RO-REACT-NATIVE-SWIPER
(based on leecade repository)

The best Swiper component for React Native.

npm version npm version

ro-react-native-swiper

Library based on this no longer maintained.
The goal is to try to carry on this library that personally accompanied me in the last years of development in the React Native world.
Since the library of leecade has not been updated for years and so many people have opened issues, so I decided to create a new package and try to keep this library up to date.
Issues and PRs are always well-liked!

Supported ScrollResponder

onTouchEnd e / state / context function You could hold the touch start for a long time
onResponderRelease e / state / context function When lifting up - you could pause forever before * lifting

Note: each ScrollResponder be injected with two params: state and context, you can get state and context(ref to swiper's this) from params, for example:

var swiper = React.createClass({
  _onMomentumScrollEnd: function (e, state, context) {
    console.log(state, context.state)
  },
  render: function() {
    return (
      <Swiper style={styles.wrapper}
      onMomentumScrollEnd ={this._onMomentumScrollEnd}
     ...
      </Swiper>
    )
  }
})

Examples

$ cd examples
$ npm i
$ react-native run-ios

Quick start with examples.

Development

$ cd examples
$ yarn
$ yarn start
$ react-native run-ios

Then launch simulator to preview. Note that you just need to edit the source file src/index.js, the change will auto sync to examples.

After development, you should add test for your modification and make all tests passed to prevent other contributors break the feature in the future accidentally. We use detox + jest for e2e test now, you can read Detox for more detail.
