node.js generate UUID + NanoID

no need to import uuid module; node.js embedded crypto can do the job

3 efficient ways to generate UUID in Node.js

import crypto from 'node:crypto'; console.log(crypto.randomUUID()); 00a6fa25-df29-4701-9077-557932591766

ai/nanoid: A tiny (130 bytes), secure, URL-friendly, unique string ID generator for JavaScript

A tiny, secure, URL-friendly, unique string ID generator for JavaScript.

“An amazing level of senseless perfectionism, which is simply impossible not to respect.”

• Small. 130 bytes (minified and gzipped). No dependencies. Size Limit controls the size.
• Safe. It uses hardware random generator. Can be used in clusters.
• Short IDs. It uses a larger alphabet than UUID (A-Za-z0-9_-). So ID size was reduced from 36 to 21 symbols.
• Portable. Nano ID was ported to 20 programming languages.

import { nanoid } from 'nanoid'
model.id = nanoid() //=> "V1StGXR8_Z5jdHi6B-myT"
