Generation of QR Code in React Native

If we have to share any small data between different users, we can use the QR Code. Generation of QR Code in React Native is very easy as we just have to install react-native-svg and react-native-qrcode-svg package, which will provide <QRCode/> component to make QRCode.

QR Code is known as Quick Response Code is a trademark for two-dimensional barcode. QR Code is a machine/camera readable block enabled code for encoding numeric value and alphabetic value. The QR Code stores information within a block of images and can store multiple types of information.

Render Using

In this example we are making an TextInput to get the value for QR Code and after clicking on “Generate QR Code” it will generate the QR Code.

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 init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

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

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

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

Installation of Dependency

Open the terminal and jump into your project

1. We need to install react-native-svg dependency to have svg support

2. To use QRCode you need to install react-native-qrcode-svg dependency

This command will copy all the dependencies into your node_module directory. –save is optional, it is just to update the react-navigation dependancy in your package.json file.

CocoaPods Installation

After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the library but need to install pods. To install the pods use

Code for the Generation of QR Code

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


To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).
