Dependencies are the killer for webapps as a whole, and the general deficiency of web platform APIs is a big part of the problem. Want internationalization? Better compile ICU and ship 5+mb worth of code and data with every app, because the web platform is an absolute disaster for anyone who doesn't speak English. Want cryptography? Well, you can get it as long as you rewrite all your code to call out to JS and use async APIs for a synchronous operation. Want to decompress GZIP or Brotli? Time to compile those too and ship big blobs because the browser won't let you access its compression codecs either.
