React Native Example to Take Screenshot Programmatically

Here is an Example to Take Screenshot Programmatically in React Native. To take Screenshot of your screen we have an inbuilt Screenshot option provided by mobile manufacturers but you can also make this in your own Application too. To take a Screenshot we will use a very good library called react-native-view-shot. Which provides captureScreen API which is very easy to use.

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

To use captureScreen we need to install react-native-view-shot package.

To install this open the terminal and jump into your project

Run the following command

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module the directory named react-native-view-shot.

–save is optional, it is just to update the react-native-view-shot 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. So to install pods use

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

App.js

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).
