Hey friend! We are co-hosting a conference with Software Mansion, learn more.

Expo & "Create React Native App"

Create React Native App lets you build a React Native app without any build configuration. This may sound familiar to you because Expo does this as well -- when you create a project with XDE or exp you don't have to deal with Xcode or Android Studio configuration files, it just works. This guide is intended to outline some of the key differences between Expo and CRNA (create-react-native-app).

You can run create-react-native-app YourAppName and off you go. So what does not having an account mean, and what would signing up and using XDE/exp get you -- why do we require it with Expo? Having an Expo account allows you to do the following:

Yes! Open the project as you would any other Expo project using XDE and exp and it will work as expected.

If you want to add custom native code to your Expo app, you will need to use ExpoKit. With CRNA, you have two options: you can either eject to a normal React Native project, without any dependencies on Expo, or you can eject to use ExpoKit, which will allow you to continue using the Expo APIs. Read more about ejecting with CRNA here.
