If it were only that easy. Large mature projects often have much more complicated build steps than just invoking npm, especially if you want to build incrementally so you can edit/run/debug faster than the 15+ minutes it takes to do a full build. Dev modes, logging, minimization etc. are now easily as complex as 90's era C/C++ builds.
