Bootstrap all devices apps

Is it possible to have bootstrap be used on a mobile app, desktop app and a website or web app while still been able to use the server actions and have the correct layout for the mobile apps etc. (All in the same project instead of 2 separate ones)

If I start a mobile app I can’t create actions I haven’t tried the other way around yet but hoping it works if it does will this create any issues when submitting it to anything like publishing the site to the hosting company and databases etc and then the platforms like iOS App Store?

Also hoping this will solve the cors
