react-native-swipe-cards v0.1.1

Swipe Cards for React Native

A package based on @brentvatne's awesome example.

Quick Start

1. npm install --save react-native-swipe-cards
2. Create a module e.g. SwipeCards.js
3. Import it import SwipeCards from './SwipeCards.js'
4. Render it <SwipeCards style={{flex: 1}} />

// SwipeCards.js
'use strict';

import React, { Component } from 'react';
import {StyleSheet, Text, View, Image} from 'react-native';

import SwipeCards from 'react-native-swipe-cards';

class Card extends React.Component {
  constructor(props) {
    super(props);
  }

  render() {
    return (
      <View style={[styles.card, {backgroundColor: this.props.backgroundColor}]}>
        <Text>{this.props.text}</Text>
      </View>
    )
  }
}

class NoMoreCards extends Component {
  constructor(props) {
    super(props);
  }

  render() {
    return (
      <View>
        <Text style={styles.noMoreCardsText}>No more cards</Text>
      </View>
    )
  }
}

export default class extends React.Component {

      ]
    };
  }

  }
  handleNope (card) {
    console.log(`Nope for ${card.text}`)
  }
  handleMaybe (card) {
    console.log(`Maybe for ${card.text}`)
  }
  render() {
    // If you want a stack of cards instead of one-per-one view, activate stack mode
    // stack={true}
    return (
      <SwipeCards
        cards={this.state.cards}
        renderCard={(cardData) => <Card {...cardData} />}
        renderNoMoreCards={() => <NoMoreCards />}

        handleYup={this.handleYup}
        handleNope={this.handleNope}
        handleMaybe={this.handleMaybe}
        hasMaybeAction
      />
    )
  }
}

const styles = StyleSheet.create({
  card: {
    justifyContent: 'center',
    alignItems: 'center',
    width: 300,
    height: 300,
  },
  noMoreCardsText: {
    fontSize: 22,
  }
})
