react-useportal

usePortal

⏱ A React hook for using Portals

Struggling with modals, lightboxes or loading bars in React? React-portal creates a new top-level React tree and injects its children into it. That's necessary for proper styling (especially positioning).

Installation

yarn add react react-dom react-useportal

Usage

Stateless

import usePortal from 'react-useportal'

<Portal>
  This text is portaled at the end of document.body!
</Portal>

<Portal bindTo={document && document.getElementById('san-francisco')}>
  This text is portaled into San Francisco!
</Portal>

With State

import usePortal from 'react-useportal'

const App = () => {
  const { openPortal, closePortal, Portal } = usePortal()
  return (
    <React.Fragment>
      <button onClick={openPortal}>
        Open Portal
      </button>
      <Portal>
        <p>
          This is more advanced Portal. It handles its own state.{' '}
          <button onClick={closePortal}>Close me!</button>, hit ESC or
          click outside of me.
        </p>
      </Portal>
    </React.Fragment>
  )
}
