resize-observer-hook


> A hook that uses Resize Observer API to monitor changes in the size of an element.

 

Install

``bash
npm install resize-observer-hook
`

Usage

`jsx
import React from 'react'

import useResizeObserver from 'resize-observer-hook'

const App = () => {
const [ref, width, height] = useResizeObserver()

return (



)
}
`

You can add multiple ResizeObserverBoxOptions to the useResizeObserver like this ->

`
const [ref,width,height] = useResizeObserver("borderBoxSize");
`

ResizeObserverBoxOptions that are supported currently in the library ->

- borderBoxSize
- contentBoxSize
- contentRect

Note ⚠️ - Some options aren't supported in some broswers so if you provide any option that is not being supported in your current browser, it will automatically use contentRect to calculate height and width of the observed element.
