useIntersectionObserver-React-Hook

This is a custom React hook that simplifies the process of using the Intersection Observer API to detect when an element is visible within the viewport. It is useful for lazy-loading images or other resources, as well as for implementing "infinite scroll" pagination.

Installation

Install using npm:

npm i useintersectionobserver-react-hook

Usage

Import the useIntersectionObserver hook and use it in your component:

``jsx
import { useIntersectionObserver } from 'useintersectionobserver-react-hook'

function MyComponent() {
const [targetRef, isIntersecting] = useIntersectionObserver()

return (

{isIntersecting ? 'Element is visible' : 'Element is not visible'}

)
}
`

You can also pass options to the hook, such as the root element, root margin, and threshold:

`jsx
const options = {
root: null,
rootMargin: '0px',
threshold: 1.0
}

const [targetRef, isIntersecting] = useIntersectionObserver(options)
``

If you don't pass the options to the hook, the ones above will be applied by default.
