I read the standalone deployment and I worry about something: bundle size. I am using Typescript so I dont want to have those extra files in the bundled application.
Where can I read about this details? I don’t know what the packager is doing and if I should worry about this or not.
Which extra files? In general, the code that a production user will download is minified JS – the typescript will already have been compiled to JS.
Expo takes a snapshot of your JS code and includes in the IPA/APK when you build one so that users can use the app right away without having to have a network connection or wait for stuff to load over the air. But this typically is only a small fraction of the size of the app in the app store.
