Once the development server is up and running, you’ll see this. Now, let’s follow the suggestion and execute these two commands to switch to the newly created directory and launch the development server: cd MyAmazingApp Now sit back and relax while it’s downloading and installing a bunch of packages. That’s all sounds great, right? Let’s try it out and create a new mobile app! That will install Create React Native App globally.
To install Create React Native App execute the following in your Terminal app:. This command should output Node version that you just installed. Go to, download and install Node.js version for your platform.Īfter you done open your Terminal app and execute the following to make sure Node.js was installed: node -v. Whether you have OS X, Windows or Linux there is only one simple step: No Xcode or Android Studio, no SDKs or anything like that. The only thing that we’re going to need to set up to get started with Create React Native App and build mobile apps on any platform is Node.js. 
You start coding, and the app automatically refreshes every time you make changes. Then, you launch Expo mobile app on your phone and scan a special QR code outputted by Create React Native App to run the app on your phone. First, you create a new app with Create React Native App. To install it execute the following in your Terminal app:. It uses Expo SDK, which means you can run your apps directly on your phone with Expo mobile app. You can test your projects as you code, and share them with anyone if you’d like.Ĭreate React Native App lets you create React Native apps with no build configuration. Expo mobile appĮxpo mobile app lets you preview projects built on Expo. That means you don’t need to use Xcode or Android Studio, or write any native code, and it also makes your pure-JS project very portable because it can run in any native environment containing the Expo SDK. Expo SDKĮxpo SDK is a native-and-JS library which provides access to the device’s system functionality (things like the camera, contacts, local storage, and other hardware). All thanks to Expo and Create React Native App! What is ExpoĮxpo is a platform on top of React Native that lets web developers build truly native apps that work on both iOS and Android by writing them once in just JavaScript. Now you can build React Native apps on any platform including OS X, Windows, and Linux without having to install Xcode or Android Studio.
