Hi! You've found the source code for my website.
The other thing that makes the site feel snappy is resource preloading. As soon as you hover an (internal) link, all the resources needed to load the linked page are fetched, so that chances are higher that the resources have already loaded once you click the link.
I'm pleased to report that it took me fewer than one thousand hours to configure webpack, babel, and friends to do what I wanted.
That's about it. It's MIT licensed; feel free to grab anything that you find interesting.
