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.
npm install useintersectionobserver-react-hooknpm i useintersectionobserver-react-hook
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)
