Duncan, I don’t think it is a particularly clever or efficient example, but my package exCon does some of what you describe.  Additional disclaimer: I’m not very good at serious Javascript, and find the scoping rules challenging.  Even so, exCon works pretty well on large data sets.  But you may be more interested in the infrastructure aspects.

The gathering of separate .js files, minifying and deployment are handled in the main function exCon.R.  Javascript  and html files in inst/extdata.

Can anyone point me to other R packages containing htmlwidgets that do this "properly", or point to instructions for the standard workflow for Javascript library development outside of R that I could adapt?
