Not that it makes fast minification (which I don't care that much about, I minify only on deploy, and it's a small % of the time it takes), but it does allow for a very fast workflow in dev mode: auto reload seems almost instant even with heavy transpiling.

I only mention it because I assume people look at this articles and think about their dev process speed as well.

If you haven't, give it a try: it's from the Vue author, so it's really clean, but works with react as well.
