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.
Fast. It is 2 times faster than UUID.
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"

Supports modern browsers, IE with Babel, Node.js and React Native.
