Make Tinder-like Card Animations with React Native


The easiest way to replicate this swiping mechanism is to use react-native-deck-swiper. This is an awesome npm package opens up many possibilities. Let’s start by installing the necessary dependencies:

yarn add react-native-deck-swiper
yarn add react-native-view-overflow
yarn add react-native-vector-icons

Although the newest React Native version (0.60.4, which we’re using in this tutorial) introduced autolinking, two of those three dependencies still have to be linked manually because, at the time of writing, their maintainers haven’t yet updated them to the newest version. So we have to link them the old-fashioned way:

react-native link react-native-view-overflow && react-native-link react-native-vector-icons

Also, React Native version 0.60.0 and above uses CocoaPods by default for iOS, so one extra step is required to have everything installed correctly:

cd ios && pod install && cd ...

After installation is complete, we can now run the app:

react-native run-ios

If you’re having issues running app with the CLI, try opening XCode and build the app through it.

Building the Card.js component

After the installation is complete and we have the app running on a simulator, we can get to writing some code! We’ll start with a single Card component, which will display the photo and the name of person.

import React from 'react'
import { View, Text, Image, ImageSourcePropType } from 'react-native'
import { shape, string, number } from 'prop-types'
import styles from './Card.styles'
const Card = ({ card }) => (
    <View style={styles.photoDescriptionContainer}>
      <Text style={styles.text}>
        {`${}, ${card.age}`}

Card.propTypes = {
card: shape({
photo: ImageSourcePropType,
name: string,
age: number,
export default Card

I am using propTypes in this and in every project I work on in React Native. propTypes help a lot with the type safety of props passed to our component. Every wrong type of prop (e.g., string instead of number) will result in a console.warn warning inside our simulator.

When using isRequired for a specific propType, we’ll get an error inside a debugging console about missing props, which help us identify and fix errors quicker. I really recommend using propTypes from the prop-typeslibrary inside every component we write, using the isRequired option with every prop that’s necessary to render a component correctly, and creating a default prop inside defaultProps for every prop that doesn’t have to be required.

Styling our cards

Let’s keep going by styling the Card component. Here’s the code for our Card.styles.js file:

import { StyleSheet, Dimensions } from ‘react-native’
import { colors } from ‘…/…/constants’
const { height } = Dimensions.get(‘window’)
export default StyleSheet.create({
card: {
/* Setting the height according to the screen height, it also could be fixed value or based on percentage. In this example, this worked well on Android and iOS. */
height: height - 300,
justifyContent: ‘center’,
alignItems: ‘center’,
backgroundColor: colors.white,
borderRadius: 5,
shadowOffset: {
width: 0,
height: 2,
shadowRadius: 6,
shadowOpacity: 0.3,
elevation: 2,
image: {
borderRadius: 5,
flex: 1,
width: ‘100%’,
photoDescriptionContainer: {
justifyContent: ‘flex-end’,
alignItems: ‘flex-start’,
flexDirection: ‘column’,
height: ‘100%’,
position: ‘absolute’,
left: 10,
bottom: 10,
text: {
textAlign: ‘center’,
fontSize: 20,
color: colors.white,
fontFamily: ‘Avenir’,
textShadowRadius: 10,

Here’s how our card looks now:

IconButton.js component

The second component for our app renders the icon inside a colored, circular button, which is responsible for handling user interactions instead of swipe gestures ( Like , Star , and Nope ).

import React from ‘react’
import { TouchableOpacity } from ‘react-native’
import { func, string } from ‘prop-types’
import Icon from ‘react-native-vector-icons/AntDesign’
import styles from ‘./IconButton.styles’
import { colors } from ‘…/…/constants’
const IconButton = ({ onPress, name, backgroundColor, color }) => (
style={[styles.singleButton, { backgroundColor }]}
IconButton.defaultProps = {
color: colors.white,
backgroundColor: colors.heartColor,
IconButton.propTypes = {
onPress: func.isRequired,
name: string.isRequired,
color: string,
backgroundColor: string,
export default IconButton

Styling our buttons

Now let’s get to styling:

import { StyleSheet } from ‘react-native’

export default StyleSheet.create({
singleButton: {
backgroundColor: ‘transparent’,
borderRadius: 50,
alignItems: ‘center’,
justifyContent: ‘center’,
shadowColor: ‘black’,
shadowOffset: {
width: 0,
height: 2,
shadowRadius: 6,
shadowOpacity: 0.3,
elevation: 2,
padding: 15,

The three buttons will look like this:

OverlayLabel.js component

The OverlayLabel component is simple Text inside a View component with predefined styles.

import React from ‘react’
import { View, Text } from ‘react-native’
import { string } from ‘prop-types’
import styles from ‘./OverlayLabel.styles’

const OverlayLabel = ({ label, color }) => (
<View style={[styles.overlayLabel, { borderColor: color }]}>
<Text style={[styles.overlayLabelText, { color }]}>{label}</Text>

OverlayLabel.propTypes = {
label: string.isRequired,
color: string.isRequired,

export default OverlayLabel

Styling the OverlayLabel

And now the styling:

import { StyleSheet } from ‘react-native’

export default StyleSheet.create({
overlayLabel: {
justifyContent: ‘center’,
alignItems: ‘center’,
padding: 10,
borderWidth: 2,
borderRadius: 10,
overlayLabelText: {
fontSize: 25,
fontFamily: ‘Avenir’,
textAlign: ‘center’,

