Caching to speed up build process

[aahoo]

I have been using gulp for some time. For the same reasons you mentioned in your css trick article, I decided to switch to npm scripts. One thing I noticed is that the build speed is quite slow after the first build compared to how it was when I used gulp. Is there any way to speed this up? perhaps some caching ...

+1, or skipping unchanged files (onwatch does this, but also for the non-watching tasks).
