Quick Start

In this section, we'll use expo-cli to set up a new React Native app.

You'll need Node.js v10 or newer installed, so if you don't have it already, download the installer at nodejs.org. Choose the appropriate package for your platform and follow the instructions to install.

Installation

First, let's install expo-cli, a command-line tool for working with React Native projects.

npm install --global expo-cli

Now use expo-cli to create a new app:

expo init MyApp --template blank

cd MyApp
npm start

expo-cli may take a few minutes to download dependencies.

If you have yarn installed, Expo will ask whether you'd like to use yarn instead of npm. Either way is fine.

You should see a QR code like this after it's done:

You just created your first React Native app! Now you can install the Expo Client on iOS or Android and scan the QR code to view it.

If you see this, success! You're ready to start working on your new React Native App.

Making changes

Try changing the text in App.js, saving the file, and watching it update on your device.

Up next

Now that you have a project set up, let's jump into some of the important JavaScript language features you'll be using. If you're already familiar with each, skip to React to learn more about React. If you're already familiar with React, skip to Core Components to learn about the components provided by the React Native framework.
