Expo workflow 📖

As we are using the expo managed workflow, the entirety of our application is just a JS bundle. This JS bundle then operates within the native ecosystem of the Expo app. The expo app contains all the native code we require and so there is no need to compile it ourselves.

During development you use the Expo client which is available from the app store. You will also require the expo-cli to be installed in your terminal. The expo client listens to the JS bundle server on your machine, which is run using the command expo start.

As you make changes to the code it automatically hot reloads within the client.
