nanoid

Unique ID generator

FreeLibraries & build toolinggithub.com

What it is

A tiny URL-safe unique ID generator, v6, around 130 bytes gzipped. It uses the platform crypto RNG and produces shorter IDs than UUID v4 at comparable collision safety, with configurable length and alphabet.

Why it earns a slot

You need client-side IDs the moment you do optimistic updates or need React list keys before the server responds. Math.random() collides and Date.now() collides inside loops.

Know before you commit

Modern browsers have built-in crypto.randomUUID() — if you do not need short IDs or a custom alphabet, you may not need the dependency at all.
