This is a new React Native project, bootstrapped using @react-native-community/cli.

Getting Started

Note: Make sure you have completed the React Native - Environment Setup instructions till "Creating a new application" step, before proceeding.

Step 0: Install Pacakges

Install NPM Dependencies The first step is to install all JavaScript dependencies using npm or Yarn. This step ensures that all required packages are installed for the project.

Open your terminal. Navigate to the root directory of the React Native project. Run one of the following commands to install the required packages:

# using npm
npm install

# OR using Yarn
yarn install

Install CocoaPods (iOS-specific) If you are working on a macOS system and you need to run the project on iOS, you will also need to install the native dependencies via CocoaPods. CocoaPods is a dependency manager for native iOS projects.

cd ios && pod install && cd ..

Step 1: Start the Metro Server

First, you will need to start Metro, the JavaScript bundler that ships with React Native.

To start Metro, run the following command from the root of your React Native project:

# using npm
npm start

# OR using Yarn
yarn start

Step 2: Start your Application

Let Metro Bundler run in its own terminal. Open a new terminal from the root of your React Native project. Run the following command to start your Android or iOS app:

For Android

# using npm
npm run android

# OR using Yarn
yarn android

For iOS

# using npm
npm run ios

# OR using Yarn
yarn ios

If everything is set up correctly, you should see your new app running in your Android Emulator or iOS Simulator shortly provided you have set up your emulator/simulator correctly.
