uuid ​

Problem ​

You need a random UUID v4 — for example generating unique IDs for new entities before persisting them.

Solution ​

Use uuid() as a thin wrapper around crypto.randomUUID().

ts
import { uuid } from '@vielzeug/arsenal';

uuid(); // e.g. '110e8400-e29b-41d4-a716-446655440000'

const newUser = { id: uuid(), name: 'Alice' };

Pitfalls ​

  • Requires the Web Crypto API (crypto.randomUUID). Available in all modern browsers and Node.js ≥ 19. In older Node.js versions use require('crypto').randomUUID() directly.
