It's normally slightly larger on average. I get you're joking, but the joke doesn't even make sense. A full build of LLVM + Clang is 15-20Gb, and yet, weirdly, IOS apps are not all that size.
Ah apologies, I thought it was just a "hoho isn't node_modules big" comment. Yeah, its output: 150Mb seems hyperbole, but afaics it's not far off an order of magnitude larger than a normal React app.
