React Flickity Component
=======================

Introduction:

A React.js Flickity component.

Install:

``shell


you need to install flickity as peer dependency, please use v2.3.0 for best experience


npm install flickity@2.3.0
npm install react-flickity-component
`

Usage:

V5 Updates

V5 supports react v19 and above.

V4 Updates

V4 only supports react v18 and above. V4 also comes with an esmodule bundle format to support modern frontend tooling like vite.
If you are staying on react v16, please keep using v3.

`javascript
// Commonjs
const Flickity = require('react-flickity-component');
// Or for ES2015 module
import Flickity from 'react-flickity-component'

const flickityOptions = {
initialIndex: 2
}

function Carousel() {
return (
className={'carousel'}
elementType={'div'}
options={flickityOptions}
disableImagesLoaded
reloadOnUpdate
static
>




)
}

| Property | Type | Default | Description |
| -------------------- | -----------| --------|---------------------------------------------------------------|
| className | String | '' | Applied to top level wrapper |
| elementType | String | 'div' | Wrapper's element type |
| options | Object | {} | Flickity initialization options |
| disableImagesLoaded| Boolean | false | Disable call reloadCells images are loaded |
| flickityRef | Function | | Like ref function, get Flickity instance in parent component|
| reloadOnUpdate | Boolean | false | Read next section before you set this prop. Run reloadCells and resize on componentDidUpdate |
| static | Boolean | false | Read next section before you set this prop. Carousel contents are static and not updated at runtime. Useful for smoother server-side rendering however the carousel contents cannot be updated dynamically. |

Under the hood, react-flickity-component uses a React Portal to render children slides inside a Flickity instance. The need for a portal is because after Flickity is initialized, new DOM nodes (mostly Flickity wrapper elements) would be created, this changes the DOM hierarchy of the parent component, thus any future update, whether it's originated from Flickity, like adding/removing slides, or from parent, like a prop changes, will make React fail to reconcile for the DOM snapshot is out of sync.

#64 introduced a new prop to change the underlying render method: instead of using portal, react-flickity-component will directly render children. This is to create a smoother server-side rendering experience, but please be aware using static prop possibly will cause all your future update to fail, which means adding/removing slides will definitely fail to render, so use with caution.

However there is a fail-safe option reloadOnUpdate. It means every time there is a update, we tear down and set up Flickity. This will ensure that Flickity is always rendered correctly, but it's a rather costly operation and it will cause a flicker since DOM nodes are destroyed and recreated. Please also note it means any update, either rerender of the parent, or any of the props change, will always cause an update in the Flickity component. For more information, see a detailed explanation and workaround in #147.

You can access the Flickity instance with flickityRef prop just like ref, and use this instance to register events and use API.

`javascript
// function component
function Carousel () {
const ref = React.useRef(null);

function myCustomNext = () {
// You can use Flickity API
ref.current.next()
}

React.useEffect(() => {
if (ref.current) {
ref.current.on("settle", () => {
console.log(current index is ${ref.current.selectedIndex});
});
}
}, []);

return (
ref.current = c}>




My custom next button
)
}
// class component
class Carousel extends React.Component {

componentDidMount = () => {
// You can register events in componentDidMount hook
this.flkty.on('settle', () => {
console.log(current index is ${this.flkty.selectedIndex})
})
}

myCustomNext = () => {
// You can use Flickity API
this.flkty.next()
}

render() {
return (
this.flkty = c}>




My custom next button
)
}
}
