@react-native-community/cli

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.

run-ios

Builds your app and starts it on iOS simulator.

Options

Explicitly set the simulator to use. Optionally include iOS version between parenthesis at the end to match an exact version, e.g. "iPhone 6 (10.0)".

Default: "iPhone X"

Notes: simulator_name must be a valid iOS simulator name. If in doubt, open your AwesomeApp/ios/AwesomeApp.xcodeproj folder on XCode and unroll the dropdown menu containing the simulator list. The dropdown menu is situated on the right hand side of the play button (top left corner).

Example: this will launch your projet directly onto the iPhone XS Max simulator:

react-native run-ios --simulator "iPhone XS Max"

Explicitly set the scheme configuration to use default: 'Debug'.

--scheme [string]

Explicitly set Xcode scheme to use.

--project-path [string]

--device [string]

Explicitly set device to use by name. The value is not required if you have a single device connected.

--udid [string]

Explicitly set device to use by udid.

--no-packager

Do not launch packager while building.

--verbose

Do not use xcpretty even if installed.
