You can use this utility to customize the conditions through which delayed hydration components would hydrate, based on their visiblity status and properties.
|
|
|
|
## Parameters
|
|
|
|
- `options`: `{ root, rootMargin, threshold }`
|
|
|
|
## Example
|
|
|
|
If you would like to change the threshold of the element:
|
|
|
|
```vue [pages/index.vue]
|
|
<template>
|
|
<div>
|
|
<LazyVisibleMyComponent :hydrate="createVisibleLoader({threshold: 0.2})"/>
|
|
</div>
|
|
<template>
|
|
```

|
|
This is based on the `IntersectionObserver` web API, and therefore only accepts the API's properties. You can specify only part of the properties, while the rest will default to the web API's defaults.
