I read: “We Stopped Using RSC on TanStack.com” and it’s incredible.
They were shipping 1.1 MiB of JavaScript to the browser to render markdown and syntax highlight code examples — in the browser.
They moved this work to the server (good) using React Server Components (bad).
RSC proved to be unbearable, even by TanStack standards. They then wrote their own markdown parser and syntax highlighter, and despite using SSR for the initial page load, they’re back to rendering markdown in the browser.
At no point in this palaver did anyone stop to ask, why are we re-rendering the same markdown for every request?
