About the run_app() function

When launching the app, you might have noticed that the dev/run_dev.R function calls run_app(), which has the following structure:

This function might looks a little bit weird, but there’s a long story behind it, and you can read more about it there.

But long story short, this combination of with_golem_options & golem_opts = list(...) allows you to pass argument to the function to be used inside the application, from UI or from server side, which you can get with get_golem_options().

The idea is to provide more flexibility for deployment on each platform you want to run your app on.
