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
Run the following commands to create a new React Native projectnpm install -g react-native-cli
This will make a project structure with an index file named App.js in your project directory.react-native init ProjectName
Open App.js in any code editor and replace the code with the following code.
App.js
