PK !? [h2` README.mdnu W+A # Nano ID
**English** | [Русский](./README.ru.md) | [简体中文](./README.zh-CN.md) | [Bahasa Indonesia](./README.id-ID.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.** 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](#other-programming-languages).
```js
import { nanoid } from 'nanoid'
model.id = nanoid() //=> "V1StGXR8_Z5jdHi6B-myT"
```
Supports modern browsers, IE [with Babel], Node.js and React Native.
