Example of Pinch to Zoom Image in React Native

Zoom Image in React Native

This is an Example of Pinch to Zoom Image in React Native. We are going to use react-native-image-zoom-viewer library for the pinch to zoom effect.

While making a mobile app that has Image(s) we always need a pinch to zoom effect. It makes the App experience better as the user can easily see more details in the image by zooming it easily. We have used the image URL for the image source, you can show the image from your project folder as well. So let’s get started.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react native command line interface to make our React Native App.

If you have previously installed a global react-native-cli package, please remove it as it may cause unexpected issues:

npm uninstall -g react-native-cli @react-native-community/cli

Run the following commands to create a new React Native project

npx react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

npx react-native init ProjectName --version X.XX.X

Note If the above command is failing, you may have old version of react-native or react-native-cli installed globally on your pc. Try uninstalling the cli and run the cli using npx.

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use ImageViewer you need to install react-native-image-zoom-viewer package.

To install this open the terminal and jump into your project

cd ProjectName

Run the following command

npm install react-native-image-zoom-viewer --save

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module directory named react-native-image-zoom-viewer. –save is optional, it is just to update the react-native-image-zoom-viewer dependency in your package.json file.

Code to Zoom Image in React Native

Now Open App.js in any code editor and replace the code with the following code.


//Example of Pinch to Zoom Image in React Native

//import React in our code
import React from 'react';

//import all the components we are going to use
import {SafeAreaView, StyleSheet, View} from 'react-native';

//import ImageViewer which will help us to zoom Image
import ImageViewer from 'react-native-image-zoom-viewer';

const App = () => {
  const images = [

  return (
    <SafeAreaView style={{flex: 1}}>
      <View style={styles.container}>
          renderIndicator={() => null}

const styles = StyleSheet.create({
  container: {
    backgroundColor: '#F5FCFF',
    flex: 1,

export default App;

To Run the React Native App

Open the terminal again and jump into your project using.

cd ProjectName

1. Start Metro Bundler

First, you will need to start Metro, the JavaScript bundler that ships with React Native. To start Metro bundler run following command:

npx react-native start

Once you start Metro Bundler it will run forever on your terminal until you close it. Let Metro Bundler run in its own terminal. Open a new terminal and run the application.

2. Start React Native Application

To run the project on an Android Virtual Device or on real debugging device:

npx react-native run-android

or on the iOS Simulator by running (macOS only)

npx react-native run-ios
