# [`oro:async_hooks`](/runtime/docs/javascript/async_hooks/)

[`oro:async_hooks`](/runtime/docs/javascript/async_hooks/) exposes hook-based async lifecycle inspection compatible with Node-style instrumentation.

## Examples

Inspect async-resource lifecycles as work is scheduled:

```js
import { createHook, executionAsyncId } from 'oro:async_hooks'

const hook = createHook({
  init(asyncId, type, triggerAsyncId) {
    console.log({ asyncId, type, triggerAsyncId })
  }
})

hook.enable()
queueMicrotask(() => {
  console.log(executionAsyncId())
  hook.disable()
})
```
