React Flickity Component
Introduction:
A React.js Flickity component.
Install:
# you need to install flickity as peer dependency, please use v2.3.0 for best experience
npm install [email protected]
npm install react-flickity-component
Usage:
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.
// Commonjs
const Flickity = require('react-flickity-component');
// Or for ES2015 module
import Flickity from 'react-flickity-component'
const flickityOptions = {
initialIndex: 2
}
function Carousel() {
return (
<Flickity
className={'carousel'} // default ''
elementType={'div'} // default 'div'
options={flickityOptions} // takes flickity options {}
disableImagesLoaded={false} // default false
reloadOnUpdate // default false
static // default false
>
<img src="/images/placeholder.png"/>
<img src="/images/placeholder.png"/>
<img src="/images/placeholder.png"/>
</Flickity>
)
}
Example Usage:
See a codesandbox example here: https://codesandbox.io/s/qlz12m4oj6
See an example with server side rendering:
https://github.com/theolampert/react-flickity-component-example
And with typescript:
https://github.com/theolampert/react-flickity-component-example/tree/typescript
Props:
| Property | Type | Default | Description |
| -------------------- | -----------| --------|---------------------------------------------------------------|
| className
| String
| ''
| Applied to top level wrapper |
| elementType
| String
| 'div'
| Wrapper's element type |
| options
| Object
| {}
| Flickity initialization opions |
| 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. |
How it works
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 portal, react-flickity-component will directly render children. This is 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.
Use Flickity's API and events
You can access the Flickity instance with flickityRef
prop just like ref
, and use this instance to register events and use API.
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 (
<Flickity flickityRef={c => this.flkty = c}>
<img src="/images/placeholder.png"/>
<img src="/images/placeholder.png"/>
<img src="/images/placeholder.png"/>
</Flickity>
<Button onClick={myCustomNext}>My custom next button</Button>
)
}
}
