Package Exports

react-useportal

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-useportal) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

usePortal

🌀 React hook for using Portals

Need to make dropdowns, lightboxes/modals/dialogs, global message notifications, or tooltips in React? React Portals provide a first-class way to render children into a DOM node that exists outside the DOM hierarchy of the parent component (react docs).

Examples

Code Sandbox Example

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, isOpen, Portal } = usePortal()
  return (
    <React.Fragment>
      <button onClick={openPortal}>
        Open Portal
      </button>
      {isOpen && (
        <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>
  )
}

Need Animations?

import usePortal from 'react-useportal'

const App = () => {
  const { openPortal, closePortal, isOpen, Portal } = usePortal()
  return (
    <React.Fragment>
      <button onClick={openPortal}>
        Open Portal
      </button>
      <Portal>
        <p className={isOpen ? 'animateIn' : 'animateOut'}>
          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>
  )
}

Options

Option	Description
`closeOnOutsideClick`	This will close the portal when not clicking within the portal. Default is `true`
`closeOnEsc`	This will allow you to hit ESC and it will close the modal. Default is `true`
`renderBelowClickedElement`	This will put the portal right under the element that you click on. Great for dropdowns.
