Designing Reactive SSR

A deep-dive stream transcript exploring the design challenges of server-side rendering (SSR) with async and reactivity. Covers how SSR fundamentally works (string generation), the problem of async data fetching during rendering, how suspense boundaries enable streaming SSR, hierarchical ID schemes for matching async resources across server/client rerenders, and tradeoffs of waiting vs. not waiting for async outside suspense boundaries. SolidJS internals are used as the primary reference, with comparisons to React, Svelte, Marco, and Quick.
