# Engine.load

Creates and installs every Node.js implementation this entrypoint provides.

The function is asynchronous to match the `ox/wasm` entrypoint, even though Node's built-in cryptography needs no compilation. Call it once during startup, before any cryptographic operation.

## Imports

```ts [Named]
import { Engine } from 'ox/node'
