@rehooks/component-size

React hook for determining the size of a component

Note: This is using the new React Hooks API Proposal which is subject to change until React 16.7 final.

You'll need to install react, react-dom, etc at ^16.7.0-alpha.0

Install

yarn add @rehooks/component-size

Usage

import { useRef } from 'react'
import useComponentSize from '@rehooks/component-size'

function MyComponent() {
  let ref = useRef(null)
  let size = useComponentSize(ref)
  // size == { width: 100, height: 200 }
  let { width, height } = size
  let imgUrl = `https://via.placeholder.com/${width}x${height}`

  return (
    <div style={{ width: '100%', height: '100%' }}>
      <img ref={ref} src={imgUrl} />
    </div>
  )
}
