Showcase of an Expo app written in TypeScript.
@types/expois now deprecated in favor of definition types includes with the
expopackage. TypeScript FTW!
You don't need to install any global npm packages for this repo.
expo-cliis included as a dev dependency.
There are a surprising amount of of warnings when installing Node packages, because of peer dependencies not being correct. My guess is that the Expo team has a tough time getting all the added React Native libraries to play well together. This app seems to run fine, so I believe it's safe to ignore the warnings.
Start the local server. This will give you a QR code that you can scan using the Expo Client app on your mobile device.
If you're on a Mac and have Xcode installed, you can run the app using the iOS Simulator with the following command. I am sure you can do something similar with Android.
When upgrading Expo,
expo-cliwill also upgrade the versions of all the package that it knows about. This list naturally includes all the
expo-packages, but also a few more. Do not change the version numbers of the known packages. Unknown packages may be upgraded. More info in my blog post Upgrade an Expo App.

If you have issues running the app it may help clearing the React Native packager cache. Use the command
yarn expo start --clearto do this.
