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.** 118 bytes (minified and brotlied). No dependencies.
  [Size Limit] controls the size.
- **Fast.** 50% faster than native `crypto.randomUUID()`.
- **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 over [20 programming languages](./README.md#other-programming-languages).

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