I am a shiny app developer and I am not a big fan of modules. Debugging with "browser()" is not really possible and the whole thing with "session$ns", etc. ist quite complicated. Nonetheless my apps are quite efficient and not really a mess, but well ordered. I put different sites on different code files in the folder "R" with Numbers of the sites beforehand ("01_first_site.R", "02_ABC.R", ...). I can warmly recommend the "Mastering Shiny" book from Hadley Wickham.

What is the advantage of using "box::use(path)" compared with using "source()"?
I think that they're doing the same work; the source() syntax looks slightly more friendly.
