Is there any way to make my svelte web app to run locally on iOS?

I have developed an app using svelte and have uploaded it to a server. Since it contains private information, I cannot share the domain with other people. So basically, the web app should be private.

But if I want to make other people use my webapp, how can I do that? In a PC, I can give them the source code and make them locally build their webapp on their localhost:3000 using npm-run dev.

How can I achieve this on a mobile device like Android or iOS?
