Don't be shy, share yours if you've done something awesome with it! ![react-native-snap-carousel archriss aix](https://i.imgur.com/pPm0csc.gif) ![react-native-snap-carousel archriss aix](https://i.imgur.com/UFsPlz2.gif) ![react-native-snap-carousel](https://i.imgur.com/Fope3uj.gif) ![react-native-snap-carousel](https://i.imgur.com/WNOBYfl.gif) ![react-native-snap-carousel](https://i.imgur.com/sK5DKaG.gif) --- ## :handshake: Maintainers wanted Hey there, Creating and maintaining this plugin has been a fun ride that started in 2016. We thank you all for your appreciation and for making the most out of it! You've motivated us to spend countless hours improving the plugin, and made us happy to give back to the Open Source community. Put simply, we love this project. However we currently aren't able to give it the love it deserves and the care it requires. **If you have enough time and knowledge, and want to become a maintainer, please let us know**. ### 💡 **[Just head there if you're interested](https://github.com/archriss/react-native-snap-carousel/issues/632).** We're not abandoning the ship, but we need more people to help us keep it alive and well! --- ## Usage ```bash $ npm install --save react-native-snap-carousel ``` If you're using Typescript you should also install type definitions: ```bash $ npm install --save @types/react-native-snap-carousel ``` ```javascript import Carousel from 'react-native-snap-carousel'; export class MyCarousel extends Component { _renderItem = ({item, index}) => { return ( { item.title } ); } render () { return ( { this._carousel = c; }} data={this.state.entries} renderItem={this._renderItem} sliderWidth={sliderWidth} itemWidth={itemWidth} /> ); } } ``` ## Example Here are simple examples that can be edited in real time in your browser: - https://snack.expo.io/@vitkor/carousel-simple-example - https://snack.expo.io/@bd-arc/react-native-snap-carousel-%7C-example-with-custom-interpolations You can also find a more in-depth (read "complex") one in the [`/example` folder](https://github.com/archriss/react-native-snap-carousel/tree/master/example). ![react-native-snap-carousel](https://i.imgur.com/pZincya.gif) ## Props, methods and getters In order to let you to create mighty carousels and to keep up with your requests, we add new features on a regular basis. Consequently, the list of available props has become really huge and deserves a documentation of its own. ### :books: [Documentation for "Props, methods and getters"](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/PROPS_METHODS_AND_GETTERS.md) ## Layouts and custom interpolations ### Built-in layouts In version `3.6.0`, we've added two new layouts on top of the original one: the first one is called 'stack' since it mimics a stack of cards, and the other one is called 'tinder' since it provides a Tinder-like animation. You can choose between the three of them using [the new prop `layout`](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/PROPS_METHODS_AND_GETTERS.md#style-and-animation) and you can modify the default card offset in the 'stack' and 'tinder' layouts with [prop `layoutCardOffset`](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/PROPS_METHODS_AND_GETTERS.md#style-and-animation). ![react-native-snap-carousel default layout](https://i.imgur.com/e1WbZcu.gif) ```javascript ``` ![react-native-snap-carousel stack layout ios](https://i.imgur.com/c7pU4rT.gif) ![react-native-snap-carousel stack layout android](https://i.imgur.com/AnruacR.gif) ```javascript ``` ![react-native-snap-carousel tinder layout ios](https://i.imgur.com/D9QyTzb.gif) ![react-native-snap-carousel tinder layout android](https://i.imgur.com/ab1TI4e.gif) ```javascript ``` A few things worth noting: * As you can see, the effect had to be inverted on Android. This has to do with [a really annoying Android-specific bug](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/CUSTOM_INTERPOLATIONS.md#android). * Even though the new layouts have been created with horizontal carousels in mind, they will also work with vertical ones \o/ * :warning: **You should NOT use `stack` or `tinder` layouts if you have a large data set to display.