as there is nothing stopping us now, the nodejs package in Rawhide will soon be
updated to Node.js v8.x. It also comes with npm@5 and new V8.

Note that upstream has made a lot of changes and your projects/packages might have
some issues.

I'll update nodejs in rawhide next week, if you wish to try it out sooner, it's already built here:
