Package Exports

react-spring-carousel-js

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-spring-carousel-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

react-spring-carousel-js

A performant React carousel component powered by react-spring and react-use-gesture.

Features

Extreemely performant: thanks to react-spring, you'll get a very performant results, and smooth and natural transitions with zero config.
Stateless 😏: We don't use state to update the animation: this means solid and stable animations in every moment (because no React rerender will happen during animations!).
Custom events: Use our custom events to intercept when things happen and take the experience to the next level!
Mobile first: You can swipe/drag with no config needed thanks to react-use-gesture.
Resizable: the carousel will automatically resize and adapt if the browser viewport change. Very useful when changing to landscape on mobile devices.
Fullscreen capable: we provide you the API to enter/exit from fullscreen mode! (thanks to screenful.js).
Headles UI: no more headaches trying to style the elements of the carousel. You decide every aspect of the elements of the carousel.
Totally composable: we give you the instruments (API) and you decide where to place all the elements of the carousel and how they will behave and interact.
Easy to configure: you can configure some aspects of the carousel in an easy and simple way.

Install

npm install --save react-spring-carousel-js

yarn add --save react-spring-carousel-js

Usage

At it's most basic, to start you can do:

import { useReactSpringCarousel } from 'react-spring-carousel-js'

const { carouselFragment, thumbsFragment } = useReactSpringCarousel({
  items: [
    {
      id: 'item-1',
      renderItem: <ItemComponent />,
      renderThumb: <ThumbComponent />
    },
    {
      id: 'item-2',
      renderItem: <ItemComponent />,
      renderThumb: <ThumbComponent />
    }
  ]
})

return (
  <div>
    {carouselFragment}
    {thumbsFragment}
  </div>
)

As you can see, you don't have to call the component in the traditional way but instead the main hook return the carousel fragment (which is the carousel) and the thumbs fragment (which render the list of tumbs). It's up to you to decide how and where render boths, and they're not tied in any way, so basically you can customize the UI pretty much in any way you want to!

Props

You can provide this options to better customize the behavior and the aspect of the Carousel:

Prop	Type	Default Value	Description
items	`T[]`	`[]`	You can extend the main interface - `ReactSpringCarouselItem` - by adding custom props to the item object if you need to.
withLoop	`boolean`	`false`	Set to `true` if you want to enable the infinite loop behavior
withThumbs	`boolean`	`true`	Set to false if you don't want to render the list of thumbs.
springConfig	`SpringConfig`	`config.default`	Here you can customize the properties of the `spring`.
onItemStartToChange	`VoidFunction`	`() => {}`	A `callback` triggered every time a item is about to change (slide).
onItemChange	`VoidFunction`	`() => {}`	A `callback` triggered every time a item finish sliding (the callback is called inside the `onRest` react-spring method).
shouldResizeOnWindowResize	`boolean`	`true`	Set to `false` if you don't want to resize the carousel when the browser resize. Remember that if you set `shouldResizeOnWindowResize` to false, when using the fullscreen mode the carousel will not adapt correctly after `entering`/`exiting` the fullscreen mode.
draggingSlideTreshold	`number`	`50`	Set the minimum treshold that is required to slide after the item is dragged and then released.
enableThumbsWrapperScroll	`boolean`	`true`	Set to false if you don't want to auto-scroll the list of thumbs when an item is selected. By default every time an item is selected and become the active one `react-spring-carousel-js` will automatically scroll the thumb wrapper list and will center the item.
CustomWrapper	`React.ForwardRefExoticComponent<{ children: React.ReactNode } & React.RefAttributes<HTMLDivElement>>`	`undefined`	If you want, you can provide a custom `element` that will be used as the main Wrapper element. Note that you can pass whatever element you want to, using whatever style pattern you want!
CustomThumbsWrapper	`React.FC<{ children: React.ReactNode }>`	`undefined`	If you want, you can provide a custom `element` to customize the wrapper of the thumb list. Note that you can pass whatever element you want to, using whatever style pattern you want!

Options (API)

The following options and API can be both extracted from the main hook or from the own Carousel Context (that can be imported and used inside any component rendered inside the Carousel 😏)

Option	Type	Default Value	Description
isFullscreen	`boolean`	`false`	Indicates if the carousel entered in fullscreen mode.
getIsActiveItem	`(id: string): boolean`	`false`	By providing the `id` of an item, you can check if that item the current active one.
getIsPrevItem	`(id: string): boolean`	`false`	By providing the `id` of an item, you can check if that item is the previous one in the list of items. Pretty useful if, for example, you render a list of items and want to preload on demand.
getIsNextItem	`(id: string): boolean`	`false`	By providing the `id` of an item, you can check if that item is the next one in the list of items. Pretty useful if, for example, you render a list of items and want to preload on demand.
slideToItem	`(item: number, callback?: VoidFunction): void`	`() => {}`	You can use this method to programmatically slide to a specific item. You can also pass a callback if you want to perform some action after the animation is completed. NOTE: The callback is passed and called by the `onRest()` method of `react-spring`.
getIsAnimating	`(): boolean`	`() => false`	Use this method to check if the carousel is `animating` or not. Under the hood, `react-carousel-spring-js` uses a ref to keep track of this value. We don't use a state to avoid useless re-render that could impact in the animation smoothness.
getIsDragging	`(): boolean`	`() => false`	Use this method to check if the carousel is `dragging` or not. Under the hood, `react-carousel-spring-js` uses a ref to keep track of this value. We don't use a state to avoid useless re-render that could impact in the animation smoothness.
enterFullscreen	`(elementRef?: HTMLElement): void`	`() => {}`	Use this method to enter in the `fullscreen` mode. NOTE: By default, the main wrapper of the carousel will enter in fullscreen mode, but normally you will want to put in the fullscreen mode also other elements, that's why you can pass a custom element ref.
slideToPrevItem	`(): void`	`() => {}`	Use this method slide to the `previous` item. This is useful to build your own navigation buttons. You just need to call it and that's it; the carousel itself will handle all the internal logic part (for example, if the `withLoop` property is set to `false`, when reaching the first item, if you call it it will do nothing.)
slideToNextItem	`(): void`	`() => {}`	Use this method slide to the `next` item. This is useful to build your own navigation buttons. You just need to call it and that's it; the carousel itself will handle all the internal logic part (for example, if the `withLoop` property is set to `false`, when reaching the last item, if you call it it will do nothing.)
useListenToCustomEvent	`<T>(eventName: ReactSpringCustomEvents, eventHandler: (data?: T): void): void`	`() => {}`	Use this hook to perform callback actions in your application when the carousel internal `state` change.
