need UUIDv4.

71 brought up the possibility of externalizing the generator, which would allow you to use any of the sources. Obviously a breaking change, but there is no need for the library to be included.

The validate command added in 5.2.0 uses uuid for the "rigorous" validation, but that is just a single regex, which would be easy to bring over.

I was playing with emoji support for 6.0, but I think that will end up as a separate library just to keep the complexity down.

This could definitely be 6.0.

Right now short takes two arguments: short(alphabet, options). We could accept a function as options.uuid, and default to crypto.randomUUID() if none is passed (and it is available).

This does limit us to Node 20 support, unless we add specific node-only checks for 14.17.0+ where we would have to require('crypto')...

Actually support for randomUUID only started in Node 19, so it would require passing in 'uuid' regardless.

Added in: v15.6.0, v14.17.0

As of Node 19 it is available on the globalThis. For the older versions we would have to require('crypto').

I wrote a quick proof node script to validate this:

#!/usr/bin/env node
console.log(process.version);
try {
  console.log(crypto.randomUUID());
} catch (e) {
 const crypto = require('crypto');
 console.log('require fallback', crypto.randomUUID());
}

The "fallback" produces a UUID on 14, 16, and 18.

v20.10.0
f93f0bd0-eb12-4eee-8fcc-effc035928f8

v18.18.0
require fallback 742fd1d0-f9b6-4de4-bd75-603f6eb35f1a

v16.20.2
require fallback e05b827e-5ffe-4df3-b67d-fb70b9cec088

v14.21.3
require fallback e6999778-2a7d-4319-b407-381234d9a698

Whether it's worth the logic when the consumer can provide it is a different question.

It also might be better on 6.0.0 to allow the first argument to be an options object.

// Prior to Node 19
const crypto = require('crypto');
const short = require('short-uuid');

// Use flickrBase58 if alphabet not specified in options
const translator = short({ uuid: crypto.randomUUID });
