react-native-simple-gesture

Wrapper for React Native gestureState that provides information about the type of gesture using a simple plain english API

Usage

1. Run npm install react-native-viewpager --save
2. Code like this:

import React from 'react-native';
import SimpleGesture from 'react-native-simple-gesture';
let { PanResponder, View, Text } = React;

class SuperAwesomeComponent extends React.Component {

  componentWillMount() {
    this._panResponder = PanResponder.create({
      // Only respond to movements if the gesture is a swipe up
      onMoveShouldSetPanResponder: (e, gs) => {
        let sgs = new SimpleGesture(e,gs);
        return sgs.isSwipeUp();
      }
    });
  }

  render() {
    return(
      <View { ...this._panResponder.panHandlers }>
        <Text>I'm gonna respond to swipes that go up</Text>
      </View>
    )
  }

}

What You Can Do

Relative Gesture Distance

Get the gesture distance relative to device screen size

let sgs = new SimpleGesture(e, gs);
console.log('Swiped ', sgs.relativeGestureDistance.x*100, '% of the screen horizontally');
console.log('Swiped ', sgs.relativeGestureDistance.y*100, '% of the screen vertically');

So far I've only written swipe tests. Gestures beyond swipes are next.
