# Mnemonic.engine

Creates a Node.js implementation of the [`Mnemonic`](/api/Mnemonic) engine slot, without installing it.

Most callers want [`Engine.install`](/node/crypto/Engine/install) instead, which installs every implementation this entrypoint provides. Reach for this to install or hold the `Mnemonic` slot on its own.

## Imports

:::code-group
```ts [Named]
import { Mnemonic } from 'ox/node'
```

```ts [Entrypoint]
import * as Mnemonic from 'ox/node/Mnemonic'
```
:::

## Examples

```ts twoslash
// @noErrors
import { Engine } from 'ox'
import { Mnemonic } from 'ox/node'

await Engine.install({ Mnemonic: Mnemonic.engine() })

Mnemonic.toSeed(
  'test test test test test test test test test test test junk'
)
```

## Definition

```ts
function engine(): Promise<engine.ReturnType>
```

## Return Type

The raw `Mnemonic` engine slot.

`Promise<engine.ReturnType>`
