**English** | [Русский](./README.ru.md) | [简体中文](./README.zh-CN.md)

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.** 108 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](#other-programming-languages).

```js
import { nanoid } from 'nanoid'
model.id = nanoid() //=> "V1StGXR8_Z5jdHi6B-myT"
```