And here’s the result:


After creating those basic components, we have to create an array with objects to fill the Swiper component before we can build it. We’ll be using some free random photos found on Unsplash, which we’ll put inside the assets folder in the project folder root.


const photoCards = [
name: ‘Austin Wade’,
age: 22,
photo: require(‘…/assets/austin-wade-ex6qfO4TPMY-unsplash.jpg’),
key: ‘caseex6qfO4TPMYyhorner’,
name: ‘Aleksander Borzenets’,
age: 28,
photo: require(‘…/assets/aleksander-borzenets-ozda-XbeP0k-unsplash.jpg’),
key: ‘ozda-XbeP0k’,
name: ‘Don Delfin Espino’,
age: 29,
photo: require(‘…/assets/don-delfin-espino-nBywXevf_jE-unsplash.jpg’),
key: ‘nBywXevf_jE-’,
name: ‘Eduardo Dutra’,
age: 30,
photo: require(‘…/assets/eduardo-dutra-ZHy0efLnzVc-unsplash.jpg’),
key: ‘ZHy0efLnzVc’,
name: ‘Wesley Tingey’,
age: 21,
photo: require(‘…/assets/wesley-tingey-TvPCUHten1o-unsplash.jpg’),
key: ‘TvPCUHten1o’,
name: ‘Gift Habeshaw’,
age: 26,
photo: require(‘…/assets/gift-habeshaw-dlbiYGwEe9U-unsplash.jpg’),
key: ‘dlbiYGwEe9U’,
name: ‘Henri Pham’,
age: 30,
photo: require(‘…/assets/henri-pham-Ml4tr2WO7JE-unsplash.jpg’),
key: ‘Ml4tr2WO7JE’,
name: ‘Nico Marks’,
age: 24,
photo: require(‘…/assets/nico-marks-mFcc5b_t74Q-unsplash.jpg’),
key: ‘mFcc5b_t74Q’,
name: ‘Sirio’,
age: 28,
photo: require(‘…/assets/sirio-Ty4f_NOFO60-unsplash.jpg’),
key: “Ty4f_NOFO60’”,
name: ‘Teymi Townsend’,
age: 30,
photo: require(‘…/assets/teymi-townsend-AvLHH8qYbAI-unsplash.jpg’),
key: “AvLHH8qYbAI’”,
name: ‘Caique Silva’,
age: 20,
photo: require(‘…/assets/caique-silva-3ujVzg9i2EI-unsplash.jpg’),
key: “3ujVzg9i2EI’”,
name: ‘David Yanutenama’,
age: 21,
photo: require(‘…/assets/david-yanutama-5AoO7dBurMw-unsplash.jpg’),
key: “5AoO7dBurMw’”,
export default photoCards

Finally, the Swiper component

Once we have the array with card data available to use, we can actually use the Swiper component.

First, we import the necessary elements and initialize the App function. Then, we use a useRef Hook, part of the new and awesome React Hooks API. We need this in order to reference the Swiper component imperatively by pressing one of the handles functions.

import React, { useRef } from ‘react’
import { View, Text } from ‘react-native’
import Swiper from ‘react-native-deck-swiper’
import { photoCards } from ‘./constants’
import { Card, IconButton, OverlayLabel } from ‘./components’
import styles from ‘./App.styles’
const App = () => {
const useSwiper = useRef(null).current
const handleOnSwipedLeft = () => useSwiper.swipeLeft()
const handleOnSwipedTop = () => useSwiper.swipeTop()
const handleOnSwipedRight = () => useSwiper.swipeRight()

When using the useRef Hook, be sure that the function calling on the actual ref (e.g., here, useSwiper.swipeLeft()) is wrapped in a previously declared function (e.g., here, handleOnSwipedLeft) in order to avoid an error on calling a null object.

Next, inside a return function, we render the Swiper component with the ref set to the useSwiper Hook. Inside the cards prop, we insert the photoCardsdata array we created earlier and render a single item with a renderCardprop, passing a single item to a Card component.

Inside the overlayLabels prop, there are objects to show the LIKE and NOPElabels while we’re swiping left or right. Those are shown with opacity animation — the closer to the edge, the more visible they are.

return (
renderCard={card => <Card card={card} />}
left: {
title: ‘NOPE’,
element: <OverlayLabel label=“NOPE” color=“#E5566D” />,
style: {
wrapper: styles.overlayWrapper,
right: {
title: ‘LIKE’,
element: <OverlayLabel label=“LIKE” color=“#4CCC93” />,
style: {
wrapper: {
alignItems: ‘flex-start’,
marginLeft: 30,

In the last section of the App.js component, we render the three buttons for handling the swipe gestures imperatively. By passing name props to the IconButton component, we’re using the awesome react-native-vector-icons library to render nice-looking SVG icons.

  <View style={styles.buttonsContainer}>


And here’s how the end result looks:

You can find the full code for this tutorial in my GitHub. The usage of this react-native-deck-swiper component is really smooth and — it definitely helps us save a lot of time. Also, if we tried to implement it from scratch, we’d most likely use the same react-native-gesture-handler API that library author used. That’s why I really recommend using it. I hope that you’ll learn something from this article!

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.
