Install the React Native Expo set up a React Native Expo --Template Tabs

 The command npx create-expo-app is used to quickly scaffold a new React Native project using Expo. Here's a step-by-step guide on how to use it and what it does:

1. Install Node.js (if not already installed):

  • First, make sure that you have Node.js installed on your system, as npx comes with it. You can check by running:
  • node -v
    npm -v

    If you don't have Node.js, download it from the official website and install it.

2. Create a New Expo Project:

  • Open a terminal or command prompt and run: 
    npx create-expo-app my-app
  • Replace my-app with your desired project name. After running this command, the CLI will create a new directory with your app's name, download all the required dependencies, and set up the project structure.

3. Navigate to Your New Project:  
Change into the newly created directory: cd my-app

4. Start the Project
To start the project, simply run: npx expo start

This will open Expo Developer Tools in your browser, and you can run the app on your phone or simulator.

  • If you want to run it on your physical device, you can scan the QR code using the Expo Go app available on the App Store or Google Play.

Additional Options: Template Selection: You can specify a template when creating a new app by using the --template option.

For example:
npx create-expo-app my-app --template tabs

This will create a new app with the "tabs" navigation template.

Tips:

  • Expo Documentation: You can refer to the official Expo docs for more information about developing with Expo: Expo Docs.
  • Upgrading Expo: If Expo releases a new version, you can upgrade your app with expo upgrade.

That's it! You now have a fully functional React Native app scaffolded by Expo.
