Creating a React Native project with Expo CLI is a straightforward process. Here's how you can do it:
1. Install Expo CLI
First, you need to install Expo CLI globally on your system. You can do this using npm or yarn:
npm install -g expo-cli
or
yarn global add expo-cli
2. Create a New Project
Once Expo CLI is installed, you can create a new project using the expo init
command. This will prompt you to choose a template for your project.
expo init my-new-project
Replace my-new-project
with your desired project name.
3. Select a Template
You will be presented with several template options, including:
- blank: A completely empty project.
- tabs: A basic app with multiple tabs.
- blank (TypeScript): A blank project using TypeScript.
- tabs (TypeScript): A basic app with multiple tabs using TypeScript.
Choose the template that best suits your needs.
4. Start the Development Server
Once the project is created, you can start the development server using the expo start
command:
cd my-new-project
expo start
This will open a browser window with a QR code and a link to access your app in the Expo Go app.
5. Run the App
To run the app on your device, scan the QR code using the Expo Go app. Alternatively, you can click the link to open the app directly in the Expo Go app.
6. Develop Your App
Now you can start developing your React Native app using the provided template. You can edit the code in your project directory and the changes will automatically reflect in the running app.
7. Build and Deploy
Once you are ready to deploy your app, you can use Expo CLI to build and deploy your app to the App Store or Google Play Store.
Example:
expo build:ios
This will build your app for iOS and create a .ipa
file that you can then upload to the App Store.
