React Portal

This library provides the ability to render children into a node that can exist outside the direct hierarchy of the parent component. React's Portal is specifically tied to the DOM, meaning that React applications that need to portal children to a non-DOM based location are out of luck. These cases range from applications built with React Native to interfacing with WebGL.

| Branch | URL | Build Status | | -------- | ------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------- | | master | https://www.npmjs.com/package/@cala/react-portal | |

Installation

npm install @cala/react-portal --save

Usage

Import components individually.

import { EntrancePortal, ExitPortal, PortalProvider } from '@cala/react-portal';

Or wrap it into a single statement.

import * as ReactPortal from '@cala/react-portal';

In order to use the EntrancePortal and ExitPortal, a single PortalProvider will need to enclose the part of the component tree that uses either Portal component. Here's a very simple example of how to use these three components.

<PortalProvider>
  <div>
    <h1>Hello, World.</h1>
    <EntrancePortal name='one'>I'm in a portal!</EntrancePortal>
    <p>Sample body content.</p>
    <ExitPortal name='one' />
  </div>
</PortalProvider>

The rendered output of the above JSX statement will place the textual content of <EntrancePortal /> at the place of <ExitPortal />. In effect, the rendered output will look something like:

<div>
  <h1>Hello, World.</h1>
  <p>Sample body content.</p>
  I'm in a portal!
</div>
