# nanoId

Generates a 21-character NanoId from the current RandomValues service.

## Signatures

```ts
export declare const nanoId: Effect.Effect<NanoId, never, RandomValues>;
```

## Why

Effectful generation exposes entropy as a service so production and deterministic test sources are interchangeable.

## Ownership and lifetime

The Effect acquires no persistent resource and consumes one fresh 21-byte buffer owned by the invocation.

## Examples

```ts
import { nanoId } from "@typed/id/NanoId"
import { RandomValues } from "@typed/id/RandomValues"
import { Effect } from "effect"
const id = Effect.provide(nanoId, RandomValues.Default)
```
