Creating React Native app using react-native cli

2555

5 years ago by VD

using react-native cli you can easily bootstrap a React Native project. Think this like create-react-app cli for creating React webapp.

Prerequisites

If you are on MacOS install the following prerequisites using brew

brew install node
brew install watchman
brew tap AdoptOpenJDK/openjdk
brew cask install adoptopenjdk8

Installing react-native cli

Now install react-native-cli globally by running the following command

npm install -g react-native-cli

Once installed you can cross check by running the following command

$ react-native -v
react-native-cli: 2.0.1
react-native: n/a - not inside a React Native project directory

Create your first React Native application

Once you have cli successfully installed, you can run the following command to create a React Native application

react-native init <your project name>

Example

react-native init AwesomeProject

On successful creation of project, you should see logs like following

MacBook-Pro-6:rn experimental$ react-native init AwesomeProject
This will walk you through creating a new React Native project in /Users/experimental/githome/rn/AwesomeProject
