Installation — Vue Native You don't need to manually install the Expo client on your emulator/simulator, because Expo CLI will do that automatically. See the next sections of this guide. If the Play Store version of the Expo Client App is installed on your test device, uninstall it. expo init AwesomeProject cd AwesomeProject npm start # you can also use: expo start Expo 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). 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. .bash_profile is specific to bash. If you're using another shell, you will need to edit the appropriate shell-specific config file.
We quickly realized that Expo is optimized for a particular stack, and YMMV with others. We got TypeScript set up but had to work through some obscure build errors, which continued to occur as long as we were working with Expo: “Building JavaScript bundle: error [object Object]”. We solved these by trial and error. (The main TypeScript gotcha was that after setting up ./src and ./dist directories, “assets” needed to be both at the root and under ./dist.)
The easiest way to install Xcode is via the Mac App Store. Installing Xcode will also install the iOS Simulator and all the necessary tools to build your iOS app.
This bundle is not signed and cannot be submitted to iTunes Connect as-is; you'll need to manually sign it if you'd like to submit it to Apple. Fastlane is a good option for this. Also, Expo will do this for you if you don't need to build this project from source.
That’s where ExpoKit comes into play. When you choose to eject from a project, you’re given the option of including ExpoKit as part of the ejected project. Including ExpoKit will ensure that all of the Expo dependencies being used in your app will continue to work, and also give you the ability to continue using all the features of the Expo SDK, even after the app has been ejected.
