When and how to: build, submit, and update an app

Name	Description	Type of testing	Requirements	When to USE
Update	Replace javascript/typescript code in mobile app (expo go or native app) Use eas update	Expo go	Expo project configuration 🕐 Testing in Expo Go 🕐	When you want to perform fast tests, you can add native libraries, but the need to be supported by expo go (check expo docs if library is supported by expo go, for example: https://docs.expo.dev/versions/latest/sdk/accelerometer/)
		Native app	App configuration 🕐 Update	When you have only typescript changes When you want to update native app
Build	Process of building native app Use eas build	Native app	App configuration 🕐 Before first build go through this: iOS - Build & deploy the iOS app 🕐 / 📱 android - Build & deploy Android app 🕐 / 📱	When you want to build native app When you have native changes, for example: adding native library changing app icons / app names adding expo plugin - https://docs.expo.dev/config-plugins/plugins-and-mods/
Submit	Process of submitting app to the stores (app store and play store) Use eas submit	Native app		When you want to submit app for testers or production users When you have created build and you want to submit it (in most cases it will go automatically build + submit)

Types of testing

Platform	Pros	Cons
Expo go	Fast Easy Automated way to distribute app	Can't test native modules that are not supported by expo go like: firebase analytics, onesignal It's little different than native app, will need additional tests after testing in expo go
Native app	Testing all native modules Supports expo plugins	Complicated build process (only for first time) Complicated distribution and installation on devices (only for first time)
