That is very possible, as I know next to nothing about javascript (which, thank god, is different than java which is a performance pig due to garbage collection). From what I see of the stuff I needed to install, looks to be light weight (and therefore in theory fast, in practice we will see) but it is implied that this is a parts viewer of some kind and its extremely possible I just don’t know what I’m doing. I guess we will see if the folks writing it reply to the various posts. The code snippet in the readme.md file appears to make a server of some kind (a similar one I found on stackoverflow creates a server that outputs a “Hello World” web page successfully), but for me the code snippet errors out before starting, possibly due to something I’m not doing so I have some feeling it may do something if I knew how 
or you could be correct.
I think concentrating on fixing up the parts repository is worth doing and there is certainly lots to clean up about that. It is much less clear to me that there is much purpose in trying to improve the Qt based code as it looks like (as it has for some time) development interest in that code base has died. I’m an outsider and a relatively new user, el-j as far as I know was a key member of the original team and I expect he has a lot better idea than any of us of the chance of the Qt code going forward and it doesn’t seem that he sees much chance of that from his posts. I guess time will tell.
