In this chapter, I gave a quick overview of some of the most interesting packaging tools, but there are many others, such as nodebob and lein-node-webkit-builder.
I made one myself (Nuwk!) that has a few thousand downloads, but currently, I have no time to follow a project that anyway is in a very early stage of development.
I guess it would be pretty cool if a frontend guy (or girl) took the time to build a decent GUI around node-webkit-builder. If you think about it, most of you should be able to do it by now. It would be an additional incentive for newbies to approach NW.js.
That said, we can move on to the next subject: debugging NW.js applications. There are many approaches to debugging, and I cannot go deep into each one, so I will simply give you an overview of the tools needed for the job.
