React component for transportation of modals, lightboxes, loading bars... to document.body
npm install react-portal-daniellangnetReact-portal
============
> Struggling with modals, lightboxes or loading bars in React? React-portal creates a new top-level React tree and injects its child into it. That's necessary for proper styling (especially positioning).
- transports its child into a new React component and appends it to the document.body or a custom container (creates a new independent React tree)
- can be opened by the prop isOpen
- can be opened after a click on an element that you pass through the prop openByClickOn (and then it takes care of the open/close state)
- doesn't leave any mess in DOM after closing
- provides its child with this.props.closePortal callback
- provides close on ESC and close on outside mouse click out of the box
- supports absolute positioned components (great for tooltips)
- no dependencies
- fully covered by tests

#### children : ReactElement
The portal expects one child (
) that will be ported.$3
#### isOpen : bool
The V3 version uses
isOpened. Renaming to isOpen is going to be released soon with the V4.If true, the portal is open. If false, the portal is closed. It's up to you to take care of the closing (aka taking care of the state). Don't use this prop if you want to make your life easier. Use openByClickOn instead!
#### openByClickOn : ReactElement
The second way how to open the portal. This element will be rendered by the portal immediately
with
onClick handler that triggers portal opening. How to close the portal then? The portal provides its ported child with a callback this.props.closePortal. Or you can use built-in portal closing methods (closeOnEsc, ... more below). Notice that you don't have to deal with the open/close state (like when using the isOpen prop).$3
#### closeOnEsc: bool
If true, the portal can be closed by the key ESC.
#### closeOnOutsideClick: bool
If true, the portal can be closed by the outside mouse click.
#### onOpen: func(DOMNode)
This callback is called when the portal is opened and rendered (useful for animating the DOMNode).
#### beforeClose: func(DOMNode, removeFromDOM)
This callback is called when the closing event is triggered but it prevents normal removal from the DOM. So, you can do some DOMNode animation first and then call removeFromDOM() that removes the portal from DOM.
#### onClose: func
This callback is called when the portal closes and after beforeClose.
#### onUpdate: func
This callback is called when the portal is (re)rendered.
#### target: string
Pass to render popup in a custom container instead of
document.body. The container should be found by data attribute [data-portaltarget=${props.target}]. There's also a helper component PortalTarget which creates an element with data-portaltarget={props.name}:`js
import React from 'react';
import Portal, {PortalTarget} from 'react-portal';function App() {
return (
// renders inside PortalTarget
);
}
`Tips & Tricks
- Does your modal have a fullscreen overlay and the doesn't work? There is a simple solution.
- Does your inner inner component jsx
`also need an access to
? You can't just use {this.props.children} in render method of component. You have to clone it instead:`jsx
{React.cloneElement(
this.props.children,
{closePortal: this.props.closePortal}
)}
`#### Open modal programmatically
Sometimes you need to open your portal (e.g. modal) automatically. There is no button to click on. No problem, because the portal has the
prop, so you can just set it to true or false. However, then it's completely up to you to take care about the portal closing (ESC, outside click, no this.props.closePortal callback...).However, there is a nice trick how to make this happen even without
isOpen:`jsx
Modal content
`jsx
this.refs.myPortal.openPortal()
// opens the portal, yay!
