Getting Started with React Native.
React Native is like React, but it uses native components instead of web components as building blocks. So to understand the basic structure of a React Native app, you need to understand some of the basic React concepts, like JSX, components,
STEP 1: Install Node.js from https://nodejs.org/en/
STEP 2: Open Node js command prompt and Install expo through command prompt.
Assuming that you have Node installed, you can use npm to install the Expo CLI command line utility:
ou can use
npm install -g expo-cli
Then run the following commands to create a new React Native project called “AwesomeProject”:
expo init ProjectName cd ProjectName npm start
Running your React Native application
Install the Expo client app on your iOS or Android phone and connect to the same wireless network as your computer. On Android, use the Expo app to scan the QR code from your terminal to open your project. On iOS, follow on-screen instructions to get a link.
Now that you have successfully run the app, let’s modify it. Open
App.js in your text editor of choice and edit some lines. The application should reload automatically once you save your changes.
