English | Русский | 简体中文

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

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