You can use this utility to customize the timeout of delayed hydration components based on network idle time.

## Parameters

- `timeout` : `number`

## Example

If you would like to give a timeout of 5 seconds for the components:

```vue [pages/index.vue]
<template>
  <div>
    <LazyIdleMyComponent :hydrate="createIdleLoader(5000)"/>
  </div>
<template>
```
::read-more{to="/docs/guide/directory-structure/components#delayed-hydration"}
::

::read-more{to="https://developer.mozilla.org/en-US/docs/Web/API/Window/requestIdleCallback"}
This is based on the `requestIdleCallback` web API, and therefore only accepts the time in milliseconds for the max idle callback duration, which should be a number.
