Passing ref node to the onChange callback fn in useIntersectionObserver

[tengweiherr]

Context
Since the breaking change in the useIntersectionObserver hook in v2.13.0, we no longer have to pass a ref to the hook. Instead, it exports the callback ref for us to bind to the DOM node. However, using the callback ref loses the ref node access at the same time. For instance, the user might want to have some side effects on the ref node itself when it is intersecting. It would be helpful if the ref node were passed to the onChange callback so we have access to it

Changes

• pass ref node to the onChange callback in useIntersectionObserver
• add type parameter so that the node passed to the callback fn will receive the correct type

Example

const { ref } = useIntersectionObserver<HTMLDivElement>({
  freezeOnceVisible: true,
  onChange: (isIntersecting, _, node) => {
    if (node !== null) {
      node.style.height = isIntersecting ? 'auto' : `100px`
    }
  },
})
