What is @react-native-community/cli?
The @react-native-community/cli package is a command-line tool that provides a set of tools to manage and automate tasks in React Native applications. It is designed to streamline the process of initializing, developing, and testing React Native apps. It offers functionalities such as starting a development server, linking native dependencies, and more.
What are @react-native-community/cli's main functionalities?
Initializing a new React Native project
This command sets up a new React Native project named 'AwesomeProject'. It creates a directory with the project name, installs the necessary dependencies, and sets up a basic React Native project structure.
npx react-native init AwesomeProject
Running the React Native application
These commands are used to compile and run your React Native app on Android and iOS devices or emulators. 'run-android' targets Android devices, while 'run-ios' targets iOS devices.
npx react-native run-android
npx react-native run-ios
Linking native dependencies
This command automatically links native dependencies in your project. It scans the project for native modules and configures them for use with React Native, simplifying the manual linking process.
npx react-native link

expo-cli
Expo CLI is a command-line tool that provides a set of tools similar to @react-native-community/cli but focuses on projects using the Expo framework. It simplifies the process of developing, building, and deploying React Native apps without needing to open Xcode or Android Studio. Compared to @react-native-community/cli, Expo CLI offers a more managed environment, which can be advantageous for beginners or for projects that can benefit from Expo's additional services and APIs.
ignite-cli
Ignite CLI is a React Native toolchain that helps in initializing and managing React Native projects with additional boilerplates, plugins, and more. It offers a more opinionated setup compared to @react-native-community/cli, including pre-configured boilerplates, plugins, and best practices out of the box. This can help speed up development and enforce consistency across projects.

.
Default: "iPhone X"
