What's the download tariff on Polymer vs React (I'll admit, I haven't checked library sizes for polymer since 2014) Do they allow for this 150k initial bundle?
It's pretty small. I'm working on an internal application using Polymer 3.0-rc1 currently, with some basic Paper elements (button, input, icon, spinner, tabs, app-route). The whole app bundle (made with rollup + babel-minify) is ~90k gzipped, ~200k uncompressed.
