React 15.4
I like React a lot, but boy. That file size is getting pretty large:http://elijahmanor.com/react-file-size/Looks to be around 45KB gzipped now, to say nothing of the parse time. It's becoming a pretty huge dependency and I wonder how much of it 90% of projects really use. Personally, I've been getting along just fine with Preact, which matches a lot of the API and is just 3KB gzipped:https://preactjs.com
