How to Generate Unique IDs in JavaScript

Ever wondered to easily generate unique IDs that work in all platforms like browser, Node.js and Deno?

Here is how to do it using the built-in randomUUID() method:

Browser

const uuid = crypto.randomUUID();
console.log(uuid); 
// 👉 56a0640d-148f-48e6-a2b7-8bb83bad64b8

Node - ESM

// const crypto = require('crypto') 
import crypto from 'crypto';
const uuid = crypto.randomUUID();
console.log(uuid); 
// 👉 56a0640d-148f-48e6-a2b7-8bb83bad64b8

Node - CommonJS

const crypto = require('crypto') 
const uuid = crypto.randomUUID();
console.log(uuid); 
// 👉 56a0640d-148f-48e6-a2b7-8bb83bad64b8

Happy generating IDs!
