Tinder Cards for React Native

LOOKING FOR CONTRIBUTORS. I'm not currently using this in any active projects. If anyone wants to be added, please write me.

A package based on @brentvatne's awesome example, based in turn on the Tinder swipe interface.

Note: Maybe action is optional

Quick Start

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

// Tinder.js
'use strict';

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

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

let Card = React.createClass({
  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>
    )
  }
}

const Cards = [
  {text: 'Tomato', backgroundColor: 'red'},
  {text: 'Aubergine', backgroundColor: 'purple'},
  {text: 'Courgette', backgroundColor: 'green'},
  {text: 'Blueberry', backgroundColor: 'blue'},
  {text: 'Umm...', backgroundColor: 'cyan'},
  {text: 'orange', backgroundColor: 'orange'},
]

export default React.createClass({
  getInitialState() {
    return {
      cards: Cards
    }
  },
  handleYup (card) {
    console.log(`Yup for ${card.text}`)
  },
  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: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    width: 300,
    height: 300,
  },
  noMoreCardsText: {
    fontSize: 22,
  }
})

Todo (PRs welcome!)

• Show next card underneath current card
• Shadow when card is being dragged
• Example with backend
• Example with polaroids
• Submit to repos
• renderYup
• renderNope
• Testing
• Add more args to cardRemoved?
• class extends all components