** In order to avoid rendering issues, the carousel will use a `ScrollView` component rather than a `FlatList` one for those layouts (see [prop `useScrollView`](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/PROPS_METHODS_AND_GETTERS.md#behavior)). The tradeof is that you won't benefit from any of `FlatList`'s advanced optimizations. See [this issue](https://github.com/archriss/react-native-snap-carousel/issues/262) for workarounds; or you may want to implement your own [custom interpolation](#custom-interpolations). ### Custom interpolations On top of the new layouts, we've exposed the logic we used so that users can create their own awesome layouts! If you're interested, take a deep breath and dive into the dedicated documentation. ### :books: [Documentation for "Custom interpolations"](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/CUSTOM_INTERPOLATIONS.md) Here are a few examples of what can easily be achieved (you can explore [the source code](https://github.com/archriss/react-native-snap-carousel/blob/master/example/src/utils/animations.js) and try it live in [the provided example](https://github.com/archriss/react-native-snap-carousel/tree/master/example)): ![react-native-snap-carousel custom layout](https://i.imgur.com/OrdLsCM.gif) ![react-native-snap-carousel custom layout](https://i.imgur.com/slnTbyG.gif) ![react-native-snap-carousel custom layout](https://i.imgur.com/kDx3xTc.gif) ## `ParallaxImage` component Version `3.0.0` introduced a `` component, an image component aware of carousel's current scroll position and therefore able to display a nice parallax effect (powered by the native driver to ensure top-notch performance). ### :books: [Documentation for "`ParallaxImage` component"](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/PARALLAX_IMAGE.md) ![react-native-snap-carousel parallax image](https://i.imgur.com/6iIb4SR.gif) ## `Pagination` component Starting with version `2.4.0`, a customizable `` component has been added. You can see below how it looks like with its default configuration. ### :books: [Documentation for "`Pagination` component"](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/PAGINATION.md) ![react-native-snap-carousel pagination](https://i.imgur.com/FLQcGGL.gif) ## Tips and tricks We've gathered together all the useful tips and tricks. There is a bunch of them, which makes **this section a must-read!** ### :books: [Documentation for "Tips and tricks"](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/TIPS_AND_TRICKS.md) ## Known issues **Make sure to read about the known issues before opening a new one**; you may find something useful. ### :books: [Documentation for "Known issues"](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/KNOWN_ISSUES.md) ## Important note regarding Android ![react-native-snap-carousel android](https://i.imgur.com/03iuB2Um.jpg) Android's debug mode is a mess: timeouts regularly desynchronize and scroll events are fired with some lag, which completely alters the inner logic of the carousel. **On Android, you *will* experience issues with carousel's behavior when JS Dev Mode is enabled, and you *might* have trouble with unreliable callbacks and loop mode when it isn't**. This is unfortunate, but it's rooted in various flaws of `ScrollView`/`FlatList`'s implementation and the miscellaneous workarounds we had to implement to compensate for it. :warning: **Therefore you should always check if the issue you experience also happens in a production environment. This is, sadly, the only way to test the real performance and behavior of the carousel.** > For more information, you can read the following notes: ["Android performance"](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/KNOWN_ISSUES.md#android-performance) and ["Unreliable callbacks"](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/KNOWN_ISSUES.md#unreliable-callbacks). ## Important note regarding iOS ![react-native-snap-carousel ios](https://i.imgur.com/npuiUSbh.png) :warning: When debugging with the iOS simulator, **you're only one "Cmd + T" away from toggling "Slow Animations"**. If carousel's animations seem painfully slow, make sure that you haven't enabled this setting by mistake. ## Roadmap - [ ] Add [more examples](https://github.com/archriss/react-native-snap-carousel/issues/257) - [ ] Base the plugin on a component less buggy than `FlatList` - [X] Implement different layouts and allow using custom interpolations - [X] Implement both `FlatList` and `ScrollView` handling - [X] Add the ability to provide custom items animation - [X] Implement 'loop' mode - [X] Improve Android's behavior - [x] Add parallax image component - [x] Base the plugin on `FlatList` instead of `ScrollView` - [x] Add alignment option - [x] Add pagination component - [x] Add vertical implementation - [x] Handle device orientation event (see [this note](https://github.com/archriss/react-native-snap-carousel/blob/master/doc/TIPS_AND_TRICKS.md#handling-device-rotation)) - [x] Add RTL support - [x] Improve momemtum handling - [x] Improve snap on Android - [x] Handle passing 1 item only - [x] Fix centering ## Credits Written by [Benoît Delmaire](https://fr.linkedin.com/in/benoitdelmaire) ([bd-arc](https://github.com/bd-arc)) and [Maxime Bertonnier](https://fr.linkedin.com/in/maxime-bertonnier-744351aa) ([Exilz](https://github.com/Exilz)) at [Archriss](http://www.archriss.com/).
