RCA

  • bundle.js increased by 1.5kB because of marked: (+2kB to 7.2kB: https://bundlephobia.com/[email protected])
  • highlight.js increased in size dramatically over the past few releases, though we're subsetting
  • polyfills increased in size. switch from fetch to unfetch helped, code-splitting removed the issue entirely
  • classnames increased in size a bit. it also isn't getting bundled optimally due to a nonstandard UMD wrapper
  • FCP was always a bit bad since only the app shell is prerendered
