any news on bundle size? and maybe Closure Compiler compatibility for dead code elimination?
For DCE, we've started splitting some features like createClass out of the main package (https://facebook.github.io/react/blog/2017/04/07/react-v15.5...) which will reduce the bundle size for anyone not using them, regardless of how they compile their JS.
Many mobile users are on throttled connections, due to low data caps, and research has shown users stop loading a site usually after 1 second of loading time.
That means with a throttled connection, less than 8KiB overall CSS, JS and HTML can be transmitted, and with a 1Mbps connection, 128KiB can be transmitted.
How many minutes will users have to wait with React Fiber? And can it be improved in any way to get below a few seconds? Or will I have to continue to write vanilla JS to get responsive apps?
But React Fiber is doing a lot more than legacy react, so it'd be interesting to know how much larger it will get - and if it would still be performant enough.
